摘要
将24头荷斯坦奶牛随机分为 4 组,研究饲喂硒或维生素 E对奶牛泌乳性能的影响。对照组饲喂基础日粮,试验Ⅰ组在基础日粮中添加硒,试验Ⅱ组添加维生素E,试验Ⅲ组硒和维生素 E同时添加。结果表明,日粮中添加抗氧化剂不影响奶牛的干物质采食量(P>0 05)。饲喂硒或硒+维生素E可以显著提高奶牛的产奶量(P<0 05)。各组之间乳脂率、乳蛋白和乳糖含量的差异不显著(P>0 05)。
The results showed that the feed intakes of group Ⅰ,Ⅱ,Ⅲ and the control group were unaffected (P>0.05). However,supplementing Se along or combining it with vitamin E,the milk yield was significantly increased (P<0.05). and the milk fat and protein percentages were unaffected (P>0.05).
