Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, specifically relating to an automatic growth performance recording device for individual experimental pigs. Background Technology

[0002] In animal husbandry and animal science research, accurate recording of the growth performance of individual experimental animals is a crucial foundation for evaluating their growth status and developing scientific feeding and management programs. However, currently widely used methods for measuring the growth performance of experimental animals have many shortcomings, especially in experiments with experimental pigs, where these shortcomings are particularly prominent.

[0003] Traditional experimental data collection methods mainly rely on manual operation and periodic collection. For example, researchers need to periodically drive experimental pigs to a weighing platform at a fixed location to measure their weight and obtain periodic weight data. However, this method has several obvious drawbacks: 1. High labor intensity and low efficiency: During the experiment, manual driving and weighing operations require a lot of time and energy, especially for larger pigs. The process of moving and weighing is not only laborious but also increases the possibility of injury to researchers.

[0004] 2. Long data recording intervals and insufficient dynamic monitoring: Data obtained by traditional methods have obvious time intervals, making it impossible to achieve real-time dynamic monitoring. This results in lag in experimental data and makes it impossible to achieve comprehensive and continuous monitoring of the growth status of experimental pigs.

[0005] 3. High stress on experimental pigs: Driving experimental pigs to a fixed location for weighing often interferes with their normal behavior and physiological state, inducing a significant stress response. This stress not only affects the growth and health of the experimental pigs but may also lead to distorted experimental results.

[0006] 4. Errors are prone to occur during the recording process: Manual recording is subjective, and data is easily affected by human negligence or errors, resulting in poor accuracy and consistency of experimental data.

[0007] With the continuous advancement of animal science research and breeding technology, the demand for monitoring the growth performance of laboratory pigs has shifted from periodic data collection to real-time, comprehensive dynamic recording. This not only more accurately reflects the growth trends of laboratory animals but also provides researchers with more scientific analytical basis. Meanwhile, under the trend of precision farming, reducing stress on laboratory animals, lowering labor costs, and improving the automation level of data collection have become important research directions.

[0008] Limitations of existing technologies: While some animal growth monitoring devices exist on the market, most are designed for group rearing scenarios and cannot meet the needs of individual experimental pigs. For example, group rearing devices often collect data through zoned monitoring, failing to accurately record detailed growth data for individual pigs. Existing devices for individual pigs are relatively limited in function, only able to monitor a single indicator (such as weight), and cannot comprehensively record multiple growth performance indicators such as feed intake, water consumption, and fecal and urinary output. Furthermore, these devices typically have low levels of automation and lack real-time data uploading, storage, and analysis capabilities, forcing researchers to still rely heavily on manual intervention and subsequent data processing. Summary of the Invention

[0009] This invention addresses the aforementioned problems by providing an easy-to-use automatic growth performance recording device for real-time collection of various data from individual pigs, particularly suitable for use in the breeding of experimental pigs or breeding pigs.

[0010] To achieve the above-mentioned objectives of this utility model, the present utility model adopts the following technical solution: the present utility model includes a bed box, characterized in that: a feeding device and a watering device are provided at one end of the upper part of the bed box; a first weighing device is provided below the feeding device, and a second weighing device is provided below the watering device; a load-bearing plate is provided in the middle of the bed box, and a main weighing device is provided below the load-bearing plate; a feces and urine separation device is provided inside the other end of the bed box, and a solid collection box and a liquid collection box are provided inside the feces and urine separation device; a third weighing device is provided at the bottom of the solid collection box, and a fourth weighing device is provided at the bottom of the liquid collection box; fences are provided on both sides of the upper part of the bed box, and at the end opposite to the feeding device and the watering device; the distance between the two fences is 0.3 to 0.6 m.

[0011] As a preferred embodiment of this utility model, the fecal-urine separation device includes a box body, with support bars for a solid collection box and a liquid collection box arranged on both sides of the box body; the third and fourth weighing devices are arranged on the support bars; and the side of the bed box is provided with an installation groove that cooperates with the box body.

[0012] Furthermore, the box is provided with a handle for taking the box out and putting it in.

[0013] Furthermore, the side of the box is provided with a side door for taking out and placing the solid collection box and the liquid collection box.

[0014] Furthermore, the solid collection box is provided with a mesh cover at the top and a mesh bottom at the bottom, with the mesh openings of the mesh cover being larger than those of the mesh bottom; the liquid collection box is a trough-shaped body located below the solid collection box.

[0015] Furthermore, the height of the upper surface of the mesh cover is lower than the height of the load-bearing plate.

[0016] As another preferred embodiment of this utility model, the load-bearing plate includes a bed board, which is composed of a frame and multiple strip boards with gaps between them; multiple support columns are provided under the bed board, and the support columns are connected to a support plate; the main weighing device is located under the support plate.

