EFFECT OF FEEDING GUM ARABIC (ACACIA SENEGAL) WITH OR WITHOUT COMERCIAL XYLAM 500 ENZYMES ON THE PERFORMANCE OF BROILER CHICKS

Abstract

The experiment was conducted to investigate the effects of Gum Arabic powder with or without Xylam 500 to broiler chick’s diet on the performance and serum chemistry. Three experimental diets were designed as A, B, and C. A served as a control, B was supplemented with 0.6% Gum Arabic, and C was supplemented with0.6% Gum Arabic and Xylam 500 at level ½ Kg/Ton. Sixty three broiler chicks, 7 days old were randomly distributed into three treatments, each treatment with three replicates and each replicate with seven chicks. Average weight gain, feed consumption, feed conversion ratio, mortality rate, dressing percentage, non carcass component (heart, gizzard, liver) and chemical analysis of blood serum parameters were used as a criteria of response. Economics for each group was calculated at the end of the experimental period. Results showed significant between treatment groups in performance parameters, dressing percentage, non carcass components, and chemical analyses of blood serum.The supplementation of control diet with Gum Arabic significantly (P> 0.05) decreased total cholesterol, in the blood serum compares to control group and improved the general performance of broiler chicks. Chicks group fed on diet containing GA and supplemented with Xylam 500 had no significant effect on the mortality rate throughout the experimental period and consumed the lowest value of feed compared to other tested groups, also obtained the highest total profit compared to other tested groups.
