IL278965A - A system and method for tracing members of an animal population - Google Patents

Description

FIELD AND BACKGROUND OF THE INVENTION It is to be noted that in some cases, the entry reader and the exit reader can be the same reader. In such cases, the single reader used to identify the animals when they are arriving and exiting a given location can optionally operate in a first operation mode for identifying arriving animals and a second operation mode for identifying departures.

Alternatively, a computerized system can be used in order to discriminate between entries and exits of the animals, using programmed logic. It is to be further noted that in some cases only one of the animal entry time or exit time is tracked (or alternatively instead of the animal entry time or the animal exit time, an indication of an arbitrary time between arrival and departure from each location can be stored, which can also be used to indicate that the animal was processed at such location), and in such cases a single device reader can be used to acquire only a single reading of an animal passing through the respective location. Such configuration however, by itself, may not enable determining a stay time of the animal at the respective location, which is useful information. That said, using a single reader along with an additional sensor (e.g. a video camera) can complement the information obtained by the reader with additional information, such as whether the identified animal is arriving at, or departing from, the location.

Looking at Location N, it can be seen that within the location a virtual station exists, namely Virtual Station A. A virtual station is a station in which all, or some, of the animals are required to pass while staying at a given location. Virtual Station A is a station in which all, or some, of the animals that arrive at location N are required to pass as part of their processing. For example, in some cases, any animal that arrives at Location N has to be vaccinated. The vaccination can be provided at Virtual Station A, within Location N, without the need to move the animal to another location for vaccination. In such cases, the animals can be identified by Virtual Station A Reader, which is configured to uniquely identify the animals that that are being processed at Virtual Station A. Virtual Station A Reader can be a manual identification device reader operated by a human operator, such as a veterinarian for example.

When an animal is processed or arrives at Virtual Station A, it is identified using Virtual Station A reader (e.g. by reading an ID tag attached to the animals, or using a - 18 - visual identification, or using any other system and/or identification method). When the Animals have been identified upon being processed at Virtual Station A, a suitable indication, along with the processing time is stored on the data repository (as further detailed herein). Those records that are stored on the data repository when an animal is processed at a virtual virtual station re Having described the general process of data collection, attention is now drawn to Fig. 2. Fig. 2 is a block diagram schematically illustrating one example of a tracing system for tracing members of an animal population, in accordance with the presently disclosed subject matter.

Tracing system 100 comprises a network interface 110 (e.g. a network card, a WiFi client, a LiFi client, 3G/4G client, or any other component), enabling tracing system 100 to communicate over a network with external systems from which it obtains information of animal movements and/or animal locations. The external systems can be the entry/exit/virtual station readers themselves, or any other intermediate system(s) that obtain the information about the progress of the animals in their processing (e.g. computerized systems that manage each of the locations and directly communicate with the entry/exit readers).

Tracing system 100 further comprises, or is otherwise associated with, a data repository 120 (e.g. a database, a storage system, a memory including Read Only Memory ROM, Random Access Memory RAM, or any other type of memory, etc.) configured to store data, optionally including, inter alia, animal location change records and/or animal virtual station records. Each location change record is associated with a respective distinct animal and can include an indication of a location into which the animal entered or from which the animal exited or in which the animal was processed, and an indication of a corresponding time for either an exit, entrance or processing. Data repository 120 can be further configured to enable retrieval and/or update and/or deletion of the stored data.

It is to be noted that in some cases, data repository 120 can be distributed, while the tracing system 100 has access to the information stored thereon, e.g. via a wired or wireless network to which tracing system 100 is able to connect (utilizing its network interface 110).

Tracing system 100 further comprises a processing circuitry 130. Processing circuitry 130 can be one or more processing units (e.g. central processing units), microprocessors, microcontrollers (e.g. microcontroller units (MCUs)) or any other - 19 - computing devices or modules, including multiple and/or parallel and/or distributed processing units, which are adapted to independently or cooperatively process data for controlling relevant tracing system 100 resources and for enabling operations related to tracing Processing circuitry 130 can comprises one or more of the following modules: a location change tracking module 140, a tracing module 150, a virtual station tracking module 160 and a compliance module 170.

