Newcastle disease (ND) is a highly contagious viral disease affecting most of the avian species. The mortality of birds varies with the virulence and pathogenicity of virus that infects the birds and also with susceptibility of birds. Though ducks are resistant to ND, there are some studies reported that the susceptibility of some breeds of ducks to NDV. In this present study, two exotic breeds of ducks (White Pekin and Khaki Campbell) were experimentally infected with 105 Egg Infectious Dose50 of velogenic Newcastle Disease Virus (vNDV) by subcutaneous route on 15th day of age to study the pathogenicity of NDV in ducks. | Evaluation of histopathological changes in ducks infected with newcastle disease virus
