This study was conducted to investigate the effect of enzyme and yeast extract supplement on growth performance, carcass characteristics and blood parameters in Hanwoo steers. A total of forty-eight 23-month-old Hanwoo steers, with average initial body weight of 545.25±12.60 kg, were assigned to four treatments with three replicates in a completely randomized design. Hanwoo steers housed in four heads group per pen. The treatments comprised of four groups of control (no feed additives), treatment 1 (xylanase, cellulase, and gluco-amylase; 0.1%/concentrate), treatment 2 (β-glucan and mannan-oligosaccharide; 0.1%/concentrate), and treatment 3 (treatment 1+2; 0.1%/concentrate). During the fourth and eighth month, average daily gain and feed conversion rates improved in treatment 1, but in the control this was lower than the other treatments (p<0.05). Real-time ultrasound was used for measuring the live carcass traits (longissimus muscle area, back fat thickness, and marbling score) and the better results were in the following order: treatment 1 > treatment 3 > treatment 2 > control, and extended to carcass grade. White blood cell indices were lower in treatments 2 and 3 and the IgG indices were relatively higher than in other treatments. As a result, levels of xylanase, cellulase, and gluco-amylase were increased from the fourth month to improve growth performance, live carcass traits. During the second month, β-glucan and mannan- oligosaccharide increased IgG indices in blood parameters.
