Immune polysaccharide intensifier and preparation method and application thereof

Abstract

The invention relates to an immune polysaccharide intensifier, and the components of the intensifier and the mass percentages are as follows: 1-40 percent of beta-glucan, 1-40 percent of mannan-oligosaccharide, 1-40 percent of immune regulate factor, and 1-40 percent of poly-isomaltose. The intensifier can increase the resistance to pathogenic microbes and nonspecific defense mechanism of aquaculture animals, has high safety, small effect on environmental pollution, no residue, growth-promoting capacity, convenient use and low cost and is the immune polysaccharide intensifier which can improve physique of the aquaculture animals effectively.

Description

technical field [0001] The invention belongs to the field of veterinary medicine, in particular to an immune polysaccharide enhancer and its preparation method and application. Background technique [0002] While the aquaculture industry is developing vigorously in the world, due to reasons such as high-density intensive farming and excessive feeding, the environment has deteriorated, resulting in frequent occurrence of various bacterial diseases and viral diseases, which seriously hindered the sustainable development of the aquaculture industry. healthy growth. Fish, shellfish, shrimps, and crabs have all died on a large scale, especially the mortality rate of certain viral diseases is as high as 60% to 100%, which has caused a devastating blow to the aquaculture industry. At present, there are three main methods to control aquatic animal diseases: chemical treatment, vaccination and immune stimulation. Chemotherapy is mainly based on antibiotics and other chemical drugs ...
