摘要: 本试验选取了大庆地区某奶牛群11头泌乳奶牛,检测补铜前后奶牛血浆铜含量和铜蓝蛋白(CP)活性的变化,同时分析了两者相关性。结果表明:补铜前血浆铜在10.93 μmol/L以下者占被检牛数的54.55%(6/11),其血浆CP活性降低,两者呈现中度相关性(R2=0.53);补铜后血浆铜含量与CP活性均极显著增高(P<0.01),血浆铜含量达到正常范围,两者呈现低相关性(R2=0.12)。〖JP〗结论:该奶牛场泌乳奶牛群中存在低铜血症病牛,血浆铜蓝蛋白可以作为奶牛低铜血症的一项检测指标。

Abstract: Plasma copper concentration and ceruloplasmin(CP) activity of 11 lactating dairy cows from a farm were detected in Daqing, and a correlation of both parameters was analyzed, before and after addition of copper preparation to diet. Results shown that before addition of copper preparation, ratio of dairy cows with plasma Cu level below 11.1 μmol/L were 54.54%, and activity of plasma CP was lower than normal level, but correlation of both is better positive(R2=0.53). After addition of copper preparation, both were increased(P<0.01), plasma copper concentration were in normal range, but correlation of both is lower positive(R2=0.12). Conclusion obtained that hypocupremia existed in this dairy farm, the activity of plasma CP may be a detecting index of hypocupremia.
