Routine antibiotic use in livestock farming suppresses disease in overcrowded conditions rather than addressing the underlying welfare problems that make animals susceptible.
The relationship between antibiotics and animal welfare runs in both directions: farm animals kept in overcrowded, stressful conditions are more disease-prone and require more medication. Using antibiotics to maintain productivity in poor welfare conditions treats the symptom rather than the cause. The EU's progressive ban on prophylactic use has already encouraged welfare improvements in some member states, demonstrating that welfare improvement and antimicrobial stewardship can be pursued simultaneously.
