The study aimed to verify the synchronization of mares genetic grouping Baixadeiro using PGF2α. Weused 8 mares being established two synchronization protocols - Protocol I: IM PGF2α dose; Protocol II: twodoses (PGF2α, IM) with 10-day interval. After 72 hours were monitored daily by means of ultrasound to monitorfollicle development. The evaluated mares showed interval between treatment and ovulation 11,16 ± 1,46 daysfor T1 and 5,2 ± 0,9 days for T2, with statistically significant difference (P < 0,05). As the diameter of the preovulatoryfollicle was found average of 38,08 ± 0,97 at T1 and 37,31 ± 3,45 in T2, with no significant differencebetween them (P > 0,05). Thus, treatment with two doses of PGF2α promotes return to ciclicity and is effective insynchronizing Baixadeiro mares which had follicular development patterns within the expected range for thespecies.(AU)
