Description

Animal product information management system, animal product information management server, animal product information management method, and animal product information management program

Technical Field

The present disclosure relates to a livestock information management system, a livestock information management server, a livestock information management method, and a livestock information management program for performing weight management of the entire group for livestock managed as a group in animal husbandry.

Background

In animal husbandry, since the growth of the fattening period not only increases the feed cost and the like, but also does not improve the meat quality performance, and also directly leads to the management pressure, there is a need for a feed management task for optimizing the determination of the delivery time and the delivery weight of livestock.

In the work of raising management, it is common practice to measure the body weight of an individual at appropriate time and adjust the feeding pattern (type, amount, etc.) based on the measured body weight.

For example, patent document 1 describes the following technique: the weight of the individual animal is automatically estimated by a computer from individual animal image data or the like obtained by a camera device, and the animal is guided and assigned to different feeding areas based on the thus-obtained weight data.

Detailed Description

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

In the embodiments of the present disclosure described below, mainly pigs will be described as livestock. In livestock production, the number of pigs raised on a farm may be from several thousand to several tens of thousands, and the management burden of a huge number of livestock is heavy.

Pigs are mainly divided into breeding pigs and non-breeding pigs. The breeding pigs are pigs raised for the purpose of producing piglets, and the non-breeding pigs are pigs (pork pigs) raised for shipment after growth. Since the number of non-breeding pigs is larger than that of breeding pigs, it is difficult to manage each pig individually, and therefore, a large number of pigs are generally managed as a herd. The pigs described below are mainly targeted for non-breeding pigs. In the following description, the day age indicates the number of elapsed days based on the weaning day. The age in days may be the number of days elapsed based on the date of birth.

The selling price of swine distributed in japan is determined in units of a rating and a grade determined from the body weight, meat quality, and the like of an individual swine to be supplied, in addition to the relationship between the demand and supply amount in each central wholesale market/local meat market. The grade is determined by whether the carcass weight of the half of the pork slaughtered to the carcass is within a defined range. The grades are divided into four stages of 'on pole', 'up', 'middle' and 'common', and are further classified into 'out of specification' which does not accord with the grades. Therefore, in order to increase the profit, it is desirable to raise the pigs in such a manner that the weight of the pigs falls within this class range (appropriate weight band). Further, by setting higher levels of "up" and "on pole" to appropriate weight bands, it is expected that the profitability is further improved.

Pigs are usually housed in a plurality of separate pig rooms formed in a pig house, which is a building in a farm. The pig room is an environment for raising pigs in units of dozens of pigs. In addition, tens of pigs placed in a pig house were treated as a management group.

The non-breeding pigs were managed by assigning a herd identifier for herd management to multiple pigs. The group identifier is managed by assigning a group identifier (group ID) for grouping the multiple pigs into a group. The group identifier is managed by associating a pigsty ID indicating a pigsty with a pigsty ID indicating a pigsty room.

< constitution >

Fig. 1 is a system configuration diagram showing an animal information management system 1 including an animal information management server 101 according to a first embodiment of the present disclosure. As shown in fig. 1, the animal information management system 1, the animal information management server 101, the terminal device 201 used by the animal owner (user), the weighing scale, the measuring instrument such as the temperature sensor and the humidity sensor, the terminal device, and the like provided in the pig house 301 are communicably connected through a network NW such as the internet, LAN, VPN (virtual private network), and the like. For simplicity of explanation, only the terminal device 201 is shown in fig. 1 assuming one user, but the stock information management server 101 may be connected to terminal devices of a plurality of users through the network NW. Further, for the pig house 301, one pig house is assumed and shown, but the stock information management server 101 may be connected to a plurality of pig houses 301 through the network NW.

The livestock information management system 1 is a system for supporting livestock information management mainly by livestock producers (users). The livestock information management system is used by a business carrier of the livestock information management system to provide services supporting livestock information management for livestock manufacturers. The operator can provide services to a plurality of livestock property providers. The animal product information management server 101 is managed by the operator of the animal product information management system 1, and the animal product operator uses the terminal device 201. The livestock property information management server 101 may be managed by the livestock property provider 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 rate processing unit 115, a livestock information storage unit 121, and a mathematical model storage unit 122. The stock information management server 101 is, for example, a server device (server computer) or the like.

