This experiment was implemented on 207 of hybrid broiler (Ross308, Cobb500) in order to know effects of hybrid and deferent levels of B-Gluganes enzyme was adding to barley (0,50,100 gm/km ration) with three replicates such every treatment. The statistical analyses appeared significant differences (P≤0.05) on live weight and average weight gains at age (4-5) weeks between two hybrid broilers. The results were in favor of Ross308 hybrid. As for B-Gluganes enzyme was cleared significant differences (P≤0.05) at age of (3-5) weeks for bwt which was in favor of the bird treatment (100gm, b- gluganes enzyme) and average of weight gains at age of (1-3), (4-5),(1-5) weeks .The third treatment was superior significant on average of weight gains than for first and second treatments. Alsobwt, we noticed significant differences (P≤0.05) on average of feed consumption and feed conversion among treatments. This results observed was decrease significant on average of feed intake and was favorite of feed conversion. As for dressing percentage was significant increase for third treatment than for other treatments. As for interaction between hybrid and adding b- gluganes enzyme were appeared significant differences (P≤0.05) on total weight gains at age of (3-5) weeks and average of weight gains at age of (1-3),(4-5),(1-5) weeks. While for feed consumption, feed conversion and netting percentage were significant differences (P≤0.05) among treatments. Conclusion for this study that Ross308 hybrid of third treatment (100gm b-glukinase enzyme) was superior significant (P≤0.05) on productive performance than other treatments.
