摘要
选用２０头荷斯坦干乳母牛，随机分为４组，每组５头，研究饲喂抗氧化剂二氢吡啶或雄生素Ｅ对奶牛泌乳性能的影响。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。饲喂二氢吡啶或二氢吡啶＋维生素Ｅ可以显著提高奶牛的产奶量（Ｐ＜０．０５）。各组之间乳脂肪和乳蛋白含量差异不显著。
Twenty Holstein dry cows were used in a four factorial experiment to study the effect of added dietary antioxidants diludine and vitamin E on the lactation performance of the cows. The results showed that adding antioxidants doesn′ t affect the feed intake and milk composition . However, supplementing diludine alone or combined with vita - min E, the milk yield was significantly increased( P < 0. 05) , and the milk fat and pro- tein percentages were unaffected .
