Three experimental diets were formulated with a wheat-soybean meal diet as a reference diet (RD) and two additional diets with maize or barley included at 300 g kg<sup>−1</sup> into the reference diet. A total of 324 Cobb 500 broilers were used for the experiment in a 3 × 2 factorial with factors AL (10, 7, or 4 days) and enzyme (with or without) for cereal grains maize and barley. Birds on 10, 7, or 4 days AL were given experimental diets beginning at from d 11, 14, and 17 of age, respectively. Excreta were collected on d 20 and 21. The AME and AMEn of cereal grain were calculated by the difference method.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>There was no significant interaction between the factors for barley AME and AMEn.

However, when supplemented with an enzyme, the AME and AMEn of maize were similar at 4, 7, and 10 days AL.
