Abstract

Seventy-two Korean native bulls, with an average initial body weight of $247.2{\pm}2.34kg$ were used to determine the effect of different flaked lupin seed inclusion levels (0%, 15% and 30%; Control, LS15, LS30, respectively) on growth with a $3{\times}3$ randomized complete block design at the experimental farm of TS Corporation in Korea for 150 days. There were no significant differences in average daily gain (ADG) and feed:gain among treatments, However, LS30 increased concentrate intake and total feed intake (p<0.05) and decreased rice straw intake compared with Control and LS 15 (p<0.05), With inclusion of flaked lupin seeds, concentrate intake and total feed intake increased (p<0.01) and rice straw intake decreased (p<0.05) compared with Control. There were no specific changes in the health status of animals used in this experiment with inclusion of flaked lupin seeds in concentrates. Inclusion of flaked lupin seeds in the concentrates showed a tendency of reduced average daily total feed cost per kg weight gain compared with Control by 1.6% and 3.4%, respectively, in LS15 and LS30.
