dc.description.abstract The goal of this paper is the optimization of the 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. There were analyzed the following traits: (C. Drăgănescu, 1979) body weight at the age of 182 months (BW), (H. Grosu, S. Lungu, V. D. Kremer, 1997) meat percent in empty body (MPB); (L.N. Hazel, 1943) daily average gain between 0 - 182 month age and (ADG); (C. R. Henderson, 1963) average daily gain on empty body (ADGB). MPB trait was included in each objective (index). The six indices were: (C. Drăgănescu, 1979) MPB + BW; (H. Grosu, S. Lungu, V. D. Kremer, 1997) MPB + ADG; (C. R. Henderson, 1963) MPB + ADGB; (C. R. Henderson, 1963) MPB + BW + ADG; (Ge. Movileanu, 2008) MPB + BW + ASDGB and (Şt. Popescu - Vifor, 1990) MPB + BW + ADG + ADGB. The genetic parameters were computed using the REML 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 (ÄH) and the genetic progress for each trait (ÄGi ). The best index was the last, which included all traits. Its parameters were: 1,087 (rHI); 2,144 (ÄH) and 3,35% (ÄG for MPB) en_US
