This study was carried out to investigate whether the GV oocytes from carcasses could be utilized. Carcasses were preserved at 10℃, 15℃, 20℃ and 25℃ for 8 hours, 14 hours, 24 hours, or 48 hours after mice were killed and GV occytes were collected. After maturating in vitro, these oocytes were fertilized in vitro with the general procedure in advance.
