To investigate the effect of dietary supplementation with a fermented mixture of bean dregs and wheat bran (FBW) on sow performance. FBW was given to sows during late gestation and lactation; in total, 24 sows were randomly assigned to 4 groups (control diet; 3% FBW diet; 6% FBW diet; 9% FBW diet, n = 6). The weight ratio of bean dregs (wet) to wheat bran was 4:6. Sows were fed different diets from 85 d of gestation until weaning. The results showed that supplementation with FBW increased average daily feed intake (ADFI) during lactation (p < 0.05). FBW supplementation also increased litter weight and milk yield (p < 0.05). The contents of Escherichia coli in the feces of the treatment groups were significantly reduced by FBW supplementation (p < 0.01). FBW supplementation significantly improved the fecal morphology (p < 0.05), alleviating sows' constipation. In conclusion, FBW could increase the ADFI, improve lactation and piglet litter weight in sows and reduce the pathogenic bacterial content in sow feces and constipation.

A nutrition study on weaned pigs using fermented soybean meal was done to determine the effect on growth performance, nutrients digestibility, blood profile and fecal microflora. A total of 100 weaning pigs with an initial average body weight (BW) of 8.27 ± 1.10 kg were randomly allotted into 1 of 2 dietary treatments in a 6-week feeding trial. There were 10 replicate pens in each treatment with 5 pigs per pen. The dietary treatments included: 1) control: Basal diet (CON); 2) fermented soybean meal (FSBM): Basal diet supplemented with 5% fermented soybean meal. The average daily feed intake (ADFI) was significantly improved (p < 0.05) with the dietary supplementation of the FSBM compared with the control meal during phase 2. The dietary supplementation with 5% FSBM had a significant effect (p < 0.05) on gain to feed ratio (G : F) during the overall experiment period. Collectively, the results of this study indicate that dietary supplementation of 5% fermented soybean meal improved the body weight and average daily gain (ADG), ADFI, and feed efficiency of the weaning pigs; however, there were no supplementation effects on total tract digestibility of dry matter (DM), nitrogen, energy, blood profile and fecal microflora.

An experiment was conducted to evaluate apparent (AID) and standardized (SID) ileal digestibilities of crude protein (CP) and amino acids (AA) with 6 soybean products in weaning pigs. A total of 14 weaning barrows with an initial body weight of $6.54{\pm}0.34kg$ were fitted with T-cannula at the distal ileum and allotted to 7 diets containing various soybean products. The soybean products used in the experiment were conventional soybean meal (CSBM), SBM fermented by Aspergillus oryzae GB-107 (FSBMA), SBM fermented by Bacillus subtilis PP6 (FSBMB), UV sterilized SBM fermented by Bacillus subtilis PP6 (UVFSBMB), SBM containing Bacillus subtilis PP6 (PSBM), and soy protein concentrate (SPC). Six corn-based diets were used and each of soybean products was added. All diets contained 5.0 g/kg of chromic oxide as an indigestible indicator and an N-free diet was used to measure basal endogenous losses of CP and AAs. Ileal CP digestibility did not differ by different soybean products. However, SIDs of Ile, Phe and Val were improved in pigs fed the FSBMB, UVFSBMB and SPC diets and the pigs fed the FSBMA diet showed higher SIDs of Phe and Val compared with those fed the CSBM diet (P < 0.05). The FSBMB diet had higher SIDs in most AAs compared with the FSBMA diet (P < 0.05), and higher SIDs of Lys, Ala, Pro, Ser, and Tyr compared with PSBM diet (P < 0.05). However, there was no response of UV-sterilization on the FSBMB in the SIDs of AAs. These results suggest that SIDs of AAs could be improved by the supplementation of fermented soybean products in the diet for weaning pigs but fermentation with Bacillus subtilis is more efficient in improving ileal AA digestibility than that with Aspergillus oryzae. Furthermore, probiotics supplementation in the CSBM and UV-sterilization of the FSBMB had no effects on chemical composition and ileal AA digestibility.

