Bovine respiratory disease is the most common and costly health problem in beef feedlots — causing significant welfare harm through pain, fever, and reduced quality of life.
Bovine respiratory disease represents a predictable welfare consequence of the stress-intensive feedlot entry process: cattle weaned from cows, transported hundreds of miles, mixed with cattle from multiple sources, and suddenly shifted to high-energy diets face an immune challenge at the moment their stress response has already compromised their immune function. The resulting respiratory disease causes genuine suffering — fever, pain from inflammation, and the debilitation of severe illness. The welfare-responsible approach addresses the root causes: better stress management during weaning and transport, vaccination programs before rather than after immunological challenge, and early detection and treatment once illness occurs.
