  • The present study investigated the effect of inclusion of chromium propionate (Cr-P) and lysophopholipid (LPL) in diet on blood parameters and meat quality of Hanwoo steer. Feeding trial was performed from late fattening period to slaughter and blood parameters (insulin, blood glucose and non-esterified fatty acid (NEFA) concentration) and meat quality were examined. Total 4 experimental groups including control (no addition), T1 (Cr-P 0.2%), T2 (LPL 0.2%) and T3 (Cr-P 0.1% + LPL 0.1%) were employed. For blood parameters, insulin concentration in T1 and T3 showed an elevating patterns from $3.13{\mu}U/mL$ to $3.35{\mu}U/mL$ (T1) and from $4.38{\mu}U/mL$ to $5.23{\mu}U/mL$ (T3). The changes of NEFA in all groups were detected as a decreasing patterns according to days of feeding. However, significant difference was not found. In growth performance, T2 showed greater daily gain and T1 showed greater carcass yield compared to others. However, there were no significance in difference. In meat quality, T1 showed greater yield and intra-muscular fat levels and lower sharing force compared to others. However, significant differences were not detected.
