The goal of this research is the optimization of selection objective in a paternal pig line. For this purpose, we simulated six types of indices, which differ among them in the number of traits. The following traits were analyzed: body weight at the age of 182 months (BW), meat percent in empty body (MPB), daily average gain between 0-182 month age and (ADG), average daily gain on empty body (ADGB). MPB trait was included in each objective (index). The six indices were: MPB+BW; MPB+ADG; MPB+ADGB; MPB+BW+ADG; MPB+BW+ASDGB, and MPB+BW+ADG+ADGB. The genetic parameters were computed using the RFML method. The biologic importance of the traits were estimated on a linear multiple regression. In order to establish the best combination of traits which maximize the expected genetic progress, some parameters were used, as: accuracy of selection, overall genetic progress and the genetic progress for each trait. The best index was the last, which included all traits.
