Beyond day-one passive transfer, does continuing to supplement with colostrum replacer actually change health outcomes down the line? This study evaluated how colostrum replacer supplementation affected disease occurrence, antibiotic therapy needs, and overall performance in pre-weaned calves. For producers deciding whether supplementation is worth the ongoing cost past the first feeding, this looks at the real-world payoff, not just antibody numbers.
