Abstract
ABSTRACT To investigate the effects of total mixed ration (TMR) on growth performance and carcass characteristics of Hanwoo steers, sixty steers were randomly assigned to one of four treatment groups; separate feeding of concentrate and rice straw (control), wet TMR (TMR), dry TMR with 20% (TMR) and 40% (TMR) barley bran from 6 to 28 month of age. In growth performance, average daily gains of TMRgroup was the highest (0.70 kg/day) but significant differences between treatments were not found (p>0.05). Average feed required for kg body weight gain of control group was 11.63kg. Those of TMRthrough TMRwere 9.29, 10.46 and 10.71 kg, respectively. Dressing percentage and retailed cut percentage were 59% and 63%, without any significant differences between treatments (p>0.05). There were no significant differences in rib-eye area, back fat thickness, meat color and fat color (p>0.05). Average marbling score was higher(p<0.05) in TMRthan in control group.( Key words : Total mixed ration, Hanwoo steer, Carcass characteristics, Economic efficacy)
