Abstract
Description
Technical Field
[0001] This invention relates to pig farming technology, specifically to a refined management device and system for pig feeding. Background Technology
[0002] In a modern, large-scale pig farming system, firstly, precise nutritional regulation and management to reduce feed loss and improve feed conversion efficiency directly impacts production cost control; secondly, establishing an individualized health monitoring mechanism to promptly identify abnormal physiological or behavioral signals is fundamental to ensuring herd stability and reducing disease losses; thirdly, relying on traceable and precise growth performance data (such as daily weight gain and feed conversion ratio) for breeding pig selection is the core path to drive genetic improvement of the herd and enhance the production potential of offspring; finally, shortening the non-productive days of sows through refined management and improving their lifetime productivity is key to unlocking the value of the reproductive process.
[0003] Most existing farms still use the traditional free-feeding model, where feed is continuously supplied to the troughs and all pigs share the feed indiscriminately. This makes it difficult to track individual feeding behavior. Due to the lack of individual identification and accurate measurement methods, farmers can only rely on manual observation and group data to estimate the health and growth of pigs. This method is inefficient and seriously lagging. For example, sick pigs are often only discovered when obvious clinical symptoms appear, missing the best time for intervention. At the same time, the selection of breeding pigs relies on appearance or the average feed conversion ratio of the group, lacking accurate individual performance data to support it, and the scientific nature of the selection is insufficient. For breeding sows, whether they are pregnant after mating mainly depends on external observation and experience judgment, making it difficult to make early and accurate diagnoses through objective and continuous changes in weight data. This leads to the unintentional prolongation of the non-pregnant period, which seriously affects the overall reproductive efficiency of the sow herd and the economic benefits of the farm. Summary of the Invention

[0017] Furthermore, the background management system is also configured to: monitor the feeding time interval of each individual pig, and generate an early warning signal containing the corresponding pig's identity information when the time interval exceeds a preset threshold.
[0018] Furthermore, the background management system is also configured to: based on the feed conversion ratio data of individual fattening pigs, select individuals that meet preset performance indicators as candidates for breeding pigs.
[0019] Furthermore, the background management system is also configured to: determine whether the individual sows are in the expected pregnancy weight gain state based on continuous monitoring and analysis of their weight data, and generate processing prompts for individuals that are determined not to be in the expected state.

Detailed Implementation
[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0039] As attached Figure 1 To be continued Figure 5 As shown:
[0040] Example 1:
[0041] The present invention provides a refined management device for pig feeding, including a pig trough 1, which is a long strip-shaped trough with a recessed bottom forming a channel 101 for storing feed. The pig trough 1 is placed on the weighing platform of a first electronic weighing device 2 through a support structure at its bottom, so that the first electronic weighing device 2 can accurately measure the total weight of the entire trough and the feed inside.
[0042] On both sides of the outer wall of the pig feed trough 1, two vertical fixed plates 3 are symmetrically fixed by welding or bolts. A sufficiently sturdy metal pedal 4 is horizontally fixed between the two fixed plates 3, forming a fixed feeding station independent of the ground. The second electronic weighing device 5 is installed below the pedal 4, and its weighing platform directly supports the pedal 4. It is used to measure the weight of the pig standing on the pedal 4 and the sum of the weight of the pig feed trough 1 and its contents transmitted through the fixed plates 3. Since the fixed plates 3 are rigidly connected to the pig feed trough 1, the weight transmitted is certain and constant and can be deducted through calibration.
[0043] The feed pipe 6 is inserted at an angle and fixed to the rear side wall of the pig feed trough 1. Its lower end opening is suspended above the trough 101 to form the discharge port 7. The feed from the external feeding system can be sent into the trough 101 through the feed pipe 6.
[0044] The core part of the feeding control component 8 is installed inside the feed pipe 6 near the outlet 7. The connecting column 801 is rotatably connected to the wall of the feed pipe 6 via a bearing. Its lower end extends into the pipe cavity and is fixedly connected to the first baffle plate 802. The connecting shaft 804 is rotatably connected to the hollow part inside the connecting column 801 via a bearing. It is fixedly connected to the second baffle plate 805. The shapes of the first baffle plate 802 and the second baffle plate 805 are complementary. When the two are close together, they can tightly seal the cross section of the outlet 7. The upper end of the connecting column 801 extends out of the feed pipe 6 and is coaxially fixed to the first toothed ring 803. The upper end of the connecting shaft 804 also extends out of the connecting column 801 and is coaxially fixed to the second toothed ring 806.
