Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

The embodiment of the present disclosure described below will be described mainly using pigs as livestock. In livestock farming, the number of pigs raised on one farm may be in the thousands to tens of thousands, which imposes a heavy management burden on a huge number of livestock.

Pigs are mainly divided into breeding pigs and non-breeding pigs. Breeding pigs are pigs raised to produce piglets, and non-breeding pigs are pigs (meat pigs) raised for shipping after growth. Since the number of non-breeding pigs is larger than that of breeding pigs, it is difficult to manage each individual pig, and therefore it is common to manage a plurality of pigs as a group. The pigs described below are primarily intended for non-breeding pigs. In the following description, the term "day age" refers to the number of days elapsed with the weaning date as the reference date. As the age, the number of days elapsed based on the date of birth may be used.

The selling price of pigs distributed in Japan is the wholesale price in units of ratings and grades determined by the weight, meat quality, etc. of the individual pigs supplied, in addition to the relationship between supply and demand at each central wholesale market and local meat market. (Unit price per kg) is determined. The grade is determined by whether or not the carcass half-round weight of the slaughtered carcass is within the specified range. The grades are classified into four stages of "excellent", "high", "medium", and "normal", and "non-standard" that does not correspond to the grade is further classified. Therefore, in order to increase profits, it is desirable to raise pigs so that their weight falls within the range of this grade (appropriate weight range). Furthermore, it can be expected that profitability will be further enhanced by setting the higher grades of "upper" and "excellent" to the appropriate weight range.

Pigs are generally bred in multiple compartments of pigs in a piggery, which is a building on the farm. A pig bunch is an environment where pigs are bred in units of dozens of pigs. In addition, dozens of pigs placed in pig bunches are treated as a management group.

Non-breeding pigs are managed by giving a group identifier for group management to multiple pigs. The group identifier is managed by assigning a group identifier (group ID) in which a plurality of pigs are grouped together. The group identifier is managed by associating a piggery ID indicating a piggery with a piglet ID indicating a piggery in the piggery.

FIG. 1 is a system configuration diagram showing a livestock information management system 1 including a livestock information management server 101 according to the first embodiment of the present disclosure. As shown in FIG. 1, the livestock information management system 1 according to the embodiment of the present disclosure includes a livestock information management server 101, a terminal device 201 used by a livestock industry (user), and a weight scale and temperature provided in the piggery 301. Measuring instruments such as sensors and humidity sensors, terminal devices, and the like are communicably connected via a network NW such as the Internet, LAN, and VPN (Virtual Private Network). For the sake of simplification of the description, although only the terminal device 201 is shown assuming one user in FIG. 1, the livestock information management server 101 can be connected to the terminal devices of a plurality of users via the network NW. Further, although the piggery 301 is shown assuming one piggery, the livestock information management server 101 can be connected to a plurality of piggery 301s via the network NW.

The livestock information management system 1 is a system that mainly supports the management of livestock information performed by the livestock industry (user). The operator of the livestock information management system uses the system to provide the livestock industry with a service that supports the management of livestock information. The operator can provide services to multiple livestock farmers. The livestock information management server 101 is managed by the operator of the livestock information management system 1, and the livestock industry uses the terminal device 201. The livestock information management server 101 may be managed by the livestock industry itself.

The livestock information management server 101 includes an estimation unit 111, a weight information acquisition unit 112, a production information acquisition unit 113, a management information acquisition unit 114, a turnover processing unit 115, a livestock information storage unit 121, and a mathematical model storage unit 122. The livestock information management server 101 is, for example, a server device (server computer) or the like.

