Description

Technical Field

[0001] This invention relates to the field of intelligent breeding management technology, and in particular to a method and device for integrated planning and scheduling of pig production and herding. Background Technology

[0002] In modern intensive pig farming, regrouping management is a crucial aspect affecting breeding efficiency and animal welfare. As relatively closed, high-density farming units, integrated pig pens involve the movement of pigs across pens, units, and even farm areas during regrouping. This easily disrupts existing environmental barriers, increasing the risk of external pathogen infection and internal cross-infection. Traditional regrouping management relies heavily on manual experience and judgment, leading to problems such as delayed decision-making and inconsistent standards. It also makes it difficult to track the health status and reproductive potential of each pig in real time, resulting in misallocation of pen resources, increased risk of disease spread, and even affecting the optimal utilization rate of breeding pigs.

[0003] While some automated regrouping devices in the current technology achieve basic grouping through RFID or simple weight monitoring, their technical solutions have the following shortcomings: First, they lack in-depth analysis of multidimensional health indicators of pigs, such as data on body surface damage, movement posture, feeding behavior, and disease detection, which are not effectively integrated; second, they do not incorporate sow reproductive performance parameters (such as live pig count, number of piglets, parity performance, lactation capacity, and genetic index) into the dynamic evaluation system; third, they do not fully consider the pathogen carrier status or health risk level of pigs during the regrouping decision-making process, which can easily lead to the mixing of pigs with different health conditions and cause cross-infection; and fourth, they lack dynamic optimization scheduling of regrouping routes, loading plans, and pen allocation, making it difficult to achieve efficient resource allocation and closed-loop management of biosecurity.

[0004] Therefore, how to provide a migration method that can integrate multidimensional health monitoring and reproductive performance analysis, and combine pathogen-carrying status for dynamic planning and scheduling, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a method and device for integrated planning and scheduling of pig herding in pig production. By integrating health monitoring and reproductive performance data, pigs are comprehensively rated and prioritized, eliminating reliance on single indicators or human experience in herding decisions and enabling accurate identification of high-value breeding pigs and sick pigs requiring isolation. During the pen-to-vehicle loading process, the method considers the pigs' pathogen-carrying status or health risk level, prioritizing the merging of pigs in similar states to prevent mixing of pigs with different health conditions and strengthen biosecurity control. Target pens are dynamically allocated and herding paths are generated based on the loading plan and pen layout, improving pen turnover efficiency and reducing pig stress and environmental control delays caused by herding chaos. Through scientific planning of the herding process, the risk of disease outbreaks and treatment costs are reduced, ensuring smooth connection between various breeding stages and improving pig survival rates and overall breeding efficiency.

[0006] In a first aspect, the present invention provides a method for integrated planning and scheduling of pig farming and herding, comprising: Obtain health monitoring data and reproductive performance data of pigs to be transferred; Based on health monitoring data and reproductive performance data, each litter of pigs is comprehensively rated to generate a priority transfer list; Based on the priority transfer list, combined with the pathogen carrier status and / or health risk level of the pigs, a merging and loading plan is dynamically generated according to the principle of prioritizing the merging of pigs with the same status. Based on the pen loading plan, combined with the integrated pen layout and comprehensive rating results, target pens are dynamically allocated, and transfer routes and loading instructions are generated.

[0007] In some preferred embodiments of the present invention, the health monitoring data includes at least one of the following: abnormal body temperature, skin lesions, abnormal movement posture, decreased feeding behavior, and disease detection results.

[0008] In some preferred embodiments of the present invention, reproductive performance data include at least one of the following: number of live offspring, number of offspring with offspring, parity birth performance, lactation capacity, and genetic index.

[0009] In some preferred embodiments of the present invention, the step of comprehensively rating each litter of pigs based on health monitoring data and reproductive performance data to generate a priority transfer ranking list includes: Arrange all the nests to be transferred in descending order of the number of live offspring, and then in descending order of the number of offspring with offspring. Based on the target number of sows to be added to the group, healthy sows are selected from the top-ranked litters in turn until the preset target number of sows is reached. Starting from the location of the last selected sow pen, select boars one by one upwards until the preset target number of boars is reached; Based on the selection of pigs, the litter is marked as selected only for sows, selected for the whole litter, or other, and is assigned a three-level rating of A, B, or C accordingly.

