Newcastle Disease in Poultry

Newcastle Disease is a highly contagious viral disease that affects chickens of all ages and causes heavy mortality in poultry farms. The disease spreads through air, infected birds, contaminated equipment and human movement. Common symptoms include respiratory distress, greenish diarrhea, drop in feed intake, twisted neck, paralysis and sudden death. There is no effective treatment once the disease appears, making vaccination and strict biosecurity the only reliable control methods. This disease causes severe economic losses if preventive measures are ignored.
