The follicular dynamics and luteal regression were studied in 12 Gir and seven Nelore cows, treated with analog prostaglandin F2a, between day 10 and 12 of the estrous cycle. The synchronization rate was higher than 92% for the two breeds, and the ovulation of second dominant follicle occurred in 72.7% of Gir and all Nelore cows. Ovulatory follicle diameter for Nelore was lower (11.0 ± 0.9 mm) than Gir cows (13.0 ± 1.7 mm). The average intervals from treatment to […]
