摘要

Newcastle disease (ND), one of the economically important diseases of poultry, affects all the age groups of birds and has been recorded both in vaccinated and unvaccinated flocks, which could be attributed to vaccination failure or improper handlingof vaccines. In this study, an attempt was made to study the clinical signs of ND in spontaneous and experimental cases.
