Forty-eight crossbred Landrace × Large white pigs with an average body weight of 8.5 ± 0.4 kg and aged 2 months were used to evaluate performance and carcass characteristics of pigs fed two diets in which bran from maize or wheat was used as the energy source. A third diet based on whole maize grain was used as a control. Animals in groups of four, balanced for litter, sex and weight were allotted to dietary treatments in a completely randomised design with four replications. Data were collected on feed intake and weight gain for a period of 4 months. A digestibility trial was carried at the end of the feeding trial using two male pigs per treatment while six pigs per treatment were randomly selected for slaughter to determine carcass characteristics. Daily gain averaged 0. 23, 0. 31 and 0. 13 kg/day, for pigs fed maize bran, wheat bran and whole maize diets, respectively. Average feed intake and final body weight were significantly (P < 0. 05) affected by diets. Digestibility of dry matter, crude fibre and calcium were higher (P < 0. 05) for pigs fed maize bran while crude protein digestibility was highest (P < 0. 05) for the pigs fed wheat bran. There were significant differences (P < 0. 05) between the diets in carcass yield, ham, head, trotters and heart weights and also for rib weight, rib eye muscle and other tissues. This study indicates that comparable performance of growing pigs fed cereal bran and full-grain diets are real. © 2012 Springer Science+Business Media B.V.
