| 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。 |

| Abstract: | 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. |
| Keywords: | Yunnan Cormo fine-wool sheep weight gain |
