摘　　要：为探索云南考摩型细毛羊的增重规律,选择体重20 kg左右的云南考摩型细毛羊22只,测定其体重。结果发现,随着云南考摩型细毛羊日龄的增加,其增重速度逐渐加快,采食量逐渐增大,牧草转化效率逐渐提高;在同一时期,绵羊日增重为公羊>羯羊>母羊,饲料转化效率公羊>羯羊>母羊。这一规律也分别在血清生化指标及激素含量中找到依据。In order to explore whether Yunnan Cormo sheep have genetic depression in the reproduction of the long-term degradation, 22 Yunnan Cormo fine-wool sheep were selected to determine its growth performance. The results showed that the weight gain, feed intake, forage conversion efficiency increased gradually with the age. The daily gains were ram〉 wether〉 ewe, the feed conversion efficiencyies were ram〉 wether〉ewe. This rules could be seen in the serum biochemical indices and hormone content also.
