| Abstract: | In vivo developmental potentials of in vivo and in vitro matured oocytes fertilized in vitro were assessed in cattle. One-cell stages produced from in vivo matured oocytes developed into a pregnancy when transferred to the ampulla part of oviducts of synchronized heifers. In vitro matured oocytes achieved high penetration and cleavage rates but did not develop into pregnancies when transferred to synchronized heifers. |
