Description

[Technical Field]

[0001] The present invention relates to a system for managing information on abnormal chickens. [Background technology]

[0002] In recent years, high-density large-scale poultry farming has become common, with some chicken houses housing more than 100,000 chickens. Statistically, in a farm with 100,000 chickens, approximately 20 chickens die every day. Causes of these deaths include stress, fighting between chickens (such as pecking at the rear), chickens getting caught in feeders, and equipment problems such as malfunctioning drinking fountains or ventilation equipment. Chickens can also die from avian influenza, gastrointestinal diseases, respiratory diseases, etc.

[0003] On the other hand, as shown in Non-Patent Document 1, workers are recommended to patrol the poultry house daily to find dead chickens, inspect equipment such as feeders and water dispensers, and observe the health of the chickens. If dead chickens are found, they must be removed from their cages and disposed of to prevent the spread of disease and putrefaction. The number of dead chickens found and the location of the deaths are recorded in a paper ledger for management purposes. In some cases, workers enter the information into a computer after returning to the office. [Prior art documents] [Non-patent literature]

[0004] [Non-Patent Document 1] Ministry of Agriculture, Forestry and Fisheries Livestock Bureau "Technical Guidelines for Raising and Managing Layer Hens" July 26, 2023, Livestock No. 1066 Summary of the Invention [Problem to be solved by the invention]

[0005] The present inventors are considering how to estimate the cause of chicken death and address the cause of death early by effectively utilizing information collected during patrols, such as the number and location of dead and weak chickens. In particular, if it can be determined that the cause of chicken death or weakness is highly pathogenic avian influenza, effective countermeasures to prevent the spread of highly pathogenic avian influenza, which has become a problem in recent years, can be implemented early in the infection process. As a result, the damage caused by highly pathogenic avian influenza can be minimized, with immeasurable economic benefits.

[0006] In addition, the "Guidelines for the Prevention of Specific Livestock Infectious Diseases Concerning Highly Pathogenic Avian Influenza and Low Pathogenic Avian Influenza" issued by the Minister of Agriculture, Forestry and Fisheries on July 1, 2020 (partially revised on October 31, 2024) stipulates that poultry owners, veterinarians, etc. must report to the Animal Health Division if the daily poultry mortality rate is more than twice the average poultry mortality rate for the target period (21 days prior to that day).

[0007] Therefore, an object of the present invention is to provide an abnormal chicken information management system that estimates the cause of occurrence of abnormal chickens, including dead chickens. [Means for solving the problem]

[0008] In other words, the abnormal chicken information management system of the present invention is an abnormal chicken information management system for a chicken coop that houses laying hens in each of specified rearing areas, and is characterized by comprising an abnormal chicken information recording unit that records abnormal chicken information in chronological order, including at least two-dimensional or three-dimensional location information and the number of abnormal chickens in the chicken coop in the area where abnormal chickens occur, and an occurrence cause estimation unit that estimates the cause of the occurrence of abnormal chickens based on information on the time-dependent changes in the area where abnormal chickens occur and / or the time-dependent changes in the number of abnormal chickens obtained from the abnormal chicken information recorded in the abnormal chicken information recording unit.

[0009] With this abnormal chicken information management system, it is possible to accurately estimate the cause of abnormal chicken occurrence by focusing on the time-dependent changes in areas where abnormal chickens are occurring and / or the time-dependent changes in the number of abnormal chickens. Note that abnormal chickens include dead chickens (dead chickens), weak chickens, etc.

[0010] For example, if the number of dead chickens suddenly increases 24 hours after the initial outbreak, and if the increase is in the direction of ventilation in the chicken coop, it can be assumed that the cause of the dead chickens is a highly virulent infectious disease, such as highly virulent avian influenza. Furthermore, if the number of dead chickens is increasing in the direction of ventilation in the chicken coop, but the number of dead chickens is not that high even after 48 hours, it can be assumed that the cause of the dead chickens is an attenuated infectious disease such as attenuated avian influenza. Furthermore, if a chicken dies only once, the cause of the death can be assumed to be, for example, stress-induced pecking behavior. In addition, if multiple dead chickens occur in one rearing area (cage), it can be assumed that the cause of the dead chickens may be a water outage due to a clogged drinking fountain in the cage in question.

