The link between farm animal welfare, antibiotic use, and antimicrobial resistance connects animal welfare to one of the most significant global health threats.
The welfare-AMR connection is one of the strongest arguments for farm animal welfare improvement as a public health intervention. Animals in high-stress, overcrowded conditions with compromised immune function require more antibiotics to prevent disease. Improving welfare conditions - space, enrichment, proper nutrition, reduced crowding - directly reduces antibiotic need. This creates a powerful policy argument that welfare improvement serves not just animal interests but human health. One Health frameworks that connect animal welfare, antibiotic stewardship, and human AMR outcomes provide the integrated policy rationale for welfare investment that goes beyond animal welfare advocacy alone.
