Method and system for tracking and managing animals and/or food products

[0001] This is a continuation of U.S. patent application Ser. No. 12/425,286, filed Apr. 16, 2009 now U.S. Pat. No. 7,836,850, which is a continuation of U.S. patent application Ser. No. 11/336,638, filed Jan. 19, 2006, now issued as U.S. Pat. No. 7,681,527, which claims the benefit of the earlier filing date of U.S. Provisional Application No. 60/645,462, filed Jan. 19, 2005, all of which are incorporated herein by reference.

[0002] The present disclosure concerns embodiments of a method and system, particularly a computerized data management method and system, for securely collecting, storing and providing information concerning food animals, including, but not limited to: animal feed information, animal location information, drug treatment information, and/or information concerning food products made from such animals.

[0003] Currently, the beef industry is the largest sector of the agriculture economy of the United States. The industry includes nearly one million cattle producers. Many people envision the beef industry comprising expansive ranches and large cattle herds. In reality, the herd size of the average beef producer is less than 35 animals. Because of the sheer number of producers and their varying herd sizes, beef producers typically operate their production and marketing practices independently of one another and are rarely aligned with a common downstream specification. Cattle specifications are market descriptors of carcasses and live cattle that establish parameters such as the size, weight, age, sex, and type of feed provided to the animals. Specification details vary widely throughout the industry. As such, the beef supply chain has traditionally operated in an adversarial and segmented marketplace, rendering information sharing difficult.

[0004] Nevertheless, approximately 80% of all U.S. beef eventually pass through one of 400 large commercial feedyards, which prepare cattle to be harvested and made into beef products by major packing companies. Notably, these large feedyards generally have the capacity to handle 8,000 or more head of cattle at any given time. Other types of animals raised for meat also generally spend time in commercial feedyards in preparation for slaughter.

[0005] Despite advancements in vaccines and other medicines, animals at feedyards may be exposed to and/or spread diseases that are harmful to people. In December 2003, the first case of bovine spongiform encephalopathy (BSE) or “mad cow” disease was reported in the U.S. Mad cow disease is a brain disease that kills cattle and may be transmitted to people who eat meat from infected cattle.

[0006] Concern over mad cow disease and other animal diseases that may affect people, particularly those labeled “foreign animal diseases” (FADs), have caused consumers to demand additional food safety and traceability assurances. These demands have served as a catalyst among food retailers to encourage, and in some cases mandate, that suppliers provide detailed information on the source of their products. For example, major retailers such as McDonalds®, Wal-Mart® and others have recently announced goals to require their beef supply to be fully traceable to the herd of origin. Doing so protects individuals from disease and allows potentially infected cattle to be treated in a manner appropriate to the situation. Treatment of diseased cattle can include treatment with suitable drugs, quarantine, and, if necessary, slaughter to prevent the disease from spreading further.

[0007] The lack of a fully traceable system has cost the beef industry billions of dollars. Other livestock industries also have suffered. When a diseased animal is discovered, there currently is no way to properly identify animals that have been intimately associated with the diseased animal so as to require appropriate treatment in a complete and timely manner. Thus, every animal is suspected of being infected with the disease and is treated in a like manner. Ultimately, the discovery of even a single diseased animal can affect an entire livestock industry.

[0008] For example, as a result of a case of mad cow disease in a U.S. cow, U.S. beef exports were ceased to many countries. This caused the beef industry to lose approximately $4.5 billion in export revenues. While the U.S. produces the safest beef supply in the world, international trade policy and consumer fears demand that every precaution be in place to ensure that the transmission of animal diseases is mitigated. Thus, a fully traceable system would be useful to identify the individual animals and groups that have commingled with a diseased animal. Then, only those animals that are diseased or have shared a location with the infected animal need be quarantined. Other healthy animals would still be available to move normally in commerce, e.g., to be bought, sold, shipped, etc.

[0009] Hence, there is a need for an animal tracking system that takes advantage of current commercial systems, is cost-effective, and adds value to the process. There also is a need for methods and systems for tracking animal movement in the normal stream of commerce, while protecting the confidentially of collected data and insuring the accuracy of the collected data.

[0010] Disclosed herein are embodiments of an Animal Identification Framework (AIF) that may address some or all of the deficiencies of systems proposed by the U.S. government, such as the National Animal Identification System (NAIS) proposed within the United States Animal Identification Plan (USAIP). Although some form of tracking system is needed, the proposed government-controlled system regulates the movement of essentially the entire healthy food animal population and thus risks impeding the normal movement of animals in commerce. Without the proper functionality, the NAIS could fail implementation and/or substantially reduce the efficiency of the food supply chain.

[0011] Some disclosed embodiments incorporate computerized data management to timely track the location of animals. For example, some embodiments provide real-time, data management capability while protecting the confidentiality of certain data, all without interfering with typical animal commerce. In fact, some embodiments provide animal information that aids commerce, such as by improving the movement and merchandising of animals. In addition, certain embodiments allow the use of multiple animal identifiers, as opposed to the single animal identifier proposed by the NAIS. These identifiers and other data can be associated with a single database animal identifier for each animal. The animal identifiers can be encoded into physical devices and/or be physical characteristics associated with the animals. Examples of such devices include RFID tags, RFID implants, RFID boluses, visual devices, bar code devices, other useful devices now known or hereafter discovered, and combinations of such devices. Examples of physical characteristics include brands, retinal scans, DNA profiles, other useful physical characteristics now known or hereafter discovered, and combinations of such physical characteristics. Certain embodiments also allow distinguishing between animals that may have occupied a particular location. For example, animals that were not intimately associated with a particular diseased animal can be distinguished from animals that were potentially intimately associated with the diseased animal. It may be possible, therefore, to avoid the cost of treating the former group. In contrast, the NAIS does not allow for positive identification of only those animals from a given location that need to be investigated or treated.

[0012] The NAIS requires implementing a completely new governmentally-controlled system rather than utilizing existing systems currently in use. It also fails to make efficient use of infrastructure currently in place. Certain disclosed embodiments utilize known systems and infrastructure in various new combinations and in combinations with new methods and systems. Thus, many of the disclosed embodiments can be adopted without undue expense.

[0013] Some embodiments can potentially enable commercial economic benefits to industry from identification, tracking, management and process control to improve profits while protecting confidentiality and encouraging participation in the AIF. Overall, the disclosed embodiments may provide more accurate real-time identification, communication and recording of data for healthy animals and potentially problematic animals. This helps preclude a complete shut down of the food animal industry supply chain and helps prevent mistakes that impede normal animal commerce.

[0014] According to a first aspect, embodiments of the system and method described herein may allow health officials to implement a suitable strategy concerning animals that have commingled with a diseased animal in a manner sufficient to potentially transfer the disease, thereby reducing the chance that consumers will consume unhealthy or unsafe animal products. For example, if a cow is diagnosed with a disease, the tools and techniques of the disclosed AIF can be used to trace and ascertain the animal's location history. Based on that information, other animals that have commingled with or occupied a common location with the diseased animal can be examined, quarantined, slaughtered or otherwise treated for the same disease.

[0015] According to a second aspect, some embodiments of the system and method described herein may include collecting and organizing data in a secure framework that makes it possible to share official data and non-official data among the diverse and segmented portions of the livestock industries. Moreover, these tools and techniques make it possible for public and government entities to access official data by serving as a buffer between commercial animal information systems and government sponsored systems. For example, a filter tool may be used to screen non-official data from official data before releasing the official data to an official database or to a public or government entity.

[0016] According to a third aspect, some embodiments of the system and method include collecting, organizing, and storing information regarding the movement of animals. These techniques and tools have the potential to dramatically improve the ability of animal producers and other entities to trace an animal's movements and/or locations without releasing all animal data to a government-controlled system. Tools and techniques can be used to screen data from public and government entities. Upon request from a public or government entity, certain portions of the data may be released to allow health officials to identify and treat animals that have commingled with diseased animals in a manner appropriate for a particular disease. For example, when an animal is discovered with an animal disease, such as a foreign animal disease, health officials within the government may request access to the location history of the animal. Based on location identifiers, tools and techniques described herein can be used to generate a report listing animals that have commingled with the diseased animal. With that information, government and health officials can implement a strategy for minimizing the effects of the diseased animal on human health and commerce.

[0017] To implement the disclosed AIF, new and old technology can be combined. For example, some descriptions of potentially-useful technology appear in the documents listed below.

The system can include indicia elements associated with each animal for identifying the animal and a data entry device coupled to a computer for reading the indicia elements to identify the animal to the computer.

[0022] U.S. Pat. Nos. 5,573,002, 5,836,880, 6,200,210 and 6,579,236 disclose methods and apparatuses for measuring internal tissue characteristics in feed animals.

Some of the disclosed embodiments can be used, for example, to measure backfat and rib eye dimensions, obtain ultrasound images and determine rib eye area and marbling using measured tissue characteristics. This data can then be used to perform grading calculations, such as to determine quality and/or yield grades.

[0023] U.S. Pat. Nos. 5,673,647, 6,000,361, 6,135,055, 6,318,289, 6,516,746 and 6,805,075 disclose cattle management methods and systems. These patents are incorporated herein by reference.

[0025] U.S. patent application Ser. No. 11/292,412, discloses a method and system for determining the respiratory or circulatory health condition of animals for improved management. This patent application is incorporated herein by reference. Certain embodiments include imaging the internal organs, particularly the lungs, of animals and using information from this imaging to make management decisions regarding the animals.

[0026] Collectively, the above-referenced patents and application will be referred to herein as the “MicroBeef patent documents.” Certain embodiments of the Microbeef patent documents concern methods and systems implemented at feedlots or packing plants, for example. A person of ordinary skill in the art will recognize that the methods and systems can be implemented at other locations and integrated with the disclosed embodiments of the present invention.

[0027] Some embodiments of the disclosed method include entering into a computer system data relating to individual animals and correlating the data with an identification of the individual animals in the computer system. The data can, for example, be data for animals commingled from different locations. The identification of each animal can be entered into the computer system from a physical identifier for the animal enabling the computer system to identify each animal and distinguish it from every other animal in a group. The data entered into the computer system also can include location data for identified individual animals for a location or locations occupied by the identified animals. The location data can include, for example, location data generated by a GPS device. The location data for each animal can be correlated in the computer system with the animal identifications.

[0028] After the data has been entered, a user can be allowed to review a record for an identified animal that includes a location identifier for the present location of the animal and that the identified animal occupied a previous location without disclosing a previous location identifier. In some embodiments, the user is allowed to review a record for an identified animal that includes a location of the animal, a movement destination location of the animal, and that the animal occupied a previous location without disclosing the previous location identifier. For example, a seller of an identified animal may be allowed to review a record of the identified animal that includes a location identifier for the present location of the animal and that the animal occupied a previous location without disclosing the previous location identifier. The seller may then make available the identification and location data for the identified animal to a buyer. For example, the seller may provide information to a buyer to help the buyer make a purchase decision concerning the identified animal. Similarly, a buyer of an identified animal may be allowed to review a record of the identified animal that includes a location identifier for the seller location of the animal (and/or a location of the animal when owned by a seller) and that the animal occupied a previous location without disclosing the previous location identifier. A user also may be able to use the data in the computer system to identify a location or locations occupied by an initially identified animal. Then the user may be able to identify in the computer system a subsequently identified animal that shared a location with the initially identified animal.

[0029] Some embodiments further comprise entering into the computer system the identification of each animal from a physical identifier selected from the group of an RFID device, retinal scan, DNA profile, visual device, bar code device, brand, and combinations thereof. The RFID device may, for example, be an RFID ear tag, RFID implant, RFID bolus, or combinations thereof. The RFID device also may be recyclable. In some embodiments, multiple identifiers are entered into the computer system for the identified animal. The multiple identifiers can include, for example, an RFID device, a visual device and a DNA profile.

[0030] In some embodiments, confidential information can be filtered from data entered into the computer system to enable a user to review a filtered record. The confidential information can include, for example, a previous location identified for an identified animal. In these embodiments, the computer system may allow a user to determine from data in the computer system that an initially identified animal occupied a prior location or locations without disclosing a prior location identifier. Then, a subsequently identified animal can be identified that shared a location with the initially identified animal. For example, a user may be allowed to review a record for an identified animal that includes a location of the animal, a movement destination location of the animal, and that the animal occupied a previous location without disclosing the previous location identifier.

[0031] Embodiments of the disclosed method also can include transmitting data associated with an animal to the computer system comprising at least an animal identifier. The data can be transmitted, for example, from a physical identifier, such as an RFID device ear tag, a retinal scan, a DNA profiler, a visual device, a bar code device, a brand, or a combination thereof. The method also can include collecting the transmitted animal data in the computer system, wherein the animal data is correlated according to the animal identifier. The animal identifier can be associated with a set of previous location identifiers in the computer system, wherein the set of previous location identifiers is associated with a set of previous locations occupied by the animal. A current location identifier also can be associated with the animal identifier in the computer system, wherein the current location identifier uniquely identifies a current location of the animal. The system then may enable a report to be generated to list the current location of the animal and the set of previous locations occupied by the animal, wherein the set of previous location identifiers is filtered. The report may be generated, for example, based on the current location and previous locations occupied by the animal with the current location identifier filtered. A user then may be enabled to review the report. A subsequently identified animal may be identified that shared a location with an initially identified animal. This can be done, for example, by comparing the set of previous location identifiers to a set of location identifiers associated with the subsequently identified animal, correlating a subset of data from the animal data to a subset of data associated with the subsequently identified animal and filtering the set of previous location identifiers and the set of location identifiers associated with the subsequently identified animal. Some embodiments further comprise identifying in the computer system a second subsequently identified animal that shared at least one location with the first subsequently identified animal.

[0032] Embodiments of the disclosed system can include a physical identifier to transmit animal data, a data reader to read transmitted animal data from the physical identifier, a data service provider to store received data from the data reader, and a data trustee to receive at least a portion of the animal data from the data service provider and to filter confidential information from the received data. Some embodiments also include a GPS device for transmitting location data for an identified animal. The animal data can include, for example an animal identifier. In some embodiments, the data service provider adds to the animal data a premises identifier that corresponds to a location and the data service provider correlates the animal data according to the animal identification value. The premises identifier may be allocated by a premises allocator. The data trustee may reconcile the premises identifier against a premises identifier repository. Similarly, the data trustee may reconcile the animal identifier against an animal identification repository. In some embodiments, the data trustee maintains a database, such as a secured database.

[0033] The data trustee may generate a trace report based on the received animal data and may apply a filter to the received animal data to screen the confidential information. The trace report may, for example, list official data, such as locations that an animal has occupied without disclosing the premises identifier. The trace report may be accessible to be reviewed by users, such as buyers or sellers. The trace report also can be correctable. For example, some embodiments of the system include a web-based interface for correcting the trace report. The system also can include a public-accessible storage center to which the data trustee sends official data.

[0034] The data trustee may generate a variety of reports. For example, the data trustee may generate a report identifying in the computer system a subsequently identified animal that shared a location with an initially identified animal. The data trustee also may generate a confirmation report upon receipt of the received data.

[0035] Some additional embodiments are directed to controlling the spread of diseases, such as foreign animal diseases, such as mad cow disease. These embodiments may include requesting a trace report from a data trustee upon discovering a diseased animal, generating a trace report that filters confidential information and identifying location of animals that have commingled with the diseased animal. A treatment strategy then can be implemented for animals that have commingled with the diseased animal. The treatment strategy can comprise, for example, treating the disease, quarantining the animals, slaughtering the animals, or a combination thereof. Requesting a trace report from the data trustee can include determining an animal identifier for the diseased animal, performing a data look-up in a public sector database to retrieve a data record address that stores diseased animal data and retrieving the diseased animal data from the data trustee using the data record address. Generating the trace report can include performing a search on official and non-official data stored at the data trustee for location history data, wherein the search is performed using the animal identifier of the diseased animal, compiling the location history data for the diseased animal, comparing the location history data of the diseased animal to the other animals, generating a report of shared locations wherein the diseased animal commingled with others, and filtering non-official information from the report.

[0036] Some additional embodiments are directed to creating a buffer between commercial animal information systems and government sponsored animal systems. Such embodiments can include collecting animal data, distinguishing the animal data into official and non-official data, storing non-official data in a secure environment and implementing security procedures to protect the non-official data. Additional embodiments can include gathering location data for locations occupied by individual animals using RF triangulation or trilateration devices associated with the individual animals, entering or transmitting the location data into a computer system and correlating the location data with identifiers for the individual animal. The RF triangulation or trilateration devices can be GPS devices and may be integrated with physical identification devices associated with the individual animals.

[0037] Additional features and advantages of the invention will be made apparent from the following detailed description of implementations that proceeds with reference to the accompanying drawings.

[0130] Throughout this disclosure, the singular terms “a,” “an,” and “the” include plural referents unless the context clearly indicates otherwise. Similarly, the word “or” is intended to include “and” unless the context clearly indicates otherwise.

[0131] The following terms may be abbreviated in this disclosure as follows: Advanced Encryption Standard (AES), animal identification framework (AIF), bovine spongiform encephalopathy (BSE), Data Encryption Standard (DES), database management system (DBMS), electronic identification device (EID), Extensible Markup Language (XML), foreign animal disease (FAD), Freedom of Information Act (FOIA), group/lot identifier (GID), global positioning system (GPS), International Data Encryption Algorithm (IDEA), international organization for standardization (ISO), national animal identification system (NAIS), premises identifier (PID), pretty good privacy (PGP), radio frequency (RF), radio frequency identification (RFID), secure hypertext transfer protocol (HTTPS), Structured Query Language (SQL), United States Animal Identification Plan (USAIP), United States Department of Agriculture (USDA), and universal animal identifier (UAID).

[0132] Protecting animal agriculture by safeguarding animal health is vital to the well-being of people everywhere. In fact, protecting animal agriculture promotes human health, provides wholesome, reliable, and secure food resources, mitigates national economic threats, and enhances a sustainable environment. An element of this goal to safeguard animal health in an effective AIF that allows users to quickly and efficiently trace information concerning an animal, including without limitation, an animal's location history, treatment history, such as drug or feed additive administration, food products made from such animal, and any combination of such information. By doing so, diseased animals, those potentially diseased, and/or those animals that have commingled with the diseased animals may be identified and dealt with, e.g., treated, quarantined, or destroyed when necessary. Certain disclosed embodiments concern techniques and tools for implementing such an AIF.

[0133] The following provides definitions of certain terms used herein. These definitions are provided to aid the reader, and should not be construed to be narrower than would be understood by a person of ordinary skill in the art.

[0134] “Animal,” “animals” or “livestock” generally refer to any number of domesticated and/or wild animals such as swine, cattle, horses, bison, goats, sheep, deer, elk, alpaca, llama, poultry animals, fish, etc.

[0135] A “cohort” or “cohorts” refers to an animal or animals that occupied a same general location, such as might be identified by a premises identifier, as some other animal or animals, but not necessarily at the same time. Cohorts can refer to a group of animals occupying a same location, and if one or more of these animals is moved to a second location, then the moved animal now is, or animals are, associated with a second cohort group.

[0136] “Commingled” is a subset of the term cohort and generally refers to animals that occupy the same general location at a common time. For example, a first group of animals might be owned by the same owner and pastured separately from a second group. Both the first group and the second group may be referred to as cohorts, particularly if the first and second pasture are identified by the same premises identifier, but are not commingled. Animals in the first group are commingled, and animals in the second group are commingled, but animals of the first group are not commingled with animals of the second group. Commingling also can be considered to occur when animals have unrestrained access to each other. Under the USAIP, a single premises identifier may be used to identify cohorts, but cohorts may not be sufficiently intimately associated so as to warrant treating all animals in the group in the same manner, such as in case of a detected disease. By providing additional animal identifiers, as disclosed in the present application, cohorts in this and other examples can be treated differently.

[0137] “Feedlot” can include meat feedlots, dairy feedlots and any other animal feedlots.

[0138] “Food products” include, without limitation, meat, milk, poultry, eggs, fat and other animals products.

[0139] “Intimately associated” typically refers to animals that are in sufficiently close contact that, for example, transmission of a disease might be inferred. Simply because animals are commingled does not necessarily mean that they are intimately associated. Again by way of example, animals located in a large pasture area may be considered commingled, but may not ever be intimately associated.

[0140] “Participants” include, without limitation, producers, grazers, auctions, markets, feedlots, packers, data service providers, data trustees, and others.

I.) United States Animal Identification Plan (USAIP)

[0141] Over the last several years, animal industry professionals, academics, and state and federal government representatives have debated the feasibility of implementing a single, nationwide computerized system that utilizes an individual food animal identification tracking and management system. As a result of those debates, the United States Department of Agriculture (USDA) endorsed most of the USAIP that defines the standards and a framework for implementing and maintaining a phased-in national animal identification system (NAIS). Basically, the USAIP provides one proposed method to enable not only the beef industry but all livestock industries and government officials to perform lifetime traces and disease surveillance on cattle, swine, sheep, and other animals. Tracing animals would allow government officials, animal producers, animal purchasers, and others to determine where an animal has been and what other animals have been in contact with the “traced” animal.

[0142] For example, if a cow is diagnosed with mad cow disease, an NAIS would allow government health officials to trace where an animal has been over its entire lifetime and investigate and control the disease. Control can be achieved by any method deemed suitable at the time implemented, including, but not limited to quarantine, treatment or slaughter of animals that have commingled with the diseased animal. The USAIP requires that a complete trace report be obtainable within 48 hours of the initiation of an investigation following the diagnosis of a diseased animal.

[0143] The basics of the NAIS proposed under the USAIP are illustrated in FIG. 1. FIG. 1 shows the interaction between the NAIS 1002 and an animal producer 1102. The animal producer 1102 collects data 1112 about his animals and stores that data in a database 1202. The type of data collected by animal producer 1102 varies among animal industries; however, the data typically includes many of the same types of data that are found in a cattle specification. Under the USAIP, that data is supplemented by an official ID tag and may include additional identifiers to help trace a specific animal. For example, to trace an animal's location history, the USAIP proposes a premises identifier (PID) and a universal animal identifier (UAID) with the animal data 1112. Whenever an animal is moved to a new location, the new location's PID is linked to the animal's UAID in a database. By doing so, these identifiers help pinpoint where an animal has been during its lifetime.

[0144] Data collection usually begins at the animal producer's location. As an animal moves in the stream of commerce and passes through data collection points, additional records or information are collected and uploaded to a national animal information database 1302. The national animal information database 1302 receives a complete data record 1212. According to the USAIP, the national animal information database 1302 is accessible to the USDA and other health officials. Thus, when an animal is discovered with an animal disease, such as a FAD, the USDA determines the assigned UAID of the diseased animal and reviews the animal's records in the national animal information database 1302, which is also the “official database.” Based on recorded PIDs it is possible to generate a trace report 1222 showing where a diseased animal has been. At that point, appropriate measures can be put into effect to prevent those animals that have commingled with the diseased animal, as identified solely by a premises identifier, from entering the marketplace. The USAIP's goal is to protect people from buying tainted meats and other animal products and to prevent the disease from spreading to other animals.

[0145] To put an NAIS in place, the USAIP proposes implementing the following systems: a national premises identification system, an individual animal identification system, and a group/lot identification system.

[0146] A.) National Premises Identification System

[0147] The national premises identification system assigns a unique number to each premises involved in animal agriculture. Generally, a premises is an identifiable physical location that, in the judgment of animal health officials, area veterinarians, or other designated group, and, when appropriate, in consultation with the affected producer, represents a unique and describable geographic entity (e.g., where activity affecting the health and/or traceability of animals may occur) or represents the producer contact location when extensive grazing operations exist. By assigning a unique identifier to premises, the location history of animals is more easily tracked. The USAIP-proposed premises identifier is a 7-character alphanumerical value, e.g., A123B45.

[0148] FIG. 2 is a simple block diagram illustrating the USAIP's proposed infrastructure for assigning PIDs. Basically, a premises 2102 is required to file a request for a PID with a local government premises system 2202. The local government premises system 2202 contacts a national premises allocator 2302 for a PID 2112. The national premises allocator 2302 assigns a PID 2112 to the premises 2102 and sends it back to the local government premises system 2202. The local government premises system 2202 forwards it to the requesting premises 2102 and to a national premises repository 2402. The USDA has access to all PIDs through the national premises repository 2402. Using the PIDs, the USDA can determine animal location histories. According to the USAIP, the PID 2112 uniquely identifies a premises.

