The routine use of antibiotics in intensive animal farming contributes to antibiotic resistance, while masking underlying welfare problems that better farming practices should address.
Antibiotics in farming are often used prophylactically because production systems create conditions where disease is inevitable without them. This masks poor welfare rather than addressing it. Animals in high-welfare environments with lower stocking densities, better nutrition, and reduced stress have lower disease rates and require fewer antibiotics. Antibiotic resistance threatens both animal welfare (untreatable infections) and human health, making this a critical One Health issue.
