Not all proteins in colostrum carry equal weight when it comes to calf health outcomes. This study used a proteomics approach to rank colostrum and milk proteins by their relative importance, moving past the assumption that IgG is the only protein worth tracking. For anyone thinking about colostrum quality holistically, this gives a data-backed hierarchy of what actually matters most.
