Bovine Respiratory Disease (BRD) is the most costly and welfare-damaging disease in beef cattle farming. Understanding prevention and management reduces suffering and improves farm economics simultaneously.
BRD causes significant suffering — fever, respiratory distress, lethargy, and potential fatal pneumonia. The stress cascade that enables BRD (weaning + transport + mixing + novel environment in rapid succession) is largely a management choice. Reducing this stress burden through low-stress handling, gradual weaning, shorter transport, and stable social grouping reduces disease incidence without antibiotic metaphylaxis. Early detection through precision monitoring systems (bolus temperature sensors, rumination collars) enables timely individual treatment that reduces severity and duration of suffering. The welfare-economics alignment is clear: animals that do not get BRD grow faster, have lower mortality, and require fewer antibiotic treatments.
