摘要
对l/2野血牦牛和家牦牛的初牛犊牛和6月龄1/4野血犊牛进行了生长发育指标的测定和比较。测定结果表明:1/4野血初生牦犊牛体高、体斜长、胸围和体重比家牦牛初生犊增加1.80cm、3.42cm、2.28cm和1.27kg,分别提高了3.51%、7.33%、4.12%和11.05%。6月龄l/4野血牦牛体高、体斜长、胸围和体重比同龄家牦牛增加4.78cm、5.10cm、6.74cm和7.94kg,分别提高了6.70%、6.90%、7.58%和20.00%(P<0.01)。结果表明,给家牦牛导入野牦牛血可促进牦牛的生长发育。
The indexes of growth and development of the yaks with 1/2 wild blood and the domestic yaks were determined and compared at the birth and the age of six months. The results showed that the withers height, body oblique length, chest girth and body weight of the yaks with 1/4 wild blood at the birth increased 1.80cm, 3.42cm, 2.28cm and 1.27kg, or improved 3.51 %, 7.33 %, 4.12% and 11.05 %, that those of neonatal domestic yaks, respectively; the ones at age of six months increased 4.78cm, 5. 10cm, 6.74cm and 7.94kg, or improved 6.70%, 6.90%, 7.58% and 20.00% than those of contemporary domestic yaks （P 〈 0.01 ）, respectively. These results suggested that the growth and development of the yak were improved by means of intrduction of the blood of wild yaks.
