摘　　要：秸秆是反刍动物重要的粗饲料来源,但秸秆中纤维素和木质素含量较高,导致秸秆饲料的利用率相对较低。秸秆经过膨化处理后,其中部分纤维分离呈丝状,使秸秆表面粗糙,有利于微生物附着、繁殖,能够更好地发挥微生物降解功能,进而提高饲料品质和饲料养分转化率。文章综述了膨化和生物发酵对秸秆的作用效果及其在反刍动物生产中的应用,以期为膨化秸秆发酵饲料在动物生产中的进一步应用提供参考。Straw is an important source of roughage for ruminants,but the high content of cellulose and lignin content in straw results in the low utilization rate of straw feed relatively.After the straw is puffed,some of the fibers are separated into filaments,which makes the straw surface rough,conducive to microbial adhesion and reproduction,can better play the microbial degradation function,and then improve the feed quality and feed nutrient conversion rate.The paper reviews the effects of extruded straw and biological fermentation on straw and their application in ruminant production,in order to provide reference for further application of extruded straw fermented feed in animal production.
