Abstract

The invention discloses an application of antrodia camphorata polysaccharide in preparation of an anti-LPS stress feed for yellow feather broilers. The action mechanism of the antrodia camphorata polysaccharide in resisting oxidation and improving intestinal health and growth performance is researched, the application of the antrodia camphorata polysaccharide is widened, and a foundation is laid for the application of the antrodia camphorata polysaccharide in the breeding industry.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, and more specifically relates to the application of antrodia camphorata polysaccharide in preparing anti-LPS stress feed for yellow-feathered broilers. Background technique [0002] Under normal physiological conditions, broiler body oxidation and anti-oxidation are often in a dynamic balance, but many exogenous or endogenous stimuli can cause the body to be in a state of oxidative stress, which has a serious impact on the healthy breeding of broiler chickens. The intestine is the most important digestive organ in animals, and it is also the first organ to suffer oxidative damage. Pathogenic Escherichia coli can destroy the intestinal microbial barrier, damage the intestinal mucosal structure of chickens, cause oxidative stress, and affect the intestinal tract healthy. At the same time, in the process of external pathogenic microorganism infection, the liver is the main organ for removi...
