Abstract

Introduction. Ultrasound-guided follicular aspiration (UGFA) coupled with the in-vitro production of embryos is an important alternative for the use of genetic resources of bovine females of high productive potential. However, the reduced quality of oocytes recovered with this technique is one of the aspects with the highest impact on the efficiency to obtain embryos. Materials and methods. This research compared follicular development with the quality of oocytes recovered by UGFA, in bovine females conventionally over-stimulated with FSH or FSH and hCG. Results. A higher quality of oocytes recovered from animals stimulated with FSH and hCG was seen compared to the ones stimulated with FSH only. Conclusions. Inclusion of Hcg in a scheme for the ovarian over-stimulation with FSH of bovine females subject to follicular aspiration becomes a favorable effect on the quality of recovered oocytes.
