Genetic parameters of egg number, egg laying rate and age at first egg1.

1: Heritability is given on diagonal (bold is SNP-based and italic bold is pedigree-based heritability), SNP-based genetic correlations above diagonal and pedigree-based genetic correlations below diagonal. Standard errors of estimates are in parentheses.2: EN1, egg production from 21 to 26 weeks of age; EN2, egg production from 27 to 36 weeks of age; EN3, egg production from 37 to 72 weeks of age; EN4, egg production from 37 to 47 weeks of age; EN5, egg production from 48 to 72 weeks of age; LR, egg laying rate from 25 to 40 weeks of age; AFE, age at first egg.3: NC indicates that the model would not converge.Genetic parameters of egg number, egg laying rate and age at first egg1.
