Description

Technical Field

[0001] This invention belongs to the field of supplementary feeding for pig farming, specifically a method for supplementary feeding of pigs in forest-based free-range areas. Background Technology

[0002] Understory farming can maximize land efficiency, boosting agricultural productivity, increasing farmers' income, and promoting forestry prosperity. Hainan, a major forestry province with a unique ecological environment, possesses enormous advantages and potential for developing understory farming. In recent years, Hainan's active development and promotion of green development has spurred and benefited rural revitalization. Hainan's understory farming refers to a method of raising Wuzhishan pigs in forest environments, such as coconut groves, areca nut groves, rubber plantations, and fruit orchards, combining stall feeding with free-range grazing. This method effectively mitigates pollution from livestock farming, alleviates land scarcity, and produces naturally high-quality Wuzhishan pigs, making it popular among large-scale farmers and consumers.

[0003] Wuzhishan pig is a famous small pig breed in my country and one of the national geographical indication agricultural products. It originated in the Wuzhishan area of ​​central Hainan Province, and since the 1960s, it has been mainly concentrated in Baoting, Wuzhishan, Qiongzhong, and Sanya. In 2000, it was included in the "National List of Protected Livestock and Poultry Breeds". Wuzhishan pigs are characterized by their small size, early maturity, strong reproductive performance, tolerance to roughage, strong disease resistance, tolerance to inbreeding, stable genetics, thick skin with little fat, and delicious meat. It combines the advantages of domestic pigs and wild boars, retaining the high lean meat percentage, delicious meat, and high nutritional value of wild boars, while overcoming the disadvantages of wild boars such as seasonal estrus and difficulty in raising them. It also has the advantages of strong disease resistance, wide adaptability, low feeding costs, and high economic benefits. Currently, Wuzhishan pigs reach a slaughter weight of 40-50 kg, with a feeding cycle of 10-12 months. Prices are less affected by market fluctuations. There are several feeding methods, including free-range, stall feeding with restricted feeding, and free-range with supplementary feeding. Free-range pigs raised with supplementary feeding produce pork of higher quality and more flavorful color, making them suitable for the high-end market and offering considerable economic benefits. Since free-range Wuzhishan pigs require a reasonable amount of energy and protein for growth, scientifically supplementing their diet can significantly improve the industrialization and market competitiveness of Wuzhishan pigs.

[0004] For example, Chinese Patent Publication No. CN 105010155 A discloses a supplementary feeding area and method for free-range pig farming under forest cover. Free-range pig farming is a newly emerging low-carbon and environmentally friendly farming method that has gained popularity in recent years. Due to differences in pig breeds and forest structure, farmers need to consider various factors such as forest land selection, the breed and weight of free-range pigs, grazing procedures, and management when raising pigs under forest cover. Otherwise, it will not only pollute the environment and waste resources but also cause significant economic losses. This invention comprises a supplementary feeding area, a control area, and an isolation area. A feed delivery area is located on one side of the supplementary feeding area, and a drinking water area is located on the opposite side. The control area includes an entrance, a movable baffle, a pig exit platform, and an exit. The isolation area includes an entrance and an exit. The supplementary feeding area has an entrance.

[0005] However, when supplementing free-range pigs with the above-mentioned methods, pigs at different growth stages are fed in the same supplementary feeding area. Since the energy required for supplementing free-range pigs at different growth stages is different, the types of supplementary feed also need to be different. The above-mentioned methods are not convenient for supplementing free-range pigs at different growth stages separately. Therefore, it is necessary to propose a method for supplementing free-range pigs in forest-based supplementary feeding areas. By dividing the supplementary feeding area, it is possible to adapt to supplementing free-range pigs at different growth stages, so as to promote the growth of free-range pigs at different growth stages. Summary of the Invention

[0006] The purpose of this invention is to propose a method for supplementing the feeding of free-range pigs in forest areas. By dividing the feeding area, it is possible to adapt to the supplementing of feeding for free-range pigs at different growth stages, so as to promote the growth of free-range pigs at different growth stages.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A method for supplementary feeding of pigs in a forest-based free-range feeding area, comprising the following steps:

[0008] Step 1: Construct the supplementary feeding area; the supplementary feeding area includes an adult pig area and a piglet area;

[0009] Step Two: Fix Supplementary Feeding Time and Establish Commands; Select fixed times for supplementary feeding and establish unified commands to create conditioned reflexes in free-range pigs and help them adapt to free-range management;

[0010] Step 3: Queuing and Categorized Feeding; Free-range pigs wait at the entrance of the feeding area. To prevent overcrowding at the entrance and to ensure that adult pigs enter the adult pig area and piglets enter the piglet area, one type of pig is herded. The free-range pigs about to enter the feeding area are photographed by a camera to identify their size and guide the adult pigs and piglets to enter the adult pig area and piglet area respectively for feeding.

