A grower broiler experiment (from 1 to 5 weeks of age) was conducted to study the impact of various commercial feed additives on performance and economical efficiency of broiler chicks. These additives included commercial premixture of flavouring substance (Biostrong® 510), commercial enzyme preparation (Nutrikem dry® and symbiotic (Bio-gen®). A number of 120 Hubbard broiler chicks (1 week of age) were divided into 4 treatment groups (3 replicates of 10 chicks, each). Groups were assigned to 4 experimental diets: a basal diet of no additive (control), the basal diet supplemented with either 150 g/ ton Biostrong (T1), 500g/ton Nutrikem dry (T2) or 500 g/ton Bio-gen (T3). The results indicated that: 1- Supplementation of Biostrong or Nutrikem recorded insignificant higher body weight gain by (8 and 3%, respectively) than the control or Bio-gen groups. 2- Supplementation of Bio-gen recorded significant (P<0.05) higher feed intake and worst feed conversion (1.81) than those fed other dietary treatments, but numerically Biostrong and Nutrikem treatments (T1 and T2) represented the best feed conversion (being the same figure 1.54 g) compared with that fed control diet (1.65). 3- Carcass characteristics parameters (dressing, giblets and abdominal fat %) and carcass parts % (breast, thigh, drumstick and wing %) showed insignificant figures when chicks fed different dietary treatments. 4- Bone measurements (wet tibia weight and tibia width) showed insignificant figures, however tibia length and tibia Seedor index have significant differences for dietary treatments. 5- Biostrong (T1) and symbiotic (T3) significantly improved the total protein, and globulin values compared with T2 group. However the T3 treatment and control have the best A/G ratio. 6- Enzyme treatment (Nutrikem, T2) decreased plasma triglycerides cholesterol and LDL concentrations compared with other treatments (T1 and T3). 7- Concerning economic evaluation, the best economical efficiency value was demonstrated when broiler chicks fed 150 g/ton Biostrong (T1) and the value was 21% more when compared with that of broiler chicks fed control diet. It could be concluded that supplementation basal diets with 150 g/ton Biostrong improved productive performance and enhanced economic efficiency of Hubbard broiler chicks.
