ABSTRACT
The objective of this study was to evaluate the efficacy of ovulation synchronization protocols forartificial insemination at fixed time (IATF) during a favorable reproductive season in buffalo females in Baixadamaranhense. The experiment was carried out in July with 100 buffaloes of the Murrah breed. Two protocols forovulation synchronization were applied "GnRH / hCG" and "GnRH / BE". Ultrasonographic evaluations wereperformed to monitor follicular dynamics and ovulation rate and the IATF to evaluate the conception rate. Allthe females responded to the treatments and there was similar follicular growth from the emergency to thefollicular deviation. There was an effect of the ovulation inducer on the diameter of the dominant and ovulatoryfollicle (P <0.05). The ovulation rate was higher in animals subjected to ovulation induction with hCG. Theaverage design rate was 29%. It was concluded that hCG was more efficient in the induction of synchronizedovulation than BE.(AU)