[0017] Furthermore, the upper surface of the support plate is provided with an inclined drain trough, and the bed box is provided with a drain outlet corresponding to the inclined direction of the drain trough.

[0018] As a third preferred embodiment of this utility model, the bed box is provided with end railings at both ends above the bed box, and side railings are provided on both sides above the bed box. The two end railings are fixed to the bed box, and multiple slots that cooperate with the side railings are arranged on the two end railings. The distance between the two side railings can be adjusted by installing the side railings in slots at different positions.

[0019] As a fourth preferred embodiment of the present invention, the feeding device includes a feeding trough and a feed container connected at the bottom; a top cover is provided on the feed container; the water feeding device includes a water feeding trough and a water bucket mounting slot connected at the bottom, and a water bucket mounting opening is provided on the top of the water bucket mounting slot.

[0020] The beneficial effects of this invention are as follows: 1. High degree of automation, saving manpower and time: This invention integrates multiple weighing modules, which can simultaneously collect data on pig weight, feed intake, water intake, fecal volume, and urine volume; achieving fully automatic real-time monitoring of the growth performance of experimental pigs. Data such as weight, feed intake, water intake, fecal volume, and urine volume can be collected without manual intervention, significantly reducing the labor intensity of experimental operators, saving time costs for data collection, and improving experimental efficiency.

[0021] 2. Real-time dynamic monitoring for more comprehensive data: Traditional phased data collection methods cannot capture the subtle changes in the dynamic growth of pigs during experiments. This invention can continuously collect data on various growth performance indicators in the natural state of experimental pigs, providing researchers with high-frequency, dynamic, real-time monitoring results, showing the complete trend of pig growth, and making the experimental results more scientific and reliable.

[0022] 3. Reduced stress and improved animal welfare: Data such as the weight of the experimental pigs were automatically collected by the equipment, eliminating the need to drive the pigs to the weighing platform or intervene manually during data collection, thus avoiding stress caused by operational interference. This not only protected the health and normal growth of the pigs but also ensured the scientific validity of the subsequent data and the accuracy of the experimental results.

[0023] 4. Fecal-urine separation structure for more accurate data: The device features a built-in fecal-urine separation structure that collects and weighs feces and urine separately, effectively avoiding data contamination and interference. This structure makes the measurement of fecal and urine volumes more accurate, providing important reference data for studying digestion and metabolism during the feeding process.

[0024] 5. Highly adaptable and meets diverse experimental needs: Through the adjustment of the fence, experiments can be conducted on pigs of different sizes and breeds. Attached Figure Description

Detailed Implementation

[0031] This utility model includes a bed box 7, characterized in that: a feeding device 22 and a watering device 23 are provided at one upper end of the bed box 7; a first weighing device 27 is provided below the feeding device 22; and a second weighing device 28 is provided below the watering device 23; a load-bearing plate 2 is provided in the middle of the bed box 7; and a main weighing device 5 is provided below the load-bearing plate 2; a feces and urine separation device 16 is provided inside the other end of the bed box 7; a solid collection box 14 and a liquid collection box 11 are provided inside the feces and urine separation device 16; a third weighing device 12 is provided at the bottom of the solid collection box 14; and a fourth weighing device 10 is provided at the bottom of the liquid collection box 11; fences are provided on both sides of the upper part of the bed box 7, and at the end opposite to the feeding device 22 and the watering device; the distance between the fences 1 on both sides is 0.3 to 0.6 m.

[0032] This invention, through the inclusion of a feeding device 22, a watering device 23, a main weighing device 5, and a feces-urine separation device 16, achieves automated collection of multi-dimensional data on feed intake, water intake, weight, feces volume, and urine volume of experimental pigs. The feces-urine separation device 16 effectively avoids solid-liquid mixing, ensuring data accuracy. The fence design not only prevents pigs from escaping but also prevents them from turning around, guaranteeing the reliability of feces-urine data collection.

[0033] The fecal-urine separation device 16 includes a housing 17, with support bars 9 for a solid collection box 14 and a liquid collection box 11 arranged on both sides inside the housing 17; the third weighing device 12 and the fourth weighing device 10 are arranged on the support bars 9; the side of the bed box 7 is provided with an installation groove that cooperates with the housing 17.

[0034] The feces and urine separation device 16 secures the solid collection box 14 and the liquid collection box 11 to the support strips 9 inside the housing 17, facilitating stable installation of the weighing device and data acquisition. The mounting groove design on the side of the bed box 7 allows for flexible installation and removal of the feces and urine separation device 16, facilitating daily cleaning and maintenance.

[0035] The box 17 is provided with a handle 19 for taking the box 17 out of the box.

