An experiment was conducted to study the response of broiler to diet dilution during the finishing period. Sixty 29-day-old commercial Avian male broiler chicks were assigned to two groups randomly, with 30 broilers each. Birds were offered a conventional finishing diet or with 10% dilution diet with ground rice hulls from 29 to 49 days of age. The result showed that there were no significant differences between the effects of diet dilution and the control on final body weight, growth rate and feed conversion efficiency. Diet dilution led to a reduction in abdominal fat weight, whereas carcass and breast muscle weight were not affected.
