MungadiH.U. 1201331Newcastle Disease (ND) is a highly contagious viral disease of almost all species of domestic and wild birds. This disease is caused by a virus of genus Avulovirus, subfamily Paramyxovirinae of the family Paramyxoviridae. A five-year study (Jan, 2007-Dec, 2011) of case reports on ND and other poultry diseases diagnosed at the Avian Clinic of Veterinary Teaching Hospital, Usmanu Danfodiyo University, Sokoto (VTH-UDUS) was conducted. A total of 2,624 individual cases were documented with a prevalence of 80.9% (2,123 cases) diagnosed as ND. The result showed that there were incremental fluctuations in the prevalence of ND from 2007 to 2011. There were also variations in monthly and bird-type distribution of ND in Sokoto, with highest number of cases in March and October accounting for 88.4 and 94.4%, respectively. Layers had the highest prevalence (89.0%), followed by cockerels and pigeons (66.7%). Also intensive system of management had the highest disease occurrence of 84.7%. Poor management, improper vaccine handling and self medication practiced by the poultry farmers coupled with harsh weather conditions and inadequate diagnostic facilities may be responsible for the distribution pattern recorded. It is therefore imperative for poultry farmers to institute and intensify appropriate biosecurity measures on how to minimize horizontal transmission of the disease. Regular surveillance for ND virus should be routinely carried out.]]>Abdu, P.A.,20052005Abdu, P.A., E.K. Bawa, J.U. Umoh and L. Saidu,20052005pp: 6870Adamu, A.Y., A.B. Ahmed, M.B.
