A sow delivery and piglet nursing integrated delivery pen

Abstract

This application discloses an integrated farrowing pen for sows and piglets, comprising a bottom support frame and a pen frame located on top of the bottom support frame. A sow pen is housed within the pen frame and connected to the bottom support frame. The pen also includes: a first flooring layer laid on the bottom support frame and located at the bottom of the sow pen near the head; a second flooring layer laid on the bottom support frame, with other areas at the bottom of the sow pen also covered by the second flooring layer; and a third flooring layer laid on the bottom support frame, with areas inside the pen frame and located outside the sow pen. Multiple urine leakage holes are evenly spaced on the second and third flooring layers. The first flooring layer is thicker than the second flooring layer, and the second flooring layer is thicker than the third flooring layer. The greater thickness of the second flooring layer, by raising the area where the sow stands and lies down by 5-8 cm relative to the piglet's activity area, makes it easier for newborn piglets to suckle from the sow's inner teats, ensuring that piglets receive sufficient colostrum.

Description

Technical Field

[0001] This application relates to the field of farrowing pen technology, and in particular to a farrowing pen that integrates sow farrowing and piglet nursing. Background Technology

[0002] In the pig farm production process, sows are usually moved into the farrowing pen 5-7 days before their expected farrowing date. This early entry allows the sow to acclimatize to the pen environment, reducing stress caused by unfamiliar surroundings and preventing difficult farrowing due to tension. The sow completes the entire farrowing process within the pen. After farrowing, the sow continues to nurse her piglets in the pen until they are weaned at 21-28 days old. Only then is the sow moved out, and the piglets remain in their original pen or are transferred to the nursery for a few days.

[0003] In existing technology, the area where the sow stands or lies down in the farrowing pen is on the same horizontal plane as the piglets' activity area. However, the sow's abdomen is curved, and the inner teats are closer to the ground when the sow is standing or lying on her side. If the sow and piglets are on the same plane, the piglets need to raise their heads and arch their backs to latch onto the inner teats, which is a huge challenge for piglets that are small at birth and weak. This results in weak piglets not being able to get enough colostrum in time, leading to insufficient passive immunity and making them prone to diseases such as diarrhea and arthritis later on.

[0004] Therefore, it is necessary to propose an integrated farrowing pen for sows and piglets to facilitate piglets suckling colostrum, which has become an important technical problem that urgently needs to be solved. Summary of the Invention

[0005] This application provides an integrated farrowing crate for sows and piglets, aiming to solve the problem in existing farrowing crates where the area where the sow stands or lies down is on the same level as the area where the piglets move. However, the sow's abdomen is curved, and the inner teats are closer to the ground when the sow is standing or lying on her side. If the sow and piglets are on the same plane, the piglets need to arch their heads to latch onto the inner teats, which is a huge challenge for piglets with low birth weight and weak strength. This results in weak piglets not being able to get enough colostrum in time, leading to insufficient passive immunity and making them prone to diseases such as diarrhea and arthritis later on.

[0006] To achieve the above objectives, this application proposes an integrated farrowing pen for sows and piglets, comprising a bottom support frame and a pen frame located on the upper end of the bottom support frame. A sow pen is disposed within the pen frame and connected to the bottom support frame. The pen also includes: a first flooring layer laid on the bottom support frame and located at the bottom of the sow pen near the head; a second flooring layer laid on the bottom support frame, with other locations at the bottom of the sow pen also covered by the second flooring layer; and a third flooring layer laid on the bottom support frame, with locations inside the pen frame and outside the sow pen also covered by the third flooring layer. The second and third flooring layers have multiple urine leakage holes evenly spaced apart. The thickness of the first flooring layer is greater than that of the second flooring layer, and the thickness of the second flooring layer is greater than that of the third flooring layer.

[0007] In some embodiments, the device further includes: a first mounting plate disposed on the frame; a heat insulation cover connected to the first mounting plate; and an electric heating plate disposed on the bottom support frame, the electric heating plate being located below the heat insulation cover.

