DM = dry matter; GE = gross energy; CP = crude protein; EE = ether extract; CF = crude fibre; and TMEn = true metabolizable energy corrected for nitrogen. Thirty samples of corn grains submitted from the Brazil (n = 9), China (n = 5), Iran (n = 7), and Ukraine (n = 9). All criteria were assayed with 4 replications for each corn sample (n = 120).
