摘要

The aim of the study was to determine the reproductive characteristics of Pelibuey ewes synchronized (T1: n=7), and puberty induced (T2: n=7). Ewes in T1 were pre-synchronized; and seven days after FGA intraviginal sponge were inserted to all ewes during 12 day. Two days prior to sponge removal ewes were injected with eCG. Estrous were observed in 100% of ewes in T1 and T2. Time of estrous was not significant (P>0.05) with values of 21.4 ± 2.2 h and 24.2 ± 3.2 h for T1 and T2. Estrous duration was 60.5 ± 6.6 y 41.3 ± 3.6 for T1 and T2 (P 0.05) with values of 24.5 ± 1.7 and 24.2 ± 4.7 h, 13.4 ± 1.2 and 14.0 ± 0.6 h, 18.1 ± 2.7 and 21.3 ± 3.1 ng mL-1 for T1 y T2 respectively. Pregnancy rate was not significant among treatments with 100% and 85.71% for T1 and T2, respectively. The experiment conclusion was that the used of FGA and eCG in Pelibuey ewes are good alternatives to induce puberty, with acceptable reproductive response. The implementation of these protocols is feasible in AI at fix time programs.