Location change tracking module 140, can be configured to track location change of animal during their processing (optionally in real-time or near-real time), as further detailed herein, inter alia with reference to Fig. 3.

Tracing module 150 is configured to perform a process for tracing animals, as further detailed herein, inter alia with reference to Fig. 4.

Virtual station tracking module 160 is configured to perform a process for tracking visits of animals at virtual stations, as further detailed herein, inter alia with reference to Fig. 7.

Compliance module 170 is configured to perform one or more processes for checking compliance of animals with various compliance requirements, as further detailed herein, inter alia with reference to Figs. 5, 6 and 8. Some exemplary compliance requirements include: number of days in quarantine, getting a vaccine/medication, getting a vaccine/medication within a certain period of time from a triggering event, group size, average number of individual animals meeting certain criteria, animal weight thresholds, etc.

Turning to Fig. 3, there is shown a flowchart illustrating one example of a sequence of operations carried out for tracking location changes of animals, in accordance with the presently disclosed subject matter.

In accordance with the presently disclosed subject matter, tracing system 100 can be configured to perform location change tracking process 200 (optionally in real-time or near-real time), e.g. using location change tracking module 140. For this purpose, tracing system 100 is configured to obtain a reading of an identification device attached to, and uniquely identifying, a given member of an animal population to be tracked, the reading acquired by an identification device reader located at a respective given location (being a distinct physically separate location, distinct and physically separate from other locations) (block 210). It is to be noted that, as indicated herein, in some cases the animal can be - 20 - identified using other identification systems and/or methods that enable uniquely identifying the animals of the animal population.

Upon obtaining the reading at block 210, tracing system 100 inserts a location change record to the data repository 120, indicating that the given member arrived at, or departed from, the given location (block 220). The location change record includes an indication of an arrival time of the given member to the given location or the departure time of the given member from the given location, thereby enabling tracing the members throughout the process. It is to be noted that the reading time, indicative of the arrival/departure time of the animal to/from the given location, can accompany the reading obtained at block 210, optionally along with additional information.

As indicated herein, with reference to Fig. 1, each animal is identified at least once in each location in which it is required to pass as part of its processing. The animal can be identified (a) upon arrival at a given location in which it is to be processed (according to a processing need thereof), or (b) upon exiting the given location in which it is to be processed. In some cases, the animal is identified both upon arrival to the given location in which it is to be processed and upon exiting the given location in which it is to be processed, and in further embodiments, the animal may be identified during its stay in a given location.

Accordingly, in certain embodiments, when an animal arrives at the given location, it is identified (e.g. using an entry reader associated with the given location), and a location change record can be generated, indicating that the animal arrived at the given location, and indicating its arrival time at the given location. Similarly, when an animal exits the given location, it is identified (e.g. using an exit reader associated with the given location), and a location change record can be generated, indicating that the animal exited the given location and indicating its exit time from the location.

It is to be noted that in some cases an animal is identified only once in one or more of the locations in which it is processed, and in such cases, a single location change record is stored indicating that it passed through the given location at a given passage time in which it was identified by the respective reader.

It is to be noted, with reference to Fig. 3, that some of the blocks can be integrated into a consolidated block or can be broken down to a few blocks and/or other blocks may be added. It should be also noted that whilst the flow diagram is described also with - 21 - reference to the system elements that realizes them, this is by no means binding, and the blocks can be performed by elements other than those described herein.

Attention is now drawn to Fig. 4, a flowchart illustrating one example of a sequence of operations carried out for tracing animals, in accordance with the presently disclosed subject matter.

In accordance with the presently disclosed subject matter, tracing system 100 can be configured to perform an animal tracing process 300 (optionally in real-time or near- real time), e.g. using tracing module 150. For this purpose, tracing system 100 is configured to obtain a population indication request, requesting indications of members of the tracked animal population that meet a criterion (block 310) and to analyze the data repository to identify the members that meet the criterion (block 320).

