Cow silage leavening agent and application thereof

The invention discloses a cow silage leavening agent, and relates to the technical field of animal feed. The cow silage leavening agent comprises the following raw materials in parts by weight: 25-40 parts of microbial powder, 5-10 parts of an enzyme preparation and 25-30 parts of a compound additive; the microbial powder comprises bacillus amyloliquefaciens bacterial powder, bacillus cereus bacterial powder and bacillus coagulans bacterial powder according to the mass ratio of (1-2): (1-2): (3-6). The cow silage leavening agent can significantly reduce the content of cellulose in silage, significantly increases the content of nutrient substances such as crude protein and crude fat, and has the advantages of small color change compared with that before silage, soft texture, good palatability, short fermentation period and low cost. 本发明公开了一种奶牛青贮饲料发酵剂，涉及动物饲料技术领域。奶牛青贮饲料发酵剂包括以下重量份的原料：微生物菌粉25～40份、酶制剂5～10份和复合助剂25～30份；所述微生物菌粉包括解淀粉芽孢杆菌菌粉、蜡状芽孢杆菌菌粉和凝结芽胞杆菌菌粉，且其质量比为1～2：1～2：3～6。本发明的奶牛青贮饲料发酵剂可显著降低青贮饲料中纤维素的含量，显著增加了粗蛋白和粗脂肪等营
