摘　　要：本试验采用原子吸收光谱法和荧光吸收光谱法对14头屡配不孕奶牛和10头正常奶牛血清铜、锰、锌及维生素A、维生素E水平进行检测分析,旨在了解重庆市某奶牛场奶牛屡配不孕与血清中部分微量元素及维生素水平的关系。结果显示,屡配不孕奶牛血清锌、维生素A和维生素E含量与正常奶牛相比差异显著(P<0.05),血清铜、锰含量与正常奶牛无明显差异(P>0.05)。从检测结果分析推测,血清锌、维生素A和维生素E水平过低可能是造成奶牛屡配不孕的原因之一。In order to probe the relationship between infertility and the levels of some microelement and vitamin,the levels of normal serum copper,manganese,zinc and vitamin A,vitamin E of 14 infertile cows and 10 cows were tested and analyzed by the atomic absorption spectrometry and fluorescence absorption spectrometry.As the results showed,the contents of serum zinc,vitamin A,vitamin E in infertility cows were more significant than that of normal cows（P〈0.05）.Serum copper,manganese content in infertility cows and normal cows were with no significant differences（P〉0.05）.According to the results,our conclusion was as follows.The low levels of the serum zinc,vitamin A,vitamin E might be one of the causes of infertility.
