Abstract

The main objective of this study was to evaluate a recumbent left flank approach to bilateral ovariectomy in prepubertal heifersand to develop an optimal surgical technique for this procedure. Both ovaries were removed from 6 Nelore heifers by left flankapproach without any complications, except in 1 heifer, which was believed to have had only 1 ovary based on ultrasound andexploration during surgery, but was later found to have a remaining functional ovary. Ovariectomy via left flank approach inrecumbent prepubertal heifers is feasible and technically easy. This procedure does not involve special instrumentation and,despite the invasive approach, it allows optimal visualization of the ovaries and uterus. (AU)
