Resumo: The research was conducted at the Department of digestibility Not Ruminants, Department of Animal Science, Federal Rural University of Pernambuco, with the aim of evaluating the use of byproducts protein in diets for Nile tilapia (Oreochromis niloticus) on the parameters of performance and carcass characteristics. Three experiments were performed to evaluate performance of the following byproducts: cane yeast at levels 0, 10, 20 and 30% inclusion (Chapter 2), poultry by-products 0, 6, 12 and 18% (Chapter 3) castor meal 0, 3, 6 and 9% inclusion (chapter 4). The experimental design for all experiments was a completely randomized design consisting of four treatments and six replications in each experiment, we used 144 male fingerlings of Nile tilapia, sexually inverted distributed in 24 polyethylene tanks with a capacity of 80L each, interconnected in a recirculating system with water using biological filter. At the end of each experimental period were evaluated: weight gain, feed intake, feed conversion ratio, protein efficiency rate, survival rate, weight and carcass yield, weight and trunk yield, hepatosomatic index and abdominal fat index. The conditions under which the tests were performed, it can conclude that the best level of spray dried yeast for Nile tilapia is up to 10% for poultry viscera meal is 18% and the inclusion of castor bean bran negatively influences the final weight, weight gain, weight and carcass yield of Nile tilapia.
