Second group (which consisted of 15 chicks) was infectedexperimentally with H9N2 (AMR.ANT/IRAQ/2005) 108.6 LD50/0.1mlat age 8 day then vaccinated with live attenuated vaccine (LaSota strain)at age 10, 20, 30 days by drinking water .third group (which consisted of10 chicks) was considered as a control group without vaccination.Immune response in all chicks groups were estimated at age (40) daysdepending on Heamagglutination test and ELISA.
