Bovine respiratory disease (BRD) is a common illness in cattle, primarily affecting young animals. It is often caused by a combination of viral and bacterial infections, which can lead to inflammation in the lungs. Factors such as stress, poor nutrition, and environmental conditions can increase the risk of BRD in herds. Symptoms of BRD include coughing, nasal discharge, and difficulty breathing. Early detection and treatment are crucial to prevent severe complications. Vaccination and good management practices, such as reducing stress and improving housing conditions, can help minimize the incidence of BRD in cattle populations.
