A total of 144 one-day-old Arbor Acre broiler chickens were allotted to four dietary treatments in a completely randomized design, to assess growth performance, economics of production, and carcass characteristics of broilers fed diets substituted with dried cabbage leaf residue (DCLR). Four experimental broiler starter diets were formulated which replaced maize at 0% (control, T1), 4% DCLR (T2), 8% DCLR (T3), and 12% DCLR (T4). The birds were randomly allotted to the four treatments having four replicates of 9 birds each in a completely randomized design. The results showed that feeding DCLR to broilers had no effect (P>0.05) on the growth performance. Cost of feed, cost of feed consumed/bird and cost of production significantly increased (P<0.05) across the treatments. Revenue and gross profit were not significantly (P>0.05) different for all the treatments. Live weight and carcass weight of birds feds T4 compared favorably with the control diet. Dressing percentage increased for the substituted diets, with the highest weight observed in T4. The breast, drumstick and back significantly (P<0.05) increased in birds fed T2. The liver of birds fed T4 compared favorably with the control. It was observed that birds fed the substituted diets elicited better carcass characteristics compared to the control diet. It can be concluded that DCLR can be substituted up to 12% in a practical broiler diet, improve carcass characteristics, and can mitigate environmental hazards in communities where cabbage residues are abundant.