[0008] In some embodiments, it further includes: a lead wire electrically connected to the heating plate; a heat shrink tubing wrapped around the outside of the lead wire; a wiring trough formed in the bottom support frame, the wiring trough being located below the heating plate, and the heat shrink tubing and the lead wire being located inside the wiring trough; and a sealing strip disposed on the top of the wiring trough.

[0009] In some embodiments, the heating plate includes: a first heating line electrically connected to a lead wire and located in the edge region of the heating plate; and a second heating line electrically connected to a lead wire and located in the central region of the heating plate.

[0010] In some embodiments, the sow pen includes: two side bars spaced apart and mounted on a bottom support frame; a front door connecting the two side bars; two second mounting plates respectively disposed on both sides of the front door, the front door connecting the two side bars via the second mounting plates; a wraparound rear door connecting the two side bars; and two third mounting plates respectively disposed on both sides of the wraparound rear door, the wraparound rear door connecting the two side bars via the third mounting plates.

[0011] In some embodiments, the sow pen further includes: a first mounting frame disposed on a side rail; an anti-pressure bar disposed on the first mounting frame; and a plurality of first connecting holes spaced apart on the anti-pressure bar, wherein the anti-pressure bar is detachably disposed on the first mounting frame through the first connecting holes.

[0012] In some embodiments, the sow pen further includes: a fourth mounting plate disposed on a side bar; a fifth mounting plate disposed at an angle on the fourth mounting plate; a mounting frame connected to the fifth mounting plate; and a water bowl placed on the mounting frame.

[0013] In some embodiments, the sow pen further includes: a filter screen disposed inside a drinking bowl; and a water level sensor disposed at the bottom inside the drinking bowl, below the filter screen.

[0014] In some embodiments, the sow pen further includes: two second mounting frames spaced apart at the front door; two sixth mounting plates connected to the two second mounting frames in a one-to-one correspondence; and a sow feed trough connected to the two sixth mounting plates.

[0015] In some embodiments, it further includes a skateboard that is movably disposed within the frame.

[0016] This application proposes an integrated farrowing pen for sows and piglets, comprising a bottom support frame and a pen frame located on top of the bottom support frame. A sow pen is housed within the pen frame and connected to the bottom support frame. The pen also includes: a first flooring layer laid on the bottom support frame and located at the bottom of the sow pen near the head; a second flooring layer laid on the bottom support frame, with other areas at the bottom of the sow pen also covered by the second flooring layer; and a third flooring layer laid on the bottom support frame, with areas inside the pen frame and outside the sow pen covered by the third flooring layer. Multiple urine leakage holes are evenly spaced on the second and third flooring layers. The first flooring layer is thicker than the second flooring layer, and the second flooring layer is thicker than the third flooring layer. Farrowing and piglet nursing both occur within the farrowing pen, and the sow and piglets are separated within the farrowing pen by the sow pen, improving piglet survival rates. The second floor is thicker than the third floor. By raising the area where the sow stands and lies down by 5-8 cm relative to the piglets' activity area, it makes it easier for newborn piglets to suckle the sow's inner teats, ensuring that the piglets can get enough colostrum in time. The first floor is thicker than the second floor to provide specialized high support, open the sow's airway, reduce the sow's chest pressure, improve lung ventilation efficiency, and make the sow feel more comfortable when nursing.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] See Figure 1 , Figure 7 and Figure 9As shown, this application discloses an integrated farrowing pen for sows and piglets, comprising a bottom support frame 26 and a pen frame 1 disposed on the upper end of the bottom support frame 26. A sow pen is disposed within the pen frame 1 and connected to the bottom support frame 26. The pen also includes: a first floor 13, which is laid on the bottom support frame 26 and located at the bottom of the sow pen near the head; a second floor 11, which is laid on the bottom support frame 26 and is also laid at other locations at the bottom of the sow pen; and a third floor 8, which is laid on the bottom support frame 26 and is also laid at locations inside the pen frame 1 and outside the sow pen. The second floor 11 and the third floor 8 are provided with a plurality of urine leakage holes evenly spaced apart. The thickness of the first floor 13 is greater than that of the second floor 11, and the thickness of the second floor 11 is greater than that of the third floor 8.

