The present research was aimed to evaluate the effect of different inclusion levels of tilapia industrial filleting waste (TM) on protein (PDR) and fat deposition rate (FDR) in broilers chicken breast and legs (thigh and drumstick), slaughtered at 42 days of age. Four hundred and eighty chickens were used in a completely randomized design with five treatments, six replicates and sixteen birds per experimental unit. The treatments consisted in five inclusion levels (0, 2, 4, 6 and 8%) of TM. The experimental diets were isocaloric and isonutritives, following the nutritional requirements recommendations for stages 1 to 21 and 22 to 42 days old for broilers chickens. No influence (P>0.05) for inclusion levels of TM on PDR and FDR in the poultries breast and legs (thighs and drumsticks). According to the results, the inclusion of 8% of tilapia industrial filleting waste in broiler feeding did not affect the parameters of protein and fat deposition rate in broilers chicken carcass.
