Abstract
The current study was conducted to investigate the effect of high quality hay on the performance and carcass characteristics of Hanwoo steers. Twenty(20) Hanwoo(7 months old) were allocated into either Control(rice straw fed) or Treatment(timothy hay and rice straw fed) group(10 animals per group) and fed for 710 days until the animals reached at 30 months old. Concentrates were fed according to the feeding program composed with three(3) phases; growing, fattening, and finishing period. For the overall feeding period, final body weights were 761.3 and 799.6kg for the Control and Treatment groups, respectively, showing 38.3kg heavier body weight in Treatment group. ADG were 0.79 and 0.84kg for Control Treatment groups, respectively. These results might be because of the intake of high quality hay during growing phase and the effects persisted until the end of the experiment. Feed intake tended to be higher in Treatment group whereas feed conversion did not show significant difference between groups. Cold carcass weights were 451.0 and 475.3kg for Control and Treatment, There were no significant difference between groups in both yield and quality grade. There were no remarkable differences in physico-chemical characteristics fatty acid composition of carcasses between groups. In conclusion, it would be beneficial to feed high quality hay such as timothy during growing period of Hanwoo steers to produce high quality beef with heavier live and carcass weight.
