\&\#61607;	This study was conducted to determine the effect of dietary gum arabic (GA) as a natural prebiotic and growth promoter on growth performance of broiler chicks. 192 one day old unsexed broiler chicks of commercial strain (Cobb) were randomly assigned into four dietary treatments; group A contained \mbox{0\,\%} GA and \mbox{60\,\%} sorghum (control), B contain \mbox{5\,\%} GA and \mbox{57\,\%} sorghum, C contain sorghum 30\%and maize \mbox{30\,\%} and D contained sorghum 28\%and maize \mbox{28\,\%} and \mbox{5\,\%} GA diets were isocolouric and isonitrogenic with two sources of energy sorghum and maize. Each treatment contained six replicates (\unitfrac[8]{birds}{replicate}). Weekly feed intake, weight gain and feed conversion ratio were measured. Results showed that feed intake and weight gain were influenced by dietary treatment, the best Feed conversion ratio was attained by group D. Pre"=slaughter weight was affected by dietary treatment. Higher pre"=slaughter weight and Carcasses weight observed for group D (sorghum 28\%and maize \mbox{28\,\%} and \mbox{5\,\%} GA).  Dressing percentage was not affected by dietary treatment. Commercial cuts (Breast weight, backbone weight, and thigh and wings weight) significantly increased for bird fed group D (sorghum 28\%and maize \mbox{28\,\%} and 5\%gum arabic). There was no significant ($p > 0.05$) difference among all groups on physical characteristic of meat (colour, water holding capacity, cooking loss and pH). Ether extract of meat for group B significantly ($p < 0.05$) decreased. Serum glucose, total protein, triglyceride and inorganic phosphorus had not affected by treatment. However serum cholesterol, calcium and creatinine showed significantly ($p < 0.05$) decrease for group B. Inclusion of gum arabic as preprebiotic in broiler chicks diets has a positive effects on broiler performance (feed intake. Body weight gain and feed conversion ratio)
