Enzymes can eliminate the effects of antinutritional factors and to improve fish growth performance. The purpose of this study was to investigate the utilizing Kemin multi-enzyme in the diet and its effects on growth factors and some biochemical parameters in common carp (Cyprinus carpio). The experiment was conducted in completely randomized design with five treatments and three replications and multi-enzyme (Kemin®, Herentals, Belgium) at 5 levels of 0, 250, 500, 750 and 1000 mg per kg of food, was added to the diet and given the experimental diets to fishes for 8 weeks and growth factors, Weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR), Weight growth percent (WGP), Condition factor (CF) and Protein efficiency ratio (PER) were studied. Blood biochemical factors albumin, calcium, glucose and total protein were measured and evaluated. Different treatments of (CF) were not significantly different from each other (P> 0.05), But (WG), (SGR) and (FCR), the enzyme levels of 500, 750 and 1000 (mg / kg) were significantly different from control group (P <0.05). Calcium in enzyme levels of 500 (mg / kg) was significantly different from control group (P <0.05), but total protein, albumin, and glucose were not significantly different between enzyme levels (P> 0.05).
