This study aimed to investigate the relationship between increases in the luteinizing hormone (LH) profiles in the serum and vaginal mucus of cows induced by gonadotropin-releasing hormone (GnRH). Samples for LH determination were collected from Japanese Black beef cows during estrus, which was induced with a controlled internal progesterone-releasing device and the administration of cloprostenol immediately before GnRH administration and every 30 min from the start of GnRH administration until 6.5 h. The peak serum LH concentration was clearly identified at 2.5 h post-GnRH administration, with serum concentrations returning to near-pre-GnRH-administration values after 6.5 h, whereas the peak vaginal mucus LH concentration was identified 4.5 h after GnRH administration. These results indicate that the LH secretion peak in vaginal mucus appeared about 2 h after peak LH secretion in the serum.
