In Vitro Maturation of Oocytes from Norwegian Semi-domestic Reindeer (Rangifer tarandus)

Abstract

In vitro maturation of oocytes has been described for several species, but to our knowledge this is the first attempt to mature oocytes from reindeer in vitro. Reindeer are seasonal breeders with their main period of breeding activity starting in the beginning of October. Little knowledge exists about in vivo oocyte maturation, fertilization and development of the early embryonic stages after fertilization. The aim of the present study was to examine whether reindeer oocytes collected out of breeding season could be matured in vitro in conventional medias used for bovine oocytes.
