摘　　要：菌酶协同发酵能提高饲料原料中纤维物质和抗营养因子的降解效率,改善发酵品质,提升适口性,对畜禽生长和肠道健康发挥积极作用。本文介绍了植物纤维的降解机制以及真菌和细菌生产的纤维降解酶类型,总结了菌酶协同发酵饲料在动物生产中的应用效果,以期为深入研究菌酶协同作用机制提供参考。The synergistic fermentation of bacteria and enzymes can increase the degradation efficiency of fiber and antinutritional factors in feed ingredients,improve fermentation quality and palatability,and play a positive role in the growth and intestinal health of livestock and poultry.This review introduced the degradation mechanism of plant fiber and the types of fiberdegrading enzymes produced by fungi and bacteria,and summarized the application effects of synergistic fermented feeds of bacteria and enzymes in animal production,in order to provide reference for further exploring the synergistic fermentation mechanism of bacteria and enzymes.
