Abstract: As one of the main source of nutrition of feed livestock and poultry,quality of protein takes a major effect on normal growth and reproduction of them. Compound feed containing animal-brone proteins with the balance of amino acid content can satisfy the need of growth and reproduction of livestock. Nowadays,animal-brone proteins in compound feed mainly originate from fish meal,bone meal,blood meal and feather powder,but they still can′t meet the need of development of feed industrial. Therefore,utilizing and expanding animal-brone proteins is helpful for the development of feed industry and livestock industry.
