Cattle Calf Respiratory Disease Early Detection

Early detection of bovine respiratory disease (BRD) in calves enables prompt treatment that reduces suffering, duration of illness and long-term lung damage.

Key Facts

BRD is the leading cause of morbidity and mortality in beef and dairy calves
Clinical signs including elevated respiratory rate, nasal discharge and depression are often subtle early
Validated scoring systems including the DART and Wisconsin scoring systems enable consistent detection
Early treatment within 24 hours of first signs achieves significantly better outcomes
Lung auscultation at processing allows detection of subclinical respiratory disease

Welfare Considerations

BRD causes significant suffering in calves - fever, difficulty breathing, depression and pain. Early detection through systematic scoring and monitoring allows treatment when the disease is mild, before progression to severe pneumonia with permanent lung damage. Investment in detection skills and monitoring technology pays welfare dividends through reduced suffering and better recovery.
