Abstract This study was designed to assess the effects of partial substitution of roasted soybean seed with sweet potato (Ipomoea batatas) leaf meal (SPLM) on growth performances and carcass components of broiler chickens. The experiment was a completely randomized design consisting of five dietary treatments replicated four times with ten chicks each. The control diet (treatment 1, T1) contained roasted soybean seed as the major protein source without SPLM and treatment diets containing SPLM at the levels of 30 g/kg (treatment 2, T2), 60 g/kg (treatment 3, T3), 90 g/kg (treatment 4, T4) and 120 g/kg (treatment 5, T5) by partially substituting the roasted soybean seed in the control diet. The results indicated that the body weight gain in chickens reared in T1 was (p<0.01) higher than those fed on T3, T4 and T5 diets. The individual feed intake in chickens reared in T1 was (p<0.001) higher than those fed on other treatment diets. The feed conversion ratio (kg feed/kg gain) of chickens fed on T1 was (p<0.05) lower than those reared in T4 and T5 diets. Chickens fed with T2 diet had numerically higher values of slaughter, dressed carcass and breast than those reared in T4 and T5 diets. It can be concluded that the partial substitution of roasted soybean seed with sweet potato leaf might be economically feasible feeding strategy of broiler chickens in smallholder poultry farm settings.
