Growth and regression of ovarian follicles were studied in crossbred cows (n=6), induced with prostaglandin (PGF2 alpha) analogue for luteolysis. After PGF2 alpha treatment, four cows (Group A) ovulated from dominant follicle of first follicular wave and remaining 2 animals ovulated from second dominant follicle (Group B). The intervals from treatment to estrus (P<0.01) and treatment to ovulation (P<0.01) were significantly longer in animals of group B compared to the animals of group A. Significant differences were observed in growth profile of ovulatory follicle between animals of group A and group B with respect to daily growth rate (P<0.01), increase in diameter (P<0.01) and size of the follicle on day 0 (P<0.01).
