[目的]探究复方中草药添加剂对奶山羊泌乳性能和乳成分的影响。[方法]挑选40 只2 岁龄健康无病、胎次相近的奶山羊,随机分为4 组,设置为对照组、复方中草药低剂量组、复方中草药中剂量组和复方中草药高剂量组,每组2 个重复,每个重复5 只,分别饲喂基础日粮+0 g/（d·只）、5 g/（d·只）、10 g/（d·只）和15 g/（d·只）的复方中草药添加剂,试验为期30 d。[结果]随复方中草药添加剂量的升高,奶山羊的采食量和奶料比有增加趋势（P>0.05）。与对照组相比,复方中草药中剂量组和复方中草药高剂量组奶山羊的产奶量显著增加（P<0.05）,分别增加6.86%和8.73%。与对照组相比,复方中草药中剂量组和复方中草药高剂量组的乳脂率和乳蛋白率显著升高（P<0.05）,分别升高4.09%、5.18%和3.35%、4.83%;各试验组山羊乳的乳糖率和乳干物质有增加趋势（P>0.05）。[结论]在日粮中添加复方中草药添加剂能有效提高奶山羊的泌乳性能,改善乳成分品质,且在本试验条件下,复方中草药添加剂量为15 g/（d·只）时效果最佳。

[Objective] To investigate the effects of compound Chinese herbal additives on lactation performance and milk composition of dairy goats. [Method] 40 healthy and disease-free dairy goats of 2 years old with similar parity were selected and randomly divided into 4 groups,which were set as the control group,the low-dose compound Chinese herbal medicine group,the medium-dose compound Chinese herbal medicine group and the high-dose compound Chinese herbal medicine group. There were 2 replicates in each group,and 5 goats in each replicate.The basic diet+0 g/（d·goat）,basic diet+10 g/（d·goat） and basic diet+15 g/（d· animal） of the compound Chinese herbal medicine additives were respectively fed, and the experiment lasted for 30 days. [Result] With the increase of the addition dosage of compound Chinese herbal medicines,the feed intake and milk-to-feed ratio of dairy goats tended to increase（P>0.05）.Compared with the control group,the milk production of dairy goats in the medium-dose and high-dose compound Chinese herbal medicine groups increased significantly（P<0.05）,increasing by 6.86% and 8.73%,respectively. Compared with the control group,the milk fat rate and milk protein rate of medium-dose and high-dose compound Chinese herbal medicine groups were significantly increased（P<0.05）,increasing by 4.09%,5.18% and 3.35%,4.83% respectively. The lactose rate and dry milk matter of dairy goat milk in each experimental group showed an increasing trend（P>0.05）. [Conclusion] Adding compound Chinese herbal additives to the diets could effectively improve the lactation performance of dairy goats and the quality of milk components,and under the conditions of this experiment,the best effect was achieved when the addition dose of compound Chinese herbal was 15 g/（d·goat）.