The estimation unit 111 includes weight information associated with the individual weights of the plurality of pigs belonging to the management group stored in the livestock information storage unit 121, which will be described later, and the dates on which the weights were measured, and the plurality of pigs belonging to the management group. Estimate the weight distribution of a plurality of pigs at an arbitrary timing (estimated desired timing) at a predetermined timing (estimated calculation timing) using the attribute information of the management group including the information on the weaning date of the pig and the mathematical model described later. Has a function. The estimation calculation timing can be, for example, a timing based on the timing at which the latest individual weights of a plurality of pigs are measured at the time of estimation, or the timing at which the latest individual weights are measured. The estimated desired timing is the timing at which the estimation unit 111 estimates the body weight distribution at an arbitrary time point, and the estimation unit 111 can generate it. For example, with the weaning date as a reference, a plurality of days after the date on which the body weight is measured can be generated as the estimated desired timing. Further, a predetermined timing may be used as the estimated desired timing.

Further, the estimation unit 111 estimates the timing at which the estimated weight distribution satisfies the preset weight distribution. For example, the timing at which the estimated weight distribution satisfies a predetermined shipping condition can be estimated as the scheduled shipping date. The shipping conditions are, for example, a condition in which the weight of the entire group is maximized and a condition in which the weight distribution falls within an appropriate weight range, and conditions in which the weight distribution for shipping is optimized.

Further, the estimation unit 111 can calculate basic statistics such as average weight, maximum frequency, maximum value, minimum value, standard deviation, kurtosis, and skewness based on the estimated weight distribution. The body weight distribution estimated by the estimation unit 111 is a body weight distribution after the time when the weight information of each livestock acquired by the weight information acquisition unit 112 is measured, but it goes back from the time when the weight information of the livestock is measured. You may estimate the weight distribution.

The body weight information acquisition unit 112 has a function of associating the weight of each livestock belonging to the management group with the timing (day) when the weight of the livestock belonging to the management group is measured and acquiring it as body weight information.

You may enter from the weight information stored in the system. The body weight information acquisition unit 112 stores the acquired body weight information in the livestock information storage unit 121 in association with the attribute information of the management group described later. Further, the body weight information acquisition unit 112 presents to the user the timing at which the user measures the weight of the pig belonging to the management group in order to acquire the body weight in the period in which the body weight distribution is estimated as the actual body weight after estimating the body weight distribution. It is possible to generate measurement timing information for the purpose. The body weight information acquisition unit 112 can calculate the measurement timing information based on the day when the last weight measurement of the pigs belonging to the management group was performed. The body weight information does not necessarily have to be associated with the individual body weights of the livestock belonging to the management group and the timing at which the individual body weights are measured. For example, the individual body weights of the livestock belonging to the management group and the set of individual body weights. The data may be associated with the timing of measurement as a management group.

The production information acquisition unit 113 has a function of acquiring history information indicating the breeding history of pigs belonging to the management group. The breeding history information is information indicating the history of the breeding process of pigs to which the management group belongs, and is information including, for example, feeding history, medication history, movement history of piggery and pig bunches, and the like. The acquired breeding history information is associated with the management group and stored in the livestock information storage unit 121 as attribute information. The breeding history information can be obtained from the information aggregated by other information management systems (not shown). The breeding history information may be aggregated in the livestock information management server 101 according to the present embodiment.

The management information acquisition unit 114 has a function of acquiring management information regarding the breeding environment of pigs belonging to the management group. The management information is information showing the history of the environment of the pig bunches in the piggery 301, which is the breeding place for pigs to which the management group belongs. Specifically, the information including the temperature and humidity and the time when the temperature and humidity information associated therewith is acquired is the information associated with the piggery ID and the pig bunch ID, but is not limited thereto. In addition, the management information includes information on whether or not the pig bunches are washed, disinfected, and dried, and the time required for their implementation (lead time). The management information acquisition unit 114 can acquire information from the temperature sensor and the humidity sensor provided in the piggery 301 via the network NW. The management information may be input by the user from the input unit 211 of the terminal device 201. The acquired management information is associated with the management group and stored in the livestock information storage unit 121 as attribute information. The management information may be aggregated as history information by another information management system (not shown), or may be acquired from the information management system.

