Abstract: Fucoidan is a natural heteropolysaccharide,it is rich in natural resources,safe and non-toxic,it has a variety of physiological functions.Fucoidan can remove excess free radicals in the body,activate the antioxidant enzyme system,inhibit the signal transduction of oxidative stress pathways to exert antioxidant function,improve the body's immunity by inhibiting the production of inflammatory factors in the body,inhibiting the inflammatory pathway,promoting antibody expression,and improving the body's non-specific immunity,promote the apoptosis of cancer cells,and inhibit angiogenesis and improve the body's immunity to play an anti-tumor effect.Fucoidan also has various biological functions such as bacteriostasis,anti-virus and anti-thrombosis.Animal experiment shows that fucoidan can reduce the feed-to-gain ratio of piglets and improve the digestibility of nutrients,increase the total feed intake,total weight gain and feed conversion rate of chicks,increase significantly the weight,growth rate and PER of wild pheasants in South Asia,increase chicken's weight and breast muscle weight,improve the antioxidant capacity of pork,reduce intestinal inflammation and edema,increase intestinal villi height,improve intestinal flora balance,and adjust glucose and lipid metabolism,reduce body fat content.This article reviews the physical and chemical properties,physiological functions,and application status of fucoidan in animal production,in order to provide a theoretical basis for the application of fucoidan in animal production.

Key words: fucoidan; antioxidant; immunity; antitumor; animal production
