Routine antibiotic use in livestock farming is linked to welfare failures and contributes to the global antimicrobial resistance crisis.
Routine antibiotic use in farming is welfare-revealing rather than welfare-protecting. When animals require antibiotics to survive standard farming conditions, those conditions are the welfare problem. The antibiotic is the symptom; the overcrowding, stress, and poor ventilation are the cause. Transitioning to higher-welfare farming systems — with better space allowances, enrichment, and disease monitoring — reduces antibiotic dependency while simultaneously improving animal wellbeing.
