Bovine respiratory disease is the most costly disease of beef and dairy cattle - prevention through vaccination, housing management and early detection dramatically reduces welfare harm.
BRD welfare management represents one of the largest welfare improvement opportunities in cattle farming given its prevalence. The disease causes significant suffering through respiratory distress, fever and systemic illness. Prevention through vaccination and stress reduction is significantly more welfare-positive than relying on treatment after disease establishment. Early detection scoring systems enable treatment before disease severity escalates. The antibiotic resistance implications of metaphylaxis create tension between immediate welfare benefit and long-term welfare sustainability - antimicrobial stewardship approaches that focus treatment on affected individuals rather than whole groups are preferable when BRD prevalence allows.
