Effect of Different Changing Media Volume and FBS on The Development of Bovine Parthenogenetic Embryos in Vitro

This study aimed to investigate the effect of changing media volume and un-inactivated serum on the developmental potentiality of bovine parthenogenetic embryos.The results indicated that the blastocyst developmental rates of 1/2 groups were significantly higher than of 1/4 and 3/4 groups(P0.05) when SOFaa was used as the basic medium,they were 38.84%,23.39%,21.71% respectivily.The cleavage rates and blastocyst rates of embryos had no significantly difference between inactivated and un-inactivated serum groups(P﹥0.05).
