摘  要:
为了探索昌台牦牛种质资源特性,详细了解昌台牦牛的生长发育性能,试验采用对昌台牦牛各个年龄组牛只的体尺体重进行测定。结果表明:公、母昌台牦牛的初生重分别为(12.44±2.53)kg、(11.67±1.75)kg,1.5岁、2.5岁、3.5岁、4.5岁及成年公牦牛的体重分别为99.90 kg、101.65 kg、216.10 kg、220.16 kg、355.97 kg,母牦牛分别为101.65 kg、162.34 kg、194.00 kg、192.95 kg、252.61 kg。昌台牦牛生长发育在3.5岁之前相对较快,3.5~4.5岁增长较为平缓,与其他牦牛的生长发育性能相一致。

摘  要:
To explore the characteristics of germplasm resources of Changtai yaks and understand in detail their growth and development performance,the body size and weight of the yaks from all age groups were determined in the test. The results showed that the birth weight of male and female yaks was( 12. 44 ± 2. 53) kg and( 11. 67 ± 1. 75) kg,respectively; the body weight of male yaks at 1. 5,2. 5,3. 5,and 4. 5 years of age and adult yaks was 99. 90 kg,101. 65 kg,216. 10 kg,220. 16 kg and 355. 97 kg,respectively; and the body weight of female yaks at1. 5,2. 5,3. 5,and 4. 5 years of age and adult yaks was 101. 65 kg,162. 34 kg,194. 00 kg,192. 95 kg and 252. 61 kg,respectively. The results indicate that the growth and development of Changtai yaks is relatively fast before at 3. 5 years of age,and the growth is relatively gentle at 3. 5 to 4. 5 years of age,which is consistent with the growth and development performance of other yaks.
