Abstract
This study included measuring of antibodies titers after vaccination with two inactivated avian influenza vaccines (H9N2).90 broiler chicks divided equally and randomly in to three groups :1st group vaccinated with Jova zeit 7 vaccine (0.3 ml / bird s.c. at one day age), 2nd group vaccinated with FLUPASOL vaccine (0.25 ml /bird S.c at the same age) and 3rd group control. The body weight of chicks in every group were calculated at (1,14,28,42) day of experiment and blood samples were collected after (1,7,14,21,28,35,42) days post-vaccination to obtain serum. indirect ELISA technique were used for the measuring of antibodies titer in the serum samples. the results showed increasing of antibodies titer (after 14 days from vaccination) in the 1st & 2nd groups but the antibodies titer in the 1st group is higher than the 2nd significantly.the result of body weight did not showed any significance between the three groups of the experiment.
