Livestock Antibiotic Stewardship and Animal Welfare

The use and misuse of antibiotics in livestock farming has direct welfare implications for the animals treated, as well as contributing to the global crisis of antibiotic resistance.

Key Facts

Approximately 73% of global antibiotic use occurs in food animal production, predominantly in pigs and poultry
Antibiotics were historically used as growth promoters — a practice now banned in the EU and restricted in the US
Prophylactic antibiotic use — treating healthy animals to prevent disease — remains common in high-density livestock systems
Antibiotic resistance in human pathogens is directly linked to livestock antibiotic use through horizontal gene transfer
Animals denied appropriate antibiotic treatment for bacterial infections suffer unnecessarily from treatable disease
The WHO Critical Importance list designates certain antibiotics as last-resort human treatments; their livestock use raises alarm
Countries that have restricted antibiotic use in livestock — Denmark, Netherlands — have maintained productivity while reducing resistance
Welfare-centered antibiotic stewardship uses antibiotics only for diagnosed disease in individual animals with appropriate withdrawal periods

Welfare Considerations

Antibiotic stewardship in livestock creates a genuine welfare tension: reducing antibiotic use preserves the drugs as effective treatments (a long-term welfare benefit), but inappropriately restrictive policies can deny sick animals effective treatment (an immediate welfare harm). The welfare-aligned position is not simply antibiotic reduction, but antibiotic optimization — using antibiotics when individual animals are sick and bacterial infection is the cause, while eliminating routine prophylactic and growth-promotion use. This requires investment in the housing, husbandry, and biosecurity conditions that reduce disease incidence to levels where individual treatment rather than herd-level prophylaxis is feasible. The link between high-density housing, disease risk, and antibiotic dependence means that genuine antibiotic stewardship requires addressing the underlying welfare conditions that make drug dependence necessary.

What You Can Do

Choose meat products from producers who have committed to antibiotic stewardship programs with transparent reporting
Support regulatory limits on prophylactic and routine antibiotic use in livestock farming in your country
Advocate for antibiotic use data reporting requirements for large livestock operations
Reduce overall meat consumption to lower demand pressure on intensive systems with highest antibiotic dependence
