Background: evaluation of reproductive behavior in Creole cows is important to determine several parameters, such as fertility, that show the physiologic reproductive mechanisms under different conditions. Therefore, the sequence of events such as ovulation and the subsequent formation of a corpus luteum need tobe considered to establish genetic improvement programs under synchronized or naturally-occurring estrous conditions.

Seventeen days after synchronized estrous detection, cows were observed during seven d to detect the naturally-occurring estrous and its duration. After the onset of both types of estrous the ovaries of each cow were ultrasounded every 8 h to determine diameter of the preovulatory follicle at deviation and its maximum diameter prior to ovulation, as well as its growth rate, time to ovulation and maximum diameter of the later corpus luteum.

Diameters of the dominant follicle what is dominant follicle size deviation and prior to ovulation were similar in both types of estrous. Diameter of corpus luteum 10 d after ovulation was similar in both types of estrous. Results indicate that growth rate of follicle and time from synchronized or spontaneous estrous to ovulation must be considered for estrous cycle manipulation and artificial insemination of Creole cows.

Conclusion: a higher proportion of Creole cows show heat during nighttime, growth rate of ovulatory follicle is higher during synchronized estrous, and time from onset of love hope faith trust quotes estrous to ovulation is longer, when compared with spontaneous estrous.