[0021] The bottom support frame 26 is the structural foundation of the farrowing pen, and all other structures on the farrowing pen are directly or indirectly connected to the bottom support frame 26. The bottom support frame 26 is connected to the pigsty frame by welding. The pen frame 1 is connected to the bottom support frame 26 by screws and other fasteners. The pen frame 1 and the bottom support frame 26 enclose a farrowing area with an opening at the top, and each sow waiting to farrow moves into its corresponding farrowing area.

[0022] The sow pen is used to separate sows and piglets. Sows are located inside the pen, while piglets are outside. Sows typically weigh 200-300 kg and are clumsy, moving slowly and taking their time to get up and lie down. Newborn piglets, weighing only about 1.5 kg, are agile but have very short reaction times. Separating the sows and piglets effectively prevents the sow from crushing the piglets. Furthermore, sows and piglets require different environmental temperatures. Newborn piglets need 32℃-35℃, while sows only need 18℃-22℃. Separating the sows and piglets also allows for zoned temperature management, improving the survival rate of both sows and piglets.

[0023] The first floor 13, the second floor 11, and the third floor 8 are the core structures of the farrowing pen. The first floor 13 and the second floor 11 are used to support the sow, while the third floor 8 is used to support the piglets. The second floor 11 is thicker than the third floor 8. By raising the area where the sow stands and lies down by 5-8 centimeters relative to the piglets' activity area, on the one hand, it makes it easier for newborn piglets to suckle the sow's inner teats, ensuring that the piglets can get enough colostrum in time. On the other hand, it also creates a safe recessed hiding area under the sow's body, where piglets can quickly hide when the sow gets up or lies down, greatly reducing the risk of being crushed or trampled to death. Furthermore, the height difference effectively reduces direct contact between the sow's udder and the ground feces, keeping the udder area clean and dry, thereby reducing the incidence of piglet diarrhea and sow mastitis, and facilitating observation and assisting farrowing operations by the farmhands.

[0024] The first floor 13 is designed to support the sow's head. Thicker than the second floor 11, it provides specialized elevated support, opening the sow's airway, reducing chest pressure, improving lung ventilation efficiency, and making the sow more comfortable. Furthermore, because the first floor 13 is higher and the second floor 11 is lower, the sow is more inclined to move her hindquarters to the lower position for defecation, allowing excrement to drain more effectively from the urinary drain holes on the second floor 11. This effectively reduces fecal accumulation in the sow's head and chest area, maintaining the cleanliness of the sow's udder and piglet activity area, and reducing the incidence of mastitis and piglet diarrhea. Piglet feces flow through the urinary drain holes on the third floor 8.

[0025] The first floor 13 and the second floor 11 are made of stainless steel, while the third floor 8 is made of polypropylene. The third floor 8, made of polypropylene, is corrosion-resistant, fatigue-resistant, and moderately priced. Furthermore, plastic has a much lower thermal conductivity than metal, preventing heat loss from the piglets' abdomens when they lie down, thus reducing the risk of diarrhea. The plastic surface is also gentler than metal, reducing hoof wear and joint damage to the delicate hooves of piglets. The first floor 13 and the second floor 11, being thicker than the third floor 8, have sufficient structural strength to effectively support the sow.

[0026] Specifically, farrowing and piglet nursing both take place in the farrowing crate, and the sow and piglets are separated in the farrowing crate by the sow crate, improving the survival rate of piglets. The second floor 11 is thicker than the third floor 8. By raising the area where the sow stands and lies down relative to the piglet's activity area by 5-8 cm, it makes it easier for newborn piglets to suckle the sow's inner teats, ensuring that piglets can get enough colostrum in time. The first floor 13 is thicker than the second floor 11 to provide specialized high support, open the sow's airway, reduce the sow's chest pressure, improve lung ventilation efficiency, and make the sow feel more comfortable when nursing.

