Total serum proteins concentration (TP) is frequently measured in calves to evaluate adequacy of passive transfer of immunoglobulin G (IgG) from colostrum. However, calves fed some commercially available colostrum-derived colostrum replacers (CR) may have lower serum TP at equal IgG concentrations as compared to calves fed maternal colostrum (MC). This can be due to removal of some proteins during manufacturing of CR. The objective of this study was to determine the linear relationship between TP and IgG at 22 to 28 h after birth for CR and MC.
