Abstract: 
An experiment was conducted to evaluate the inclusion of distiller dried grain with solubles (DDGS) in commercial layer diets with Avizyme 1505. Three hundred 68 weeks-old Hy-line second cycle layers were distributed in a completely randomized experimental design in 2x4 factorial arrangement, with the variables being (DDGS) substitution for corn and soybean meal at two levels (0 or 15%) and Avizyme 1505 at four levels (0, 100, 150, and 200 gm/ton). Layer performance and egg quality were evaluated. Results showed that DDGS, Avizyme, or their interaction did not significantly affect body weight, egg production, egg weight, and egg mass. The results of this experiment suggest that DDGS level and enzyme supplementation did not significantly influence the body weight, egg production and egg characteristics parameters of second cycle laying hens.Another experiment was conducted to evaluate the effectiveness of commercial layer diets supplemented with varying levels Avizyme 1505 (0,100, 200, 500, 1000 gm/ton). One hundred and fifty 73 weeks-old Hy-line second cycle layers were distributed in a completely randomized design. Layer performance and egg quality were evaluated. The results of the present study indicated that Avizyme at the commercially recommended level or even higher levels did not significantly affect any of the performance parameters.
