Bovine and porcine respiratory disease complex cause significant suffering in cattle and pig operations. Ventilation, vaccination, and management reduce disease incidence far more effectively than treatment.
Respiratory disease in livestock causes significant suffering through breathing difficulty, fever, reduced appetite, and in severe cases pneumonia and death. It is also a major driver of antibiotic use in cattle and pig production, creating antimicrobial resistance concerns alongside the direct welfare problem. The primary preventive approach — ventilation design that removes respiratory pathogens and irritants while maintaining thermal comfort — addresses the root cause rather than managing consequences. Vaccination programs reduce disease incidence when implemented correctly. The management approach of metaphylactic antibiotic treatment at feedlot entry suppresses disease expression without addressing the underlying stress and immune suppression that makes animals vulnerable. Welfare-positive respiratory disease management invests in prevention through facility design and management rather than treatment.
