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