  1. ADG0 = average daily gain before infestation; ADG1 = average daily gain during the first infestation; FEC1 = faecal egg count during the first infestation; FEC2 = faecal egg count during the second infestation; SNPED refers to estimates obtained by using the joint pedigree and molecular information relationship matrix (SNPED model); PED refers to the pedigree-only relationship matrix (PED model); the correlations between ADG0 and ADG1 were much more sensitive than others to the starting values used for the estimation and to re-sampling, and are not presented; heritabilities are on the block diagonal, genetic correlations are above the diagonal and phenotypic correlations are below the diagonal; standard errors of the estimates are between brackets; superscript * marks the estimates that were significantly different from 0.
