Newcastle disease (ND) also known as Ranikhet disease (RD) is a highly contagious viral disease that attacks many species of domestic and wild bird. In spite of the availability and global employment of NDV vaccines, it always remains a constant threat to poultry producers worldwide. It is prevalent in Indian subcontinent and leads to economic losses. The present study is to design the detection of antibody titre against Newcastle disease in broiler poultry. Total 60 blood samples were collected from broiler on 7th, 14th and 21st day of post vaccination. Haemagglutination inhibition test was performed to quantify the serum antibody titre against NDV. This study revealed that the antibody titre of broiler on 7th, 14th and 21st day was 24 and 25; their respective percentage was 50% & 50%; 25% & 75% and 10% & 90%. All the age group of birds were showing protective titre which was ≥ 24 which indicates the lasota strains vaccine of NDV has significance potency against Newcastle disease of broilers.
