The determination of progesterone in milk sampled on the day of insemination is used for fertilization check in dairy cattle. Thus, the corpus luteum function confirms insemination failures due to the false estrus. By this way it is possible to detect 10 to 20 per cent of cows which cannot be successfully inseminated. Further estimation is performed 3 weeks after the insemination when low concentration of progesterone reflects an insemination failure. By this way it is possible to follow up cows inseminated without success and without any clinical symptoms of the next estrus. The repeated estimation of progesterone can objectively monitor the corpus luteum function. This is of great importance for the confirmation of puerperal anestrus, diagnosis of fertility disorders and/or assessment of therapy of sexual cycle disorders.
在授精当天采集的牛奶中测定孕酮用于奶牛的受精检查。因此,黄体功能可确认因假发情导致的授精失败。通过这种方式,可以检测出10%至20%无法成功授精的奶牛。在授精3周后进行进一步评估,此时孕酮浓度低反映授精失败。通过这种方式,可以跟踪授精未成功且没有下一发情周期任何临床症状的奶牛。重复测定孕酮可以客观地监测黄体功能。这对于确认产后发情停止、诊断生育障碍和/或评估性周期紊乱的治疗非常重要。
