| 摘 要： | 对河曲马主要牧草和全血１０种矿物质营养状况进行了研究，结果表明，当地牧草中Ｓｅ、Ｚｎ含量极显著低于ＮＲＣ（１９８９）规定的马营养需要量（Ｐ〈０．０１），而Ｃａ含量较高，Ｐ含量较低，造成牧草中Ｃａ、Ｐ比较严重失谳（Ｃａ：ｐ达７．６～８．３：１），同时发现牧草中Ｃｕ含量在马营养需要量的临界水平，全血矿物元素含量的分析表明，所测元素性别间均无显著差异（Ｐ〉０．０５）。

| Abstract: | The contents of mineral elements in forage and blood samples of Hequ horses were analyzed. The results indicated that the contents of selenium and zinc in forages were significantly lower than the nutrient standards set for horses by the National Research Council. The content of calcium in forage was undue high and the Ca p nutrition was unbalanced, with a Ca P ratio varying from 7.6 to 8.3. Meanwhile, the concentration of Cu was at the critical level of nutrition required by horses. All mineral elements in blood did not show any significant difference between sexes. |
