However, increasing productivity of swine herds has been increasingly sought, and allied to this, animal nutrition work has been intensified to determine both protein and energy requirements, to better meet material requirements, genetic resources in the field. The objective of this study was to evaluate the influence of different energy levels on Piau castrated male pigs in the finishing phase of 70 to 90 kg body weight. Twenty castrated males with initial mean body weight of 71 ± 0.72 kg were used, distributed in four treatments with decreasing levels of metabolizable energy in the diets (3,230, 3,000, 2,770 and 2,540 kcal of metabolizable energy/kg ration) and five replications per diet,each animal was considered an experimental unit. The diets used were formulated to meet the nutritional needs of animals, varying the value of metabolizable energy through the amount of corn, soybean meal and wheat bran.Statistical analyzes were performed using analysis of variance and regression, and the F and Tukey tests with a significance level of 5% probability, using the R-Project version 2.13.1 for Windows software. There was a significant effect (P <0.05) on the performance of the piglets as a function of energy: protein ratio for Piau castrated male finishing pigs for period weight gain, feed intake and feed conversion.