The information of the location changes of the animals in the animal population as obtained by the location change tracking process 200 enables tracking animal progress throughout the animal processing, as well as tracking interactions between animals (e.g. by determining which animals were located at a given location and which other animals are also located there at the same time).

The criterion mentioned in block 310 can depend on a location of the members.

For example, the criterion can be a location from which the members originate or in which the members passed, at any time, or during a given time window.

Looking at a specific example, a user of the tracing system 100 may be interested in locating all members of the animal population that originate from Location A. In such case, the tracing system 100 will analyze the data repository 120 to identify which members of the animal population started their processing in Location A.

Looking at another example, a user of the tracing system 100 may be interested in locating all members of the animal population that passed through Location C. In such case, the tracing system 100 will analyze the data repository 120 to identify which members of the animal population passed through Location C. In some cases, the user may be interested in locating all members of the animal population that passed through Location C during a certain time period (for example a certain year). In such case, the tracing system 100 will analyze the data repository 120 to identify which members of the animal population passed through Location C during 2020.

Clearly the criterion can be much more granular. For example, a user of the tracing system 100 may be interested in locating all members of the animal population that - 22 - originate from Location A, passed through Location C, and arrived at Location N during the last ten days. In such case, the tracing system 100 will analyze the data repository 120 to identify which members of the animal population that originate from Location A, passed through Location C, and arrived at Location N during the last ten days. The tracing system 100 can optionally provide an indication as to the current location of such animals, optionally in real-time or near-real-time.

In even more complicated cases, the criterion can also refer to virtual station visits of the members of the animal population determined according to virtual station records (as further detailed with reference to Fig. 7). For example, a user of the tracing system 100 may be interested in identifying all the animal that are currently located at Location N, that passed through Location B and did not pass through virtual station A. For example, assuming that according to regulations that apply at Location N, animals that pass- through Location B (which can be a certain country) must be vaccinated with a specific vaccine. Accordingly, the tracing system 100 has ability to identify those animals that arrived at Location N after passing through Location B and did not receive vaccine within a certain time window since their arrival.

In some cases, the criterion mentioned in block 310 can depend on the location of the members with respect to one or more indicated members of the members. For example, a user of the tracing system 100 may be interested in locating all members of the animal population that have been located with the indicated members (being one or more specific animals identified using their unique identifier).

In a specific example, the indicated members are indicated as being sick or as being directly or indirectly associated with a sick member of the animals (members that have been located with a sick animal in one of the locations, members that have been located with other members that were located with a sick animal in one of the locations, etc.). Clearly, having the ability to identify all members of the animal population that may have been affected by a sick animal is crucial and may prevent a need to terminate an entire animal population. Assuming that a given animal was identified as sick with a viral disease, having information of its locations and the locations of the other members of the animal population enables identifying those animals of the animal population that may have been infected by the sick animal. Infection can be direct (by the given animal directly infecting animals that were located with the sick animal in a given location), or indirect - 23 - (by the given animal infecting another animal that later infects another animal, and so on).

In some cases, the criterion can be a shipment identifier, identifying a specific shipment of a group of members of the animal population between locations. In such cases, a user of the tracing system 100 may be interested in identifying the locations of all members of the animal population that have been shipped in the shipment identified by the shipment identifier.

Tracing system 100 can be further configured to provide an indication of the members that meet the criterion (block 330). Such indication can be provided via any output device, such as: a display or indication mechanisms attached to the animal population (e.g. each animal may have an indication mechanism, such as a light source, a speaker, etc., and the indication mechanisms of the members that meet the criterion may be activated to identify the members that meet the criteria).

It is to be noted, with reference to Fig. 4, that some of the blocks can be integrated into a consolidated block or can be broken down to a few blocks and/or other blocks may be added. It should be also noted that whilst the flow diagram is described also with reference to the system elements that realizes them, this is by no means binding, and the blocks can be performed by elements other than those described herein.

