Abstract

Milk samples were collected on Days 20, 24, 28 and 40 after insemination. The percentage of fat and thr progesterone concentration in the milk were correlated (P < 0.01). Progesterone concentration in the milk of pregnant buffaloes (24.83 +/- 3.85 ng/ml) was significantly higher than that in non-pregnant animals (2.89 +/- ng/ml) on Day 20 and the difference between the two increased with time after insemination. The detection of non-pregnant animals was 100% successful at all times but the diagnosis was correct for 66, 68, 81 and 83% of animals tested on Days 20, 24, 28 and 40 respectively and predicted as pregnant.

摘要

在授精后第20天、24天、28天和40天采集牛奶样本。牛奶中的脂肪百分比与孕酮浓度相关（P < 0.01）。在第20天，怀孕水牛牛奶中的孕酮浓度（24.83±3.85纳克/毫升）显著高于未怀孕动物（2.89±纳克/毫升），且两者之间的差异随着授精后时间的推移而增加。对未怀孕动物的检测在所有时间均100%成功，但分别在第20天、24天、28天和40天测试并预测为怀孕的动物中，诊断正确的比例分别为66%、68%、81%和83%。
