Bovine Respiratory Disease (BRD) is a common illness in cattle, primarily affecting the lungs and respiratory system. It is often caused by a combination of viral and bacterial infections, which can lead to pneumonia. Factors such as stress, poor nutrition, and environmental conditions can increase the risk of BRD in cattle. Symptoms of BRD include coughing, nasal discharge, fever, and difficulty breathing. Early detection and treatment are crucial for recovery, often involving antibiotics and anti-inflammatory medications. Preventive measures, such as proper vaccination and management practices, can help reduce the incidence of BRD in cattle herds.
