40 piglets were used to evaluate the zootecnic and bioeconomical performance which contained differente levels of crude protein (CP) in21 to 42 days old piglet ration. The experiment was designed in aleatory blocks with four treatments and five repetitions. The experimental unit consisted of two animals (female or male). The treatments used were 17, 19, 21 and 23% CP inclusion diet. The rations were in the same quantity of lysine (1.4%) and metabolizable energy (3.265 kcal/kg). According to the obtained results, there were linear effect for average daily gain, food conversion, utilization and daily crude protein intake. However, the best experiment response was in the group 23% of CP. The crude protein diet bioeconomical performance addition reduced the piglet kilogram cost.
