Abstract
Effects of feeding timothy hay roughage in the growing period on the beef quality with during 24 month(5 month from 28 month to) in twenty Hanwoo steers were investigated. Hanwoo steers were randomly assigned to 2 groups (10 heads/treatment), the control group (C) and the treatment group (T). Cooking loss and the shear force value of m. longissimus tended to be higher in the control group, and the panel test scores of juiciness and flavor were higher in the treatment group. However the tenderness was significantly higher in the treatment group (5.10 points) relative to the control group (4.30 points) (p<0.05). The proportion of fatty acids that were saturated ranged from $42.83{\sim}40.75%$. The unsaturated fatty acid, mono-unsaturated fatty acid and poly-unsaturated fatty acid contents in the two groups were not significantly different (59.25%, 55.61% and 3.40%, respectively, for T; 57.17%, 54.40% and 2.77%, respectively, for C) (p>0.05).
