Abstract: The kinds and nutritional components of the algae which available in livestock and poultry production were summarized in this paper.The effects of algae-containing feed on the growth,immunity,meat quality,egg-laying performance and egg quality of livestock and poultry which represented by pig and chicken were emphatically introduced.The problems existing in the application of algae in livestock and poultry and some suggestions were pointed out to provide reference for the wide application of algae resources in pig and chicken production.Algae are widely distributed,easy to grow and high-yielding,especially the marine algae,which contain bioactive substances and nutrients that terrestrial plants do not possess.Microalgae which is rich in unsaturated fatty acids and pigments adding to the feed could improve the meat and egg quality of breeding animals.Macroalgae which is rich in polysaccharides and other bioactive substances adding to feed could improve the immunity of livestock and poultry.Adding a small amount of algae in feed could improve the feed stability,growth performance and feed utilization of livestock and poultry.Because of its anti-nutritional factors,excessive addition of algae to the feed will have a negative impact on livestock and poultry,but some anti-nutritional factors could be eliminated by proper pretreatment and the negative effects can be alleviated.
