N2 - This study was conducted to determine chemical composition and evaluated apparent metabolisable energy (AME) and true metabolisable energy (TME) values of five Iranian barley cultivars. Basal diet contained corn soybean and in each of the test diets barley was substituted for 30% of corn and soybean fractions. The study was carried out in 3 experiments. In experiment 1, metabolisable energy (ME) values were measured by both total collection and markers (chromic oxide) in excreta of 35-d-old chicks. In experiment 2, ME values of the barley cultivars were determined by ileal digesta procedure. In experiment 3, 36 48-d-old broiler chicks (used in experiment 1 and 2) were used to determine TME and the nitrogen corrected TME (TMEn) of the barley cultivars. Highly significant differences (P M3 ER -
