青贮饲料添加剂应用的研究进展

摘要

青贮饲料因营养价值高、成本低且不受季节和气候的限制,广泛应用于反刍动物生产中；但其制作过程中涉及物质的降解、益生菌的发酵等过程,故在制作青贮饲料过程中常使用青贮添加剂.青贮添加剂对青贮饲料起防腐、促进发酵、提高适口性等作用.青贮添加剂按其作用可以分为:抑制性添加剂、促进性添加剂、营养性添加剂.作者综述了近几年来青贮饲料添加剂的种类、作用、应用效果及今后的发展方向.%Silage is widely used in ruminant production because of high nutritive value, low cost and not limited by the weather and season. During the process of making silage, there are refer to degradation, fermentation, so it is necessary to use additive to control these process. Silage additives play roles in silage preservation, promotion, improving the palatability in fermentation. Silage additives can be divided into inhibition additives, catalytic additives, nutritional additives. This article provides an overview for the kinds, function and its effect of silage additives in recent years, as well as the development direction in the future.
