摘　　要：[目的]为云南省奶山羊产业的发展提供参考。[方法]在初产萨能奶山羊日粮中添加低、中、高水平的精料,探讨不同精料水平对初产萨能奶山羊的生长及繁殖性能的影响。[结果]补饲中、高水平的精料后,初产萨能奶山羊的妊娠增重及产后失重均有一定程度提高,但其产羔率、羔羊初生重、产奶量和育成增重等繁殖性能均没有太大改善。[结论]综合考虑养殖成本及奶山羊后续生产,建议在生产中采用中营养水平精料对妊娠期和哺乳期的初产萨能奶山羊进行补饲。[Objective] The research aimed to provide references for the industrial development of dairy goats in Yunnan Province. [ Method ] The diet of primiparous Saanen Dairy Goats was supplemented with low, medium and high nutrition level of concentrates to discuss the effects of different nutrition level of concentrates on the growth and reproductive performance of primiparous Saanen Dairy Goats. [ Result] After supple- menting medium and high nutrition level of concentrates, the pregnant weight gain and postpartum weight loss of primiparous Saanen Dairy Goats were increased to different extent, but the lamb birth rate, lamb birth weight, milk yield, growing weigh gain and other reproduction perform- ances weren＇t significantly improved. [ Conclusion ] Considering the the breeding cost and the following production of dairy goats, it was suggested that medium nutrition level of concentrates should be supplemented in the diet of primiparous Saanen Dairy Goats during the pregnancy period and lactation period in the production.