[0010] In some preferred embodiments of the present invention, the step of dynamically generating a pens-merging and loading plan based on a priority transfer sorting list, combined with the pathogen carrier status and / or health risk level of the pigs, and according to the principle of prioritizing merging those with the same status, includes: The rated nests are then divided into nursing units, maintaining the priority order; Based on the pathogen carrier status and / or health risk level of the pigs, pens of the same status should be combined, and pens of different statuses should not be mixed. Priority will be given to merging only sow pens with a rating of A, and merging will be carried out in descending order of ranking, with the number of pens per vehicle not exceeding the set threshold. If there are not enough Class A parking spaces to fill one car, then supplement them from the selected parking spaces rated B according to their ranking. The remaining slots are merged in order of priority to generate complete train numbers.

[0011] In some preferred embodiments of the present invention, the pathogen-carrying status includes: the result of PRRS antigen detection; according to the principle of preferential merging of the same status, the following is included: merging PRRS negative circles with PRRS negative circles, merging PRRS positive circles with PRRS positive circles, and prohibiting the mixing of PRRS negative circles and PRRS positive circles.

[0012] In some preferred embodiments of the present invention, the step of dynamically allocating target fields includes: The integrated housing is divided into Grade A pens and ordinary pens, and the pens rated A are given priority to be assigned to Grade A pens; If the number of Grade A nests exceeds the capacity of Grade A spaces, then the number of Grade A spaces will be expanded according to the principle of symmetry. Within the same dormitory unit, allocation is based on pathogen carrier status and / or health risk level; If the number of nests to be transferred exceeds the total number of spaces, then additional nests will be allocated to each individual shed according to the principle of equal distribution.

[0013] In some preferred embodiments of the present invention, the method further includes: Before the regrouping is carried out, a regrouping coordination meeting is held based on the generated regrouping path and the pig loading execution instructions to clarify the personnel movement, disinfection process and isolation measures; During the transfer process, suspected sick pigs are sorted in real time and guided to isolation and observation pens; After the pigs are transferred to a new group, their feed intake, daily weight gain, and mortality rate are recorded and fed back to the system to optimize subsequent scheduling strategies.

[0014] In some preferred embodiments of the present invention, the method further includes: Before transferring the pigsty, conduct environmental pre-adjustment and equipment maintenance, including at least one of the following: water line disinfection, feed line testing, and temperature and humidity control. Acidified drinking water and anti-stress interventions were used during the regrouping process to reduce stress response in pigs.

[0015] Secondly, the present invention provides an integrated pig farming and herding planning and scheduling device, comprising: The pig herd information acquisition module is used to acquire health monitoring data and reproductive performance data of pigs to be transferred. The regrouping and sorting module is used to comprehensively rate each litter of pigs based on health monitoring data and reproductive performance data, and generate a priority regrouping list. The pen-to-pen loading solution processing module is used to dynamically generate a pen-to-pen loading solution based on the priority transfer sorting list, combined with the pathogen carrier status and / or health risk level of the pigs, and according to the principle of prioritizing the merging of pigs with the same status. The execution module is used to dynamically allocate target pens and generate transfer routes and loading instructions based on the pen loading plan, the integrated pen layout, and the comprehensive rating results.

[0016] This invention brings the following beneficial effects: This invention provides a method and apparatus for planning and scheduling pig herding in an integrated pig production facility. The method includes: acquiring health monitoring data and reproductive performance data of pigs to be herded; comprehensively rating each litter of pigs based on the health monitoring data and reproductive performance data to generate a priority herding list; dynamically generating a herding and loading plan based on the priority herding list, combined with the pigs' pathogen carrier status and / or health risk level, according to the principle of prioritizing the merging of pigs with the same status; dynamically allocating target pens and generating herding paths and loading instructions based on the herding and loading plan, combined with the integrated pen layout and the comprehensive rating results; by integrating health monitoring and reproductive performance data to comprehensively rate and prioritize pigs, herding decisions no longer rely on a single indicator or human experience, and can accurately identify high-value breeding pigs and sick pigs that need to be isolated. In the herding and loading stage, the combination of the pigs' pathogen carrier status or health risk level and the principle of prioritizing the merging of pigs with the same status prevents the mixing of pigs with different health statuses, strengthening biosecurity control. Target pens are dynamically allocated based on the loading plan and pen layout, and transfer routes are generated to improve pen turnover efficiency and reduce pig stress and environmental control delays caused by chaotic transfers. By scientifically planning the transfer process, the risk of disease outbreaks and treatment costs are reduced, ensuring smooth connection between various breeding stages and improving pig survival rates and overall breeding efficiency.

