  1. †= 0.1, * = 0.05 and ** = 0.01 chromosome-wide significance level.
  2. 1REI = residual energy intake; ADEI = average daily energy intake; APD = average protein deposition; ALD = average lipid deposition; FCR = feed conversion ratio; TNE = total nitrogen excretion; ADNE = average daily nitrogen excretion; NEWG = nitrogen excretion per weight gain; BF = backfat thickness.
  3. 2Percentage of variance explained by the QTL calculated as the proportion of residual sum of square from the full model divided by the residual sum of square from null model (excluding QTL effect).
  4. 3Estimated additive, dominance or imprinting effects and their standard error.
