Abstract
A total of 180 unsexed 1-day old IR broiler chicks were randomly distributed into 6 treatments  of  3 replicates each (10 birds each) in experiment for 5 weeks of age.  A factorial design (3×2) was used in which there were three levels of multienzymes, optizyme (0, 250, 500 mg/kg diet) and two levels of phytase enzyme (0, 1500 FTU/kg diet). No significant effects due to treatments on both European production efficiency factor (EPEF) and European broiler index (EBI). Bursa percentage was significantly higher in birds fed 250 mg/kg optizyme plus 1500 FTU/kg phytase. Immune organs, such as spleen and bursa of Fabricius were significantly increased with both multienzyme, optizyme plus phytase supplementation. It could be concluded that multienzyme optizyme supplementation at the level of 250 or 500 mg/kg plus 1500 FTU/kg phytase improved significantly (P<0.05) immune status of broiler chicks.