Attention is drawn to Fig. 5, a flowchart illustrating one example of a sequence of operations carried out for checking compliance of animals with compliance goals, in accordance with the presently disclosed subject matter.

In accordance with the presently disclosed subject matter, tracing system 100 can be configured to perform an animal compliance check process 400, e.g. using compliance module 170. For this purpose, tracing system 100 is configured to obtain a data repository 120 comprising a plurality of location change records associated with a plurality of animals of an animal population (block 410).

Tracing system 100 is further configured to analyze the data repository 120 to identify non-compliant members of the animal population that fail to meet one or more compliance goals (block 420). The compliance goals can include definitions of arrival time goals of arriving at one or more of the locations, departure time goals of departing from one or more of the locations, stay times in one or more of the locations, required passages at one or more of the locations, vaccination/medication requirements (optionally including timing requirements such as getting the vaccination/medication within a certain - 24 - period of time from a triggering event such as arrival time), health requirements, quarantine requirements (e.g. number of days in quarantine), population size (e.g. number of animals within a population or a sub-group of animals of the animal population), average number of individual animals meeting certain criteria, animal weight thresholds, etc.

Some example of non-compliant members: (a) the arrival time indicated by one or more of the location change records associated with the non-compliant members fails to meet an arrival time criterion (indicating that the non-compliant members failed to arrive at a given location on time), (b) the departure time indicated by one or more of the location change records associated with the non-compliant members fails to meet a departure time criterion (indicating that the non-compliant members failed to depart from a given location on time), (c) a stay time lapsing between the arrival time of any given non-compliant member of the non-compliant members to a given distinct physically separate location of the distinct physically separate locations and the departure time of the given non-compliant member from the given distinct physically separate location as indicated by the location change records associated with non-compliant members fails to meet a stay time criterion (indicating that the non-compliant members over stayed or under stayed at a given location), or (d) the one or more of the location change records associated with the non-compliant members indicate that the non-compliant members skipped one or more of the plurality of physically separate locations (indicating that the non-compliant members did not pass through a given location that they were required to pass through).

In some cases, regulatory requirements define one or more of (a) the arrival time criterion, (b) the departure time criterion, or (c) the stay time criterion. In some cases, the tracing system 100 enables configuring regulatory requirements (e.g. by a user of the system).

It is to be noted that the regulatory requirements can be location specific, so that the regulatory requirements in a first location (a first distinct physically separate location) of a plurality of distinct physically separate locations is different than the regulatory requirements in a second location (a second distinct physically separate location) of the distinct physically separate locations.

In some cases, the regulatory requirements can be determined according to a destination location of the physically separate locations, being a destination location of - 25 - the animal population. Assuming for example, that a first group of animals of an animal population is designated to a first country, and a second group of animals of the animal population is designated to a second country, the regulatory requirements that the first group of animals are subject to are defined according to a regulator of the first country, whereas the regulatory requirements that the second group of animals are subject to are defined according to a regulator of the second country.

In some cases, the regulatory requirements can be determined according to a type of the animal population. Assuming for example, that a first group of animals of an animal population include cows for slaughter, and a second group of animals of the animal population include dairy cows, the regulatory requirements that the first group of animals are subject to can be different than the regulatory requirements that the second group of animals are subject to.

It is to be noted, with reference to Fig. 5, that some of the blocks can be integrated into a consolidated block or can be broken down to a few blocks and/or other blocks may be added. It should be also noted that whilst the flow diagram is described also with reference to the system elements that realizes them, this is by no means binding, and the blocks can be performed by elements other than those described herein.

Fig. 6 is a flowchart illustrating one example of a sequence of operations carried out for checking compliance of an animal population with compliance goals, in accordance with the presently disclosed subject matter.

In accordance with the presently disclosed subject matter, tracing system 100 can be configured to perform an animal population compliance check process 500, e.g. using compliance module 170. For this purpose, tracing system 100 is configured to obtain a data repository 120 comprising a plurality of location change records associated with a plurality of animals of an animal population (block 510).

