One of the primary health concerns in poultry farming is infectious diseases. Vaccination is the cornerstone of poultry health management. Vaccines are designed to protect birds from various viral, bacterial, and parasitic diseases. Common vaccines include those for Newcastle disease, avian influenza, and marek’s disease. By immunizing flocks, farmers can significantly reduce mortality rates and improve production efficiency. Regular vaccination schedules are vital, as they help maintain a robust immune response within the flock.
