1: SE = standard error. 2: LHCW = left half-carcass weight, CL = carcass length, DCh = depth of chest, HL = hind-limb length, HP = hind-limb perimeter, CC = carcass compactness, CS = conformation score, CS = EUROP classification scales for conformation (from P − = 1 to 15 = E +), FS = fat cover classification (from 1 = low to 5 = very high). 3: Means with different letters (a, b) are significantly different (SNK p < 0.05). 4: ns = non-significant.
