The aim of this paper was to evaluate economical viability and steers performance in grazing receiving supplements with increasing levels of crude protein in the rainy season and its correlation with the pasture's composition. The test animals were 21 not castrated steers supplemented with mineral supplement and multiple supplements with 20% and 40% of crude protein and heavy at the beginning and the end of the experiment, after being submitted to fasting from liquids and solids for 14 hours. For analysis of the economic viability was used the difference between the Total Revenue and Total Cost. The protein supplementation didn't influence of the animals performance in grazing. The average daily gain of animals was 0.849 kg. The content of crude protein in the cell wall was negatively correlated with animal performance, and the structural characteristics of the pasture just the mass of forage showed a strong and positive correlation. This activity in the studied period presented economic viability when considered return on capital of 8% a year.
