Pig Welfare and Antibiotic Stewardship: Progress and Remaining Challenges

Reducing antibiotic use in pig production is both a public health imperative and a welfare challenge, requiring management improvements that reduce disease pressure without compromising animal health.

Key Facts

The UK pig industry reduced antibiotic use by over 70% between 2015 and 2023 through the RUMA (Responsible Use of Medicines in Agriculture) targets
The Netherlands achieved dramatic reductions in pig antibiotic use through mandatory reporting, prescribing limits, and benchmark systems
Antibiotic stewardship requires management improvements that reduce disease pressure - including better biosecurity, housing design, vaccination, and nutrition
Critically important antibiotics such as colistin have been phased out in many pig producing countries but remain in use in some lower-income markets
Without adequate management to control disease, antibiotic reduction can result in increased disease burden and reduced welfare
Prophylactic group medication - treating whole groups regardless of disease status - is being phased out in favour of targeted therapeutic use
Metaphylactic treatment - treating all animals in a group when some are sick - remains controversial but is sometimes welfare-justified to prevent spread

Welfare Considerations

Antibiotic stewardship in pig production represents a genuine tension between public health imperatives and animal welfare. Reducing antibiotic use is essential to preserve their effectiveness for human medicine, but poorly managed reduction can result in inadequately treated animal disease. The resolution is to invest in the management improvements that reduce the need for antibiotics in the first place - better housing, biosecurity, vaccination, nutrition, and health monitoring. Where disease occurs, targeted, welfare-appropriate use of antibiotics under veterinary oversight remains ethically justified. The most advanced pig producing countries have demonstrated that it is possible to achieve major antibiotic reductions while maintaining high welfare standards through system-level management investment.

What You Can Do

Support RUMA and similar antibiotic stewardship initiatives in livestock production
Advocate for reporting and benchmarking systems that make antibiotic use transparent at farm level
Encourage investment in vaccines and management improvements that reduce antibiotic dependency
Engage with global standards bodies on extending antibiotic stewardship requirements to international pig supply chains
