| This study was concerned with conduction of experiment for these reason three groups of broiler chicks were used. First group (which consisted of 15 chicks) was vaccinated with live attenuated vaccine (laSota strain) at age 10, 20, 30 days by drinking water. Second group (which consisted of 15 chicks) was infected experimentally with H9N2 (AMR.ANT/IRAQ/2005) 108.6 LD50/0.1ml at age 8 day then vaccinated with live attenuated vaccine (LaSota strain) at age 10, 20, 30 days by drinking water .third group (which consisted of 10 chicks) was considered as a control group without vaccination. Immune response in all chicks groups were estimated at age (40) days depending on Heamagglutination test and ELISA. The first group showed highest titer in HI and ELISA tests in comparison with second and third groups. | ||
