In the experiment I, 24 were used, crossbreed entire males swines, with initial body weight of 18.28 ± 0.7 kg were distributed in a randomized complete block design, consisting of three treatments (protein sources), eight replicates and one swine per experimental unit (metabolism cages). In the experiment II, 1,843 were used, crossbreed entire males and females piglets, with initial body weight of 6.79 ± 0.90 kg were distributed in a completely randomized experimental design, in a 2 x 3 factorial arrangement (two sexes and three protein sources), 13 replicates of 46 to 53 animals per experimental unit. The different protein sources were: Fish Meal - FM, Soybean Protein Concentrate - SPC and Soybean Meal - SM, being the control diet. In the pre-starter II and starter phases, the blood was collected from 235 animals, for the determination of plasma urea and glucose. For the digestibility assay, no differences (p>0.05) were obtained between the protein sources for the apparent digestibility coefficients. There was an effect (p 0.05) of treatment for the other variables of the nitrogen balance, neither for the protein balance. In experiment II, there was no interaction effect (p>0.05) of protein sources and sex in the performance in the nursery phases. There was a difference (p0.05) in the pre-starter II and starter phases. There was a difference (p0,05) entre as fontes proteicas para os coeficientes de digestibilidade aparente. Houve efeito (p0,05) de tratamento para as demais variáveis do balanço de nitrogênio, nem para o balanço proteico. No experimento II, não houve efeito de interação (p>0,05) de fontes proteicas e sexo sobre o desempenho nas fases de creche. Houve diferença (p0,05) nas fases pré-inicial II e inicial. Houve diferença (p
