Description

technical field

[0001] The invention belongs to the technical field of veterinary pharmaceutical preparations, and relates to the application of water-soluble yeast glucan in livestock and poultry, more specifically, the application of yeast glucan injection in improving the immune efficacy of milk cow foot-and-mouth disease vaccine. technical background

[0002] Yeast glucan is a pure natural active immune regulator extracted and refined from yeast, which can effectively activate macrophages and induce a series of immune responses in the body, thereby improving the body's immune function. In addition, dextran has the functions of scavenging free radicals, anti-radiation, anti-tumor, dissolving cholesterol, preventing hyperlipidemia and infection caused by viruses, fungi, bacteria, etc., so it is widely used in medicine, food, cosmetics, feed and other industries.

[0003] Yeast glucan extracted from yeast cell wall is insoluble in water. Adding water-insoluble yeast glucan ...
