Xylo-oligosaccharide(XOS)is functional oligosaccharides with prebiotic activity,mainly derived from lignocellulosic materials,such as rice husk,corn cob,straw,wheat bran and other agricultural products.XOS plays an important role in immune regulation,lowering blood lipids and regulating intestinal flora,and has become one of the functional oligosaccharides that have attracted much attention at home and abroad.In this paper,the structure,physical and chemical properties and physiological functions of XOS are systematically summarized,and the application progress of XOS in animal husbandry production is discussed,in order to pro-vide theoretical basis for the development and utilization of XOS in animal husbandry production.[Chinese Journal of Animal Nutrition,2023,35(12):7625-7632]
