A fully automatic monogastric animal bionic digestion instrument

Abstract

The invention relates to a fully automatic monogastric-animal bionic digestion apparatus which comprises a case, a constant-temperature air bath shaking table device, a bionic digestion device, an automatic enzyme adding device, a buffer solution circulating device, a washing device and a control circuit, wherein a digestion reaction chamber is arranged at the upper-left part of the case, and the constant-temperature air bath shaking table device and the bionic digestion device are arranged in the digestion reaction chamber; the automatic enzyme adding device is fixedly mounted on the case and connected with the bionic digestion device through a liquid transmitting tube; the buffer solution circulating device and the washing device are arranged under the case and respectively connected with the bionic digestion device through the liquid transmitting tubes; the control circuit is arranged under the case and connected with the constant-temperature air bath shaking table device, the automatic enzyme adding device, the buffer solution circulating device and the washing device through conducting wires. The fully automatic monogastric-animal bionic digestion apparatus can realistically simulate the process that fodder is digested and absorbed in the gastrointestinal tract of a monogastric animal.

Description

technical field [0001] The invention relates to the field of biological experiment instruments, in particular to a fully automatic monogastric animal bionic digestion instrument. Background technique [0002] In the modern aquaculture industry, objectively and accurately assessing the nutrient biological value of feed ingredients is the main decision-making basis for determining animal nutritional requirements and optimizing feed formulations. Given the wide variety of feed ingredients in my country and the fast update speed, it would take at least several decades to fully measure and predict the biological potency of feed nutrients using animal experiments, but only very limited static parameters can be obtained as a result. Therefore, in order to break through the technical bottleneck restricting the update of feed nutrient biological potency parameters in our country, it is urgent to design a scientific, accurate and rapid feed nutrient biological potency test tool, which...

Problems solved by technology

However, these bionic digestive systems were originally designed for the study of microbial growth in the gastrointestinal tract, pharmacological metabolism, etc., and are not suitable for determining the digestibility of feed energy, protein, and amino acids.

This is mainly because the digestive tract of this type of bionic device is relatively long, and the feed flows through the various segments of the digestive tract sequentially, which can easily cause blockage and residual feed in a certain segment of the bionic digestive tract.

In terms of design theory, these systems also cannot meet the concept of "all in, all out" in the determination of biological potency of feed nutrients