[0011] The occurrence cause estimation unit may estimate the cause of the occurrence of abnormal chickens based on information on the time-dependent changes in areas where abnormal chickens have occurred and / or the time-dependent changes in the number of abnormal chickens, as well as information on environmental factors including wind direction and / or temperature within the chicken coop, or information on the relative positions of multiple areas where abnormal chickens have occurred within one chicken coop. With this configuration, environmental factors including wind direction and / or temperature within the poultry house, as well as the relative positions of multiple areas where abnormal chickens have occurred, are taken into consideration, making it possible to estimate the cause of the occurrence of abnormal chickens with even greater accuracy.

[0012] The occurrence cause estimation unit may estimate the cause of the occurrence of abnormal chickens using a machine learning model. Here, the machine learning model is obtained by machine learning training data on the past changes over time in areas where abnormal chickens have occurred and / or the changes over time in abnormal chickens, and the causes of the occurrence of abnormal chickens. With this configuration, the cause of the occurrence of abnormal chickens can be estimated with even greater accuracy.

[0013] As mentioned above, workers patrol the poultry house every day. During this patrol, the number of dead chickens and the locations of the dead chickens are recorded in a paper ledger for management purposes. If workers carry portable terminals that can transfer information about abnormal chickens to the abnormal chicken information management system during patrol work and can easily input it at the site of discovery, it will be possible to collect abnormal chicken information without placing a burden on the workers. For this reason, the abnormal chicken information management system of the present invention can be operated by an operator in the poultry house, and further includes a mobile terminal for inputting the abnormal chicken information, and the abnormal chicken information recording unit may record the abnormal chicken information input by the mobile terminal in chronological order. With this configuration, abnormal chicken information can be easily entered when patrolling the chicken coop, reducing the burden on workers. Furthermore, since patrolling the chicken coop is done at least once a day, and sometimes two or three times a day depending on the chicken farm, by entering abnormal chicken information on the mobile device at these times, the abnormal chicken information can be updated at least once a day.

[0014] The abnormal chicken information management system of the present invention further includes an imaging camera that is moved manually or automatically within the chicken coop along the specified rearing area, and an abnormal chicken information generation unit that counts the number of abnormal chickens from images captured by the imaging camera and generates the abnormal chicken information, and the abnormal chicken information recording unit may record the abnormal chicken information generated by the abnormal chicken information generation unit in chronological order. With this configuration, abnormal chicken information, including the number of abnormal chickens, can be recorded by time simply by capturing images of a specified rearing area with an imaging camera. As a result, it is possible to eliminate the need for workers to input information into their mobile devices. In addition to the worker inputting abnormal chicken information into their mobile devices, the imaging camera can also capture images. Position information can be obtained by equipping a mobile device or a mobile camera with a GNSS receiver (e.g., a GPS receiver). The minimum unit of position information (the positioning accuracy of the GNSS receiver) does not need to be a single rearing area, but can also be a position within the poultry house, including errors. Furthermore, height (three-dimensional) information can be obtained by capturing planar positions with a GNSS receiver and inputting height information into a mobile device.

[0015] The abnormal chicken information recording unit may be configured to classify and record abnormal chickens into a plurality of classification categories including at least dead chickens. With this configuration, abnormal chickens are classified into a plurality of categories that include at least dead chickens, so the cause of the occurrence can be estimated with greater accuracy.

[0016] In addition, the abnormal chicken information management system of the present invention is an abnormal chicken information management system for a chicken coop that houses laying hens in each of specified rearing areas, and is operable by an operator within the chicken coop, and is characterized by comprising: a mobile terminal for inputting abnormal chicken information including at least two-dimensional or three-dimensional location information and the number of abnormal chickens in the chicken coop in the area where abnormal chickens occur; and an abnormal chicken information recording unit that records the abnormal chicken information input by the mobile terminal in chronological order. With this configuration, abnormal chicken information can be easily entered when patrolling the poultry house, reducing the burden on workers. Furthermore, since patrols of the poultry house are carried out at least once a day, and in some poultry farms two to three times a day, by entering abnormal chicken information via a mobile device at these times, the abnormal chicken information can be updated at least once a day. Because the abnormal chicken information is recorded by time, the cause of the occurrence of abnormal chickens can be estimated based on the time-dependent changes in the areas where abnormal chickens have occurred and / or the time-dependent changes in the number of abnormal chickens. [Effects of the Invention]

[0017] According to the present invention configured in this way, it is possible to provide an abnormal chicken information management system that estimates the cause of the occurrence of abnormal chickens. [Brief explanation of the drawings]

[0019] Hereinafter, embodiments of the abnormal chicken information management system according to the present invention will be described with reference to the drawings. Note that in all of the drawings shown below, parts are omitted or exaggerated as appropriate for ease of understanding. Identical components are designated by the same reference numerals, and their description will be omitted as appropriate.

