Table 1 Variance components (herd variation, polygenic additive genetic variation and residual variation), intra-herd heritability and proportion of variance due to herd for the un-adjusted β-LG content (wt/wt%) and the adjusted β-LG contents

From: Characterizing a region on BTA11 affecting β-lactoglobulin content of milk using high-density genotyping and haplotype grouping

  Un-adjusted β-LG content Adjusted β-LG content

  1. Un-adjusted β-LG content is the β-lactoglobulin content as fraction of the total protein fraction
  2. β-LG1 is β-LG adjusted for the genotype of the cows for Q-Tag SNP1
  3. β-LG2 is β-LG1 adjusted for the genotype of the cows for Q-Tag SNP2
  4. β-LG3 is β-LG2 adjusted for the genotype of the cows for Q-Tag SNP3
  5. β-LG4 is β-LG3 adjusted for the genotype of the cows for Q-Tag SNP4
  6. β-LG5 is β-LG4 adjusted for the genotype of the cows for Q-Tag SNP5
