Table 2 Estimates of heritability from single-trait pedigree-based animal model analyses for early (e) traits recorded at 26-28 weeks of life and for late (l) traits recorded at 42-46 weeks

  1. 1 Standard errors of heritability were between 0.02 and 0.03; early (e) traits recorded at 26-28 weeks of life: egg production (ePD); age at sexual maturity (eSM); shell quality (ePS); weight of first 3 eggs (eE3); color of first 3 eggs (eC3); egg weight (eEW); albumen height (eAH); egg color (eCO); and yolk weight (eYW); late (l) traits recorded at 42-46 weeks: body weight (lBW); egg production (lPD); egg weight (lEW); albumen height (lAH); egg color (lCO); and yolk weight (lYW)
