Bovine Respiratory Disease and Feedlot Welfare

Bovine respiratory disease is the most costly disease in the beef industry and causes significant suffering in feedlot cattle, driven by the stress of transport and crowding.

Key Facts

Bovine respiratory disease BRD accounts for over 70 percent of feedlot illness and 40 percent of deaths
The stress of weaning transport and mixing with unfamiliar cattle suppresses immune function enabling infection
Metaphylaxis — mass antibiotic treatment of all new arrivals — is standard practice in many US feedlots
Cattle with BRD show reduced growth dull demeanor and labored breathing for days before death or recovery

Welfare Considerations

Bovine respiratory disease represents a welfare failure built into the feedlot production system. The sequence of weaning transport mixing and crowding that defines feedlot entry creates predictable immune suppression and disease. Animals that develop BRD experience respiratory distress fever and pain that may last days to weeks. The routine use of mass antibiotic treatment to manage endemic disease reflects an acknowledgment that the system creates welfare problems that cannot be individually managed.

What You Can Do

Choose beef from producers using lower-stress management systems with grass finishing
Support welfare standards that limit transport distances and pen sizes for feedlot cattle
Advocate for reduced stocking densities and improved ventilation as BRD prevention rather than just treatment
Reduce beef consumption from intensive feedlot systems to decrease demand driving these practices