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Example 1 This invention provides a method for planning and scheduling the transfer of pigs in an integrated pig farming system, applicable to such a system. (See also...) Figure 1 The flowchart shown in this embodiment of the invention provides a method for integrated pig farming and herding planning and scheduling. Figure 2 The diagram shown in this embodiment of the invention illustrates an integrated pig farming and herding method, which includes: Step S102: Obtain health monitoring data and reproductive performance data of the pigs to be transferred.

[0028] Specifically, the health monitoring data originates from key point recognition technology for pigs in high-density farming scenarios. Image acquisition devices deployed within the pigpens capture individual pig information in real time, and deep learning algorithms are used to locate and track key points (such as the base of the ears, spine, and limb joints) to analyze and identify multi-dimensional health indicators such as abnormal body temperature, surface damage, abnormal movement posture, and decreased feeding behavior. For example, when a pig exhibits lameness, the algorithm can identify abnormal movement posture through gait cycle analysis; if a pig stays away from the feeding area for an extended period and feeds significantly less frequently, it is considered to have decreased feeding behavior. Furthermore, the system also integrates disease detection results from daily inspection records (such as antigen detection data for swine fever and porcine reproductive and respiratory syndrome), forming a complete individual health record. Through the fusion of these multi-dimensional data, the system can track the health status of each pig in real time, providing a data foundation for subsequent precise grouping. This avoids the lag and subjectivity of traditional manual inspections, achieving automated and real-time health monitoring, significantly improving the early identification of sick and weak pigs, thereby reducing the risk of disease spread.

[0029] Furthermore, in some preferred embodiments of the present invention, the health monitoring data includes at least one of the following: abnormal body temperature, skin lesions, abnormal movement posture, decreased feeding behavior, and disease detection results.

[0030] Specifically, abnormal body temperature is detected using infrared thermometers and key point temperature inversion algorithms, enabling early warning of febrile diseases; skin lesions such as erythema, ulcers, or injuries are identified through image segmentation algorithms, suggesting possible fighting or skin diseases; abnormal movement postures are identified through gait analysis models, such as lameness, rigidity, or ataxia, which are associated with nervous system or limb diseases; decreased feeding behavior is assessed by monitoring feeding frequency and duration, indicating digestive system or systemic infections; and disease detection results are integrated with laboratory antigen / antibody detection data, such as for swine fever, porcine reproductive and respiratory syndrome (PRRS), and pseudorabies, as a basis for diagnosis. These multi-source data complement each other, constructing a comprehensive health profile covering clinical symptoms, behavioral abnormalities, and laboratory diagnoses. This allows the system to accurately identify subclinically infected individuals, promptly cull at-risk pigs before regrouping, and effectively prevent the transmission of pathogens to healthy populations.

[0031] Furthermore, in some preferred embodiments of the present invention, reproductive performance data include at least one of the following: number of live offspring, number of offspring with offspring, parity birth performance, lactation capacity, and genetic index.

[0032] Specifically, live piglet count refers to the number of live piglets born per litter, a core indicator of sow reproductive efficiency; litter size reflects the sow's postpartum care ability and piglet survival rate; parity performance comprehensively assesses the sow's farrowing stability and piglet uniformity across different parities; lactation ability is quantified using litter weight at 21 days of age, directly related to sow's milk production and maternal behavior; and genetic index, based on pedigree information and breeding values, predicts the reproductive performance potential of offspring. The system retrieves the above data from the historical production database and scores each sow across multiple dimensions. For example, multiparous sows with more than 14 live piglets in three consecutive litters are marked as high-fertility individuals, and gilts with the top 20% genetic index are designated as key breeding targets. By quantifying reproductive performance, the system can accurately identify high-quality breeding pigs and inefficient sows, providing a scientific basis for subsequent priority transfer and breeding optimization, and avoiding the waste of high-quality germplasm resources.

