Description

Technical Field

[0001] The utility model belongs to the technical field of livestock metabolism test instruments, in particular to a metabolic cage for black Tibetan sheep. Background Technique

[0002] The metabolic cage is an essential experimental tool for studying the apparent digestibility of animal feed in traditional animal nutrition, mainly used for collecting feces and urine excreted by experimental animals. The horns of black Tibetan sheep are large and extend outwards, which have certain requirements for the dimensions of the fences above, on the left and right sides of the feeding trough. The traditional meat sheep metabolic cage cannot ensure its normal feeding. Moreover, the body sizes of black Tibetan sheep at different ages are inconsistent. If a metabolic cage with a unified size is used, it will cause inappropriate heights of the feeding trough and water trough, affecting the feeding and drinking of the experimental sheep. A too large cage body will cause the smaller lambs to move around randomly in the cage, increasing the risk of their feces and urine being discharged into the feeding trough and water trough. If metabolic cages are designed separately for each stage, the cost is too high. When conducting feeding experiments on black Tibetan sheep, if large-scale group feeding is adopted, it will inevitably result in the situation that the "strong sheep" eat more and the "weak sheep" eat less, affecting the accuracy of the feeding experiment results. Therefore, single-stall feeding can improve the accuracy of the feeding experiment. Content of the Utility Model

[0003] The purpose of the utility model is to provide a metabolic cage for black Tibetan sheep, which is convenient for black Tibetan sheep of different body sizes to feed normally and collect feces and urine, is more flexible to use, and improves the accuracy of feeding experiment results.

Threaded holes are opened on the side walls of the two columns 1, and first screws 8 that are in threaded fit with the threaded holes are inserted into the threaded holes. The tightening end of the first screw 8 abuts against the side wall of the slider 22. A fixing groove is opened on the movable plate 17, and a feeding trough 9 is arranged in the fixing groove. A partition plate 18 for separating the feeding trough 9 into a water trough and a feed trough is arranged in the feeding trough 9. A fecal sample collection filter screen 4 for collecting feces is obliquely arranged below the wire mesh 13, and a urine collection basin 2 for collecting urine is arranged below the fecal sample collection filter screen 4; vertical columns 1 are welded or pasted on the left and right side walls of the two side bars 5, a top bar 15 is welded or pasted on the tops of the two side bars 5, a wire mesh 13 is welded or pasted on the bottoms of the two side bars 5, a gate 14 is arranged on the right side wall of the two side bars 5, one side of the gate 14 is hinged to one of the columns 1 through a first hinge, and the other side of the gate 14 is threadedly connected with a first buckle 6. The first buckle 6 is a prior art. The hook of the first buckle 6 is fixed to the side wall of the gate 14 by threading, and the buckle of the first buckle 6 is threadedly connected to the side wall of the column 1. The buckle of the first buckle 6 hooks the hook to lock, so as to fix the gate 14 and the column 1. When digestive metabolism experiments need to be carried out on black Tibetan sheep, the buckle of the first buckle 6 is loosened from the hook, and the gate 14 is rotated to rotate around the hinge of the first hinge, so that the black Tibetan sheep can enter the two side bars 5. There is a moving distance from the column 1 to the wire mesh 13, and a movable step can be placed at the gate 14 to facilitate the black Tibetan sheep to enter the two side bars 5 through the step;

[0022] The column 1 is a square tube, and the side bar 5 is made of a mesh with an aperture of 15 cm * 15 cm. Its aperture can prevent black Tibetan sheep from escaping; the wire mesh 13 is made of a steel wire mesh with an aperture of 2 cm * 2 cm. Its aperture can not only prevent the hooves of lambs from falling or getting stuck, but also ensure that sheep feces fall through the aperture;

