This experiment was carried out to investigate effects of fermented feedstuff added Saccharomyces cerevisiae(FFSC) on growth performance and carcass grade of growing Hanwoo bulls. Twenty six Hanwoo bulls averaging 230±24kg were randomly assigned within two dietary treatments which were control and FFSC. Average daily gain and feed intake were significantly higher in FFSC compared with control during growing, fattening and finishing period. Feed conversion was improved in FFSC compared with

During the whole experimental period, average daily gains were 1.06 and 0.98kg in FFSC and control, respectively, and it indicated that 19% was improved in FFSC compared with control(P<0.05). Feed intake was not significantly different between treatments during whole experimental period. In addition, feed conversion was not significantly different between treatments, there was a tendency to be beneficially increased about 7% in FFSC compared with control. There was no differences on yield traits including carcass weight, dressing, back fat thickness, rib-eye area and meat production between treatments. Marbling score was improved in FFSC compared with control(P<0.05). Appearances of 'A' ranked meat quantity were 44.4 and 25.0% in FFSC and control, respectively. Only FFSC had '1' ranked appearance, but there was no '1' ranked appearance in the control. (
