Using rectal palpation and laparoscopy, the relationship of ovarian contents to plasma progesterone concentration during the oestrous cycle, early pregnancy and post partum periods in the swamp buffalo (Bubalus bubalis) was studied. During the oestrous cycle, four stages in the lifespan of the corpus luteum were seen laparoscopically. The mean (+/- sd) concentrations of progesterone in plasma in cows with and without a corpus luteum on their ovaries were 1.49 +/- 0.78 ng/ml (n = 31) and 0.14 +/- 0.09 ng/ml (n = 14), respectively. Plasma progesterone levels reflected age-dependent changes occurring in the cyclic corpus luteum. The accuracy of diagnosing ovarian contents was 82 and 91 per cent for rectal palpation and plasma progesterone levels respectively. Approximately 29 per cent follicles (larger than 10 mm) were incorrectly diagnosed as corpora lutea by rectal palpation.
采用直肠触诊和腹腔镜检查，研究了沼泽水牛（Bubalus bubalis）发情周期、妊娠早期和产后卵巢内容物与血浆孕酮浓度之间的关系。在发情周期中，通过腹腔镜观察到黄体寿命的四个阶段。卵巢上有黄体和无黄体的母牛血浆中孕酮的平均（±标准差）浓度分别为1.49±0.78 ng/ml（n = 31）和0.14±0.09 ng/ml（n = 14）。血浆孕酮水平反映了周期性黄体中发生的年龄依赖性变化。直肠触诊和血浆孕酮水平诊断卵巢内容物的准确率分别为82%和91%。直肠触诊将约29%的卵泡（大于10 mm）错误诊断为黄体。
