Different strains have different reaction to the delay of oviducts in body after animal death. After 10min delay C57BL/6 mouse oocytes have death rate of 56.5%,significantely higher than Kunming mouse (47.6%);Spontaneous activation rates were respectively 13.3% and 46.0%, C57BL/6 were obviously lower than Kunming mouse.4. The oviducts were obtained after being delayed 5min 24h after the mice were injected with hCG. The oocytes were cultured in CZB. About 81.1% occurred spontaneous activation, evidently lower than parthenogenetic rate (96.4%) with SrCl_2. Spontaneous activable oocytes had high cleavage rate(93.2%) and 4-cell rate(87.3%). However, spontaneous activable oocytes had blastula development rate(18.7%) as low as parthenogenetic oocytes by SrCl_2(22.9%).

4H was the best time of bovine oocyte activationin the 6-DAMP, and the cleavage rates and blastula rates could reach 85.1% and 26.8%. 4. IVF-100 was used in vitro fertilization, because IVF-100 was not needed to prepare usually,store conveniently, and gain a higher cleavage rates. After the oocytes have matured for 20h, theywere digested by permease and treated with suctionpipe.
