Animal Welfare Impacts of Antibiotic Resistance Management

Efforts to curb antibiotic use in livestock to combat antimicrobial resistance sometimes conflict with individual animal welfare by limiting access to treatment for sick animals.

Key Facts

Over 70% of global antibiotic use by mass occurs in livestock, primarily for growth promotion
The EU banned prophylactic antibiotic use in animals as of January 2022
Denmark reduced antibiotic use in pigs by 50% over two decades without reducing production
Restricting antibiotics without improving husbandry can increase animal suffering from untreated disease
Metaphylactic treatment (group treatment when one animal is sick) is contested in resistance and welfare terms
Veterinary prescription requirements for antibiotics now apply in most high-income countries

Welfare Considerations

Antibiotic stewardship in livestock is essential for global health, but must be implemented alongside improved husbandry to avoid welfare trade-offs. Prohibiting routine antibiotic use in densely stocked, disease-prone systems without improving the underlying conditions creates a situation where sick animals may go untreated. The most effective approach combines antibiotic restrictions with enhanced biosecurity, lower stocking densities, improved nutrition, and strong veterinary oversight to treat genuinely sick animals while preventing the need for mass prophylaxis.

What You Can Do

Support policies that pair antibiotic restrictions with mandatory husbandry improvements
Choose animal products from lower-stocking-density systems where disease risk is lower
Advocate for strong veterinary oversight of antibiotic use rather than blanket bans
Support research into alternatives to antibiotics such as phage therapy and vaccines
