The present study investigated the effects of Lysophospholipid (LPLs, LIPIDOLTM) on the growth performance and nutrient digestibility of Hanwoo heifers. A feeding trial was performed for 120 days until slaughter using a herd of 24 Hanwoo heifers. Eight heifers were assigned to each of 3 experimental groups (control, 0.3% LIPIDOLTM and 0.5% LIPIDOLTM). Growth performance, nutrient digestibility, and carcass characteristics were investigated. Significantly improved nutrient digestibility was found in the LIPIDOLTM treatment group compared to the control (p0.05). No significant effect by LIPIDOLTM supplementation on growth performance was observed (p0.05). However, interestingly, greater carcass weight was detected in the treatment of LIPIDOLTM where less daily gain was found. Although not a significant effect, greatly decreased back-fat thickness and increased loin area were detected in the treatment of LIPIDOLTM. In meat characteristics, LIPIDOLTM increased intramuscular fat and tenderness. Therefore, the present study results suggest that the inclusion of LIPIDOLTM in the diet of Hanwoo heifers can improve carcass performance and meat quality by increasing the carcass index and the meat quality index. The results also suggest that a level of 0.3% might be more efficient than 0.5% with regard to economic effectiveness.
