Based on the wide use of estradiol benzoate (EB) in timed-AI (TAI) protocols, with this research we aimed to compare the effect of different doses of EB in synchronization of ovulation and resynchronization at 14 days after TAI in suckled Nelore beef cows. Therefore, this dissertation consists of two studies. In the first study we compared three EB doses (1 mg, n= 20; 1.5 mg, n= 15; and 2 mg, n= 21) associated with a progesterone device (P4) at the beginning of a synchronization protocol for TAI in primiparous (n= 20) and multiparous (n= 36) beef cows. Follicular wave emergence (FWE) did not differ (P > 0.05) among treatment groups, as well as the other features. The FWE occurred later (P < 0.05) in primiparous ...
