| 摘 要： | 试验将96头荷斯坦牛,按年龄、胎次、泌乳天数、日产奶量相近的原则随机配对分成2组。试验组奶牛每头添加1g/d高活性干酵母,饲喂30d。结果表明：高活性干酵母对奶牛产奶量有所提高,但差异不显著（P〉0.05）;对乳脂肪率和乳蛋白率无显著影响（P〉0.05）;对尿素氮存在显著影响（P〈0.05）;乳中体细胞数有降低的趋势,但差异不显著（P〉0.05）。

| Abstract: | Ninty-six dairy cows with similar age, parity, lactation length,daily milk yields were selected,and randomly divided into 2 groups（testing group and control group）.Each dairy cow of treatment group was supplied 1 g/d yeast which has the high activity.The results indicated that, milk yield has exaltation, but have insignificant diference （P〉0.05）.No significant influence was found to the components of milk fat rate and milk albumen rate （P〉0.05）.Testing group MUN is significant diference （P〉0.05） than control group （P〈0.05）.SCC of milk is increment trend, but have insignificant diference （P〉0.05）. |
