A study was conducted to examine the effect of dietary supplementation of fermented feed(Bio-α^ⓡ) on growth performance, carcass characteristics and fecal ammonia gas release in finishing pigs. A total of 120 crossbred pigs (132 d old; Landrace × Yorkshire × Duroc) were randomly divided into 12 groups and assigned to four treatments. Pigs were fed a basal diet supplemented with 0, 0.5, 1.0 or 2.0% level of Bio-α^ⓡ. Average daily gain(ADG) and feed conversion rate were significantly improved(p$lt;0.05) by the dietary supplementation of 1.0% Bio-α^ⓡ compared with other treatments during overall experimental period. The carcass grade was improved by the dietary supplementation of 1.0% Bio-α^ⓡ, while the dietary supplementation of 0.5 and 2.0% Bio-α^ⓡ reduced the appearance of A grade (28.7 and 20.6%, respectively) compared with that (38.4%) of control treatment. Ammonia gas emission from feces was linearly decreased by increasing supplementation of Bio-α^ⓡ (p$lt;0.05). All the dietary supplementation levels of Bio-α^ⓡ reduced feed cost per unit gain, with the 1.0% level being at the lowest feed cost per unit gain (12.6% reduction from control). From this study. 1.0% dietary supplementation of Bio-α^ⓡ is suitable for the improvement of pig performance. carcass quality and feed efficiency, and reduction of fecal ammonia gas emission and feed cost per unit gain.
