Abstract

Today, as the specification of pigs increases, it is important to develop eco-friendly livestock feeds that do not add antibiotics to highly utilizable materials as feed resources, and to produce functional eco-friendly pork and processed products. The purpose of this study was to establish Rubus occidentalis (RO) byproducts containing various amounts of physiologically active substances such as anticancer, anti - inflammation and antioxidant as a raw material for pig feed. The multifaceted efficacy of the RO fermented fodder (ROFF) was confirmed by the nutrient transport factors and antioxidant activity of Berkshire pigs. ROFF was added 0.3% to the general diet and the efficacy was confirmed by feeding diets to Berkshire pigs according to each weight for 43~73 days. As a result, the total cholesterol (TC), LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) levels were decreased or were increased in the castrated male and female Berkshire pigs but not significantly. It was confirmed that the tendency was improved in nutrition physiology. The biochemical levels of female finishing pigs were not significant but increased. In the case of finishing pigs with possibility of pregnancy, it is expected that the nutrition supply for piglet production and will help in the production of the healthy piglet. Transferrin (TFE) levels tended to increase in female growing pig and 110-150 kg finishing pigs. Thus ROFF could minimize the negative effects of iron contents deficiency in female Berkshire pigs. Glutathione peroxidase 1 (GPx1) activity was increased in castrated male and female 110-150 kg finishing pigs. Therefore, ROFF tends to improve the antioxidant capacity. The results of this study suggest that ROFF is one of the most favorable dietary sources when considering the contents of RO in feed. In particular, ROFF could have a positive effect on nutrient transport and iron content of female rather than castrated male Berkshire pigs.

오늘날 양돈의 사양이 증가 함에 따라 부존사료 자원으로서 활용가치가 높은 물질에 항생제를 첨가하지 않고 친환경적으로 제조된 가축용 사료를 개발하여, 기능성 친환경 돈육 및 가공품을 생산하는 것이 중요하다. 이에 따라 본 연구에서는 항암, 항염, 항산화 등 다양한 생리활성 물질이 다량 함유되어 있는 복분자(Rubus occidentalis, RO) 부산물을 양돈사료의 원료로 확립하고자 버크셔 돼지를 대상으로 복분자 발효사료(Rubus occidentalis fermented fodder, ROFF)의 혈액 내 영양 운반인자와 항산화 효능을 연구하기 위해 수행하였다. 시험구는 일반사료(대조구)에 ROFF를 0.3% 첨가하였고, 발효사료의 효능을 확인 하기 위해 각 체중에 따른 버크셔 거세돈 및 암퇘지에게 43~73일간 급여하여 효능을 확인 하였다. ROFF의 복합적인 효능은 혈액 생화학, 철분 및 항산화 분석을 통해 확인하였다. 그 결과 ROFF의 섭취로 인해 거세 자돈 및 육성돈, 암컷 자돈, 육성돈, 및 110-150 kg 암컷 비육돈에서 total cholesterol (TC), LDL-cholesterol (LDL-C), HDL-cholesterol (HDL-C) 모두 감소하거나 HDL-C이 증가하는 경향으로 보아 영양생리학적으로 개선되는 경향을 확인하였다. 암컷 비육돈에서는 생화학적 수치가 모두 증가하는 경향으로 보아 임신 가능성이 있는 비육기의 경우 이러한 수치향상으로 자돈의 생산을 위한 원활한 영양 공급이 예상되며, 건강한 자돈의 생산에 도움이 될 것으로 판단된다. Transferrin (TFE) 함량은 거세돈에서는 변화가 크지 않았으며, 암컷 육성돈 및 110-150 kg 암컷 비육돈에서 ROFF 섭취로 인해 증가하는 경향이 나타남에 따라 ROFF가 철분 결핍으로 인한 부정적인 영향들을 최소화 할 수 있을 것이다. Glutathione peroxidase1 (GPx1)분석 결과 거세 비육돈 및 110-150 kg 암컷 비육돈에서 ROFF의 섭취로 인해 GPx1 활성이 유의적이지는 않지만 크게 증가한 것으로 보아 ROFF가 항산화능을 향상시키는 것으로 판단된다. 본 연구의 결과들을 종합할 때, ROFF의 급여가 전체적으로 시험 개체의 개선 효능에는 영향이 크지 않으나 RO의 함량을 고려 할 때 매우 긍정적인 원료사료 중 하나라 할 수 있으며, 특히 ROFF가 거세돈 보다는 암컷 버크셔의 영양 운반 및 철분 함량 등에 긍정적인 영향을 줄 수 있을 것으로 판단된다.
