Abstract

 About 50 to 80 percent of POULTRY DIETS, is consisted of energetic food stuffs like wheat, barley and corn. Since HULLESS BARLEY is consisted of high rate of energy and protein, it can be replaced instead of corn to supply some part of the required POULTRY DIETS. In order to succeed in doing this replacement, HULLESS BARLEY feeding value and estimating of METABOLISABLE ENERGY level are needed. By using the biological Sibbald method (1976), the METABOLISABLE ENERGY of HULLESS BARLEY and corn was estimated. For this experiment, adult roosters from meat breed (Arian) were used. They were divided in 11 groups and each group contained 6 roosters. Each group was forced to feed, 30 gr HULLESS BARLEY or 30 gr corn. One group was kept in fasting state. This experiment was done in 25 0C and in a completely randomized unpaired design. The results of this experiment indicated that AME, TME, TMEn of HULLESS BARLEY and corn were 3.68, 4.21, 3.32 and 3.74, 4.31, 3.56 Kcal/g respectively. There was no significant difference between the METABOLISABLE ENERGY content of HULLESS BARLEY and corn (P<0.01). Therefore, HULLESS BARLEY can be recommended in POULTRY DIETS instead of corn, because of its feeding value and cost.