[0033] Step S104: Based on health monitoring data and reproductive performance data, each litter of pigs is comprehensively rated to generate a priority transfer ranking list.

[0034] Specifically, health monitoring data and reproductive performance data are mapped to a unified scoring system on a litter basis. The health dimension is graded and scored based on the severity of indicators such as abnormal body temperature and movement disorders. For example, a 1°C increase in body temperature deducts a corresponding number of points, and lameness lasting more than 3 days deducts more points. The reproductive dimension is scored based on indicators such as the number of live piglets and suckling ability. For example, each live piglet exceeding the litter average adds a corresponding number of points, and each litter weight exceeding the standard at 21 days of age adds a corresponding number of points. The two are weighted to obtain a comprehensive score, with the reproductive dimension weight dynamically adjusted according to pig type—higher weight for breeding sows and higher weight for commercial sows. Based on this score, each litter is initially ranked to ensure that pigs with high health and high reproductive capacity receive higher priority for regrouping, laying a scientific foundation for subsequent pen resource allocation. Transforming multidimensional heterogeneous data into comparable quantitative indicators avoids the bias of single-indicator decisions and improves the accuracy of regrouping decisions.

[0035] Furthermore, in some preferred embodiments of the present invention, the step of comprehensively rating each litter of pigs based on health monitoring data and reproductive performance data to generate a priority transfer ranking list includes: arranging all litters to be transferred in descending order by the number of live piglets, and then in descending order by the number of piglets with which they are being transferred; selecting healthy sows from the top-ranked litters in order of the target number of sows to be transferred, until the preset target number of sows is reached; selecting boars from the location of the last selected sow litter upwards in order of the target number of boars; and marking the litter as "selecting only sows," "selecting the entire litter," or "other" according to the selection situation, and assigning it a corresponding three-level rating of A, B, or C.

[0036] Specifically, sows are first sorted in descending order of live piglet count to ensure high-producing sows are prioritized. If the number of live piglets is the same, they are then sorted in descending order of the number of piglets they have with them, prioritizing sows with strong nursing abilities. Sows are selected sequentially from the highest-ranked litter until the target number is reached. Boars are selected by tracing back from the last selected sow's litter to ensure close blood ties or pen relationships between boars and selected sows, facilitating subsequent integration management. Based on the selection results, litters are categorized into three types: litters with only sows selected are marked "Sows Only" and assigned grade A; litters with both sows and boars selected are marked "Litter Selected" and assigned grade B; and litters that do not meet the selection criteria are marked "Other" and assigned grade C. By converting reproductive performance indicators into intuitive priority labels, high-fertility pigs are given priority for transfer to other groups, achieving a tilt of pen resources towards high-quality pig herds and effectively improving the utilization rate of breeding pigs and the reproductive performance of offspring.

[0037] Furthermore, the rating process includes exclusion rules for entire litters: litters with fewer than 12 live piglets in a single-parity farrowing house are excluded, as are litters with fewer than 14 live piglets in a multiparous house; litters containing spotted pigs (mixed coat colors) are also excluded. These rules are quantified based on practical production experience, directly filtering out litters with significantly low reproductive performance or genetic defects, preventing inefficient pigs from occupying valuable pen space and transportation resources, thereby improving overall breeding efficiency.

[0038] Step S106: Based on the priority transfer sorting list, combined with the pathogen carrier status and / or health risk level of the pigs, and following the principle of prioritizing the merging of pigs with the same status, dynamically generate a pens-merging and loading plan.

[0039] Specifically, the litters are first divided into lactation unit units after rating, maintaining the original priority order. Then, based on the pigs' pathogen carrier status (e.g., antigen test results for PRRS, swine fever, pseudorabies, etc.) or health risk level (e.g., whether they are in the incubation period or have been in contact with sick pigs), litters with the same status are merged, and litters with different statuses are strictly prohibited from being mixed. In terms of merging order, litters rated A ("select only sows") are merged first, and then merged in descending order of ranking, with the number per truck not exceeding a set threshold (e.g., 50 pigs). If there are not enough A-grade litters to fill one truck, they are supplemented from the B-grade "select whole litters" according to ranking, until one truck is full. The remaining litters (including C-grade and unselected litters) continue to be merged in order of priority to generate a complete truckload. This process also considers the feasibility of actual loading operations, such as the loading density of pigs per truck, transportation distance, vehicle turnover efficiency, etc., and dynamically adjusts the upper limit of the number of pigs per truck. By prioritizing the merging of pigs in the same condition, the transmission path of pathogens between different healthy groups is effectively blocked, and cross-infection is eliminated from the process. At the same time, prioritizing the merging of high-rated litters ensures the centralized management and efficient transfer of high-quality pigs, thereby improving the overall efficiency of herding.

