摘要: 为探讨促孕散治疗持久黄体的作用机理,本研究通过直肠检查结合B超直肠检查对持久黄体奶牛做出诊断后口服促孕散,应用B超每3 d对黄体直径、卵泡数量、卵巢长度、卵巢宽度、子宫角纵径和子宫颈纵径进行测量,并统计1次,与用药前进行对比。30头持久黄体奶牛口服促孕散后,治疗有效头数25头,有效率为83.3%。停药后第1天卵巢出现小卵泡和中等卵泡,停药后分别在第10和19天大卵泡数量最多,部分奶牛出现发情并排卵,与用药前卵巢相比,结果发现左、右侧卵巢长在停药后均降低,但差异不显著(P>0.05);左、右卵巢宽在停药后均降低,但差异不显著(P>0.05);子宫颈纵径和子宫角纵径均在停药后升高,但差异不显著(P>0.05)。结果表明,B超是诊断奶牛持久黄体的有效手段,中药促孕散对持久黄体奶牛卵巢和子宫形态等指标具有一定的影响,可以促进黄体的溶解。

Abstract: The objective of this study was to investigate the mechanism of taking fertility-promoting power to treat persistent curpus luteum in dairy cows. Dairy cows of persistent corpus luteum were diagnosed by rectal palpation and B-mode ultrasound scanning. These cows were determined 24 h after taking medicine and some morphological indexs included diameter of corpus luteum, follicular number, length of ovary, width of ovary, longitudinal diameter of cervix uterus and longitudinal diameter of horn uterus were counted every three days by ultrasound scanning. The effective number was 25 and effective ratio was 83.3% among 30 dairy cows of persistent corpus luteum. The change of morphological indexs of ovarian and uterine before and after taking medicine were as follow. Medium and small follicules were appeared on ovary after finishing treatment for 1 day and most of large follicule were appeared after finishing treatment for 10, 19 days respectively and part of them appeared estrus and ovulation. The length of ovary on right and left side decreased not significantly (P>0.05) after finishing treatment compared with that of dairy cows before taking medicine, respectively.The width of ovary on left and right side decreased not significantly (P>0.05) after finishing treatment compared to that of dairy cows before taking medicine, respectively. The longitudinal diameter of cervix uterus and horn uterus increased not significant difference after finishing treatment (P>0.05). The results showed that B-mode ultrasound scanning was a effective method to diagnose persistent corpus luteum and taking orally fertility-promoting power had obvious effect on morphological indexs of ovaries and uterine of in dairy cows.
