【摘要】 选择患持久黄体的不孕奶牛14头进行复方缩宫素乳剂的临床治疗试验．并利用放射免疫方法对部分患牛治疗前后血清孕酮（P4）和雌二醇（E2）水平进行检测。结果发现：复方缩宫素对持久黄体性不孕奶牛的有效率和治愈率均为77．78％、显著高于对照组；患牛在处理后血中E2水平不断升高．P4水平逐渐降低。这些结果表明．复方缩宫素具有溶解黄体和诱导发情的作用。更多还原

【Abstract】 Oxytocin Compound Emulsion(OCE) was used to treat l4 infertile dairy cows with Persistent corpus luteum(PCL). The levels of serum estradiol(E2) and progesterone (P4) were detected by Radio-immunoassay(RIA). The results indicated that the total clinical efficacy rate and the conception rate all were 77. 8%. The concentration of estradiol increased but progesterone decreased after the treatment. The result suggested that OCE was able to indue luteolysis and estrus in inlbrtile cows with PCL.更多还原
