During the PMI, the calves acclimate to their new environment, stress levels decline, feed intake increases and immune suppression drops off, in part due to immune response to existing pathogens.
How Metaphylaxis Controls Disease

Numerous controlled and blinded trials have shown that in high-risk calves arriving at feedlots or stocker operations, mass treatment with an antibiotic significantly reduces BRD sick pulls and mortality.
