Abstract: In the present experiment, serological haemaglutination inhibition (HI) test has been done using serum samples obtained from three breeds of chickens viz. COB-100, BV-300 and Hisex 9. For comparative evaluation of maternally derived antibody (MDA) against Newcastle disease (ND), 10 samples of COB-100 & BV-300 and 5 samples of Hisex 9 were used. All the chickens were the progeny from the parentstock that had the history of vaccination. For sero monitoring of NDV disease specific antibody in mature chickens, 10 samples, each of Hisex 9 chickens of age 34 and 48 weeks, were used for the study. The average MDA against ND were found different in the three different breeds, ranging from 98.50 in COB-100, 74.64 in BV-300 and 69.65 in Hisex 9. The level of antibody were found significantly different in two different age groups of the same breed Hisex 9 and were 98.50 in 34 weeks old chicken and 26.30 in 48 weeks old chicken respectively. The level of MDA against ND was not found significantly different in the parent stock having the history of vaccination. On the other hand, the level of antibody in mature chicken was found significantly different. The studies suggest a vaccination schedule within 10 days for a day old chicken and also close monitoring the antibody level before and after vaccination in mature chicken.
