Effect of sawdust-bedded thickness in floors of hanwoo on meat quality of M-Longissimush after slaughter

초록

This study was carried out to investigate the effect of sawdust-bedded thickness in floors (SBTF) of Hanwoo on meat quality of M. longissimus after slaughter. The 7 mon-aged bulls (22 heads) were housed in single sheds (3x8 m(2)/animal) bedded with sawdust of 10, 15, and 20 cm thickness for 20 mon prior to slaughter. The M. longissimus from carcasses were then stored at 4 +/- 0.2 degrees C for 9 d. SBTF had no significant effect on carcass traits and pH, water-holding capacity, drip loss, cooking loss, Wamer-Bratzler shear force, aroma pattern with electronic nose, and sensory attributes of beef. The 20 cm group had the highest crude fat and the lowest n6/n3 (p < 0.05). At 9 d, the 10 cm group showed the highest total reducing ability and the lowest TBARS content (p < 0.05). During storage, the 10 and 20 cm groups had lower MetMb content, higher OxyMb content, and redder meat color than the 15 cm group (p < 0.05).
