dc.description.abstractThe objective of this trial was to compare the efficacy of short-term and long-term progesterone treatments to induce ovarian activity of sheep both during breeding and anestrus seasons. The experiment was performed at two periods, during the breeding and the anestrus seasons on 2 different groups of 30 ewes. During each period, the ewes were randomly allocated to 2 groups of 15 ewes which received a short term (7 days) or a long term (12 days) progesterone treatment, respectively. The progesterone treatment consisted on a vaginal sponge containing 30 mg fluorogestone acetate (FGA) inserted into the vagina of the ewes for 7 or 12 days. Triaprost tromethamine, an analogue of PGF(2 alpha), was intramuscularly administered to all ewes at the moment of the sponges withdrawal. Afterwards, 400 IU of PMSG were intramuscularly administered to all the ewes. Mean percentage of estrous, pregnant and lambing sheep were 100%, 86.7 % and 80% in both the short term and the long term treated groups during the breeding season. The mean litter did not differ between the short term and the long term treated groups (1.8 vs 1.7). During the anestrus season, the mean percentage of estrous, pregnant, lambing sheep and mean litter size were 86.6%. 76.9%. 61.5% and 1.5 in the long term treated group and 93.3%. 85.7%. 71.4% and 1.5 in the short term treated group, respectively. The short-term progesterone treatment was effective to synchronize oestrus in sheep during both breeding and anestrus seasons.en_US