The purpose of this study was to explore the effect of fermented persimmon diet on the meat quality of fattening pigs. Pigs (75 kg) were grouped and housed as 15 animals per pen and 3 replications per treatment. The basal diet (C) was substituted with 3% (T1), 5% (T2) and 10% (T3) of fermented diet. The 180 pigs were fed experimental diet for 42 d and 10 longissimus dorsi (LD) per treatment were collected when each swine reached 105.6 kg of body weight. The crude fat concentration of LD was lower (p<0.05) in treatments, but the pH value of T3 and the shear force values of T2 and T3 were higher (p<0.05) than those of C. The CIE $L^*$ value (lightness) was significantly (p<0.05) higher in T2 and T3 than C, but the CIE $b^*$ (yellowness) of T2 and T3 was significantly (p<0.05) lower than C. The composition of myristic acid and oleic acid was significantly (p<0.05) higher in treatments than in C, while the composition of palmitic acid and stearic acid of treatments were significantly (p<0.05) lower than C in LD. Sensory evaluation of cooked meat as scores of aroma, taste, juiciness and overall acceptability showed higher (p<0.05) in treatments than in C. In conclusion, the dietary of fermented persimmon diet decreased the crude fat concentration, improved the fatty acids composition (increased composition of unsaturated fatty acid and decreased composition of saturated fatty acid) and improved the sensory evaluation of pork meat from fattening pigs.

Protective effects of cheonggukjang fermented with 20% red ginseng (RC) were observed in streptozotocin (STZ)-induced diabetic rats by measuring levels of blood glucose, serum lipid profiles, and hepatic reactive oxygen species generating and scavenging enzymc activities. RC diet was prepared by mixing with AIN-76 diet at the final concentration 2%, and it was fed to STZ-induced diabetic rats for 3 weeks. The RC dict was significantly improved body weight, feed efficiency ratio, levels of serum glucose, and serum and hepatic lipids in diabetes. The significantly elevated O type activity of xanthine oxidase in diabetes was also greatly decreased by the RC diet. The treatment of RC showed the improved hepatic glutathione s-transferase activities in the diabetic animals. The present study indicates that cheonggukjang fermented with red ginseng could ameliorate STZ-induccd diabetic symptoms such as aggravated blood glucose levels, serum lipid profiles, and even the conditions of oxidative stress.

본 연구는 발효 무궁화 추출물과 비발효 무궁화 추출물로 나누어 발효하였을 때, 무궁화 추출물의 항산화 활성과 혈액순환 개선에 미치는 효과가 비발효 무궁화 추출물보다 더 높은지 조사하려고 진행되었다. In vitro 실험에서 항산화 활성을 분석하기 위해서 항산화의 생리활성 물질인 polyphenol과 flavonoid의 함량을 비롯한 DPPH radical 소거효능을 측정한 결과 발효 무궁화 추출물과 비발효 무궁화 추출물 모두에서 polyphenol과 flavonoid의 함량이 농도 의존적으로 높았으며 DPPH radical 소거효능도 역시 농도 의존적으로 높게 나타났다. In vivo 생쥐 실험에서는 보통식이군(NOR), 고지방식이군(CON), 고지방식이+발효 무궁화 추출물 섭취군(FHS), 고지방식이+비발효 무궁화 추출물 섭취군(NFHS)으로 나누어 총콜레스테롤(total cholesterol), 중성지질(triglyceride), 고밀도 지질단백질(HDL cholesterol), 저밀도 지질단백질(LDL cholesterol)을 측정한 결과 발효 무궁화 추출물과 비발효 무궁화 추출물은 총콜레스테롤, 저밀도 지질단백질, 중성지질을 저하시키는 효과가 있는 반면 고밀도 지질단백질을 상승시키는 효과가 있었다. 결론적으로 발효 무궁화는 항산화 생리활성 물질을 많이 함유하고 있어 항산화 효과가 있고 혈액순환을 개선하는데 상당한 효과가 있는 것으로 확인되었다.

고추장은 체중감소 효과를 보였는데 흰쥐를 이용한 식이섭취 실험에서 발효 숙성된 전통고추장이나 공장식 상품고추장은 고지방 식이로 인한 체중 증가를 감소시켜 정상에 가까운 체중을 유지하도록 하였다. 반면에 발효되지 않은 고추장의 경우 고춧가루군과 거의 비슷한 감소효과를 나타내었으며 발효된 전통고추장이나 공장식 상품고추장에 비해서 체중감소효과가 그리 크지 않았다. 발효된 전통고추장은 높은 체중 감소효과와 더불어 부고환 지방 및 신장 주위 지방조직의 총지방, TG, 콜레스테롤의 함량도 낮추는 효과를 나타내었으나 발효되지 않은 고추장식이군은 감소효과가 크지 않아 발효의 유무가 체중감소, 지방조직감소에 큰 변수임을 알 수 있었다.
