摘　　要：[目的]通过对牦牛毛绒品质和毛微量元素的测定,得出其是否与牦牛抗寒性能有关。[方法]选择西藏阿里地区的不同年龄阶段牦牛对毛绒品质和毛中钙Ca、铜Cu、铁Fe、镁Mg、锌Zn等指标变化进行分析。[结果]不同年龄半野血牦牛的被毛分析得出,随着年龄的增长毛绒细度逐渐增加且差异显著(P<0.05);6~8岁半野血牦牛被毛和血液中的铁、钙含量较高,可能与牦牛为了适应缺氧气候条件有关。[结论]牦牛毛绒品质和微量元素随着年龄的增长有增长趋势,以6~8年龄阶段较好,这将对牦牛抗寒能力的改善及其他高原品种营养代谢调控,疾病预防等方面提供数据支撑。[Objective]This study can analyze the cold-resistant correlation between the quality hair and trace elements in yak hair.[Methods]The yaks different ages of quality wool and the changes of Ca,Cu,Fe,Mg,Zn in hair were recorded and analyzed by in Tibet Ali area.[Results]The results showed that the wool fineness of semi-wild blood yak increased with the increase of age(P<0.05),In aged 6-8 years old,semi-wild blood yaks have the correlation with the content of iron and calcium in their blood and trace elements,which may be related to the adaption to lack of oxygen conditions of the yak.[Conclusion]The wool quality and trace elements of yak have an increasing tendency with the increase of age,especially in the 6-8 age stage,which will provide scientific basis in the cold resistance improvement of yak and the nutrition and metabolism regulation of other plateau breeds,disease prevention and other aspects.