[0045] The driving component 807 is fixed on the outer wall of the conveying pipe 6. The cylinder of the electric push rod 8071 is fixed, and the end of its telescopic rod is fixed to a U-shaped movable frame 8072. On the two inner arms of the movable frame 8072, the first rack 8073 and the second rack 8074 are installed in a staggered manner. The first rack 8073 meshes with the first toothed ring 803, and the second rack 8074 meshes with the second toothed ring 806. When the telescopic rod of the electric push rod 8071 is retracted, it pulls the movable frame 8072 to retract. The first rack 8073 drives the first toothed ring 803 to rotate, and the second rack 8074 drives the second toothed ring 806 to rotate in the opposite direction, thereby separating the first baffle plate 802 and the second baffle plate 805 from each other and opening the discharge port 7. Conversely, when the electric push rod 8071 is extended, it pushes the movable frame 8072 forward and drives the two baffle plates to close.
[0046] An electronic ear tag reader 10 (such as an RFID reader) is installed at the top front of the pig feed trough 1, facing the typical position of the pig's head when it is eating, and is used to read the readable electronic ear tag 11 (i.e., RFID ear tag) implanted in the pig's ear.
[0047] The data transmission module 9 is also installed on the pig feed trough 1. It is connected to the control line of the electronic ear tag reader 10, the electric push rod 8071, the signal output terminal of the first electronic weighing device 2 and the second electronic weighing device 5 through its internal circuit. It is responsible for collecting data, receiving instructions and realizing communication with the remote server.
[0048] Working principle: When a pig wearing an ear tag walks onto the pedal 4 and extends its head near the feed outlet 7, the electronic ear tag reader 10 reads its unique ID. This ID is sent to the controller (which can be a local controller or a backend system) via the data transmission module 9. After the controller verifies the ID's validity, it performs the following actions: records the readings of the first electronic weighing device 2 and the second electronic weighing device 5 at this time, sends a signal to the electric push rod 8071 to open the feed baffle, allowing feed to flow out and the pig to begin feeding. After a preset time or when the system determines that feeding has basically ended based on weight changes, the controller instructs the electric push rod 8071 to close the feed baffle and stop feeding. It then records the readings of the first electronic weighing device 2 and the second electronic weighing device 5 again. The data packet of this feeding event is uploaded via the data transmission module 9. The accurate amount of feed consumed in this event can be obtained through calculation. By calculating and combining the tare weight calibrated by the system, the estimated weight of the pig before and after feeding can be obtained, which is used to calculate the daily weight gain.
[0049] Through the separate dual weighing unit, while the first electronic weighing device 2 measures the total weight of the feed trough, the second electronic weighing device 5, which is rigidly connected to the feed trough, simultaneously acquires a composite weight signal including the weight of the pigs. This physical structure arrangement allows for indirect and stress-free weight estimation without transferring the pigs during a single feeding activity, solving the problem of dynamic weighing. At the same time, the feeding control component 8 integrated into the feed pipe 6 adopts a mechanical structure in which the electric push rod 8071 drives the gear rack to drive the double baffle plate, achieving accurate and reliable control of feed output. It is also compact and durable. The entire device modularly integrates identification, quantitative feeding, and weight sensing into the pig feed trough 1, constructing a stable and efficient on-site data acquisition terminal, laying a solid physical foundation for subsequent data analysis.
[0050] Example 2:
[0051] As attached Figure 6 As shown, a refined management system for pig feeding is provided. After the system is started and initialized, the background management system (deployed in the cloud or on a local server) is in standby mode.
[0052] Once the device triggers a feeding event and completes data collection and uploading, the backend management system operates according to the following process:
[0053] Data Reception and Parsing: The system receives data packets and parses the newborn pig's identification ID, event timestamp T, and two pairs of weight data: the first electronic weighing instrument reading at the initial feeding moment. 5. Reading of the second electronic weighing instrument And the reading of the first electronic weighing instrument 2 at the end of feeding. 5. Reading of the second electronic weighing instrument .
