Inclusion of cassava waste meal inclusion in broiler diets. The objective of this work was to evaluate performance, economic viability and carcass traits of broilers fed with diets containing five inclusion levels (0.0; 7.5; 15.0; 22.5 and 30.0%) of cassava waste meal (FVM). Three hundred sixty one-day-old pullets were used, distributed in a randomized block design experiment with five treatments and six replications, containing twelve birds per box. The parameters evaluated were feed intake, weight gain, feed-to-gain ratio, feeding costs, gross income, gross margin and profitability. Two broilers per replication were slaughtered at 42 days in order to evaluate the weights of carcass, main cuts, offal and total fat for carcass yield determination and to calculate the percentages of cuts, total fat and offal in relation to live and carcass weights. The chest and thigh + drumstick were deboned and their yields calculated in relation to cuts, carcass and live weight. Shinbone color was evaluated. The evaluated performance and economic parameters show no effects from FVM levels. Gizzard weight and yield and shinbone color were linearly affected. Response to meat yield of thigh + drumstick was quadratic. Cassava waste meal can be incorporated in broiler diets in levels of 30%.