Tracing system 100 is further configured to analyze the data repository 120 to check compliance of a subset of the animal population with a population compliance goal (block 520). It is to be noted that compliance can be measured on a group level (e.g. a subset of the animal population that meet a certain criterion (located at a certain location, originate from a certain location, designated to a certain location, etc.), the entire animal population, etc.), instead of, or in addition to, compliance measurements on an individual animal level. In such cases, it is desirable to check if a group of animals of the animal population met compliance goals. For example, a certain compliance goal may indicate - 26 - that at least 20% of the animal population on Location N are required to be animals that originate from Location A. Tracing system 100 can continuously monitor the animal population in Location A in order to verify that the goal is met. In those cases that the goal is not met tracing system 100 can be configured, for example, to provide a suitable notification to a user thereof.

It is to be noted, with reference to Fig. 6, that some of the blocks can be integrated into a consolidated block or can be broken down to a few blocks and/or other blocks may be added. It should be also noted that whilst the flow diagram is described also with reference to the system elements that realizes them, this is by no means binding, and the blocks can be performed by elements other than those described herein.

Fig. 7 is a flowchart illustrating one example of a sequence of operations carried out for tracking visits of animals at virtual stations, in accordance with the presently disclosed subject matter.

In accordance with the presently disclosed subject matter, tracing system 100 can be configured to perform an animal virtual stations visits tracking process 600, e.g. using location change tracking module 140. For this purpose, tracing system 100 is configured to obtain a virtual station reading of an identification device attached to, and uniquely identifying a virtual station visiting member of the animal population, visiting the virtual station (block 610). It is to be noted that, as indicated herein, in some cases the animal can be identified using other identification systems and/or methods that enable uniquely identifying the animals of the animal population.

As indicated herein, a virtual station is a station in which all, or some, of the animals are required to pass while staying at a given location. Looking at Fig. 1 for example, Virtual Station A is a station in which all, or some, of the animals that arrive at location N are required to pass as part of their processing. For example, in some cases, any animal that arrives at Location N has to be vaccinated. The vaccination can be provided at Virtual Station A, within Location N, without the need to move the animal to another location for vaccination. In such cases, the animals can be identified by Virtual Station A Reader, which is configured to uniquely identify the animals that that are being processed at Virtual Station A. Virtual Station A Reader can be a manual identification device reader operated by a human operator, such as a veterinarian for example.

Upon each of the animals arriving at, or being processed at, Virtual Station A, it is identified using Virtual Station A reader (e.g. by reading an ID tag attached to the - 27 - animals, or using a visual identification, or using any other system and/or identification method).

Tracing system 100 is further configured to insert a virtual station record to the data repository, indicating that the virtual station visiting member visited the virtual station (block 620). The virtual station record can include an indication of a time of visit of the respective animal at the virtual station thereby enabling tracing animal visits at the virtual stations. It is to be noted that the reading time, indicative of the visit time of the animal at the virtual station, can accompany the reading obtained at block 610, optionally along with additional information.

In some cases, the virtual station can be a treatment station (e.g. a station in which animals gets: vaccinated, medicated, x-rayed, scanned, inseminated, or gets any vet operation, nutritionist operation, farmer operation, regulatory operation, or commercial operation). In such cases, the virtual station visiting member (the animal that visits the virtual station) receives treatment at the treatment station, and the virtual station record indicates that the treatment receiving member received the treatment. In such cases, the virtual station reading can be obtained by a treatment provider (e.g. a veterinarian) located at the treatment station. In some cases, the virtual station reading can be obtained by a treatment provider using a manual identification device reader capable of identifying the animal receiving the treatment (e.g. by reading an identification tag attached thereto, or in any other manner).

It is to be noted, with reference to Fig. 7, that some of the blocks can be integrated into a consolidated block or can be broken down to a few blocks and/or other blocks may be added. It should be also noted that whilst the flow diagram is described also with reference to the system elements that realizes them, this is by no means binding, and the blocks can be performed by elements other than those described herein.

