Introduction Maternal immunity for Newcastle Disease (ND) can be quantified with Haemagglutination Inhibition(HI) test. Titres are expressed as log 2 values. Titres in a group are analysed statistically and mean titre in a group depicts status of flock immunity. Quantification of HI titre at day old age and subsequent quantification at weekly interval can determine the maternal antibody interfere...

l think it was better to collect blood samples at 1st , 10th , 15th & 20th days..l suggest to include ELISA Test at same time on the same samples to compare the results..l think the results will be much clear & nearly accurate.

Did you check whether this affects the sub conjunctival or intra ocular means of vaccination with B1 hitchner or B1 lasota?

Many people are now a days attributing the failure to emergence of new strains of nd which may require revision in the thinking. n.d is known to be a single strain for a long time.

The vaccintaion method at DO (group A) and at 7 days (group B) wasn't mentioned in the Materials and Method - by eye drop? or spray?. if it spray - same droplet size at DO and 7 days?
