  1. NC Not converge
  2. aEstimates of heritability (diagonal), and genetic (above diagonal) and phenotypic (below diagonal) correlations
  3. bPED, porcine epidemic diarrhea
  4. cAB, Abortion; TB, Total number of piglets born; NBA, Number of piglets born alive; SB, Number of stillborn piglets; MUM, Number of mummified piglets; NBD, Number of piglets born dead; PROP, Proportion of piglets born dead; NW, Number of piglets weaned
  5. dAB was treated as a quantitative variable and was assumed to have no residual covariance when estimating correlations between this and other traits
