Dust exposure in feedlots causes significant respiratory irritation and disease in cattle, contributing to welfare problems that are often underappreciated. Managing dust improves cattle health and reduces antibiotic use.
Chronic respiratory irritation from dust exposure represents an underappreciated welfare burden in feedlot cattle. While less acute than clinical BRD, persistent dust exposure causes ongoing discomfort, increases mucosal inflammation, and creates conditions favoring infection. Cattle cannot remove themselves from dusty environments in feedlot settings, making management intervention essential. The welfare case for dust management is strong and aligns with economic interests since respiratory disease is the leading cause of feedlot death and treatment cost. Regular pen watering during dry periods, appropriate stocking density, and pen surface management all reduce dust loads with meaningful welfare benefits.
