  1. Heritability estimates (diagonal) and phenotypic (upper triangle) and genetic correlations (lower triangle) with standard errors (SE) from the trivariate animal model for body weight at 0 dpi (BW0), average daily gain and viral load from 0 to 21 and 0 to 42 dpi (ADG21, ADG42, VL21 and VL42), respectively
  2. Correlations between ADG21 and VL42 were not calculated, since VL is expected to impact ADG and not the other way around