[0054] Data Association and Storage: The system uses the identity ID as the primary key to search for or create corresponding individual pig files in the database, storing the timestamp T and weight data tuples for this event. It is stored as a record in the time-series data table of the archive.
[0055] Core Computing:
[0056] Calculation of feed intake per feeding:
[0057] Feed intake this time The amount of weight reduction in the feed trough before and after feeding is determined by the following formula: ,in, This indicates the amount of food consumed in this instance, usually expressed in kilograms (kg).
[0058] Pig weight estimation:
[0059] To obtain accurate pig weight, the constant tare weight of the feed trough and its fixed connecting parts needs to be deducted. During system initialization or calibration, the system calculates the calibration tare weight constant by collecting readings from the first electronic weighing device 2 and the second electronic weighing device 5 under no-load conditions (no pigs on pedal 4). .
[0060] Estimated weight of pigs before feeding The calculation formula is as follows:
[0061] Estimated weight of pigs after feeding The calculation formula is as follows:
[0062] Normally, The current weight of the pigs is updated following this feeding event. This is the system calibration constant, expressed in kilograms (kg).
[0063] Daily weight gain calculation:
[0064] Daily weight gain of pigs The result is calculated by comparing the last weight on two consecutive days. Let the weight be... The last recorded weight for the day was , No. The last recorded weight for the day was Then the first The daily weight gain is:
[0065] Feed conversion ratio calculation:
[0066] Stage feed conversion ratio It is a key indicator for evaluating feed conversion efficiency, calculated at a certain stage (e.g., from body weight). Growing to weight The feed conversion ratio is calculated using the following formula: ,in, This represents the total amount of food consumed during this stage. This represents the net weight gain during this phase.
[0067] Intelligent analysis and decision support:
[0068] Health alert: The system retrieves the timestamp of the last feeding event for this ID. Calculate feeding interval ,like The value exceeds the warning threshold set for this type of pig (such as fattening pigs and lactating sows). For example, if the interval is 12 hours, an early warning process will be automatically triggered.
[0069] Performance-based breeding: The system includes a breeding analysis module. When fattening pigs reach the evaluation point, the module retrieves their feed conversion ratio (FCR) throughout the entire breeding process. and average daily weight gain The data is sorted within a defined group or filtered by setting performance thresholds.
[0070] Reproductive status assessment aids: The system establishes an independent monitoring task for each bred sow, continuously tracking its daily weight data after mating, plotting weight change curves, and using a "normal pregnancy weight gain model" built into the system or established through machine learning to describe the expected weight. ,in To determine the number of days post-mating, by comparing actual body weight. Compared with expected values, for example, calculating the deviation. If for several consecutive days If the value is significantly below zero or below a set threshold, the system will mark the sow as "suspected non-pregnant".
[0071] Data visualization and reporting: Data from all individuals and groups, including but not limited to... , , , Key indicators such as these can be dynamically displayed in chart form on the dashboard interface of the back-end management system, and standardized production performance analysis reports can be generated regularly.
[0072] By integrating a readable electronic ear tag 11 for identification, a linked control feeding mechanism, and a separate dual weighing unit, the system automatically and synchronously completes identity binding, feed consumption measurement, and weight change monitoring during each feeding behavior of pigs, constructing a complete individual data chain. Based on this data stream, by monitoring feeding intervals in real time, it automatically issues early warnings for individuals that abnormally stop feeding, achieving early disease detection and isolation. Based on long-term accumulated accurate feed conversion ratio and daily weight gain data, it provides objective and quantitative decision-making basis for selecting high-yielding breeding pigs, significantly improving the scientific nature and efficiency of breeding. By continuously analyzing the weight gain curve of sows after mating and intelligently comparing it with pregnancy models, it provides key data support for early pregnancy diagnosis, which helps to facilitate timely re-mating or treatment, minimize the non-pregnant period, and improve sow utilization. This technical solution upgrades traditional experience-based, group-based breeding management into a data-driven, individualized intelligent management closed loop.
