생시체중 25kg인 흑돼지 360두에 단백질 원료인 탈피대두박(DSBM)과 일반대두박(NDSBM)를 80kg까지 각각 급여하였다. 비육기에는 고에너지(ME 3.265kcal/kg)와 저에너지(ME 2,940 kcal/kg) 사료를 출하까지 급여하여 생산성, 도체 및 육질 특성을 분석하였다.생산형질에서 T1 처리구가 일당증체량에서 다른 처리구에 비하여 높았다(P<0.05). 사료요구율은 T1이 다른 처리구에 비하여 낮았다(P<0.05). 도체 특성에서, 도체율은 T2 처리구가 T1과 T4에 비하여 높았다(P<0.05), 등지방두께에서는 T2 처리구가 T1과 T3에 비하여 낮았다(P<0.05). 도체등급은 B이상 상위 등급출현 비율은 T2 처리구에서 높게 나타나는 경향이다. 육질특성에서 각 처리구에서 일반성분 함량은 유의차가 없었다. 보수력은 T4 처리구가 높은 경향을 나타내었고, 전단가는 T1 처리구에서 높은 경향을 나타내었다. 신선육의 육색은 L* 및 a*값은 T2 처리구가 높은 경향을 나타냈다. 지방색에서 L*값은 T1 처리구가 높은 경향을 나타냈다.이상의 결과를 보면, 일반대두박에 비하여 탈피 대두박은 흑돼지 생산성과 도체 특성을 개선시킬 수 있는 것으로 사료된다.
A total of 360 Berkshire(hog) weighing 25kg were fed experimental diets containing either dehulled soybean meal(DSBM) or non-dehulled soybean meal(NDSBM) as a major protein source until they reach 80kg. The pigs were then fed the finisher diets either high(3,265 kcal/kg) or low(2,940 kcal/kg) in ME to evaluate the effects of dietary energy level for finisher phase on the growth performances, carcass and meat quality parameter. In growth performance, daily weight gain(kg/day) was higher(P<0.05) in T1 than in other groups. Feed conversion(feed/gain) was lower(P<0.05) in other groups. In carcass parameter, carcass percentage was higher(P<0.05) in T2 than in T1 and T4. Backfat thickness was lower(P<0.05) in T2 than in T1 and T3. The ratio of up B grade in carcass grade tender to be higher in T2 than in other groups. In meat quality, chemical composition was similar between groups. WHC was slighter higher in T1 than in other groups. Shear force was tender to be higher in T1 than in other groups. Hunter L and a in meat color were tender to be higher in T2 than in other groups. Hunter L in backfat color was thender to be higher in T1 than in other groups. The results indicate that growth performance and carcass parameter of Berkshire were improved by the dehulled soybean meal as comparison with non-dehulled soybean meal during growing and finishing periods.
