微生物菌剂在不同饲料原料青贮过程中的应用
Application of Silage Microbial Agents in Different Silage Raw Materials
摘要
Abstract
Silage is an important feed source for ruminant animal and its yield and quality affect the development of animal husbandry.Due to the easy occurrence of aerobic spoilage in the silage process,which leads to feed safety issues,its use is restricted.To solve these issues,microbial additives were often used in silage.Bacteria that can be used as feed additives include Bacillus subtilis,Enterococcus,Lactobacillus,Yeast,Alcaligenes faecalis,Bifidobacterium,and so on.Bacillus subtilis mainly improve feed conversion rate by secreting cellulose extracellular enzymes to degrade cellulos;Homofermentative lactic bacteria such as Enterococcus and Lactobacillus plantarum lay a good foundation for later fer-mentation by reducing the pH in the early stage of fermentation;heterofermentative lactic bacteria such as Lactobacillus brucelli can improve the aerobic stability of silage feed;Yeast can inhibit the growth of mold in feed;Alcaligenes faeca-lis can enhance the efficiency of lignin degradation.This article reviewed the application status of above-mentioned strains in different silage materials,providing reference for the development of more effective feed silage methods.关键词
