Efeito do óleo essencial de Croton nepetifolius sobre a penetração cervical em ovelhas mestiças de Dorper e Santa Inês / Effect of the essential oil of Croton nepetifolius Baill on cervical penetration in crossbred Dorper and Santa Inês ewes

ABSTRACT

To evaluate the use of the Croton nepetifolius Baill (OECn) essential oil in cervical penetrability inewe, forty Forty crossbred females of Dorper and Santa Inês were submitted to estrous synchronization anddistributed into four groups (n = 10). A control group and another three groups treated with 200 μg /misoprostol sheep (Misoprostol), 50 μg / mL (OECn50) and 100 μg / mL (OECn100) of OECn oil respectively,before the introduction of an artificial insemination applicator (AI). The depth of cervical penetration and thepassage time of the mandrel of AI were recorded and analyzed using ANOVA and the Tukey and Chi-squaretests. There was no significant difference in cervical penetrability, but the Misoprostol and OECn100 groupspresented a lower penetrability time when compared to the Control group. Therefore, the use of Crotonnepetifolius Baill essential oil facilitates cervical sheep penetration.(AU)
