  • Line-type and experimental group were main factors whereas body mass was a covariate. C, food consumption; DFI, digestible food intake

  • 1 The value of 95% CI calculated for heritability of food intake h2=0.78 (Bachmanov et al., 2002)

  • 2 The value of 95% CI calculated for heritability of organ masses h2=0.4 (Schlager, 1968)

  • 3 The value of 95% CI calculated for heritability of activity of CS h2=0.08 (Garland et al., 1990)
