中草药添加剂对热应激奶牛生产性能及生理指标的影响

Effects of Chinese Herbal Drugs as Additives on Yield Performance and Physiological Parameters of Heat Stress Cow

将年龄、胎次、生产性能相近的8头娟姗奶牛随机均分为对照组和试验组,试验组牛在TMR饲料中添加抗热应激中草药添加剂,对照组牛不添加。分别测定两组奶牛的采食量、产奶量、呼吸、直肠温度等指标。研究表明:抗热应激中草药添加剂能够提高奶牛采食量10.77%,提高产奶量8.96%,而呼吸频率、直肠体温均出现下降。

8 milk cows, which had the same time of life, parity and milk yield performance, were randomly divided into trials group and control group. Trials group was fed the TMR mixed by the Chinese herbal drugs as additives; the control group was fed the same TMR without additives, and then measured the account of feed intake, milk yield, rates of respiratory, rectal temperature. According to this experiment, the account of feed intake increased by 10.77 %, milk yield increased by 8.96 %, rates of respiratory and rectum temperature had both decreased.
