Resumen:
Were realized a research with the aim of compare the pregnancy rate obtained with two different protocols in buffaloes of Mediterranean breed, in the north of Corrientes, Argentina. The experiment was realized between the monts of May and July of year 2009. In totally, were used 120 pluriparous buffaloes, with calves. The buffaloes were divided in two groups; Group 1(G1) n = 59, Ovsynch protocol, with GnRH, PGF2á and GnRH. The resynchronization: day 28, 8 ìg GnRH; day 35 pregnancy diagnoses through ultrasonography and PGF2á to the animals diagnosed empty; day 37, GnRH and day 38 FTAI. While Group 2 (G2) n = 61 was used intravaginal dispositives with progestagens. Synchronization: day 1 Estradiol Benzoate and putting in the dispositives; day 7, PGF2á and put out the dispositives; day 8, EB and day 9 FTAI. Resynchronization: day 28, EB and second use dispositives, during 7 days; day 35, pregnancy diagnoses through ultrasonography and PGF2á to the animals diagnosed empty; day 36, EB and day 37 FTAI. Starting from the day 55 were 75 and 80% and 83 and 87% for the first insemination, resynchronization and final pregnancy for G1 and G2 respectively. Concluding, that were differences in the pregnancy rate at first FTAI for G2. In the other dates were no significant differences.
