Sumario:The study evaluated the performance and carcass composition index of Nile tilapia (Oreochromis niloticus) fed with diets containing increasing levels of spray-dried blood meal (SDBM) and vat-dried blood meal (VDBM) and formulated based on digestible amino acids. Two hundred and fifty-two fingerlings were distributed in a completely randomized design, in a (2 x 4) + 1 factorial model, two types of blood meal with four levels of each blood meal in the diet, and a control diet (without blood meal), with four replications. The treatments consisted of soybean meal-based control diet, with 34% digestible protein (DP) and 3,200 kcal of digestible energy kg-1 (DE), plus four diets formulated with SDBM and four diets with VDBM, containing 5, 10, 15 and 20% of each meal in feed, maintaining identical DP, DE, phosphorus, calcium, lysine, methionine, threonine and tryptophan levels as those of the control diet. The results show that it is possible to use up to 15% VDBM in diets of Nile tilapia (O. niloticus) between 5 to 150 g of body weight.
