添加乳酸菌和纤维素酶对苜蓿青贮品质的影响
The effects of adding lactic acid bacteria and cellulase on alfalfa silage quality
摘要
Abstract
Alfalfa in initial flowering stage was harvested and wilted for 0, 8, or 32 hours 27.15%, 38.45%, and 50.87%, respectively）, and was ensiled with lactic acid bacteria of 10s cfu/g＋0.1 g/kg, 106 cfu/g＋0.05 g/kg and 107 cfu/g＋0. 025 g/kg. This study in fa （DM 50.87%） without additives had lower ammonia nitrogen content, conserved m produced more lactic acid. The addition of lactic （DM content was q-enzyme at rates dicated that alfal- ore DM, CP and acid bacteria and enzyme greatly improved alfalfa silage fermentation. Alfalfa （DM 38.45%） ensiled with lactic acid bact in reduction of ammonia nitrogen content and increases of CP and falfa （DM 38.45%） with the addi.tion of 104 cfu/g lactic acid ba than other treats. eria ＋enzyme performed well, resulting more lactic acid. The cteria and 0.05 g/kg silage quality of al- enzyme was better关键词
