Monogastric animal bionic digestion system and method for simulating monogastric animal digestion based on the system

Abstract

The invention discloses a single stomach animal biomimetic digestion system and the method for simulating the single stomach animal digestion. The system comprises: at least one simulated digestion device disposed on the fixed pawl of the air bath shaking table, at least one digestive juice bottle connected with the liquid transport tube; a main peristaltic pump connected with the input pipe; a waste liquid accepting bottle connected with the main peristaltic pump, at least one buffer liquid bottle connected with the main peristaltic pump and the output pipe; a cleaning fluid bottle connectedwith the main peristaltic pump, the cleaning fluid bottle is also connected with the output pipe, the cleaning fluid storage bottle and the lower residual cleaning fluid accepting bottle; the outputpipe is connected with or isolated from air through a connection control electromagnetic valve. The method comprises preparation and biomimetic digestion steps; the biomimetic digestion step comprises: injecting digestive juice, cycling buffer liquid, removing buffer liquid and cleaning residual liquid. The system and method in the invention realizes the the external simulation of the forage digestion and absorption process in animal gstrointestinal tract, achieves high fidelity and good repeatability.

Description

technical field [0001] The invention relates to a bionic digestive system of monogastric animals and a method for simulating digestion of monogastric animals based on the bionic digestive system of monogastric animals, in particular to a method for simulating feed in the gastrointestinal tract of monogastric animals under in vitro conditions Biomimetic digestive system and method for being digested and absorbed. 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 ...

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