[0020] <Configuration of abnormal chicken information management system> As shown in Figure 1, the abnormal chicken information management system 100 of this embodiment manages abnormal chickens in a chicken coop 10 that houses one or more egg-laying hens in each of specified rearing areas (cage 11 in this case).

[0021] Here, the chicken coop 10 is an egg-laying chicken coop with an artificial environment adjustment function, such as a closed chicken coop (windowless chicken coop). In this chicken coop 10, multiple cage rows 12, each consisting of multiple cages 11 connected in one direction, are arranged in a line in the vertical and horizontal directions. In this embodiment, two cage rows 12 are adjacent to each other in the horizontal direction, and are arranged in multiple rows (four rows in this case) in the vertical direction.

[0022] Specifically, as shown in FIG. 1, the abnormal chicken information management system 100 manages abnormal chicken information including two-dimensional or three-dimensional location information and the number of abnormal chickens in at least the area where abnormal chickens occur (hereinafter, abnormal cages 11x) in the chicken coop 10, and is equipped with a mobile terminal 2 for inputting the abnormal chicken information and a management server 3 for managing the abnormal chicken information.

[0023] The mobile terminal 2 is a device that can be carried and operated by an operator inside the poultry house 10, and is, for example, a smartphone or tablet. Two-dimensional or three-dimensional position information of the abnormal cage 11x in the poultry house 10 and abnormal chicken information including the number of abnormal chickens are input into this mobile terminal 2. An example of how to represent the three-dimensional position information of the abnormal cage 11x is shown in Figure 2. In Figure 2, a group of cage rows 12 consisting of a total of eight cage rows, two rows left and right and four rows up and down, is referred to as a "mountain." The cage numbers of each cage row are assigned sequentially from one end to the other, as 1, 2, 3, ...

[0024] In the mobile terminal 2 of this embodiment, not only two-dimensional or three-dimensional position information of the abnormal cage 11x (for example, mountain number, left / right information, and cage number) and the number of abnormal chickens, but also the type of abnormal chicken (for example, dead chickens, chickens that died in accidents (guillotine chickens), weak chickens, other abnormal chickens, etc.) are input as abnormal chicken information. Specifically, the number of abnormal chickens for each type is input into the mobile terminal 2. Furthermore, the mobile terminal 2 can also input details of how to deal with abnormal chickens (for example, removal or observation, etc.) as abnormal chicken information. Specific input screens on the mobile terminal 2 will be described later.

[0025] The management server 3 manages the abnormal chicken information input by the mobile terminal 2 and estimates the cause of the occurrence of abnormal chickens from the abnormal chicken information. The management server 3 is communicably connected to the mobile terminal 2 via a network.

[0026] The management server 3 can be configured by a computer having a CPU, memory, an input / output interface, an AD converter, input devices such as a keyboard and a mouse, a display device such as a display, a communication device, etc. The management server 3 may be configured by a single computer or by multiple computers. Furthermore, the management server 3 may be a cloud server.

[0027] Specifically, the management server 3 has an abnormal chicken information recording unit 31 and an occurrence cause estimation unit 32, as shown in FIG.

[0028] The abnormal chicken information recording unit 31 records the abnormal chicken information input by the mobile terminal 2 in chronological order (by time). Here, recording the abnormal information in chronological order means, for example, recording by the time when patrol work was carried out at the poultry house 10 (patrol work time). In other words, the abnormal chicken information recording unit 31 records the abnormal chicken information for each patrol work.

[0029] For example, if patrol work is performed once a day, the abnormal chicken information recording unit 31 records the abnormal chicken information for each day. If patrol work is performed twice a day, the abnormal chicken information recording unit 31 records the abnormal chicken information every half day (every 12 hours), and if patrol work is performed once every two days, the abnormal chicken information recording unit 31 records the abnormal chicken information every two days.

