Routine antibiotic use in livestock has welfare implications both for treated animals and for the broader problem of antimicrobial resistance. Responsible antibiotic stewardship serves both animal and human health.
Antibiotic use in cattle sits at the intersection of individual animal welfare and broader public health. For the individual animal, appropriate antibiotic treatment is a welfare benefit — it resolves bacterial infections that cause pain and suffering. The welfare harm arises from two directions: first, the use of antibiotics as a substitute for good husbandry that prevents disease in the first place; second, the contribution to resistance that means future sick animals may face untreatable infections and prolonged suffering. Reducing antibiotic use through improved housing, management, and disease prevention programs simultaneously improves animal welfare by addressing root causes of disease rather than masking them with medication. Certified responsible antibiotic use programs align these incentives.