[0040] Furthermore, in some preferred embodiments of the present invention, the steps of dynamically generating a pen-to-vehicle loading plan based on a priority transfer sorting list, combined with the pathogen carrier status and / or health risk level of the pigs, and following the principle of prioritizing the merging of pigs with the same status, include: splitting the graded litters into lactation pen units while maintaining priority order; merging litters with the same status according to the pathogen carrier status and / or health risk level of the pigs, prohibiting the mixing of litters with different statuses; prioritizing the merging of sow litters with a grade of A, merging them in descending order of ranking, with the number per vehicle not exceeding a set threshold; if there are not enough A-grade litters for one vehicle, supplementing them from the selected litters with a grade of B according to ranking; merging the remaining litters in order of priority to generate a complete vehicle load.

[0041] Specifically, the system first reads the layout information of each lactation unit from the database and groups the litters within the same unit according to their rating and priority. For example, for the five Grade A "sow-only" litters in Unit A, the system merges them into one group and calculates whether the total number of pigs exceeds the threshold of 50. If it does not exceed this threshold, it continues to transfer litters of the same status with higher ratings from Unit B until a truckload is full. During the merging process, the system monitors the area occupied by each pig in real time to ensure that the transport density standard (e.g., 0.4-0.5㎡ / pig) is met and to avoid overcrowding. For positive pens, the system prioritizes short-distance transport and designates dedicated vehicles and channels to prevent cross-contamination with negative pens, ensuring the orderliness and safety of the transfer process.

[0042] Furthermore, in some preferred embodiments of the present invention, the pathogen-carrying status includes: the result of PRRS antigen detection; according to the principle of preferential merging of the same status, the following applies: merging PRRS negative circles with PRRS negative circles, merging PRRS positive circles with PRRS positive circles, and prohibiting the mixing of PRRS negative circles and PRRS positive circles.

[0043] Specifically, porcine reproductive and respiratory syndrome (PRRS) is a major infectious disease in the swine industry, and its prevention and control are key aspects of herd management. After obtaining PRRS antigen test results, the system marks all litters to be transferred as negative or positive, strictly adhering to the principle of merging litters with similar status. For negative litters, they are prioritized for loading together with other negative litters. If the number of remaining negative litters is less than one truckload, the system will not merge them with positive litters, but will postpone the transfer or arrange for separate small vehicles to ensure the absolute safety of negative litters. For positive litters, the system centrally loads them onto trucks and transports them to dedicated positive isolation pens, implementing the highest level of biosecurity measures throughout the process (such as level 2 personnel protection and vehicle disinfection). A strict merging and isolation mechanism has been established for PRRS to prevent the spread of the disease due to herd transfer operations from the source. This is particularly suitable for farms under high pressure for PRRS prevention and control, significantly reducing the risk of infection throughout the farm.

[0044] Step S108: Based on the pen loading plan, combined with the integrated pen layout and comprehensive rating results, dynamically allocate target pens, and generate transfer routes and loading instructions.

