Bovine Respiratory Disease

Bovine Respiratory Disease (BRD) is a complex of respiratory infections affecting cattle. It is one of the most significant health issues in the cattle industry. BRD can lead to severe economic losses due to decreased weight gain, increased treatment costs, and higher mortality rates. The disease is caused by a combination of viral and bacterial pathogens. Common viruses include Bovine Herpesvirus, Bovine Viral Diarrhea Virus, and Parainfluenza-3 Virus. Bacteria such as Mannheimia haemolytica and Pasteurella multocida are also involved. Stress factors like transportation, weaning, and environmental changes can increase susceptibility to BRD. Symptoms include coughing, nasal discharge, fever, and rapid breathing. Early detection and treatment are crucial. Vaccination programs can help prevent BRD. Good management practices, such as reducing stress and ensuring proper nutrition, are also important. Veterinarians play a key role in diagnosing and managing BRD. They may use diagnostic tools like blood tests and lung auscultation. Treatment often involves antibiotics and anti-inflammatory drugs. In severe cases, supportive care such as fluid therapy may be needed. BRD is a complex disease that requires a comprehensive approach to management. Understanding the disease and its risk factors is essential for effective prevention and control.
