A feeding trial of 6 weeks was conducted to determine the effect of including rice offal supplemented with natuzyme on the performance of growing Japanese quails. One hundred and eighty 2 –week old quails of mixed sexes were randomly allocated to four diets in a completely randomized design. The quail chicks were allocated one of four diets containing either 0 (Control), 5, 10, and 15% of rice offal. The diets were isonitrogenous (25% CP) but decreased in energy levels from 2,779.32 (Diet A), 2,747.73 (Diet B), 2,715.54 (Diet C) to 2,683.54kcal/kg ME (Diet D). Each diet was replicated thrice with feed and water given ad libitum. Feed intake was significantly lower (p<0.05) on diet A (20.64g/bird) than on diets C (23.48) and D (24.08g/bird/day). Feed conversion ratio was significantly better (p<0.05) on diet A (5.87) than on diets B (7.70), C (8.36) and D (7.95) respectively. Feed cost/kg gain was significantly (p<0.05) better on diet A (N532.65) than on diets B (N666.75) and C (N688.92) only. Water intake (34.24, 34.93, 34.77 and 37.71ml/bird/day) and weight gain (3.53, 2.93, 2.83 and 3.05g/bird/day) did not differ significantly (p˃0.05) across the diets. The diet with 5% rice offal was similar in feed intake and weight gain to the control and is recommended.
