Bovine Respiratory Disease Prevention

Bovine respiratory disease (BRD) is the most costly health problem in beef cattle, causing significant suffering and preventable deaths in feedlot and stocker operations.

Key Facts

BRD accounts for over 70% of feedlot cattle illness and 40-50% of all feedlot deaths
Risk peaks in the first 45 days after feedlot arrival during the stress of mixing and transport
Vaccine protocols reduce BRD incidence but timing and product selection are critical
Metaphylaxis — treating all high-risk cattle on arrival — reduces BRD but raises antibiotic use concerns
Early detection through behavioral monitoring improves treatment outcomes and reduces suffering duration

Welfare Considerations

BRD causes acute respiratory distress, fever, and pain in affected cattle, with progression to chronic lung damage and death in severe cases. The welfare burden is compounded by delays in detection — cattle are stoic prey animals that often do not show obvious illness until disease is advanced. Stress from transport, mixing, and novel environments at feedlot entry creates the immunosuppressive window when BRD most commonly strikes. Welfare-conscious management combines stress-reduction protocols at arrival, timely vaccination, and active surveillance to identify and treat sick animals early.

What You Can Do

Support cattle welfare standards that include BRD prevention and surveillance protocols
Choose beef from producers with verified health management programs
Advocate for stress-reduction practices at feedlot entry — adequate rest, water, feed
Support research into BRD vaccines and non-antibiotic prevention strategies
Engage with livestock health as an animal welfare issue, not just a production concern
