Abstract: This study aimed to determine the effect of giving the PGF2α hormone to Bali cows on the success rate of artificial insemination. The sample used was 120 non pregnant Bali cows. This study consisted of 2 treatment groups, those with and without PGF2α hormone injection 60 samples respectively and then artificially inseminated. The parameters observed were onset of estrus, quality of estrus, and pregnancy rate. The data obtained were analyzed by T-test. The results of the study showed that the onset of estrus appeared the earliest at the 24-30 hours (63.33%) and the slowest at the 96 hours (3.33%) after injection. Estrus quality at score 3 and pregnancy rate did not differ between with and without PGF2α injection (73.33% vs 68.33% and 81.67% vs 78.33%). In conclusion, the onset of estrus 63.33% occurred at the 24-30 hours and only 3.33% appeared at the 96 hours after injection, while the quality of estrus and pregnancy rates did not differ between with and without PGF2α injection.
