Description

A pig digestion and metabolism cage

technical field

The utility model relates to the technical field of biological instruments, in particular to a pig digestion and metabolism cage, more specifically to a digestion and metabolism cage for pig digestion and metabolism experiments.

Background technique

Digestion and metabolism test is the main means to evaluate feed energy value and standard ileal amino acid digestibility. At present, researchers often use in vivo, semi-in vivo and in vitro methods to study the digestion and metabolism of pig feed nutrients. Among them, the in vivo method, which is characterized by the collection of feces, is the method that best reflects the real digestion and metabolism of pigs.

For the digestion and metabolism test of pigs with different weight stages and pigs with ileal fistula, the in vivo method can accurately record the feed intake of the pigs, and collect the feces and urine excreted by the test pigs as completely as possible, and ensure the pigs’ activity under the condition of restricting their activities. comfort. In addition, it is necessary to install a T-shaped fistula in a specific part of the digestive tract of the experimental pigs to collect chyme through surgery.

At present, traditional pig digestion and metabolism cages, based on the research on pig feeding behavior, feeding behavior and excretion behavior, can meet the comfort level of experimental pigs and can collect feces, urine and food samples under the conditions of pig welfare. However, it still has the defects of inaccurate measurement and incomplete collection of feces and urine, and it cannot satisfy the synchronicity of feeding and drinking of experimental pigs. When the test pigs are weighed, they cannot be directly weighed. Therefore, weighing the test pigs during the test has the disadvantages of time-consuming, laborious and inaccurate. Therefore, in view of the above deficiencies, it is necessary to provide a digestion and metabolism cage that can be used for digestion and metabolism tests of pigs of different weight stages and ileal fistula pigs.
