The present study was carried out to compare plasma progesterone level of normal cycling and repeat breeding Ongole grade cows. On the beginning of the luteal phase, blood samples were collected from 15 fertile and 15 repeat breeding Ongole grade cows. Progesterone hormone level was measured using progesterone hormone kit (DRG, Germany). The data were analyzed using independent sample t-test to determine the differences of progesterone level in repeated breeding and fertile cows. The finding of the study showed significant different progesterone level of between repeat breeding and fertile cows. Repeat breeding cows were found to have lower levels of progesterone level (1.17 ± 0.39 ng/ml) than that of fertile cows (3.07 ± 0.33 ng/ml). Finally, progesterone level of repeat breeding Ongole grade cows was lower than fertile cows. Low level of progesterone can have some effects on reproductive problems as repeat breeding.
