This study aims to investigate the effects of including rice bran and hominy feed in growing-finishing diets on growth performance, digestibility and carcass quality. A total of 160 pigs of 30.0 ± 3.77 kg body weight were allocated into two dietary treatments: a conventional diet (C) or a diet containing cereal by-products (S). The level of rice bran and hominy feed in the S diet was 60 and 120 g/kg during the growing phase (30-70 kg BW) and 80 and 125 g/kg during the finishing phase (70-110 kg BW). Pigs’ weight and feed intake was controlled on days 1, 51 and 90. At slaughter some carcass characteristics were recorded. No significant differences were observed between groups in ADG, ADFI and FCR. However, animals fed the S diet showed a higher protein and crude fat digestibility compared to those fed the C diet (P<0.07). At slaughter, no differences were found between treatments in carcass yield, lean meat content, meat pH, meat and fat colour and fat depth at gluteus medius. Thus, the inclusion of increasing levels of rice bran and hominy feed in pig diets led to no significant effects on growth performance and carcass quality although modified nutrient digestibility
