This experiment was carried out to investigate the effects of ruminally inserted artificial fiber (RIAF; polymerized fibrous implements) on growth performance, feed intake and carcass characteristics of Hanwoo steers. Thirty six steers averaging 368.3±20.3kg were randomly assigned into three groups: control group, the ruminal insertion of three pieces (T1), and five pieces (T2) of RIAF. Average daily gain, feed intakes and conversions among treatments were similar. Numbers of rumen villi were higher in RIAF treatment (T1 and T2) groups than control group, but they were not significant (p>0.05). The length of villi were significantly longer in T2 than control group (p<0.05). Fecal weight tended to decrease in T1 compared with the control group (p>0.05). There was no differences on carcass traits inc1uding longissmus muscle area, back fat thickness, marbling score, meat color, and fat color among treatments.
