Abstract An experiment was conducted to determine the performance of Japanese quail on graded levels of sweet potato (0%, 11%, 22% and 33%) in treatment 1 (T1), treatment 2 (T2), treatment 3 (T3) and treatment 4 (T4), respectively. Ninety six quail birds were allotted to the four treatments (T1, T2, T3 and T4) in a Completely Randomized Design. The experiment lasted 8 weeks. Results showed that feed intake and egg weight were significantly (P<0.05) affected by the treatments. Feed intake was highest in T3 (39.42 +1.24g), followed by T2 (36.36+1.24g) and T1 (35.88+1.24g) and the least was in T4 (32.14+1.24g). Egg weight was highest and same in T4 (12.58+0.693g), T2 (12.54+ 0.693g) and T1 (11.83+ 0.693g) with the least in T3 (9.46+0.693g). There was depression in egg production in T3, therefore T2 is recommended for farmers. Keywords: Crude protein requirement, egg production, egg weight, feed intake, sweet potato meal.
