  1. 1T4/4: trait with ha2 = 0.04, hm2 = 0.04 and lit2 = 0.04, T2/4: ha2 = 0.02, hm2 = 0.04 and lit2 = 0.04; T2/2: ha2 = 0.02, hm2 = 0.02 and lit2 = 0.02, in liability scale
  2. 2G_all: all pigs were genotyped; G80_ran: 80% of pigs randomly selected from the whole population were genotyped; G_alive: only alive pigs (80%) were genotyped; G_none: no pig was genotyped
  3. 3LM linear model, LG logit model, PM probit model
  4. 4a: direct additive genetic effect; m: maternal additive genetic effect
  5. a,b,c,dMeans in column for the same trait without a common superscript differ significantly (P < 0.05), according to paired t test
