Problems solved by technology

In addition, in order to obtain weight growth parameters, it is usually necessary to frequently drive the test pigs out of the digestive and metabolic cages for weighing, so that the test pigs have a stress response and cause experimental errors
[0003] The current digestion and metabolism cages are relatively simple and primitive, the growth environment of the test pigs is poor, it is difficult to completely separate and collect the feces and urine, and it is impossible to automatically record the weight changes and feed intake of the pigs during the test
During the test, a lot of manpower is required, labor-intensive, time-consuming, and the measurement is not accurate, timely, and unscientific

Abstract

The invention provides an automatic weighing digestion metabolism cage for pigs and application thereof. The metabolism cage comprises a base, a feeding cage, a feed trough and a duck bill-type water trough, wherein the feed trough can be fixed on the feeding cage in a sliding mode, and the feeding cage is connected with the base by four weighing sensors. The cage can automatically monitor the weight change of test pigs, fully separate and collect stool and urine in real time, accurately measure the feed intake and improve the comfort of test pigs during breeding.

Description

technical field [0001] The invention relates to the technical field of swine nutrition research, belongs to a test device for swine digestion and metabolism, and can be used for digestion and metabolism tests of pigs with different stages, different body sizes and fistulas. Background technique [0002] In order to study the digestion and metabolism of nutrients in pig feed, researchers often use in vitro, semi-in vivo and in vivo methods for research. Among them, in vivo methods can best reflect the utilization of nutrients in animal feeds. Total excrement collection is the most commonly used test method in vivo. The digestion and metabolism of nutrients in the feed is determined by collecting feed samples and separately collecting the digestive metabolites (feces, urine) of the test pigs. Therefore, it is necessary to feed the test pigs. They were fed in special digestion and metabolism cages, so as to collect the digestive metabolites of the test pigs as completely as pos...
