초록
본 연구는 마쇄보리 사료의 급여 수준이 비육 후기 한우 거세우의 사료섭취량, 일당증체량, 육량, 육질, 일반성분, 무기물 및 색도에 미치는 영향을 검토하고자 급여 기준(배합사료 기준으로 0%, 10%, 20%, 30%, 40% 마쇄보리 첨가)을 5처리 하여 실시하였다. 본 실험에서 얻어진 결과를 요약해 보면 다음과 같다. 평균 사료섭취량은 T2 > T3 > T4 > T1 > C구 순으로, 일당 증체량은 T2 > T3 > T4 > T1 > C구 순으로 높게 나타났다. 등지방 두께, 육량지수 및 등심단면적은 각각 C, T4 및 T1구에서 높게 나타났다. 특히 등지방두께는 마쇄 통보리 첨가구(T1, T2, T3 및 T4)가 C구 보다 낮게 나타났다. 근내지방도, 조직감 및 육질등급은 T1구가 가장 높았던 반면(P<0.01, 0.05) 성숙도, 지방색 및 육색은 상호 처리간 유의적인 차이가 없었다. 조지방 함량은 T1구가 17.59%로 가장 높았던 반면 T4구가 7.47%로 가장 낮게 나타났다(P<0.05). 조단백질, 조회분 및 가용무질소물 함량은 처리간 유의적인 차이를 보이지 않았다. 에너지가에 있어서는 마쇄보리 첨가구(T1, T2, T3, T4)구가 C구에 비하여 모두 높게 나타났다(P<0.01). Ca, Cu, K, Mg, Mo, Na 및 Zn 함량은 모두 C구에서 높게 나타났으며(P<0.05), Co 함량은 T2구에서 높게 나타났다(P<0.01). 명도(L*)는 C구에 비하여 마쇄보리 첨가구(T1, T2, T3, T4)에서 모두 높게 나타났지만 유의적인 차이는 없었다. 적색도(a*)는 T1구가 20.96으로 다른 구에 비하여 높게 나타났으며(P<0.05), 황색도(b*)는 C구에 비하여 마쇄보리 첨가구가 모두 낮게 나타났다. 그리고 모두 마쇄보리 첨가량이 증가할수록 떨어지는 것으로 나타났다. 이상 결과를 종합해 보면 마쇄 보리 첨가량이 10%인 T1구는 다른 구에 비하여 등심단면적, Marble score, 육질등급 및 명도가 다른 구에 비하여 높은 것으로 나타났다.
Abstract
This study was carried out to investigate the effects of the level of cracked whole barley on daily feed intake, daily body weight gain, carcass characteristics and meat composition of finishing Hanwoo steers(feeding from 24 months to 30 months of age). The dietary treatments were consisted of five types(C;normal concentrate as a basal diet, T1;10% addition of cracked whole barley, T2;20% addition of cracked whole barley, T3;30% addition of cracked whole barley, T4;40% addition of cracked whole barley). A total 30 Hanwoo steers(588.6±11.8kg) were allocated to 5 feeding groups. The daily feed intake and daily body weight gain were high in the order of T2 > T3 >T4 > T1 > C. The back fat thickness and longissmus muscle area were highest in C and T1, respectively(P<0.05) than other treatments. The meat yield index decreased with increased back fat thickness. The marbling score and meat quality were highest in T1(P<0.01, 0.05, respectively), but maturity, fat color and meat color were not significantly different among treatments. The crude fat was highest in T1(17.59%), while in T4(7.47%) it was lowest(P<0.05). The crude protein and crude ash were not significantly different among treatments. The energy value of cracked whole barley treatments(T1, T2, T3, T4) was higher than C(P<0.05). The contents of Ca, Cu, K, Mg, Mo, Na and Zn were higher in C than the other treatments(P<0.01), but Co was higher in T2(P<0.01). The CIE L* value of whole cracked barley treatments(T1, T2, T3, T4) was higher than C, however there were not differences among the treatments. The CIE a* value was highest in T1(P<0.05) than others. The CIE b* value was highest in C and it was decreased with increased feeding of cracked whole barley. Based on the above results, T1 treatment compared to other treatments improved the carcass quality parameters like loin muscle area, marbling score, meat quality, and CIE L* value.
