Abstract: A total of 144 day old straight run starbro broiler chicks were fed ad libitum up to 42 days of age on 3 different iso-nitrogenous and iso-energetic diets formulated by replacing dietary fish meal (FM) partially to completely by broiler offal (BO). In 3 diets 0, 4 and 8% BO replaced equal amount of FM to compare growth performance, profitability and meat yield among 3 diets. At 42 day of age, live weight increased almost linearly with increasing levels of dietary BO (P<0.01). Feed consumption was also positively correlated with BO concentration in diet. Feed conversion also improved on increasing levels of dietary BO (P<0.01). But survivability had little relation with dietary BO. Profitability of broiler rearing increased at increasing concentration of BO in diet. Meat yield also increased as BO replaced the dietary FM. It was concluded that replacement of costly conventional dietary FM by unconventional BO could increase performance of broilers with increased profitability and meat yield.
