Age and Hormonal Dependence of Acquisition of Oocyte Competence for Embryogenesis in Prepubertal Calves1

1 Feb 1997

Abstract excerpt

This research was designed to improve our understanding of oocyte maturation and acquisition of developmental competence of oocytes using prepubertal heifers as a model. Oocytes were collected by ultrasound-guided transvaginal oocyte retrieval from 20 age-matched calves at 5, 7, 9, and 11 mo of age that had or had not received gonadotropin stimulation. Numbers of oocytes recovered from unstimulated heifers...