[0036] The handle 19 on the housing 17 improves the ease of moving and taking out the fecal-urine separation device 16, making the cleaning process more efficient and reducing the labor intensity of the experimental personnel.

[0037] The side of the box 17 is provided with a side door for taking out and putting in the solid collection box 14 and the liquid collection box 11.

[0038] By incorporating a side door, the method of accessing and placing the solid collection tank 14 and the liquid collection tank 11 has been further optimized, ensuring a more hygienic and efficient cleaning and replacement process.

[0039] The solid collection box 14 is provided with a mesh cover 15 at the upper end and a mesh bottom 13 at the lower end. The mesh openings of the mesh cover 15 are larger than the mesh openings of the mesh bottom 13. The liquid collection box 11 is a trough-shaped body located below the solid collection box 14.

[0040] The mesh cover 15 and mesh bottom 13 of the solid collection box 14 are designed with different sized mesh openings to achieve efficient separation of feces and urine. The double-layer mesh structure can prevent excessive feces residue on the top layer and maintain the living environment for pigs; while liquids go directly into the liquid collection box 11 below. The trough-shaped liquid collection box 11 facilitates the collection and weighing of urine.

[0041] The height of the upper surface of the mesh cover 15 is lower than the height of the load-bearing plate 2.

[0042] The height of the mesh cover 15 is lower than that of the load-bearing plate 2, ensuring the stability of the pigs' activities inside the device and effectively guiding excrement into the collection device, thereby improving the efficiency of manure and urine separation.

[0043] The load-bearing plate 2 includes a bed board, which is composed of a frame 21 and multiple strip plates 20, with gaps between the strip plates 20; multiple support columns 6 are provided below the bed board, and the support columns 6 are connected to a support plate 3; the main weighing device 5 is located below the support plate 3.

[0044] The frame 21 and strip plate 20 structure of the load-bearing plate 2 not only enhance the load-bearing capacity, but also reduce the possibility of excrement accumulating on the bed board through the gap design. It also facilitates cleaning of the pigs and the bed box 7. Together with the support column 6 and support plate 3, the overall structure ensures the comfort and stability of the pigs in the device.

[0045] An inclined drain trough 4 is provided on the upper surface of the support plate 3, and a drain outlet 8 is provided on the bed box 7 in the direction of inclination of the drain trough 4.

[0046] The drainage trough 4 on the support plate 3 is designed with a reasonable inclination to guide the liquid flowing from the load-bearing plate 2 into the bed box 7 (mainly the liquid generated when cleaning pigs and the load-bearing plate 2) to the drainage outlet 8 for easy centralized cleaning and to keep the inside of the device clean and tidy.

[0047] As a third preferred embodiment of this utility model, the bed box 7 is provided with end railings 18 at both ends above the bed box 7, and side railings 1 are provided on both sides above the bed box 7. The two end railings 18 are fixed to the bed box 7, and multiple slots that cooperate with the side railings 1 are arranged on the two end railings 18. The distance between the two side railings 1 is adjusted by installing the side railings 1 in slots at different positions.

[0048] By designing multiple slots on the end fence 18, the position of the side fence 1 can be flexibly adjusted to accommodate experimental pigs of different sizes, increasing the applicability of the device and improving the safety and comfort of the experimental pigs' activity area.

[0049] As a fourth preferred embodiment of the present invention, the feeding device 22 includes a feeding trough 26 and a feed container 25 connected at the bottom; a top cover 24 is provided above the feed container 25; the water feeding device 23 includes a water feeding trough 29 and a water bucket mounting slot 30 connected at the bottom, and a water bucket mounting opening is provided above the water bucket mounting slot 30.

[0050] The design of the feeding device 22 and the watering device 23 enables automatic supply of feed and water, and the interconnected structure of the feeding trough 26 and the water trough facilitates cleaning and replenishment.

[0051] The main weighing device 5, the first weighing device 27, the second weighing device 28, the third weighing device 12, and the fourth weighing device 10 are all connected to the data acquisition, processing, and display system via lines.

[0052] The data acquisition and processing systems can be installed inside the bed box, in the equipment box located below the main weighing device.

[0053] Collecting pig feces and urine separately is a technical challenge. Based on the physiological characteristics of pigs, the distance between the two fences 1 is designed to be 0.3 to 0.6 meters. Pigs cannot turn around inside the fence and can only stand or lie on their side. At the same time, taking advantage of the pigs' habit of not resting near excrement, the pigs defecate only at one end of the feces and urine separation device 16. After testing, the feces and urine collection data are accurate.

[0054] The feeding device 22 and watering device 23 of this utility model are existing products that can be purchased on the market.

[0055] When using this invention, it can also be combined with environmental humidity and temperature data collection to increase the data dimensions, making the data collection richer and more comprehensive, and the experimental results more accurate and reliable.

[0056] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
