摘要
本实验采用荧光分光光度计和原子分光光度计法,对20头正常奶牛和20头有蹄病奶牛蹄角质、血清中的钙、磷、铜、锌、铁、锰离子含量进行测定。结果表明病牛、正常牛血清中钙、磷含量比分别在2.47mg～2.61mg、1.62mg～2.26mg之间,而病牛、正常牛蹄角质中钙、磷含量比分别在2.22mg～2.47mg、1.61mg～1.73mg之间,其中血清和蹄角质中尤以P含量的降低较为明显;正常牛蹄角质和血清中铜含量低于病牛,而正常牛蹄角质和血清中锌含量高于病牛。正常牛、病牛的蹄角质血清中钙、磷、铜、铁、锌离子的含量存在明显的差异(p<0.5)。结果表明,低钙、低磷、低锌、高铜是奶牛蹄病发生的主要因素。
The contents of Calcium (Ca),Phosphorus (P),Copper (Cu), Zinc (Zn), Manganese (Mn) in hoof horniness and serum of 20 normal and 20 hoof disease milk Cows were investigated by fluorescence and divide light photometer. The result showed that the contents of Ca and P in serum of normal and hoof disease milk cows respectively are 2.22mg^2.47 mg and 1.61mg^1.73mg, in which, the content of P in serum and hoof horniness was lower obviously. The content of Cu in serum and hoof horniness of normal milk cows was lower than hoof disease milk Cows, but the content of Zn in serum of normal higher than of hoof disease Cows. The contents of Ca, P, Cu, Fe and Zn in hoof horniness and serum had evident difference between normal milk cows and hoof disease milk cows(p<0.05) The main factors of hoof disease in milk Cows are lower Calcium. Lower phosphorus. Lower Zinc and higher Copper.
