The present study was conducted with the objectives to assess the circulating plasma progesterone concentrations in early pregnant cows and in those who suffered embryonic mortality. From the entire herd, a total of 142 (Sahiwal 29 and Hardhenu 113) cows were selected for the study. Out of 142 animals, only 53 animals exhibited non-return to estrus and rest showed estrus signs and behaviour before day 28 post-insemination. Blood sampling from all the 142 animals was carried out on day 15 post-insemination and later from the animals which were confirmed pregnant on day 28 (53 animals) and 45 (51 animals). Animals which were diagnosed with embryonic mortality on day 45 were also subjected to blood sampling. The plasma progesterone concentrations were significantly higher in pregnant cows on all days (Day 15, 28 and 45) as compared to cows with embryonic mortality. The plasma progesterone concentrations in pregnant cows increased significantly (p<0.05) from 1.78±0.05 (Day 15) to 3.23±0.04 (Day 45). The plasma progesterone concentrations in cows with embryonic mortality increased remarkably from 0.75±0.05 (Day 15) to 1.35±0.15 (Day 28). Therefore, the animals suffered with embryonic mortality had lower progesterone concentrations on day 15, 28 and 45 post-insemination than the animals with normal pregnancy. Therefore, luteal insufficiency or other external factors could have been the cause of embryonic mortality.
