Abstract

This study was carried out to investigate the feeding effect of by-products such as ginseng loaves(GL) and stem (GS) which had about 8% of crude saponin on pork carcass and meat quality characteristics when they were fed for 40 days. The ginseng leaves and stem were added in feed and the pigs were slaughtered at 10, 20, 30 and 40 days. The chilled carcass weight and trimmed fat contents were higher(86.50 kg) in the pork fed for 40 days. The yields of fore legs were higher in pork fed for 10 days(P<0.05) and there was no different in the yields of the other portion cuts such as shoulder, rib, loin, belly, hind legs and tenderlons. The incidence of percentages for grade A and B decreased as the feeding periods increased up to 40 days. The backfat thickness was lowest in carcasses from pigs fed up to 20 days(P<0.05). The L values were highest in pork fed up to 30 days(50.22) and lowest(46.91) for pork fed 10 days. The incidence of PSE pork was low in pork fed for 20 days when compared to other feeding days. Cooking loss was lowest and water holding capacity(WHC) was highest in pork fed GL and GS stem, respectively. However, the analysis for accumulation contents of saponin and functionality in pork fed GL and GS is needed in the future research.

인삼 잎과 줄기의 crude saponin 함량은 약 8% 정도로 그 가치가 높아 사료로 이용하기 위한 방법으로, 인삼 잎과 줄기 부산물의 추출액을 사료에 3% 혼합하여 생산한 사료를 돼지에 20일, 30일 및 40일간 급여하여 생산한 돼지의 도체 및 육질특성을 조사한 결과 다음과 같다. 급여수준에 따른 돼지의 도체특성에 있어서 정육율은 20일 급여구가 65.55%로 가장 높았으며, 대조구, 30일 급여구, 40일 급여구 순으로 나타났으며, 제거 지방율은 40일 급여구가 18.32%로 가장 높았다. 부분육벽 생산율은 목심, 갈비, 등심, 삼겹살, 뒷다리, 안심부위에서는 처리간에 유의적인 차이가 나타나지 않았으나, 앞다리 부위에서는 20일급여구에서 가장 높은 11.12%로 나타났다(P<0.05). 처리별 도체등급 A 및 B 등급 출현율은 30일과 40일 급여구에서 오히려 낮게 나타났으며, 등지방 두께는 20일 급여구가 가장 적었다(P<0.05). 처리구별 명도(Hunter L)는 30일 급여구가 50.22로 가장 높은 값을 보였고, 20일 급여구가 46.91로 가장 낮은 값을 보였다. PSE 출현율은 20일 급여구가 가장 낮게 나타났고. pH는 인삼부산물을 40일 급여한 처리구에서 5.72로 가장 높게 나타났다(P<0.05). 인삼부산물 급여 돼지 등심육의 물리적 특성을 조사한 결과, 전단력은 유의적인 차이는 없었으며, 가열감량은 인삼부 산물 급여시 감소하는 경향으로 나타난 반면, 보수력은 인삼 부산물 급여시 증가하는 경향을 보였다(P<0.05). 이상의 결과에서 인삼부산물 추출액 급여에 의한 돈육 생산시 도체특성 및 부된육 수율에서 인삼부산물 급여에 의한 차이는 없었으나, pH는 인삼부산물을 40일간 급여한 처리구 에서 유의적으로 높았으며, 가열감량 및 보수력은 인삼부산 물을 각각 40일 또는 30일간 급여한 처리구가 다른 처리구에 비해 좋은 것으로 나타났다.