The estimating unit 111 has the following functions: the weight distribution of the multiple pigs at an arbitrary timing (estimated desired timing) is estimated at a predetermined timing (estimated calculation timing) using weight information, which is stored in the livestock information storage unit 121 and which relates the weight of each of the multiple pigs belonging to the management group to the date when the weight is measured, attribute information of the management group including information on the weaning date of the multiple pigs belonging to the management group, and a mathematical model, which will be described later. The estimation calculation timing may be, for example, timing for measuring the latest weight of each of a plurality of pigs at the time of estimation, or timing based on the timing for measuring the latest weight of each pig. The estimated desired timing is a timing at which the estimating unit 111 estimates the weight distribution at an arbitrary time point, and can be generated by the estimating unit 111. For example, a plurality of days from the day of weight measurement may be generated as the estimated desired timing based on the day of weaning. Further, the predetermined timing may be taken as the estimated desired timing.

Further, the estimation unit 111 estimates timing at which the estimated weight distribution satisfies a preset weight distribution. For example, the timing at which the estimated weight distribution satisfies the predetermined shipment condition may be estimated as the shipment expected date. The shipment condition is, for example, a condition that the weight of the entire group becomes maximum, a condition that the weight distribution falls in an appropriate weight band, and a condition that optimization of the weight distribution for shipment is achieved.

The estimation unit 111 can calculate basic statistics such as an average body weight, a mode (mode), a maximum value, a minimum value, a standard deviation, a kurtosis, and a skewness based on the estimated weight distribution. The weight distribution estimated by the estimating unit 111 is the weight distribution after the time point when the weight information of each livestock obtained by the weight information obtaining unit 112 is measured, but the weight distribution may be estimated back from the time point when the weight information of the livestock is measured.

The weight information obtaining unit 112 has a function of obtaining weight information by associating the weight of each of the livestock belonging to the management group with the timing (day) of measuring the weight of the livestock belonging to the management group. The information on the weight scale set in the pig house 301 described later can be directly obtained for each weight, and can be input by the user from the input unit 211 of the terminal device 201 described later, or can be input from weight information stored in another information management system (not shown). The weight information obtaining unit 112 stores the obtained weight information in the livestock information storage unit 121 in association with attribute information of a management group to be described later. Further, the weight information obtaining unit 112 may generate measurement timing information for presenting the user with timing for measuring the weight of the pig belonging to the management group after estimating the weight distribution in order to obtain the weight during the estimated weight distribution as the actual result weight. The weight information obtaining unit 112 can calculate the measurement timing information based on the last day of weight measurement of the pigs belonging to the management group. It is not necessary to associate the weight of each of the livestock belonging to the management group with the timing of measuring the weight of each of the livestock as the weight information, and for example, the weight of each of the livestock belonging to the management group may be associated with the timing of measuring the weight of each of the livestock as the management group in the summary data of the weights of the livestock.

The production information obtaining unit 113 has a function of obtaining history information indicating the raising history of pigs belonging to the management group. The feeding history information is information indicating the history of the feeding process of the pigs belonging to the management group, and includes, for example, the feeding history, the drug administration history, the history of movement of the pig house and the pig room, and the like. The obtained feeding history information is associated with the management group and stored as attribute information in the livestock information storage unit 121. The feeding history information can be obtained from information aggregated by another information management system (not shown). The feeding history information may be aggregated in the animal husbandry information management server 101 according to the present embodiment.

The management information obtaining unit 114 has a function of obtaining management information on the raising environment of pigs belonging to a management herd. The management information is information indicating the history of the environment of the pig room in the pig house 301, which is the raising place of the pigs belonging to the management group. Specifically, the information including the temperature and humidity and the time at which the temperature and humidity information associated therewith is obtained is information associated with the piggery ID and the pig room ID, but is not limited thereto. In addition, the management information includes information on the presence or absence of washing, disinfection, and drying of the pig room, and the time (lead time) required to carry out these. The management information obtaining unit 114 can obtain information from a temperature sensor and a humidity sensor provided in the pig house 301 through 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 as attribute information in the livestock information storage unit 121. The management information may be aggregated as history information in a separate information management system (not shown), or may be obtained from the information management system.

