The widespread use of antibiotics in livestock production raises both public health concerns about resistance and animal welfare concerns about the underlying conditions making antibiotics necessary.
Antibiotic use in livestock is simultaneously a public health issue and an animal welfare indicator. When antibiotics are used to prevent disease outbreaks in densely housed animals, it often signals that underlying conditions are causing disease pressure. Rather than treating the system that generates disease, antibiotics maintain productivity while welfare problems persist beneath the surface. Genuinely improving animal welfare — through better housing, lower stocking densities and adequate nutrition — reduces the need for antibiotics. This connection between welfare improvement and antibiotic stewardship creates aligned incentives for reform.
