The results showed that the rates of mature oocyte were 75.2%, 73.1%, 69.8%, 63.5%and oocyte at telophase of MI were 16.3%, 15.9%, 16.9%, 27.0%, respectively. The rates of maturation of oocytes cultured in TCM199 with serum, EGF and TGFαwere significantly higher than that of with BSA team (P<0.05) and the number of oocyte stayed at telophase of MI in TCM199 with serum, EGF and TGFαteam were significantly less than that with BSA team(P<0.05); Significant higher rates (66.6%, 66.6%, 73.6%) of normalα-tubulin distribution in oocytes cultured in TCM199+ serum, EGF and TGFαwere compared to that of TCM199+BSA(43.3%)(P<0.05). The rates of oocyte with cortical granules in cortex were 58.8%, 33.9%, 54.7%and 47.9%respectively, there was significant difference between oocytes cultured with serum, EGF and BSA(P<0.05). In conclusion, TGFαand EGF can promote the oocyte nuclear transition from telophaseⅠto metaphase of meiosisⅡ, and improved the expression and distribution ofα-tubulin during the ovine oocytes maturation; EGF and serum could promote oocyte cytoplasm maturation. The results suggested that EGF and TGFαmight substitute some substance in serum to improve the quality of oocyte nucleus maturation in vitro, but EGF might be more functional than TGFαto promote the maturation of ovine oocyte ooplasm.
