中草药添加剂对奶牛抗热应激和产奶量的影响

The Effect of Chinese Herbal Medcine on Heat Stress and Milk Yield in Cow

本试验通过采取完全随机试验设计，选取20头中国荷斯坦奶牛，随机分为2组，即对照组（A组）和试验组（B组），研究中草药添加剂对奶牛抗热应激和产奶量的影响。结果表明：B组的4．0％标准乳量、矫正体重后的产乳量均高于A组，差异极显著（P〈0．01），说明使用奶牛抗热应激中草药添加剂可明显增强奶牛抗热应激能力，提高奶产量。

In this experiment, complete randomized design is adopted, 20 Chinese holstein cows were selected, and randomly divided into two groups：the control group （group A） and test group （group B）, to study the effect of Chinese Herbal Medicine additive on heat stress and milk production in dairy cows. Results showed that, in the group B 4.0% standard milk volume and the amount of milk after correct weight were higher than group A, and the difference were extremely significant （P〈0.01）, using Chinese Herbal Medicine additive could obviously enhance the ability of resisting heat stress in dairy cattle, and increase milk production.
