Bovine Respiratory Disease is the most economically significant and welfare-damaging condition in cattle, with prevention and prompt treatment being critical welfare interventions.
BRD welfare represents the intersection of animal suffering at scale with complex management decisions. Cattle with respiratory disease experience fever, labored breathing, and systemic illness that causes significant suffering. The welfare imperative for early detection and treatment is clear - delayed treatment produces worse outcomes and prolonged suffering. The prevention side is more complex: vaccination programs reduce disease but do not eliminate it, while metaphylactic antibiotic use raises resistance concerns balanced against welfare benefits of disease prevention. Improved diagnostic tools enabling early, targeted treatment rather than metaphylaxis represent a welfare and antimicrobial stewardship improvement.
