China is rich in mulberry resources with strong ecological adaptability.The surplus mulberry leaves,low value mulberry branches,mulberry dregs and other resources in silkworm rearing production are rich in protein and a variety of bioactive substances.These things can not only provide sufficient nutrition for animal growth,but also help to provide a safety barrier for animal disease prevention.It is an ideal non grain feed resource.Under the situation of soaring global food and feed prices,the feed application of mulberry resources can alleviate the contradiction between people and livestock for food.Therefore,this paper summarized the key technologies and industrial applications of mulberry leaves,branches and mulberry dregs in feed application,and looked forward to the future trends.It provided reference for the development of high-quality mulberry resource feed.
