Biochemical and Developmental Evidence That Ooplasmic Maturation of Prepubertal Bovine Oocytes Is Compromised

Our previous studies have shown that oocytes collected from prepubertal calves lack developmental competence. The overall objective of this study was to assess causes by comparing biochemical and physiologic changes during in vitro maturation of oocytes collected from ovaries of adult cattle at slau...

Zusammenfassung:	Our previous studies have shown that oocytes collected from prepubertal calves lack developmental competence. The overall objective of this study was to assess causes by comparing biochemical and physiologic changes during in vitro maturation of oocytes collected from ovaries of adult cattle at slaughter and from superstimulated calves (
