摘　　要：本试验用从禾本科牧草上分离得到的植物乳杆菌和蒙氏肠球菌作为青贮添加剂调制田间中等规模的无芒雀麦青贮,研究其对西门塔尔牛生产性能的影响。选用经产健康的西门塔尔牛10头,采用随机分组试验设计,分为2个处理组,每组5头牛,分别饲喂含干草和青贮料的日粮,精粗比30∶70。试验期为17d。预饲期12d,正试期5d。结果表明,同饲喂干草组相比,给西门塔尔牛饲喂添加植物乳杆菌和蒙氏肠球菌的无芒雀麦青贮料,可以显著增加试验牛干物质采食量(DMI)(P<0.05),干物质消化率(DMD)提高了4个百分点(0.05<P<0.1),提高乳产量(P>0.05)及乳脂肪(P<0.05),对乳糖、乳蛋白及酪蛋白含量无显著影响(P>0.05)。To investagate the effect of Bromus inermis silage applying with Lactobacillus Plantrum and Enterococcus Munditii on the performance of Simmental cows, 10 multiparous cows were randomly divided into 2 treatments,and were fed with hay and actic acid bacteria silage respectively.The period was 17 d.The ratio of concentration to forage was 30：70. As a result, supplement Bromus inermis silage in diets could increase dry matter intake （DMI） evidently （P 〈 0.05 ）compared with hay, and the dry matter digestibility was increased by 4 percentage （P 〈 0.1 ）, milk yield （P 〉 0.05）and milk fat content increased （P 〈 0.05）, but there were no obviously change on lactoprotein,lactose and casein （P 〉 0.05 ）.
