This project was conducted to evaluation the effects of replacement of barley grain with corn grain on fattening performance of male lambs. Twenty five male lambs (6-7 month-old, average body weight = 31.22 ± 3.4 kg) were assigned randomly to five dietary treatments (5 lambs/treatment) in a randomized complete design. The first diet contained barley grain without corn grain but in the other diets from two to five corn replaced barley 25, 50, 75 and 100%, respectively. The TMR1 rations provided in pellet form. The results showed that DM and ME intake were not affected by the experimental diets (P0.05). Average feed conversion ratio was not affected by the increasing replacement of barley with corn (P0.05). The average live weight gain and average daily gain were not significant (P0.05). Feed cost ($/kg weight gain) for lambs fed diet contain 50% corn was the lower than other groups. On the basis of this study corn grain can be replaced with barley grain in lamb fattening diets without any additional cost.
