| 摘 要： | 为探讨不同微生物制剂对玉米青贮饲料品质的影响，以高水分春玉米秸秆为原料，进行乳酸菌和纤维素酶不同添加剂量的青贮饲料发酵试验。结果表明：玉米秸秆青贮过程中添加乳酸菌和纤维素酶，可有效降低青贮饲料腐败率、改善和提高青贮饲料的品质及营养价值，其中以添加0．30％纤维素酶的效果最佳，腐败率低于1．4％、粗蛋白含量3．49％、氨态氮与总氮质量比m（VBN），m（TN）]为6．60、丁酸含量为0、中性洗涤纤维含量11．48％、酸性洗涤纤维含量7．02％、酸性木质素含量1．42％。可见，筛选和添加适宜适量的微生物制剂是提高青贮饲料品质的有效途径。

| Abstract: | In order to know about the effects of different microbial preparations on the quality of corn straw silage, high-moisture content of spring corn straw was used as raw materials to carry out fermentation of silage by adding different percentages of Lactobcillus and cellulase. The results showed that during the fermentation process of corn silage, adding Lactobcillus and cellulase could effectively decrease the decay rate of silage, improve and increase the quality and nutrient value of silage, and the effect... |