[0011] Step 4, surface skin cleaning; while the free-range pigs are waiting at the entrance of the supplementary feeding area, clean the surface skin of the free-range pigs to reduce dirt on their surface.

[0012] Furthermore, the weight requirement for free-range piglets is: weight of 10kg or more.

[0013] Furthermore, the supplementary feeding area is divided into an adult pig area and a piglet area by partition walls; each adult pig area and piglet area is equipped with several feeding troughs; the supplementary feeding area has symmetrical entrance areas, which are connected to both the adult pig area and the piglet area; each adult pig area and piglet area has an exit area.

[0014] Furthermore, each entrance area has an entrance passage in the middle, which connects to the adult pig area and the piglet area; the entrance passage is wide enough for one adult pig or two piglets to pass through; a control area is set up in the entrance area, which is equipped with a controller and a power supply; several metal connectors are installed on one side wall of the entrance passage, and the metal connectors are electrically connected to the power supply through connecting wires.

[0015] Furthermore, a motor is installed inside the bottom wall of the entrance channel. The motor is electrically connected to the controller. The output shaft of the motor is coaxially fixedly connected to a rotating shaft. Several connecting rods are fixedly connected to the rotating shaft. The connecting rods at the same height form a cross shape. A camera is installed on the top of the rotating shaft. The camera is electrically connected to the controller.

[0016] Furthermore, several rollers are rotatably fitted on the side wall of the inlet channel away from the metal joint.

[0017] Furthermore, an electric fence is installed at the exit area, and the electric fence is electrically connected to the controller.

[0018] Furthermore, radio frequency tags are fixed to the ears of all free-range pigs.

[0019] Beneficial effects:

[0020] This invention identifies the body shape of free-range pigs about to enter the supplementary feeding area. When the identification information indicates an adult pig, the adult pig is guided to the adult pig area; when the identification information indicates a piglet, the piglet is guided to the piglet area. This division of the supplementary feeding area accommodates pigs at different growth stages, promoting their growth. To prevent overcrowding at the entrance of the supplementary feeding area and ensure that adult pigs enter the adult pig area and piglets enter the piglet area, the pigs are driven by an electric current. After being driven, the pigs approach a side wall equipped with rollers, which clean the dirt on their skin to a certain extent, preventing them from bringing large amounts of dirt into the supplementary feeding area. During supplementary feeding, music can be played, which can regulate the endocrine system of Wuzhishan pigs, activate immune factors, stabilize their emotions, increase appetite, and promote growth.

[0026] The following detailed description illustrates the specific implementation method:

[0027] The reference numerals in the accompanying drawings include: adult pig area 101, piglet area 102, feed trough 2, partition wall 3, entrance area 4, entrance channel 401, rotating shaft 402, connecting rod 403, camera 404, roller 405, metal joint 406, control area 5, and exit area 6.

[0028] Example 1

[0029] The basic implementation examples are as follows: Figure 1-5 As shown:

[0030] A method for supplementing feeding in a forest-based free-range pig feeding area includes the following steps:

[0031] Step 1: Construct the supplementary feeding area; the supplementary feeding area includes adult pig area 101 and piglet area 102;

[0032] Step Two: Fix Supplementary Feeding Time and Establish Commands; Select fixed times for supplementary feeding and establish unified commands to create conditioned reflexes in free-range pigs and help them adapt to free-range management;

[0033] Step 3: Queuing and Categorized Feeding; Free-range pigs wait at the entrance of the feeding area. To prevent overcrowding at the entrance and to ensure that adult pigs enter adult pig area 101 and piglets enter piglet area 102, one type of pig is driven. Camera 404 captures images of the free-range pigs about to enter the feeding area, identifies their body size, and guides the adult pigs and piglets to enter adult pig area 101 and piglet area 102 respectively for feeding.

[0034] Step 4, surface skin cleaning; while the free-range pigs are waiting at the entrance of the supplementary feeding area, clean the surface skin of the free-range pigs to reduce dirt on their surface.

[0035] The weight requirement for free-range piglets is: 10kg or more.

[0036] like Figure 2 As shown, the supplementary feeding area is equipped with a partition wall 3, which divides the supplementary feeding area into an adult pig area 101 and a piglet area 102. Each adult pig area 101 and piglet area 102 is equipped with several feeding troughs 2. The supplementary feeding area is symmetrically equipped with entrance areas 4, which are connected to both adult pig area 101 and piglet area 102. Each adult pig area 101 and piglet area 102 is equipped with an exit area 6.

[0037] Each entrance area 4 has an entrance passage 401 in the middle, which connects to the adult pig area 101 and the piglet area 102. The width of each entrance passage 401 is sufficient for one adult pig or two piglets to pass through. A control area 5 is located within entrance area 4, containing a controller and power supply. The preferred controller model is SPC-STW-S0402CTR. Several metal connectors 406 are installed on one side wall of each entrance passage 401. Figure 5 As shown, metal connector 406 is electrically connected to the power supply.

