옻나무 분말, 규산염 및 크롬메티오닌을 급여한 한우육의 냉장저장 중 육질 비교

This study was carried out to compare the meat quality of beef from Hanwoo supplemented with dietary Rhus verniciflua Stokes (RVS) meal, silicate (Si), and chromium-methionine (Cr-Met) during refrigerated storage. The 26 mon-aged Hanwoo steers were fed basal diets containing 4% RVS, 4% RVS+400 ppm Cr-Met, 1.4% SiO2, or 0.14% SiO2+400 ppm Cr-Met for 4 mon prior to slaughter. The M. longissimus from carcasses were then stored at 4±0.2℃ for 7 d. The crude fat content was higher in the Si and Si+Cr-Met groups (p
