Pig Antibiotic Resistance and Welfare Stewardship

How antibiotic use in pig farming contributes to resistance and why welfare improvements are the most sustainable solution.

Key Facts

Pigs account for the largest share of veterinary antibiotic use in most major pig-producing countries
Colistin use in livestock was linked to emergence of plasmid-mediated resistance that transferred to human pathogens
The EU banned antibiotic growth promoters in 2006 and preventive group treatment of healthy animals in 2022
Denmark reduced pig antibiotic use by 50% between 2010-2015 through voluntary industry-government programme while maintaining production
Pigs in high-welfare systems with lower stocking density and adequate enrichment require significantly fewer antibiotics
Reducing antibiotic use without improving welfare conditions leads to increased mortality rather than reduced disease burden

Welfare Considerations

Antibiotic stewardship and pig welfare are not separate challenges but two descriptions of the same underlying problem: pigs in poor welfare conditions become sick more often and require more medication to survive. The historic use of antibiotics as a management substitute for good welfare created a cycle that generated resistant bacteria while masking the welfare failures driving disease. Sustainable reduction of antibiotic use requires investment in the welfare conditions that reduce disease incidence - appropriate space, enrichment, good nutrition and low stress - rather than simply withdrawing medication from animals that remain in conditions that make them sick.

What You Can Do

Work with your vet to establish a written antibiotic usage plan with clear treatment thresholds and first-choice antibiotic protocols
Monitor and report antibiotic use using a validated tracking system and compare against national benchmark data
Implement welfare improvements - enrichment, stocking density, ventilation - as antibiotic alternatives before reducing treatment
Participate in national antibiotic stewardship programmes and share your usage data to contribute to sector-wide progress
Support supply chain buyers who offer incentives for reduced antibiotic use alongside demonstrated welfare improvements
Advocate for antibiotic use transparency in food labelling to enable consumer choice and drive market pressure for reduction
