Abstract: 

An experiment was conducted to compare the effect of diet formulation based on digestible versus total amino acids with differrent levels of wheat and barley on broiler performance. This experiment designed in a factorial arrangement as a Completely Randomized Design (CRD) using 10 treatments in 4 replicates with 5 male broiler chicks in each replicate. Expermintal diets containing different levels of wheat (0, 15, 30%) and barley (0, 10, 20%) each one formaulated on digestible and total amino acid basis. Diets containing wheat or barley formulated on total or digestible amino acids basis showed no difference in broiler production parameters. Formulation of diets with barley based on digestible amino acids compared with total amino acids reduced breast meat significantly(p<0.05).With increasing levels of wheat and barley, feed consumption, FCR and viscera percentage were significantly increased (p<0.05).There was no interaction between inclusion rate of wheat and barley and diet formulation method. According to the results of this experiment, formulating of diets containing feedstuffs with high digestibility of amino acids on the digestible amino acid basis may not well justified.
