The objective of this study was to evaluate animal performance, carcass characteristics and costs for pigs fed diets adjusted to Brazilian conditions, through the model InraPorc®. We used 36 barrows and 36 females, during the growing and finishing in a completely randomized design. The treatments were control diets and diets adjusted for both males and females. The feeding program and the animal profile were added to the model parameterization and define strategies and nutritional feed in the diets adjusted. The performance and carcass traits were not affected by treatments. The average cost to feed the animals that received the control diet was higher in 3.4% and 2.4% for the males and females respectively. Comparing the diets, the average cost to feed the animals that received the control diet was 2.9% higher. Net income was R$0.19 and R$0.66 higher for males and females which received the diet adjusted, respectively. Diets adjusted through InraPorc® for the growing and finishing pigs did not influence the performance and carcass traits, however reduced feed costs which generates higher net production.
