Abstract: Wolfberry polysaccharides （lycium barbarum polysaccharide, LBP） is an important active ingredient in wolfberry, and is a water-soluble polysaccharide which includes six monosaccharide like Ara, Clc, Gal, Man, Xyl and Rha. LBP is rich in trace elements and amino acids, and has some functions of enhancing immunity, anti-cancer, lowering blood pressure, anti-thrombotic and anti-aging effects. Therefore, as a new type of green feed additives in animal production, LBP has good prospect in animal production. The physiological function and role in animal production of LBP were summarized.