The turnover rate processing unit 115 has the following functions: the lead time for raising from the weaning day to the scheduled shipment day is calculated by the estimation unit 111 on the scheduled shipment date calculated by the management group unit, and the pig room turnover rate information is calculated by combining the management information (lead time required for washing, disinfecting, and drying) of each pig room obtained from the management information obtaining unit 114. The turnover rate (pig room turnover rate) indicates the number of times from raising to shipment of pigs in a predetermined period, and may be expressed as the number of times per year, for example.

The livestock information storage unit 121 has a function of storing the following information: attribute information indicating an attribute of a management herd which is a group for managing pigs; and weight information associating the weight of each of the plurality of pigs belonging to the management group with the date on which the weight was measured. The attribute information of the management group includes a 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, and a piggery ID and a piggery room ID indicating a piggery and a piggery room which are raising places of the pigs belonging to the management group. When treating a plurality of pig breeds, the attribute information may further include breed information (category information). Further, the history information obtained by the production information obtaining section 113 is stored as attribute information associated with the management group. Further, the management information obtained by the management information obtaining section 114 is stored as attribute information associated with the management group. When the weaning day of the pig is actually several days away from the weaning day of each of the pigs belonging to the management group, the approximate center day may be set as the representative value. In addition, the day of birth may be stored instead of the day of weaning of the pig, or both the day of weaning and the day of birth may be stored. Further, the livestock information storage unit 121 stores a condition (shipment condition) for the estimation unit 111 to estimate timing at which the estimated weight distribution satisfies a preset condition. This 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 given day using the obtained weight information of the pig. The mathematical model storage unit 122 can store a plurality of mathematical models and update the stored mathematical models. The mathematical model can be selected in accordance with the state of the attribute information by constructing a plurality of mathematical models using, for example, historical weight information and breed, work, illness, and pigsty environment information obtained in the past. Further, as for the mathematical model, an appropriate mathematical model can be selected according to the date (day age) from the weaning day. For example, the weight gain stage and the meat quality improvement stage in fig. 3 and 4, which will be described later, are changed on the dc day from the weaning day. The weight gain stage increases the weight, the meat quality improvement stage suppresses excessive weight gain and converges the weight deviation of each pig, and the accuracy of weight estimation can be improved by using different mathematical models. Further, by selecting the mathematical model corresponding to the breed information included in the attribute information of the management group to be estimated, for example, even when breeds different in weight increase degree with respect to the feeding amount are mixed, the estimation accuracy of the weight distribution can be improved.

As the mathematical model, for example, a bayesian estimation model can be used. The estimation unit 111 can update the mathematical model, for example, update the parameters, using the measured body weight (past performance body weight) obtained by the pig belonging to the management group to be estimated and the body weight (current performance body weight) newly obtained by using the bayesian estimation model. Therefore, the accuracy of estimation of future weight information of pigs belonging to the management group to be estimated can be improved. 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 apparatus 201 is an apparatus such as a PC, a smart phone, a tablet PC, and a mobile phone. The terminal apparatus 201 can access the livestock information management server 101 through dedicated application software installed in the terminal. Further, the stock information management server 101 may also be accessed using a running environment (API (application programming interface), platform, and the like) provided by the stock information management server 101.

The input section 211 has a function of inputting or selecting information by a user operation such as a keyboard, a mouse, a touch panel, or the like. Further, a touch panel integrated with the display portion 212 may be used, such as a smartphone, a tablet, a liquid crystal display in a PC, or an organic EL display. The input section 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 a user. The display device may be a display device independent of the terminal device 201, or may be a display device such as a liquid crystal display or an organic EL display in a smart phone or a tablet. The display unit 212 can display the weight distribution estimated by the estimation unit 111.

The terminal device 201 may be configured integrally with the stock information management server 101 without passing through the network NW.

