An experiment was conducted to determine the value of a mixture of sun-dried cassava tuber meal (C), brewers' dried grains (B), and palm oil (P) (CBP-mix) based diets with a view to determine its optimal dietary maize replacement levels in broiler starter and finisher diets, its effects on serum biochemistry and carcass characteristics of broilers. Sun-dried Cassava tuber meal (C), Brewers' dried grains (B) and Palm oil (P) were mixed in ratio 60:35:5 respectively. A total of 120 day old broiler chicks were allotted to 4 dietary treatments, in a completely randomised design, containing 0%, 15%, 30% and 45% CBP-mix replacement levels for maize. At the end of the experiment data collected were subjected to one way analysis of variance using SPSS package version 17. All the carcass parameters measured except for drumstick were significant (P< 0.05). The birds on control performed significantly better (P<0.05) than those on CBP-mix diets in terms of live, carcass and thigh weights. Diet 3 (30% CBP-mix) however had the highest dressing percentage, breast muscle and liver. All the serum biochemical parameter showed significant difference (P<0.05). The highest value of Albumin and total protein recorded for birds in diet 4 (45% CBP-mix) suggests high quality of protein while the highest creatinine for birds on diet 1 suggests muscular wastage. Conclusively, diet 3 (30% CBP-mix) was recommended considering dressing percentage, breast and liver weights. Incorporation of these levels of CBP- mix in the diets of broilers does not have any negative effect on the carcass characteristic and serum biochemical profile of the birds.
