With the objective of evaluating the Croton nepetaefolius Baill in the transcervical harvest of ovineembryos, we used twelve sheeps and two rams of Rabo Largo breed. After estrus synchronization andsuperovulation, the females were submitted to the embryonic transcervical harvest, being randomly distributedinto three groups (n = 4). The PGF2α group received 75 μg of cloprostenol (IM), twenty four hours beforeharvest; and groups OECn100 and OECn300 received in the background of the vaginal sac, five minutes beforeharvest, 100 μg / mL and 300 μg / mL of the oil, respectively. We used ANOVA and the Tukey test for the resultsanalysis, at a probability of 5%. There was no significant difference for all parameters, between the treatmentgroups (P > 0.05). Croton nepetaefolius Baill essential oil did not facilitate cervical transposition of allharvested animals and did not result in embryo recovery.(AU)