[0027] The first floor 13, the second floor 11, and the third floor 8 are all connected to the bottom support frame 26 by fasteners. The first floor 13 has a first chamfer 132 at the connection with the second floor 11, the first floor 13 has a second chamfer 131 at the connection with the third floor 8, and the second floor 11 has a third chamfer 111 at the connection with the third floor 8. The first chamfer 132, the second chamfer 131, and the third chamfer 111 can reduce stress concentration and prevent the board from cracking; they also eliminate dead corners where dirt and grime can accumulate; and they are also beneficial for protecting sows and piglets, preventing them from being scratched.

[0028] See Figure 1 , Figure 5 and Figure 7As shown, in some embodiments, the system further includes: a first mounting plate 14 disposed on the pen frame 1; the first mounting plate 14 is connected to the pen frame 1 by fasteners such as screws; a heat insulation cover 2 connected to the first mounting plate 14; the first mounting plate 14 is connected to the heat insulation cover 2 by screws to install the heat insulation cover 2 onto the pen frame 1; and an electric heating plate 12 is laid on the bottom support frame 26, located below the heat insulation cover 2. The electric heating plate 12 is used to heat the abdomen of the piglets, which helps digestion and absorption, reduces diarrhea, and enables the piglets to grow healthily.

[0029] The system includes an infrared imager, camera, and processor fixed to the railings. The camera and processor determine if the piglets have left the heating plate. After the piglets have been away from the heating plate for 12 minutes (1-2 minutes), the infrared imager obtains the temperature of the heating plate to prevent overheating. The heat preservation cover 2 contains infrared bulbs and a protective mesh. Infrared radiation can directly penetrate the air to heat the piglets' backs and entire bodies. Compared to the heating plate 12, which only heats the abdomen, this method raises the piglets' body temperature more quickly, making it especially suitable for newborn piglets to recover their vitality rapidly. Furthermore, the open-style heat preservation cover 2 and heating plate 12 can provide warmth to the piglets while maximizing their activity space.

[0030] Understandably, a third floor 8 will not be laid at the location where the electric heating plate 12 is laid.

[0031] See Figure 1 , Figure 5 , Figure 7 , Figure 10 and Figure 11 As shown, in some embodiments, it further includes: a lead wire electrically connected to the heating plate 12; the lead wire connected to the heating circuit inside the heating plate 12; and a heat shrink tubing 1211 wrapped around the outside of the lead wire; the heat shrink tubing 1211 is used to improve the insulation performance of the lead wire and prevent short circuits from occurring. The heat shrink tubing 1211 and the lead wire constitute the control wire 121 of the heating plate 12. A wiring trough 261 is located on the bottom support frame 26, below the heating plate 12. The heat shrink tubing 1211 and the lead wire are located within the wiring trough 261. The control wire 121 is led out from below the heating plate 12 and placed directly into the wiring trough 261. The wiring trough 261 is used to organize the control wires 121 of each farrowing pen. Because the wiring trough 261 is located below the heating plate 12, piglets cannot chew on the control wires 121, and piglet feces are difficult to enter the wiring trough 261, improving the reliability of the control wires 121. A sealing strip 28 is installed on the top of the wiring trough 261. The sealing strip 28 seals the wiring trough 261, further preventing the entry of feces or flushing water, ensuring the dryness inside the wiring trough 261, and further improving the reliability of the control wires 121.

[0032] In this embodiment, the wiring groove 261 is a stepped groove, and the sealing strip 28 is preferably T-shaped. The above structural arrangement can effectively increase the sealing area, ensure the dryness inside the wiring groove 261, and further improve the reliability of the control line 121.

[0033] See Figure 1 , Figure 5 , Figure 7 , Figure 10 and Figure 11 As shown, in some embodiments, the heating plate 12 includes: a first heating circuit, which is electrically connected to leads and located in the edge region of the heating plate 12; the first heating circuit includes a first male terminal 124 and a first female terminal 125; and a second heating circuit, which is electrically connected to leads and located in the central region of the heating plate 12. The second heating circuit includes a second male terminal 123 and a second female terminal 126. The first and second heating circuits are made of aluminum foil or copper foil. The first heating circuit has a higher power density, while the second heating circuit has a lower power density. The edge region of the heating plate 12 dissipates heat quickly, and its temperature is often 3-5°C lower than that of the center, which is not conducive to the healthy growth of piglets on it. If the overall power is increased to improve the edge temperature, the center is prone to overheating, and once it exceeds 42°C, it will burn the piglets' skin. The arrangement of the first and second heating circuits can effectively overcome the above-mentioned defects and avoid a large temperature gradient on the surface of the heating plate.

