Description

Technical Field

[0001] This utility model relates to the field of breeding pig technology, and in particular to an auxiliary positioning device for boars used to detect estrus in sows. Background Technology

[0002] In the pig farming industry, sows are the foundation of pig production. In order to maintain good economic benefits and the reproductive performance of sows, it is necessary to continuously replenish sows and establish a replacement sow breeding program. This involves culling sows that are slow to come into heat, old and weak, have poor lactation capacity, or have reproductive problems, while selecting more replacement sows from a smaller replacement sow herd and effectively stimulating their sexual maturity. This can reduce the cost of breeding pig farms. Efficient management of replacement sows can improve the utilization rate of pig houses, manpower, and qualified replacement sows.

[0003] One of the most important factors in stimulating estrus in gilts is boar contact. The traditional method for checking estrus in gilts is to drive the gilts into the gestation pen, set up a boar contact area on the side where the gilts' heads are facing, drive the boars into the contact area so that each boar is paired with two to three gilts, and then monitor and record the estrus status of the gilts from the other side.

[0004] However, the movement of the testing boars is not under human control. When checking for estrus, multiple staff members need to work together to use barriers to restrict the boars and ensure that each testing boar corresponds to two to three gilts. This greatly increases the number of staff required, is time-consuming and labor-intensive, and reduces the efficiency of checking for estrus in gilts. Utility Model Content

[0005] To improve the efficiency of estrus detection in sows, this utility model provides an auxiliary positioning device for estrus detection using a boar.

[0006] The auxiliary positioning device for estrus detection in sows provided in this application adopts the following technical solution:

[0007] A boar positioning device for estrus detection in sows includes a sow confinement pen and an auxiliary surface. The sow confinement pen is used to confine the sow. The front end of the sow confinement pen has a front door, and the rear end of the sow confinement pen has a tail door. The front door faces the auxiliary surface and forms a confinement channel between the front door and the auxiliary surface for the boar to pass through. The confinement channel is provided with multiple positioning components for positioning the boar.

[0008] By adopting the above technical solution, sows are driven into the sow gestation pen with their heads facing the front door. After closing the front and rear doors, boars for estrus testing are driven into the gestation channel. Each boar corresponds to 2-3 sows. The gestation channel is blocked by multiple positioning components, with two adjacent positioning components positioning one boar. Thus, during estrus testing, there is no need for staff to hold barriers to gestate the sows. Staff only need to observe the sows' estrus status at the rear door, reducing labor costs and improving the efficiency of estrus detection.

[0009] Optionally, the positioning component includes:

[0010] A positioning plate is disposed on an auxiliary surface and extends vertically. The positioning plate has a vertically extending first groove that penetrates the top surface of the positioning plate and the side facing the front door.

[0011] A positioning block is provided at the front end of the sow gestation crate and is positioned opposite to the positioning plate. The positioning block has a vertically extending second groove, which is positioned opposite to the first groove.

[0012] A limiting plate is vertically inserted into a first groove and a second groove, and a limiting space is formed between two adjacent limiting plates to limit the boar.

[0013] By adopting the above technical solution, at the end of the estrus limiting channel, one limiting plate is first inserted into the first and second grooves to block the end of the limiting channel. Then, the boar is driven into the limiting channel. According to the number of sows corresponding to each boar, the next limiting plate is inserted between the sow limiting pen and the auxiliary surface at a suitable location. This process is repeated to limit the estrus of each boar. After the plates are inserted, the staff can leave to the tail gate to observe the sows. After the estrus check is completed, the limiting plates are moved out of the first and second grooves, and the boars can then be driven back to the breeding area. This improves the convenience of limiting boars when checking sows for estrus, thereby increasing the efficiency of estrus checks.

[0014] Optionally, the front end of the sow gestation crate is further provided with a gestation block. The gestation block is located above the positioning block and is positioned opposite to the positioning plate. The gestation block has a vertically extending third groove. The third groove penetrates the upper and lower surfaces of the gestation block and the side of the gestation block facing the positioning plate and communicates with the second groove. The gestation plate is vertically inserted into the first groove, the third groove and the second groove.

[0015] By adopting the above technical solution, the first groove of the positioning plate limits the side of the limiting plate facing the auxiliary surface, and the third groove of the limiting block and the second groove of the positioning block cooperate to limit the side of the limiting plate facing the front door, thereby improving the stability of the limiting plate insertion.

