摘要
以引进的德国美利奴种羊及其繁殖后代为对象,观测其生长繁育特性。结果表明:德国美利奴羊的初生重、1、3、6月龄和周岁体重分别为4.20±0.73kg、12.96±3.33 kg、27.30±5.50 kg、40.65±5.50 kg、69.27±6.22 kg;1、3、6月龄的平均日增重依次为321±78g、264±54g、223±22g。初产母羊产羔率、繁育率分别为:129.63%、114.81%,经产母羊产羔率、繁育率分别为157.00%、151.00%。结果表明,对于早熟、生长速度快的德国美利奴羊,给予充足的营养,可保证其遗传潜力得以充分发挥,与本地羊杂交,表现出良好的杂种优势。
The experiment was aimed to observe growth performance and reproductive performance of Germany Merino Sheep as well as descendants in E＇Min county,Xinjiang.
