Forty-two Hanwoo steers (average age of 5.1 ± 0.8 mo.
with body weight of 147.05 ± 10.85 kg) were randomly allotted into FC (animals fed flakes for entire experimental period)
and GC (animals fed grounded concentrate during growing and fattening phases followed by flaked concentrate during
finishing phase) groups for 758 d after reaching an age of 30.0 ± 0.82 mo. There was no difference in body weight (BW)
or ADG between the treatments until fattening (15 ~ 22 mo.) phase. However, by finishing phase (23 ~ 30 mo.), the GC
group (739.24 kg BW and 0.67 kg ADG) showed greater (P < 0.05) BW and ADG than the FC group (702.93 kg BW and
0.59 kg ADG).
