Evaluation of Different Levels of Barley and Replace it Instead of Corn on Performance of Broiler Chicken

In isoenergetic - isonitrogenous diets, barley at levels of 0, 25, 50, 75 and 100 % was substituted for corn and its effects on broiler chicken performance was studied. This study was carried out with 5 levels of barley (0, 25, 50, 75 and 100 %), 3 replicates and 14 birds in each replicate in a completely randomized design. In this experiment 300 day old broiler chicks (Lohman) were used for 42 days. The results showed that barley up to 25% substitution had no adverse effect on broiler performance. It is concluded that in diet supplementation with barley until 25% could done without any adverse effects on performance, although enzyme supplementation should be considered in the ration to decrease NSP in the barley.
