The experiment aimed to evaluate carcass yield, commercial cuts and edible organs of free range broiler chickens fed on rations containing cassava root flour as alternative energy source replacing corn. Three hundred and twenty one-day-old chicks, one half of each sex, were randomly assigned into four treatments represented by isonutritive rations with different levels of cassava root flour (0%, 18%, 36% e 53%). A completely randomized 4x2 factorial design (4 levels x 2 sexes) was used, being four replicates per treatment, with twenty birds each. Avian were slaughtered at 84 days after fasted for six hours and then were bled, unfeathered and eviscerated, being the weights of carcass, cuts and organs recorded to determine their yields. Results showed that replacement of corn for cassava flour reduced significantly birds final weight, but did not affect carcass yield nor cuts or organs relative weight and reduced abdominal fat deposition, being a good alternative to be used when reduction of ration costs compensate the lower final weight of the birds.KEY WORDS: Alternative foods, broilers, carcass yield, cassava.
