Buffalo feed based on amino acid metal ion chelate and application of buffalo feed

The invention relates to the technical field of feed processing, in particular to buffalo feed based on amino acid metal ion chelate and application of the buffalo feed, and mainly researches chelates of different combinations of lysine, isoleucine, methionine and/or alanine and zinc ions, copper ions and/or selenium ions. It is found that part of the chelate has a relatively strong synergistic effect on sugarcane tail leaf feed and can play roles in promoting the growth of the buffalo and improving the immunity of the buffalo, moreover, it is found that the mixed use of the Lys-Ile-Met-Zn chelate, the Lys-Ile-Cu chelate and the Lys-Ile-Met-Ala-Se chelates achieves an obvious synergistic effect on the immunity of the buffalo. The optimal addition amounts in the basic ration of the sugarcane tail leaves are 0.5%, 0.5% and 1%. The application range of the amino acid chelated metal salt in the buffalo feed is further widened through the research of the application, and the application of the sugarcane tail leaf
