Abstract: Newcastle disease is a highly prevalent disease of poultry industry all over the world. It causes high economic losses to farmers. Vaccination has been ideal and successful method for prevention of the disease. Many live and inactivated vaccines are available commercially for control of disease. But, major limitation of vaccination method is susceptibility of infection between time of hatch and vaccination. Hence, in ovo vaccination method was developed as alternative method. In present study, 30 specific pathogen free (SPF) embryonated eggs were inoculated with inactivated Newcastle disease vaccine and 30 eggs were kept as control. After 21 days of vaccination, the hatched birds were challenged with virulent strain of Newcastle disease. The antibodies against Newcastle disease were measured by haemagglutination-inhibition (HI) method at various time intervals. The results reported that in ovo vaccination method was efficient to protect the birds from disease.