[0016] Optionally, the limiting plate has a handle at its top.

[0017] By adopting the above technical solution, the handle increases the convenience of inserting and removing the limiting plate.

[0018] Optionally, the auxiliary surface is provided with multiple storage hooks, and the limiting plate is hung on the storage hooks by a handle.

[0019] By adopting the above technical solution, unused limit plates can be hung on storage hooks via handles, which improves the convenience of storing limit plates.

[0020] Optionally, the front door is provided with a rotatable limit door, which rotates toward the positioning plate, and the positioning plate has a limiting component for limiting the limit door.

[0021] By adopting the above technical solution, when boar positioning is required without using a limiting plate, the limiting gate is rotated to the positioning plate, and the limiting component limits the limiting gate. If the limiting plate is damaged and cannot be used, two adjacent limiting gates can also limit the boar, thereby improving the convenience of boar positioning and thus improving the efficiency of estrus detection in sows.

[0022] Optionally, the front door has a receiving groove for accommodating the limiting door, and in the initial state, the limiting door is located in the receiving groove.

[0023] By adopting the above technical solution, the receiving groove accommodates the limiting door without affecting the overall appearance and structure of the front door.

[0024] Optionally, the positioning plate has an inlet groove that communicates with the first recess, and the limiting component includes:

[0025] A plug-in block is provided on the limiting gate. When rotated, the plug-in block enters the first groove through the inlet slot.

[0026] A magnet sheet, which is fixedly mounted on the plug-in block;

[0027] A metal part is disposed in the first groove and is positioned opposite to the inlet groove. After being rotated to the correct position, the magnet is attracted to the metal part. The limiting door isolates the limiting channel. The limiting door cooperates with the adjacent limiting door / limiting plate to limit the boar.

[0028] By adopting the above technical solution, when rotating, the plug-in block rotates synchronously with the limiting door. The plug-in block enters the first groove through the inlet slot and abuts against the first groove. The magnetic piece and the metal part are attracted together, thereby limiting the limiting door. After use, the limiting door is manually moved to separate the magnetic piece from the metal part, and then the limiting door is rotated into the receiving slot for storage. The limiting door and adjacent limiting doors or the plugged limiting plate can also limit the boar, thereby improving the convenience of boar positioning and thus improving the efficiency of estrus detection in sows.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Drive the sows into the sow gestation pen, ensuring their heads face the front door. After closing the front and rear doors, drive the boars used for estrus testing into the gestation channel. Each boar is assigned to 2-3 sows. Multiple positioning components block the gestation channel, with two adjacent positioning components positioning one boar. This eliminates the need for staff to hold barriers to gestate the sows during estrus testing. Staff only need to observe the sows' estrus status at the rear door, reducing labor costs and improving the efficiency of estrus detection.

[0031] 2. At the end of the estrus limiting channel, first insert one limiting plate into the first and second grooves to block the end of the limiting channel. Then, drive the boar into the limiting channel. According to the number of sows corresponding to each boar, insert the next limiting plate between the sow limiting pen and the auxiliary surface at a suitable location. Continue in this manner to limit the estrus of each boar. After the plates are inserted, the staff can leave to the tail gate to observe the sows' condition. After the estrus check is completed, move the limiting plate away from the first and second grooves, and then drive the boars back to the breeding area. This improves the convenience of limiting boars when checking sows for estrus, thereby increasing the efficiency of estrus checks.

[0032] 3. When boars need to be positioned without using the limiting plate, rotate the limiting gate so that it rotates to the positioning plate. The limiting component then limits the limiting gate. If the limiting plate is damaged and cannot be used, two adjacent limiting gates can also limit the boar, thereby improving the convenience of boar positioning and thus improving the efficiency of estrus detection in sows.

Unless otherwise specified, terms such as "rotational connection" and "rotationally mounted" in this application refer to common rotational installation methods in the prior art, and therefore will not be elaborated upon in this application.

[0040] Example 1

[0041] Reference Figure 1 A boar positioning device for estrus detection in sows includes a sow confinement pen 1 and an auxiliary surface 2. The sow confinement pen 1 is used to confine the sow. The front end of the sow confinement pen 1 has a front door 11 and the rear end has a tail door 12. The front door 11 faces the auxiliary surface 2 and forms a confinement channel 21 between the front door 11 and the auxiliary surface 2 for the boar to pass through. The confinement channel 21 is provided with a plurality of positioning components 3 for positioning the boar.

