摘　　要：在春季和秋季,分别随机选择出生日龄相差10日内的南江黄羊羔羊120只,其中公羊60只、母羊60只,组成试验组和对照组,对其初生重和1、2、4和6月龄的体重及2、4和6月龄体尺进行测定。结果表明,南江黄羊快长系在舍饲条件下南江黄羊在早期随着年龄的增加而增重速度加快,2月龄前增重速度最快为第一生长高峰,断奶过渡期（3~4月龄）生长较慢,后备期（5~6月龄）增重恢复出现第二次生长高峰。在舍饲条件下,6月龄公羊体重达到32.97 kg、母羊26.84 kg,比南江黄羊新品种形成时分别提高20.33%和22.89%。100日龄羔羊的胴体重达到7.97 kg,6月龄羊的胴体重14.88 kg、屠宰率49.91%,比南江黄羊品种群的胴体重增加7.85 kg,屠宰率提高5.93个百分点。During the spring and autumn, respectively selected at random within lO days after birth age difference of 120 Nanjiang yellow goat lamb, including 60 RAMS and ewes 60, experimental group and control group, the birth weight and 1, 2, 4 and 6 months of age and weight 2, 4 and 6 months of age body measurements. Results show that the Nanjiang yellow goat fast long system under the condition of stabling the Nanjiang yellow goat in the early days with the increase of age and weight gain speed, two months ago to put on weight for the fastest growth of the first peak, weaning transition （3-4 months） grew more slowly, backup period （5-6 months） to put on weight recovery in the second growth peak. Old ram in June barn feeding conditions, weight is 32.97 kg, 26.84 kg, ewe than it did when the Nanjiang yellow goat new varieties increased by 20.33% and 20.33% respectively. 100 days of age lamb carcass weight is 7. 97 kg, 6 months sheep body weighs 14.88 kg, slaughter rate 49.91%, than the Nanjiang yellow goat species group increase 7.85 kg body weight, slaughter rate increased by 5.93%.
