¹Estimated theoretical DGV accuracy (rPEV) calculated based on diagonals of inverse of coefficient matrix in GBLUP20; ²association evaluated by the correlation between individual DGV accuracy and each measure of relatedness of testing set animals with training set, calculated either as the maximum relationship (maxr) or as the average of the top 5 (ave5), 10 (ave10), 20 (ave20) or 50 (ave50) relationships between each testing animal and all training set animals; ³Averages of relatedness of testing set animals with training set, evaluated through maxr or ave5; *WG = 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].
