The present experiments were conducted to optimize in vitro fertilization conditions for zona pellucida-free (ZP-free) oocytes and their subsequent development. The results demonstrated that: (1) maximal fertilization efficiency was achieved at 200 s

At present, it is possible to transfer pig embryos directly into the uterine body of sows by nonsurgical procedures. The aim of this study was to develop a procedure for nonsurgical embryo transfer (ET) into the upper part of one uterine horn in gilt

Oviduct-specific glycoprotein (OGP) displays estrus-associated regional and temporal differences in expression and localizes to the zona pellucida, perivitelline space, and plasma membrane of oviductal oocytes and embryos, suggesting that it may have
