摘　　要：瘤胃微生物在反刍动物饲料消化过程中起着至关重要的作用,其分泌的酶的数量和活性直接决定了瘤胃微生物对饲料中营养物质的分解、利用以及合成微生物蛋白的效率。动物品种、生理阶段、日粮组成、昼夜节律等均能对酶的活性产生影响。通过改变饲料精粗比、使用饲料添加剂、调节昼夜节律可以很好地调控酶的活性,提高饲料利用效率。文章对瘤胃微生物内源酶的种类和调控方法进行综述,旨在为深入探究瘤胃微生物内源酶提供参考。Rumen microorganisms are essential for the digestion of feed in ruminants.The quantity and activity of the enzymes they secrete directly influence the efficiency of nutrient breakdown,utilization,and microbial protein synthesis.Enzyme activity is affected by factors such as animal species,physi-ological stage,feed composition,and circadian rhythm.Manipulating concentrate to forage ratio,employ-ing various feed additives,and regulating circadian rhythms can effectively modulate enzyme activity and enhance feed efficiency.This article provides a review of the types of endogenous enzymes in ru-men microorganisms and their regulation meth-ods.The aim is to provide a reference for the regulation of endogenous enzyme activity in ru-men microorganisms.
