Livestock Antibiotic Use and Animal Welfare

Antibiotic use in livestock has complex relationships with animal welfare, requiring careful management to protect both animal health and public health.

Key Facts

Approximately 70% of medically important antibiotics globally are used in livestock
Routine prophylactic antibiotic use masks underlying welfare problems like poor housing conditions
Antibiotic resistance threatens both human and veterinary medicine globally
Welfare reforms that improve housing conditions can substantially reduce antibiotic dependence
Denmark reduced antibiotic use by 60% without reducing productivity through systematic welfare improvements

Welfare Considerations

The relationship between antibiotic use and animal welfare is complex and bidirectional. Antibiotics treat genuine infections that cause animal suffering and should remain available for that purpose. However, routine prophylactic or growth-promotion use in poor husbandry systems substitutes drugs for welfare improvements — keeping sick animals alive in conditions that continue to cause suffering. Addressing root causes — overcrowding, stress, inadequate nutrition — reduces disease burden, antibiotic use, and animal suffering simultaneously.

What You Can Do

Choose meat from farms with antibiotic stewardship certifications
Support policies requiring veterinary prescription for all livestock antibiotics
Advocate for housing standards that address root causes of disease
Reduce livestock product consumption to decrease pressure on intensive systems
Support research into alternatives to prophylactic antibiotic use in livestock