< flow of treatment >

Next, the operation of the animal property information management system 1 according to the embodiment of the present disclosure will be described with reference to a flowchart shown in fig. 2.

In step S101, the weight information obtaining unit 112 obtains the weight of each livestock as weight information by associating the weight with the date on which the weight was measured. The weight information obtaining unit 112 stores the obtained 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 obtains attribute information of the management group from the livestock information storage unit 121.

In step S103, the estimating unit 111 estimates the following weight distribution using the attribute information of the management group obtained in step S102 and the weight information obtained in step S101: a weight distribution at a timing (estimation calculation timing) at which the latest weight of each of the pigs at the time of estimation is measured; and weight distribution at one or more subsequent occasions (estimated desired occasions). The estimation unit 111 can select a mathematical model for estimating the weight distribution from the mathematical model storage unit 122 in which a plurality of mathematical models are stored, based on the attribute information of the management group to be estimated. Further, the mathematical model may be changed according to an elapsed time from a weaning day associated with the management group to an estimated desired opportunity. The estimated weight distribution is stored in the livestock information storage unit 121 in association with the attribute information of the management group. The information of the estimation model used may be recorded in the mathematical model storage unit.

In step S104, the estimation unit 111 estimates a day when the weight distribution satisfies the shipment condition from the weight distribution estimated in step S103. That is, the shipment expected date can be estimated. Here, the shipment condition is a condition in which the weight is distributed in an appropriate weight band and the total weight of the group is maximized. This condition can be arbitrarily set by the user.

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

In step S106, the weight information obtaining unit 112 obtains, as the actual result weight, the weight information in which the weight of each livestock belonging to the management group measured after the estimation operation timing in step S103 is associated with the date when the weight is measured. The weight information obtaining unit 112 stores the obtained actual result 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 operation timing before step S103 and the actual weight obtained in step S106. Then, using the actual result weight obtained in step S106, estimation (re-prediction) of the weight distribution at the later estimation operation timing is performed. The estimated (re-predicted) weight distribution is stored in the livestock information storage unit 121 in association with the attribute information of the management group. The information of the estimation model used may be recorded in the mathematical model storage unit.

In step S108, the estimating unit 111 estimates and updates the day on which the weight distribution satisfies the shipment condition 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 weight distribution estimated in the previous time. Further, the shipment predicted date estimated in step S108 can be displayed.

< weight Change in pig >

Next, the change in weight of the pig will be described. Fig. 3 is a graph showing the transition of the change in weight of a pig handled by the livestock property information management system according to the embodiment of the present disclosure. The horizontal axis of fig. 3 represents the number of days (day age) from the weaning day of a sow or the like (may be a nursing apparatus), and the vertical axis represents the body weight.

As shown in FIG. 3, the pigs (non-breeding pigs) were shipped after the weight gain stage and the meat quality improvement stage. The weight gain phase is the phase of weight gain within a specified period after weaning. In addition, the meat quality improvement stage is a stage in which excessive weight increase is suppressed after the predetermined period is over, and the weight variation of each pig is converged to bring the weight distribution within a predetermined range. The stage from weaning day to day-old dc is a weight gain stage, and the stage from day-old dc to shipment day-old ds is a meat quality improvement stage. As described above, since the non-breeding pigs were managed by the herd, the weight of the pigs belonging to the managed herd was expressed as the weight distribution. The weight distributions 151m to 168m of fig. 3 show the age in days progression of the weight distributions of pigs belonging to the management group in boxplots. In addition, the

weight distributions

151m, 161m, and 168m are also shown in conceptual views showing the frequency distribution of the number of pigs per weight.

As shown in fig. 3, the livestock grower increased the weight of the pig to approach the shipment target weight w1 of the pig during the weight gain stage, and raised the pig so that the weight distribution approaches the shipment target weight w1 during the meat quality improvement stage. As shown in a region 180, each pork pig is "on pole" if its weight falls within a range specified as "on pole" centered on the shipment target weight w1, and is classified as "on", "medium", and "normal" according to the expansion of the weight range. Ranges that do not meet this rating are "out of specification". Note that the grade of meat quality is not determined only by the body weight, but is on the premise that at least the body weight falls within a predetermined range. That is, it is necessary to raise pigs in the weight gain stage and meat quality improvement stage so that the weight of the pigs falls within the range of the grade (appropriate weight band).

