Broiler external digestion simulating device

Abstract

The present invention provides an in vitro simulator which can simulate digestion and absorption processes of feed nutrient in the chicken alimentary tract, including maw and peptic digest chamber, small intestine digesting chamber and constant temperature system etc. The feed nutrient is completed by the maw and peptic digest chamber under the digesting course of the maw and peptic; chyme is converted to the small intestine digesting chamber continuously digested after the period of maw and peptic digestion, completing the digestion of the nutrient in the small intestine and the absorption of the digested nutrient, finally achieving the simulation of the digestion and absorption processes of the feed nutrient in the chicken alimentary tract in vitro; the constant temperature system provides heat preservation and vibrating mixture functions for the digestion course of the chyme in the maw, peptic digest chamber, small intestine digesting chamber, simulating the environment temperature of the chicken alimentary tract, gastrointestinal peristalsis and chyme mixture. The chicken in vitro simulating digestion device of the invention has a lower cost, simple operation, quick performance and better palingenesis.

Description

technical field [0001] The invention relates to a simulation device capable of simulating the environmental conditions of the digestive tract of broilers and the processes of digestion and absorption of feed nutrients under in vitro conditions, which can be used to study the digestion and absorption process of feed nutrients in the digestive tract of broilers and the evaluation of potency It can also be used to evaluate the stability and biological potency of biological feed additives in the digestive tract of broilers. technical background [0002] With the continuous and in-depth research on the digestive physiology of monogastric animals, the development of modern science and technology and the commercial production of various animal digestive enzymes, the in vitro digestion simulation technology of monogastric animals has also been greatly developed, especially the in vitro digestion simulation of pigs. There are many technical research reports and standardized operating...

AI Technical Summary

Problems solved by technology

Assembled with Gauther et al. (1982) using standard spare parts, but the composition is more complicated

The pig small intestine digestion simulation device given by Savoie et al. (1986) reduces the volume of the reaction solution and reduces the consumption of reagents, but there is still the problem that the digested chyme is at the bottom of the inner cylinder and the dialysis efficiency of the dialysis bag is low.

[0005] The above two small intestine digestion simulation devices are based on the parameters in the pig's digestive tract, and the specifications of each component of the device are further determined, especially the size of the inner and outer tubes used for dialysis of digestible nutrients on the in vitro digestibility. Large impact, not suitable for simulating the digestion and absorption of nutrients in chickens
