Antibiotic use in animal production drives antimicrobial resistance threatening both human and animal health. Stewardship programs that reduce antibiotic use also often improve animal welfare.
Antibiotic stewardship and animal welfare improvement are deeply interconnected. Prophylactic antibiotic use in crowded, stressful, poorly managed production systems is a welfare problem indicator as much as a resistance driver: it reflects that animals are living in conditions that compromise their immune systems. Addressing the root causes through welfare improvement reduces both antibiotic need and animal suffering simultaneously. Systems that achieve low antibiotic use through improved welfare management rather than untreated disease demonstrate that welfare and AMR goals are complementary rather than competing.
