Livestock Antibiotic Use and Animal Welfare Implications

Routine antibiotic use in livestock farming reflects underlying welfare problems while also creating antimicrobial resistance risks that threaten human and animal health globally.

Key Facts

80% of antibiotic use in the US occurs in livestock and poultry
Antibiotics are used prophylactically to prevent disease in crowded conditions
AMR threatens to make 10 million deaths annually untreatable by 2050
Denmark reduced livestock antibiotic use by 50% without productivity loss after reforms

Welfare Considerations

High antibiotic use signals underlying welfare failures: animals in unhealthy, overcrowded conditions need medication to survive. Eliminating prophylactic antibiotic use requires improving conditions so animals are healthy without drugs. This is both a welfare intervention and a public health imperative. Countries that have reformed find animal welfare and productivity improve together.
