Bovine Respiratory Disease — A Systemic Welfare Problem

Bovine respiratory disease (BRD) is the most common and costly health problem in beef cattle, affecting millions of animals annually with significant welfare implications.

Key Facts

BRD accounts for 75% of feedlot cattle illness and 50% of cattle deaths in US feedlots
Approximately 16-20% of feedlot cattle are treated for BRD at least once
Stress from weaning, transport, and feedlot entry is the primary trigger for BRD
Antibiotic treatment is effective but contributes to antimicrobial resistance concerns
Cattle with untreated BRD experience significant pain from respiratory inflammation

Welfare Considerations

BRD welfare impacts are substantial. Affected cattle have labored breathing, fever, reduced feed intake, and pain from pulmonary inflammation. Untreated or late-treated animals suffer for days or weeks. The systemic nature of BRD — driven by management practices including early weaning, long transport, and abrupt diet changes — means it is fundamentally preventable through better practice. Pre-conditioning programs that vaccinate and acclimate calves before feedlot entry dramatically reduce BRD incidence. The welfare and economic cases for prevention align strongly but implementation lags behind the science.

What You Can Do

Support beef brands that require pre-conditioning programs from their suppliers
Advocate for BRD incidence to be included as a metric in beef sustainability certifications
Support research into non-antibiotic BRD prevention strategies
Engage with food companies about supply chain cattle welfare standards
Choose beef with lower antibiotic use certifications to incentivize prevention-based approaches