[0045] Specifically, the pens within the integrated farrowing house are divided into Grade A pens and regular pens based on their ratings. For example, pens 1-6 are designated as Grade A pens by default, specifically for loading farrowing pens rated Grade A. When loading pigs, Grade A litters are prioritized for allocation to Grade A pens. If the number of Grade A litters exceeds the capacity of Grade A pens, the number of Grade A pens is expanded symmetrically (e.g., adding two corresponding pens each time) until the demand is met. The remaining pens are then used for Grade B litters. Simultaneously, passageway pens (such as pens 7 and 21) are reserved in the pen layout to ensure ventilation and disease prevention isolation. Within the same pen unit, secondary allocation is performed based on pathogen-carrying status: negative pens are loaded first, followed by positive pens, to avoid mixing. If the number of litters requiring regrouping exceeds the total number of pens, additional litters are added to each integrated house according to the principle of average allocation to ensure balanced load. For piglet pens, a strategy of leaving four empty pens in the middle of each row is adopted, and pigs are loaded sequentially from front to back according to the truckload to maintain uniform density within the pen. Finally, based on the allocation results, the system generates detailed transfer routes (such as the movement route from the source pen to the target pen) and loading instructions (including loading sequence, vehicle scheduling, and personnel arrangements), and sends them to the terminal equipment to guide on-site operations. This dynamic allocation mechanism fully utilizes the potential of pen space, avoids environmental control delays caused by chaotic transfers, and, through tiered and zoned management, provides suitable growth environments for pigs in different health states, further reducing stress and disease risks.

[0046] Furthermore, in some preferred embodiments of the present invention, the step of dynamically allocating target spaces includes: dividing the integrated housing into Grade A spaces and ordinary spaces, and preferentially allocating nests rated A to Grade A spaces; if the number of Grade A nests exceeds the capacity of Grade A spaces, then expanding the number of Grade A spaces according to the principle of symmetry; within the same housing unit, allocating spaces according to pathogen carrier status and / or health risk level; if the number of nests to be transferred exceeds the total number of spaces, then supplementing the number of nests to each integrated housing unit according to the principle of average allocation.

[0047] Specifically, during pen allocation, the system first reads the CAD layout diagram or digital pen model of the integrated pig farm, identifying the pen number, location, area, and environmental control configuration of each pen. Grade A pens are typically selected in areas close to the air inlet, with ample lighting and high temperature control precision, providing the optimal growth environment for high-quality pigs. When the number of Grade A litters exceeds the capacity of the Grade A pens, the system expands symmetrically: for example, by adding adjacent pens symmetrically on both sides of the existing Grade A pens, ensuring that the expanded area maintains a relatively concentrated layout, facilitating subsequent precise environmental control and feeding management. Within the same pig farm unit, the system divides the pig herd into zones based on their pathogen-carrying status (e.g., PRRS, swine fever), setting up empty pen isolation strips or physical barriers between negative and positive zones to prevent pathogen transmission via aerosols or personnel. If the number of litters requiring relocation exceeds the total number of pens, the system allocates additional litters proportionally to the remaining capacity of each integrated pig farm, avoiding overloading of individual units and affecting environmental control effectiveness. This precise matching of pen resources with pig herd needs achieves a dual improvement in space utilization efficiency and biosecurity levels.

[0048] Furthermore, in some preferred embodiments of the present invention, the method further includes: before the regrouping is executed, a regrouping coordination meeting is held according to the generated regrouping path and the pig loading execution instruction to clarify the personnel movement, disinfection process and isolation measures; during the regrouping process, suspected sick pigs are sorted in real time and guided to the isolation observation pen; after the regrouping is completed, the pigs' feed intake, daily weight gain and mortality rate are recorded and fed back to the system for optimizing subsequent scheduling strategies.

[0049] Specifically, before the transfer, the system automatically generates a coordination meeting agenda, organizing multiple departments such as biosafety, production management, and equipment maintenance to jointly confirm the boundaries between clean and contaminated areas, plan one-way personnel flow routes, and set up dedicated transfer channels and physical barriers to ensure that the transfer process does not overlap with other batches. The disinfection process is broken down into three stages: before, during, and after the transfer. Before the transfer, the channels and tools are thoroughly disinfected, and the transfer tools are soaked in potassium persulfate compound. During the transfer, vehicle tires and personnel shoe soles are sprayed with disinfectant in real time, and disinfection is carried out after each transfer. After the transfer, empty pens are flame-sterilized or fumigated and left to stand for more than 48 hours. The isolation measures include setting up isolation observation zones along the transfer route. On-site personnel, using sound and light guidance equipment, immediately sort suspected sick pigs exhibiting coughing, lameness, lethargy, or external injuries into the isolation area. Rapid pathogen detection procedures (such as PRRS PCR testing and classical swine fever antigen colloidal gold test strips) are initiated. Positive individuals are removed from the herd within 12 hours, and pigs that had contact with them in the same pen are placed under close observation. After the transfer is completed, the system automatically collects and records production data such as feed intake, daily weight gain, and mortality rate. This data is compared and analyzed with historical data to identify weaknesses in the process (such as high stress response on a particular route or a significant decrease in feed intake in a particular batch), thereby optimizing subsequent transfer strategies (such as adjusting the mixing size, modifying route planning, or increasing the frequency of disinfection at certain stages). Through this closed-loop management, biosecurity measures are rigidly implemented, emergency response speed is significantly improved, and the continuous accumulation of production data provides training samples for the algorithm's self-evolution, making the scheduling scheme increasingly optimal with use.

