The result of Haemagglutination inhibition test (HI) shows presence of specific Antibodies in the sera of all birds vaccinated at different levels, The Programe (one) show highest antibodies titer in the sera of birds vaccinated by drinking water (DW) at 20 days post vaccination Log2(0.86) with out significant difference than other vaccinations P<0.05. Program (two) show highest antibodies titer in the sera of birds vaccinated by D.W. at 18 day Log2 (0.76) with significant difference than other vaccinations P<0.05. Program (three) show highest antibodies titer in the sera of birds vaccinated by DW at 25 days Log2 (0.76) with out significant difference than other vaccinations P<0.05.
