| 摘 要： | 测定了天祝白牦牛母牛、兰州荷斯坦母牛胎儿胎盘和被毛巾的１１种微量元素含量。结果证明，天祝白牦牛胎儿胎盘和被毛中的微量元素铜、铁、镁、砷、钼的含量极显著地高于兰州荷斯坦牛。是天祝白牦牛适应高山少氧生态环境的繁殖特性，也是适应高山少氧环境的特性之一。

| Abstract: | Eleven trace elements in fetal cotyledon and dam hair of female Tianzhu whiteyaks and Lanzhou Holstein cows were measured.The results showed that the contents of Cu,Fe,Mn,Mg,As and Mo were significantly higher in the yak than in the cow. This mightrepresent the reproductive characteristics that the Tianzhu white yaks adapt to ecological en-vironment of high motintain and low oxygen content in air,and is one of the characteristics ofthe animal to adapt to the environment. |
