Abstract:

As a potential immuno regulatory adjuvant,β-1,3/1,6-glucans are commonly found in fungi,yeasts and seaweeds.It consists of a linear skeleton of the β-1,3 key chain as main backbone and a highly branched β-1,6 bond as a side chain.Due to its special molecular bonding and intramolecular hydrogen bonding, it forms a spiral molecular structure.This unique configuration is easily accepted by the immune system and exerts its immunity features.β-1,3/1,6 glucan is the first one that has been found to be immunologically active dextran,creating a new chapter in the application of dextran as an immune enhancer.Studies have shown that β-1,3/1,6-glucan,as a biological immunomo regulatory adjuvant,has a regulatory effect on immune system and the efficiency of vaccination.It has higher biological activity,lower caloric value and other aspects, which can be widely used in the fields of medicine, health food and animal husbandry as a fat substitutes, functional factors and dietary fiber making it a worthy endeavor to research and develop as a functional feed additive.Based on the origin,mechanism and biological activity of β-1,3/1,6-glucan,the production performance and immune function of livestock and poultry was summarized in this paper,and the usage in livestock and poultry diets was analyzed hoping to provide fundamental basis for the application of β-1,3/1,6-glucan in diets of livestock and poultry.

Key words: β-1,3/1,6-glucan; biological activity; application effects