[0050] Furthermore, in some preferred embodiments of the present invention, the method further includes: pre-conditioning the environment and inspecting the equipment in the pig house before the transfer, including at least one of the following: water line disinfection, feed line detection, and temperature and humidity control; and using acidified drinking water and anti-stress intervention measures during the transfer process to reduce stress response in pigs.

[0051] Specifically, 24 hours before the pigs arrive, the system, in conjunction with environmental control equipment, pre-adjusts the environment of the target pens: water pipes are cleaned and soaked in food-grade disinfectant (such as potassium persulfate compound) to ensure no biofilm residue remains; samples are taken and tested to ensure the total bacterial count meets standards before use; feed line augers, sensors, and feeding devices are inspected and repaired, and mechanical failure risks are eliminated through no-load testing, calibrating feeding accuracy to within ±5%; the spray system and temperature and humidity controllers are calibrated, setting target parameters according to the pigs' age and season, and adjusting the temperature and humidity in the pens to suitable ranges in advance (e.g., 28-30℃ temperature and 60-70% humidity in suckling pens; 26-28℃ temperature and 60-65% humidity in nursery pens). Biosecurity supplies are prepared simultaneously, including disinfectants and equipment (flame sterilizers, electric sprayers), isolation protective clothing, and specialized transport tools (such as detachable transport vehicles and special baffles). During the regrouping process, as pigs move through a dedicated passage, the system automatically activates the acidified drinking water device, adjusting the pH of the water to 3.5-4.0 to inhibit the growth of intestinal pathogens. Simultaneously, an electrolyte and vitamin C complex is added to the drinking water to alleviate stress caused by transportation and regrouping. On-site personnel use sound and light guidance equipment to guide the pigs forward in an orderly manner, avoiding rough handling that could cause injury. Upon reaching the target pen, ample acidified drinking water and palatable starter feed are immediately provided to help the pigs quickly adapt to the new environment. Through this dual approach of environmental pre-regulation and anti-stress intervention, the pigs' physiological fluctuations are minimized, their immunity remains stable, and the risk of secondary diseases induced by regrouping stress (such as swine respiratory disease syndrome and post-weaning diarrhea) is significantly reduced, laying a solid foundation for their subsequent healthy growth.

[0052] This invention provides a method for planning and scheduling pig herding in an integrated pig farm, comprising: acquiring health monitoring data and reproductive performance data of pigs to be herded; comprehensively rating each litter based on the health monitoring data and reproductive performance data to generate a priority herding list; dynamically generating a herding and loading plan based on the priority herding list, combined with the pigs' pathogen carrier status and / or health risk level, according to the principle of prioritizing the merging of pigs with the same status; dynamically allocating target pens and generating herding paths and loading instructions based on the herding and loading plan, combined with the integrated pen layout and the results of the comprehensive rating; by integrating health monitoring and reproductive performance data to comprehensively rate and prioritize pigs, the herding decision no longer relies on a single indicator or human experience, and can accurately identify high-value breeding pigs and sick pigs that need to be isolated. In the herding and loading stage, the method combines the pigs' pathogen carrier status or health risk level, following the principle of prioritizing the merging of pigs with the same status, thus preventing the mixing of pigs with different health statuses and strengthening biosecurity control. Target pens are dynamically allocated based on the loading plan and pen layout, and transfer routes are generated to improve pen turnover efficiency and reduce pig stress and environmental control delays caused by chaotic transfers. By scientifically planning the transfer process, the risk of disease outbreaks and treatment costs are reduced, ensuring smooth connection between various breeding stages and improving pig survival rates and overall breeding efficiency.
