本研究通过对饲料地土壤、饲草(料)和饮水中微量元素的分析,估测了武威冷冻精液站牛群的微量元素营养状况。结果表明,土壤全Cu 与全Zn 低于甘肃省和全国的平均值,全Fe 明显低于甘肃和世界平均值;所测饲草(料)的含Mn 量显著低于国内、美加、日本和苏联值,Fe、Cu 和Zn 含量有偏低的趋势。但Se 与Co 的含量较高;饮水中Cu、Fe 含量明显高于某些国内外报道值,Mn 含量较低。根据饲草(料)分析结果对公、母牛日粮配方估算表明,Mn严重低于需要,Cu、Zn 略缺,Se 勉强够,Fe 则足够。这与作者对该牛群被毛、血液和乳的抽样分析结论一致。 In this study, we analyzed the trace element nutrition status of the herd in Wuwei frozen semen station through the analysis of the soil, forage (material) and trace elements in drinking water. The results showed that the contents of total Cu and total Zn in soil were lower than those in Gansu Province and the whole country. The content of total Fe was significantly lower than that of Gansu and the world average. The content of Mn in forage was significantly lower than that in China, America, Canada, Japan and The values ​​of the Soviet Union, Fe, Cu and Zn tended to be low. However, the content of Se and Co is higher. The content of Cu and Fe in drinking water is obviously higher than some reports at home and abroad, and the content of Mn is lower. According to the results of forage (material) analysis, the formula of male and female diets showed that Mn was seriously less than needed, that Cu and Zn were slightly deficient, Se was barely enough and Fe was enough. This is consistent with the author’s sample analysis of the herd’s coat, blood and milk.