[0149] The USAIP's national premises identification system requires states and local governments to identify and validate premises.

[0150] B.) Individual Animal Identification System

[0151] In conjunction with a premises identifier, the USAIP proposes using an individual animal identification system involving assigning universal identification numbers (UAID) to tags, which are later associated with animals. FIG. 3 is a simple block diagram illustrating the entities involved in this process. The tag manufacturer 3102 first obtains a universal animal identification number (UAID) 3112 from an animal identification number allocator 3202 and manufacturers the tags 3502 with the UAIDs 3112 assigned to the tags. Typically, requests for tags come from animal producers. As illustrated, an animal producer at premises 3402 requests a tag from a tag manufacturer or distributor 3102. The tag 3502 is then forwarded to the requesting animal producer at the premises 3402. The UAID 3112 also is reported to a national animal identification number repository 3302 for the animal producer. Typically, the UAIDs 3112 adhere to the ISO code structure standard for radio frequency identification (RFID). The tag 3502 is attached to an animal and throughout the lifetime of the animal the tag 3502 is used to trace the animal's movements. In an exemplary UAID, according to the USAIP, the ISO code contains 15 numbers, for example, “840 123456789012.” This process creates a redundant database and tag tracking system adding cost and complexity to the system.

[0152] C.) Group/Lot Identification System

[0153] The USAIP also proposes a group/lot identification system, which assigns different values to specific lots or groups. For example, a large feedlot may have dozens of separate feeding areas. Each area or lot may receive its own unique number to further distinguish where an animal has been. Another reason for using a group/lot identification system is that animals often are transferred in groups to a premises or from a premises. Each shipment of animals that comes in or moves out may be considered a group. The GID is typically based on a date. For example, the USAIP requires that a six-digit number be added to the PID to reflect the date a group of animals moved into the premises. This means that an animal shipped to a premises with the PID “A234L69” on Oct. 3, 2003, has the combined group lot number “A234L69100303,” where the final six digits represent the date of arrival. The GID provides a way to further distinguish groups of animals of that have not been commingled. If a GID is used, the USAIP does not always require that each animal receive a UAID or a GID identifier on each animal. As discussed below, this may prevent reconciliation and confirmation from taking place to improve the accuracy of the data.

[0154] D.) USAIP Infrastructure

[0155] Based on the above-identified systems, the USAIP proposes an infrastructure that includes a national premises allocator, local government premises systems, a national premises repository, individual animal identification number databases, an animal identification number allocator, a national animal identifier repository and “reader” technology in order to trace animal location histories. The reader technology can include electronic RFID tags and RFID readers placed at various collection points. For example, the reader technology would be most likely implemented at markets, expositions, slaughter facilities, feedlots, etc. By recording the PID and UAID of animals, an accurate history of their movement through the streams of commerce can be recorded and traced.

[0156] Notably, within the USAIP, the identification devices used to identify animals may vary across species groups. Under the USAIP, the government assigns UAIDs, so official devices may be required.

II.) USAIP Deficiencies

[0157] Major opposition from the livestock industry has delayed implementation of the USAIP. One of the main drawbacks to implementing the USAIP's NAIS relates to the ability to protect the confidentiality of collected data. For example, many animal producers are concerned that the Freedom of Information Act (FOIA) would require the government to release all collected data. Releasing such information could cause irrevocable harm to the livestock industry just as it did when the first mad cow case was discovered in the U.S. Moreover, releasing confidential business information could also damage reputations and cause producers to lose money.

[0158] Protecting records also is important to prevent unfair speculation and manipulation of pricing at sourcing and markets. For example, if the government obtains and releases industry proprietary information, buyers or sellers of animals can artificially inflate or deflate prices based on the released data. Ultimately, collected data should be safeguarded. Hence, there is a need for a NAIS that ensures the confidentiality of that data.

[0159] The NAIS also has few, if any, aspects to verify the accuracy of data. Inaccuracies can be costly. For example, inaccurate tracking may result in treating, such as by quarantine, animals that were healthy and did not require segregation. This would cause a producer to lose money since quarantine interferes with the movement and management of animals in normal commerce. Moreover, because of an inappropriate quarantine, an animal producer and its herds generally may be perceived as being “bad,” which hurts the reputation of the producer and the value of its other herds. Furthermore, animal producers and marketers are concerned that they may incur consumer liability (or at least legal costs) due to inaccurate tracking results.

[0160] The USAIP's NAIS is difficult and costly to implement. The USAIP creates a separate NAIS dedicated exclusively to tracking animals. This means that animal producers that already use commercial systems to track their animals would have to finance their current tracking systems as well as the NAIS tracking system. Hence, the cost may become prohibitive, especially for small herd owners. Moreover, the USAIP experts failed to recognize the potential to utilize commercial tracking and management information systems that actually would add enough value to the process to cover the cost of complying with the official government requirements. Furthermore, the USAIP failed to recognize the inherent resistance to additional government mandated identification, reporting and costs to the industry when more then 99 percent of animals are healthy, disease free, non-quarantined animals. These additional costs would be incurred in order to identify the less than 1 percent of animals requiring FAD management.

[0161] The proposed NAIS regulates animal movement in commerce by requiring movement records. Moreover, the NAIS provides no method for a real time confirmation of the official records because it does not have access to confidential data by design. Real time confidential confirmation could be an important feature for buyers and sellers of animals. Again by way of example, a buyer may like to know, virtually immediately upon request, whether an animal has an appropriate movement record and, further, that such record can be accessed as desired. If such a record cannot be accessed by a buyer wanting to purchase an animal, then the buyer takes a risk that he will not be able to resell the animal. Thus, such information should be available to the buyer. The proposed NAIS does not allow or permit for real time confidential confirmation and reconciliation of such events, whereas some of the embodiments disclosed herein do allow for real time confidential confirmation and reconciliation.

[0162] The USAIP's NAIS also relies solely on RFID identifiers to identify an animal. A producer may lose an assigned RFID, or the RFID may fail to operate correctly. If this occurs, the animal's identification cannot be properly recorded, or if initially recorded correctly, cannot be verified upon a move-in or move-out event. RFIDs also would have to be requested by a producer according to an allocation by a government agency, associated with an individual animal, and then such information reported to the agency. This scenario requires time and compliance with the requirements by each producer as well as an additional inventory to keep. Embodiments of the disclosed method and system allow for these or other animal identifiers to be used and easily and accurately replaced, which simplifies appropriate identification of problematic animals and compliance by participants. Also, these embodiments can eliminate the risk of the tag allocation database confidentiality being compromised.

III.) Alternative to the USAIP

[0163] The components and systems of the disclosed animal identification framework (AIF) accomplish what the USAIP proposes, while overcoming one or more of its limitations. Some embodiments of the disclosed AIF incorporate computerized data management system tools and techniques to timely process information regarding the movement of animals from one location to another. These and other embodiments have the potential to help maintain the normal speed of commerce in buy/sell transactions, help provide records that make animals more valuable to buyers and sellers, improve the accuracy of animal movement and animal sales transactions, protect the animal owners from liability due to inaccuracies, protect the confidentiality of producer data, and lower the cost of tracking animals.

[0164] In commercial and official data settings, the information collected through the disclosed AIF can be beneficial in a variety of ways. For example, in some embodiments, when an animal change of possession occurs, the new owners or custodians are easily provided with the historical animal records and current records necessary to move the animal. Suppose, for example, a purchaser buys an animal without first obtaining a trace history of the animal. Owning animals purchased without records violates regulatory rules and purchasing animals without historical records incurs a risk of being unable to resell the animals. Some embodiments of the disclosed AIF avoid these problems.

[0165] Additionally, the disclosed AIF may protect purchasers against liability in case of a disease outbreak. Moreover, because information is collected in an organized and strong framework, it is possible to share commercial data among the diverse and segmented livestock industries, thereby adding value to the overall system, and helping offset the costs associated with the implementation of the AIF. There are many other private benefits and uses for the AIF, some of which will be described in the remainder of this disclosure.

[0166] In a public sense, the disclosed AIF is beneficial because it allows health officials to identify and quarantine animals that have commingled with diseased animals. Thus, it reduces the chance that a consumer will purchase infected meats or other tainted animal products. For example, if a cow is diagnosed with mad cow disease, to protect consumers from purchasing tainted meat, health officials or industry members, using the embodiments of the disclosed system and methods of the AIF, may trace and ascertain where the cow has been throughout its life. Based on that information, other animals that have commingled with the diseased cow can be examined or quarantined for the same disease.

[0167] To trace animals within the AIF, animal information can be recorded as the animals pass through data collection points. At minimum, the recorded information typically includes location history information (e.g., a PID) and an animal identifier. However, in many situations, animal information includes other information, including commercial and confidential information. For example, it may include the height, weight, size, age, sex, species, color, type of feed, drug treatment history, actual animal location, such as by GPS, name of owner, and other relevant animal information. Conducting a computerized trace of an animal typically involves ascertaining the animal identifier and searching the recorded animal information to find previous locations that the identified animal occupied.

[0168] Within the disclosed AIF are various tools and techniques for collecting animal information. The MicroBeef patent documents, the disclosures of which are incorporated herein by reference, describe various tools and techniques for collecting and tracking animal histories. For example, some of the tools and techniques described in the '647 patent, such as the electronic ID tag encoded with an animal identifier, may be used to uniquely and universally identify an animal. Such identifiers and tools in the MicroBeef patent documents may be used to collect and store animal information. For example, as an animal passes through data collection points, such as those described in the MicroBeef patent documents, animal information can be collected. Typically, the data collection points use sensors, scanners, or other reader technology to record animal information as the animal passes through a gate or chute. Additional information may be collected when an animal is examined, weighed, measured, or otherwise analyzed. With the collected information, authorized health officials and others may trace an animal's location history.

[0169] In some implementations, the AIF includes an integrated database system that shares official data among industry members and authorized health officials. The database system may be located, for example, at a single location, at multiple locations with identical, redundant information, or at multiple, networked locations sharing different information. The database system also may be in different countries to integrate information collected within multiple countries. In some embodiments, filtering tools and techniques are used to screen non-official data from any shared-access database. The shared information typically includes enough data for the USDA and health officials to accomplish their trace objectives, yet still protects animal producers' interests.

[0170] For example, the AIF can include a database specifically containing all reported animal records. This database can be administered and regulated by a data trustee, a data service provider or some other entity. The administrator can screen sensitive information from the government and other third-parties by filtering such information. The data trustee then only forwards to an official database the official data required to identify an animal and perform an animal trace. When a diseased animal is discovered, the USDA may enter an animal ID or premises ID to request a trace history for the animal from the official database. Such a trace history might include an indication that the animal occupied certain locations without providing specific location identifiers. Similarly, a trace report on a premises might include an indication that certain animals occupied the premises without providing specific animal identifiers. If required for a health-related trace, specific premises and animal identifiers can be provided to the government upon request. By implementing a data trustee function in the AIF and/or initially only allowing government access to a minimum amount of data, animal producers maintain control of most confidential information, and avoid many of the problems associated with inaccurate or leaked information. In some embodiments a data trustee is not utilized and the data trustee function is performed by the official database operator or another party.

[0171] The tools and techniques associated with the disclosed AIF use or adopt proven existing technologies wherever possible. For example, some implementations utilize state-of-the-art national and international animal identification standards with the best available practical technologies to create a plan that is dynamic and flexible. The AIF also can incorporate new and proven technologies as they become available. The techniques and tools described herein can be implemented in various ways, and may be used in combination or separately.

IV.) Animal Identification Framework Overview

[0172] The disclosed animal identification framework (AIF) can include an extensible framework designed to facilitate the collection and trace of animal data, including animal location histories. Within this framework, both hardware and software components can be included to, for example, identify animals, transmit data about the animals, collect the transmitted data, filter out confidential information from the collected data, and release the confidential data when necessary. FIG. 4 shows an exemplary AIF 4002 in which various techniques described herein may be implemented. Basically, the AIF 4002 has tools that collect and store (or work with hardware and software that collect and store) animal data, including animal identification data and animal location history data. The AIF 4002 filters non-official data and releases the official data upon proper request.

[0173] AIF 4002 is a cross-system framework that can be used with multiple database systems, hardware devices, and applications in many configurations. It provides a strong foundation upon which animal trace tools and techniques can be implemented. The AIF 4002 may use tools and techniques described in the MicroBeef patent documents, but this is not a requirement.

[0174] FIG. 4 shows various components of the AIF 4002. Among the illustrated components are a data service provider 4202 for receiving and storing mixed data 4112 from an animal producer 4102, a data trustee 4302 for screening non-official parts of the mixed data 4212 from the data service provider 4202, and an official database 4402 for storing official data 4312 forwarded by the data trustee 4302. Within the overall AIF 4002, there may be one or multiple data service providers 4202, data trustees 4302 and official databases 4402. The overall AIF 4002 is capable of collecting data from animal producers 4102, data service providers 4202, data trustees 4302 and others, and providing a trace report 4412 to the government 4502 and for authorized commercial uses.

[0175] The data service provider 4202 primarily is responsible for collecting the mixed data 4112. The data trustee 4302 primarily is responsible for screening the mixed data 4112 into official data and non-official data. The animal producer 4102, data service provider 4202 and data trustee may be the same entity or separate entities. For example, an animal producer 4102 may act as a data service provider 4202 and/or a data trustee 4302. Alternatively, the animal producer 4102 may be a separate entity, but the data service provider 4202 and the data trustee 4302 are the same entity.

[0176] A variety of tools and techniques may be used for collecting and transmitting animal information for use in embodiments of the disclosed AIF. These tools and techniques can be hardware-based, software-based or a combination thereof. For example, an electronic identification device (EID) may be attached to an animal. As the animal passes through an AIF data collection point, pre-encoded animal information may be collected from the EID. The data service provider 4202 may be used to receive and store this data.

[0177] Data service providers 4202 can include commercial data system organizations that have the necessary personnel, computer management expertise, and data gathering capabilities to detect, receive, store, and report animal information. Alternatively, or in conjunction with a commercial data system, a data service provider 4202 can include, without limitation, animal producers, marketers, and purchasers that own and operate the necessary reader and data storage technology to receive, store, and report animal information. Within the context of the disclosed AIF 4002, there may be a multitude, e.g., hundreds of data service providers 4202 to collect animal information. These data service providers may be ratified by industry members.

[0178] The mixed data 4112 received by the data service providers 4202 typically includes a mix of official and non-official data. Official data includes, for example, the data necessary for the government 4502 to trace an animal. Non-official data generally is all data other than official data. Non-official data can include, for example, commercial data, such as animal age, weight, sex, etc. Both official data and non-official data may be confidential. In some embodiments, the data service provider 4202 forwards only official data to the data trustee 4302. Alternatively, the data service provider 4202 may forward both official and non-official data to data trustee 4302. If there is no data trustee 4302, the data service provider 4202 may screen the mixed data 4112 and forward official data the official database 4402 or directly to the government 4502.

[0179] Within the AIF 4002, the data trustee 4302, if present, can act as a buffer between commercial animal identification systems and any government system. The functions of a data trustee 4302 can be to receive forwarded data 4212 from data service providers 4202 or animal producers 4102, to screen and filter the forwarded data 4212, to maintain the official database 4402, which may be a multiple-database system, and to generate reports.

[0180] As a component within the AIF 4002, a data trustee 4302 can include those individuals, groups, organizations, and tools designated by industry members, perhaps approved by the government, to screen the forwarded data 4212 before it is sent to the official database 4402, which is accessible by the government 4502. The actual number of data trustees 4302 may vary based on cost to implement, size and growth of animal industries, improving network and database technologies, and other such factors. As mentioned above, in some embodiments, the data service provider 4202 may act as its own data trustee 4202.

[0181] As shown in FIG. 4, after receiving data 4212, the data trustee 4302 may screen and filter the data to remove non-official data. The data trustee 4302 then forwards official data 4312 to the official database 4402. Typically, the official data 4312 includes the necessary information for the government 4502 to start tracing an animal's location history. For example, the data trustee 4302 may filter all the data it receives except for an animal identifier and a data record address to a record in the official database 4402. Thus, knowing the animal identifier may be sufficient to retrieve the other animal information from the official database 4402. In other implementations, the data trustee 4302 may filter more or less data. For example, if the government 4502 requests a trace report 4412 based on a premises rather than a specific animal, the data trustee 4302 may forward a premises identifier and a data record address from the official database 4402 for each animal associated with the premises identifier. The amount and type of data forwarded to the official database 4402 may change as government and industry needs change.

[0182] The official database 4402 can serve as a repository of official data 4412 from the data trustee 4402. In the disclosed AIF, a data trustee 4302 can be the administrator and arbiter of all the official data 4312 that is stored in the official database 4402. In some implementations, the official database 4402 is the only database to which the government 4502 has access. In other implementations, the data trustee 4302 is the only entity to have access to the official database 4402. More than one official database 4402 may be maintained in order to provide more rapid access to official data 4312 and to provide redundancy and fail-safes in case a connection or system goes down. Data in multiple databases can be synchronized periodically to ensure consistency throughout the databases.

[0183] In some implementations, the data trustee 4302 maintains the official database 4402 and the government 4502 maintain a separate database. In addition, a separate database may be maintained under the control of the data trustees 4302 and used to contain non-official data. This allows industry members to keep some data confidential until requested by the government 4502. For example, if a rancher wants to keep his ranch premises identifier confidential, some embodiments of the disclosed AIF 4002 would make it possible to do so. The government 4502 does not actually need access to the premises identifier until an animal health or safety issue arises. Thus, the data trustee 4302 can filter the premises identifier from being forwarded to a database accessible to the government 4502, e.g., the official database 4402. When the need arises, the government 4502 may submit a request to the data trustee 4302 for premises identifiers. After a proper request, the data trustee 4302 may send the requested information to the government 4502. The number of filtered fields in the official database 4402 may vary depending on implementation, government regulations, logistical concerns, ease of implementation, and other such factors.

[0184] Using data requested from the official database 4402, the government 4502 typically has access to sufficient data to trace an animal within the currently mandated 48-hour time period. In other implementations, tracing an animal may take more or less time to complete, and much faster trace results likely can be achieved with the present method and system, such as within minutes.

[0185] In the embodiment illustrated in FIG. 4, the AIF 4002 provides a variety of trace reports 4122, 4222, 4322, 4422 to confirm events as they occur. Trace reports can take several forms. For example, some trace reports include all location data for an animal. Confirmation reports, which are a type of trace report, typically include enough data to confirm some event, such as a move-in or move-out event, and may protect the confidentiality of premises identifiers while providing a function important to animal commerce. Another type of trace report, the reconciliation report, can be generated to reconcile a discrepancy in reported data. Reconciliation reports typically are generated upon request when the data, such as the data in a confirmation report indicates a discrepancy. For example, when an animal is shipped to a feedlot, a confirmation report 4122 can be sent to the animal producer 4102 confirming animal arrival. Similarly, when data 4212 is forwarded to the data trustee 4302, a confirmation report 4222 can be sent confirming receipt of the data. After the data 4212 has been filtered and official data 4312 forwarded to the official database 4402, another confirmation report 4322 can be generated and sent to the data service provider 4202 and/or the data trustee 4302 confirming receipt of the information. If a discrepancy is found, such as between the official data 4312 and data stored in national identifier repositories, a reconciliation report can be generated. The format and delivery methods of these reports may vary. For example, some reports can be sent via text email. Other reports can be accessed over a webpage. In addition, some reports can be sent as text files, PDFs, or other standardized format. Alternatively, the reports can be sent as text messages, paper copies, or some other readable format.

[0186] In some other implementations, animal producers 4102 are allowed to request a reconciliation report from the data trustee 4302 in order to view their current inventory as recorded in the official database 4402. This function allows producers 4102, data service providers 4202, and data trustees 4302 to correct any potential database errors by reconciling information. For example, upon request, a rancher may file a move-out report with a data service provider 4202 and receive a move-in report from the data service provider 4202. The rancher may check the reports against each other. If there are any errors, the rancher may submit a request to correct the information. By generating confirmation reports as data passes from one component of the AIF 4002 to another, errors and inconsistencies in the data can be identified throughout the process, avoiding major discrepancies or errors in the future. Confirmation reports also provide an automated chain of custody to ensure the database information is synchronized with actual animal movements. Without a chain of custody and reconciliation process the system may become less reliable and animal producers 4102 may experience greater liability.

[0187] In some embodiments of the AIF, non-government entities that request trace reports are screened to ensure that they are authorized to receive the data. For example, an animal producer 4102 may request a reconciliation report for his own animals, but may not request a reconciliation report for the animals of another producer. The AIF can include password-protected access and other security features to verify the identify of requesters.

[0188] In some embodiments, the data trustee 4302 and the official database 4402 allow animal producers 4102 or other users to perform the essential functions of reading, updating, and deleting records. To do so, an interface, such as a web-based interface, a database interface, or customized software application, can be provided so animal producers 4102 or others may securely connect to the database to read and/or update records. In some implementations, error correction is done directly by the animal producers 4102, e.g. they log onto a secure system and manually correct errors. Preferably, an animal producer 4102 submits a request to correct erroneous data to the data trustee 4302. The data trustee 4302 verifies the submitted data and makes appropriate updates. Other techniques for updating and correcting information also may be available.

[0189] As shown in FIG. 4, within the AIF 4002, the government 4502 can trace animal location histories. For example, the government 4502 may request data from the official database 4402 and then may submit an additional request for a complete trace of an animal to the data trustee 4302. Upon receipt of a request, the data trustee 4302 generates a trace report 4412 from the official database 4402. The trace report 4412 can include a list of every premises the animal has occupied during its traceable lifetime. The trace report 4412 also can include other information, such as the date, time, and group number associated with an animal when it lived at a premises.

[0190] Using the information from the trace report 4412, the government 4502 may contact the listed premises for more information or request further information from the data trustee 4302. In some implementations, the initial trace report 4412 includes identifiers for all animals that have ever commingled with the traced animal.

[0191] Notably, when the government 4502 makes a direct request to the data trustee 4302 for information, all official data is granted within the guidelines set forth by government and industry regulatory bodies. Other information is released at the discretion of the data trustee 4302.

[0192] The disclosed AIF 4002 includes elements of software and/or hardware. The relationship shown between the components in FIG. 4 is one example of the main flow of information; other relationships are not shown for the sake of simplicity. Depending on the implementation, components can be added, omitted, split into multiple components, combined with other components, and/or replaced with like components or systems. Alternatively, a framework with different components and/or other configurations can be used to perform one or more of the AIF processes described herein.

[0193] Various implementations of the components in the disclosed AIF are described in greater detail in the following subsections.

[0194] A.) Data Service Provider

[0195] Data service providers typically provide the necessary data collection tools, reporting systems and services, customer support and education to enable the transfer of data from animal producers to data trustees. FIG. 5 illustrates a simple block diagram of a data service provider 5002. The data service provider 5002 collects and stores animal information in a single or multiple data service provider databases 5502, generates reports 5552 confirming receipt of the information, and then forwards official data 5602 to a data trustee. As illustrated in FIG. 5, the data service provider 5002 includes elements of software and/or hardware. The relationships shown between the components in FIG. 5 indicate the main flow of information; other relationships are not shown for the sake of simplicity. Depending on implementation, components can be added, omitted, split into multiple components, combined with other components, and/or replaced with like components or systems. Alternatively, a data service provider with different components and/or other configurations perform one or more of the techniques described herein.

[0196] 1.) Animal Information Sources

[0197] The data service provider 5002 can receive data from multiple sources. The data service provider 5002 also may receive a variety of different types of data. As shown in FIG. 5, these types of data may include animal identification data 5102, commercial data 5202 and premises identification data 5302.

[0198] a.) Animal Identification Data

[0199] The animal identification data 5152 is data that is unique to an individual animal. All of the data collected for an animal, including premises identifiers and commercial data can be linked to the animal's identification data 5152. Thus, the animal identification data 5152 can serve as the data that distinguishes one animal's record from another animal's record.

[0200] As discussed above in connection with FIG. 3, the animal identification data 5152 can include an assigned UAID. Under the USAIP, the only form of identification for an animal is its UAID. This approach, however, can be problematic if, for example, an animal loses its tag. Under the USAIP, a new tag would have to be assigned along with a new UAID. Assignment of a new UAID for the same animal is likely to cause errors in the database and may compromise the confidentiality of animal data. In some embodiments of the disclosed AIF, the animal identification data 5152 includes more than one identifier. For example, the animal identification data 5152 can include a database identifier to which the other animal identification data 5152 is correlated. Thus, if an animal's tag is lost, the animal can be assigned a new tag associated with a new number correlated in the database to the same database identifier. This prevents errors in the data. Additional animal identification data 5152 can include, for example, data from RFID devices, retinal scan data, DNA profiles, data from visual devices, data from bar code devices, data from brands, and combinations thereof.