Fig. 4 is a graph showing the change in weight of pigs in the middle of feeding and the transition of the estimated predicted value of the change in weight. Fig. 4(a) is a graph of the predicted value estimated when the estimation operation timing is on day p1, and fig. 4(b) is a graph of the predicted value estimated again when the estimation operation timing is on day p2 after day p 1. In fig. 4(a) and 4(b), the horizontal axis represents the number of days counted from the weaning day of a sow or the like (may be a nursing machine), and the vertical axis represents the body weight, as in fig. 3.

In fig. 4(a), weight distributions 151m to 158m are boxplots showing the actually measured weight distributions of pigs belonging to the management herd. The weight distributions 159p to 168p show, in boxplot lines, the weight distributions of the predicted values of the plurality of estimated desired timings estimated on day p 1. In addition, the weight distribution 151m is also shown as a graph showing the frequency distribution of the number of pigs per weight based on the actual measurement value. The

weight distributions

161p and 168p are also conceptual diagrams showing the frequency distribution of the number of pigs per weight based on the estimated values.

In fig. 4(b), the weight distributions 151m to 161m show the actually measured weight distributions of the pigs belonging to the management group in boxplots. The weight distributions 159p to 168p are box line graphs showing the weight distributions of the predicted values at a plurality of estimated desired timings estimated on day p 1. Further, the weight distributions 162p 'to 168 p' show the weight distributions of the predicted values of the plurality of estimated desired timings estimated on day p 2. The weight distributions 162p 'to 168 p' show the weight distributions at the same timings as the weight distributions 162p to 168p, respectively, but the weight distributions 162p 'to 168 p' are described so as to be slightly shifted to the right in order to improve the visibility of the figure. In addition, the weight distribution 151m is also shown as a graph showing the frequency distribution of the number of pigs per weight based on the actual measurement value. The

weight distributions

161m and 161p are also shown in the form of conceptual diagrams showing the frequency distribution of the number of pigs per weight from the actual measurement value and the estimated value. Further, the

weight distributions

168p and 168 p' are also shown as conceptual diagrams respectively showing the frequency distribution of the number of pigs per weight based on the estimated value of day p1 and the frequency distribution of the number of pigs per weight based on the estimated value of day p 2.

As shown in fig. 4(b), when the

weight distributions

161m and 161p are compared, the weight distribution 161m as the actual measurement value is heavier as a whole than the weight distribution 161p estimated on day p1, and the actual measurement value deviates from the estimated value. Therefore, the weight distributions 162p 'to 168 p' are predicted weight distributions which are estimated again by using a mathematical model updated with the weight newly obtained on day p2 in order to eliminate the deviation. Therefore, the accuracy of the weight distribution as the estimation of the age of day ds on the shipment predicted day is improved.

Specifically, the number of days can be changed by advancing or delaying the date by clicking the left and right buttons of the display of "expected date of shipment" with the mouse or the like of the input unit 211. This allows the user to know the weight distribution and the like before and after the shipment expected date estimated by the estimation unit 111.

The display area 213d is an area for displaying the distribution state of the prediction value of the rank weight score for the "predicted date of shipment" of the pigs belonging to the management group selected in the display area 213 a. Specifically, in fig. 5, pigs belonging to the "on pole" grade weight are predicted to be 0, and the weight is shown to be 0 kg. Likewise, pigs belonging to the "upper" grade weight were predicted to be 4 heads, and the weight was displayed as the total weight of the 4 heads. Pigs with weights falling on the "medium" scale were predicted to be 6 heads and the weights are shown as the total weight of the 6 heads. Pigs of weight belonging to the "normal" grade were predicted to be 10 heads and the weight was shown as the total weight of 10 heads. Pigs that were predicted to be of a weight of "off grade" were 1 head and the weight was displayed as the weight of 1 head. The total number of heads belonging to the management group and the total weight are shown in the lower stage.

