Abstract:

With the implementation of the strategy of "reducing antimicrobials, banning antimicrobials, and making products antimicrobial-free" in China's aquaculture industry, the use of plant extracts as feed additives has become an important research direction. Glycyrrhiza polysaccharide is a kind of plant polysaccharide extracted from licorice, and the extraction methods include solvent extraction, ultrasound-assisted extraction, and microwave-assisted extraction, etc. As natural biomolecules, Glycyrrhiza polysaccharides consist of monosaccharides such as arabinose, glucose, galactose, rhamnose, mannose, xylose, etc., which have a variety of biological activities such as antioxidant, anti-inflammatory, immunomodulatory, anti-tumor and so on. It has a significant role in protecting the health of animals. The addition of Glycyrrhiza polysaccharide to animal diets can improve body weight growth rate, feed utilization, and meat quality, in addition reducing the negative effects on animals caused by intestinal diseases and stress. Due to its anti-inflammatory and antioxidant effects, Glycyrrhiza polysaccharide effectively reduces inflammation and damage induced by disease and stress in animals. In this paper, the extraction methods, biological activities, and mechanisms of action of Glycyrrhiza polysaccharides were reviewed, their applications in animal production were also discussed, in order to provide a scientific basis for the application of Glycyrrhiza polysaccharides in animal breeding.

Key words: Glycyrrhiza polysaccharide, biological activity, mechanism, animal production
