| 摘 要： | 将３３头泌乳中期荷斯坦奶牛随机分为３组，试验Ⅰ组日粮中添加１．２ｍｇ／ｋｇ的Ｆ８９，试验Ⅱ组日粮中添加２０ｍｇ／ｋｇ的瘤胃素，结果表明：在热应激条件下，Ｆ８９可以提高奶牛的粗饲料采量和减缓产奶量下降；使用瘤胃素，奶牛产奶量比试前提高８．３２％；同时这两种物质都具有抗热应激和提高血清ＰＲＬ及Ｔ４水平的趋势。 |

| Abstract: | Holstein cows were divided into 3 groups at random to carry out a feeding trial. 1.2 mg/kg F89 and 20 mg/kg rumensin were added to the feed for experimental group 1 and experimental group 2 respectively. After 45 days, the experiment results show that F89 can increase the roughage intake and keep the milk yields stable; rumensin can increase the milk yields by 8.32% compared with that of the pre?trial and by 12.86% compared with that of the control group (group 3). These two chemicals can also increase the levels of serum PRL and T 4 and release the heat stress of dairy cows. |