[0030] The abnormal chicken information recording unit 31 can also classify and record abnormal chickens into a plurality of classification categories. Here, the plurality of classification categories are the types of abnormal chickens (for example, dead chickens, chickens that died by accident (guillotine chickens), weak chickens, other abnormal chickens, etc.) input from the mobile terminal 2. In addition, the abnormal chicken information recording unit 31 can record various types of information input to the mobile terminal 2 by patrol work time.

[0031] The occurrence cause estimation unit 32 estimates the cause of the occurrence of abnormal chickens based on information on the change over time in the number of abnormal cages and / or the change over time in the number of abnormal chickens obtained from the abnormal chicken information recorded in the abnormal chicken information recording unit 31. Specifically, the occurrence cause estimation unit 32 estimates the cause of the occurrence of abnormal chickens based on four-dimensional information on the change over time in the number of abnormal cages and / or the change over time in the number of abnormal chickens during multiple patrol operations.

[0032] Furthermore, the occurrence cause estimation unit 32 estimates the cause of the occurrence of abnormal chickens based on information on the change over time in the number of abnormal cages and / or the change over time in the number of abnormal chickens, as well as information on environmental factors including wind direction and / or temperature within the poultry house 10, or information on the relative positions of multiple abnormal cages 11x within one poultry house 10. Note that information on environmental factors including wind direction, temperature, etc. within the poultry house 10 can be input into the mobile terminal 2, or can be sent to the management server 3 from a control system (not shown) for the poultry house 10.

[0033] Furthermore, the occurrence cause estimation unit 32 can also estimate the cause of the occurrence of abnormal chickens using a machine learning model. Here, the machine learning model is obtained by machine learning training data on information on past changes in abnormal cages over time and / or changes in abnormal chickens over time, and the causes of the occurrence of abnormal chickens.

[0034] <Example of Estimation of Cause of Occurrence by Cause Estimation Unit 32> An example of how the cause of occurrence of abnormal chickens is estimated by the cause estimation unit 32 will be described below.

[0035] The cause of occurrence estimation unit 32 can estimate the cause of abnormal chickens, such as dead chickens, that occur in the poultry house 10 based on the time that has passed since the occurrence and the extent to which the number of dead chickens has increased.

[0036] <Estimation example 1> One dead chicken occurred in cage 26 on the right side of the fourth floor (see Figure 3). The next day (see Figure 4), a total of eight chickens died in four surrounding cages. In this case, the dead chickens spread rapidly 24 hours after the initial outbreak (cage no. 26 on the R side of the 4th floor), and they spread in the direction of ventilation in the chicken coop 10. Therefore, it can be assumed that the cause of the dead chickens is a highly virulent infectious disease, such as highly virulent avian influenza.

[0037] <Estimation example 2> One dead chicken occurred in cage 26 on the right side of the fourth floor (see Figure 3). The next day, one chicken died in cage 27 downwind. The day after that, three chickens died nearby. In this case, although the dead chickens spread in the direction of ventilation in the chicken coop, the number of dead chickens was not that large even after 48 hours, so it can be assumed that the cause of the dead chickens was a weakly virulent infectious disease such as weakly virulent avian influenza.

[0038] <Estimation example 3> One dead chicken occurred in cage 26 on the right side of the fourth floor (see Figure 3). The next day, no changes in the nearby cages The day after that, there was no change in the nearby cage. In this case, since the dead chickens are isolated, it can be assumed that the cause of the dead chickens is, for example, stress-induced pecking of the bottoms. In this case, it may be possible to instruct workers to observe the bottoms of the dead chickens.

[0039] If multiple chickens die in one rearing area (cage), it can be assumed that the cause of the deaths is, for example, a water outage caused by a clogged drinking fountain in the cage in question. If a water outage occurs, the chickens in the cage in question will die within about three days (usually about six to eight chickens per cage). If a problem with the feeder continues and they are unable to feed, the egg-laying rate will decrease, but unless the chickens are extremely weak, they will not die within three days.

[0040] <Method of inputting abnormal chicken information using mobile terminal 2> Next, we will explain how to input abnormal chicken information using the mobile terminal 2. In this embodiment, the mobile terminal 2 is configured so that information can be input simply by touching the display.

[0041] By touching the icon displayed on the display of the mobile terminal 2, the abnormal chicken management application (software) installed on the mobile terminal 2 is started.

