Resumo: Abstract: Goats are seasonal breeders depending on breed and latitude. Among the hormonal methods used in controlled reproduction programs, there are those that mimic the activity of the corpus luteum and those that inhibit it. Prostaglandin (PGF2?) fits the latter, with the advantage of having a better cost-benefit, since it is cheaper and more natural method, as it has fewer side effects than progestin devices. In addition, the literature is incipient regarding follicular and ovulatory data in goats subjected to PGF2? or its analogues. This study aimed to check in dairy goats the efficiency of estrus synchronization treatment using two doses of d-cloprostenol administered in different intervals, during the natural breeding season. The results quoted above suggest that the administration of dcloprostenol in cyclic dairy goats can efficiently synchronize estrus and ovulation and this fact encourages further studies using these protocols in association with Fixed Time Artificial Insemination in goats. [Efeitos de duas administrações de d-cloprostenol feitas em diferentes intervalos no estro e na ovulação em cabras leiteiras cíclicas].
