Newcastle Disease (ND) in Chickens

Newcastle disease is a highly fatal disease of chicken, pigeons, quails and other domestic bird. Affected birds may die from ND even without observable signs and symptoms of the disease. Signs of infections include periorbital swelling, respiratory signs such as gasping (difficulty in breathing), rales may also be observed. More often, greenish diarrhea is present. Mortality can reach up to 100% Other sings include depression and drooping of the wings, torticollis or twisting of the neck.

Disease Transmission

ND is transmitted through infected or contaminated feces. Bird to bird transmission is often observed. Mechanical vectors can also carry the virus such as farm personnel/ visitors, vehicle, other animals within the farm. In addition, ND is also transmitted via the eggs and intestinal contents (intestinal organs) of sick birds. Lastly, ND can be spread through aerosol from one infected farm to the other.