[0034] Both the first heating circuit and the second heating circuit are equipped with fuses 122.

[0035] See Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, in some embodiments, the sow pen includes: two side pens 6, which are installed at intervals on a bottom support frame 26; both side pens 6 are connected to the bottom support frame 26 by fasteners; the first floor 13 and the second floor 11 are provided with grooves to avoid the side pens 6; the two side pens 6 can be adjusted in position on the bottom support frame 26 to accommodate sows of different sizes. A front door 29 connects the two side pens 6; two second mounting plates 30 are respectively provided on both sides of the front door 29, and the front door 29 is connected to the two side pens 6 through the second mounting plates 30; the second mounting plates 30 are integrally formed on both sides of the front door 29, and the second mounting plates 30 are provided with second connecting holes at intervals; a third mounting bracket 31 is welded to both side pens 6, and the second connecting holes are connected to the third mounting bracket 31 by bolts. By connecting different second connecting holes, the spacing between the two side pens 6 can be adjusted. Preferably, two sets of second mounting plates 30 are provided at intervals in the height direction. A wraparound rear door 18 connects to two side rails 6. Two third mounting plates 16 are respectively located on both sides of the wraparound rear door 18, connecting the two side rails 6 via the third mounting plates 16. The wraparound rear door 18 has an outward protruding structure, providing ample space for the sow's rump, hind legs, and hooves, preventing contact between the vulva, hind legs, and hooves and the wraparound rear door 18, thus providing protection for the sow. A fourth mounting frame is welded to each of the two side rails 6. Multiple third connecting holes are spaced apart on the third mounting plates 16. A screw shaft 17 passes through the fourth mounting frame and the third connecting holes, and a ring 15 is provided at the upper end of the screw shaft 17. A locking nut is screwed to the bottom of the screw shaft 17, thereby connecting the fourth mounting frame to the third mounting plate 16. The spacing between the two side rails 6 can be adjusted by connecting different third connecting holes. Preferably, two sets of third mounting plates 16 are spaced apart in the height direction, and the screw shaft 17 on one side passes through the two third mounting plates 16 spaced apart in the height direction at the same time.

[0036] In this embodiment, in order to improve the reliability of the connection between the two side rails 6, a railing connecting rod 3 is also provided. Both ends of the railing connecting rod 3 are provided with a seventh mounting plate 5. The seventh mounting plate 5 is provided with a fourth connecting hole at intervals. The seventh mounting plate 5 is connected to the side rail 6 by screws. The fourth connecting hole at intervals is used to adapt to the change in the spacing between the side rails 6.

[0037] See Figure 1 , Figure 3 and Figure 7As shown, in some embodiments, the sow pen further includes: a first mounting frame 19, disposed on the side pen 6; an anti-pressure bar 7, disposed on the first mounting frame 19; and a plurality of first connecting holes 20, spaced apart on the anti-pressure bar 7, the anti-pressure bar 7 being detachably disposed on the first mounting frame 19 through the first connecting holes 20. The anti-pressure bar 7 is bolted to the first mounting frame 19. The anti-pressure bar 7 is used to restrict the sow's range of motion, and is installed on both sides of the side pen 6 at a height of approximately 20-30 cm above the ground. When the sow lies on her side or suddenly lies down, her heavy body is supported by the anti-pressure bar 7, forming a triangular safety zone between the sow's body and the slatted floor. Piglets, due to their smaller size, can quickly hide in this area, thus avoiding being crushed or killed by sows weighing over 200 kg. Furthermore, the anti-pressure bar 7 does not prevent piglets from finding the teats. Piglets can freely enter and exit the safety zone and nurse while the sow remains lying still on her side. If the sow moves slightly due to the stimulation of piglets suckling, the anti-crushing bar 7 can still restrict the sow's movement space, preventing the sow from suddenly jumping up and down and injuring the piglets. The extension length of the anti-crushing bar 7 can be adjusted by adjusting the position of the first connecting hole 20 connected to the first mounting frame 19, thereby adapting to sows of different parities, body sizes, and breeds, improving the practicality of the sow pen. Furthermore, adjustments can be made throughout the farrowing process. Before farrowing, the sow's abdomen is swollen and taut, requiring more abdominal space; at this time, the anti-crushing bar 7 can be appropriately moved outwards. After farrowing, the sow's abdomen contracts and droops, and the udder is full. At this time, the anti-crushing bar 7 can be appropriately retracted inwards, effectively reducing the dangerous space where piglets might be crushed and improving protection efficiency. In the later stages of lactation, as piglets grow larger, become more agile, and their self-protection abilities increase, the anti-crushing bar 7 can also be appropriately moved outwards to reduce the sow's feeling of constraint.

