Efecto de la gonadotropina coriónica equina (eCG) en la tasa de preñez en vacas Brahman con protocolos de inseminación artificial a tiempo fijo (IATF) en condiciones de altitud

Abstract

This research aimed to evaluate the pregnancy rate in Brahman cows with the inclusion of the Equine Chorionic Gonadotropin (eCG) hormone in an IATF protocol under altitude conditions at 300 meters above sea level. We worked with 60 experimental units, distributed in two groups of 30 animals, applying the hormone to a single group. Subsequently, a gynecological check-up was performed by ultrasonography 60 days after artificial insemination. The result was not significant.
