This study was conducted to determine the effect of dietary soybean curd residue (SCR) on the growth performance and carcass characteristics in Korean native cattle, Hanwoo steer (Bos taurus coreanae). A total of 15 cattle (8 month old and averaging 238.5±12.4 kg in weight) were divided into three dietary groups and then fed a diet containing 0 (T1, control), 25 (T2) and 35% SCR (T3) for 22 months. Meat (M. longissimus dorsi) grade were estimated by the Korean carcass grading system. In growth performance, dry matter intake (DMI) and average daily gain (ADG) were significantly higher in SCR groups (T2 and T3) than T1 group in final fattening period. Feed efficiency of T3 group was higher than other groups for all feeding periods, and carcass weight and marbling score of T3 were higher than other dietary groups. Crude fat content of meat was higher in SCR groups than T1 group. Consequently, dietary SCR could improve growth rate of cattle without any meat quality deterioration. These results may be closely related with the increase of DMI and ADG by dietary SCR.


Key words: Longissimus dorsi muscle, dry matter intake, feed conversion, marbling score.
