Livestock Antibiotic Stewardship and Animal Welfare

Antibiotic overuse in livestock farming contributes to antimicrobial resistance while masking welfare problems. Good stewardship means treating disease promptly while reducing prophylactic and growth promotion uses.

Key Facts

Approximately 73% of globally consumed antibiotics are used in animals, primarily food-producing species
Prophylactic antibiotic use to prevent disease enables high-density farming systems that would otherwise be unsustainable
Antimicrobial resistance is a global health emergency — resistant bacteria from farms enter human food chains
The EU banned growth-promoting antibiotics in 2006 and prophylactic use in 2022
Denmark reduced antibiotic use in pigs by 60% without significant production losses through improved management
Under-treatment of bacterial disease in livestock causes suffering — stewardship means appropriate treatment, not no antibiotics

Welfare Considerations

Antibiotic stewardship intersects with animal welfare in complex ways. Prophylactic antibiotics have been used to enable farming systems with such poor welfare conditions that disease would be inevitable without chemical support. Removing these antibiotics without improving housing conditions could increase disease suffering. However, continued prophylactic use enables systems whose welfare problems would be more visible and economically unsustainable without pharmaceutical support. The welfare-optimal path involves both reducing unnecessary antibiotic use and improving the underlying welfare conditions that drive disease pressure — better housing, lower stocking densities, improved management, and genetic disease resistance. Curative use when animals are genuinely ill is essential welfare practice; prophylactic use to enable poor conditions is ethically problematic.
