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).

본 연구는 거세한우에 대한 육성기의 티머시 건초 조사료의 급여효과를 구명하기 위하여 거세우 20두를 공시하여 대조구와 시험구의 2개처리구로 생후 5개월 부터 28개월까지 24개월간 비육시험한 후 등심부위 근육을 분석하였다. 가열 감량, 전단력은 대조구가, 다즙성, 향미는 시험구가 다소 높은 경향이었지만, 관능검사 결과 연도는 시험구(5.10점)가 대조구(4.30점)보다 통계적인 유의성이 인정되었다(p<0.05). 지방산 조성에서 포화지방산은 $42.83{\sim}40.75%$ 범위였고, 불포화지방산과 MUFA 및 PUFA은 시험구(59.25%, 55.61%, 3.40%)와 대조구(57.17%, 54.40%, 2.77%)간에는 통계적인 유의차는 없었다(p>0.05).
