Farm Antibiotic Use and Animal Welfare: Two Issues That Cannot Be Separated

The mass use of antibiotics on farms harms animal welfare by masking disease problems rather than addressing their root causes, while also driving antimicrobial resistance that threatens human and animal health alike.

Key Facts

An estimated 70% of all antibiotics consumed globally are used in food animal production, primarily in intensive systems
Prophylactic (preventive) antibiotic use in groups of healthy animals is now banned in the EU but remains common in other regions
High-density housing, stress, and poor biosecurity are the primary drivers of disease that leads to antibiotic dependence on farms
When antibiotics are withdrawn without improving husbandry, disease rates and welfare problems typically increase significantly
Antibiotic resistance is a growing crisis — resistant infections kill an estimated 1.27 million people annually worldwide
Animals in high-welfare systems with lower stocking densities and better management typically require fewer antibiotics
The link between antibiotic reduction, improved husbandry, and better welfare outcomes is now well-established in research

Welfare Considerations

Antibiotic dependence in livestock farming is both a symptom and a cause of poor welfare. When animals are housed at high densities with inadequate enrichment and ventilation, disease pressure rises and antibiotics become the primary management tool rather than husbandry improvement. This creates a welfare trap: animals remain in conditions that cause suffering, kept alive by drugs rather than genuine welfare improvement. Reducing antibiotic use in a way that actually improves welfare requires investing in better housing, lower stocking densities, and more skilled stockmanship.

What You Can Do

Choose meat, dairy, and eggs from producers certified under antibiotic stewardship programs
Support EU-style policies to ban prophylactic antibiotic use in food animal production worldwide
Advocate for antibiotic use data transparency — producers should publish their usage figures
Support research into alternatives to antibiotics including vaccines, probiotics, and improved housing
Ask fast food and food service companies to adopt antibiotic stewardship policies for their supply chains
Connect antibiotic resistance advocacy with animal welfare messaging to build broader coalitions
Choose lower-stocking-density animal products as a proxy for both better welfare and lower antibiotic use
