Extended Abstract
Introduction and Objective: There are different methods to formulate poultry diets, which is one of the newest methods, based on digestible amino acids. Meals are used to provide protein and amino acids in diets. The use of soybean meal has many limitations compared to canola meal. The use of multi-enzyme was done to reduce the limitation in flour such as canola. This experiment was conducted to evaluate the effects of diets formulated based on total and digestible amino acids, soybean and canola meals with or without adding multienzyme on the performance and carcass traits of broilers. 
Material and Methods: Experiment was conducted as 2×2×2 factorial arrangement with 800 day old of Ross-308 broilers with 8 treatments, 4 replicates and 25 chicks in each,  in a complected randomized design in 3 experimental periods (starter 1-10 days, grower 11-25 days and finisher 25-42 days). 
Results: The final results showed that diets formulated based on digestable amino acids, canola meal and enzyme by reduceing the amount of feed intake, improved chicks performance (p<0.05). Canola meal increased the abdominal fat, gizzard, liver and spleen percentages, however the percentages of breast and thighs increased this results also were abserverd in interaction between canola meal, digestible amino acids and enzyme. 
Conclusion: The overall results indicated that in broilers in the prsense of multienzyme, use of canola meal in contrast with soybean meal in diets formulated based on digestible amino acids can improve their performance and carcass traits.