The turnover processing unit 115 calculates the breeding lead time from the weaning date to the scheduled shipping date based on the estimated shipping date calculated by the estimation unit 111 for each management group, and each pig bunch acquired from the management information acquisition unit 114. It has a function to calculate pig bunch turnover information together with the management information (lead time required for cleaning, disinfection, and drying). The turnover rate (pig bunch turnover rate) indicates the number of times pigs have been raised and shipped within a predetermined period, and can be shown as, for example, the number of times per year.

The livestock information storage unit 121 stores attribute information indicating the attributes of the management group, which is a group that manages pigs, individual weights of a plurality of pigs belonging to the management group, and weight information associated with the date on which the weights were measured. Has the function of The attribute information of the management group includes the group ID of the management group, the number of pigs belonging to the management group, the weaning date of the pigs belonging to the management group, the pig house ID indicating the piggery and the pig bunches that are the breeding places of the pigs belonging to the management group, and the pigs. Information including the tuft ID. When dealing with a plurality of pig breeds, the breed information (type information) may be included in the attribute information. Further, the history information acquired by the production information acquisition unit 113 is stored as attribute information associated with the management group. Further, the management information acquired by the management information acquisition unit 114 is stored as attribute information associated with the management group. If the weaning days of pigs actually vary by several days from the individual weaning days of the pigs belonging to the management group, the central day may be set as a representative value. Further, the date of birth may be memorized instead of the date of weaning of the pig, or both the date of weaning and the date of birth may be memorized. In addition, the livestock information storage unit 121 stores conditions (shipping conditions) for the estimation unit 111 to estimate the timing at which the estimated weight distribution satisfies a preset condition. The condition can be arbitrarily set by the user.

The mathematical model storage unit 122 has a function of storing a mathematical model for estimating the weight distribution on a specified day by using the acquired pig weight information. The mathematical model storage unit 122 stores a plurality of mathematical models, and the stored mathematical models can be updated. For the mathematical model, for example, by constructing a plurality of mathematical models by utilizing the history information of the body weight acquired in the past, the breed, the waiter, the illness, the piggery environment information, etc., the mathematical model according to the state of the attribute information is selected. Can be done. Further, as the mathematical model, an appropriate mathematical model can be selected according to the date (age) from the weaning date. For example, the weight gain phase and the meat quality improvement phase in FIGS. 3 and 4, which will be described later, change from the weaning day to the dc day. The weight gain phase gains weight, and the meat quality improvement phase suppresses excessive weight gain and converges the weight variability of individual pigs, and the accuracy of weight estimation can be improved by using different mathematical models. Because. In addition, by selecting a mathematical model that responds to the breed information included in the attribute information of the management group to be estimated, for example, even when varieties with different degrees of weight gain with respect to the amount of feed are mixed, the weight distribution is estimated. The accuracy can be improved.

As a mathematical model, for example, a Bayesian inference model can be used. By using the Bayesian estimation model, the estimation unit 111 mathematically uses the acquired measured body weight (past actual body weight) and the newly acquired body weight (current actual body weight) of the pigs belonging to the management group to be estimated. Models can be updated, for example parameters. Therefore, it is possible to improve the accuracy of estimating the future weight information of pigs belonging to the management group for which the estimation is performed. The mathematical model is not limited to the Bayesian estimation model, and other models such as a neural network and an AutoRegressive (AR) model may be used.

The terminal device 201 is, for example, a device such as a PC, a smartphone, a tablet PC, and a mobile phone. The terminal device 201 may access the livestock information management server 101 by the dedicated application software installed on the terminal. Further, the livestock information management server 101 may be accessed by using the operating environment (API (application programming interface), platform, etc.) provided by the livestock information management server 101.

The input unit 211 has a function that allows information to be input and selected by being operated by a user such as a keyboard, a mouse, or a touch pad. Further, a touch panel integrated with a display unit 212 such as a liquid crystal display or an organic EL display in a smartphone, a tablet, or a PC may be used. The input unit 211 may be a voice input device.

The display unit 212 is a display device or the like having a function of displaying information or the like to the user. It may be a display device independent of the terminal device 201, or it may be a display device such as a liquid crystal display or an organic EL display in a smartphone or tablet. The display unit 212 can display the weight distribution estimated by the estimation unit 111.

