Newcastle Disease (NCD) is a highly contagious and economically damaging viral disease that affects chickens all over the world. It is marked by high mortality, which in unvaccinated flocks reaches 100%. This case study describes an NCD outbreak at a small-scale poultry farm in the Bela sub-city of Addis Ababa, Ethiopia. This farm began with 75 chickens with no previous flock history. When the owners visited the veterinary teaching hospital in Bishoftu, 15 chickens were died and 10 chickens were sick with a history of reduced feed intake, coughing, wing dropping, neck twisting, and incoordination. In addition, there were greenish watery diarrhea and depression. Hemorrhages in the trachea, gut, proventriculus, and cloaca were discovered during post-mortem examinations for gross pathological evaluation on two of the sick chickens. To save the lives of the remaining chickens and prevent economic losses, enrofloxacin oral suspension (1 ml per one liter of drinking water) was administered to 10 chickens with evident clinical signs for 5 days in a row. All fifty eight chickens were administered resergen oral immune stimulant suspension at a dose of 1 g/5 lit until excellent progress was warranted. Finally, the remaining 27 chickens healed completely and began producing eggs. Thus, to avoid economic harm to the farm or perhaps the country, poultry farming should be done using flocks that have a recognized history.
