Abstract: The study was conducted in postpartum cows which were brought for artificial insemination during natural estrum. A total of 40 calved animals were used in this study. One ml of prostaglandin F2α (5 mg) were mixed along with 39 ml of distilled water to make 125 µg of prostaglandin F2α (subluteal dose) per ml and injected through ear vein at the time of artificial insemination (AI). The control cows were inseminated without any treatment. Transrectal ultrasonographic study of the ovary was done to study follicular status before inseminating the cows. Ovulatory response in treatment and control were monitored by ultrasonography on day 10 post AI. The pregnancy was confirmed 60 days after insemination in both the groups. Follicular size at the time of the AI was similar (12.91±0.14 mm and 12.80±0.17 mm) between experimental and control groups and the time of ovulation between experimental and control group was17.93 ±0.63 and 24.25±1.20 hrs, respectively. Conception rate was 70.00% in experimental and 40.00% in control groups.