[0042] Reference Figure 1 and Figure 2 The sow gestation pen 1 has multiple sections. The front door 11 is rotatably located at the front end of the sow gestation pen 1, and the tail door 12 is rotatably located at the tail end of the sow gestation pen 1. When the sow is in the sow gestation pen 1, the sow's head faces the front door 11 and the sow's rump faces the tail door 12. The rotation and positioning methods of the front door 11 and the tail door 12 are consistent with those in the prior art. This application has not improved them and they are not within the scope of protection of this application. Therefore, this application will not elaborate on them.

[0043] Reference Figure 1 and Figure 3In this embodiment, the auxiliary surface 2 is described using the wall facing the front end of the sow confinement pen 1 as an example. In other feasible embodiments, the auxiliary surface 2 can be replaced by the side of the boar contact area (e.g., the fence) facing the sow confinement pen 1.

[0044] Reference Figure 1 , Figure 2 and Figure 3 The positioning component 3 includes a positioning plate 31, a positioning block 32, and a limiting plate 33. There are multiple positioning plates 31, and the number of positioning plates 31 is one more than the number of sow limiting pens 1. That is, two adjacent positioning plates 31 correspond to the railings of the sow limiting pens 1 located on both sides of the front door 11. The positioning plates 31 are fixed on the auxiliary surface 2 and extend vertically. In this embodiment, the positioning plates 31 are fixedly installed on the auxiliary surface 2 by bolts (not shown in the figure) and are set opposite to the railings of the sow limiting pens 1. The positioning plates 31 have a vertically extending first groove 311, which penetrates the top surface of the positioning plates 31 and the side of the positioning plates 31 facing the front door 11.

[0045] Reference Figure 1 , Figure 2 and Figure 3 Multiple positioning blocks 32 are provided, and the number of positioning blocks 32 corresponds one-to-one with the number of positioning plates 31. The positioning blocks 32 are fixed on the front rail of the sow limiting pen 1 and are positioned opposite to the positioning plates 31. The positioning blocks 32 have a vertically extending second groove 321, which is positioned opposite to the first groove 311 and penetrates the upper and lower surfaces of the positioning blocks 32 and the side of the positioning blocks 32 facing the positioning plates 31.

[0046] Reference Figure 1 , Figure 2 and Figure 3 A limiting block 13 is fixed on the front rail of the sow gestation pen 1. The number of limiting blocks 13 corresponds one-to-one with the number of positioning blocks 32. The limiting block 13 is located directly above the positioning block 32 and is opposite to the positioning plate 31. The limiting block 13 has a vertically extending third groove 131. The third groove 131 penetrates the upper and lower surfaces of the limiting block 13 and the side of the limiting block 13 facing the positioning plate 31. The third groove 131 is connected to the second groove 321.

[0047] Reference Figure 1 , Figure 2 and Figure 3 The limiting plates 33 are multiple and correspond one-to-one with the number of positioning plates 31. The limiting plates 33 are vertically inserted into the first groove 311, the third groove 131 and the second groove 321, and the bottom end of the limiting plates 33 abuts against the inner bottom wall of the first groove 311 and the second groove 321. A limiting space 34 for limiting the boar is formed between two adjacent limiting plates 33.

[0048] Reference Figure 1 The top of the limiting plate 33 is fixed with a handle 331 for easy leverage, and the auxiliary surface 2 is provided with multiple storage hooks 22. When the limiting plate 33 is not in use, the limiting plate 33 is hung on the storage hooks 22 through the handle 331.

[0049] Reference Figure 1 , Figure 2 and Figure 4 A limiting door 4 is provided on the front door 11. The rotation method of the limiting door 4 can be any of the existing technologies or the same as the rotation method of the front door 11. There is no restriction here. The limiting door 4 corresponds one-to-one with the front door 11. The limiting door 4 rotates toward the positioning plate 31. The end of the front door 11 facing the auxiliary surface 2 has a receiving groove 111 for accommodating the limiting door 4. In the initial state, the limiting door 4 is placed in the receiving groove 111. The positioning plate 31 has a limiting component 5 for limiting the limiting door 4.