Note that the terminal device 201 may be configured integrally with the livestock information management server 101 without going through the network NW.

<Processing flow>
Next, the operation of the livestock information management system 1 according to the embodiment of the present disclosure will be described with reference to the flowchart shown in FIG.

In step S101, the body weight information acquisition unit 112 acquires the body weight of each livestock and the day on which the body weight is measured in association with each other as body weight information. The body weight information acquisition unit 112 stores the acquired body weight information in the livestock information storage unit 121 in association with the attribute information of the management group.

In step S102, the estimation unit 111 acquires the attribute information of the management group from the livestock information storage unit 121.

In step S103, the estimation unit 111 measures the latest individual weights of the plurality of pigs at the time of estimation by using the attribute information of the management group acquired in step S102 and the weight information acquired in step S101. Estimate the body weight distribution at one or more subsequent timings (estimated desired timing) at the same timing (estimated calculation timing). The estimation unit 111 can select a mathematical model used for estimating the body weight distribution from the mathematical model storage unit 122 in which a plurality of mathematical models are stored according to the attribute information of the management group for which the estimation is performed. In addition, the mathematical model may be changed according to the elapsed time from the weaning date associated with the management group to the estimated desired timing. The estimated body weight distribution is associated with the attribute information of the management group and stored in the livestock information storage unit 121. The information of the estimation model used may be recorded in the mathematical model storage unit.

In step S104, the estimation unit 111 estimates the day when the weight distribution satisfies the shipping condition from the weight distribution estimated in step S103. That is, the estimated shipping date can be estimated. Here, the shipping condition is a condition in which the weight distribution falls within the appropriate weight range and the weight of the entire group is maximized. The condition can be arbitrarily set by the user.

In step S105, the display unit 212 displays the weight distribution estimated in step S103. In addition, the estimated shipping date in step S104 can be displayed.

In step S106, the body weight information acquisition unit 112 acquires the body weight of each livestock belonging to the management group measured after the estimation calculation timing of step S103 and the body weight information associated with the date on which the body weight was measured as the actual body weight. To do. The body weight information acquisition unit 112 stores the acquired actual body weight in the livestock information storage unit 121 in association with the attribute information of the management group.

In step S107, the estimation unit 111 updates the mathematical model using the weight distribution estimated at the estimation calculation timing prior to step S103 and the actual weight acquired in step S106. Then, using the actual body weight acquired in step S106, the body weight distribution is estimated (repredicted) at the later estimation calculation timing. The estimated (repredicted) weight distribution is associated with the attribute information of the management group and stored in the livestock information storage unit 121. The information of the estimation model used may be recorded in the mathematical model storage unit.

In step S108, the estimation unit 111 estimates and updates the day when the weight distribution meets the shipping conditions from the weight distribution estimated in step S107.

In step S109, the display unit 212 displays the weight distribution estimated in step S107 and the previously estimated weight distribution. In addition, the estimated shipping date in step S108 can be displayed.

<About changes in pig weight>
Next, the change in the weight of the pig will be described. FIG. 3 is a graph showing changes in the body weight of pigs handled by the livestock information management system according to the embodiment of the present disclosure. The horizontal axis of FIG. 3 is the number of days (day age) starting from the date of weaning from a sow or the like (which may be a suckling device), and the vertical axis shows the body weight.

As shown in FIG. 3, pigs (non-breeding pigs) are shipped after undergoing a weight gain phase and a meat quality improvement phase. The weight gain phase is a phase in which the body weight is gained in a predetermined period after weaning. In addition, the meat quality improvement phase is a phase for suppressing excessive weight gain after the end of a predetermined period, converging the variation in body weight of individual pigs, and keeping the body weight distribution within a predetermined range. The weight gain phase is from the weaning date to the day-age dc, and the meat quality improvement phase is from the day-age dc to the day-age ds, which is the shipping date. Since non-breeding pigs are group-managed as described above, the weight of pigs belonging to the controlled group is expressed as a body weight distribution. The body weight distributions 151 m to 168 m in FIG. 3 show the daily age transition of the body weight distribution of pigs belonging to the management group in a box plot. In addition, an image diagram of a frequency distribution showing the number of pigs for each body weight is also shown in the body weight distributions 151 m, 161 m, and 168 m.

