The purpose of this study was to estimate the genetic parameters for carcass traits of longissimus muscle area (LMA), backfat thickness (BF) and rump fat thickness (RF), measured by ultrasound in Polled Nelore cattle raised in the Cerrado biome. The data set was obtained from bovines Polled Nelore, proceeding from participant farms of the Nelore Brazil Program of the National Association of Breeders and Researchers, raised on pasture, from the Brazilian states that have the largest continuous areas of the Cerrado. Heritabilities were estimated by Gibbs Sampling using the MTGSAM software (Multiple Trait using Gibbs Sampler under Animal Model). The heritability estimates were 0.30, 0.17 and 0.25 for LMA, BF and RF, respectively. The results indicate that carcass traits have high genetic variability and should be included in breeding programs.
