Abstract: The effects of collection method，estrous cycle were discussed in this paper.The results were as follows: there was significantly difference among isolating methods in cleavage rate of ovine oocytes (27.9%,49.5%；P<0.05); the maturation rate of A and B grade was significantly higher than C grade(75.3%、64.4%,29.1%，P<0.01) and the same to cleavage rate(42.5%,35.8%,16.0%，P<0.05); the oocytes from different estrous cycle had the same developmental capability.
