Antibiotic-free livestock production systems have demonstrated that better welfare and reduced antibiotic use can be achieved simultaneously.
Operations that have successfully reduced antibiotic use have typically done so by improving welfare conditions that reduce disease susceptibility. Lower stocking densities, better enrichment, improved ventilation, and proactive health management reduce the disease burden that drives antibiotic use. The welfare-antibiotic nexus creates aligned incentives: improving welfare reduces disease reducing antibiotic need improving public health.
