The researches were made with the goal to induce estrus to the wean sows, during the summer season. To the pluriparous sows we administrate 2 ml Maprelin XP 10 at 24 hours after weaning to the experimental group. Control group didn’t receive any hormonal product. Primiparous sows were split in two groups: to one group we administrate 0.5 ml Maprelin XP 10 at 24 hours after weaning; to the other group we administrate 5 ml P.G. 600 in the weaning day. Weaning to estrus interval was 5.33±0.21 days for 2 ml Maprelin XP group, 5.16±0.24 days for control group, 6.32±0.39 days for 0.5 ml Maprelin XP and 5.18±0.35 days for P.G. 600 group. Proportion in estrus after weaning was 98.01% for 2 ml Maprelin XP group, 96.28% for control group, 89.56% for 0.5 ml Maprelin XP and 91.22% for P.G. 600 group. Fecundity at 28 days after the A.I. was 91.71% for 2 ml Maprelin XP group, 92.26% for control group, 83.41% for 0.5 ml Maprelin XP and 86.61% for P.G. 600 group. Farrowing rate was 86.00% for 2 ml Maprelin XP group, 85.11% for control group, 76.68% for 0.5 ml Maprelin XP and 78.66% for P.G. 600 group.
