Abstract

This study was intended to provide basic information which might be useful in increasing added values to the pork from Korean native black pigs (KNP), through comparative evaluation on carcass characteristics and meat qualities between KNP and four exotic breed groups including Duroc (DD), Landrace (LL), Yorkshire (YY), and LYD-cross (1/4LL 1/4YY, 1/2DD), and the results were summarized as follows. Live weight carcass weight, dressed meat weight, skin weight, fat weight and bone weight of KNP were significantly (p<0.05) lower than those of DD, LL, YY and LYD-cross. Carcass yield and dressed meat yield were also significantly (p<0.05) lower in KNP than other 4 groups, however, total fat, skin, bone, kidney and kidney fat in percentage were significantly (p<0.05) higher for KNP than others. Dressed meat yield was highest for YY, followed by LYD-cross and KNP. Weight of belly was 6.12, 9.43, and 9.52 kg for KNP, YY and LYD-cross, respectively. Percent belly of KNP was $11.11\%$ while other groups ranged from 11.5 to $12.2\%$ Shear force value was not different among the treatments. KNP had significantly (p<0.05) lower water holding capacity (WHC), and cooking loss, but significantly (p<0.05) higher in juiciness comparatively. KNP had significantly (p<0.05) higher $a^{*}$ value while DD had significantly (p<0.05) lower than other breeds.

본 연구는 재래흑돼지와 개량종 돼지들과의 도체 및 육질 특성을 비교 평가하여 표준화를 통해 부가가치를 높여 품질을 고급화 할 수 있는 기초자료를 제시할 목적으로 재래흑돼지와 개량종 돼지인 듀록종(DD), 랜드레이스종(LL), 요크셔종(YY) 그리고 삼원교잡종(LYD)을 시험에 공시해 품종간 처리구별 도체 및 육질 성적을 비교 분석하였다. 본 연구 결과, 재래흑돼지의 생체중, 도체중, 거래 정육 생산량, 가죽, 지방 및 뼈의 생산량이 개량종 처리구에 비해 유의적으로 낮게 나타났으며, 재래흑돼지의 도체율과 정육률도 개량종 4처리구에 비해 유의적으로 낮은 경향이었으나(p<0.05), 총지방 생산율, 가죽, 뼈, 신 및 신지방의 생산율은 재래흑돼지가 개량종에 비해 유의적으로 높았다(p<0.05). 재래흑돼지는 개량종과 비교해 모든 부위에서 낮은 정육량을 보였으며, 품종간에는 YY종이 가장 높았고, 다음 LYD종이 높았으며, KNP가 가장 낮았다. 삼겸살 정육량은 KNP, YY종, LYD종이 각각 6.12, 9.43, 9.52 kg으로 나타났으며, 재래흑돼지의 삽겹살 정육률은 $11.11\%$이었으며, 개량종은 $11.5\~12.2\%$를 나타내었다. 또한 전단가는 품종간 유의적인 차이를 보이지 않았으나 보수력과 가열 감량은 재래흑돼지가 낮은 경향을 보인 (p<0.05) 반면, 다즙성은 근내 지방함량이 높은 관계로 유의적으로 높았다(p<0.05), 육색의 $a^{*}$값은 KNP가 가장 높았고 (p<0.05), DD종이 가장 낮았다(p<0.05).
