Preventing Bovine Respiratory Disease through management, vaccination, and stress reduction rather than treating it after development represents the highest-welfare and most cost-effective approach to this leading feedlot mortality cause.
BRD prevention is the highest-impact welfare intervention available in beef feedlot management because it addresses the leading cause of cattle suffering in that context before it occurs rather than after. Pre-conditioning programs that vaccinate and adapt cattle to new management conditions before feedlot arrival, receiving management that minimizes commingling and processing stress, and systematic early illness detection that enables prompt treatment all reduce both BRD incidence and severity. The welfare improvements are substantial: cattle that do not develop BRD do not experience the days of respiratory distress, fever, and anorexia that characterize the disease. The economic improvements are equally substantial, making BRD prevention a model for welfare-production alignment.