[0023] The left side walls of the two side fences 5 are provided with moving plates 17. The front and rear side walls of the moving plate 17 are welded or pasted with sliders 22. Corresponding to the two sliders 22, chutes are opened on the rear side wall of the front column 1 and the front side wall of the rear column 1. The two chutes extend to the top of the column 1. During use, the sliders 22 are slid into the chutes from top to bottom, so that the moving plate 17 is fixed between the two front and rear columns 1. The moving plate 17 moves up and down between the two columns 1. Threaded holes are opened on the side walls of the two columns 1, and first screws 8 that are in threaded cooperation with them are inserted into the threaded holes. The tightening ends of the first screws 8 abut against the side walls of the sliders 22. Tighten the first screws 8 so that their tightening ends abut against the side walls of the sliders 22. The frictional force between the tightening ends of the first screws 8 and the side walls of the sliders 22 fixes the positions of the sliders 22 in the chutes, thereby fixing the position of the moving plate 17. Loosen the first screws 8 so that their tightening ends release the abutment against the side walls of the sliders 22, and the sliders 22 slide up and down in the chutes, causing the moving plate 17 to move up and down, thereby driving the feeding trough 9 to move up and down. The height of the side fence 5 is lower than the height of the moving plate 17. After the moving plate 17 moves, the feeding trough 9 is also located between the two side fences 5, which is better for feeding the black Tibetan sheep;

[0024] The side wall of the movable plate 17 is provided with a fixing groove, and the bottom of the fixing groove is welded or pasted with a feeding trough 9 with an upward opening. A partition plate 18 is arranged in the feeding trough 9 for dividing the feeding trough 9 into a water trough and a feed trough. The partition plate 18 is welded or pasted in the feeding trough 9 to divide the feeding trough 9 into a water trough and a feed trough, where the feed trough is located at the front side and the water trough is located at the rear side. Drinking water is injected into the water trough to facilitate the black Tibetan sheep to drink water, and feed is placed in the feed trough to facilitate the black Tibetan sheep to eat; a gap for facilitating the black Tibetan sheep to eat is arranged between the top of the fixing groove and the top of the feeding trough 9. The gap between the top of the fixing groove and the top of the feeding trough 9 is convenient for the head of the black Tibetan sheep to stretch out to eat the feed or drinking water in the feeding trough 9; during use, according to the body size of the black Tibetan sheep, the position of the feeding trough 9 is adjusted. When the black Tibetan sheep is a lamb, the position of the feeding trough 9 is the lowest, which is convenient for the smaller-sized lamb to eat without effort; when the black Tibetan sheep is an adult ewe, the height of the feeding trough 9 can be increased; when the black Tibetan sheep is an adult ram, the height of the feeding trough 9 is the highest, which is convenient to adjust the position of the feeding trough 9 according to the black Tibetan sheep of different body sizes and convenient for the black Tibetan sheep to eat freely; and a groove is arranged at the top of the fixing groove, and an adjusting plate 24 is arranged in the groove. A second threaded hole is arranged on the side wall of the movable plate 17, and a second screw 23 in threaded fit with it is arranged in the second threaded hole. The tightening end of the second screw 23 abuts against the adjusting plate 24. A groove is arranged at the top of the fixing groove, and the adjusting plate 24 is embedded in the groove. The adjusting plate 24 moves up and down in the groove.

When the lamb eats, the gap between the bottom of the adjusting plate 24 and the top of the feeding trough 9 is the smallest, which is suitable for the head of the lamb to stretch out of the fixing groove to eat the feed and drinking water in the feeding trough 9. When the adult black Tibetan sheep eats, the gap between the bottom of the adjusting plate 24 and the top of the feeding trough 9 is the largest, which is convenient for the head of the adult black Tibetan sheep to stretch out of the fixing groove to eat the feed and drinking water in the feeding trough 9, enabling the black Tibetan sheep of different body sizes to eat better;

[0025] Below the missing net 13, a fecal sample collection filter screen 4 for collecting feces is inclined. Below the fecal sample collection filter screen 4, a urine collection basin 2 for collecting urine is provided. The fecal sample collection filter screen 4 is inclined. The fecal sample collection filter screen 4 is made of a fine wire mesh with a pore size of 1.6mm * 1.6mm to ensure blocking the feces excreted by black Tibetan sheep, and the urine flows through the pores. The left side of the fecal sample collection filter screen 4 is lower than the right side. When the head of the black Tibetan sheep is at the feeding trough 9 on the left side for feeding, the feces excreted by the black Tibetan sheep fall onto the fecal sample collection filter screen 4 through the missing net 13. The inclination angle of the fecal sample collection filter screen 4 is 10°, ensuring that the feces excreted by the black Tibetan sheep can roll to the left side of the fecal sample collection filter screen 4 to collect the feces, and also preventing the feces from being contaminated by urine, facilitating the staff to detect the apparent digestibility of the black Tibetan sheep through the feces and understand the digestion situation of the black Tibetan sheep for the fed materials. The urine collection basin 2 below the fecal sample collection filter screen 4 collects the urine of the black Tibetan sheep. The urine collection basin 2 is inclined, and the right side of the urine collection basin 2 is lower than the left side. The inclined urine collection basin 2 facilitates the urine to converge to the right side of the urine collection basin 2 to collect the urine of the black Tibetan sheep.