[0201] In some embodiments, the database identifier is the UAID. For example, an animal may receive a tag with a UAID assigned by a government animal identification allocator. When the tag is associated with an animal, the UAID is entered into the database and becomes the permanent database identifier for the animal. If the animal subsequently loses its tag, a new tag can be associated with the animal and the number on the new tag can be linked to the animal's database identifier (which is the UAID from the first tag assigned to the animal). Thus, unlike under the USAIP, the UAID can remain a permanent identifier for a particular animal even if the animal loses its tag.

[0202] UAIDs are proposed under the USAIP as official 15-digit-ISO identification numbers allocated by the USDA. As discussed above, these numbers may be encoded on an RF tag or other device. However, in some cases, at the producer's option, the official numbers are not required to be associated with the animals and alternate physical identifiers are used. For example, in a small herd of 20 animals, the animal producer may keep a list of his animals' UAIDs. When an animal identified by an identification device is moved or sold, animal information, including tracking information, may be scanned from the producer's records (e.g., scanning bar codes from paper), entered manually, or input in some other way.

[0203] The database identifier also can be a value other than the UAID. If the official database is accessible to the government, having a database identifier other than the UAID, which typically is assigned by the government, helps to protect the confidentiality of the data. For example, the accessible data may show that certain animal identifiers are associated with a premises identifier without actually identifying the animals.

[0204] Some assigned animal identifiers, such as UAIDs, can be placed in an animal identifier repository. This repository may serve to ensure the uniqueness and universality of the animal identifiers and to ensure that animal data is available for access when needed. In some implementations, an animal identifier allocator assigns animal identifiers to tag manufacturers. Under the NAIS proposed in the USAIP, as new animals are born, a rancher may request tags for each newborn animal. Each tag has an encoded animal identifier that originated with the animal identifier allocator. Under the USAIP, the animal identifiers are UAIDs that also serve as database identifiers. In some embodiments of the disclosed AIF, multiple identifiers can be used. For example, the multiple animal identifiers may be associated with a single database identifier so that if a tag is lost, the number identifying the animal in the database does not need to be changed. In some embodiments, identifiers are encoded onto tags by tag manufacturers without giving the government access to the identifiers. This further protects the confidentiality of the data.

[0205] Some forms of animal identification data 5152 provided to the data service provider 5002 via a physical device, such as a tag. The device can include elements of software and/or hardware. Various implementations of identification devices are discussed in the MicroBeef patent documents, which are incorporated by reference. For example, in the '647 patent, an identification tag that uses radio frequency technology (RFID) to transmit signals to an RF reader is disclosed. The RF reader collects and stores the data sent by the tag. In other implementations, the identification device may use other wireless and/or microwave technologies, such as Wi-Fi, WiMax, etc., to transmit animal information to the data service provider 5002. Moreover, in yet other implementations, the identification device is a transponder, a chipcard, a biometric device, a magnetic device, a scan code, a bar code, a visual cue such as a cattle brand, or any other state-of-the-art and/or cost effective technology. Alternatively, the device is implemented as a combination of these technologies.

[0206] Under the USAIP, a specific type and design of radio frequency identification (RFID) tags are used as the official identification device to identify animals. However, any RFID tags following ISO standards can create numbers that universally identify animals without needing any additional setup. The USAIP numbering system provides producers the flexibility to utilize readily available ISO compliant identification devices from a source of their choice. For example, there are nonofficial RFID ISO compliant tags that may be used one time or multiple times to reduce the cost. Recycling the RFID tags is particularly useful if the tags include GPS functionality, which makes them more expensive to replace. Moreover, by using non-official, ISO compliant tags the industry is not burdened with sourcing restrictions and managing official tags inventory for the USDA. Furthermore, different species of animals may use different types of tags.

[0207] In some implementations, the identification devices are programmable, e.g., animal producers or others can encode information onto the devices. At the very least, the devices include an animal identifier to uniquely identify an animal. However, other information, including but not limited to, age, sex, weight, breed and/or species, owner, drug history, feed history, and combinations thereof also may be encoded into the device.

[0208] Animals other than food animals also can be tracked by the system, as they also may come into sufficiently close contact with a food animal to transmit disease. For example, pets and wild animals that are tracked by pet owners or wildlife officials also can be tracked using disclosed embodiments of the method and system.

[0209] As an animal identification system, either a nationwide (NAIS) or worldwide system, is implemented, there may be difficulties in assimilating and converting current tracking systems. To reduce costs, to allow producers and data service providers to maintain their current systems while the transition occurs, and to allow time to install approved tags on animals, animal information may be linked to other values until a permanent system is in place. For example, the name of a company and its proprietary animal identifier may uniquely identify an animal. Thus, during the transition phase, an additional field in the various databases lists that temporary identifier value, until a new conforming identifier is in place. Animal information is updated and linked to the new animal identifier as it becomes available.

[0210] In some implementations, the animal identifier is associated with meat shipments during processing and even after the animal has been slaughtered. For example, packaging containing processed food products can be tracked, and the food products correlated with the animal history from which such products were produced.

[0211] b.) Commercial Data Sources

[0212] Referring again to FIG. 5, the data service provider 5002 also may receive and store commercial data 5202 from commercial data sources. Commercial data 5202 can include commercially valuable data, e.g., the type of data used by animal producers in the course of business. Commercially valuable information can include, but may not be limited to, an animal's owner, breed, size, weight, age, sex, feed type, vaccination or other treatment reports, pricing terms, veterinarian reports, and any other data that is commercially useful. The amount and type of commercial data 5202 collected by the commercial data sources may vary based on individual producer needs. Commercial data 5202 sent by commercial data sources can be collected by the data reader 5402. In some embodiments, all inputs into animals is tracked. For example, the identifications and locations of feed can be tracked and associated with the animals that consume the feed. Computerized systems for manufacturing and/or administering feed may facilitate this form of tracking.

[0213] The age of an animal can be determined, for example, by dentition. An animal's age can be evaluated based on its teeth by any known method, such as visual inspection, video imaging of the mouth with manual or automated analysis of the images and any combination thereof. Age also can be determined by ultrasound examination of animal bones or by DNA profile.

[0214] In some implementations, commercial data sources 5402 are the tools and techniques described in the MicroBeef patent documents, which are incorporated herein by reference. For example, one aspect of the '647 patent tracks the historical and projected weights of animals using external measurement tools at feedyards. That information may be valuable for commercial purposes. Using such tools and techniques described in the '647 patent, information can be collected and transferred to the data service provider 5002. The actual transfer can involve transmitting information from the animal producer's computer systems to the data service provider 5002. The data reader 5402 receives the commercial data about an animal and adds it to the animal's complete data record 5452.

[0215] c.) Premises Identification Data

[0216] A premises identifier 5302 identifies a premises, which is an identifiable physical location where an animal might be located. In FIG. 4, premises typically include animal producers 4102, processors and markets. Referring again to FIG. 5, the premises identifier 5302 can be submitted by the participant and automatically added to animal data records by the data trustee whenever an animal is moved from one premises to another. The data trustee may first validate the premises identifier for the location. For example, if a cattle rancher auctions an animal locally, when the animal moves from the ranch to the auction house the animal's data records can be updated to reflect this move by, for example, submitting a move report to a data service provider 5002. When the animal arrives at the auction house, a new data entry, including the auction house's premises identifier, is added to the animal's records showing the animal's arrival. This new data entry is submitted to the data service provider 5002. An animal's location history can be tracked using the animal identifier 5152 to obtain the premises identifiers 5302 for locations occupied by the animal. In some implementations, the premises identifier 5302 is the PID described above in connection with the USAIP. Alternatively, the premises identifier 5302 is a different value.

[0217] In some disclosed embodiments, animal movements are tracked during transport from one premises to another. For example, animals commingled on a single transport, such as a truck or train, might be identified. GPS may be used for tracking vehicles transporting animals as an additional method for tracking movement and location of the animals. The use of GPS for tracking vehicles transporting animals can be accomplished with systems similar or identical to existing systems for tracking trucks, ambulances and other vehicles. Typically, a GPS receiver and associated data storage device are used to record the vehicle's coordinate location. The location data can be stored for future transmission or may be transmitted to a data storage location in real time using RF communications or other methods. GPS mapping products, which are readily available commercially, can be used to transform GPS coordinate location data into illustrative mapping. The loading and unloading locations of transport vehicles are readily determined by recording GPS coordinate data as well. Furthermore, the identification of animals by RFID or other methods at loading and unloading locations or on the vehicles can be accomplished with conventional RFID readers or other devices. Such data can be recorded for integration with the GPS coordinate data in a computer system.

[0218] As suggested by the USAIP, in some implementations a national or worldwide premises allocator assigns PIDs upon request. Referring back to FIG. 2, however, there are other implementations for allocating premises identifiers not described by the USAIP. For example, an animal producer may fill out on electronic request form and submit it to the premises allocator 2302 via the Internet. In response, the premises allocator 2302 would assign and send a PID 2112 to the requesting animal producer. Notably, in this implementation, the premises allocator 2302 assigns the PID 2112 without prior screening by state officials. In other implementations, the premises allocator 2302 files a request with the state for verification information before assigning the PID 2112. Alternatively, the premises allocator 2302 verifies some minimal pieces of data, such as name, address, and phone number, before allocating the PID.

[0219] Another implementation for assigning premises identifiers involves the data trustee. The data trustee can be given a range of premises identifiers that are allocated when an animal producer or premises reports animal information for the first time. For example, when a non-registered premises sends animal information to a data service provider, since there is no valid premises identifier, the information can be immediately forwarded to a data trustee. The data trustee then obtains and allocates a premises identifier for the non-registered premises and notifies the premises of the new value. Moreover, a copy of the premises identifier with accompanying premises identification information can be deposited in a national premises identification repository. As before, the data trustee may ask for verification information from the requesting premises before allocating a premises identifier.

[0220] In some cases, the premises allocator or data trustee assigns a temporary identifier to a premises until the premises can be certified by either the allocator, government agency, or the data trustee. Under these circumstances, the temporary identifier may be only allocated for a short period of time, after which the premises needs to be authenticated by an appropriate entity.

[0221] If a temporary identifier is used, after a premises is authenticated the temporary identifier can be made permanent. Alternatively, a new permanent identifier can be assigned and all records with the temporary identifier can be updated with or linked to the new identifier. Again in the alternative, records received from a premises with a temporary identifier can be maintained in a separate database until the premises has been authenticated. At that point, all of its records can be moved to a valid premises database. Temporary identifiers may be distinguished from permanent ones based on their format, based in a table listing temporary identifiers, or in some other way.

[0222] The actual format of the premises identifier may vary. According to the USAIP, a PID is a 7 character alphanumeric value. In other implementations, the premises identifier may have more or fewer characters. Moreover, a premises identifier may be randomly generated according to a defined format, it may be assigned from a master list or database of values, it may be derived from animal producer information (e.g., a hash of the premises' name or other proprietary information), it may incorporate letters or numbers from a premises company name or brand, or it may be derived in some other way.

[0223] In some implementations, a value such as a NULL, zero, or other random non-conforming value may be inserted into a data record until a proper premises identifier is received.

[0224] Animal producers and premises can be notified of their new premises identifier via a receipt web page, an email, mail, telephone call, or some other mechanism. In every case, the newly-generated PID is sent to a national or worldwide premises repository, such as the repository 2302 described in connection with FIG. 2.

[0225] Referring again to FIG. 5, once a premises identifier 5302 has been assigned and sent to the proper premises, the premises should include the premises identifier 5302 anytime it sends data to a data service provider 5002 or to a data trustee.

[0226] It is worth noting that, although the premises allocator is described herein as a single entity, implementations may include more than one allocator, each designated by government and industry members.

[0227] In some embodiments, an animal's identification device or a separate device associated with an animal can be used to provide specific location information. Specific location information is more descriptive of an animal's location than general location information, such as premises identifiers 5302. For example, a specific location device can include circuitry to receive an RF signal from three or more reference points (e.g., three or more GPS satellites). The received signals then can be used to calculate a location using conventional triangulation or trilateration techniques. The locations occupied by an animal at various times (e.g., at certain time intervals) can be stored in the device and uploaded or otherwise entered into a computer system when the device is read. Alternatively, the location information can be transmitted to a database separate from the device, from which it can be sent to a data service provider 5002. As another option, the location information can be read by an operator who travels to an animal location. The location information gathered by the operator can be, for example, entered into a handheld computer and then uploaded into the data service provider database 5502.

[0228] Devices for receiving reference signals and calculating specific locations can be powered, for example, by batteries and/or solar power. Examples of commercially available GPS devices that may be adapted for use on animals include vehicle tracking devices, such as S-911 available from Laipac Tech Inc. (Ontario, Canada) and pet tracking devices, such as the GLOBAL PET FINDER available from GPS Tracks LLC (Jericho, N.Y.).

[0229] Generating data on the specific locations of animals at specific times without the need to move the animals to a scanning location has many advantages. For example, this process makes it possible to track animals being transported between premises with assigned PIDs. The process also allows the locations of animals at pasture to be tracked. The specificity provides for the highly accurate identification of animals that have and have not been in close contact with a diseased animal. When a diseased animal is discovered, the exact locations occupied by the animal can be determined and compared to the locations occupied by other animals, such as other animals at the same premises. If there is no overlap in the location data, it can be assumed that the other animals were never in intimate contact with the diseased animal and thus are not likely to have acquired the disease. Thus, the process reduces the wasteful treatment, quarantine and slaughter of animals that are commingled with a diseased animal, but never have sufficient contact with the diseased animal to acquire the disease.

[0230] d.) Group/Lot Identifiers

[0231] Related to premises identifiers are group identifiers (GIDs), which distinguish groups of animals from each others as they move through a premises as noted in connection with the USAIP. According to the USAIP, a GID is a six-digit identifier representing a premises arrival date and in some cases is combined with the premises identifier. Thus, unlike the premises identifiers, GIDs are generated by the participant or data service provider, and they may not necessarily be unique. For example, all the cattle that arrive at a feedlot on a specific date may be assigned the same GID. Alternatively, a GID may represent other information, for example, the building where an animal was housed. The GID may be combined with the PID to form a new identifier, or alternatively it may be a separate value in the mixed data database. An alternate embodiment may include using the GID on each animal in a group or lot.

[0232] 2.) Data Reader

[0233] FIG. 5 shows a data reader 5402, which collects animal information for the data service provider 5002. The data reader 5402 can include elements of software and/or hardware. Various implementations of data readers 5402 are discussed in the MicroBeef patent documents, which are incorporated by reference. For example, the '647 patent describes computer systems that record, measure, sort, and track individual animals. The data reader 5402 described herein may perform the same and/or additional functions.

[0234] In some implementations, the data reader 5402 collects wireless and microwave technology transmissions (e.g., RFID transmissions) from devices directly attached to animals. Moreover, the data reader 5402 may collect signals and data from transponder devices, chipcards, biometric devices, magnetic devices, GPS devices, and other devices attached to or implanted into an animal. Alternatively, the data reader 5402 receives data transmissions from computing devices, such as computers, PDAs, scanners, cell phones, flash memory cards, and other similar electronic devices containing data, such as commercial data. In yet other implementations, the data reader 5402 uses video imaging and/or ultrasound technology to gather data. In other implementations, light or laser technology is used to scan bar codes or other visual cues (e.g., a cattle brand or mark). In some embodiments, animal information is read manually (e.g., visually) and input manually (e.g., through data entry or voice recognition means). Alternatively, other state-of-the-art and/or cost effective data reader technology is used. The data reader 5402 also can be an optical character reader. Such a reader also may serve as a barcode reader or reader of some other form of visual device.

[0235] Data readers 5402 can be installed at designated reader locations. For example, since participants include producers, grazers, auctioneers, feedlots, packers, and other animal marketers, data readers 5402 can be installed at their premises by themselves or with a data service provider 5002. When an animal is sent to a participant that includes a data service provider 5002, the animal typically passes through an entrance gate or chute. An exemplary data reader 5402 is installed at the entrance of the gate or chute. Alternatively, the data reader 5402 is installed in animal barns, pens, stalls, or other similar locations.

[0236] As an animal passes through the data reader 5402, the data reader collects animal information. At minimum, this includes an animal identifier 5152. Other commercial and official data also may be collected at this time. The other data also can be transmitted separately, e.g., via a computer disk, a paper copy, an email, a computer file, etc., and later correlated to the animal identifier 5152 in the data service provider database 5502.

[0237] Data collection systems are not limited to any location and can use multiple systems and multiple databases to collect, store, report out and report back data to submitters.

[0238] 3.) Data Service Provider Database

[0239] After the data reader 5402 collects information from the animal information sources, the data can be added to the data service provider database 5502 as a mixed data record 5452. A mixed data record 5452 combines non-official data with official data, typically in a single entry, in the data service provider database 5502. Other animal information, such as premises identifiers 5302, may be added automatically by the data service provider 5002. In some implementations, the data service provider database 5502 is indexed by the animal identifier 5152.

[0240] The data service provider database 5502 can be built from commercially available database services. For example, the data service provider database 5502 can be an SQL database with various fields, such as breed, weight, date and time of arrival, animal identifier, premises identifier, etc., defined for the types of information received from the data reader 5402. Alternatively, a different database builder is used, e.g., an XML database, an Access database, a web-enabled database, or any other well-known database management system (DBMS). In other implementations, a custom database is developed.

[0241] For ease of administration, the data service provider database 5502 may be spread over multiple computer systems. For example, a feed lot may serve as a data service provider 5002 that receives data for thousands of animals every day. Due to the volume of the information being collected, multiple portions of the data service provider database 5502 may be distributed across many different computer systems and perhaps even multiple computer networks in order to handle the information. To maintain consistency throughout the separate portions of the data service provider database 5502 and to keep the information current, the database portions can be synchronized periodically.

[0242] Defined fields can be filled as animal information is collected into the mixed data record 5452. Typically, not every field needs to be filled to be complete the mixed data record 5452. A complete animal record may include a subset of the information in the data service provider database 5502, such as the animal identifier 5152, premises identifier 5302, event type and date and time of arrival.

[0243] At least some of the data stored in the data service provider database 5502 can be forwarded to the data trustee. Alternatively, the data service provider may act as its own data trustee. In such embodiments, the data service provider may screen the mixed data into official data and non-official data and forward the official data to the official database or the government.

[0244] 4.) Reports

[0245] The data service provider 5002 can provide various reports, such as the reports 5552 sent to producers and data trustees confirming that the data has been received, recorded, meets NAIS standards, etc. These reports 5552 can provide information regarding the status of an animal event and also can provide a chain of custody that shows where an animal has been. Exemplary animal events include having an identification device applied, moving from one location to another, branding, sightings, shipment to a slaughterhouse, processing into food products, shipping as food products, etc.

[0246] When a move-out transaction from one premises to another has been initiated, then a corresponding move-in (receipt) transaction typically needs to issue to acknowledge that the animals, or food products made therefrom, arrived at a valid premises within a specified time period. For example, if a rancher sends an animal to a commercial feedlot (in this case serving as a data service provider 5002) before sending it to be slaughtered, moving the animal from one location to another can be recorded by data readers 5402. A data reader 5402 at the ranch can be used to record when the animal leaves and, in addition to other information, a data reader at the feedlot can be used to record when the animal arrives. Upon arrival at the feedlot, a confirmation report can be generated notifying the rancher that the animal arrived. This report typically includes the animal identifier 5152, premises identifier 5302, and the event being confirmed. Alternatively, it includes a complete report of all recorded animal information, or any combination of sortable recorded information.

[0247] The reports 5552 also can be used to verify that data has been accurately recorded and to reconcile data with other databases. In the example above, a rancher may determine from the confirmation report that an animal's listed information is incorrect. To correct the error, the rancher may contact the data service provider 5002 and provide it with the correct data. In the above example, if the commercial feedlot, as part of a normal verification process, checks with the repository or data service provider 5002 to validate the rancher's premises identifier, it also may detect the error. If the error is detected, a reconciliation report detailing the error can be generated and sent to the commercial feedlot and to the rancher. Again the rancher corrects the error, even if it means requesting a valid premises identifier 5302.

[0248] The number and type of reports 5552 generated by the data service provider 5002 may vary, depending on, for example, government and industry regulations, animal producer and data service provider 5002 wants and needs, and other such factors. Exemplary reports include a move-out report, a ship and trace report, a move-in and reconcile report, and a termination report.

[0249] FIGS. 6A-6D show sample reports generated by a data service provider 5002. For example, FIG. 6A shows a sample move-out confirmation report. The report confirms that 38 animals were shipped from a premises with PID S200971 and all the animals arrived at the destination premises (premises F201565).

[0250] FIG. 6B shows a sample move-in report. This report notifies the animal producer that seven of his animals are unaccounted for. The animal producer can then follow-up with the data service provider 5002 to reconcile this discrepancy. For example, the animal producer may wish to order a reconciliation report, which would have data from before the move-in event and from after the move-in event for comparison. Reasons for this type of error include the fact that the animals may never have arrived at the destination premises, the premises identifiers 5302 may be unknown or unregistered, the animal identifiers 5152 may be invalid, or there may have been a hardware or software failure. Whatever the reason, the animal producer should know that he needs to check on his animals.

[0251] FIG. 6C illustrates a tag-applied confirmation report. FIG. 6D illustrates a slaughtered or termination report for an animal. Notably, FIGS. 6A-6D illustrate a technique for outputting confirmation reports. In other implementations, the report may be made via email, a web confirmation page, printed report, electronic text, or some other technique.

[0252] Throughout its entire process, data service provider 5002 can use secure network, database, and computing technologies. At least some of the data collected by the data service provider 5002 can be forwarded to a data trustee.

[0253] B.) Data Trustee

[0254] Data trustees can be used to establish a private sector infrastructure to insure that confidential animal information is not released to the public sector. A number of data trustees, approved by the livestock industry as well as the government, can serve as a buffer between commercial animal information systems and any government sponsored systems. They can be certified with standardized criteria and consent to be audited by industry associations and other oversight groups. Once certified, data trustees can be used to contribute data to the official database and to provide government officials with animal trace reports. Data trustees also provide tools to receive, store and report data to the USDA for various purposes, including disease surveillance and health management purposes. In some embodiments, the functions of the data trustee are performed by the data service provider or the participant.

[0255] As illustrated in FIG. 7, the data service provider 7002 includes elements of software and/or hardware. The relationships shown between the components in FIG. 7 indicate the main flow of information; other relationships are not shown for the sake of simplicity. Depending on implementation, components can be added, omitted, split into multiple components, combined with other components, and/or replaced with like components or systems. Alternatively, a data trustee 7202 with different components and/or other configurations can be used to perform one or more of the techniques described herein.

[0256] FIG. 7 is a block diagram illustrating one embodiment of a data trustee 7202. A data trustee 7202 typically receives data from a data service provider 7002. In some embodiments, this data is stored in a database separate from the official database 7102. The data trustee typically filters non-official data from the official data and forwards the official data to the official database 7102. This helps to ensure that the integrity, security, confidentiality, liability, normal commerce, performance and efficiency goals of the NAIS are met. Screened, official data can be forwarded to a government database 7402 upon request. Using data from the government database 7402, health officials may request a trace report 7302 on a given animal. The data trustee 7202 generates the trace report 7302 upon request. Preferably, the trace report 7302 is generated within a specified, agree-upon time period, such as within 48-hours of request or less.

[0257] 1.) Official Data

[0258] A data service provider 7002 typically sends mixed data to the data trustee 7202. From this mixed data, a filter 7252 can be used to separate official data from non-official data. Official data typically includes the data necessary to trace an animal. For example, the official data may include an animal identifier, a premises identifier, group/lot identifiers, the date and time an animal was at a premises, etc. In some implementations, the data forwarded by the data service provider 7002 includes only the official data. In such embodiments, the data service provider may be acting as a data trustee and filtering non-official data. The official data can be forwarded to a data trustee or directly to the government. In some other embodiments, the data forwarded by the data service provider includes all of the animal information collected by the data service provider. This approach may help to centralize animal data records and providing wider data access to industry members.

