Effects of Feeding Supplementation with Macsumsuk Powders and Herb Powders as a Feeding Supplement on the Fattening Performance and Serum profile of Fattening Hanwoo steers
pp.155-171
본 시험은 맥섬석과 한약제재 첨가급여가 한우거세우의 비육능력 및 혈액성상에 미치는 영향을 구명하기 위해 생후 13개월령의 거세한우 40두(4처리×5두×2반복)를 공시하여 사료용 첨가제로 1일 사료급여량의 0.5∼1.0% 수준으로 26개월령까지 시험하였다. 시험구 배치는 C(무첨가), T1구(맥섬석 0.5% 첨가), T2구(한약제재 0.5% 첨가), T3구(맥섬석 0.5%+한약제재 0.5% 첨가)로 구분하였다. 증체량의 경우 비육전기때 T1구(226.2kg)가, 비육후기 때는 T3구(162.1kg)가 가장 높게 나타났다(p<0.05). 혈중 총콜레스테롤 함량은 T3구가 다른 처리구보다 유의적으로 높았다(p<0.05). 또한 도체중은 T3구(439.00kg) > T2(425.80kg) > T1(420.50kg) > Control(413.00kg) 순으로 낮아졌다. 배최장근 단면적은 T3구가 107.00㎠로 다른 처리구보다 높았고(p<0.05), 도체등급에서 육질등급은 T2구와 T3구가 공히 3.25로서 크게 높았다(p<0.05). 한편 등심육의 지방산 조성에서 oleic acid 함량이 48.55∼50.90%로서 가장 많은 비율을 나타내었고, 불포화지방산은 T3구(57.94%)가 다른 처리구보다 유의적으로 높게 나타났다(p<0.05). 따라서 거세한우에게 각각 맥섬석과 한방제재를 혼합하여 첨가급여하면 도체등급, 관능검사 및 불포화지방산의 개선에 도움이 될 것으로 판단된다.
This study was conducted to determine the effect of Macsumsuk powder and herb powders on the fattening performance and serum concentrations of 40fattening Hanwoo steers fed this supplement from 13 to 26months after birth. Fattening Hanwoos were randomly allotted to one of four treatment groups: C-1(control Hanwoo steers), T-1(Hanwoo steers fed a diet containing 0.5% mugwort powder), T-2(Hanwoo steers fed a diet containing 0.5% herb powder), and T-3(Hanwoo steers fed a diet containing 0.5% mugwort powder and 0.5% herb powder). The weight gain of Hanwoo steers on early fatting was higher in the T-1 group(226.2kg) than in another groups, and on finish fatting was higher in the T-3 group(162.1kg) than in another groups(p<0.05). Serum concentrations of total cholesterol were higher in the T3 groups than in the T1, T2, and control groups(p<0.05). The carcass body weight was also higher in the T3 than in the T1, T2, and control groups(p<0.05). Regarding the carcass body weigh conversion ratio, T-3(439.00kg) > T-2(425.80kg) > T-1(420.50kg) > Control(1413.00kg). Longissimus muscle area was higher in the T3 group(107.00㎠) than in the T1, T2, and control groups(p<0.05). The yield grade was higher in the T2 and T3(3.25points) than in the T1 and control groups(p<0.05). Meanwhile, percentage of oleic acid was 48.55~50.90% and UFA was higher in the T3 group(57.94%) than in the another groups in fatty acid composition of longissimus muscle(p<0.05). Consequently, Hanwoo steers are expected to improve sensory Evaluation, carcass characteristics, and unsaturated fatty acids fed up with macsumsuk powder and herb powders.
