Physiological Functions of Glycyrrhiza Polysaccharides and Its Applications in Livestock and Poultry Production
With the implementation of the strategy of"reducing antimicrobials,banning antimi-crobials,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 polysac-charide is a kind of plant polysaccharide extracted from licorice,and the extraction methods in-clude solvent extraction,ultrasound-assisted extraction,and microwave-assisted extraction,etc.As natural biomolecules,Glycyrrhiza polysaccharides consist of monosaccharides such as arabi-nose,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 polysaccha-ride 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 in-flammation 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 re-viewed,their applications in animal production were also discussed,in order to provide a scientif-ic basis for the application of Glycyrrhiza polysaccharides in animal breeding.
