Digestibility and metabolism experiment device for lambs

Abstract

The invention relates to the technical field of biological appliances, in particular to a digestibility and metabolism experiment device for lambs. The experiment device comprises a cage body and a manure and urine separating device, wherein a first regulation control railing and a second regulation control railing used for regulating the width of the cage body are respectively arranged at the two sides of the cage body, a third regulation control railing used for regulating the length of the cage body is arranged between the first regulation control railing and the second regulation control railing, and an ascending and descending platform used for carrying animals to be tested is arranged at the bottom of the cage body. A urine collecting funnel and a manure collecting funnel are respectively and glidingly arranged on a longitudinal guide rail, the longitudinal guide rail is glidingly arranged under the ascending and descending platform through a transverse guide rail, the urine of the animals to be tested is collected by moving the urine collecting funnel, and the manure of the animals to be tested is collected by moving the manure collecting funnel. The experiment device has the advantages that the crossed pollution of the manure and the urine can be avoided, in addition, the experiment can be carried out on the lambs with different day ages and lambs in different body contours, the regulation is convenient, and the animals to be tested can conveniently go into or go out of the cage body.

Description

technical field [0001] The invention relates to the technical field of biological instruments, in particular to a digestion and metabolism experiment device for lambs. Background technique [0002] With the increasing demand for mutton consumption in the market, my country's sheep industry has developed rapidly. In order to shorten the lactation period of lambs and the breeding interval of ewes, improve the intensive breeding effect of lambs, and improve the economic benefits of lamb feeding, the nutrition, feed and feeding of early weaned lambs have been paid attention to, so there are many related experimental studies. [0003] At present, researchers usually use the in vivo method to study the digestion of nutrients in lambs, and most of the nutritional metabolism experiments on lambs use male lambs as test animals. During the test, it is inevitable to encounter the problem of collecting feces and urine. In the early experiments, people used feces bags to collect lamb f...

AI Technical Summary

Problems solved by technology

Therefore, the above two metabolic cages can only realize the separation of feces and urine, but cannot solve the problem of cross-contamination of feces and urine, resulting in inaccurate follow-up test results

At the same time, the above two metabolic cages are only designed for adult sheep, and the activity space (including length and width) in the cage cannot be adjusted in all directions, and cannot meet the characteristics of small early weaned lambs (feces and urine are not easy to form, and lambs are small in size) Design, resulting in limited experimental subjects, not universal
