The present study examined the effects of epidermal growth factor(EGF) and transforming growth factor-$\alpha$(TGF-$\alpha$) on in vitro maturation of porcine follicular oocytes. Basic medium used TCM-HEPES, and oocytes cultured for 42 hours in vitro. The results obtained are as follows; 1. The nuclear maturation rates of EGF-treated groups(10ng/ml, 75.9% ; 30ng/ml, 69.2% ; 50ng/ml, 67.2% ; 100ng/ml, 71.0%) on the porcine oocytes cultured in medium without pFF in vitro were significantly(P<0.01) higher than those of non-treated group(57.1%). When the oocytes were cultured in media with 10%(v/v) pFF, the nuclear maturation rates of 30ng EGF/ml(77.1%) treated group were significantly(P<0.01) higher than those of non-(59.2%) and EGF-treated groups(10ng/ml, 65.4% ; 50ng/ml, 65.5% ; 100ng/ml, 70.4%). 2. The nuclear maturation rates of 30ng TGF-$\alpha$/ml treated group(71.9%) in media without pFF in vitro were significatnly(P<0.01) higher than those of non-(57.1%) and TGF-$\alpha$ treated groups(10ng/ml, 60.4% ; 50ng/ml, 65.4% ; 100ng/ml, 60.0%). When the oocytes were cultured in media with 10%(v/v) pFF, the nuclear maturation rates of 30 and 50ng TGF-$\alpha$/ml(77.4% and 79.6%) treated groups(10ng/ml, 64.2% ; 100ng/ml, 61.6%). 3. On the effect of EGF(30ng/ml) and/or TGF-$\alpha$(30ng/ml) treated groups in medium without pFF in vitro, the nuclear maturation rates indicated 57.3, 60.4, 75.9 and 79.7% in media with no EGF & TFG-$\alpha$, TGF-$\alpha$ only, EGF only nad EGF+TGF-$\alpha$ treated groups, respectively. The nuclear maturation rates in medium with EGF only or EGF+TGF-$\alpha$ were significantly(P<0.01) higher than those non- and TGF-$\alpha$ treated groups. When the oocytes were cultured in media with 10%(v/v) pFF, the nuclear maturation ratesof EGF+TGF-$\alpha$ treated group(75.9%) were significantly(P<0.01) higher than those of non-(59.2%), TGF-$\alpha$ only (64.2%) and EGF only(69.4%) treated groups.
