This study was conducted to evaluate the effects of palm pollen and Gingko Biloba as feed additives, on productive performance, biochemical parameters and immune response of broiler chickens. A total of 210 one day-old chicks of Ross 308 hybrid were divided into 3groups, (each n=70). First group (Control group), the chicks were fed on basal diet(C), second group (P), were fed on the same diet enriched with 0.5 % palm pollen, third group (G), were fed on the same diet enriched with 0.5 % Gingko Biloba (GB). During 45 days of the experimental period, the broiler performance including feed intake and body weight gain, final body weight, feed conversion ratio (FCR), carcass weight, thigh and breast weight , liver weight, biochemical parameters and antibodies titer for Newcastle and Infectious Bursal diseases vaccines were measured. Significant  differences were observed between different treatments and control, at the end of the experiment (45 days), the highest body weight gain was recorded by (P) Palm Pollen enriched group (2345.45±190 g) followed by (C) control group (2170±277g) then came (G) Ginkgo Biloba (1927.27±98.4g). The impact on FCR followed the same order of live body weight. Better biochemical and immune responses were recorded in both treated groups than control one. The carcass yields were found that, thigh weight higher in P followed by C then G, while breast were higher in treated groups.

From the results of this experiment, it can be concluded that addition of palm pollen to broiler diets significantly improved the body weight gain and feed conversion indices all over the period of raising while, Ginkgo Bioloba improved immune response and biochemical parameters of broilers. Finally, we could recommended the use of palm pollen as growth promoters and immune enhancer and Ginkgo Biloba as immune enhancer only, at feeding practices.
