The study included 300 unsexed broiler chicks (Hubbard) were used to evaluate (Roselle Flower) as a feed additives on the productive performance of broiler.

The chicks were divided into five groups with three replicates (20 birds in each) and fed on five diets.

Diet 1 (control group) dried Roselle flower powder were supplemented to the diet 2, 3, 4 and 5 as 0.25, 0.5, 0.75 and 1 % respectively.

Although the differences between groups for edible parts percent were not significant (Heart, Liver and Gizzard).

The hematological values PCV %, RBC, WBC and H / L ratio were increased significantly (P < 0.05) and cholesterol values decreased significantly as compared with control group.

It can conclude that Roselle as other herbal plants may be considered as a feed additive in broiler diet would improve the productive performance, hematological and biochemical values of broiler.

Diet Roselle flower supplementation of (1g / kg) might be acceptable for achieving optimum broilers performance.
