本文主要探讨了中草药添加剂对不同泌乳阶段奶牛生产性能的影响。选择胎次相同、产奶量相近的健康荷斯坦牛24头,根据泌乳期的天数分为4个区组,每组以试验前后自身作为对照;将中草药添加剂按1%的比例添加到基础日粮中,饲喂28d。结果表明,除泌乳131～158d组外,其他各试验区组奶牛产奶量都有不同程度的提高,特别对泌乳237～277d的奶牛,其增奶效果最优,产奶量与试验前相比提高了4.3%（P〈0.05）,且乳房炎和蹄病的发病率为0。这表明中草药添加剂可提高泌乳奶牛产奶量,延缓中后期奶牛泌乳的下降趋势,并能对抗热应激,减少乳房炎的发病率,提高经济效益。

This experiment was conducted to investigate the effects of Chinese Herbal Medicine on production performance of dairy cattles in different Lactation periods.Parity,milk yield similar and health 24 Holstein cattle were divided into four groups according to the periods of lactation,using self-control before and after adding 1% Chinese herbal additives to the basal diet.The trial lasted 28 d.The results show that,Except the milk production quantity decline in lactation131~158 d of the cows,the milk production quantity have been improved to varying degrees of each experimental group,especially lactation 237-277d of the cows increased milk effect which the test significantly increased by 4.3%（P 0.05）compared to before,and the incidence of mastitis and hoof disease was 0.These results suggested that Chinese herbal medicine in the basic diet of lactating dairy cows can improve lactation milk yield,delay the downward trend in the late cows,confront the heat stress,reduce the incidence of mastitis,and improve the economic efficiency of production.
