ABSTRACT

The experiment was conducted to investigate the effect of addition of Gum Arabic powder with or without xylem 500 to broiler chicks feed on the performance and serum chemistry. Three experimental diets were designed as A, B and C. A serves as control, B supplemented with 0.6% Gum Arabic and C supplemented with 0.6% Gum Arabic with xylem 500 enzyme. Sixty three broiler chicks, 7 days old were randomly distributed into three treatments, each treatment with 3 replicates and each replicate with 7 chicks. Average weight gain, feed consumption, feed conversion ratio, mortality rate, dressing percentage, noncarcass component (heart, gizzard, liver) and chemical analysis of blood serum parameters were used as a criteria of response. Results obtained showed a significant difference between treatment groups in performance parameters, dressing percentage, none carcass components and chemical analysis of blood serum. The supplementation of control diet with Gum Arabic significantly (P>0.05) decreased total cholesterol in the blood serum compared to control group which improved the general performance of broilers chicks. Economically Gum Arabic with xylem can be safely used in broiler diets without any side effects.
