An experiment was conducted to test four different mixing ratios of soyabean meal (SBM) and poultry offal meal (POM) on the performance and carcass evaluation of cockerel chicks. The mixing ratios of SBM: POM were 100:0, 75:25, 50:50 and 25:75. Feed intake and weight gain were affected (P<0.05) by the diets. Feed intake significantly increased as the proportion of poultry offal meal increased to 25 percent. The increase in the proportion of poultry offal meal above 25 percent did not result in corresponding feed intake for bird. Birds fed at soya bean meal: poultry offal meal 75:25 recorded the highest feed intake and weight gain i.e.70g/bird/day and 29g/bird/day respectively. Feed:gain was inversely related to substitution levels of SBM to POM. Nutrients retention was significantly (P<0.05) different among dietary treatments. Protein retention was not affected as the proportion of poultry offal meal increase up to 50 percent. However, further increase in the proportion of poultry offal meal significantly (P<0.05) decreased protein retention. Fat retention was directly related to increasing levels of poultry offal meal. Mortality and carcass quality were not affected (P<0.05) by the dietary conditions. Cost/kg of cockerel chick's diets decreased as the level of poultry offal meal increased. Generally, SBM:POM 75:25 gave the best performance considering the aggregate of all the criteria.
