During postmortem inspection, marked congestion of trachea with hemorrhages, pinpoint hemorrhages on proventriculus, enlarged and hemorrhagic caecal tonsils, hemorrhagic lesions in the intestinal wall and inflamed cloudy and congested air sacs were observed. EDDIE App based smart phone diagnosis was not used in this case, since it has no data for poultry diseases. Cloacal and tracheal swab samples showed a positive result for NCDV. Newcastle disease is one of the most economically important poultry disease characterized by high morbidity, mortality, and spreading nature. However, rapid clinical and consistent detection of the disease with isolation of suspected hens, proper hygiene, vaccination and strict biosecurity measures can reduce the losses associated with this disease.
