在早期断奶仔猪饲料中添加酶制剂,既能改善饲料利用率和提高仔猪生产性能,且无毒、无副作用、无残留。本文综述了国内外饲用酶制剂的种类和作用机理,在仔猪饲料中如何选择饲用酶制剂。列举了近年来,国内外对于饲用酶制剂应用于仔猪日粮的实验研究与成果,为今后进一步研究饲用酶制剂在断奶仔猪日粮中的应用提供参考。 In the early weaning piglet feed enzyme preparation, both to improve feed utilization and improve piglet performance, and non-toxic, no side effects, no residue. This article reviews the types and mechanism of feed enzymes at home and abroad, and how to choose feed enzymes in the feed of piglets. In recent years, the domestic and foreign research on the application of feed enzyme preparation to piglet diets are listed, which will provide references for further study on the application of feed enzyme in weaning piglet diets.
