Calf pneumonia is the most costly disease in young cattle, causing significant suffering and mortality, with early detection and treatment protocols dramatically improving outcomes.
Calf pneumonia causes significant suffering: fever causes pain and malaise, laboured breathing is distressing, and the bacterial toxaemia associated with severe cases causes prostration. Calves are prey animals that mask illness — by the time signs are obvious, disease may already be advanced. This makes proactive, regular health scoring essential: twice-daily monitoring of respiratory rate, nasal discharge, cough, and ear position enables earlier intervention. Adequate analgesia (NSAIDs alongside antibiotics) is an important welfare measure that is often omitted — treating the infection without addressing the pain and fever leaves the calf suffering unnecessarily. Prevention through vaccination, colostrum management, and good housing ventilation is far preferable to treating established disease.