[0050] Reference Figure 1 , Figure 2 and Figure 4 The positioning plate 31 has an inlet groove 312, and two inlet grooves 312 are provided at intervals above and below. Both inlet grooves 312 are connected to the first groove 311. The limiting component 5 includes a plug block 51, a magnet 52 and a metal part 53. Two plug blocks 51 are provided and correspond one-to-one with the inlet grooves 312. The two plug blocks 51 are fixed at intervals above and below on the side of the limiting gate 4 away from the rotating end. When rotating, the plug blocks 51 enter the first groove 311 through the inlet groove 312.

[0051] Reference Figure 1 , Figure 3 and Figure 4 Two magnet pieces 52 are provided and correspond one-to-one with the plug-in blocks 51. The magnet pieces 52 are fixed on the side wall of the corresponding plug-in block 51 near the positioning plate 31. Two metal parts 53 are provided and correspond one-to-one with the magnet pieces 52. The two metal parts 53 are arranged vertically and vertically on the inner wall of the first groove 311. At the same time, the metal parts 53 are arranged opposite to the corresponding inlet groove 312. When the limiting door 4 is rotated, the plug-in block 51 enters the first groove 311 through the inlet groove 312. The magnet pieces 52 and the metal parts 53 are attracted to each other. At this time, the limiting door 4 isolates the limiting channel 21. The limiting door 4 cooperates with the adjacent limiting door 4 or limiting plate 33 to limit the boar.

[0052] In this embodiment, the metal part 53 is an iron sheet. In other feasible embodiments, the metal part 53 can be any metal that can be attracted by the magnet sheet 52, such as iron, cobalt, nickel, steel, etc.

[0053] The working principle of Embodiment 1 of this application:

[0054] The sows are driven into the sow gestation pen 1, with one sow per pen and their heads facing the front door 11. After closing the front door 11 and the tail door 12, at the end of the gestation channel 21, one of the gestation plates 33 is inserted into the first groove 311, the third groove 131, and the second groove 321 to block the end of the gestation channel 21. Then, the boars are driven into the gestation channel 21. Based on the number of sows corresponding to each boar (ideally 2-3 sows per boar), another gestation plate 33 is inserted between the sow gestation pen 1 and the auxiliary surface 2 at a suitable position, or the corresponding gestation door 4 is rotated. The insertion block 51 enters the first groove 311 through the inlet groove 312, and the magnet 52 is attracted to the metal part 53. At this time, either the gestation plate 33 or the gestation door 4 can block the gestation channel 21. Depending on the actual situation, either the limiting plate 33 or the limiting gate 4 can be used to improve the applicability of the scenario. This can be done in a similar way to limit the estrus of each boar. After the installation is completed, the staff can leave to the tail gate 12 to observe the sow's condition. After the estrus check is completed, the limiting plate 33 is moved to disengage from the first groove 311, the third groove 131 and the second groove 321, and the limiting plate 33 is hung on the storage hook 22. Alternatively, the limiting gate 4 is moved to disengage the magnet 52 from the metal part 53, and the limiting gate 4 is rotated into the receiving slot 111 for storage. Then the boar can be driven back to the breeding area. This improves the convenience of limiting the boar when checking the sow's estrus during the estrus period. There is no need for staff to hold the baffle for limiting. Staff only need to observe the sow's estrus at the tail gate 12, which reduces labor costs and improves the efficiency of checking the sow's estrus.

[0055] Example 2

[0056] Reference Figure 1 A boar positioning device for estrus detection in sows, which differs from Embodiment 1 in that the front door 11 is designed without a limit door 4, and the partition of the limiting channel 21 is achieved only by the limiting plate 33, and the boar for estrus detection is limited by two adjacent limiting plates 33.

[0057] The working principle of Embodiment 2 of this application is basically the same as that of Embodiment 1, and will not be described again here.

[0058] Example 3

[0059] Reference Figure 1 A boar positioning device for estrus detection in sows, which differs from Embodiment 1 in that the positioning component 3 only includes a positioning plate 31, without the design of positioning block 32, limiting block 13, limiting plate 33 and storage hook 22. The partition of the limiting channel 21 is only achieved by limiting door 4, and the boar for estrus detection is limited by two adjacent limiting doors 4.

[0060] The working principle of Embodiment 3 of this application is basically the same as that of Embodiment 1, and will not be described again here.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
