This study was conducted to investigate the effects of maturaton medium and porcine follicular fluid on in vitro maturation of porcine follicular oocytes. The results obtained are as follows; 1. When the oocytes were cultured for 42 hours, the maturation rate was significantly (P<0.05) higher in TCM-HEPES(75.5%) than Ham’s F-10(60.9%) and mKRB(60.7%) medium. The optimal medium for the maturation of porcine oocytes in vitro was the TCM-HEPES medium. 2. When the oocytes were cultured for 42 hours in TCM-HEPES medium with 10, 20 and 30% of porcine follicular fluid(pFF), the maturation rates of porcine oocytes were 69.1, 65.6 and 63.3%, respectively. The maturation rate(51.4%) of oocytes cultured without pFF was significantly(P<0.05) lower than that of oocytes cultured with pFF. 3. The maturation rates of porcine oocytes cultured for 42 hours in TCM-HEPEs medium with 3 different porcine follicular fluid treatments were 68.6%(centrifused), 72.3%(filtered) and 73.1%(heat treated), respectively. The maturation rate(49.4%) of control group without pFF treatment was significantly(P<0.05) lower than that of oocytes cultured with pFF treatment.
