  1. 1Accuracies measured as the Pearson’s correlation between direct genomic values (DGV) and deregressed EBV (dEBV) of the bulls in the testing set, r(dEBV,DGV), divided by the average accuracy of dEBV in the testing set; 2Inflation of genomic predictions measured by the slope of the regression of dEBV on DGV, b1(dEBV,DGV); The estimates of empirical accuracies and inflation refer to the forward prediction design; 3WG = weight gain from birth to weaning (about 205 days of age); Cw, Pw, Mw, Nw = visual scores taken at weaning for carcass conformation, finishing precocity, muscling and navel, respectively; PWG = weight gain from weaning to yearling (about 550 days of age); Cy, Py, My, Ny = visual scores taken at yearling for carcass conformation, finishing precocity, muscling and navel, respectively; SCaw = scrotal circumference adjusted for age and weight; BW = birth weight; GL = gestation length; WI = weaning index, composed by traits evaluated at weaning; FI = final index, composed by traits evaluated at weaning and yearling (FI) [See Additional file 1 for more details].
