The random area design was adopted in this experiment. Fresh Alfalfa and Dried Alfalfa took as material, the water content were 80% and 60% respectively. The effect of adding 4 kinds of different lactobacillus additives, 1 kind of enzyme preparation, 1 kind of lactobacillus and cellulose enzyme admixture on Alfalfa silage quality was studied. Again these 7 kinds of silages were assessed to adopt In Vitro Gas Production Method.The result show:1) Adding biological agents to the fresh alfalfa grass, the OM content of silages were higher than the raw material(p<0.01), the CP content of silages were lower than the raw material(0.01 |
