摘要
采用荧光法对西宁地区三个奶牛场的29头(A,B,C 场分别为10,11,8头)奶牛的乳样进行硒含量分析。检查结果表明:A,B,C 三场平均乳硒含量分别为19.93ng/ml,21.01ng/ml,13.40ng/ml,B 场和 C 场间存在着极显著差异(P<0.01);58.62%的被检牛乳硒在20ng/ml 以下,17.24%的被检牛乳硒在10ng/ml 以下。初步证实西宁地区存在着奶牛缺硒的状况。
The milk selenium concentrations were analysed in 29 cows selected from 3farms in Xining area (the numbers of cows in Farm A,B and C were 11,10 and 8,respectively)by fluorimetry.The results showed that the average milk Se concentrations inFarm A,B and C were 19.93,21.01 and 13.40ng/ml,respectively.There was a significantdifference in the average milk Se concentrations between Farm B and Farm C ( P<0.01).58.62% out of examined cows had milk Se concentration less than 20ng/ml.17.24% out ofexamined cows had milk Se concentration less than 10 ng/ml.It has preliminarily been con-firmed that the selenium deficiency in cows exists in Xining area.
