다국어 초록 (Multilingual Abstract)

This study was conducted to determine the effect of feeding a mixture of broiler litter and bakery by-product on production, economy and meat characteristics of growing ?Hanwoo? steers. A control diet (conventional formulated feed and rice straw) and a treatment diet(90％ mixture of broiler litter 64％ and bakery by-product 36％ and 10％ rice straw on DM basis) were prepared on an isoenergetic basis and fed to 20 steers for 12 weeks. Palatability of TMR by ?Hanwoo? was fair. Compared with feeding a control diet, feeding a treatment diet resulted in increased(p＜0.05) DM intake, similar OM intake, similar daily weight gain(0.75 vs 0.64㎏／d) and feed efficiency of DM(10.1 vs 12.5) and OM(9.0 vs 10.6), considerably(45％) reduced(P＜0.05) feed cost／gain, and similar meat characteristics. These results show that a mixed ration manufactured with broiler litter and bakery by-product may be potentially used for growing ?Hanwoo? steers.