[0259] The government may impose requirements on what constitutes official data. For example, currently the government requires access upon request to information describing specific animal events such as when a tag is allocated, when a tag is applied, when an animal is moved into a premises, moved out of a premises, when a tag is lost, when a tag is replaced, when an animal is imported or exported, sightings of animals, when an animal is slaughtered or dies, when a tag is retired, when an animal is missing, veterinarian inspections, drug information, and other such data. Some of this data is confidential, some of it is not. Any data required by the government can be included in the official data forward to the official database. The confidentiality of this data can be protected until a request is issued by the government. For example, the government may not be informed of the actual UAIDs and/or PIDs corresponding to the identifiers in the official database until such information is requested.

[0260] Typically, government and health officials are only granted access to the data after making a formal request to the official database 7102. Alternatively, access is granted only at the discretion of the data trustee 7202 according to specific business and industry guidelines. This protects confidential information from being released to the public at large.

[0261] 2.) Official Database

[0262] After the data trustee 7202 receives data from a data service provider 7002, the official data can be added to the official database 7102 by the data trustee. Preferably, the official database 7102 operates and is supported 24 hours per day, seven days a week, and 365 days per year.

[0263] The official database 7102 can be built from commercially available database services and can include the underlying data, hardware, and software applications required to manage, view, access, add to, delete from, modify, etc., the database. An exemplary official database 7102 is an SQL database with application software built to access the underlying data. Within the official database 7102 are various tables and fields, such as animal identifier, premises identifier, move-in date, move-out date, etc., defined to receive and store information from a data service provider 7002. Alternatively, a different database builder is used, e.g., an XML database, an Access database, a web-enabled database, or any other well-known database management system (DBMS). In other implementations, a custom database built from the ground up is used.

[0264] For ease of administration, the official database 7102 may be spread over multiple computer systems. A data trustee 7202 may receive data for thousands of animals every day. Due to the volume of the information being collected, multiple instances of the official database 7102 may be distributed across many different computer systems, perhaps at different locations, and perhaps even multiple computer networks, in order to handle the load. To maintain consistency throughout the different portions of the official database 7102 and to keep the information current, the database portions typically are synchronized periodically.

[0265] In addition, to protect the integrity of the official database 7102, the data trustee 7002 may use advanced and state-of the art security measures to protect the official database's underlying hardware, software, and data. For example, during transmission to or from the data trustee 7202, the official data may be encrypted using strong encryption algorithms (e.g., those algorithms provided in the Data Encryption Standard (DES), the International Data Encryption Algorithm (IDEA), the RSA algorithm, and Advanced Encryption Standard (AES)). Alternatively, or in conjunction with the strong data encryption algorithms, secure protocols may be used to transmit the official data over a data network. For example, the data may be sent to a secure website, using the secure hypertext transfer protocol (HTTPS). Pretty good privacy (PGP) and secure sockets may also be used to protect the data during transmission. These and other security measures are designed to prevent non-authorized parties from reading or changing the official data.

[0266] Data can be transferred between databases with any off-the-shelf translation and mapping tools to aid in the translation of a submitting database's data element identifier to a standard data element identifier. This technique also may be used to check accuracy.

[0267] Furthermore, once the official data is stored in the official database 7102 other security measures may be used to protect the data. In some implementations, the data trustees 7202 are required to implement strict procedures, such as requiring data trustee employees to display security badges, performing background checks on key personnel, securing computers in restricted-access facilities, requiring users to log on using a registered IP address or network-interface card, and implementing strong authentication requirements for accessing data, to control access to the official database 7102.

[0268] Moreover, additional security measures may be applied to the official database 7102. Exemplary measures include encrypting the data within the official database 7102, adding security policies to the official database that attach privileges and roles to people with access to confidential information, monitoring and logging a user's activities on the official database to detect misuse or serve as an intrusion detection system, labeling certain types of data as confidential and creating strict rules for accessing the data, and auditing connections.

[0269] To provide redundancy and back-up in the event of disaster or failure, backup copies of the official database 7102 may be located in at least two secure and private locations. As a matter of procedure, occasional system checks can be run to verify the consistency of the data in the official database 7102. Other security measures, such as firewalls and other hardware and software measures also may be used to maintain the integrity of the system.

[0270] After the official data is secured, at least a portion of it is screened, filtered, and may be transmitted to the government database 7402. This filtering function can be performed by the data trustee 7202, the data service provider 7002 or even the animal producer.

[0271] In some embodiments, an animal producer or another authorized entity can review an inventory of animals and the locations of the animals. This review can be done, for example, at any time during animal production and from any location, including remote locations, via, for example, data-access portals. In some embodiments, a user may access the data over the Internet, such as using a customizable, web-enabled portable.

[0272] 3.) Filters

[0273] A filter 7252 can be used to screen data to ensure the non-official data is removed from official data being forwarded to an official database 7102 or to a government database 7402. In some implementations, the data is filtered automatically. For example, as animal information is received from a data service provider 7002, specific database rules may be created to automatically forward designated fields of data, e.g., the animal identifier, to the official database 7102 or the government database 7402. Alternatively, data trustee personnel filter the data manually, e.g. they visually review data records and remove non-official data or they copy the official data into a new data record and forward the new data record to the official database 7102 or the government database 7402. Preferably, a combination of both automatic and manual filtering is used. For example, a filter 7252 can be programmed into the official database 7102 that automatically removes all data except for the animal identifier. When a new record arrives, the filter 7252 is automatically applied. Then the filtered data record is sent to a separate repository until it can be reviewed manually to determine if there is any remaining non-official data. This process provides an additional security measure and allows the data to be checked for accuracy before being forwarded to the government database 7402.

[0274] In some cases, there is no government database 7402, only the official database 7102 operated by the data trustee 7202. Under these circumstances, the filter 7252 may be applied after receiving an official request for information from a government official. In other words, a government official typically must request even official information before it is released to the government. In this situation, the filter 7252 is applied just before sending the requested data. Alternatively, the government official may be granted limited access to the official database 7102, e.g., the rights of the government official would be limited to official data.

[0275] In some implementations, received data is checked for accuracy before being filtered. For example, the data trustee 7202, before filtering the data, may verify the accuracy of some of the received data by checking a national premises identification repository to see if a received premises identifier is correct. Additionally, the data trustee 7202 may verify the accuracy of any received animal identifiers. If invalid data is received, the data trustee 7202 likely will report the error to a data service provider 7002 or the animal producer, so that appropriate corrections are made. Alternatively, the identifier checks are performed after filtering.

[0276] The amount of data being filtered is based on predetermined government and business guidelines. In some implementations, all the animal information is filtered except for the animal identifier. The animal identifier is forwarded to the government database 7402 along with the data record address that corresponds to the animal's information in the official database 7102. Alternatively more or less data may be forwarded to the government database 7402.

[0277] This filter 7252 allows the system to effectively address the concerns and the requirements of industry and health officials, protecting producer interests and enabling animal tracing within a short period of time without impeding the normal movement and commerce of animals.

[0278] FIG. 8 shows a technique for screening official data in an AIF. This technique can be performed by the data trustee, data service provider animal producer or any combination thereof. If filtering is performed by the animal producer or the data service provider, there may be no need for a separate entity to serve as a data trustee. In some embodiments a component, group, tool, and/or application performs the technique.

[0279] Typically, a data trustee tool receives (8102) data records from a data service provider. The received data records include official data that allows government officials to trace animals. For example, the received data records can include an animal identifier, a premises identifier, and other official data. Alternatively, the received data contains both non-official and official data.

[0280] Upon receipt of data records from a service provider, the data trustee tool screens (8202) the data for non-official content. If any non-official data is found, the tool filters that data out before forwarding the data record to the official database. In some implementations, any data not specifically required by the USDA is filtered. The filter process is subject to modification based on government and industry regulations.

[0281] After filtering non-official data from the received data, the data trustee tool may pass (8302) the screened data to a government database. The government database provides government officials with access to information that allows the government to begin tracing an animal's location history. For example, if an animal is diagnosed with mad cow disease, out of concern for public health and safety, a government official may use the animal's identifier to look up trace data in the government database. The trace data stored in the database allows the government to request a trace history report of the diseased animal. Using the reports, other animals that have been commingled and/or intimately associated with the diseased animal may be investigated and treated in an appropriate manner, such as by quarantine.

[0282] The various stages of the filtering technique shown in FIG. 8 can be performed separately or in various combinations, such as in conjunction with other stages.

[0283] 4.) Government Database

[0284] Referring back to FIG. 7, the data trustee 7202 can use a filter 7252 to remove non-official data from received data. The official data can be forwarded to an official database 7102 and then, in response to a legitimate request according to the rules, forwarded to a government database 7402.

[0285] The government database 7402, like the official database 7102, can be built from commercially available database services. Included within the government database 7402 are the underlying data, hardware, and software application required to manage, view, access, add to, delete from, modify, etc., the database. An exemplary government database 7402 is an SQL database with application software included to access the underlying data. Alternatively, a different database builder is used, e.g., an XML database, an Access database, a web-enabled database, or any other well-known database management system (DBMS). In other implementations, a custom database is developed. The application which accesses the government database is preferably web-based, although alternative interfaces may be used. Within the database are various tables and fields, such as animal identifier, data trustee data record, etc., defined to receive and store information received from the data trustee.

[0286] For ease of administration, the government database 7402 may be spread over multiple computer systems. For example, due to the volume of the information being forwarded from a data trustee, portions of the government database 7402 may be distributed across many different computer systems and perhaps even multiple computer networks in order to handle the load. To maintain consistency throughout the portions of the government database 7402 and to keep the information current, the database portions can be synchronized periodically.

[0287] The government database 7402 typically stores only premises identification information. When a health related investigation is initiated, the government database 7402 may receive additional information in response to a request using an animal identification related to the investigation. Alternatively a request is made using a premises identification. In some implementations, for every animal record, the government database 7402 stores an animal identifier and a data record address that points to a location in the official database 7102 from which additional animal information can be retrieved. For this reason, the government database 7402 may not implement all of the security measures used to protect the official database 7102, but could if desired. However, to communicate with the official database 7102, the government database 7402 may make use of some of the same security measures. For example, the government database 7402 may employ the tools necessary to decrypt encoded data transfers and data packets from a data trustee 7202. Moreover, in some implementations, other security measures, such as adding security policies to the government database 7402, monitoring and logging user activity on the government database, and auditing connections, are used to prevent non-authorized parties from reading or changing the data.

[0288] To provide redundancy and a fail-safe in the event of a disaster or system failure, the government database 7402 can be backed up on a periodic basis. This may be done by maintaining duplicate instances of the government database 7402 on separate computer systems. If one system fails, the secondary system begins operating. Moreover, storing a duplicate copy of the government database 7402 at an off-site location, backing up the data using a back-up system such as a tape drive, and other similar mechanisms, all insure the consistency of the government database 7402. Occasional system checks may be run to verify the consistency of the data in the government database 7402.

[0289] As with the official database 7102, other security measures such as firewalls and other hardware and software measures may be used to maintain the integrity of the system.

[0290] 5.) Reports

[0291] The data trustee 7202 may provide various reports 7302 to producers, data service providers 7002, government officials and others. Similar to the reports generated by the data service provider 7002, some of the reports 7302 are confirmation reports to confirm that data has been received, recorded, meets NAIS standards, etc. These reports 7302, like the reports 5552 described in connection with FIG. 5, provide information regarding the status of an animal and also provide a chain of custody that shows where an animal has been. The data trustee 7202 also provides animal trace reports, which, unlike the confirmation reports created by the data trustee, are generated in response to a request from government officials and show a complete animal history. Finally, the data trustee 7202 may generate reconciliation reports, which typically are generated in response to a request for reconciliation of data after a discrepancy is detected. Reports generated for providing commercial data to managers, buyers, processors, etc. can be used for process verification.

[0292] a.) Confirmation Reports

[0293] The confirmation reports typically are made in response to animal move events. The confirmation reports may, for example, disclose the factual information regarding the shipping and receiving premises without necessarily disclosing the premises identification numbers of previous premises locations. They allow data service providers 7002 and animal producers to verify that data has been accurately recorded and that data has been properly reconciled within the official database 7102.

[0294] For example, moving an animal from a ranch to a commercial feedlot triggers at least two events: an animal move-out event from the ranch and an animal move-in event at the commercial feedlot. The data service provider 7002 may record these events and forward official data such as the new premises identifier to the data trustee 7202. Upon receipt of the forwarded information, in some implementations, the data trustee 7202 generates in real-time a confirmation report for the animal producer. In other implementations, the data trustee 7202 reconciles the received data against its own records and those records stored at the national premises identifier repository and the official database 7102. If no errors are found, a confirmation report is sent to the data service provider 7002 and/or the animal producer. Similarly, when an error is found, the confirmation report notifies the data service provider 7002 and/or the animal producer of the error.

[0295] In order to protect industry privacy interests, some premises receive a lifetime premises identifier. In the confirmation reports, this information typically is not disclosed. On the confirmation reports, the premises identifier may, for example, be reported as “confirmed.”

[0296] The number and type of reports generated by the data trustee 7202 varies based on government and industry regulation, animal producer and data service provider wants and needs, and other such factors.

[0297] Confirmation reports can be useful to animal buyers. In some embodiments, a buyer may require a confirmation report as a condition of the purchase and may refuel payment if no confirmation report is issued. A buyer may, however, first buy animals without a confirmation report and then later receive a confirmation report at the buyer location or another location.

[0298] b.) Reconciliation Reports

[0299] Reconciliation reports may be generated when a discrepancy arises in the data, such as a discrepancy shown by a confirmation report. Typically, thus type of reconciliation report is generated at the request of a participant, such as an animal buyer. Discrepancies may be caused by a variety of factors, such as lost animals, lost identification devices and data-entry errors. In some embodiments, discrepancies are detected automatically and the participant is given the option of ordering a reconciliation report to identify and address the discrepancy.

[0300] Reconciliation reports also can be generated to reconcile data in multiple databases. For example, a data trustee may send a reconciliation report to a data service provider to ensure that the data is consistent. If differences are found between the data in two or more databases, the source of the data can be investigated to determine which database is in error.

[0301] c.) Trace Reports

[0302] Trace reports typically include a location history for a given animal. For example, whenever an animal is moved, the animal identifier, the new premises identifier, date, time, etc. are all recorded in the official database 7102. In response to a request from a government official, the official database 7102 provides data to the government to generate a report tracing an animal's location history. Alternatively, a trace report may be generated for use by a data service provider, a data trustee or an official database operator according to certain criteria consistent with confidentiality.

[0303] In addition to location histories, a trace report may include future animal locations. For example, if an animal lives sequentially at premises A, B, and C during its lifetime and it is discovered that the animal was exposed to a diseased animal while at premises A, a trace report might specify premises occupied by the animal after location A (i.e., locations B and C). Depending on the required information, a trace report may include all the premises occupied by an animal before an event, after an event or both. The premises information also can be limited to a specific time period, such as a time period in which a cohort was known to have an active, contagious disease.

[0304] In some implementations, generating the trace report involves searching in the official database 7102 for every location an animal has been and reporting the information on that animal alone. Alternatively, when government officials request data for an animal trace, the official database 7102 may provide the data to generate a comprehensive list of animals that have at one time or another commingled, or have been more intimately in contact, with the traced animal. This search involves determining every premises where an animal has stayed. Then the search continues by identifying every animal that has stayed at the same premises. Such a search likely would be computing resource intensive (and may end up listing every cow in the country). Thus, to narrow the search, the data trustee 7202 may add additional search terms to its queries, such as the date an animal was at a premises, a GID, or other piece of data. By focusing the search, the data trustee 7202 can provide a reasonably accurate report of all animals that have commingled with the traced animal. Generally, this is done to identify diseased animals. This type of investigation generally returns only a small percentage of the national herd. Thus, only a small percentage of animals need to be treated as deemed appropriate.

[0305] If a requesting party has proper authorization a trace report also can be generated for commercial purposes. For example, a trace report may include all locations occupied by an animal and all commercial data for the animal.

[0306] FIG. 9 shows an example of a trace report for a single animal. As listed, an animal with an animal identifier of 840 123456789012 lives at three different premises during its lifetime. The animal is tagged at premises AB12345. On Mar. 15, 2005, the animal is sighted on the same premises. Later, the animal is moved to a second premises GHI90JK, where the animal stays for about 5 months. On Dec. 20, 2005, the animal is moved to a slaughter house where it waits to be slaughtered.

[0307] Trace reports can be structured to protect the privacy and security concerns of animal producers. For example, a trace report based on an animal identifier might include the animal identifier and an indication that the animal inhabited a certain number of premises during its lifetime. The exact premise identifiers can be withheld until requested. Similarly, if a trace report is generated for a given location, the report may include that location's identifier and an indication that certain animals occupied the location at certain times. The exact animal identifiers can be withheld until requested.

[0308] After a trace report is generated, if necessary, government and health officials develop an intervention strategy 7502 to keep diseased animals out of the stream of commerce. For example, animals may be treated in any manner appropriate to the situation, such as quarantine, medical treatment, or slaughter. Alternatively, the animals are dealt with in any other suitable manner.

[0309] d.) Tracing Technique

[0310] FIG. 10 illustrates an example of a technique for tracing an animal. Tracing generally includes identifying an animal 10302 (usually a diseased one), requesting a trace report 10402 for the animal, identifying other potentially infected animals 10502, and finally implementing a strategy 10702 to protect people from being infected by tainted meat and to reduce the other effects the diseased animal may have on commerce. Tools, components, and systems such as those illustrated in FIG. 4 can be used to perform the technique. Alternatively, another tool and/or system can be used to perform the technique.

[0311] In a first stage, an animal is diagnosed (10102) with an infectious disease such as mad cow disease. To prevent spread of the disease, health officials attempt to determine what animals have commingled with the diseased animal. This can be done in one of at least two ways. First the health officials using the diseased animal's identifier look up (10302) the data record for the diseased animal in the official database and submit (10402) a formal request for a trace report on the diseased animal. The formal request may be submitted electronically, e.g. through a web page, through a link in a government database application, or by some other means.

[0312] An official database system then processes the request, searching through relevant records to find where the animal has been. Confidential premises identifiers identify more specifically premises locations where the animal has stayed. An initial trace search finds the premises identifiers of locations where the diseased animal has lived and commingled with other animals. These potentially diseased animals then can be identified (10502).

[0313] Subsequent recursive searches (10602) using additional search terms, such as the time and date of move-in, a group number, narrow the search scope and limit the number of animals that need to be quarantined. This process is repeated until a complete list of animals that have commingled with the diseased animal is generated. Then the health officials can take the necessary precautions and intervening steps to quarantine, treat, or slaughter potentially infected animals.

[0314] The various stages of the technique can be performed separately or in various combinations, such as in conjunction with other stages.

V.) Technique for Implementing the Animal Identification Framework

[0315] FIG. 11 shows an example of a technique for implementing the disclosed animal identification framework (AIF). The AIF shown in FIG. 4 can be used to perform the technique. Alternatively, another framework can be used to perform the technique.

[0316] Systems such as those described in connection with the input data sources of FIG. 5 transmit (11102) animal information. In some implementations, the data is transmitted to data collection tools. The transmitted data is collected (11202) by the data collection system and stored in a repository. The transmitted data includes animal information, such as animal identifiers, premises identifiers, and other data that is typically associated with commercial animal data collection services.

[0317] For example, an owner may have a small herd with each animal tagged with an identification device properly encoded with a UAID. To prepare the animals for processing, the owner may move his small herd to a commercial feedlot, which acts as a designated data service provider, so the animals will fatten up before sale. The animals' movements are tracked. When the animals are sent to the commercial feedlot, the animal identifiers and any other information encoded on the identification devices are transmitted to a data service provider, which stores the information and reports to the owner that the animals arrived.

[0318] The data collector system then forwards all or part of the collected data to a data trustee system, such as the data trustee 7002 discussed in connection with FIG. 7. The data trustee system confirms receipt of the information, stores the forwarded information, and removes and/or hides non-official portions of the information (11302). For example, in the scenario described above, the collected data from the small animal herd is forwarded to the data trustee system. The data trustee verifies the owner's premises identifier and the animals' identifiers. A report is sent to the owner either confirming entry of the data in the database or detailing errors found in the data. In either case, the cattle owner has the opportunity to reconcile the data against his own records and correct any errors. In some embodiments, data service providers, data trustees and/or others may verify the validity of data (such as the validity of UAIDs or PIDs) before submitting the data to the official database.

[0319] A portion of the screened data may be sent (11402) to a government-accessible database system, such as the government database 7302 described in connection with FIG. 7. For example, in the above scenario, the data trustee filters non-official information from the data it received and only forwards official information, such as the animal identifier, to the government-accessible database system.

[0320] If one of the cattle owner's animals is diagnosed with an infectious disease, such as mad cow disease, using the animal identifier as a starting point, the government can request a trace report on the sick animal. Alternatively, the government may request a trace report on the premises occupied by the sick animal. As shown with the technique described in connection with FIG. 10, a trace history is generated (11502) by the data trustee system. The trace history provides enough data for government and health officials to impose proper quarantines and other measures to protect the health and well-being of animals, as well as human beings. For example, the diagnosed cow is slaughtered and burned to avoid spreading the disease to other animals. Those animals that had contact with the diseased animal may be quarantined for a period of time to be treated and to see if they manifest any symptoms of the disease.

[0321] In addition to use on animals, embodiments of the disclosed system also may be useful for tracking food products made from animals. The same principles apply. For example, the locations occupied by a food product (e.g., slaughterhouses, processing facilities, distributors and retailers) can be associated with a food product identifier in a database. Each food product can be packaged with a device (e.g., a bar code) encoded with a value that links the food product to the location information in the database. The actual location identifiers, however, can be kept confidential unless a health concern causes a government official to request them. For example, when a tainted food product is discovered, health inspectors may use an identifier for a food product in question to obtain a list of locations associated with the food product. Alternatively, the health inspectors may use a location identifier to obtain a list of food products associated with the location. This would help to protect the public from consuming tainted food products. For added benefit, some embodiments include integrating the disclosed AIF with food product tracking. For example, food products may have identifiers linked to the animal from which they originated.

[0322] Many of the tools and techniques herein can be described in the general context of computer-executable instructions, such as those included in program modules, being executed in a computing environment on a target real or virtual processor. Generally, program modules include routines, programs, libraries, objects, classes, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The functionality of the program modules may be combined or split between program modules as desired in various embodiments. Computer-executable instructions for program modules may be executed within a local or distributed computing environment.

[0323] For the sake of presentation, the detailed description uses terms like “determine,” “generate,” “adjust,” and “apply” to describe computer operations in a computing environment. These terms are high-level abstractions for operations performed by a computer and, in less the context indicates otherwise, should not be confused with acts performed by a human being. The actual computer operations corresponding to these terms vary depending on implementation.

VI.) Determining Respiratory or Circulatory Condition in Animals for Improved Management

[0324] This subsection describes various process steps and system components for evaluating respiratory or circulatory condition in animals and for managing the animals accordingly. These process steps and system components can be used in conjunction with the disclosed AIF.

[0325] Unlike external animal characteristics, the condition of an animal's respiratory and circulatory systems is not readily apparent from a superficial examination. Respiratory and circulatory condition, however, such as respiratory damage from past respiratory disease, is one of the most important aspects of an animal's health.

[0326] Although the majority of this disclosure is directed to the evaluation of respiratory condition, it should be apparent that similar techniques can be used for the evaluation of circulatory condition. For example, the ultrasonic and radiographic imaging techniques described below can be used to generate images of an animal's heart or lymph nodes in addition to its lungs. Information from these images then can be used to make management decisions regarding the animal.

[0327] A.) Imaging

[0328] Some embodiments of the disclosed method include imaging at least one lung of a live animal. Several techniques can be used to image the lungs of live animals, such as ultrasonography, radiography (e.g., standard x-ray and computerized axial tomography) and magnetic resonance imaging. Of these techniques, ultrasonography is the least expensive and is particularly well suited to use on large animals raised for commercial food production.

[0329] Ultrasound imaging involves the direct introduction of high frequency sound waves from a transducer into the tissue to be evaluated. The echo resulting from these sound waves can be recorded as an image that provides valuable information about the internal characteristics of the tissue. The time delay between transmitting the sound waves and recording the echo can be used to indicate the depth of the tissue being imaged. The intensity of the echo can be used to distinguish between different types of tissue, because different materials have different levels of acoustical impedance. In this way, internal structures can be visualized, including overall organs and structures on or within organs, such as lesions.