[0042] When the abnormal chicken management app is launched, the worker who will be performing patrol work is registered. Here, the worker is registered by entering the worker's ID. Specifically, the worker is registered by reading an identifier (for example, a two-dimensional code such as a QR code) assigned to each worker with the camera of the mobile terminal 2. Note that the worker's ID may also be entered manually by the worker.

[0043] Once the worker registration is complete, the display of the mobile terminal 2 displays the worker reading completion screen W1, as shown in FIG. 5(a). This worker reading completion screen W1 displays a "Start patrol" button, and when this "Start patrol" button is touched, the abnormal chicken management app switches to poultry house patrol mode. Then, the display of the mobile terminal 2 displays the default screen W2, as shown in FIG. 5(b). The patrol route for the poultry house 10 may be predetermined or may be freely determined by the worker.

[0044] In the poultry house patrol mode, a camera is activated to read a cage area identifier 20 (for example, a two-dimensional barcode such as a QR code; see Figures 1 and 6(a)), which will be described later. The default screen W2 displays a "QR scan inside poultry house" screen for reading the cage area identifier 20. The default screen W2 also displays a "Done" button for ending the poultry house patrol mode. Even if the mobile terminal 2 goes to sleep during the poultry house patrol, the default screen W2 will be displayed by activating the mobile terminal 2.

[0045] If a worker finds an abnormal chicken while patrolling the poultry house, the worker captures an image of the cage area identifier 20 attached to the cage area containing the abnormal cage with the camera of the mobile terminal 2 and reads it. In this embodiment, the cage area is an area that contains, for example, a total of eight cages, two at the front and two at the back, and four at the top and four at the bottom, but the number of cages included is not limited to this. When this cage area identifier 20 is read, a cage selection screen W3 is displayed, as shown in FIG. 6(b). This cage selection screen W3 displays multiple cage selection buttons corresponding to the arrangement of the multiple cages in the cage area (see FIG. 6(a)).

[0046] Then, the worker touches the selection button corresponding to the abnormal cage (here, "fourth floor-22") from among the selection buttons for multiple cages displayed on the cage selection screen W3.

[0047] After selecting an abnormal cage, an abnormality selection screen W4 is displayed as shown in Figure 7(a). This abnormality selection screen W4 is a screen for inputting the type and number of abnormal chickens. In this embodiment, the abnormality selection screen W4 displays a "Dead Chicken" button, a "Limp (Weak Chicken)" button, an "Other" button, an "Input Number" button, and an "OK" button.

[0048] On this abnormality selection screen W4, first select the type of abnormal chicken. Then, enter the number of chickens with the same symptom in the same cage (see Figure 7(b)). Once you have finished entering the same symptom in the same cage, touch the "OK" button. By touching the "OK" button, the entered data is automatically saved in the memory of the mobile terminal 2 along with the time data. Also, by touching the "OK" button, the mobile terminal 2 displays the default screen W2 (see Figure 5(b)).

[0049] If there are abnormal chickens of a different type in the abnormal cage, read the cage area identifier 20 again, select the abnormal cage (here, "4th floor-22"), select another type, enter the number of chickens, and then touch the "OK" button.

[0050] Furthermore, if an abnormal chicken is found in another cage included in the cage area, read the cage area identifier 20 again, select the abnormal cage (for example, "2nd floor-21"), select the type of abnormal chicken, enter the number of chickens, and then touch the "OK" button.

[0051] The worker repeats the above steps while patrolling the chicken coop 10, and when the patrol is complete, the worker touches the "Complete" button on the default screen W2, and then touches the "OK" button displayed on the patrol completion screen W5, as shown in Figure 8(a).

[0052] When the "OK" button on the patrol completion screen W5 is touched, an abnormal chicken information screen W6 will be displayed on the display of the mobile terminal 2, as shown in Figure 8(b). This abnormal chicken information screen W6 displays a list of the abnormal chicken information (cage number, abnormal type, number of chickens) entered during the current patrol. In addition, the abnormal chicken information screen W6 displays a "Transfer" button for sending the abnormal chicken information to the management server 3.

[0053] When the "Transfer" button on the abnormal chicken information screen W6 is touched, the abnormal chicken information stored in the memory of the mobile terminal 2 is transferred together with the time data of each abnormal chicken to the management server 3. If the management server 3 is installed in the office (not shown) of the poultry house 10, this data transfer can be performed by short-range wireless communication such as Wi-Fi after the user returns to the office.

