Data were collected on 3844 Nellore cattle reared under pasture conditions in two different farms in southwestern Brazil, where 1889 of them were measured by ultrasound for carcass traits and where 674 bulls finished in a feedlot for 90 to 120 days and slaughtered around 24 months of age. The data were analyzed to determine the association of genetic markers (DNA single nucleotide polymorphisms) with traits economically important for the Brazilian beef business. Growth traits considered were birth weight, weaning weight, yearling weight measured at 18 months, weight gain after weaning, visual scores for carcass conformation, finishing, and muscle. Carcass traits, measured by ultrasound, were ribeye area, backfat and fat depth at rump. Read more. . .
