Abstract
This study was conducted to produce a statistical effect analysis on the testosterone concentration, carcass grade and ultrasonic measurement at 30-month-old of Hanwoo steers. A total of 186 Hanwoo steers were used. Testosterone concentration, MAR, u-LMA and u-MAR according to grade were statistically significant differenced (p = 0:021, p < :0001, p = 0:003, p < :0001). Correlation analysis showed that MAR, u-LMA and u-MAR had a positive correlation (r = 0:921, 0.475, 0.760), and testosterone was a negative correlation (r = 0:278) between the grade. LMA was positive correlation (r = 0:218), and MAR had a negative correlation (r = 0:322) between the testosterone concentration. Carcass grade (LMA, BFT, MAR) and ultrasonic carcass grade (u-LMA, u-BFT, u-MAR) were positive correlation (r = 0:768, r = 0:691, r = 0:854).
