Abstract: One hundred and eighty 14-day-old noiler chicks of average body weight range of 187-190 g were used in a 16-week feeding trial to assess the effects of toasted bambara nut sievate-yam peel meal composite (TBNS-YPMC) mineral content and impact on carcass traits and bone morphometry. Birds were divided in two groups of 90 individuals. Each group was sub-divided in three sub-groups of 30 birds and replicated thrice with 10 birds. The experiment was a 2 × 3 factorial arrangement. The first group was offered diets: T1, 0; T2, 20; and T3, 40% of TBNS-YPMC replacing maize, respectively without Lactic Dry® (LD). The second group received the same diets with LD. Results showed that TBNS-YPMC had good mineral content: phosphorus, calcium for the second group. Birds fed 20% TBNS-YPMC and diets with LD had performed with 2.23 ± 0.11 kg de-feathered weight. Eviscerated (1.95 ± 0.10 kg) and carcass weights (1.80 ± 0.08 kg) were performed for bird fed control diet without LD and 20% TBNS-YPMC with or without LD. Birds fed 40% TBNS-YPMC without LD and the control diet with LD had improved (4.25 ± 0.14 ppm) in calcium. Phosphorus was improved (2.23 ± 0.03 ppm) in birds fed 40% TBNS-YPMC without LD and diets containing 0 and 40% TBNS-YPMC with LD. All birds had improved magnesium, zinc, and iron except those fed control diet without LD. It was concluded that TBNS-YPMC contains calcium, phosphorus, magnesium, iron, zinc, potassium and manganese. The study recommends 40% TBNS-YPMC replacement for maize in noiler diets with LD to improve de-feathered, eviscerated, carcass weight and bone mineral contents.