[0038] A motor (not shown in the figure) is installed inside the bottom wall of the entrance channel 401. The preferred model of the motor is 5RK60GN-CF. The motor is electrically connected to the controller. The output shaft of the motor is coaxially fixed to a rotating shaft 402 by bolts. Several connecting rods 403 are fixedly connected to the rotating shaft 402 by bolts. The connecting rods 403 at the same height form a cross shape. A camera 404 is installed on the top of the rotating shaft 402. The camera 404 is electrically connected to the controller.

[0039] Several rollers 405 are rotatably fitted on the side wall of the entrance channel 401 away from the metal joint 406.

[0040] The specific implementation process is as follows:

[0041] The first step is to construct the supplementary feeding area.

[0042] The supplementary feeding area is divided into a pig area 101 and a piglet area 102. In this embodiment, piglets refer to those aged 105 to 120 days and weighing 10 to 20 kg. Since this stage is a critical developmental stage in the entire pig farming process and has an important impact on subsequent growth and reproduction, the feed given to piglets at this stage is different from that given to adult pigs. Therefore, this invention divides the supplementary feeding area to adapt to the supplementary feeding of free-range pigs at different growth stages, so as to promote the growth of free-range pigs at different growth stages.

[0043] The second step is to fix the supplemental feeding time and establish a password.

[0044] By choosing fixed times for supplementary feeding and establishing unified commands, free-range pigs can develop conditioned reflexes and adapt to free-range management.

[0045] The third step involves queuing for entry and categorizing for supplemental feeding.

[0046] By using a verbal command to induce a conditioned reflex in the free-range pigs, they converge towards the entrance channel 401. The metal connector 406 is pre-connected to the power supply via a wire. Since the entrance channel 401 is only wide enough for one adult pig or two piglets to pass through, when the pigs crowd at the entrance channel 401, their skin comes into contact with the metal connector 406 on the side wall of the entrance channel 401. The pigs feel a stinging sensation under the influence of the electric current and move away from the side wall of the entrance channel 401 where the metal connector 406 is located, thus driving the pigs to one side and reducing crowding to some extent. In this embodiment, the current at the metal connector 406 is 0.5–0.8 mA, which is within a safe range and will not damage the skin of the free-range pigs.

[0047] Camera 404 captures images of free-range pigs about to enter the supplementary feeding area. The camera 404 transmits the image information to the controller, which identifies the pigs' body size. When the identified pig is an adult, it... Figure 2 For example, regarding the lower rotating shaft 402: When an adult pig stands between two connecting rods 403, the motor drives the rotating shaft 402 to rotate towards the adult pig area 101, that is, the motor drives the rotating shaft 402 to rotate clockwise. The connecting rods 403 on the rotating shaft 402 guide the adult pig, and the adult pig moves to the adult pig area 101 under the push of the connecting rods 403. When the identification information is a piglet, the piglet stands between the two connecting rods 403, and the motor drives the rotating shaft 402 to rotate towards the piglet area 102, that is, the motor drives the rotating shaft 402 to rotate counterclockwise. The connecting rods 403 on the rotating shaft 402 guide the piglet, and the piglet moves to the piglet area 102 under the push of the connecting rods 403. This allows the adult pig and the piglet to enter the adult pig area 101 and the piglet area 102 respectively for supplementary feeding. When two piglets stand between the two connecting rods 403, the connecting rods 403 guide both piglets simultaneously, increasing the guidance efficiency.

[0048] Step 4: Cleaning the surface skin

[0049] When a free-range pig is electrically stimulated and moves away from the side wall of the entrance channel 401 where the metal connector 406 is located, the pig moves towards the side wall of the entrance channel 401 where the roller 405 is located. When the pig comes into contact with the roller 405, the roller 405 can clean the dirt on the pig's skin to a certain extent, thus preventing the pig from bringing a large amount of dirt into the supplementary feeding area.

[0050] When supplementing feed, music can be played. Playing music can help regulate the endocrine system of Wuzhishan pigs, activate immune factors, stabilize their emotions, increase their appetite, and promote growth.

[0051] Example 2

[0052] The difference from the above embodiment is that electric fences are installed at 6 locations in the exit area, and the electric fences are electrically connected to the controller.

[0053] The specific implementation process is as follows: After the supplementary feeding of the free-range pigs is completed, the electric fence can be opened through the controller, and the free-range pigs can return to the forest through exit area 6 to continue grazing.

[0054] Example 3

[0055] The difference from the above embodiments is that the free-range pigs all have radio frequency cards fixed on their ears.

[0056] The specific implementation process is as follows: Radio frequency identification (RFID) technology is used to read and write RFID cards to identify free-range pigs, which facilitates free-range management.
