Abstract: In recent years,the breeding industry had a rapidly development in our country.Then,the requirements of feed were also increased year by year accordingly.However,the production of grains used as feedstuff were not increased with a similar fold.It is the most challenge to treat the contradiction between fast developed breeding industry and less increased grain production.The yeast derived feedstuffs have great potential to be used as future feedstuff in large scale for the specialty of good palatability,rich in nutrition and functional regulation substances,nutrition comprehensive and cheap.Yeast derived feedstuffs contain live yeast,yeast culture,yeast hydrolysate,yeast cell wall and yeasts enrichment with trace elements.Most of studies on yeast derived feedstuffs showed it’s mainly function in breeding industry were growth and immunity enhancement in livestock and poultry and aquaculture industry.Here,we do our best to summarize the application and potential development of yeast derived feedstuffs.

Key words: yeast, feedstuff, breeding industry, growth enhancement, immunity
