Conteúdo: | The objective was to obtain estimates of additive genetic changes in weight gain (WG), carcass conformation (WC), precocity (WP), muscling (WM), and body size (WS) at weaning and weight gain (YG), carcass conformation (YC), precocity (YP), muscling (YM), body size (YS), longissimus muscle area (LMA), subcutaneous fat thickness (FAT), and scrotal circumference (SC) post-weaning. The additive genetic change in SC did not differ from zero (P > 0.05). Annual additive genetic changes in WG, WC, WP, WM, WS, YG, YC, YP, YM, YS, LMA, and FAT were all favorable, corresponding to 1.8, 3.6, 3.6, 4.0, 3.1, 2.3, 3.5, 1.4, 2.3, 2.7, 0.8, and 1.3% of the phenotypic average (P < 0.01), respectively. These high estimates indicate that the genetic improvement program was effective to promote desirable additive genetic changes in most evaluated traits.
