  1. Numbers in parenthesis are the standard errors
  2. Bold characters highlight significant \({h}^{2}\), \(r\) and breed effects
  3. Range shows the 5th quantile and 95th quantile, respectively
  4. The natural antibodies are coded as follows: MDP Muramyl dipeptide, KLH Keyhole limpet hemocyanin, IgA Immunoglobulin A, IgG Immunoglobulin G, IgM Immunoglobulin M
  5. N number of analyzed samples
  6. aBreed effects are relative to Swedish Red (SRB)
  7. bVariance components and effects were estimated using a square root transformation
