Abstract: The aim of this work was to evaluate the efficiency of two hormonal treatments in the synchronization of estrus in Criollas Serranas goats during the summer season. It was carried out using 79 female goats, with a completely randomized design, comparing the following treatments: T1, Prostaglandin F2a (n=27): two doses of 325 mg/goat (sc) of cloprostenol, separated 12 days one from the other; T2, Progestagen (n=26): intra vaginal sponge with 60 mg of acetate medroxiprogesterone, during 12 days, with out any associated luteolytical agent and T3, Control group (n=26): received no hormonal treatment. The percentage of synchronized estrus, average time until the manifestation of the estrus, and the fertility of these goats, measured through the percentage of kidding, were evaluated. The estrus were detected during 10 days post treatment. Data were analyzed by χ2 test and ANOVA. There were found highly significant differences between the percentage of the detected estrus in the hormonal treatments and the control group ( T1, 66.7%; T2, 65.4% y T3, 26.9%). No significant differences were found for the average time in the manifestation estrus in the hormonal treatments (T1, 90.7 ± 11.6 h.; T2, 77.6 ± 7.8 h.) and fertility was not altered by the hormonal action (T1, 50%, T2, 70.6% y T3, 71.4%). It was concluded that the hormonal treatments used were efficient to synchronize the estrus without altering the fertility of the goats.
