目前，我国饲料工业发展迅速，然而国内饲料原料供应日趋紧张，优质蛋白质缺乏，每年需耗巨资进口大量氨基酸、鱼粉和豆粕等原料。为此，我们进行了复合氨基酸添加剂的研究，其目的是为饲料工业和养殖业提供大量的优质蛋白质原料，解决我国饲料资源短缺的问题。　　我们从1999 At present, China’s feed industry is developing rapidly. However, the domestic supply of feed raw materials is increasingly tense and high-quality protein is scarce. Large amounts of amino acids, fish meal and soybean meal are required to be imported each year. To this end, we conducted a study of composite amino acid additives, the purpose of which is to provide a large number of high-quality protein raw materials for the feed industry and aquaculture to solve the problem of shortage of feed resources in our country.
