Abstract: In the past few decades,due to the abuse of feed antibiotics in animal husbandry,the normal intestinal flora of livestock and poultry has been destroyed and caused a series of problems such as intestinal bacterial resistance and environmental pollution,seriously damaged livestock and poultry intestinal health.At the same time,intensive farming has become the development direction of animal husbandry in recent years,and the scale of breeding is getting bigger and bigger.How to effectively improve the immunity of livestock and poultry has become the focus of research.A healthy intestinal tract is the basis for ensuring the healthy growth of livestock and poultry.Maintaining a healthy intestinal flora can effectively improve the immunity and disease resistance of the animal body.Mannan oligosaccharides is a new green feed additive.As a kind of functional oligosaccharide,it has the functions of improving intestinal health and improving immune response of livestock and poultry.In pig production,the addition of mannan oligosaccharides can improve the growth performance and immunity of weaned piglets.In poultry production,the addition of mannan oligosaccharides can improve the intestinal flora of poultry and improve production performance and meat quality.The article mainly introduces the structure and physicochemical properties of mannan oligosaccharides,improves intestinal health and immune regulation mechanism and its application in weaned piglets,finishing pigs,laying hens and broiler chickens.The paper summarizes the regulation mechanism and immune pathway of mannan oligosaccharides on intestinal health and immunity of livestock and poultry,and aims to provide theoretical basis for the in-depth study of manno oligosaccharides in intestinal health and immune regulation and its application in livestock and poultry breeding.

Key words: mannan oligosaccharide; immune regulation; intestinal health; mechanism; production performance
