The main objective of this study was to examine the effects of serum and gonadotropins supplement during in vitro maturation(IVM) of bovine oocytes on nuclear maturation and embryo development, and we also examine the cell number. 1. The first polar body(PB) extrusion rates of Korean native cow(KNC) oocytes matured in medium with FBS or gonadotropins were similar among treatment groups. The development rate to the blastocyst stage was significantly higher in the group of both supplement FBS and gonadotropins(26.0%) than in the group of non-supplement(9.9%) and gonadotropins (12.0%).