[0330] Ultrasound imaging conventionally has been used in the obstetric care of livestock and to measure various livestock characteristics, such as back fat thickness and marbling. In very limited circumstances, ultrasound imaging also has been used to view the thoracic organs of live animals, including the lungs. There are two journal articles that describe ultrasound imaging of the lungs of cattle: U. Braun, et al., “Ultrasonographic Findings in Cattle with Pleuropneumonia,” Vet. Rec. 141: 12-17 (1997) and U. Braun, et al., “Ultrasonography of the Lungs, Pleura, and Mediastinum in Healthy Cows,” Am. J. Vet. Res. 57(4): 432-8 (1996). These articles are incorporated herein by reference. Both of these articles describe ultrasound imaging for the purpose of diagnosis of current disease rather than to evaluate damage from past disease.

[0331] Some embodiments of the disclosed method include imaging the lungs of live animals while the animals have substantially no symptoms of active respiratory illness. In these and other embodiments, imaging is not performed for the purpose of diagnosing current disease, but rather for the purpose of gathering information about respiratory condition that can be useful for future management decisions. Lung imaging can be conducted at various times during the lifecycle of an animal. At certain times, information about an animal's respiratory condition is more useful than at other times. In some disclosed embodiments, lung imaging is conducted shortly before a management decision, such as the sale of an animal or the slaughter of an animal. For example, lung imaging can be conducted at auction before an animal is sold, upon purchase of an animal for grazing or feeding or while the animal is undergoing finish feeding at a feedlot. Lung imaging also can be conducted at a time unrelated to the timing of a management decision. Information from such lung imaging can be recorded for later use. The process of recording and using information from lung imaging is described in greater detail below.

[0332] Most livestock require periodic maintenance. To improve efficiency, lung imaging can be conducted in conjunction with other maintenance. For example, lung imaging of cattle can be conducted while the cattle are receiving treatment in a chute or cattle working area. Some embodiments of the disclosed system include a measuring station. The imaging equipment can be stationary or mobile. Efficiency can be improved by successively imaging the lungs of two or more animals.

[0333] The procedure for imaging the lungs of animals can be derived from the imaging procedures used in other contexts. For example, ultrasound imaging procedures for imaging the lungs can be derived from obstetric ultrasound imaging procedures. For example, the lungs of cattle can be imaged with the same equipment used in back fat and marbling measurements. Suitable ultrasound devices include the Alkoa 500 with a 3.5 MHz transducer.

[0334] The transducer used in ultrasound imaging can be positioned externally or internally. If positioned externally, the skin on the thorax in the region of the lungs may be prepared prior to imaging. This preparation can include removing hair and applying a transmission gel or liquid. In cattle, the lungs generally can be observed in the area between the seventh intercostal space and the twelfth intercostal space. To produce images of the lungs, the transducer can be scanned along each intercostal space with its long axis parallel to the long axis of the ribs. The transducer can be positioned internally, for example, by sedating the animal and routing the transducer through the animal's esophagus. This technique is best for imaging the mediastinum rather than the outer portions of the lungs.

[0335] In some disclosed embodiments, ultrasound imaging is combined with an auditory evaluation of internal tissue characteristics. For example, a device can be used that includes both an ultrasound transducer and a stethoscope. Combining these instruments allows for the simultaneous visual and auditory evaluation of the internal tissue. The combined device can include, for example, a stethoscope mounted to an ultrasound transducer such that the diaphragm of the stethoscope is substantially coplanar with the portion of the transducer intended to contact the animal. The acoustical tubing leading to the diaphragm can be integrated with the wiring leading to the transducer. Sounds generated within the internal tissue also can be detected electronically. These sounds then can be reproduced in an earpiece or some other transmission device.

[0336] B.) Evaluation of Images

[0337] A significant amount of information can be gathered from images of the lungs of live animals. For example, these images can provide information concerning both present and past respiratory disease. Present respiratory disease may be observed, for example, as an accumulation of fluid in the pleura. Damage from past respiratory disease may be observed, for example, as scarring, fibrosis, necrosis or other types of lung lesions. Some embodiments of the disclosed method are directed primarily to the evaluation of damage from past respiratory disease.

[0338] Evaluation of the images can be performed at the time of imaging or at a later time. In some disclosed embodiments, a technician images the lungs and records the images, which then can be evaluated by another technician or a veterinarian. Each animal can be assigned a respiratory damage designation corresponding to the animal's degree of respiratory damage. For example, the evaluator may assign a qualitative designation (e.g., good, average or poor) or a quantitative designation (e.g., the percentage of damage).

[0339] Lung lesions in animals are similar in appearance to lung lesions in humans. Thus, information regarding evaluating lung lesions in humans can be used as a guide in the evaluation of lung lesions in animals. Similarly, information regarding evaluating lung lesions in one type of animal can be used as a guide in the evaluation of lung lesions in another type of animal.

[0340] Both ultrasound and radiographic images typically are grayscale images. In such images, a healthy animal lung typically appears with a dark gray border and a lighter gray interior. Lung tissue affected by an active respiratory disease typically appears darker than healthy lung tissue. Lung tissue damaged by a past respiratory disease typically appears even darker than lung tissue affected by an active respiratory disease. In some cases, lung tissue damaged by a past respiratory disease is very dark gray or black. Thus, darkened portions of ultrasound and radiographic images of the lung are evidence of active or past respiratory disease. Additional information can be gathered from the locations of the darkened portions. Respiratory disease typically is most severe in the bottom portion of the lung. Therefore, ultrasound or radiographic images that show dark gray or black areas in this bottom portion are strong evidence of active or past respiratory disease. The exact grayscale intensity differences between healthy lung tissue, lung tissue affected by active respiratory disease and lung tissue damaged by past respiratory disease can be discerned by comparing images from several animals, including animals with each of these conditions.

[0341] C.) Livestock Management

[0342] Information gathered from images of the lungs of live animals can be used to make management decisions regarding the animals. Such management decisions can include decisions regarding the treatment, care or disposition of the animals. Some examples of animal management decisions, as well as other relevant information, can be found in U.S. Provisional Patent Application No. 60/645,462 and U.S. Pat. Nos. 6,805,075, 6,736,272, 6,592,517, 6,579,236, 6,547,726, 6,516,746, 6,318,289, 6,200,210, 6,135,055, 6,131,744, 6,000,361, 5,836,880, 5,803,906, 5,673,647, 5,573,002, 5,401,501, 5,369,032, RE34,776, 5,340,211, 5,315,505, 5,219,224, 5,008,821, 4,910,024, 4,889,433, 4,815,042, 4,733,971, which are incorporated herein by reference.

[0343] After evaluating respiratory damage, such as from an ultrasound or radiographic image, the designation corresponding to the degree of respiratory damage can be recorded. To facilitate recordation of the respiratory damage designation, some embodiments of the disclosed system include a data entry device near the measurement station where the respiratory damage is imaged or evaluated. Each designation can be associated with a unique identifier for the animal being assessed. This facilitates later reference to the respiratory damage designation to inform future management decisions. In some disclosed embodiments, the respiratory damage designation is entered and stored in an electronic database. In these and other embodiments, a user may be able to review the respiratory damage designation for each of a plurality of animals from a location remote from the animals.

[0344] As discussed above, livestock with significant amounts of respiratory damage from past respiratory disease typically do not perform as well as other livestock at the feedlot, do not respond as well as other livestock to treatment for active respiratory disease and produce lower quality meat than other livestock. According to some embodiments of the disclosed method, livestock managers can use the knowledge that certain animals will or will not have these undesirable characteristics to make better management decisions.

[0345] One management decision that can be informed by knowledge of respiratory damage is the purchase of an animal. Some disclosed embodiments include providing a respiratory damage designation to a buyer to aid the buyer in a decision regarding the purchase of an animal. Naturally, animals with a greater degree of respiratory damage may be purchased for a lower price than animals with a lesser degree of respiratory damage. In some cases, a lower purchase price may offset the additional risks associated with investing in an animal with significant respiratory damage.

[0346] Aside from purchase of an animal, respiratory damage information also may be useful for determining whether to treat an animal for a respiratory illness diagnosed after the respiratory damage information is gathered. As discussed above, treatment can include the administration of drugs, which can be expensive. A decision may be made, for example, not to incur the expense associated with treatment of animals with significant respiratory damage from past respiratory disease because these animals are less likely to recover than other animals. Alternatively, a decision may be made to treat animals with significant respiratory damage from past respiratory disease more aggressively than other animals if such treatment may prevent the otherwise likely death of such animals.

[0347] Other management decisions that may be affected by an animal's respiratory condition include how the animal should be fed and housed prior to slaughter. Typically, livestock are fed at a feedlot for several months prior to slaughter. Animals with significant respiratory damage gain less weight per day at a feedlot than other animals. Thus, a decision can be made to lessen or avoid the expense associated with the animal's stay at a feedlot. For example, animals with significant respiratory damage can be housed at a feedlot for shorter amounts of time than other animals or sent directly to slaughter without spending any time at a feedlot. The rates of respiratory disease increase dramatically while an animal is housed at a feedlot and animals with significant respiratory damage are less likely to recover from respiratory disease than other animals. Thus, bypassing the feedlot stage or shortening the amount of time an animal is housed at a feedlot also may help prevent the premature death of animals with significant respiratory damage. If an animal is sent to a feedlot, the animal's respiratory condition may affect management decisions regarding how the animal should be fed. Animals with significant respiratory damage, for example, may require less feed than other animals.

VII.) Electronic Cattle Management

[0348] This subsection describes various process steps and system components for electronic animal management. These process steps and system components can be used in conjunction with the disclosed AIF.

[0349] FIG. 12 illustrates a feedlot 10 which would typically include a series of feed pens (not shown) where cattle would be fed selected feed rations and watered during their stay in the feedlot. For example, four feed pens A, B, C and D are illustrated schematically in FIG. 18. In addition to feed pens, a feedlot incorporating the cattle management system and method includes an alley 12 leading through a series of manually or power-operated gates 14, 16, 18 and a one-way gate 20 to a chute 22.

[0350] The alley 12 leads from an alley 24, which communicates with both feed pens and receiving and holding pens, where cattle are received and held for a short period upon their delivery to the feedlot from a producer. The intersection of alley 24 and the alley 12 leading to the chute 22 is gated as indicated at 26 and 28 to control the admission of cattle into alley 12 leading to the chute and to control the exit of cattle from sorting pens indicated at 30.

[0351] Gates 14, 16 and 18 subdivide the upper curved portion of the alley 12 into cattle holding sections 190, 192 of about 40 head apiece so as to control the delivery of cattle into a crowding section 32 through a crowd gate 18. The crowding section 32 narrows from its entrance to the one-way gate 20 so that cattle are forced single file through the gate 20 and into the chute area 22 which is a single-file chute.

[0352] Chute section 22 is subdivided into a series of longitudinally arranged stations 34, 36, 38, 40 and 42. These five stations are separated from one another and from the entrance 44 to the chute by entrance and exit gates 46, 48, 50, 52, 54, 56. The stations defined by these gates are only large enough to receive one animal at a time. The opening and closing of these gates are controlled by position sensors such as photoelectric cells under computer control to control the one at a time movement of animals through the chute. A larger scale depiction of the chute will be seen in FIG. 16.

[0353] Just downstream of the single-file chute are a series of the previously mentioned sorting pens 30, there being nine such pens illustrated in FIG. 12, including pens 30A, 30B, 30C, 30D, 30E, 30F, 30G, 30H and 30I. Below these pens in FIG. 12 is an alley 58 leading from the left-hand pen exits to the alleys 12 and 24. In addition, there is a single-file narrow alley 60 between the left-hand series of sorting pens 30A, 30C, 30D, 30E, 30G and the right-hand series of sorting pens 30B, 30D, 30F and 30H. From the layout of FIG. 12 it will be apparent that any animal proceeding through the chute and not sorted into one of the sorting gates 30A-30H will automatically end up in sorting pen 301.

[0354] Alley 60 is normally isolated from the entrances to each of the eight sorting pens 30A-30H by a computer-operated entrance gate 62 at the entrance to each sorting pen. It will be noted that there is no entrance gate to the final sorting pen 301. Each sorting pen also has an exit gate 64 at its opposite end opening into an alley used to direct the cattle from the sorting pens to another destination to be described in greater detail below. The exit gates 64 on pens 30A, 30C, 30E and 30G on the left-hand side of the alley 60 in FIG. 12 open into an alley 66 leading through control gates 68, 70 back to alley 58 where cattle can be directed either back through alley 12 or into alley 24 leading to the feed pens.

[0355] Each station of the single file chute 22 is set up either to prepare each animal for measurement or processing, or to actually measure or process the animal. For example, in FIG. 12, station 34 is termed the “get ready” station where one animal is admitted from the chute entrance area 44. Once the animal enters the “get ready” station 34, gate 46 closes and gate 48 remains closed so the animal remains isolated at that station. Then gate 48 is opened so that the animal enters the next station 36. Station 36 is where certain external dimensions of each animal are measured. This is preferably done through a video-imaging device or scanner suitable for this purpose such as one known commercially as an MSI Scanner available from Cattle Scanning Systems (C.S.S.) of Rapid City, S. Dak. Another video-imaging measurement system for cattle is disclosed in Hayes, U.S. Pat. No. 4,745,472.

[0356] After the animal's external dimensions are measured, gate 50 is opened and the animal proceeds into the third station 38 in the chute, which contains a scale on which the animal is weighed. The scale used can be any of a number of commercially available scales but should be capable of generating an electronic signal for recording the weight at a remote location. Also at the scale station or at another desired station, an electronic identification (EID) tag is attached to the animal's ear. This EID tag remains attached to the animal throughout its residence in the feedlot and its shipment to the packing plant where it is removed upon slaughter. Through this EID tag, the animal can not only be identified but its location can be tracked and its measurement and performance data correlated to the animal throughout the duration of its feedlot stay, through its shipment to the packing plant, and until slaughter. One suitable EID tag for this purpose is manufactured by Allflex International and is described in greater detail in U.S. Pat. No. 5,315,505. The disclosure of U.S. Pat. No. 5,315,505 is incorporated herein by reference. The Allflex EID tag is a transponder which operates through a nearby antenna and an integrator reader also available from Allflex International. Each EID tag emits a signal unique to the animal to which it is attached, which is electronically “read” by the antenna and communicated to a host computer via a computer interface unit.

[0357] After an animal's weight is recorded and its EID tag attached, it moves through gate 52 to the next measuring station 40 where its internal backfat content is measured using an ultrasound measuring means and technique. For this purpose, the animal must be held fairly still, station 40 is a “squeeze chute,” well known in the feedlot industry. The squeeze chute has a rear gate that pushes against the rear of an animal while its head is stabilized in a “head catcher.” The ultrasound measuring system used at station 40 is similar to the experimental system used by Professor John Brethour at Kansas State University's Fort Hays Experiment Station, described in the September, 1994 issue of D J Feeder Management magazine. While the animal is within measuring station 40, circulatory or respiratory system imaging also can be performed, as discussed above.

[0358] After backfat measurement, the gate 54 is opened and the animal proceeds to station 42 for processing. Station 42 is also a squeeze chute. Typically, processing at station 42 will include individual drug administration, growth hormone implantation, castration and dehorning. After processing, the chute gate 56 is opened and the animal is sorted into one of the sorting pens in a manner to be described hereinafter.

[0359] The enlarged schematic version of the single-file chute 22 shown in FIG. 16 is sufficiently similar to the chute 22 shown schematically in FIG. 12 that the same reference numerals will be used in describing both chutes. With reference to FIG. 16, it includes the same five processing and measuring stations 34, 36, 38, 40 and 42 as in FIG. 12. However, at the downstream end of the chute 22 of FIG. 16 there are only seven sorting pens 30 shown and designated sort pens 1-7, rather than nine such pens as shown in FIG. 12.

[0360] As shown most clearly in FIG. 16, the single-file chute includes at its downstream end just downstream of chute exit gate 56 from the processing station 42 a pair of access gates 72, 74 for the admission of feedlot personnel into the chute when necessary. These gates may be manually operated.

[0361] From FIG. 16 it will also be apparent that sorting into one of the several sorting pens is accomplished after each animal proceeds through all five stations of the chute by opening an entrance gate to one of the sorting pens while the others remain closed. Thus, for example, if an animal is to be sorted into sorting pen 3 in FIG. 16 its entrance gate 62 would open to the position 62a shown while the entrance gate 62 to all other sorting pens remain closed, thereby directing the animal into sorting pen 3.

[0362] As previously mentioned, each sorting pen entrance gate 62 and each of the chute gates 46, 48, 50, 52, 54 and 56 is operated via position sensors indicated schematically at 76 in FIG. 16 in conjunction with a host computer 78 through chute gate interfaces indicated schematically at 80. Similarly, sort pen entrance gates 62 are operated by the position sensors 82 controlled by the host computer 78 through the sort gate interfaces 84.

[0363] The measurement taken at each of the measuring stations 36, 38 and 40 of the chute, for each animal passing through the chute, transmits a signal indicative of the measurement for that animal through an appropriate interface to the host computer 78, where the measurement data is entered and stored for use in calculating various performance characteristics of the animal.

[0364] Each measurement is correlated with a specific animal through the animal's EID tag as it passes from station to station through the chute. More specifically, the video imaging measurement (VIM) data is transmitted through a VIM interface 86 to the host computer 78. Weight data for the same animal is transmitted from the scale at station 38 through a scale interface 88 to the host computer 78. Then the ultrasound data for the same animal is transmitted through the USBF interface 90 to the host computer 78. The ultrasound data can include, for example, backfat data and respiratory condition data. Finally, any drugs administered to the animal or other procedures performed on the animal at the processing station 42 are transmitted through the processing interface 92 to the host computer where such data is correlated with the animal processed.

[0365] Reference is made to the aforementioned U.S. Pat. No. 5,315,505 for a detailed description of how animal health data and drug administration data would be entered into the host computer from a processing station for a given animal.

[0366] With reference to FIG. 13, a pen sorter 94 is disclosed. There could be one or several pen sorters 94 in a feedlot. Also, it is possible that the sorting portion of the pen sorter 94, which portion is to be described presently, could be designed as a portable unit that would be transported to a particular feed pen within the feedlot for use there within the 30 days or so prior to scheduled shipment of the group of animals within the feed pen so that the shipment date for each animal in the pen could be optimized for maximum feed efficiency and value.

[0367] In any case, the pen sorter is designed to enable weighing of individual animals on a frequent basis, such as daily or even more frequently, without removing the animals from their feed pens and without the need to send them back through the single-file chute described with respect to FIGS. 12 and 16.

[0368] The illustrated pen sorter 94 is subdivided into two feed pens 95, 96 designated feed pen A and feed pen B, separated by a partition or fence 97. Each feed pen in turn is also separated by partitions 98, 99 from adjacent water pens 100, 101, designated water pen A and water pen B. Water pens A and B are, in turn, separated from adjacent shipping pens 102, 103 by partitions 104, 105, the shipping pens being designated ship pen A and ship pen B. The ship pens in turn are separated from one another by another fence or partitions 106. Each feed pen includes a feed bunk 108 into which the daily feed ration of the animals in those pens is deposited and to which the animals in the feed pen have ready access. The water pens and ship pens are provided with respective watering troughs 110, 111, 112 and 113 so that the animals within those pens can access drinking water as desired.

[0369] The heart of the pen sorter 94 is its array of gates for directing animals in the feed pens A and B to desired locations within the larger confines of the pen sorter 94, on an individual animal basis, based on measured performance characteristics of each animal, other data such as market conditions, and a desired shipping date.

[0370] First it should be noted that animals within feed pen A are free to pass between such pen and its adjacent water pen A through a two-way gate 114 to access feed and water as desired. The same is true with respect to animals within feed pen B through a two-way gate 115 between feed pen B and water pen B. However, unless desired by feedlot personnel or dictated by the management system, cattle cannot pass from one feed pen to another or from one water pen to another and cannot pass from either water pen into either shipping pen.

[0371] A single scale stall 116 is positioned between water pen A and water pen B and is sized to accept one animal at a time. The scale stall is equipped with one scale at 117, which can be of a type similar to that used in the scale station of the single-file chute as previously described. The scale is set up to transmit automatically the weight reading of an animal through a suitable interface to the host computer. To identify the animal being weighed, the stall is also equipped with an EID tag identification means as previously described for receiving and transmitting the identification of an animal being weighed to the host computer.

[0372] Access to the scale stall is either from feed pen A or feed pen B, as desired, through one of two shuttle gates 118, 120. Both shuttle gates 118 and 120 comprise a pair of parallel gate arms 121, 122 which move in unison from a scale entrance position, as shown with respect to shuttle gate 120, to a scale blocking position, as shown with respect to shuttle gate 118 in FIG. 13. When in its scale blocking position, each shuttle gate has its arms 121, 122 directed toward a one-way gate leading into the adjacent water pen. For example, feed pen A shows shuttle gate 118 with its shuttle arms in a position for directing animals through the one-way gate 124 into water pen A. When shuttle gate 120 is in a comparable position, its arms would direct cattle through a one-way gate 126 into water pen B. Thus, depending on the position of shuttle gate 118, animals from feed pen A can be directed either through one-way gate 124 into water pen A or into the scale stall 117. A one-way gate 128 at the entrance to the scale stall prevents an animal that has entered the scale stall from backing out. Similarly, an animal within feed pen B can be directed by shuttle gate 120 either into the scale stall 117 to be weighed or through the one-way gate 126 into water pen B.

[0373] Of course, it will apparent that an animal in feed pen A or in feed pen B can at any time pass through the two-way gates 114 and 115 between those pens and their respective water pens A and B, and back again to their respective feed pens. It will also be apparent that any animal within water pen A can also pass through a one-way gate 130 back to feed pen A. However, unless other control gates are operated, an animal in water pen A cannot pass to either shipping pen A or shipping pen B or into feed pen B. Similarly, any animal in water pen B can pass through either the two-way gate 115 or a one-way gate 132 back to feed pen B but cannot pass into shipping pen B, feed pen A or water pen A without operation of appropriate control gates.

[0374] Once an animal is within the scale stall 116, it must pass forwardly out of the stall through a complex array of sorting gates indicated generally at 134 into one of four pens, either water pen A, shipping pen A, water pen B, or shipping pen B. The operation of the sorting gate array 134 is under computer control. The scale stall 116 is provided with an EID tag antenna to identify the animal within the scale stall to the computer system, which then determines which pen the animal is to proceed to from the scale stall, after which the computer operates the sorting gate array 134 in a manner to direct the animal to the appropriate pen.

[0375] Sorting gate array 134 includes three controllable shuttle gates 136, 137 and 138. In addition, it includes a one-way gate 140 leading from the sorting area just downstream from the scale stall into water pen A, a one-way gate 142 leading from the same sorting area into shipping pen A, a third one-way gate 144 leading from the sorting area into shipping pen B and a fourth one-way gate 146 leading from the sorting area into water pen B.

[0376] The following will illustrate that an animal in, for example, feed pen A can be directed through the scale stall 116 and then either back to feed pen A, to feed pen B, to shipping pen A or to shipping pen B. The same is true with respect to an animal in feed pen B. Thus, pen sorter 94 is capable of effecting a four-way sort.

[0377] To illustrate, an animal in feed pen A with the shuttle gate 118 in the position shown, can pass freely between feed pen A and water pen A and back to feed pen A. However, with the shuttle gate 118 shifted to its position shown in dashed lines in FIG. 13, an animal in feed pen A will be directed through the one-way gate 128 into the scale stall 116 where it will be weighed and identified to the computer through its EID tag. The computer will then determine to which pen it should be sorted from the scale stall and actuate the appropriate gates to accomplish the desired sort. For example, if it is desired to return the animal to feed pen A, sorting gate 136 is shifted downward to its dashed line position shown thereby allowing the animal to move through the sorting area and through the one-way gate 140 back to water pen A where it can move freely back to feed pen A, either through the two-way gate 114 or the one-way gate 130.

[0378] If it is desired that the animal be sorted from feed pen A to feed pen B, sort gate 136 is shifted upward to its dashed line position shown, allowing the animal to travel from the scale stall freely through the sorting area and one-way gate 146 to water pen B, from which the animal can move freely through either two-way gate 115 or one-way gate 132 to feed pen B.

[0379] If it is desired that the animal move from the scale stall 116 to shipping pen A, sort gate 136 is moved to its downward position in FIG. 13 and control gate 137 is moved to its upward position shown in dashed lines in FIG. 13, enabling the animal to travel through the sorting area and through one-way gate 142 into shipping pen A.