Fig. 8 is a flowchart illustrating one example of a sequence of operations carried out for checking compliance of animals with virtual stations compliance goals, in accordance with the presently disclosed subject matter.

In accordance with the presently disclosed subject matter, tracing system 100 can be configured to perform an animal virtual station compliance process 700, e.g. using compliance module 170. For this purpose, tracing system 100 is configured to obtain a data repository 120 comprising a plurality of virtual station records associated with a plurality of animals of an animal population (block 710). - 28 - Tracing system 100 is further configured to analyze the data repository 120 to identify non-treated members of the animal population, being the members that did not receive the treatment at the treatment station (block 720). As indicated herein, a virtual station can be a treatment station. In such cases, the virtual station records that have been acquired via process 600, can be used in order to identify animals of the animal population that did not receive treatment at a treatment station. t.

It is to be noted that in some cases, the non-treated members are the members of the animal population that did not receive the treatment at the treatment station at required times (e.g. before moving to a subsequent location (e.g. a subsequent physically separate location of a plurality of physically separate locations) subsequent to the treatment station).

In some cases, tracing system 100 can be further configured to analyze the data repository 120 to identify the members that have been located at one or more of the physically separate locations with any of the non-treated members. . In some cases, tracing system 100 can be further configured to provide a suitable notification enabling identification of such non-treated members to a user thereof.

Tracing system 100 can be further configured to analyze the data repository 120 to check compliance of a subset of the animal population with a population compliance goal associated with the treatment. It is to be noted that compliance can be measured on a group level, instead of, or in addition to, compliance measurements on an individual animal level. In such cases, it is desirable to check if a group of animals of the animal population met compliance goals. For example, a certain compliance goal may indicate that at least 75% of the animals that arrive at Location N must be vaccinated within 5 hours of arrival to Location N. Tracing system 100 can continuously monitor the animal population in Location N in order to verify that the goal is met. In those cases that the goal is not met tracing system 100 can be configured, for example, to provide a suitable notification to a user thereof.

It is to be noted, with reference to Fig. 8, that some of the blocks can be integrated into a consolidated block or can be broken down to a few blocks and/or other blocks may be added. It should be also noted that whilst the flow diagram is described also with reference to the system elements that realizes them, this is by no means binding, and the blocks can be performed by elements other than those described herein. - 29 - It is to be understood that the presently disclosed subject matter is not limited in its application to the details set forth in the description contained herein or illustrated in the drawings.

BACKGROUND 5 In many cases, animals are moved or transferred between various physically separate locations, whether on the same premise (e.g. between separate areas within a farm) or between premises (e.g. between farms). In some cases, the animals are moved between stations such as saleyards, processing plants, quarantine areas, slaughter houses, etc. In some cases, part of the stations may be located in different countries which requires 10 the animals to be shipped between such locations (e.g. via sea, air or land). In many cases, various regulations exist that define various requirements that relate to animals that are being moved or transferred. Such regulations may vary between different states or countries, different animal types, different intended usages of the animal, etc. In order to determine compliance with the regulatory requirements having knowledge of the 15 locations over time is a prerequisite. In addition, in many cases it is desirable to have the ability to determine physical encounters between animals based on their locations. This may be desirable for example in order to break down a chain of infection. In such case, when a certain animal is identified as sick, having the knowledge of those animals that may have been infected 20 from it is valuable. Such knowledge may prevent the need of terminating an entire animal population (e.g. all animal on a certain farm, all animal in a certain shipment, etc.). In addition, such knowledge can save on treatment and vaccination costs (e.g. by improving vaccination records, or by preventing spreading of diseases thereby reducing needed treatments), enable faster and more accurate tracking of disease origins (e.g. by enabling 25 identifying shipments and/or individual animals and associating those with countries of for study purposes). - 2 - There is thus a real need in the art for a new system and method for tracing members of an animal population.

