【摘要】 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、母羔羊二月龄断奶平均体重分别为15.21 kg、13.39 kg,六月龄公、母羊体重达到30.74 kg、24.62 kg;周岁公、母羊体重分别为48.55 kg、37.24 kg;成年公、母羊体重分别为73.92 kg、50.26 kg。简阳大耳羊二月龄断奶,到六月龄公、母羊平均日增重分别为129.42 g和93.58 g。简阳大耳羊生长发育曲线表明,简阳大耳羊断奶至八月龄的体重呈直线上升趋势,八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基本特征。更多还原

【Abstract】 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 month age; it reached 30.74 kg and 24.62 kg at the 6 month age, 48.55 kg and 37.24 kg at the 12 month age, 73.92 kg and 50.26 kg at adult age, respectively. The average daily gain(ADG) was 129.42 g and 93.58 g from weaning to 6 month age for male and female, respectively. The growth curve of Jianyang Daer goat showed that the weight was linear increased from weaning to 8 month age, then slowdown after 8 month age.更多还原
