Popis: The present study investigated the effects of Lysophospholipid (LPLs, LIPIDOL™) 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% LIPIDOL™ and 0.5% LIPIDOL™). Growth performance, nutrient digestibility, and carcass characteristics were investigated. Significantly improved nutrient digestibility was found in the LIPIDOL™ treatment group compared to the control (p 0.05). However, interestingly, greater carcass weight was detected in the treatment of LIPIDOL™ 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 LIPIDOL™. In meat characteristics, LIPIDOL™ increased intramuscular fat and tenderness. Therefore, the present study results suggest that the inclusion of LIPIDOL™ 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.