[0038] See Figure 1 , Figure 4 and Figure 7 As shown, in some embodiments, the sow pen further includes: a fourth mounting plate 21, which is disposed on the side pen 6; the fourth mounting plate 21 is welded to one side of the side pen 6; a fifth mounting plate 22, which is inclinedly disposed on the fourth mounting plate 21; the fifth mounting plate 22 is detachably mounted to the fourth mounting plate 21 by fasteners; a mounting frame 23, which is connected to the fifth mounting plate 22; the mounting frame 23 is specifically a ring frame; a water bowl 24 is placed on the mounting frame 23. The water bowl 24 is placed on the mounting frame 23, and the mounting frame 23 and the water bowl 24 are connected and fixed by welding. The water bowl 24 is set at a low height and is inclined towards the sow pen to facilitate the sow drinking water while nursing.

[0039] Understandably, the installation position of the fifth mounting plate 22 on the fourth mounting plate 21 can be adjusted to adjust the height of the water bowl 24 to accommodate sows of different parities, body sizes and breeds.

[0040] See Figure 1 , Figure 4 and Figure 7 As shown, in some embodiments, the sow pen further includes: a filter screen 25 disposed within a water bowl 24; the filter screen 25 is welded into the water bowl 24; and a water level sensor disposed at the bottom interior of the water bowl 24, below the filter screen 25. The water level sensor is detachably disposed at the bottom interior of the water bowl 24 and is used to monitor the water level within the water bowl 24. Preferably, a water supply pipe is suspended within the pigsty and faces the water bowl 24 to replenish water promptly when the water level is low. The filter screen 25 is provided to prevent sows from biting the water level sensor.

[0041] See Figure 1 , Figure 7 and Figure 8 As shown, in some embodiments, the sow pen further includes: two second mounting brackets 33, spaced apart at the front door 29; the second mounting brackets 33 are welded to the front door 29 and have through holes; two sixth mounting plates 34, which are connected to the two second mounting brackets 33 one-to-one; the sixth mounting plates 34 are provided with connecting screws 32, which pass through the through holes on the second mounting brackets 33 and are locked by locking bolts; and a sow feed trough 4, which is connected to the two sixth mounting plates 34. The two sides of the sow feed trough 4 are bolted to the sixth mounting plates 34. Since the connecting screws 32 are not screwed to the second mounting brackets 33, the sow feed trough 4 can be rotated appropriately, facilitating the turning and cleaning of the sow feed trough 4.

[0042] In this embodiment, the second mounting frame 33 includes multiple sets spaced apart along the height direction, which can adjust the height of the sow feed trough 4 according to sows of different parities, body sizes and breeds.

[0043] See Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the system further includes a sliding plate 10, which is movably mounted on the pen frame 1. The sliding plate 10 opens completely to facilitate the entry of sows into the pen and the exit of piglets. Two sliding frames are connected to the pen frame 1 by fasteners, and each sliding frame has a groove. The two sides of the sliding plate 10 are movably mounted within the groove. A gripping part 9 is provided at the top of the sliding frame, and the gripping part 9 has anti-slip texture. The gripping part 9 facilitates the opening of the sliding plate 10 by workers.
