本研究以简阳大耳羊四世代核心群为试验素材．对简阳大耳羊生长发育规律进行了分析。结果表明：简阳大耳羊个体大、生长发育快，在舍饲条件下，公、母羔羊2月龄断奶平均体重分别为15．21奴、13．39kg，6月龄公、母羊体重达到30．74kg、24．62kg，周岁公、母羊体重分别为48．55kg、37．24kg，成年公、母羊体重分别为73．92奴、50．26kg；简阳大耳羊2月龄断奶，到6月龄公、母羊平均日增重分别为129．42g和93．58g：简阳大耳羊生长发育曲线表明，从断奶至8月龄其体重呈直线上升趋势，8月龄开始生长速度减缓．说明简阳大耳羊具有早期生长快的特点。

An experiment was conducted with fourth generation of Jianyang Daer goat to study the growth,development law. The results showed that Jianyang Daer goat was a big-size goat with fast growing. The weaning weight of kids was 15.21 kg for male and 13.39 kg for female at the 2 months age, it reached 30.74kg and 24.62kg at the 6 months age, 48.55kg and 37.24kg at the 12 months age, 73.92kg and 50.26kg at the adult age respectively. The average daily gain （ADG） was 129.42g and 93.58 g from weaning to 6 months age for male and female, respectively. The growth curve of Jianyang Daer goat showed that the weight increased linearly from weaning to 8 months age, then slowed down after 8 month age, it proved that Jianyang daer goat had the characteristic of fast growing at early age.
