This study was carried out to investigate the effect of the feeding method of total mixed fermentation (TMF) and concentrate feed on the growth performance, carcass and meat characteristics of late fattening Hanwoo steers. Twenty-four Hanwoo steers were used in this study. The control group was fed with concentrate feed + rice straw from the growing to the late fattening period, while the T1 group was fed with TMF from the growing to the early fattening period and concentrate feed + rice straw for the late fattening period. The T2 group was fed with TMF from the growing to the late fattening period. The average daily gain (ADG) and feed conversion ratio (FCR) were not different between the treatment and control group. Serum cholesterol and high density lipoprotein (HDL) cholesterol concentrations were higher in the T2 groups than in the control group (p<0.05). The yield grade and quality grade were not different between the treatment and control group. The lightness of longissimus muscle was higher in the T1 group than in the control and T2 groups (p<0.05). Poly-unsaturated fatty acid (PUFA) of longissimus muscle was increased in the T2 groups than in the control group. Therefore, the method of feeding TMF and concentrate feed could have a positive effect on the lightness and fatty acid composition of longissimus muscle without affecting the growth and carcass grades of Hanwoo steers.
