Study objective was to evaluate effects of dietary different levels of zinc-amino acid complex (ZAA) on growth performance, physiological parameters and gut histomorphology on broiler (ROSS308). A total 180 birds were randomly assigned to three treatments (60 birds per treatment) and three replicates per treatment with 20 birds in each replicate). Diets were prepared using a basal diet, 120 and 140 mg/kg Zn amino acid complex. Treatments showed significance in growth performance with reduced feed intake in all zinc-amino acid complex supplemented treatments in comparison to the control. Glucose, triglycerides, ALT and AST showed non-significant effects among different treatments, otherwise, cholesterol was significant in treatments 120 and 140 mg/kg compared to the basal control. In conclusion, the results showed the zinc-amino acid complex supplementation in the basal diet significantly improved and enhanced for increased growth performance and gut histomorphology. It also showed impact on cholesterol serum level.
