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 kg/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.