The display area 213e is an area showing the basic statistics calculated from the data of the distribution state of the prediction values by the rank-weight shown in the display area 213 d. The basic statistics show the mean body weight, mode, standard deviation, kurtosis, and skewness of the predicted values by rank weight.

The display area 213f is an area in which a histogram of the distribution state of the prediction values of the gradation weight scores shown in the display area 213d and a pie chart showing the ratio of the gradation weights are displayed.

The user can select a management group by operating the input unit 211 while looking at the display screen 213 displayed on the display unit 212 of the terminal device 201, and know the predicted weight on the expected shipment date as the distribution of the management group.

(Re-prediction screen of weight distribution for scheduled shipment date)

Fig. 6 is a screen showing the weight distribution estimated by the estimating unit 111 in the animal husbandry information management system according to the embodiment of the present disclosure. Fig. 6 is a screen in which the weight distribution (second body weight distribution) on the shipment expected date estimated (re-predicted) by the estimation unit 111 at the timing after the weight measurement (second estimation operation timing) after the estimation of the weight distribution at the timing (first estimation operation timing) in fig. 5 is performed is displayed together with the weight distribution (first body weight distribution) at the first estimation operation timing. Specifically, the weight distribution when the weight distribution is re-predicted on the "present" day p2 (the second estimation calculation timing) after p1 (the first estimation calculation timing) which is the "previous" weight distribution prediction day in fig. 4(b) is shown. As in fig. 5, a display screen 214 is displayed on the display unit 212 of the terminal device 201. The display screen 214 is composed of display regions 214a to 214g described below.

Similarly to display area 213a of fig. 5, display area 214a is an area for displaying a management group list such as the number of management heads for each management group and the expected date of shipment. The management group list shown in the display area 214a is a list displayed based on the attribute information of the management group stored in the livestock information storage unit 121. The management group list is arranged from the left by items of "selection column", "piggery ID", "management head number", "date scheduled for shipment", "age scheduled for shipment, and" total scheduled for shipment ", and is displayed for each management group in the vertical direction. In FIG. 6, pigs of the management group having "pig house ID" of C01 and "pig house ID" of P9-015 were selected.

The display area 214b is an area for displaying the "piggery ID", the pig house ID, and the weaning day, which are the locations where pigs of the management group selected from the management group list are fed.

The display area 214c is an area in which the "date of prediction history" as the timing at which the past weight distribution estimation was performed can be specified. The "date of the prediction history" may be selected from a drop down menu next to the date.

The display area 214d is an area in which the following is displayed: a distribution state of the prediction value of the rank weight score on the scheduled shipment day estimated at the past timing (first estimation calculation timing) selected in the "date of prediction history" selected in the display area 214c of the pig belonging to the management group selected in the display area 214a ("last" column); and the distribution state of the prediction value of the grade weight score by shipment predicted day at the current time (second estimation calculation timing) (column "this time"). Specifically, in fig. 6, the pigs that "last time" predicted a weight belonging to the "on pole" grade were 0, and the weight was displayed as 0kg, while "this time" was updated to predict 1. Likewise, pigs belonging to an "upper" grade weight were predicted to be 4 in the "last time" and the weight was displayed as the total weight of 4, while 5 in the "present time". Pigs belonging to the "normal" grade weight were predicted to be 10 on "last time" and the weight was displayed as the total weight of 10, whereas 8 were predicted on "this time". Pigs belonging to the "off-grade" weight were predicted to be 1 in the "last time" and the weight was displayed as the weight of 1, and 0 in the "present time". The total number of heads belonging to the management group and the total weight are shown in the lower stage. In this way, it can be known that the body weight distribution predicted this time is more distributed in the middle than the body weight distribution predicted last time.

The display area 214e is an area showing the basic statistics calculated from the data of the distribution state of the prediction values by rank weight shown in the display area 214 d. The basic statistics show the mean body weight, mode, standard deviation, kurtosis, and skewness of the predicted values by rank gravities. Similarly to the display area 214d, the following are displayed: basic statistics of shipment forecasted days displayed at the date of the forecast history selected in display area 214c ("last" column); and basic statistics of the shipment predicted date at the current time (latest date of date information of weight information) ("this time" column).

