The research was conducted to investigate the effect of inovo injection with different concentrations of carnitine on some hatching , hematological traits and maternal immunity posthatching. Atotal of 500 fertile eggs were used in the experiment , those egg were randomly distributed into 5 treatments , T1:negative control , T2: injected with 0.5 ml/egg with normal saline (posative control) ,T3:injected with carnitine 1%, T4:injected with carnitine 2% and T5:injected with carnitine 3% . Results revealed a significant effect (p< 0.05) of L-carnitine injection on hatchability ,reduction of embryonic mortalities ,significant improvement of heterophil/lymphocyte ratio , significant reduction of plasma glucose of post hatched chicks and highly significant elevation of antibody titer against infections bursal disease of chickens.
