Bovine respiratory disease is the most costly and welfare-significant disease in feedlot cattle. Understanding prevention and treatment reduces suffering at significant scale.
Bovine respiratory disease causes significant suffering — fever, labored breathing, reduced appetite, and if untreated, pneumonia and death. The disease is caused by a combination of transport stress, novel pathogen exposure, and mixed-origin cattle groups. Early detection through daily observation and prompt treatment with appropriate antibiotics dramatically improves welfare outcomes and recovery rates. Prevention through vaccination programs, stress-reduction handling protocols, and adequate housing ventilation reduces disease incidence. The welfare case for early treatment aligns with economic interests — sick cattle grow poorly and medical costs accumulate.
