One thousand two hundred Ac laying hens (22-33th week of age) were used to evaluate the effect of energy levels on production, egg quality and economic returns. The experiment was allocated according to a completely randomized design into four treatments: control (using concentrate for Ac hens of CP Vina Company) and 3 different energy levels of 2789 kca1/kg (MEh), 2647 kca1/kg (MEm) and 2573 kca1/kg (MEi) with ten replicates. Experimental diets were isonitrogenous formulated at 16 percent. Dietary treatment had significantly affected on egg production, feed intake feed and efficiency (P=0.01), the highest values were found on the MEh and the control, while egg weight and egg mass were similar among diets (P=0.66). Energy levels did not affected on Haugh unit, shape index and albumin index or shell ratio, but increasing energy to the diet increased egg shell thickness (p=0.01). The lowest feed cost was found in the high energy level diet.
