ABSTRACT
The objective of this study was to verify the performance and carcass quality of pigs from four genetic lines and to correlate these data with the number and diameter of muscle fibers. A total of48 pigs were used and distributed into four treatments: high-lean commercial crossbred line; prolificacy commercial crossbred line; (Landrace X Large White) crossbred animals; and undefined genetic line. The experimental design consisted of a complete randomized design with a 4 x 2 factorial arrangement (4 genetic lines and 2 genders). Daily weight gain, daily feed intake and the feed conversion were evaluated. At slaughtering, the carcasses were evaluated and the number and the diameter of the muscle fibers of longissimus dorsi were assessed. The high-lean commercial line presented the greatestnumber of muscle cells (P
