摘　　要：本试验选用24头体重、年龄、胎次相近的3月龄波黄杂交山羊，研究以稻草为粗料饲喂条件下，补充不同营养水平精料对圈养山羊生产性能的影响。供试山羊随机分为3个处理组，每组8头。分别饲喂不同营养水平的精料日粮并配合稻草后，测定各组山羊的平均日增重和料重比。结果表明：在3—4月龄，精料3组山羊的日增重最高，分别比精料1组和精料2组提高61．5％（P〈0．01）、28．0％（P〈0．05）；精料2组日增重比精料1组提高26．2％，但差异不显著（P〉0．05）。料重比以精料3组最低。在5—6月龄，精料2和精料3组山羊日增重最高，分别比精料1组高49．8％、9．2％（P〈0．05）；精料2和精料3组间差异不显著。料重比以精料2组最低。To investigate the effect of concentrate supplement at different nutrition levels on the performance of goats, twenty - four three - month old goats hybridized from Boer Goats and Nan Jiang Yellow Goats were divided randomly into three treatments （group Ⅰ , group Ⅱ and group Ⅲ）. Each group had eight goats. All the goats had similar weight, age and type. The goats from different groups were fed with concentrate at different nutritional levels and straw to inspect their average daily gain and ratio of material to meat. The result were as follows ： at the age of 3 - 4 month, ADG of group m was the highest,higher than those of group Ⅰ and group Ⅱ by 61.5 % （ P 〈 0.01 ） and 28.0% （ P 〈 0.05 ） , respectively. But the ADG of group Ⅱ was higher than that of group Ⅰ by 26.2% （ P 〉 0.05）. F/G in group m was the lowest. At the age of 5 - 6 month, there was no significant difference in ADG between group Ⅱ and groupm ,but higher than that of group Ⅰ by 49.8% and 9.2% （P 〈 0.05） , respectively. F/G in group Ⅱ was the lowest.
