奶牛蹄病与矿物元素相关性研究

目的]探究奶牛体内矿物元素含量与蹄病的关系。方法]从某大型集约化奶牛场随机抽取8头患蹄病的奶牛和8头健康奶牛,采用原子吸收分光光度法检测患蹄病奶牛与健康奶牛血清中一些矿物元素(K、Fe、Cu、Mg、Mn、Na、Zn、Ca)的含量,分析了矿物元素的代谢与奶牛蹄病之间的关系。结果]与对照组相比,试验组奶牛血清中Zn和Mn含量差异极显著(P0.01),试验组Ca和Mg含量差异显著(P0.05),试验组K、Fe、Cu和Na含量差异不显著(P0.05)。结论]患蹄病奶牛内矿物元素代谢异常,特别是与骨骼生长发育有关的元素代谢紊乱,容易导致蹄病的发生。

Study on the Relationship between Mineral Elements and Hoof Disease in Dairy Cows

Objective] To discuss the relationship between the content of mineral elements in dairy cows and hoof disease.Method] Eight dairy cows with hoof disease and eight healthy dairy cows were randomly selected from a large-scale intensive dairy farm to determine the con-tent of several kinds of mineral elements ( K, Fe, Cu, Mg, Mn, Na, Zn, Ca) in the serum of dairy cows with hoof disease and healthy dairy cows by atomic absorption spectrophotometry.And the relationship between the metabolism of mineral elements and the hoof disease of dairy cows was analyzed. Result] The content of Zn and Mn in the serum of dairy cows in experiment group had extremely significant differences with that in control group(P<0.01),and Ca and Mg contents in experiment group had significant differences in experiment group with that in control group(P<0.05),but the contents of K,Fe,Cu and Na in experiment group had no significant difference with that in control group (P >0.05).Conclusion] The metabolism of mineral elements in the dairy cows with hoof disease is unusual, especially the metabolism dis-order of elements related with the bone growth and development.
