Cattle BRD Metaphylaxis and Welfare Implications

Bovine respiratory disease metaphylaxis - treating whole groups when some show disease - raises animal welfare and antibiotic stewardship questions.

Key Facts

BRD is the leading cause of mortality and antibiotic use in feedlot cattle
Metaphylaxis treats all incoming cattle to prevent outbreak spread
Evidence supports metaphylaxis welfare benefit by preventing severe disease
Selective treatment of high-risk individuals reduces antibiotic use
Early individual treatment protocols can replace mass medication

Welfare Considerations

BRD causes significant pain and distress. Metaphylaxis, when appropriately targeted, reduces welfare harm at herd level. However, mass antibiotic use without individual assessment undermines stewardship goals. Balancing welfare benefit against antibiotic resistance risk requires good clinical judgment and monitoring.

What You Can Do

Support veterinary-led antibiotic stewardship programs on farms
Advocate for early detection and individual treatment protocols
Buy beef from farms with documented low antibiotic use
