Abstract :The purpose of this study was to determine the effects of dietary addition of multi-enzymes in different source of grains based diets on performance and egg quality characteristics of laying hens. A total of 225, 24 weeks of old laying hens insert ignore into journalissuearticles values(Atak-S); were divided into 3 treatments with 5 replicates and 15 hens per replicate for 10 weeks. The control group was fed basal diet insert ignore into journalissuearticles values(without any supplementation); and treatment groups were fed basal diet supplemented 0.1% Enzyme-A insert ignore into journalissuearticles values(xylanase, ß-glucanase, cellulase, α-amilase and protease); and 0.05 % Enzyme-B insert ignore into journalissuearticles values(xylanase, ß-glucanase);. Performance and egg quality parameters were checked weekly throughout the experiment. Dietary multi-enzymes supplementation significantly changed the shape index, yolk index and yolk color insert ignore into journalissuearticles values(L and a); at different weeks of trial insert ignore into journalissuearticles values(P<0.05);. However, daily feed intake, egg production, average egg weight and feed conversion rate were not significantly affected by addition of both multi-enzymes during the experimental period insert ignore into journalissuearticles values(P>0.05);. In addition, dietary addition two types of multi-enzymes did not affect the egg specific gravity, eggshell thickness, eggshell rate, albumen index, haugh units insert ignore into journalissuearticles values(P>0.05);. As a result, it was determined that the addition of multi-enzyme additions to the laying hens of the hens between 24-33 weeks of age did not affect the performance parameters,  but caused limited changes on some egg quality characteristics .
