Livestock Antibiotic Stewardship and Welfare

Routine antibiotic use in livestock farming contributes to antimicrobial resistance while often masking underlying welfare problems. Reform benefits both animal and human health.

Key Facts

Approximately 70% of all medically important antibiotics globally are used in livestock production
Prophylactic antibiotic use — treating animals before they are sick — is common in intensive systems
Antibiotic growth promoters were used to compensate for poor welfare conditions in crowded systems
The EU banned antibiotic growth promoters in 2006; the US restricted them in 2017
Denmark cut livestock antibiotic use by 60% without productivity losses by improving management
Animals raised in higher-welfare conditions with lower density require significantly less antibiotic treatment

Welfare Considerations

Routine antibiotic use in livestock is both a symptom and a cause of poor animal welfare. Antibiotics are used prophylactically because crowded, stressful conditions make disease outbreaks likely and rapid. By masking the welfare consequences of intensive production, routine antibiotics allow producers to maintain systems that would otherwise be economically unsustainable due to disease losses. The Denmark example shows that reducing antibiotic use forces welfare improvements — better conditions, lower density, improved nutrition — that address the root causes of disease. Reform of antibiotic use thus simultaneously improves animal welfare, reduces antimicrobial resistance, and promotes more sustainable production systems.

What You Can Do

Choose animal products from producers that report low antibiotic use with veterinary oversight
Support legislation restricting prophylactic antibiotic use in livestock globally
Advocate for higher-welfare farming systems that reduce disease risk and antibiotic dependence
Reduce consumption of intensively farmed animal products to reduce demand for antibiotic-dependent systems