The display area 214f is an area that displays a histogram of the distribution state of the prediction values of the grade-by-grade weight shown in the display area 214d, and a pie chart showing the ratio of the grade weights. In the histogram, the horizontal axis represents the weight level (kg) and the vertical axis represents the frequency (head number). Similarly to the display area 214d, the following are displayed: histograms and pie charts of shipment forecasted days displayed at the date of the forecast history selected in display area 214c ("last" column); and a histogram and pie chart for the shipment forecasted day at the current time point (the "this time" column).

The display area 214g is an area in which buttons for displaying a feeding log and an environment log are displayed. When a button of the feeding log is clicked with a mouse, feeding history information indicating the feeding history of the pigs belonging to the selected management group is displayed. Further, when a button of the environment log is clicked with a mouse, a history of management information of the pig room in the pig house 301 of the raising place of the pig belonging to the selected management group is displayed.

As described above, the livestock-dedicated worker as the user can compare the weight distribution on the scheduled shipment day estimated at the past predetermined timing (for example, p1 day/first estimation operation timing of fig. 4 (b)) with the weight distribution on the scheduled shipment day estimated at the subsequent timing (for example, p2 day/second estimation operation timing of fig. 4 (b)) via the screen of fig. 5. Further, by checking the history of the feeding history and the history of the management information during this period (period from the first estimation operation timing to the second estimation operation timing), it is possible to provide information that supports the feeding behavior (including the improvement behavior) performed by the animal husbandry worker during this period and the verification behavior of the change in the weight distribution.

It is to be noted that, in fig. 6, the first body redistribution and the second body redistribution estimated at the first estimation calculation timing and the second estimation calculation timing are shown in a comparable manner, but the display section 212 may also display two or more body redistribution estimated at two or more plural estimation calculation timings in a comparable manner. This allows the user to know the transition of the weight distribution for each estimation calculation timing.

(Notification screen on day of weight measurement)

Fig. 7 is a screen for notifying the weight measurement of the predetermined day based on the measurement timing information generated by the weight information obtaining unit 112 in the livestock property information management system according to the embodiment of the present disclosure. In order to improve the accuracy of estimation of the weight distribution by the mathematical model, it is desirable to obtain actual measurement values of the weights at arbitrary timings of the estimation. Therefore, the timing of the weight measurement is notified on the screen. The timing of measurement of the actual measurement values may be changed depending on the age of the day. For example, the weight information obtaining unit 112 generates the measurement timing information so as to decrease the measurement interval or decrease the measurement interval, that is, increase the frequency of measurement, at the day of age when the weight change is large. Fig. 7 is a display screen 215 displayed on the display unit 212 of the terminal device 201, as in fig. 5 and 6. The display screen 215 is composed of display regions 215a to 215f described below. The display regions 215b to 215f are the same as the display regions 213b to 213f in fig. 5, and therefore, the description thereof is omitted.

Fig. 7 is a screen showing the predicted days of weight measurement for each management group. The display area 215a is an area for displaying a management group list such as the number of management heads and scheduled shipment days for each management group. The management group list shown in the display area 215a is arranged from the left by items of "selection column", "piggery ID", "weaning elapsed day", "day of last weight measurement", "number of days of next weight measurement predicted", and "number of days to next weight measurement", and is displayed for each management group in the vertical direction. In FIG. 7, pigs of the management group having "pig house ID" of C01 and "pig house ID" of P9-015 were selected.

The information of each item displayed is information stored in the livestock information storage unit 121 or information determined based on the information. The "last-weight-measurement day" indicates the latest date of the date information of the weight information stored in the livestock information storage unit 121. The "elapsed day of the last weight measurement" is the number of days of the difference between the date (present) shown in fig. 7 and the "elapsed day of the last measurement". The "next measurement scheduled day" is the date determined by the measurement timing information generated by the weight information obtaining unit 112. Specifically, for example, the date is determined by adding a predetermined period to "last measurement day". The "number of days until the next weight measurement" is the number of days of difference between the date (present) shown in fig. 7 and the "predicted day of the next measurement". In the case where the next measurement predicted day has elapsed, the "next measurement predicted day" may be displayed as negative, the color of the display may be changed, or the user may be notified of an alarm separately.

