Bovine Respiratory Disease and Calf Welfare

Bovine Respiratory Disease is the most costly disease in beef and dairy calves, causing significant welfare compromise and economic losses.

Key Facts

BRD causes approximately 25-30% of pre-weaning calf mortality in beef systems
Stress from transport, weaning and commingling dramatically increases BRD susceptibility
Early detection using clinical scoring systems allows prompt treatment improving outcomes
Metaphylactic antibiotic treatment of entire groups is used prophylactically at high-risk events
Vaccination programmes combined with stress reduction provide the best BRD prevention

Welfare Considerations

Bovine Respiratory Disease causes significant suffering through acute pneumonia with fever, laboured breathing and reduced activity. Calves with BRD experience weeks of illness before either recovery or death, with chronic cases developing lasting lung damage affecting lifetime welfare and performance. The welfare burden of BRD is compounded by the management events that trigger it: transport, weaning and commingling occur simultaneously in many beef systems, overwhelming calf immune systems at their most vulnerable. Separating stressors, improving housing ventilation and implementing vaccination reduces BRD prevalence substantially.

What You Can Do

Support beef and dairy certification schemes with BRD prevention protocols
Advocate for stress reduction in calf management reducing the multiple simultaneous insults that trigger BRD
Choose beef from farms with low calf mortality and antibiotic use through documented welfare management
Support research into BRD prevention strategies reducing antibiotic dependence
