Summary: Abstract: The use of B-mode and color Doppler ultrasonography may replace the use of surgical methods (laparoscopy or laparotomy) in the evaluation of the superovulatory response in sheep, with an accuracy around 74% and 82%, respectively (Oliveira et al. 2018. Reprod Dom Anim, 53:742-750). The ultrasound determination of ovarian response in embryo donor goats still needs to be proven, especially because the non-invasive technique is mandatory when the embryo collection is done by transcervical route. The aim of this study was to correlate the quantification of corpora luteal (CLs) determined by Bmode ultrasound evaluation with the number of recovered structures obtained by transcervical embryo collection of superovulated goats. In view of the above, it is possible to indicate that the B-mode ultrasound evaluation of superovulatory response of goats is feasible and indispensable when the embryos collection is made by non-surgical technique.
