摘　　要：选择20头荷斯坦高产牛,采用配对分组设计分为对照组和试验组,每组各10头。对照组使用原日粮,试验组产前21d每天在日粮中添加繁奶康125g,于分娩当天添加量增至300g直到试验结束,以探讨日粮添加繁奶康对奶牛泌乳早期产奶性能(产奶量及乳品质)的影响。结果表明,补充繁奶康,产奶量、乳脂校正乳产量试验组明显高于对照组(P<0.05);奶牛采食量、乳脂率、乳蛋白率、乳糖率及乳干物质含量两组间差异不显著(P>0.05)。血液指标谷草转氨酶、谷丙转氨酶活性两组间无显著差异(P>0.05),高产奶牛补充繁奶康对泌乳早期产奶性能有较好的改善作用。An experiment was conducted to determine the effect of Bergaplus-D on milk yield and milk quality and blood biochemical Indicators in early lactation dairy cows.Twenty Holstein dairy cows were assigned equally to a control and an experimental group according to matched-pair grouping design.Dairy cows in the control group were fed raw diet.Dairy cows in the experimental group were fed total mixed ration supplemented with 125g Bergaplus-D every day during 21 days before parturition.Dairy cows in the experimental group were fed raw diet supplemented with 300g Bergaplus-D during day after partum.The results showed that milk yield,FCM yield were increased（P〈0.05） by Bergaplus-D supplementation;The concentrations of milk fat,milk protein,milk sugar,milk dry matter,and feed intake were not affected（P〉0.05） in early lactation dairy cows supplemented with Bergaplus-D compared with the controls.AST and ALT were not affected（P〉0.05） by Bergaplus-D supplementation.The results indicated that Bergaplus-D had a perfect improvement on milk performance in early lactation dairy cows.
