Problem statement: Endogenous enzymes of broilers cannot adequately digest nonstarch&#13; polysaccharides and subsequently the ingestion of high levels of soluble NSP leads to increased digesta&#13; viscosity and reduced nutrient digestibility and absorption. Supplementation of NSPs degrading&#13; enzymes may remove the anti nutritive effects of NSPs and release some nutrients (starch, protein)&#13; from these elements. Therefore, in a completely randomized design the effects of a multi-enzyme&#13; (Endofeed W produced from Aspergillus niger, with minimum activity of 2250 u g&#8722;1 xylanase and&#13; 700 u g&#8722;1 &#946;-glucanase) supplementation on performance, carcass characteristics, carcass composition&#13; and some blood parameters in Cobb 500 broilers fed on corn-soybean meal-wheat diets were studied.&#13; Approach: A total of 150 one-day-old broiler chicks (Cobb 500) were used in a completely&#13; randomized design with 2 treatments and 3 replicates. The main ingeridients of diets included corn,&#13; soybean meal and wheat. The enzyme levels added to the diets were 0.00 (control) and 500 mg kg&#8722;1&#13; DM. Results: Enzyme supplementation significantly improved relative growth, energy efficiency and&#13; protein efficiency from 11-28 days of age. Adding enzyme significantly decreased body weight gain,&#13; feed intake and improved feed to gain ratio, energy efficiency and protein efficiency from 29-44 days&#13; of age (p<0.05). Relative growth, energy efficiency and protein efficiency was increased and body&#13; weight gain, feed intake and feed to gain ratio was decreased by enzyme supplementation from 1-44&#13; days (p<0.05). Enzyme addition significantly increased carcass and thighs + drumsticks percentages at&#13; 44 days of age. Adding enzyme significantly increased the concentration of blood Triiodothyronine&#13; (T3) at 28 and 44 days and reduced the concentration of blood Thyroxine (T4) at 44 days of age.&#13; Enzyme inclusion increased the concentration of blood total cholesterol at 10, 28 and 44 days of age,&#13; however triglyceride concentrations increased at 10 and 44 days (p<0.05). The concentration of blood&#13; uric acid was significantly decreased at 28 and 44 days in broilers fed enzyme supplemented diets.&#13; Conclusion: Results of this study indicated that supplementation diets with 500 mg kg&#8722;1 multi-enzyme&#13; (Endofeed W) in corn-soybean meal-wheat based diet improved broiler chickens feed to gain ratio,&#13; carcass yield and it can change the concentrations of thyroid hormones and some metabolites in blood,&#13; but it had not significant effect on carcass composition
