Bovine respiratory disease is the leading cause of morbidity and mortality in beef cattle, causing significant suffering and economic losses that make it both a welfare priority and an incentive for prevention.
Bovine respiratory disease represents the intersection of management stress and pathogen exposure in a way that is almost inherent to the standard beef finishing model. Transport, commingling of cattle from multiple sources, and feedlot entry conditions create immune suppression that allows respiratory pathogens to establish. Affected cattle experience fever, pain, and respiratory compromise for days to weeks before treatment or death. Early detection — using behavioral monitoring technology and regular clinical assessment — reduces time from illness onset to treatment, substantially improving welfare outcomes. Prevention through modified protocols at feedlot entry, including reduced commingling and metaphylaxis in high-risk groups, reduces incident cases.
