摘　　要：本试验选取体重、胎次、泌乳阶段、产奶量基本相近的健康中国荷斯坦产奶牛26头,配对分成两组,即对照组和试验组,进行青贮皇竹草替代青贮玉米秸的饲喂试验。对照组按原日粮不变,试验组用5 kg青贮皇竹草替代10 kg青贮玉米秸。预试期7 d,正试期21 d。结果表明:试验组与对照组相比,日均产奶量相对提高0.73 kg,差异显著(P<0.05);乳蛋白相对提高0.05个百分点,乳脂率相对提高0.03个百分点,总固体物相对提高0.06个百分点,差异均不显著(P>0.05);从经济效益比较,试验组每头牛日均收益相对提高2.21元。Twenty--six Holstein cows were assigned to two group, which were similar to body weight, parity, laetation period , milk yield and so on. Control group fed original ration, and test group fed hybrid giant napier silage 5 kg substitute for corn stover silage 10 kg in original ration. It took 7 days to do a preliminary experiment, and the period of formal experiment was 21days. The results showed that the average daily milk yield of test group were 4.7 % higher than that of control group, milk fat has been raised 0. 030%, milk protein 0.05%, total solid substance 0.03%, respectively, From the point of view of economic benefits, the profit of test group has increased 2.21 yuan than that of control group.
