  • Abstract : Dietary combinations of xylam and phytase, (500 xylam and 1000 phytase g/ ton); (750 xylam and phytase 1000 g/ ton); (500xylam and phytase 1500 g/ ton); (750 xylam and phytase1500 g/ ton) were added to control diet, using 168 chicks, four replicates, each of 7 chicks. All diets were formulated to be iso-caloric (3100 K cal/Kg) and iso-nitrogenous (crude protein 22.8%) to meet the nutrient requirements for broiler). Experimental parameters covered performance, slaughter and carcass data and economic appraised. The results showed that addition of combinations of microbial xylam and phytase enzymes, to diet containing Prosopis pods improved significantly (p≤0.05) the body weight gain, feed intake and feed conversion ratio values of broiler chicks throughout the experimental period. No significant differences were observed between Prosopis pods diets supplemented with the enzymes, with the control diet in body weight gain, feed intake and feed conversion ratio values of broiler chicks. The mortality rate was not significantly influenced by the dietary treatments. The results indicated that there were no significant differences among all treatment groups in percentages of carcass dressing , Giblets (liver, heart and gizzard ), commercial cuts (thigh, drumstick and breast ) and their percent of meat, meat chemical composition (moisture ,protein ,fat and ash ) and subjective meat quality parameters (tenderness ,juiciness ,flavor and color ) of broiler chicks. Economically appraised values were profitability ratio (1.94) of group C (500 xylam + 1000 gm / ton phytase) was the highest of the test groups.