As shown in FIG. 3, the livestock farmer gains weight of the pig so as to approach the shipping target weight w1 of the pig during the weight gain phase, and sets the weight distribution to the shipping target weight w1 during the meat quality improvement phase. Keep them close to each other. As shown in the area 180, if the weight of each pork falls within the range defined as "excellent" centering on the shipping target weight w1, it is regarded as "excellent", and the grade is "upper" according to the expansion of the weight range. It becomes "medium" and "medium". The range that does not correspond to this grade is "non-standard". The grade of meat quality is not determined only by body weight, but it is a prerequisite that the body weight is at least within the specified range. That is, it is necessary to carry out the breeding in the weight gain phase and the meat quality improvement phase so that the weight of the pig falls within the range of this grade (appropriate weight range).

FIG. 4 is a graph showing changes in the body weight of pigs during breeding and changes in estimated predicted values of the changes in body weight. FIG. 4A is a graph in which the predicted value is estimated when the estimated calculation timing is p1 day, and FIG. 4B is a graph of the predicted value re-estimated when the estimated calculation timing is p2 day after p1 day. It is a graph. Similar to FIG. 3, in both FIGS. 4 (a) and 4 (b), the horizontal axis is the number of days starting from the weaning date from a sow or the like (which may be a suckling device), and the vertical axis is the number of days. Shows weight.

In FIG. 4 (a), the body weight distributions 151 m to 158 m show the actually measured body weight distributions of pigs belonging to the management group in a box plot. The weight distributions 159p to 168p show the weight distributions of the predicted values of the plurality of estimated desired timings estimated on p1 day in a box plot. In addition, an image diagram of a frequency distribution showing the number of pigs for each body weight based on actual measured values is also shown in the body weight distribution 151 m. In the body weight distribution 161p and 168p, an image diagram of the frequency distribution showing the number of pigs for each body weight based on the estimated value is also shown.

In FIG. 4 (b), the body weight distributions 151 m to 161 m show the actually measured body weight distributions of pigs belonging to the management group in a box plot. The weight distributions 159p to 168p show the weight distributions of the predicted values of the plurality of estimated desired timings estimated on p1 day in a box plot. Further, the body weight distributions 162p'to 168p'show the body weight distributions of the predicted values of the plurality of estimated desired timings estimated on the p2 day. The weight distributions 162p'to 168p'show the same timing of the body weight distributions as the weight distributions 162p to 168p, but the weight distributions 162p'to 168p' are slightly shifted to the right to improve the visibility of the figure. ing. In addition, an image diagram of a frequency distribution showing the number of pigs for each body weight based on actual measured values is also shown in the body weight distribution 151 m. In the body weight distributions 161m and 161p, an image diagram of a frequency distribution showing the number of pigs for each body weight based on the measured values and the estimated values corresponding to each is also shown. Further, in the body weight distributions 168p and 168p', there are a frequency distribution indicating the number of pigs per body weight according to the estimated value on p1 day and a frequency distribution indicating the number of pigs per body weight based on the estimated value on p2 day. An image diagram is also shown.

As shown in FIG. 4B, when the body weight distributions 161m and 161p are compared, the measured value of the body weight distribution 161m is heavier as a whole than the body weight distribution 161p estimated on p1 day, and the measured value and the estimated value. It can be seen that there is a divergence in. Therefore, the body weight distributions 162p'to 168p'are the weight distributions of the predicted values re-estimated by the mathematical model updated using the body weight newly acquired on p2 day in order to eliminate this dissociation. Therefore, the accuracy of the estimated body weight distribution at the age ds, which is the scheduled shipping date, is improved.