In this way, the user can know the timing of the weight measurement of the pigs belonging to each management group on the display screen of fig. 7, and can prevent the omission of the regular weight measurement. Therefore, the accuracy of the weight distribution estimated using the mathematical model can be improved.

(display of turnover rate in pig room)

In the pig room, if the pig is shipped, the next pig can be raised. Therefore, by counting the shipment ages in days in each pig room, the turnover rate in each pig room can be calculated.

Fig. 8 is a screen showing the pig room turnover rate calculated by the turnover rate processing unit 115 in the livestock information management system according to the embodiment of the present disclosure. Fig. 8 is a display screen 216 displayed on the display unit 212 of the terminal device 201, as in fig. 5 to 7. The display screen 216 is composed of display regions 216a to 216e described below.

The display area 216a is an area for displaying the overall turnover number performance of the farm. The overall farm turnover is shown from the left, the piggery-piggery room and turnover for the maximum turnover in the farm are shown in the middle, and the piggery-piggery room and turnover for the minimum turnover in the farm are shown on the right.

The display area 216b is an area that displays a list showing the turnover rates of each pig room. The list of turnover ratios shown in the display area 216b is arranged from the left by items of "selection column", "piggery ID", "piggery room ID", "recent turnover ratio", "shipment age", "past turnover ratio", and "past average distribution", and is displayed for each piggery room in the vertical direction. In FIG. 8, the pig house with the pig house ID A04 and the pig house ID P2-010 was selected. The "recent turnover rate" is a turnover rate calculated from the shipment age of days predicted based on shipment from each pig house. Past turnover rates show past turnover rates for each swine room, and show maximum, average, and minimum turnover rates, respectively. "past average distribution" means the average of the past turnover number distribution values.

The display area 216c is an area that displays a graph of the turnover rate of each pig room of the entire farm. The horizontal axis represents the recent turnover number, and the vertical axis represents the turnover number averaged in the past. Each circle shown represents a pig room, respectively, and the diameter of the circle corresponds to the number of management heads in the pig room. In fig. 8, the hatched circle indicates the selected pig room in the display area 216 b.

The display area 216d is a graph showing the time course of the turnover rate, the upper stage shows the turnover rate of the entire farm, and the lower stage shows the turnover rate for each piggery.

The display area 216e is an area where a map showing the layout of the entire farm, the layout of the pigsty in the farm, and the layout of the pigsty in the pigsty is displayed. For example, it is possible to visually recognize from the map which pig room of which pig house in the farm the pig house selected in the display area 216b is.

In this way, the user can provide pig room turnover rate information, which is one of production performance information (KPI) of the animal husbandry (user), through the display screen 216. In addition, by rapidly identifying a pigsty with high production performance and a pigsty with low production performance, a service improvement point can be identified, and a pigsty which should be improved in service in full can be extracted.

As described above, in the livestock property information management system 1 according to the embodiment of the present disclosure, by obtaining the weight information of each of the multiple pigs belonging to the management herd and using the obtained weight information of each of the multiple pigs and the attribute information of the management herd including information on the weaning day of the multiple pigs belonging to the management herd, it is possible to estimate the weight distribution of the pigs belonging to the management herd at the timing of the scheduled shipment date. The livestock industry can make business plans and delivery plans for increasing profits by knowing the estimated weight distribution.

In the above embodiment, the estimated desired timing is selected by the system, but may be specified by the user. For example, when the user inputs the scheduled shipment date from the input unit 211 as the estimated desired timing, the estimating unit 111 can estimate the weight distribution of the multiple pigs belonging to the management group on an arbitrary scheduled shipment date at a predetermined estimated calculation timing for estimation, using the weight information of each pig obtained by the weight information obtaining unit 112 and the attribute information of the management group including information on the weaning date of the multiple pigs belonging to the management group. The user can improve the business plan by determining the expected shipment date in advance and knowing the weight distribution of the expected shipment date at the current time (calculation and estimation timing).
