摘要
The aim of this study was to evaluate the differences between lineages of Nellore breed for carcass and meat quality traits. Thirteen lineages of Nellore breed were evaluated from data of carcass and meat quality of 516 animals for estimating the expected progeny difference for hot carcass weight, rib eye area, fat thickness, marbling and shear force values at 7, 14 and 21 days of ageing. The founder Golias reached the better values of expected progeny difference for hot carcass weight (+1.20kg), rib eye area (+0.88cm), marbling (+3.47un) and average shear force (-0,09kg), and Akasamu the better value for fat thickness (+0.05mm). The differences between lineages of Nellore breed found in this study couldbe used to select sires for genetic improvement of carcass and meat quality traits in Brazilian beef cattle herds.
