Cattle Respiratory Disease: Welfare Implications of a Major Cattle Illness

Bovine respiratory disease (BRD) is the most common and economically significant disease of beef and dairy cattle, causing significant pain and suffering in millions of animals annually.

Key Facts

BRD affects approximately 20% of beef calves and causes up to 75% of calf deaths in feedlot settings
The disease involves a complex of viral and bacterial pathogens exacerbated by stress and poor conditions
Transport stress, mixing of animals, and overcrowding are major risk factors for BRD outbreaks
Early detection through clinical scoring systems significantly improves treatment outcomes
Pain and fever associated with BRD cause welfare suffering that is often inadequately treated

Welfare Considerations

Cattle with BRD experience fever, chest pain, difficulty breathing, and profound depression. The disease course can last days to weeks, during which animals are clearly suffering. Inadequate or delayed treatment prolongs suffering unnecessarily. Pain relief (NSAIDs) alongside antibiotics significantly improves welfare outcomes but is not universally used. Prevention through management - reducing transport stress, gradual mixing of cattle, vaccination, and good nutrition - is both welfare-positive and economically beneficial.

What You Can Do

Support farming standards that require prompt treatment and pain relief for BRD-affected cattle
Advocate for mandatory use of NSAIDs alongside antibiotics in BRD treatment protocols
Support research into BRD prevention through management and vaccination improvements
Choose beef products from farming systems with documented BRD monitoring and treatment protocols
Engage with agricultural vets to promote welfare-positive BRD treatment standards