In certain embodiments, the locations may be physically separate, so that animals that are located at a given location cannot freely move between different locations in accordance with their own free will. Movement of animals between locations may be a controlled process, - 13 - for example a process that can be controlled by humans and/or machinery (e.g. smart gates that can be controlled by a suitable gate control device such as a computer). Moving an animal includes moving the animal by making it walk between different locations (e.g. between different parts of a farm, noting that the different parts are physically separate 5 and the animals cannot freely move between them), or transferring it between locations (e.g. between farms, domestically or internationally) via a transportation vehicle by land (e.g. using trucks or other suitable vehicles), air e.g. (using airplanes) or sea (e.g. using ships). The animals are moved between the locations as part of a process. The process 10 can begin at animal birth, or at any later time (e.g. after the animal is tagged by attaching an Electronic Identification (EID) tag that uniquely identified the animal to the animal, or upon arrival of the animal to a given location of the physically separate location in which it is identified and entered into the for tracing members of an animal population as further detailed herein). The process can end when the animal arrives at a certain location 15 following which there is no need to continue to trace the animal (e.g. slaughter). During the process, animal movements or transferers between the locations are tracked and recorded for various purposes as further detailed herein. It is to be noted that various transportation means can also be locations. For example, a transportation means (e.g. a ship, a truck, an airplane, a trailer, etc.) used to 20 transport animals between locations can be regarded as a location itself. Further in the illustration, a certain animal population is shown to be present in location A. Although the animal 10 in the illustration is illustrated as a sheep, it is by no means limiting, and the animal 10 can be any other animal (e.g. other types of cattle, pets, fish, livestock, etc.), or a combination of various types of animals. The animal population 25 includes a plurality of animals, marked in the illustration as (a) Animal A1, ..., Animal N1 (N1 being an integer) According to the illustration, the animal processing begins at Location A, however this is by no means limiting, and the animal processing can begin at another location, or at a plurality of additional or 30 alternative locations. In accordance with the illustration shown in Fig. 1, a first group of animals ( ) is moved to location B, a second group of animals - 14 - It is to be noted that although in the illustration all animals are transferred from Location A to other locations, this is by no means limiting, and some of the animals can remain at Location A and not be moved therefrom to another location. It is to be further noted that in some cases some of the 5 animal that are shown to be located at Location A may originate from other locations from which they have been transferred to Location A. It is to be still further noted that in some cases, although not shown in the illustration, additional animals may be present at Locations B, C and D other than the animals that have been transferred thereto from Location A as shown by the illustration. Such additional animals may originate from 10 Location A, or from any other location. Looking further at the illustration, it can be appreciated that (a) the animals that have been moved fro are then moved from Location B to Location N, and (b) the animals that have been moved 15 Location C to Location N. It is to be noted that although the illustration shows that the animals are moved directly from Location B to Location N, or from Location C to Location N (i.e. without passing through intermediate locations), this is by no means limiting and the animals can pass through intermediary locations between Locations B or C and Location N. 20 In order to enable tracking animals between the locations as part of their processing (optionally in real-time or near-real time, e.g. in very short intervals of times, close to instantaneous, or within up to a few seconds), it is required to have the ability to identify them at least once within the location. For example, each animal can be identified upon arrival at each location and/or upon departure from each location and/or at any given 25 time between arrival and departure from each location. In a certain example, animals are identified upon arrival and upon departure from each location. In such case, each animal that enters a given location has to be identified, and its entry into the given location has to be recorded. Similarly, each animal that leaves a given location has to be identified, and its departure from the given location has to be 30 recorded. For this purpose, each of the physically separate locations includes a respective entry reader and exit reader. The entry readers are configured to identify animals that are entering the respective location, and the exit readers are configured to identify animals that are exiting the respective location. Looking at the illustration: (a) LA entry reader is - 15 - the entry reader associated with Location A and LA exit reader is the exit reader associated with Location A, (B) LB entry reader is the entry reader associated with Location B and LB exit