Introduction: Newcastle disease (ND) is a viral disease of birds caused by a negative sense single-stranded RNA virus known as the Newcastle disease virus. It is a disease of almost all species of domestic and wild birds with devastating impacts on poultry health and production. The aim of this study was to determine the prevalence of ND within species, breeds, age and vaccination history from the period of 2014-2018. Methods: A five- year retrospective study (2014-2018) of cases of poultry diseases diagnosed at the Avian Clinic of Veterinary Teaching Hospital (VTH), Ahmadu Bello University (A.B.U), Zaria, Nigeria was conducted, the prevalence of ND within species, breeds, age and vaccination history was determined. Case records file were collected, studied, and clinically diagnosed cases of ND were extracted. Results: It was observed that of the 1,768 poultry cases presented, 754 (42.6%) were confirmed as ND. Most cases were recorded in chickens 710 (40.2%). The prevalence was highest in the improved breed 670 (37.9%) while the local and unknown breeds had prevalence of 4 (0.2%) and 80 (4.5%) respectively. Birds within 8-13 weeks of age had the highest prevalence of 276 (15.4%) while the lowest prevalence of 19 (1.1%) was recorded in birds of unknown ages. Birds with history of incomplete vaccination (single vaccination) had the highest prevalence of 232 (13.1%), while those with complete vaccination history (three rounds of vaccination) had the lowest prevalence of 50 (2.8%). Significance: Poor management practices and improper knowledge of vaccination by the poultry handlers may be responsible for the prevalence pattern of ND recorded. Adequate biosecurity measures and routine vaccination are recommended to minimize the outbreak of ND.
