The aim of this study was to evaluate the longissimus muscle area (LMA), fat thickness (FAT), and meat quality traits of Nellore bulls with different expected progeny difference for post-weaning growth (EPDg). Fourty-three Nellore bulls (20 months old, 410±40 kg of mean body weight), were distributed in a completely randomized design and divided into two groups according EPD, high and low. After 120 days on feed, the animals were slaughtered, and 24 h after slaughter carcasses were ribbed at 12^th rib level for LMA and fat thickness measurements. In addition, a Longissimus sample was taken for color, cooking loss and Warner-Bratzler shear force analysis. The EPD group did not alter LMA, BFT and meat quality attributes. Therefore, it can be concluded that selection for different growth rates does not affect carcass traits and meat quality of feedlot finished Nellore young bulls.
