Biomimetic test device for animal digestion and metabolism

Abstract

The invention relates to the field of animal breeding research and particularly relates to an animal digestion and metabolism bionic test device. The device comprises a breeding pen and a gross weight weighing apparatus connected with the breeding pen. A waste collection apparatus and a urine collection apparatus are arranged on the lower portion of the breeding pen, wherein the waste collection apparatus comprises a waste collection plate, and the urine collection apparatus comprises a urine collection container, a urine leading plate for leading urine in the breeding pen into the urine collection container and a urine weighing apparatus connected with the urine collection apparatus. Besides, a feeding region is arranged in the breeding pen, and an animal weighting apparatus is arranged in the feeding region. According to the device, weight change, waste weight and urine weight parameters of test animals can be obtained respectively, relevant parameters are provided for test research, interference in animals by men is not required during the parameter obtaining, and difficulties of animal digestion and metabolism bionic tests are reduced.

Description

technical field [0001] The invention relates to the field of animal breeding research, in particular to a bionic test device for animal digestion and metabolism. Background technique [0002] In the field of animal nutrition, the determination of nutrient and energy digestibility of animals is achieved through digestion tests. After the nutrients or energy are absorbed, part of them will be excreted from the urine after being metabolized in the animal body. On the basis of increasing the collection of urine, the nutrients and energy of excreta in urine are determined, which is called metabolic test, which is used for the determination of feed metabolizable energy or nutrient metabolic rate. [0003] The traditional pig digestion and metabolism test method is to put the test animals in metabolic cages, and collect all the feces and urine of the pigs during the test period by the method of total collection of feces and urine for laboratory analysis. The traditional metabolic ...

Problems solved by technology

Because this test method confines the animals in a narrow space, the animals cannot move freely and are in a state of stress, and the test results are difficult to represent the nutrient utilization of the animals under normal physiological conditions, that is, the test results are unreliable.

On the other hand, using traditional metabolic cages, the entire test process is manually operated. For growing pigs, especially pigs in the late growth period, due to their large size and weight, there are certain difficulties in manual operation.
