Abstract Large amounts of waste, including dead birds, manure, and poultry litter, are produced by the poultry industry. Poultry waste should be disposed of properly to avoid major pollution and health risks. Composting litter and dead birds could be an option to recycle the waste and use in poultry feed. A study was conducted to investigate the effects of feeding composted poultry waste on the organoleptic qualities and compositional profile of the meat of broiler chickens. A total of 300 day-old broiler chicks (500-Cobb) were randomly allocated to five treatment groups replicated six times with 10 birds each, under a completely randomized design (CRD). Five iso-caloric and iso-nitrogenous diets including composted poultry byproducts at concentrations of 0, 2.5, 5, 7.5, and 10% were fed ad libitum to the birds from day 0 to day 35. The sensory grading and meat composition profile of 500 Cobb broiler chickens were tested at 35 days of age. The findings showed that there were no variations in the sensory profiles of the meat from birds given various diets (P>0.05). Although the results were somewhat lower for the chicks fed compost-containing diets than for the control group, this difference was deemed to be insignificant (P>0.05). Similarly, there were no variations in the compositional profile values of the meat between meat from birds fed various diets (P>0.05). These findings imply that broiler chickens may be raised on diets containing up to 10% poultry byproduct compost without any negative impacts on the meat's sensory quality or composition. Additionally, using compost into broiler diets may help to lower the cost of feed. Resumo Grandes quantidades de resíduos, incluindo aves mortas, esterco e cama de frango, são produzidas pela indústria avícola. Resíduos de aves devem ser descartados adequadamente para evitar grandes riscos de poluição e saúde. A compostagem de lixo e aves mortas pode ser uma opção para reciclar os resíduos e usá-los na alimentação de aves. Um estudo foi conduzido para investigar os efeitos da alimentação com resíduos de aves compostados nas qualidades organolépticas e no perfil de composição da carne de frangos de corte. Um total de 300 pintos de corte de um dia (500-Cobb) foram alocados aleatoriamente em 5 grupos de tratamento, replicados 6 vezes com 10 aves cada, sob um delineamento inteiramente casualizado (CRD). Cinco dietas isocalóricas e isonitrogenadas incluindo subprodutos compostados de aves nas concentrações de 0, 2,5,
