Cattle BRD Metaphylaxis and Welfare Considerations

Metaphylactic antibiotic treatment of high-risk cattle groups raises welfare and antimicrobial resistance concerns requiring careful evaluation.

Key Facts

BRD affects up to 40% of beef cattle in feedlots and causes significant mortality
Metaphylaxis treats whole groups when risk of BRD is high, even if not all are sick
Mass treatment can reduce suffering in genuinely sick animals within a group
Concerns include treating healthy animals and contributing to AMR
Improved sourcing, housing, and vaccination can reduce metaphylaxis dependence

Welfare Considerations

When a high proportion of animals in a group will develop BRD, metaphylaxis may prevent significant suffering. However, it should not substitute for addressing root causes of disease risk. A welfare-focused approach uses metaphylaxis judiciously while investing in prevention through better management and biosecurity.

What You Can Do

Support beef welfare standards measuring antibiotic use alongside health outcomes
Choose beef from farms with documented disease prevention programmes
Advocate for vet prescribing data on metaphylaxis to inform AMR and welfare policy
