This study was conducted to evaluate the effects of a high protein diet containing barley on the growth performance and carcass characteristics of finishing pigs. A total of fifty six [(LandraceYorkshireDuroc)] pigs (85.08 kg in average initial body weight) were used for a 6-week study. Dietary treatments included 1) Basal diet (CON) and 2) High protein diet with barley 5% (HB5). During the entire test periods, there were no significant differences in Average daily gain (ADG), Average daily feed intake (ADFI) and gain/feed ratio between treatments (p>0.05). The b value of M. logissimus dorsi muscle color was significantly increased in CON fed pigs compared to pigs fed the HB5 diet (p<0.05). The water holding capacity (WHC) was higher in HB5 than CON fed pigs (p<0.05). Also, drip loss was significantly decreased in HB5 compared to CON fed pigs (p<0.05). Backfat thickness, live weight, cold carcass weight, dressing, and carcass grade were not significantly affected by either treatment (p>0.05). In conclusion, the results of this study indicate that a high protein diet with 5% barley affects meat color, WHC and drip loss in finishing pigs.
