Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and in particular to a digestive and metabolic test bag. Background Technology

[0002] The degradation characteristics of feed ingredients in the rumen refer to the process by which feed ingredients are broken down by microorganisms in the rumen and the degradation of their nutrients. This process has a significant impact on animal digestion, absorption, and nutrient utilization. In studies on the rumen degradation characteristics of commonly used feed ingredients for cattle and sheep, a comparative method using nylon bags is generally employed. In this method, samples are placed in nylon bags, tied to a tube, and then placed inside the rumen of cattle or sheep for digestion, with one end of the tube protruding from the animal's body. During the experiment, the tube can easily enter the rumen, leading to experimental failure and potentially causing damage to the digestive system. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a digestive and metabolic test bag that allows the bag to be fixed inside the rumen, preventing the connecting tube from entering other digestive systems, ensuring the smooth conduct of the experiment, and guaranteeing the safety of cattle and sheep.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A digestion and metabolism test bag includes a connecting tube and a limiting ring. The connecting tube is divided into several fixing parts. Each fixing part is tied with at least two bag bodies, and each bag body in the fixing part contains feed of the same weight, the same mesh size and the same type.

[0006] A connecting ring is fixedly provided at one end of the connecting tube. The connecting ring is connected to the limiting ring by a connecting rope. By connecting multiple connecting ropes of the connecting tubes to the limiting ring, different test groups can be formed.

[0007] Furthermore, the inner and outer walls of the limiting ring are both recessed with multiple slots, and the end of the connecting rope away from the connecting ring is tied inside the slot.

[0008] Furthermore, one end of the bag body is provided with a bag opening, and the end of the bag body folded up near the bag opening is tied to the connecting tube with a strap.

[0009] Furthermore, each of the fixing parts is provided with a connection port, which extends through the two opposite sides of the connecting tube. The end of the bag body near the bag opening passes through the connection port and is then folded over so that the strap can be tied to the bag body on the side of the connection port.

[0010] Furthermore, the bag body is made of nylon.

[0011] Furthermore, the connecting tube is a silicone tube.

[0012] The beneficial effects of this utility model are:

[0013] The two ends of the connecting rope are tied to the connecting ring and the limiting ring respectively. The limiting ring can limit the connecting tube, fixing the bag inside the rumen and effectively preventing the connecting tube from entering other parts of the digestive system, ensuring the smooth progress of the experiment and the safety of the cattle and sheep. By wrapping and tying the connecting rope inside the clamp, the connecting ropes corresponding to each connecting tube are evenly spaced and fixed to the limiting ring, avoiding the connecting ropes from becoming tangled or knotted. When removing the connecting tube, it can be ensured that the corresponding connecting rope is cut accurately to obtain the desired bag on the connecting tube. Attached Figure Description

[0021] Please participate at the same time Figures 1 to 3 The digestion and metabolism test bag of this utility model, according to a preferred embodiment, includes a connecting tube 1 and a limiting ring 2.

[0022] The connecting tube 1 is divided into several fixing parts 101, each fixing part 101 is tied with at least two bags 3, and each bag 3 of the fixing part 101 contains feed of the same weight, same mesh size and the same type. In this embodiment, the bag 3 is made of nylon and has a mesh size of 300. The connecting tube 1 is a silicone tube, which can reduce the harm of the connecting tube 1 to cattle and sheep.

[0023] A connecting ring 11 is fixedly installed at one end of the connecting pipe 1. The connecting ring 11 is connected to the limiting ring 2 through the connecting rope 12. By connecting the connecting ropes 12 of multiple connecting pipes 1 to the limiting ring 2, different test groups can be formed.

[0024] In this embodiment, the two ends of the connecting rope 12 are respectively tied to the connecting ring 11 and the limiting ring 2, so that the limiting ring 2 can limit the connecting tube 1, effectively fix the connecting tube 1 in the rumen, prevent the connecting tube 1 from entering other digestive systems, ensure the smooth progress of the experiment, and ensure the safety of cattle and sheep.

[0025] like Figure 1 As shown, the inner and outer walls of the limiting ring 2 are recessed with multiple slots 201, and the end of the connecting rope 12 away from the connecting ring 11 is tied inside the slot 201. By wrapping and tying the connecting rope 12 inside the slot 201, the connecting ropes 12 corresponding to each connecting tube 1 can be evenly spaced and fixed on the limiting ring 2, avoiding the connecting ropes 12 from becoming messy and tangled. When removing the connecting tube 1, it can be ensured that the corresponding connecting rope 12 is accurately cut to obtain the bag body 3 on the desired connecting tube 1.

[0026] like Figure 1 and Figure 2 As shown, one end of the bag body 3 is provided with a bag opening 301. After the bag body 3 is folded over and the end near the bag opening 301 is tied to the connecting tube 1 by a strap 31.

[0027] like Figure 3As shown, each fixing part 101 is provided with a connecting port 102. The connecting port 102 passes through the opposite sides of the connecting tube 1. The end of the bag body 3 near the bag opening 301 passes through the connecting port 102 and is then folded over so that the strap 31 can be tied to the bag body 3 on one side of the connecting port 102.

[0028] By inserting the bag body 3 through the connecting port 102, then folding the bag opening 301 and securing it with the strap 31, the bag body 3 can be prevented from slipping out of the connecting tube 1, while the bag opening 301 of the bag body 3 can be sealed to prevent feed from leaking out and ensure the accuracy of the test.

[0029] The experimental procedure for the digestive and metabolic test bag in this embodiment is as follows:

[0030] 1. After numbering the bags, soak them in clean water for 5 minutes, dry them at 65℃ for 24 hours until constant weight is achieved, and then weigh and record the weight.

[0031] 2. Accurately weigh 4g of feed substrate, and place the crushed feed substrate that has passed through a 10-mesh sieve at the bottom of bag 3;

[0032] 3. Three replicates of each feed substrate (one cow per replicate), four parallels per replicate, two parallel samples tied to the fixing part 101, the connecting ring 11 connected to the limiting ring 2 by the connecting rope 12, and a knot mark tied at the end of the connecting rope 12 near the limiting ring 2; seven connecting tubes 1 tied in the same way are prepared for each cow.

[0033] 4. Before morning feeding, insert all bags 3 into the rumen via a fistula. Following the principle of "simultaneous insertion and sequential removal," remove one connecting tube 1 from the rumen of each cow at 3, 6, 12, 24, 36, 48, and 72 hours. Immediately place both bags 3 of each sample into an ice box to stop digestion. Gently rinse the outer wall of the bag with tap water until the water is clear. After rinsing, place it in a 65℃ oven for 48 hours until constant weight. After weighing, pack it into sample bags and seal them at room temperature for the determination of nutritional indicators after rumen digestion. For the other two bags 3, pour PBS buffer into the nylon bag opening and rinse twice to remove loosely attached microorganisms. Pack the degradation residue into 5ml sterile test tubes, freeze them in liquid nitrogen, and refrigerate them at -80℃ after returning to the laboratory. These samples are used for the determination of feed-adhering microorganisms.