[0380] If it is desired that the animal move from the scale stall to shipping pen B, sorting gate 136 is moved upward, control gate 138 is moved downward to its dashed line position, and the animal can thus move freely through the sorting area and one-way gate 144 into shipping pen B.

[0381] From the foregoing it will be understood that animals within feed pens A and B can be weighed as frequently as desired and sorted four ways without moving the animals any appreciable distance. Thus the pen sorter 94 provides an ideal finishing pen for use in determining the exact day within a shipping window of several days when an animal should be shipped to the packing plant for slaughter to realize the maximum return on the investment in such animal, considering animal performance, market conditions and feed efficiency.

[0382] FIG. 14 illustrates a hypothetical timeline in the management of cattle. Upon arrival of a lot of cattle in the feedlot, or before, the prior history of the lot would be entered in the host computer 78, as indicated at 148. Such prior history data is illustrated, for example, in the cattle received report by “load” shown in Table 3A. The report indicates such things as the date the load was received, the load number, the number of head in the load, the sex of the cattle in the load and the average weight of the animals in the load. It also indicates cost information. It also gives information such as the age of the cattle, the breed, the type of pasture the load has been on and health, nutrition, stress and weather conditions applicable to the load. It also indicates the number of days the load has been feeding on pasture. Some or all of this data may be used in later calculations by the computer to determine the optimum end date (OED) or days to finish (DTF), of the group or individual animals in the group. This date is also sometimes referred to as the optimum marketing or shipping date.

[0383] On the day of their arrival, indicated on the timeline at 150, each animal in the load is measured, processed and electronically identified with an EID tag in the one-way single-file chute 22 previously described. Then, if desired, the measured and processed animals may be sorted into the sorting pens 30 in a rough sort by type (breed), weight, age, or a first estimated OED or DTF, although such a first “rough” first sort is optional.

[0384] From the sorting pens, the animals are moved to feed pens, either by sort or on an ad hoc basis, where they are fed for a period of time, such as 45 days as shown in FIG. 14, although possibly substantially longer than that.

[0385] If a 45 day weight or measurement is desired for the animals, they would be moved from their feed pens on the 45th day as indicated at 152 back through the single-file chute, where they would be remeasured. From the initial measurement and remeasurement data, the performance of each animal would be calculated by the computer, and its performance assessed. The animals would then be sorted into the sorting pens 30 according to their performance characteristics. Poorly performing animals would be culled from the group and removed from the feedlot operation as “salvage.” The remaining resorted animals would be returned to the feed pens according to their sorts. Animals with respiratory or circulatory damage indicated by imaging also can be moved to the salvage group.

[0386] Then 60-120 days into the feeding period, indicated by the range 154 in FIG. 14, the animals from at least two feed pens at once would be moved from their pens back through the single-file chute for remeasuring once again on an individual basis. The data from these measurements together with prior data for each animal would be used by the computer to calculate a new OED or DTF for each animal and other performance criteria, such as average daily gain (ADG) and feed proration for each animal. From the single-file chute the animals would be resorted once again according to predetermined criteria such as DTF or OED. A projected shipping sequence for each animal could also be calculated at this time. Then the animals would be returned to the feed pens according to the newly determined sorts. The animals then could be removed from their pens for shipment according to their calculated shipping sequence. Whenever an animal is moved in the feedlot, its identification and data, via computer, moves with it. Its location at any time can be determined remotely by computer, and its performance data assessed.

[0387] Alternatively, a portable pen sorter of the type shown in FIG. 13 could be installed in the feed pen. Each animal would be carefully monitored and weighed, perhaps on a daily basis, until it reached its optimum shipping weight or value, at which time it would be shipped to the packer, indicated at 156.

[0388] Alternatively, animals within the feed pens could be sent to a finishing pen such as the pen sorter 94 shown on FIG. 13 where it would be confined, monitored and weighed frequently within a shipping window such as a 30 day shipping window. Within that shipping window indicated at 158, each animal as determined by frequent weight checks and market conditions, would be directed from its feed pen, such as feed pen A or feed pen B in FIG. 13, to appropriate shipping pen A or B when it is ready for shipment.

[0389] Alternatively, during an animal's shipping window, the animal could be weight checked simply by sending it back through the single-file chute periodically until it reaches its ideal shipping weight, at which time it would be shipped to the packer 156.

[0390] Alternatively, a specific shipping date for a given animal could be determined by issued inspection while the animals are within their 30-day shipping window.

[0391] When the animal leaves the feedlot, its EID tag travels with it. Its historical and performance data records would be maintained by the feedlot, indicated at 160, and also transmitted to the producer, indicated at 162. At the same time, the packer would record the carcass data for each slaughtered animal, identified by its EID tag, and transmit the carcass data, as indicated at 164, to the feedlot and producer for correlation with the animal's live performance data from the feedlot.

[0392] The correlation can be useful to the feedlot in projecting optimum end dates (OED), initial feed proration and production costs for future animals of a given type and similar history. This data can also be useful to cattle producers in determining which breeds and individual breeding animals are most desirable from the standpoint of market value and producing the best quality of beef. The important thing to note is that the performance of each animal is tracked on an individual basis from the time it arrives in the feedlot until the time it is shipped and slaughtered, when its carcass data is collected and correlated with its performance data for use by the feedlot and producer in managing future beef production.

[0393] Another important feature of the system is its ability to update an individual animal's performance projections on a daily basis. For example, the DTF for an animal will be current for the day the projection is assessed. The same is true for other projections such as projected weight, etc.

[0394] Although FIG. 14 illustrates one possible processing sequence of cattle including measuring and remeasuring steps and sorting and resorting steps for optimum feed efficiency and return, many other sequences are possible as illustrated in FIGS. 15A, 15B and 15C. For example in the sequences of FIGS. 15A, 15B and 15C the 45 day remeasurement is eliminated and instead a single 60-75 day remeasurement and uniformity sort are performed.

[0395] Referring to FIG. 15A, a load of cattle is received in the feedlot at 166 and within a few hours, measured at 167 and processed at 168 in the single-file chute. From the chute they are directed into the feed pens at 169 without an initial sort. They are fed in the feed pens for 60-75 days, then returned to the single-file chute for remeasuring at 170 and possibly reimplantation of a growth hormone, if necessary. After remeasuring, the animals undergo a uniformity sort as determined by the computer, and directed into the appropriate sorting pens 172. Upon completion of the sorting operation, they are returned to the feeding pens 174 according to their sort groups and there fed for a period of 60 to 80 days. As the cattle within the feed pens approach their individual optimum end dates they would be selected for shipment either visually, by remeasurement at the single-file chute, or by frequent reweighing in a portable pen sorter of the type shown in FIG. 13. Following selection at step 176 the animal would be shipped as at 178 to the packer.

[0396] The processing sequence of FIG. 15B for an individual animal is the same down through the initial receiving, measuring and processing steps. However after measuring and processing, according to FIG. 15B there is an initial sort step 180 that can be a rough type sort as in FIG. 14 or can be based on a first rough estimated optimum end date for each individual animal. Following the first sort 180, the animals are directed by sort group into feed pens at 169 for a feeding period of 60-75 days. At the end of the 60-75 day period the animals are removed from their pens, either individually or in groups, and returned to the single-file chute for remeasuring at 170.

[0397] After remeasuring in the single-file chute, each animal is resorted at 182 by the computer, which opens the appropriate sorting gates of the sorting pens 30. From the sorting pens, the animals are redirected back to the feed pens at 174 and placed into the pens according to their sorting groups. They remain in the feed pens for a period of 60-80 days, after which they are individually, or by group, selected for shipment, according to their last calculated OED. As previously indicated, this selection for shipment can be fine-tuned through the use of either a portable pen sorter or the pen sorter 94 of FIG. 13. After selection, the selected animals are shipped at step 178 to the packing plant for slaughter, where the carcass data and EID tag are collected.

[0398] The optional cattle processing procedure of FIG. 15C is the same as the procedure outlined in FIG. 15A down through the initial sorting step 172. However, thereafter the animals, according to the procedure in FIG. 15C, are directed back to the feed pens according to sorting group at step 173 for a feeding period of only 30-40 days. Thereafter, the animals, or at least selected animals, from the feed pens are removed to finish feed pens, such as pen sorters 94 in FIG. 13, for a finish feeding step 175 for an additional 30-40 days, which represents the shipping window 158 indicated in FIG. 14. Within the finish feeding pens, the animals can be sorted, resorted, weighed, reweighed and selected on an individual animal basis for sorting to one of the two shipping pens A and B for shipment to the packer at step 178.

[0399] FIG. 18 illustrates, in greater detail, a representative cattle processing sequence in a feedlot. Steps in the processing sequence are numbered 1-9 along the left-hand side of FIG. 18.

[0400] In step 1, as indicated at 184, several lots of cattle arrive at the feedlot at about the same time, indicated as lots 1-4. When they arrive, the previous history data of the lots and individual animals in the lots is entered into the host computer by data entry means (not shown) such as a computer keyboard. The previous history, as already mentioned, may include information such as shown in Table 3A.

[0401] According to step 2, after the cattle arrive they are directed into receiving or holding pens 186, typically by lot, where they are held just prior to initial processing. The time spent in the holding pens 186 will depend on when the lots arrived in the feedlot. For example, when they arrive in the middle of a night, they would be retained in the holding pens until feedlot personnel arrive early the next morning to process them. When ready for processing, the cattle from the holding pens 186 are directed through the appropriate alleys to the one-way single-file chute 22 where they are one-by-one led through the various chute stations, sequentially, including the get ready station 34, the video image measuring station 36, the weighing station 38 and the ultrasound measuring station 40. During this process the EID and visual eartags are applied as well, and the measurement data from each of these stations is transmitted through the appropriate interfaces to the host computer 78 for recording, collection and storage. At the processing station 42 each animal is implanted with a growth hormone, given medication as needed, and dehorned and castrated as needed.

[0402] Using available information and data on the group being processed and the individual animals in the group, an initial optimum end date (OED) is determined, either through calculation by the computer or by the operator. A marketing target grade for each animal and for the group (an average) is also assigned, either by the operator from a list of data or through calculation by the computer, depending on the capability of the computer program used. In addition, at this point a projected feed intake for each animal is calculated and assigned and used in prorating the total feed ration used by a group of animals within a single feed pen, so that a fairly accurate cost of feed per animal can be calculated and assessed to the owner.

[0403] Referring to FIG. 36, the process and formulas for calculating “days to finish” (DTF) is illustrated, followed by an example calculation based on hypothetical measurements of an animal passing through the single-file chute.

[0404] Referring to FIG. 37, an alternative method of calculating DTF for an individual animal is disclosed. Following the figure is an example calculation based on hypothetical measurements taken at two different measuring dates during an animal's feeding period at the feedlot.

[0405] Using the method of FIG. 36, an animal arriving at the feedlot, after being measured in the single-file chute, is calculated to have a projected DTF of 141 days. This represents the total number of days the animal is projected to be at the feedlot before it is ready for shipment to the packing plant. However, according to FIG. 37, the same animal using the different method of FIG. 37, is calculated to have a DTF of 165 days, based on its initial measurements upon arrival at the feedlot.

[0406] In Table 1 there are set forth limiting factors to DTF projections based on maximum and minimum live weight for the animal. An example calculation follows. According to the calculation, if a maximum hot carcass weight of 800 pounds and a minimum hot carcass weight of 500 pounds is desired in the end product, the maximum live weight of the animal should be 1230 pounds and the minimum live weight of the animal should be limited to 768 pounds. Thus, if the OFW (optimum finish weight) as used in the example calculation following FIG. 36 results in a maximum live weight that exceeds 1230 pounds or a minimum live weight of less than 768 pounds, the maximum or minimum live weights from the example calculation of Table 1 should be used in the FIG. 36 calculation rather than the optimum finish weight (OFW) originally used.

[0407] It will be noted that the formula and calculation of FIG. 36 includes a “Cornell Cattle Systems” formulation. This is a well-known formula in the cattle industry which includes inputs of OFW, condition score (backfat measurement), current weight, ration, environmental factors, feed additives and input program used.

[0408] FIG. 38 shows the calculation and the process of calculating feed proration to each animal as determined following the first set of measurements at the single-file chute. FIG. 38 is followed by an example calculation using the formula and method indicated in the figure. In the figure DMI indicates dry matter intake for a given feed period and is indicated hereinafter as (DMI). In the same method of calculation the ADG indicates the average daily gain for a given animal. All other measurements used in the formula will be self-explanatory. As indicated in the formula, the frame score is determined by a formula using both hip height and current weight. The condition score for an animal is determined using both the backfat measurement and current weight. In the example, the proration of feed fed in a given period (P1) is calculated for each animal. From the calculation a proration ratio is indicated and applied to the 780 total pounds of feed fed to a pen of four animals during the P1 feed period, resulting in a feed period total proration of feed among the four animals as indicated in the last column of the calculation. It will be noted that of the four animals, the proration ranges from a low of 190.9 pounds to a high of 206.2 pounds. This feed proration formula and calculation is used only for the first feed period following the first measurement of the animals. Following the second and subsequent measurements, a different feed proration formula and calculation is used as indicated in FIGS. 39a and 39b.

[0409] FIG. 40 illustrates how the calculations of DTF from 2FIGS. 36 and 37 (DTF1 and DTF2) can be used to create an average DTF (DTF3) for use in projecting when an individual animal will be ready to be shipped from the feedlot. The numbers used in 6FIGS. 36, 37 and FIG. 40 are coefficients that are obtained empirically from experience feeding cattle at a prototype feedlot. The coefficients are defined and correlated with the coefficient numbers used, in Table 2.

[0412] The following example illustrates how a final DTF calculation can be made for determining exactly when an animal should be shipped to slaughter, based on economics (value) and the prior DTF1 and DTF2 calculations of FIGS. 36 and 37. FIG. 41 is a graph that plots selling price (left-hand vertical line) and backfat on the animal (right-hand vertical line) along two different curves, in terms of the number of days the animal is on feed (DOF). From the calculations and plotting it is determined, in the example, that the point P4 on the backfat curve should be selected for shipment of the animal. This is at 140 days into the feeding period, the most economical point for shipping. Beyond that point, the animal's backfat will exceed 0.7 inches, resulting in the animal's carcass being degraded and thus becoming less valuable. The P1 and P2 end points would result in a carcass with too much backfat. The P3 endpoint would be below the backfat limit, so the animal can be fed beyond this point to increase its value.

10) Plot the location where total incremental COG=Selling Price ($0.70/lb) on TCOG line at P-2 at 164 DOF to reach 1041 pounds.

11) Plot Back Fat Deposition Rate-use Initial Back Fat in the DTF2 Method Two calculation to determine the rate. The rate is used to compound the initial back fat measurement daily for the entire period and is plotted on the graph as BF.

12) Plot the 0.6 BF Target on the Fat deposition rate line at P-3 for 0.6 at 123 DOF to reach 920 pounds.

13) Final DTF Number in this case is P-4, which is the predetermined maximum Back Fat limit which is selected by the computer program. This is calculated to be 140 DOF at 975 pounds. The final DTF number cannot be P-1, P-2 or P-3 because:

a) P-1 exceeds Maximum BF to incur a dollar discount.

b) P-2 exceeds Maximum BF to incur a dollar discount as well as causing incremental cost of gain to exceed selling price resulting in decreased profit.

c) P-3 is the original BF target but, since the animal is still making profit, it should be fed longer.

[0413] As soon as the animal exits the processing station 42 to enter the sorting pen area, the computer 78 has calculated the indicated characteristics of the animal, such as projected OFW, projected ADG, projected DTF and a projected feed proration ratio according to the formula and process outlined in FIG. 38. At this point a sort may or may not be done as indicated at step 3A of the management process. If a sort is to be done, it would likely be a rough sort by animal type, weight, or OED. At this point it would usually be too early to cull animals from the feedlot because there is no performance data yet accumulated on any animal.

[0414] In the illustration of FIG. 38 the measured and processed animals would go directly to step 4 of the process, which is directly to one of four feed pens 188, feed pen A, feed pen B, feed pen C or feed pen D. There they would be provided a selected feed ration and water for a selected period that may range from 45-75 days but more typically in the 60-75 day range. During this first feeding period each animal's records are maintained and the cost of the feed ration delivered to each pen would be prorated among the individual animals for assessment to their respective owners.

[0415] At the end of the first feeding period, two or more of the feed pen cattle groups in the feed pens A-D are selected for remeasurement at the same time. This selection may be based on one or more of several factors such as the similarity of their group average OED or DTF, breed type, marketing target yields or other factors. Each animal in the selected groups is directed back through, for example, the alley 24 from its feed pen through the gates 26, 28 and back through the alley 12 leading to the single-file chute. Once within the alley 12, the animals are led into two different holding sections of the alley as defined by the manually operated alley gates 14, 16, 18 defining holding sections 190, 192. Each of the holding sections 190, 192 is capable of holding approximately 40 head of cattle. From the holding section 192 the cattle are led through a hydraulically operated crowd gate 18 into the crowding section 32 where cattle are directed one-at-a-time through a hydraulically powered one-way gate 20 leading to a single-file entrance section 44 into the one-way chute 22.

[0416] Then the animals are admitted one at a time and single file into the chute 22 where they are measured externally and internally, and weighed once again. In the processing section 42 the animals may also be reimplanted with a growth hormone as needed. The measurement data for each animal is automatically entered into the computer 78 via data entry means coupled to the measuring apparatus and there correlated with the EID of the animal.

[0417] With the historical data, original measurement data and the remeasurement data for each animal, that animal's performance through the first feeding period can be accurately calculated and gauged, much more so than with the projected performance data from the original measurements alone. Thus, upon remeasurement, each animal's ADG, OFW and DTF (or OED) is recalculated and used as the basis for a prediction of future performance and a shipping date or at least shipping window, using the methods previously outlined with respect to FIGS. 36 and 37, and Table 1. In addition, each animal's feed proration is recalculated using the method and formula outlined in FIGS. 39a and 39b. This gives a much more accurate feed proration for each animal than the initial proration determined according to FIG. 38. This new feed proration will be used to calculate each animal's feed intake for the next feeding period. Of course, for the indicated calculations, both the rate of weight gain (ADG) and the total amount of change (gain) and the fat (fat deposition rate) and external dimensions (frame, muscular growth) are used in calculating the new projected DTF and OEW for each animal.

[0418] At the same time, each animal's DTF as calculated is checked against any drug withdrawal and safe-to-ship information available from the health history of the animal, also stored in the computer system according to the system described in the aforementioned U.S. Pat. No. 5,315,505. Any OED or DTF calculated by the computer or otherwise would be adjusted as dictated by the drug withdrawal and safe-to-ship information from the animal health system and prior to any assignment of the animal to any particular sort group. This drug withdrawal and safe-to-ship check might be done either by computer or manually by the operator. Also before any growth promotant drug or implant is administered to the animal in the processing station, a decision would be made on whether to administer at all based on the calculated DTF or OED, drug cost, and efficacy. In short, no growth promotant drug need be given if the animal is predicted to remain in the feedlot for only a short time following a remeasurement.

[0419] As each animal leaves the single-file chute, the computer has determined its sort group and allocated a particular sort pen in which to direct it from the chute. Steps 6 and 7 of the diagram of FIG. 18 represent a sorting procedure that may be used following a remeasurement. Essentially, each animal is directed to one of the seven sort pens of FIG. 16 temporarily. Each of the seven sort pens indicated in step 6 will receive animals selected according to seven different sort groups. The sort group to which a particular animal is assigned may be based on any one or more of several parameters but most likely will be based on their OED or DTF, their visual scores, their weights, their physical condition, or a combination thereof.

[0420] In the illustration of FIG. 18 there are seven sort groups. These are designated, “sort group 1,” “sort group 2,” “flex group,” “earlies,” “lates,” “reruns,” and “trash.” Before the sorting procedure is over in step 6, these seven sort groups will be reduced to four, consisting of “sort group 1,” “sort group 2,” “earlies,” and “lates.” Each of those four groups will then be directed, in turn, according to step 8, into one of the four feed pens A, B, C or D according to their sort groups. Feed pens A-D in all likelihood will be the same feed pens as used in step 4.

[0421] To explain the sort groups further, “reruns” are cattle for which one or more measurements are missing or a process was omitted after a first pass through the single-file chute. As a result, cattle sorted into sort pen 1 as reruns will be run again through the single-file chute and there sorted into one of the other six groups, as indicated in step 7.

[0422] The “earlies” group consists of cattle that are predicted to have earlier OED's or DTF's than the rest of the cattle being sorted. In other words, they are predicted to have shipping dates to the packing plant considerably earlier than the cattle in the other groups. As indicated, cattle in the earlies group will be directed from sort pen 2 in step 6 to feed pen A in step 8. It should be noted that some of the reruns from sort pen 1, after being rerun, may end up in the earlies group of sort pen 2 and be eventually directed into feed pen A.

[0423] Sort pen 6, consisting of the “lates” group, include cattle that are predicted to have late shipping dates (DTF's or OED's), as compared to the other groups. As indicated in the diagram of FIG. 18, the lates group will be directed from sort pen 6 to feed pen D. The lates group may eventually include some of the reruns of sort pen 1 after the reruns are passed again through the single-file chute.

[0424] The “trash” group is composed of non-performing or poorly performing cattle and are sorted into sort pen 7. These are cattle that have poor ADG's or other physical problems, such as circulatory or respiratory damage, that render them unsuitable for beef production or that are unprofitable to keep in the feedlot. Cattle in the trash group are culled from the rest of the animals, removed from the feedlot and sold as salvage.

[0425] The three remaining groups are sort group 1, sort group 2 and the flex group. Whatever the parameters being used to sort, the flex group consists of animals that are close to the dividing line between sort group 1 and sort group 2. For example if sorting is by weight and sort group 1 consists of a range of lighter weight animals and sort group 2 a range of heavier weight animals, the flex group consists of animals that are somewhere in a weight range between the two principal sort groups.

[0426] For example, after a first pass through the single-file chute, sort group 1 might include 20 animals and sort group 2 might include 17 animals. The purpose of the flex group is to even out the number of animals in each of sort groups 1 and 2. In the given example, if there are 10 animals in the flex group, they would be resorted by sending them through the single-file chute again and redistributing them into either sort group 1 or sort group 2 according to weight. As a result of this resorting process with respect to the flex group, eventually there are no remaining animals in the flex group, as they have all been redistributed to either sort group 1 or sort group 2. In the given example, where sort group I originally includes 20 animals, sort group 2 17 animals and the flex group 10 animals, eventually sort group 1 may end up with 24 animals, sort group 2 with 23 animals and the flex group with none. When the flex group has been redistributed, the animals in sort groups 1 and 2 are directed respectively to feed pens B and C.

[0427] Flex sorting is a method of sorting a group of random animals into sort groups of predetermined size and quantity. The particular measurement that is used for ordering is of minor importance to the flex sorting method, but some examples are current weight, finish date, and finish weight. To achieve this sort, an ordered list of animals is maintained as the data is collected, a sort group is assigned based on the position within the ordered list. As the sorting starts, insufficient data will exist to make reasonable sort decisions, so animals are placed in a flex group until enough data has been collected to be representative of the whole population. This sample size is expressed as a percent of the total population, and is configurable. Other animals that will also be placed in the flex group are ones that are too close to the split between sort groups to be certain to which group they belong. This area of uncertainty is defined by flex percent value, it is also configurable and is expressed as a percent of the data range (i.e. maximum value-minimum value). At the completion of sorting, the animals in the flex group are processed again, this time since all information is known about the population the correct sort decision can be made.

[0443] The above example demonstrates a two-way sort, but it can sort any number of ways. For an n-way sort there are (n−1) median locations within the ordered list to keep track of, but only one flex pen is needed to hold the animals that we are uncertain about. Also, in the example given, the sort was done without any errors or animals in the wrong pen. It is possible for the sort to end up with a different head count in the sort group than expected, or for some head to be in the wrong pen based on their sorting measurement. These mistakes occur mostly at the splits between two sort groups, and involve animals with very close measurements. One thing that should be pointed out is that this sorting method, like a lot of other sorting methods, performs better if the data is random. The worst possible scenario is for the data to already be sorted either ascending or descending.

[0444] One additional feature of this sorting method is the ability to have a human make subjective sort decisions, such as color, before running through the flex sort, in effect having two flex sort sessions running concurrently.

