摘要
[目的]探讨奶牛和绵羊血清骨型碱性磷酸酶活性在不同怀孕期的变化。[方法]采用磷酸苯二钠法,对33头荷斯坦奶牛和29只藏系绵羊不同怀孕期血清碱性磷酸酶活性及其酶保存率进行了测定。[结果]所有奶牛和绵羊血清碱性磷酸酶活性均在正常范围内,但奶牛怀孕中期的碱性磷酸酶活性比未怀孕、怀孕前期、怀孕后期明显降低(P<0.05);碱性磷酸酶保存率均低于26%,表明奶牛和绵羊血清碱性磷酸酶均来自骨骼。[结论]奶牛和绵羊血清骨型碱性磷酸酶活性在怀孕中期呈下降趋势。
[Objective] The research aimed to study the change regular of serum bone alkaline phosphatase activity of cow and sheep in different period of pregnancy.[Method] 33 Holstein cows and 29 Tibet-sheep were chosen to study the alkaline phosphatase activity and its enzyme retention in different period of pregnancy with disodium phenyl phosphate method.[Result] Activity of serum alkalinity phosphatase of cows and sheep was in a normal range.But activity of alkalinity phosphatase of mid pregnancy cows was obviously lower than before pregnancy and not pregnant and later pregnancy （P〈0.05）. Alkaline phosphatase retention was lower than 26%. It showed that serum alkalinity phosphatase of cows and sheep came from the skeleton. [Conclusion] Activity of serum bone alkalinity phosphatase of cows and sheep showed a declining trend in mid pregnancy.