reader is the exit reader associated with Location B, (c) LC entry reader is the entry reader associated with Location C and LC exit reader is the exit reader 5 associated with Location C, (d) LD entry reader is the entry reader associated with Location D and LD exit reader is the exit reader associated with Location D, entry reader is the entry reader associated with Location N and LN exit reader is the exit reader associated with Location N. Each of the entry readers is configured to uniquely identify each animal that enters 10 the respective location, and each of the exit readers is configured to uniquely identify each animal that exists the respective location. It is to be noted that the entry readers and/or the exit readers can be manual readers (operated by a user), stationary readers (e.g. monitoring passage of animal through a gate), autonomously driven readers (e.g. carried by autonomous drones), readers incorporated into a mobile device, computer, etc. 15 For this purpose, in some cases, the animals can have an identification (ID) device (such as, but not limited to, an ID tag such as an EID tag) attached thereto (not shown). The ID device can be a tag that uniquely identifies the animal to which it is attached. However, the ID device may alternatively be another type of device used to identify the animal by any of the methods or systems described herein (including electronic 20 identification, visual identification, camera-based identification, facial or body part recognition, barcode, identification marks, etc.). When read by suitable reading device (e.g. any of the entry readers and/or exit readers), the ID device returns a reading that includes at least a unique animal identifier, uniquely identifying the animal to which it is attached. As discussed, each animal can be identified using various 25 systems/devices/methods/techniques, including an ID tag, identification marks (e.g. digits, letters, symbols, or any combination thereof, etc.), readable barcodes, facial (or other body parts) recognition, etc. In other cases, all, or part of the animals can be identified without having an ID device attached thereto. One example is visual identification (e.g. facial, or other body 30 parts, recognition). In such cases, the reading devices can be visual reading device such as a camera that acquires images based on which the animals are identified. It is to be noted that in some cases, one or more of the identification methods may be passive identification methods, such as passive tags. For example, the tags can be a - 16 - printing of a certain identifier on the animal to be identified, or they can be stickers of a certain visual identifier attached to the animal to be identified, or they can be markings painted on the animal to be identified. In such cases, where the tags are visually identifiable (e.g. barcodes), the respective tag reading device can be, for example, a 5 camera capable of acquiring images in the spectrum of the visual tags. Returning to the illustration, it is to be noted that the animals are tracked during their processing (optionally in real-time or near-real time). All of the animals that are shown to be located at Location A have been identified upon entering Location A using the LA entry reader (e.g. by reading an ID tag attached to the animals, or using a visual 10 identification, or using any other system and/or identification method). In the specific non-limiting example in which the animals are identified both upon arrival to and upon departure from each location: (a) when the Animals have been identified upon entry to Location A, an indication of their entry into Location A, along with their respective entry time of entering Location A is stored on a data repository (as further detailed herein), and 15 (b) upon each of the animals exiting Location A, it is identified using LA exit reader (e.g. by reading an ID tag attached to the animals, or using a visual identification, or using any other system and/or identification method), an indication of their exit of Location A, along with their respective exit time of exiting Location A is stored on the data repository (as further detailed herein). A similar process occurs at each of the locations: 20 When animals arrive at location B, they are identified using LB entry reader, and their entry, including the entry time is recorded in the data repository. When animals exit location B, they are identified using LB exit reader, and their exit, including the exit time is recorded in the data repository. When animals arrive at location C, they are identified using LC entry reader, and 25 their entry, including the entry time is recorded in the data repository. When animals exit location C, they are identified using LC exit reader, and their exit, including the exit time is recorded in the data repository. When animals arrive at location D, they are identified using LD entry reader, and their entry, including the entry time is recorded in the data repository. When animals 30 exit location D, they are identified using LD exit reader, and their exit, including the exit time is recorded in the data repository. When animals arrive at location N, they are identified using LN entry reader, and their entry, including the entry time is recorded in the data repository. When animals - 17 - exit location N, they are identified using LN exit reader, and their exit, including the exit time is recorded in the data repository. Those records that are stored on the data repository when an animal enters or
