  1. NSCorrelation not significantly different from zero
  2. Model 1 = Base model, Model 2 = model with heterozygosity, Model 3 = model with heterozygosity within breed/line, Model 4 = model with expected heterosis level
  3. The highest predictive ability within each line is marked as follows: † line 1, § line 2, # = F1. If no correlations are marked within line, all correlations were equal. Significant differences are not taken into account for these indications
  4. aW21 = 21 days weight in kg, W150 = 150 days weight in kg, BF100 = backfat at 100 kg measured on live animals in mm, LD100 = loin depth at 100 kg measured on live animals in mm, A40 = age at 40 kg, DTP = days from 40 to 120 kg, TFI = total feed intake from 40 to 120 kg in kg (i.e. feed intake per 80 kg live weight gain), LMP = lean meat percentage, DP = dressing percentage (slaughter weight/live weight), IMF = intramuscular fat percentage measured in the laboratory, PHL = pH of loin, DRIP = drip loss is the percentage loss of water from a piece of loin muscle between 96 h post mortem to 120 h post mortem, LB1 = live born first parity
  5. bAlways less than 300 animals with observations for the trait in F1
  6. c,d,eDifferences in superscript letters within row indicate significant differences at P < 0.05. Models 3 and 4 are only comparable to each other within line
