Research Progress on Protective Effects of Chitosan Oligosaccharides on Intestinal Mucosal Barrier Function
Chitosan oligosaccharides are the only alkaline amino oligosaccharides that exist in large quantity in nature.Chitosan oligosaccharides have antioxidant,anti-inflammatory,antibacterial and other biological func-tions,and can be used as safe and effective feed additives in animal diets.At present,the research on chitosan oligosaccharides mainly focuses on the growth performance,antioxidant and immune function in livestock and poultry.In recent years,studies have shown that chitosan oligosaccharides also have protective effects on intes-tinal damage,so they have been widely concerned.This article reviewed the biological functions of chitosan ol-igosaccharides and their protective effects on intestinal mucosal barrier function,aiming to provide theoretical references for the application of chitosan oligosaccharides in livestock and poultry production.[Chinese Journal of Animal Nutrition,2024,36(11):6917-6928]