[0445] With the animals in feed pens A, B, C and D for the second portion of the feeding period as indicated in step 8, they may remain in their respective pens until they are ready for shipment. During this second feeding period of typically 60-80 days, selected animals or selected groups of animals may again be remeasured and resorted through the single-file chute and sorting pens if desired or economically feasible. For example the timeline of FIG. 14 indicates two remeasurements and resorts during the feeding period. However FIG. 18 illustrates a single remeasuring and single uniformity sort more like the procedure outlined in FIG. 15A. All of the animals in feed pens A, D have new and more accurate pro rata feed intake ratios assigned to them using the method outlined in FIG. 39a and FIG. 39b, including data such as ADG, gain, external and internal measurements and other factors. Individual animal records are maintained for each animal during its remaining period of time in the feedlot. Additional weight checks or other measurements may be used to monitor actual performance during this second portion of the feeding period to confirm or modify the OED or DTF of each animal.

[0446] Also, as indicated in FIG. 15C, after a certain period within feed pens A-D, one or more of the groups may be sent to pen sorters such as pen sorter 94 in FIG. 13 for finish feeding for the time that these groups will be within their marketing window. This approach allows for “fine-tuning” of the optimum date of shipment for each individual animal based on market conditions and the individual animal's performance in its final days at the feedlot. This selection process, whether accomplished visually, by weight checks or by final feeding in a pen sorter, involves the selection process as indicated in step 8A for shipment of the animal to the packing plant. In the case of a pen sorter, this would involve sorting the animal selected for shipment from the feeding pen portion of the sorter to the shipping pen portion, as previously described.

[0447] Animals may be selected for shipment based on a selected marketing group of animals having the same average OED's or DTF's or on an individual animal basis, depending on how finely tuned the selection process desired. The selection process may be performed visually, by computer or by repeated weight checks as previously described.

[0448] Step 9 of the management system involves shipping the selected animals to the packing plant 156. At the packing plant, the animals are slaughtered for production of beef products for consumption. At the packing plant, the EID tag on each live animal is read and transferred by computer to match the identification on the resulting carcass so that the carcass data can be matched to the live animal performance and history data.

[0449] At the packing plant, the EID tags are removed from the animals and shipped in a container to a reconditioning operation where they are cleaned, tested and sorted for delivery back to the proper feedlot. The carcass data and the disbursements of funds breakdown for the original owners of the animals in a marketing group are transmitted to the appropriate feedlot. This data may also be transmitted to the original cattle producers for use in improving the genetics of the animals for future beef production.

[0450] The feed proration flow charts of FIGS. 38, 39a and 39b have been discussed. Following each table is an example calculation using the formulas and flow diagrams set forth in the figures. These examples set forth the data output from the computer when provided with software for carrying out the calculations set forth in FIGS. 38, 39a and 39b. The examples are for four animals identified as animals nos. 85, 10, 68 and 36. From the examples it will be seen that animal No. 85 had a starting weight of 829 pounds and a calculated optimum finish weight of 1136 pounds. During the initial feeding period P1 the ratio of feed allocated to it was 0.255646, so that out of a total of 780 pounds of feed fed during the first feeding period, 199.4038866 pounds of feed was prorated to it for allocating feed charges. During the next current period CP, the same ratio was used to prorate a total of 3,000 pounds of feed among the four animals, with 767 pounds being allocated to animal No. 85. However from the subsequent calculation, the DMI ratio for animal 85, based on remeasurements and original measurements, changed to 0.253206. As a result, animal 85 in the next feeding period ended up with 1,519 pounds of feed prorated to it out of a total of 6,000 pounds. It will also be noted from the calculations and data output from the computer that animal No. 85, when remeasured, had a weight of 1,028 pounds, up from an 829 pound initial weight. It also ended up with an actual weight of 1,128 pounds at final measurement compared to an original calculated optimum finish weight of 1,136 pounds.

[0451] When the four animals finally left the feedlot, their DMI numbers overall were recalculated to adjust their overall DMI ratios, resulting in a reallocation of the total feed fed to each animal. Animal No. 85 had 2,440 pounds of feed allocated to it out of a total of 9,660 pounds, based on its recalculated overall feed ratio of 0.25262. The final data output from the feed proration calculations is a ratio of feed to weight gain for each animal. Animal No. 85 ended up with a feed to weight gain ratio of 8.17, second highest in the group of four animals considered.

[0452] FIG. 19 is a general block diagram of the data inputs and data outputs to the host computer system 78. There are two categories of inputs, including the group input category 194 and the individual animal input represented by interface 196. The individual prior history of each animal is entered upon each animal's arrival at the feedlot, as indicated by the prior history input 198. Such prior history would include each animal's date of birth and its genetic background. Also entered at initial processing and on subsequent remeasurements would be each animal's weight, hip height, backfat and hide condition as indicated at input 200. These measurements are obtained at the single-file chute in the manner previously described. These individual inputs in turn are transmitted by cable or radio frequency means to the host computer 78 for storage and use in calculating the previously discussed formulas. Group information when transmitted to the computer would include prior history data such as average daily gain while in the pasture and the group condition score, visually estimated at the time of arrival at the feedlot. Other information would include the sex, age, breed and hide thickness breakdown for the animals in the group. These “cattle factors” are also input into the computer through data entry means indicated at 204 and the group input interfaces 194.

[0453] Environmental factors such as air temperature, wind, and pen conditions where the animals came from are also collected and entered through data entry means 206 into the group input interface 194.

[0454] Management factors for each group including implants, ionophores and processing information, are collected and input through data entry means 208 into the computer through the group input interfaces 194. Finally, feed factors, such as ration composition, are input through data entry means 210 and the group input interfaces 194 into the host computer 78.

[0455] Market factors are also part of the data used to calculate the desired computer outputs, such factors including purchase price, cattle futures, basis and premium/discounts for the animals in the group. These market factors are entered through data entry means 12 and the group input interface 194 into the host computer 78.

[0456] With the data collected as described, and the appropriate software, the computer system is able to calculate, using formulas such as the ones disclosed in FIGS. 36, 37, 38, 39a, 39b, and Table 1, such outputs as a projected date to finish (DTF), optimum end weight (OEW), and projected end points such as finish weight, hot carcass weight, yield grade, and USDA quality grade. The computer system also calculates a return on investment including cost, incomes and profit as indicated at 218.

[0457] Examples of the type of data collected, calculated, stored and available in reports generated by the computer system are shown in Tables 3A. 3G.

[0458] Table 3A, the cattle received report by load, has already been discussed. It discloses the information available from the producer and entered into the computer through appropriate data entry means upon the arrival of a load of cattle at the feedlot. This is a “group” report and is the sort of information entered into the computer as indicated at data entry means 202, 204 and 206 of FIG. 19.

[0459] Table 3B is a pen assignment summary report, which is another group type report and gives the sorting pen assignments 1-7 for lot No. 495 of cattle that is to be fed in pens 59, 57 and 58. The number of head of cattle in each pen 10, 11 and 11 for sorting pens 1, 2 and 4 and feed pens 59, 57 and 58 is given. This information is available from the computer after at least one measurement and sort of a lot of animals.

[0460] Still referring to Table 3B, the remaining data in the pen assignment summary report should be self-explanatory, giving information concerning the projected finish weight, the current weight, the frame size and current backfat measurements, on average, for the animals in feed pens 59, 57 and 58. In addition to the averages for each of the indicated measurements, the pen assignment summary report also gives maximum and minimum ranges for the animals in each sort group.

[0461] Table 3C is a sample of a pen assignment detail report generated by the computer system. This report indicates the lot number, the feed pen number, the sort pen number, and the EID tag number of each of the 11 animals in feed pen 57. The report also indicates that the animals in this feed pen have a shipping window ranging from May 14, 1994 to Sep. 28, 1994, indicating that the animals in this group are expected to reach their optimum condition, such as optimum finish weight, sometime within this window. The pen assignment detail report also gives individual animal measurements and calculations including video image dimensions (VID), and projected days to finish (DTF) which is the number of days the animal is projected to require to reach its optimum finish weight. Also indicated is the projected optimum finish weight (OFW), the animal's current weight (CWT), and each animal's average daily gain (ADG). Finally, the pen assignment detail report gives each animal's frame measurement score (FM) and backfat measurement (BF).

[0462] Because of the amount of information available for each animal in each feed pen in the feedlot, and at any time during the animal's stay in the feedlot, it will be readily appreciated how animals can be selected, on an individual basis if desired, for shipment to the packing plant when each animal is in optimum condition for shipment. Simply by taking repeated measurements of each animal as it nears its projected shipping date or optimum finish weight, animals can be selected for shipment and slaughter based on their individual performances and market factors rather than the performances of any particular group, if desired.

[0463] Table 3D and Table 3E are marketing yard sheets that the computer system can generate for each animal in the feedlot. The marketing yard sheet of Table 3D is for the same group of animals as the marketing yard sheet of Table 3E. However the yard sheet of Table 3D gives individual animal data for lot No. 495 of animals on the measurement date of Mar. 30, 1994, while Table 3E gives the data for the same animals in lot No. 495 approximately three weeks later, on Apr. 22, 1994.

[0464] As will be seen by the columns in the marketing yard sheets, each animal is identified by tag number, pen number and lot number. Additional data available in the other columns of both marketing yard sheets include various projections that have been calculated for each animal, a comparison of purchase weight and current weight for each animal, days on feed (DOF) information for each animal, the ration information that applies to each animal, average daily gain (ADG) information for each animal and feed intake information for each animal. Finally, the projected and actual cost information based on various treatments, processing and other factors for each animal is listed.

[0465] Table 3F is a sample of a pen closeout report generated by the computer system as a result of the various inputs, including measurement inputs for each animal and each group of animals. This gives the income and expense information for a pen of animals, broken down to an average cost per head, including feed charges, cattle insurance, yardage fees and processing fees. Other pen information included in the pen closeout report includes such information as total pounds gained by all animals in the pen, broken down to an average gain per head. Also included are average daily gain for each animal, daily feed costs per head, daily total costs per head, total pounds of feed fed for the pen and total pounds per head. Also included is average daily consumption data. Other information includes the cost of the feed fed.

[0466] In the summary at the bottom of the pen closeout report, the profit or loss from the pen is given. In the sample, there was no profit for the indicated pen, which included 10 heifers. Based on the summary, the 10 heifers in the pen had an average incoming weight of 678 pounds and an average outgoing weight of 787 pounds. Each gained an average of 3.21 pounds per day for a total of 34 days on feed. The cost of the gain was $56.21.

[0467] The final sample report is shown in Table 3G which is a Closeout Summary By Lot report. In this case the lot number is 42894, which was included in pen 553, containing a total of 27 head. The total profit for the lot was $4,957.98. Each animal in the report is identified by its visual identification tag number (VID) and the profit from each animal is calculated. In addition, each animal's performance during its stay in the feedlot is calculated. Each animal is listed under its sire and dam. This sort of information is valuable to the cattle producer in determining which sires and dams produce the most profitable offspring. This information is then used in making future breeding decisions.

[0468] A layout of the computer system is shown in FIG. 17. Several different computers are used in the system. First there is a feedlot business systems (FBS) computer 230 located at the feedlot office 232. This computer stores the databases used in the system and performs most of the calculations needed in operating the system.

[0469] Remote from the FBS computer and closer to the chute area 22 are a separate process control computer 234 and an ultrasound computer 236 within a common control cabinet 238. Separate from the control cabinet and the other computers is a video computer 240.

[0470] Basically, the process control computer 234 controls the operation of all subsystems including the stall and sorting gates, weigh scale, ultrasound computer and the video computer. The process control computer communicates with the FBS computer through the modems 241, 242, line 244 and FBS interface 246. The ultrasound computer 236 communicates with the process control computer 234 through a line 248. The ultrasound computer 240 also has an output line 250 to a backfat monitor 252 and an input line 254 from the ultrasound scanner 256 at the single-file chute stall 40.

[0471] The video computer 240 communicates with the process control computer 234 through a commline 258. It also has an output line 260 to a video monitor 262, and input lines 264, 266 to video cameras, including an overhead camera 268 and a side-view camera 270.

[0472] Each animal is weighed by a scale loadcell 272 at the weigh stall 38. The loadcell communicates with the scale 274 through a line 276. The scale in turn communicates with the process control computer through a line 278 and data split 280. Data from the data split also can be communicated via line 282 and a modem 284 and line 286 directly to the FBS computer 230 through the FBS interface 246.

[0473] Data concerning drugs, other animal health treatments and other information about an individual animal at the processing station or stall 42 can be entered into an animal health computer or monitor 288 at the processing station and from there communicated directly through the modem 290 and line 292 and interface 246 to the FBS computer.

[0474] As previously noted, each animal has an EID tag applied to it in the single-file chute to give each animal a unique electronic identification. This identification is transmitted from the EID tag by a probe antenna 294 at the EID/USBF stall 40 through a line 296 from the chute to a tiris relay 298 and from the relay through a line 300 to a tiris EID reader 302. The tiris reader 302 transmits the animal's EID identification through a line 304 to the process control computer 234. Alternatively, each animal's EID tag signal can be received by a hanging antenna 306 at the single-file chute and transmitted via line 308 to the tiris relay 298 and thence through line 300 to the tiris reader 302 and through the line 304 to the process control computer 234.

[0475] The FBS computer not only collects data and uses it to calculate projections, costs and other information used in the management method and system, it also collects data from other sources not shown. For example, the FBS computer performs the regular feedlot accounting functions and generates financial reports. It may also receive and store data from a computerized animal drug inventory control and animal health history and drug treatment system as disclosed in the previously mentioned U.S. Pat. No. 5,315,505. The FBS computer may also collect and store data from a computerized feed additive delivery system such as disclosed in U.S. Pat. No. 4,733,971 and the related patents previously mentioned. The FBS computer may also receive and store data concerning the amount of feed ration delivered to each of the feed pens in a feedlot, including such data collected from a computerized bunk reader system such as disclosed in U.S. Pat. No. 5,008,821. All such information, including the drug usage information, feed ration usage information, and feed additive usage information can be used together with the data concerning each animal collected from the system and other data that may be collected and stored in the FBS computer database to prorate feed ration and feed additive costs to individual animals and thereby calculate the cost of production value and other pertinent information about each animal in the feedlot according to various formulas, a few of which are disclosed as examples and discussed.

[0476] Tables 4A, 4E are sample pages of prompts that are generated by the computer programs that are used in the computer system 78 that operates the described system. The described management system is known as the electronic cattle management system (ECM) which is the computer symbol used to initiate the program. The ECM program includes four session types, one of which is entered to begin the system's operation. In Table 4B it will be seen that certain animal measurements can be keyed in, automatically entered or not recorded.

[0477] Item 7 in Table 4B gives the prompts for entering the type of sorting that is desired such as, for example, a flex sort as previously described.

[0478] At the top of Table 4C, the prompts for entering the number of animals to be sorted into the various sort pens are indicated.

[0479] Table 4D lists the various prompts for processing each animal at the single-file chute. By entering the proper prompt, the computer can be instructed to process the identified animal in a particular way such as by weight, by reading its EID, by ultrasound measurement and/or by taking external video measurements.

[0480] Additional prompts for setting the parameters for measuring and sorting are given in Table 4E and 4F.

[0481] The electronic cattle management system can use a number of different computer programs to run the system as described, the operation and sequencing of which are all controlled by the previously described process control computer 234 shown in FIG. 17. These programs will now be described with reference to their respective flow charts.

[0482] First, control of the operation of the entrance and exit gates at the various stalls or stations in the single file chute will be described. First with reference to FIG. 20A, the get-ready station 34 in the single-file chute includes the entrance or tail gate 46 and the exit or head gate 48 defining the stall. Within the stall are three sensors including a tail sensor 342, a fill sensor 344 and a head sensor 346. These sensors, which may be photoelectric sensors or some other automatic sensors, detect the presence of an animal within the stall space, and when all three sensors detect the presence of an animal, the animal will be contained within the space, whereupon the tail gate 46 can be closed after being opened initially to allow entrance of the animal into the stall space. FIG. 20A also indicates the direction of travel of the animal through the single-file chute and the stall space as indicated by the arrow 316.

[0483] Referring now to FIG. 20B, the computer program for controlling the operation of the tail and head gates 46, 48 is disclosed. This computer program resides in the process control computer 234 of FIG. 17. Although not shown, obviously the sensors associated with the get ready stall and all other stations in the single-file chute and the sort pens, to be described, are in communication with the process control computer.

[0484] First the program is conditioned by another program to be described to get ready to receive the next animal that will proceed through the single file chute, as indicated at step 318. At this point, if the fill sensor is off as indicated at 320, the program assumes that the get ready stall is empty and so commands that the head gate be closed as indicated at step 322. Then the program commands opening of the tail gate 324 to allow the next animal to enter the get ready stall. After the tail gate opens, the program waits until the fill sensor at 326 detects the presence of an animal in the stall. The program then proceeds to the next step to detect when the tail sensor is turned off, at step 328. When this occurs, the program commands closing of the tail gate at step 330. If at step 326 the fill sensor does not detect the presence of an animal, the tail gate will not close. Also, as indicated at 328, if the tail sensor remains on, the tail gate will not close. Only when the fill sensor is on and the tail sensor is off can the tail gate close.

[0485] After the tail gate closes, the program inquires at step 322 whether the next station, namely the video station 86, is ready for the next animal. At this point nothing happens until the processing computer receives an indication that the video station is ready for the next animal. When this occurs, the program, as step 334, signals the video computer 240 to get ready for the next animal. At this point the head gate 48 is opened as indicated at 336. The program then inquires at step 338 as to whether the fill sensor 312 in the get ready stall is off and at step 340 whether the head sensor is off. When both the fill sensor 312 and the head sensor 314 are off, indicating that an animal has left the get ready stall and entered the video stall, the program commands the head gate 48 to reclose as indicated at step 322, and then commands the tail gate at step 324 to reopen to ready the stall for the next animal.

[0486] Referring to FIG. 21A, after the animal leaves the get ready stall 34 it walks through the video stall 36 where it is scanned for external dimensions, and proceeds, without stopping, through the open tail gate 50 directly into the EID/scale stall 38 where the animal is weighed and an EID tag is applied to the animal if necessary and read to identify it. Because of the continuous movement of the animal through the video stall, there are no tail, fill or head sensors in that stall. However the subsequent EID/scale stall requires the animal to stop while it is weighed. Thus, both the tail gate 50 and the head gate 52 must be closed while the animal is contained within the EID/scale stall, identified and weighed. Thus such stall includes a tail sensor 342, a fill sensor 344 and a head sensor 346, all of which communicate with the process control computer. Again, the direction of travel of the animal is indicated by the arrow 316.

[0487] Referring to FIG. 21B, the computer program for operating the tail gate 50 and head gate 52 at the EID/scale station is disclosed. As an animal proceeds through the video stall 36, tail gate 50 will be open if the EID/scale station is ready for the next animal, which will be determined by whether or not the head gate of such station is closed and its fill sensor and head sensors 344, 346 are off. At this point, the EID/scale station computer program 348 is initialized and ready to start its sequence of operation. First, at step 350, the program inquires whether the fill sensor 344 is off. If so, it commands the head gate 52 to close at step 352. Thereafter, at step 354 the tail gate 50 is commanded to open, allowing the next animal to enter the EID/scale stall. Next the program, at step 356, inquires whether the fill sensor is on. If so, it inquires at step 358 whether the tail sensor is off. If so, at step 360, the program commands the tail gate 50 to reclose, whereupon the animal is ready to be weighed and have its EID tag attached if necessary, and read.

[0488] With the animal in the EID/scale stall, the program inquires at step 362 whether an EID identification of the animal is required. If so, the process control computer 234 is commanded to attempt to read the tiris EID reader 302 at step 364. If no EID is required, the program next inquires whether a weight is required at step 366. If so, the process control computer at step 368 is commanded to read the animal's weight from the scale 274. After this, or if no weight is required, the program will inquire at step 370 whether a hip-height measurement of the animal is required. If so, the process control computer is commanded at step 372 to read and record the video measurements communicated from the video computer 240. After the measurements are recorded, if required, the program inquires at step 374 whether measurements are complete. If not, the program will return to step 362 and again proceed through the program to attempt to read the video measurements. Once the measurements have been recorded, the program proceeds at step 376 to inquire whether the next station, namely the ultrasound station 40, is ready for the next animal. Unless the next station is ready for the animal, the head gate 52 will not open. When the next station signals that it is ready, through the process control computer, the head gate 52 is commanded to open at step 378. Next, the program inquires whether the fill sensor 344 is off, at step 380. If not, the program will not proceed to the next step and reclose the head gate. When the fill sensor is off, the program inquires whether the head sensor is off. If the head sensor is off, indicating that the animal has left the EID/scale stall, the program commands the process control computer to reclose the head gate 52. At this point the weighed and identified animal will have entered the ultrasound stall 40, and the program returns to step 352 to command reclosing the head gate in preparation for the next animal.

[0489] Referring to FIG. 20A, the ultrasound station 40 is disclosed as having a tail sensor 384, a fill sensor 386 and a head sensor 388. It also includes the tail gate 52, which is the same gate 52 that serves as the head gate for the preceding EID/scale stall 38. It also includes the head gate 54 which serves as the tail gate for the next processing stall 42. Again, the direction of travel of the animal through the ultrasound station and through the single-file chute is indicated by the arrow 316.

[0490] Referring now to FIG. 22B, the computer program for controlling the operation of the gates and thus the animal within the ultrasound station is indicated at 390. Once initiated, it first inquires at step 392 whether the fill sensor 386 is off. If not, because the preceding animal has not yet left the station, the program will return to determine whether the animal has not yet completed its ultrasound scan. However, assuming that the preceding animal has left the ultrasound station and the head gate 54 is closed, the program commands at step 394 that the head gate be cracked open. Then at step 396 the program commands the processing computer to open the tail gate. When the tail gate is opened, the program inquires whether the fill sensor is on, at step 398. If so, indicating that the next animal has entered the ultrasound station, the program inquires whether the tail sensor is off, at step 400. When the tail sensor goes off, the computer program instructs the computer to close the tail gate, at step 402, whereupon the next animal is fully within the ultrasound station and ready to be prepared for measurement. Once the tail gate is closed, the program inquires at step 404 whether the head catcher is to be employed to stabilize the animal in the station. If it is, the program inquires whether the head sensor is on at step 406. If it is, the program, at step 408, commands closing of the head gate.

[0491] Once the head gate is closed, the program at step 410 inquires whether the animal is to be “squeezed” within the station. This has reference to the device at the station commonly referred to as a “squeeze gate,” which in effect squeezes the animal from behind into tight confinement within the stall so that it cannot move to any appreciable extent. If the answer is yes, the squeeze gate at 412 is commanded to close at step 412. If the answer is no, the squeeze gate is not actuated. In either case, the next programming sequence is an inquiry as to whether the animal's backfat is to be measured, at step 414. If the answer is yes, the program will attempt to take a reading from the ultrasound computer at step 416 to record the backfat measurement. If the answer is no, the program inquires whether all measurements are completed at step 418. This is also the next step after a backfat ultrasound reading is attempted at step 416. If the answer is no, the program will again attempt to take a backfat measurement. If the answer is yes, the program inquires whether the next station in the chute is ready for the animal, at step 420. If not, nothing further happens until the next station is ready for the animal. When that occurs, the head gate 54 is commanded to open at step 422. When the head gate is open, the program inquires at step 426 whether the fill sensor is off. If not, nothing further happens until the fill sensor is off. When that occurs, the program inquires at step 426 whether the head sensor is off. If not, nothing further happens until the head sensor is off. When that occurs, the program returns to step 394 to cause the head gate to crack, ready for the next animal.

[0492] Referring to FIG. 23A, the animal proceeds from the ultrasound station 40 into the processing station 42 through the head gate 54 of the ultrasound station, which becomes the tail gate 54 of the processing station. Within the processing station are three sensors, a tail sensor 428, a fill sensor 430 and a head sensor 432.

[0493] Referring to FIG. 23B, the computer program for the processing station, indicated at 434, first inquires whether the fill sensor 430 is off, at step 436. If not, the head gate 56 will not close until the fill sensor does indicate that the preceding animal has left the processing station. When the fill sensor is off, head gate 56 is commanded to close at step 438 and the tail gate 54 is commanded to open at step 440 to admit the next animal into the processing station.