[0026] Moreover, a through hole is provided on the right side wall of the urine collection basin 2. At the through hole, a urine collection tube 19 is provided. The water outlet end of the urine collection tube 19 is threadedly connected with a urine collection bottle. The urine flows to the right side of the urine collection basin 2 and flows through the urine collection tube 19 to the urine collection bottle to collect the urine of the black Tibetan sheep and detect it, avoiding urine evaporation and pollution.

[0027] Below both the urine collection basin 2 and the fecal sample collection filter screen 4, there are two limiting strips 3 fixed to the side wall of the column 1 and distributed left and right. On the right side wall of the two front and rear distributed columns 1 on the left side, two limiting strips 3 distributed up and down are welded or pasted. On the left side wall of the two columns 1 on the right side, two limiting strips 3 are welded or pasted. Among them, the height of the upper limiting strip 3 on the left side is lower than the height of the upper limiting strip 3 on the right side, making the left side of the fecal sample collection filter screen 4 lower than the right side. Placing the fecal sample collection filter screen 4 on the two upper limiting strips 3 can support the fecal sample collection filter screen 4, facilitating the collection of the feces of the black Tibetan sheep. The height of the lower limiting strip 3 on the right side is lower than the height of the lower limiting strip 3 on the left side, making the right side of the urine collection basin 2 lower than the left side. The urine collection basin 2 is placed on the two lower limiting strips 3 to support the urine collection basin 2, facilitating the collection of the urine of the black Tibetan sheep. The urine collection basin 2 and the fecal sample collection filter screen 4 are detachably installed on the column 1. When it is necessary to detect the feces and urine of the black Tibetan sheep, their feces and urine can be collected, making its use more flexible. A baffle 20 for blocking the falling of feces is provided on the side wall of the fecal sample collection filter screen 4. The baffle 20 is welded or pasted on the left side wall of the fecal sample collection filter screen 4.

[0029] As Figure 1 , Figure 2 and Figure 3As shown in the figure, two partition fences 16 distributed front and back are hinged at the bottom of the top fence 15. The partition fences 16 are connected to the side fences 5 through snap rings 7. The partition fences 16 are made of a steel wire mesh with a pore size of 15 cm * 15 mm. Two partition fences 16 are hinged at the bottom of the top fence 15 through the third hinge. The partition fences 16 are connected to the side fences 5 through snap rings 7. The snap ring 7 is a prior art. The snap ring 7 includes a U-shaped frame with a threaded hole. A screw rod is inserted into the threaded hole. The U-shaped frame is hooked on the side fence 5 and the partition fence 16, and then the screw rod is threadedly connected to the threaded hole of the U-shaped frame, so as to fix the partition fence 16 and the side fence 5. The front side wall of the front partition fence 16 is connected to the front side fence 5 through a snap ring 7. The rear side wall of the front partition fence 16 is connected to the front side wall of the rear partition fence 16 through a snap ring 7. The rear side wall of the rear partition fence 16 is connected to the rear side fence 5 through a snap ring 7. The state of the partition fence 16 is adjusted according to the body types of different black Tibetan sheep. When the black Tibetan sheep is a lamb, one of the partition fences 16 is rotated to rotate around the hinge point to make it in a horizontal state, and then the partition fence 16 is connected to the top fence 15 by using the snap ring 7 to reduce the distance between the two side fences 5 and limit the activity range of the lamb. Or the two partition fences 16 are rotated to a vertical state and connected to the side fences 5 through the snap ring 7, so as to shorten the distance between the partition fence 16 and the feeding trough 9, making it impossible for the lamb to turn around freely and preventing it from discharging feces and urine into the water trough and feed trough of the feeding trough 9. When the two partition fences 16 are in a horizontal state, the distance between the two side fences 5 and the distance between the moving plate 17 and the gate 14 are convenient for adult black Tibetan sheep to feed and have a certain activity space. However, the width between the two side fences 5 is not convenient for adult black Tibetan sheep to turn around, avoiding the pollution of the feces and urine of the black Tibetan sheep and enabling better collection of them, improving the accuracy of the feeding test data of the black Tibetan sheep;