[0054] <Effects of this embodiment> According to the abnormal chicken information management system 100 of this embodiment, the cause of the occurrence of abnormal chickens can be accurately estimated by focusing on the changes over time in the number of abnormal cages 11x and / or the changes over time in the number of abnormal chickens.

[0055] Furthermore, abnormal chicken information can be easily input using portable terminal 2 when patrolling chicken coop 10, reducing the burden on workers. Furthermore, since patrolling chicken coops is done at least once a day, and two to three times a day depending on the chicken farm, inputting abnormal chicken information using portable terminal 2 at these times means that the abnormal chicken information is updated at least once a day.

[0056] <Modified embodiment of the present invention> The present invention is not limited to the above-described embodiment.

[0057] For example, input of abnormal chicken information into the mobile terminal 2 is not limited to touch operation, and the abnormal chicken information may be input using the keyboard of the mobile terminal 2.

[0058] Furthermore, the abnormal chicken information recorded in the management server 3 may be output daily, weekly, or monthly (e.g., CSV output), and the abnormal chicken information may also be output for each cage row (e.g., CSV output).

[0059] Furthermore, the management server 3 may identifiably display information on the change over time in the number of abnormal cages 11x and / or the change over time in the number of abnormal chickens on a three-dimensional model of the poultry house 10 or multiple cage rows 12, based on the abnormal chicken information recorded in the abnormal chicken information recording unit 31. For example, as shown in Figures 3 and 4, the cages containing abnormal chickens and their numbers may be displayed in a switched manner on a daily basis, or these may be superimposed and displayed in an identifiable manner on a daily basis.

[0060] In the above embodiment, a cage area identifier 20 is provided for each cage area including a plurality of cages 11, but a configuration may also be adopted in which a cage identifier is provided for each cage and the cage position information is input by reading the cage identifier with the mobile terminal 2. Also, a configuration may also be adopted in which the worker inputs the cage number without reading the identifier.

[0061] Furthermore, as shown in FIG. 9, the abnormal chicken information management system 100 may further include an imaging camera 4 that is manually or automatically moved along multiple cage rows 12 within the chicken coop 10, and an abnormal chicken information generation unit 5 that generates abnormal chicken information including position information of abnormal cages 11x and the number of abnormal chickens from images captured by the imaging camera 4.

[0062] The imaging camera 4 may be one that captures still images or one that captures moving images. When the imaging camera 4 is moved manually, it is possible to use a camera provided in the mobile terminal 2. When the imaging camera 4 is moved automatically, it is possible to provide the imaging camera 4 in a feeder or a running device that moves along the row of cages.

[0063] The abnormal chicken information generation unit 5 can be provided in the mobile terminal 2 or the management server 3. If the abnormal chicken information generation unit 5 is provided in the management server 3, a large amount of image data will be transmitted from the mobile terminal 2 to the management server 3. For this reason, it is desirable to provide the abnormal chicken information generation unit 5 in the mobile terminal 2.

[0064] The abnormal chicken information generation unit 5 uses image data captured by the imaging camera 4 to identify the presence or absence of abnormal chickens and their types. The abnormal chicken information generation unit 5 then identifies abnormal cages 11x from the image data and specifies the number of abnormal chickens. The location information can be obtained by equipping the mobile terminal 2 or the mobile imaging camera 4 with a GNSS receiver (e.g., a GPS receiver). The minimum unit of location information (the positioning accuracy of the GNSS receiver) does not need to be a single rearing area, but can also be a position within the poultry house 10 that includes an error. Furthermore, the planar position can be obtained by the GNSS receiver, and height information can be input into the mobile terminal to obtain height (three-dimensional) information.

[0065] Furthermore, although the abnormal chicken information management system 100 in the above embodiment is configured to include the occurrence cause estimation unit 32, it may be configured not to include the occurrence cause estimation unit 32. Even in this case, the cause of the occurrence can be estimated by transmitting the abnormal chicken information recorded in the abnormal chicken information recording unit 31 to an analysis device separate from the abnormal chicken information management system 100. The cause of the occurrence can also be estimated by manually analyzing the abnormal chicken information recorded in the abnormal chicken information recording unit 31.

[0066] Furthermore, the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
