Resumo: The aim of this study was to compare two protocols of estrus synchronization in Santa Inês ewes. Thirty-eight ewes were randomly divided into two groups of estrus synchronization: protocol PGF2? (two doses of 0.530 mg of PGF2?, nine days apart) and protocol MAP+eCG (intravaginal sponge impregnated with medroxyprogesterone acetate, for 12 days, and then an injection of 250 IU of eCG). The experiment was in a cross-over design, two estrous cycles apart. On the final day of protocol, a transrectal ultrasound examination was carried out to measure the size of the largest and second largest ovarian follicles and on day 7 of estrous cycle blood was collected to measure serum P4 concentration. Laparoscopy was carried out on day 11 after the end of protocols to count corpora lutea. Synchronization rate, size of largest and second largest ovarian follicles, interval between the end of the protocol to estrus and ovulation rate did not differ between protocols. Ewes synchronized with MAP+eCG had greater serum P4 concentrations than ewes synchronized with PGF2? (3.9 and 2.8 ng/mL, respectively, P

Foram utilizadas 38 fêmeas ovinas submetidas a dois protocolos de sincronização de estro, com os seguintes protocolos: PGF2? (duas doses de 0,53 mg de D-cloprostenol com nove dias de intervalo) e protocolo MAP+eCG (pessário intravaginal com 50 mg de acetato de medroxiprogesterona por doze dias e no momento da remoção do dispositivo aplicação de 250 UI de eCG, IM). Submeteram-se as ovelhas aos diferentes protocolos, com intervalo de dois ciclos estrais. Procedeu-se a uma ultrassonografia transretal no último dia do protocolo, para avaliação do diâmetro do maior e do segundo maior folículo, e à coleta de sangue no dia sete do ciclo estral, para avaliação da concentração sérica de P4. Exame laparoscópico foi realizado no dia 11, após o fim dos protocolos, para contagem de corpos lúteos. Para os parâmetros taxa de sincronização, diâmetro do maior e do segundo maior folículo, período do final do protocolo ao estro e taxa de ovulação, não se observaram diferenças entre os mesmos. Foi observado que o protocolo MAP+eCG produziu concentrações séricas de P4 maiores do que o protocolo PGF2?