[0494] Next, the program inquires whether the fill sensor is on at step 442. If not, nothing further happens until the fill sensor is on. When that occurs, the program inquires whether the tail sensor 428 is off, at step 444. If the tail sensor is not off, the tail gate 54 will not close. When the tail sensor is off, indicating that the animal is completely within the processing station, the tail gate 54 is commanded to close at step 446. When the tail gate is closed the program, at step 448, inquires whether there is to be a head catch. If the answer is yes, the program inquires at step 450 whether the head sensor 432 is on. If not, nothing further happens until the head sensor is on. If the answer is yes, the head gate 56 is closed at 452 to catch the animal's head.

[0495] Next, the program inquires whether the animal is to be squeezed by the squeeze gate within the processing station, at step 454. If not, the program proceeds to the next processing sequence. If the answer is yes, the squeeze gate at the processing station is commanded to close at step 456 to confine the animal within the station. After the squeeze gate is closed, the program proceeds to the next processing sequence.

[0496] The next inquiry, at step 458, is whether the animal needs to be identified by its EID. If the answer is yes, the program instructs the process control computer at step 460 to attempt to read an identification from the tiris. Nothing further happens until the animal is identified. When the animal has been identified or if no identification is needed, the program inquires whether a sort pen for the animal is required, at step 462. If not, a status light on a control panel (not shown) at the processing station is commanded to indicate, at step 464, that the animal is ready to be released from the single-file chute.

[0497] If a sort pen is required, the program at step 466 inquires whether the animal data has been sent to the FBS computer. If the answer is no, the data is sent to the FBS computer, at step 468. If the animal data has already been sent to the FBS computer, the program bypasses step 468 and attempts to read the correct sort pen for the animal as determined by the FBS computer at step 470. The program then returns to the sort pen required inquiry step 462. If a sort pen is still required then the just described steps are repeated. If a sort pen identity is not required, then the program proceeds on through the sequence and the ready to release status light is illuminated on the aforementioned control panel.

[0498] Thereafter, an operator must manually press a release button to release an animal from the single-file chute into the alley between the sort pens. At this point the computer inquires whether the release button has been pushed, at step 472. If the answer is no, nothing further happens until the release button is pushed. When the release button has been pushed, the program inquires whether the sort pen is ready, at step 474. If not, nothing further happens until either the release button is pushed or the sort pen is ready. When the sort pen is ready, head gate 56 is commanded to open, at step 476. When the head gate is open, the program inquires whether the fill sensor is off, at step 478. If not, nothing further happens until the fill sensor is off. When it is off, the program next inquires whether the head sensor is off, at step 480. If not, nothing further happens until the head sensor is off. When it is off, the program returns to step 438 to close the head gate and prepare the stall for the next animal.

[0499] Referring now to FIG. 24A, the seven sort pens 62 and their respective sorting pen entrance gates 62 are illustrated schematically. The direction of travel of the animals through the alley 60 between the two rows of sorting pens is indicated by the arrow 316 as they leave the single-file chute indicated generally at 22.

[0500] FIG. 24B is a flow diagram of the computer program 482 for operating the sort pen entrance gates 62. The first step in the programming sequence is to make sure all sort pen gates are closed at step 484. Next, the program at step 486 inquires of the process control computer whether a sort pen is requested. If not, nothing further happens and the sort pen gates remain closed, and each animal would travel through the alley 60 to an appropriate feed pen through the open gate 62 of feed pen 7 as indicated in FIG. 24A.

[0501] If a sort pen is requested, the designated sort pen is commanded to open at 488. When the sort pen gate is open the program inquires whether the sort pen gate sensor (not shown) has been tripped, at step 490. When the sort pen gate sensor is tripped, it would indicate that an animal has entered the sort pen through the open gate. The sort pen sensor, such as a photocell, would be located at the gate entrance so that its beam would be interrupted when an animal passes through the entrance into the pen with the gate open. After the sort pen sensor has been tripped, there is a five second delay, indicated at step 492, to give the animal time to pass through the open gate into the designated pen. Thereafter, the entrance gate is commanded to close again, as indicated at step 494. When the designated sort pen gate is closed, the program returns to step 486 to inquire if a sort pen is requested for the next animal. Nothing further happens until a sort pen is again requested.

[0502] FIG. 25 is a flow diagram for the computer program in the process control computer that operates in conjunction with the measuring and processing station and sort pen operating programs to control the sequence of operation of the various station head and tail gates and sort pen entrance gates. The FIG. 25 program, indicated generally at 496, is for controlling the movement of a single animal through the single-file chute and its measuring and processing stations and into one of the selected sort pens. The processing sequence program 496 starts at step 498 by closing the GR1 stall head gate and opening the GR1 stall tail gate. Then at step 500 it asks whether there is an animal in the GR1 stall. If not, nothing further happens until an animal enters the GR1 stall.

[0503] When there is an animal in the stall as indicated by the fill and tail sensors in the stall, the GR1 tail gate is closed at step 502. Then the program asks if the video and scale/EID stations are ready for an animal, at step 504. If not, nothing further happens until those stalls are empty and ready for the next animal. When they are, the GR1 head gate opens at 506. Then, at step 508, when the sensors in the GR1 stall indicate that the stall is empty, the GR1 head gate closes at step 510. As the animal passes from the GR1 stall through the video stall the video measurements are made under control of the video computer, as indicated at step 512.

[0504] The animal passes from the video stall into the scale/EID station or stall as indicated at step 514. When the sensors in the scale/EID station indicate that an animal is in the station, the scale/EID tail gate is closed at step 516. Thereafter, the animal is weighed in the scale/EID station as indicated at 518. Next, there is an attempt to read the animal's EID identification at step 520. Thereafter, the program inquires whether the ultrasound station is ready for the animal at step 522. If not, nothing further happens until the ultrasound station is ready. When ready, the head gate of the scale/EID station is opened at step 524 so the animal can pass into the ultrasound station. Next, the program asks at step 526 whether the animal is gone from the scale/EID station. If not, nothing further happens until the program is told that the animal has left the station. When the animal is gone from the scale/EID station the scale/EID head gate is closed at step 528.

[0505] Next, the program asks at step 530 whether there is an animal in the ultrasound station. If not, nothing further happens until an animal is detected in the ultrasound station. Then the ultrasound tail gate is closed at step 532. Thereafter, the ultrasound computer operates the ultrasound machine to make the backfat measurements at step 534, and the process control computer is commanded to read the video measurements at step 536 by the processing station program.

[0506] Next, the processing station program asks whether the processing station is ready for the animal, at step 538. If not, nothing further happens until the processing station has cleared the previous animal and is ready for the next animal. Then, the ultrasound head gate is opened at step 540, allowing the animal to proceed into the processing station. Thereafter, the program asks whether the animal is gone from the ultrasound station, as indicated at step 542. If not, nothing further happens until the animal has cleared the ultrasound station. Thereafter, the ultrasound station head gate is closed at step 544.

[0507] Next, the program asks whether the animal has entered the processing station at step 544. If not, nothing further happens until the animal is fully within the processing station, after which the processing station tail gate is closed at step 546. After the animal is within the processing station, its EID identification is read at step 548, its measurement data from the previous measuring stations is transmitted to the FBS computer at step 550, and the FBS computer transmits to the process control computer the assigned sort pen for the animal at step 552.

[0508] At this point, within the processing station, the animal may be implanted with growth promotants or undergo additional treatment that may be indicated. When this processing is completed, a button is manually pushed by an operator to indicate that the animal is ready to leave the processing station. The computer program then asks whether the release button has been pushed at step 554 and if not, nothing further happens and the animal cannot leave the processing station. When the release button has been pushed, the program inquires whether the assigned sort pen is ready for the animal, at step 556. Until the designated sort pen is ready, nothing further happens and the animal remains in the processing station. When the sort pen is ready, the processing station head gate is opened at step 558 and the specified sort pen gate is also opened at step 560, so the animal can leave the processing station and proceed into the sort gate alley and into the open sort pen.

[0509] Next, the computer program asks whether the animal has left the processing station at step 562. If so, the head gate of the processing station is closed at step 564. Next, the program asks whether the sort pen sensor has been tripped by the animal entering through the sort pen gate, at step 566. If so, the designated sort pen gate is closed at step 568. Finally, the identification of the animal entering the sort pen is recorded at step 570 and the processing sequence program ends for that particular animal at step 572.

[0510] FIG. 26 is the overall ECM process control program in the process control computer that controls identification and shutdown of the various equipment used in the system including the sort pen gate sensors, the measuring and processing station sensors, the station gate actuators, the tiris EID reader, the ultrasound computer, the video measurement computer, the FBS computer interface and the like. The program is indicated generally at 574.

[0511] First, the particular configuration of the feedlot management system being used is loaded into the computer at step 576, and thereafter the various computers, interfaces, actuators, sensors, sort pen gates, and the like are initialized at step 578. Next, the various parameters to be used in the system are entered at step 580 through a data entry means. Next, the program checks for user inputs at step 582, and inquires whether any stopping of the operation of the system has been requested at step 584. If a stop has been requested, the system waits for the gates to settle at step 586 and then shuts down the equipment under its control at step 588 to end the ECM process control program at step 590.

[0512] If no stop of the system has been requested, then the program updates the sensors at step 592, updates the gates at 594 and updates the measurement and processing stations at step 596. Thereafter, the program returns to the portion of the program at step 582 that checks for user inputs and the program then continues to operate for the next animal proceeding through the system.

[0513] FIG. 27 is the station initialization program 598 that conditions each measuring and processing station for the receipt of the next animal. Each station is initialized at step 600, and when completed for all stations, the station initialization program ends at step 602. To initialize each station or pen, the program inquires whether the fill sensor in that station is on, at step 604. If the fill sensor is on, the program inquires whether this is a sort pen at step 606. If not, the program then assumes that the head gate is closed and that the tail gate is closed for that particular station at step 608, and then the program returns to its start at step 600 and repeats the sequence for each of (n) stations or pens. If at any station the program detects that a fill sensor is not on, at step 604 the program proceeds to a station setup step 610 and then back to the start of the programming sequence at step 600. If at step 606 of the programming sequence the program detects that this is a sort pen being initialized, then the program proceeds to the station setup step 610 before proceeding back to the start of the programming sequence at step 600.

[0514] FIG. 28 is the flow chart for the “update stations” program 612. The first step in the program sequence is to update each station for the next animal as indicated at step 614. When each station of the total number of stations (n) has been updated, the update program for that station ends at step 616. The program resequences until all stations have been updated.

[0515] To update a station, the next step 616 of the program asks a station whether it is waiting for an animal. If it is, then it initiates the capture animal program at step 618, which will be described subsequently. After the capture animal program for a particular station has been run, the program sequences back to its start at step 614 and then proceeds to update the next station. If a particular station at sequencing step 616 of the program is not waiting for an animal, the program then asks whether an animal has been captured at step 620. If an animal has not been captured, it then asks at step 622 whether an animal has been released from the station. If an animal has been released, the program resequences to the beginning at step 614 to rerun the program for the next station. If for a particular station an animal is captured when the inquiry is made at step 620, the program next asks at step 624 whether the measurements are complete at that station. If the measurements are not complete, the program waits until the measurements are made at step 626.

[0516] Next, the program asks if the measurements have been completed at step 628 and if the answer is yes a light on the control panel is turned on at step 630 to indicate that the measurements are complete, and the program sequences back to the beginning at step 614. If the measurements are not complete, the program sequences back to the beginning and reruns until the measurements are complete and the “complete light” can be turned on.

[0517] If, at step 624 when the program inquires whether the measurements are complete and the answer is yes, the program then asks at step 632 whether the animal is ready for release. If the answer is no, the program sequences to the beginning and reruns through the sequences until the animal is ready for release. When the animal is ready for release at step 632 of the program, it then asks at step 634 whether the release button has been pushed. If it has, then the animal is released at step 636. If it has not, then the program sequences back to the beginning to rerun until the animal is released. If at step 622 of the program an animal has not been released, then the program commands that the animal be released at step 638 after which the program sequences back to the beginning to update the station for the next animal.

[0518] FIG. 29 shows the flow chart for the “station setup” computer program 640. In the first step of the programming sequence the program asks whether this is a sort pen. If it is a sort pen, the sort pen entrance gate (indicated in the flow chart as the “tail gate” at step 644 is closed to end the station setup program for the sort pen.

[0519] If the station setup program is not being run for a sort pen, then the program commands that the squeeze gate, if any, be opened at 646. Next, the program inquires at step 648 whether the station has a crack sensor. If it does, then the program commands that the head gate be cracked at step 650. Then the program commands that the tail gate be opened at step 652 to end the setup program for that particular station.

[0520] If at the sequencing step 648 the station does not have a crack sensor, then the program commands that the station head gate be closed at step 654 and then that the tail gate be opened at step 652 to end the station setup program, at which point the station is ready to receive the next animal.

[0521] FIG. 30 is the flow chart for the “capture animal” program for each station, which, like the preceding programs, is run by the process control computer. The program, indicated at 656, first inquires whether the tail gate for a station is open at step 658. If the tail gate is not open, it inquires whether the fill sensor at the station is on at step 660. If the fill sensor is not on the program sequences to a point where it asks whether the head and tail gates are closed at step 662. If the head and tail gates are not closed, the program sequences to its end at step 664 because there is no animal present to be captured.

[0522] Returning to step 660 of the programming sequence, if the fill sensor is on, the program then inquires whether the tail sensor is on at step 666. If the tail sensor is on the program then sequences to step 662 to inquire whether the head and tail gates are closed. If the head and tail gates are closed, the programs inquires whether this is a sort pen at step 668. If it is not a sort pen, the program commands that the status light on the control panel be turned on to indicate that the measuring or processing at the station is not complete, at step 670. If at step 668 it is a sort pen, then the program commands that the animal's identity be recorded at step 672.

[0523] Returning to step 666, if the tail sensor is not on but the fill sensor is on, then the program commands that the tail gate be closed at step 674. Once the tail gate is closed, the program at step 676 inquires whether there is a head catcher at the station and if so whether the head is to be caught by it.

[0524] If the station has no head catcher, then the program at step 678 inquires whether the head sensor is off. If it is not off, nothing further happens until it does go off. Then the program commands the head gate to close at step 680. When the head gate closes the program inquires whether the station has a squeeze gate and if so whether the animal is to be squeezed, at step 682. If the animal is to be squeezed, the squeeze gate is commanded to close at step 684. After the squeeze gate is closed, the program sequences through the steps previously described at 662, 668, and 672 to the end of the capture program at 664.

[0525] If at step 676 there is an indication that there is a head catcher to be operated, the program inquires at step 686 whether the head sensor is on. If it is on then the head gate is commanded to close at step 688, and the program sequences through steps 682, 684, 662, 668 and 672 as previously described.

[0526] If at step 686, the head sensor is not on, then the program sequences to step 662 to inquire whether the head and tail gates are closed.

[0527] The next program to be described is the “make measurements program, the flow diagram for which is shown in FIG. 31 and indicated generally at 690. This is the program of the process control computer that controls the operation of the computers that control the equipment for making the three basic measurements, namely a weight measurement, an external measurement via the video scanner, and an ultrasound measurement for backfat via the ultrasound machine. The program also controls the reading of the measurement data and its transmission to the FBS computer.

[0528] The first step 692 in the program is to inquire whether an animal needs to be identified through its EID tag, by asking whether there is a tiris reader. If there is a tiris reader the program inquires whether an electronic ID of the animal is still needed at step 694. If an electronic identification is needed, the program inquires whether an identity reading is ready at step 696. If the reading is ready, the program instructs the computer to read the animal's electronic identification at step 698. If at any step in the foregoing sequence, it is indicated that no electronic ID is needed or that the reading is not ready, the program proceeds to the next sequence of steps.

[0529] The sequence involves weighing, and the first step in the sequence is to inquire whether there is a scale at the station. If there is a scale at the station, the program inquires at step 708 whether a weight is required. If a weight is required the program asks if the scale reading is available at step 710. If the scale reading is available, the program instructs the computer to read the scale weight at step 712. If at any point in the foregoing weigh sequence it is indicated that a weight is not required or a weight reading is not available, the program sequences to the next series of steps for backfat measurement. The backfat steps start with an inquiry at step 708 whether there is an ultrasound machine at the station. If there is, the program inquires whether a backfat measurement is required at step 710. If a backfat measurement is required, the program commands the appropriate computer to read the ultrasound data at step 712. If a backfat measurement is not available or needed, or once the ultrasound data has been read, the program sequences to the next series of steps relating to video measurements.

[0530] The first inquiry at the next sequence of steps as indicated at step 714 is whether there is a video measurement interface at the particular station. If there is, the program inquires whether a hip-height measurement is still required at step 716. If it is, the program inquires whether the video measurements are ready to be read at step 718. If they are, a reading of the video measurements of the animal is made at step 720, and the program sequences to the next series of steps beginning at step 722. If at any point in the video measurement sequence of steps it is indicated that a measurement is not required or that the video measurements are not available to be read, the program sequences to the next series of steps.

[0531] At step 722 the program inquires whether there is an FBS computer interface at the station. If there is, the program inquires whether a sort pen is required at step 724. If one is required, the program inquires whether all measurements are completed at step 726. If all measurements are completed, then the program transmits the recorded measurement data to the FBS computer. It also requests the FBS computer to assign a sort pen to the animal at step 728. If at any point in the foregoing sequence of steps, beginning at step 722, there is no sort pen required or all measurements are not complete, the program proceeds to the end at step 730.

[0532] From the foregoing description of the “make measurements” program it will be apparent that this program can be used to control the appropriate computer and equipment at each measurement station to make the appropriate measurements, then record them and transmit the measurement data to the FBS computer, and in turn receive a sort pen assignment from the FBS computer based on such measurement data.

[0533] The next program to be described is the “release animal” program, the flow diagram of which is shown in FIG. 32 and indicated generally at 732.

[0534] The first step in the release animal programming sequence, at step 734, is to inquire whether there is an animal at the particular station. If there is no animal, the program sequences to command the head gate to open and the squeeze gate to open at step 736. Then the program sequences to inquire whether the fill sensor is off at step 738. If the fill sensor is not off, the program sequences to the end of the station release program at step 740 and the animal is not released.

[0535] If the fill sensor is off at step 738 then the program inquires whether the head sensor is off at step 742. If the head sensor is off, then the program commands the station setup program to start at step 744 and completes its sequencing at step 740. If the head sensor is not off at step 742, the program sequences to the end of the program and the animal is not released.

[0536] If at step 734 of the program sequence there is an animal in the station, the next inquiry is whether this is a sort pen, at step 736. If it is a sort pen, then the program sequences to pass the animal data to the next station at step 748 and then to turn the status lights off on the control panel at step 750. Thereafter, the program sequences to step 736 to open the squeeze and head gates to release the animal.

[0537] If at step 746 in the sequence the indication is that the station is not a sort pen then the program sequences to the next step 752 to inquire whether the next station is ready for an animal. If the answer is no, the program sequences to the end at step 740 and the animal is not released. If the answer is yes at step 752, then the animal data is passed to the next station at step 748, the status lights are turned off at step 750 and the program sequences to step 736 to release the animal.

[0538] The next program to be described, with reference to the flow diagram of FIG. 33, is the “read ultrasound data” program 754. The first step in the program sequence is to inquire whether a backfat reading is available from the ultrasound computer at step 756. If one is not available, the program sequences to the end at step 758. If a reading is available, the computer is instructed to read the backfat reading from the ultrasound at step 760. Next, the program inquires whether the backfat reading is good at step 762. If it is not, then the program commands the computer to turn on the bad reading status light on the control panel at 764 and the program sequences to the end. If the reading is good then the “good reading” status light is turned on at the control panel at step 766. Then the good reading is added to the list of backfat readings for that animal at step 768.

[0539] After the reading, the program commands the computer at step 770 to count the number of other readings that are within 0.2 inches, as indicated at step 772. When that has been done, the program sequences back to step 770 until all such readings in the list have been counted as indicated. When that is done, the program sequences to step 774 and inquires whether there are four or more close readings. If there are four or more close readings, the next step 776 is to average the close readings. Then the computer turns on the “backfat complete” status light on the control panel at step 778 and the program ends.

[0540] If at step 774 there are not four or more close readings, then the program sequences to step 780 and asks if there are eight or more readings in the list. If there are not, the program sequences to the end at 758. If there are, the program instructs the computer to clear the list and reset to start over at step 782 and then sequences to the end of the program at step 758.

[0541] The next program to be described is the FBS computer interface program 784 described with reference to the flow diagram of FIG. 34. This program operates the FBS interface indicated at 246 in FIG. 17. The first step 786 in the program is to send an initialize command to the FBS computer. The next step 788 in the program is to read a command from the FBS computer. The next 790 step in the program is to inquire whether an animal data request has been received from the FBS computer. If not, the program sequences back to step 788 to await a command from the FBS computer. If there is no command from the FBS computer or no response, the program sequences back to the beginning to send an initialize command to the FBS computer.

[0542] If at step 790 an animal data request is received from the FBS computer, an acknowledgement is sent to the FBS computer at step 792. Next, the program inquires whether data from the next animal is collected yet, at step 794. If the data has not yet been collected, the program returns to step 794 to await the collection of data. When data for the next animal has been collected, the program sequences to step 796 and sends the animal data to the FBS computer. Next, at step 798 the program waits to read a response from the FBS computer. Then, the program awaits receipt of an animal data acknowledgement from the FBS computer at step 800. If not received, the program requests the FBS computer to resend an acknowledgement. Upon an initialize command or no response from the FBS computer, the program sequences back to the initial step 786.

[0543] If the program receives an acknowledgement from the FBS computer that the animal data was received, the program next reads the sort pen assignment received from the FBS computer at step 802. Next, at step 804, the program inquires whether the sort pen assignment was received from the FBS computer. At this point if there is an initialize command from the FBS computer or no sort pen assignment from the FBS computer, the program sequences back to the initial step 786.

[0544] If there is a sort pen assignment received from the FBS computer, the program sends a sort pen acknowledgement to the FBS computer at step 806. Then, at step 808 the program commands the computer to update the current animal with its assigned sort pen number, in other words, to correlate the new sort pen assignment with the identified animal. The program then returns to step 788, awaiting a command from the FBS computer.

[0545] Finally, there is a program for loading the ECM (cattle management system) station configuration information into the process control computer. This program is diagrammed in FIG. 35 and indicated generally at 810. In the first step of its sequence the program inquires whether this is the end of the configuration file, at step 812. If the answer is yes, then the program sequences to step 814 to check for any missing definitions. Then the load configuration program ends at step 816. If the configuration file is not fully loaded, then from step 812 the program sequences to read the element definition from the configuration file at step 818. Then the program determines the definition type at step 820 and breaks the definition into its components at step 822 and creates the object specified by the definition at step 824 before sequencing back to the beginning of the load configuration program.

[0546] From the foregoing it will be appreciated that the disclosed computerized cattle management system and method provides a highly flexible system and method for measuring, sorting and processing animals, either on a group basis or an individual basis or in a combination of group and individual basis. It furthermore proves a means and method for projecting, on an individual animal basis, when that animal will be ready to be shipped from the feedlot to the packing plant for slaughter and what that animal's optimum finish weight will be. The system also provides a means and method whereby the costs of maintaining animals in the feedlot can be determined on an individual animal basis so that such costs, on an individual animal basis, can be assessed to the animal's owners, thereby providing a highly efficient cost management tool.

[0547] With the management system, no longer is it necessary to treat a group of animals received in a feedlot as a group throughout its period of stay in the feedlot. Instead, different groups of animals as received in a feedlot can be mixed with other groups regardless of ownership, based on management criteria such as animal type, DTF, OEW or other factors. Since each animal can be identified electronically at any time and at any place during its stay in the feedlot, with its ownership easily determined, it can be grouped with other animals with similar physical characteristics or OED's rather than being kept in a common ownership group while in the feedlot. Similarly, when animals are ready for slaughter, they can be sent to the packing plant without regard to ownership because their EID tags will identify them at packing plant as to ownership and thus costs and proceeds can be properly assessed and credited without regard to group.

[0548] From the foregoing, it should be apparent that a particular animal may be in one group or lot when it arrives in a feedlot, may be moved to a different group within a feed pen during the feeding period, and may be sorted into a marketing group different than its pen feeding group when it is finally ready for shipment to the packing plant. All of this is made possible by the ability to electronically identify each animal by ownership and physical characteristics and costs at any time, irrespective of the group it happens to be in at any given time.
