The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

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 estrus, treatment to ovulation time and from the beginning of the estrus to ovulation were 88.7 and 91.6h, 119 and 113h, 26.5 and 24.3h for Nelore and Gir cows, respectively.
