This study was investigating the anti-obesity effects of diets with a mixture of cheese, red ginseng and fermented mature fruit of Rubus coreanus Miquel. We fed the experimental diets (SC5, SC10) supplemented with 5% or 10% cheese containing of fermented mixture, then orally administered the extract of fermented mixture (RB100, RB300) at a concentration of 100 or 300 mg/kg body weight to SD rats with high fat diet (HFD). The results were as follows: Sample cheese groups decreased visceral fat mass and adipocyte size of stomach compared to that of HFD group. Additionally, lipid droplets of liver in sample cheese groups were smaller than that in HFD group. The serum triglyceride (TG), total cholesterol (tChol), glucose, leptin, and insulin levels in sample cheese group were lower than that in HFD group. But, the serum adiponectin and HDL-cholesterol (cHDL) levels were higher than that in HFD group. These results suggest that fermentation of red ginseng and Rubus coreanus mixed with cheese might be helpful in preventing obesity in high fat diet-fed rats.

A total of 80 pigs [(Landrace ${\times}$ Yorkshire) ${\times}$ Duroc] with an average body weight of $72.9{\pm}2.6kg$ were used in the present study to investigate the effects of fermented whole crop wheat and barley with or without supplementing inoculums throughout the restricted feeding in finishing pigs. There were 4 replicate pens per treatment. Pigs were fed ad libitum throughout the experiment as the control (CON), and the other four groups were restricted to 10% in the CON diet and fed ad libitum fermented whole crop cereals: fermented whole crop barley with inoculums; fermented whole crop barley without inoculums; fermented whole crop wheat with inoculums; and fermented whole crop wheat without inoculums. During the entire experiment, the average daily feed intake (ADFI) decreased in the fermented barley and fermented wheat groups compared to the CON, while no difference was observed in the average daily gain (ADG), feed efficiency (gain : feed ratio, G : F) between the control and fermented whole crop barley, wheat diet group. Dry matter and nitrogen digestibility did not show a significant difference among the treatments. In the blood constituents, concentrations of blood urea nitrogen were significantly lower in pigs fed fermented whole crop barley without inoculum diets compared with the other treatments. In conclusion, restricted feeding with fermented whole crop barley and wheat regardless of the supplementing inoculums showed no significant difference in growth performance compared to the CON. This suggests that there is a possibility that fermented whole crop barley and wheat could replace part of the conventional diets.

This study investigated the physicochemical properties of Pekin duck breast meat obtained from ducks fed diets consisting different types of sipjeondaebo-tang by-products and red ginseng marc with fermented red koji during storage. A total of 180 Pekin ducks (0-day old) were divided into four groups, each consisting of three replicates (15 ducks per pen). This study investigated diets with four types of treatments: control (basal diet),1% blend powder, pelleted 1% blend, and coated pellets of 1% blend; the blend was a mixture of sipjeondaebo-tang by-products powder and red ginseng marc with fermented red koji. There was no significant difference (p>0.05) in duck breast meat pH on storage days 3 and 7, TBARS on storage days 0 through 7, and DPPH radical scavenging on storage days 0 and 7. However, the pH values on storage day 0 and DPPH radical scavenging on storage day 3 were significantly different (p<0.05) in the meats from control and treated diet fed ducks. Especially, on storage day 7, the breast meat from ducks treated with different types of sipjeondaebo-tang by-products and red ginseng marc with fermented red koji showed lower TBARS values and increased DPPH radical scavenging activity compared to the control. In conclusion, addition of different types of sipjeondaebo-tang by-product and red ginseng marc with fermented red koji to 1% blend might be helpful in increasing antioxidant effects and reducing product wastage.

Monascus pilosus로 발효시킨 후 발효 녹차의 첨가식이가 고지방식이 ICR 마우스의 체중과 혈청 지방함량 및 간 조직 항산화계 효소활성에 미치는 영향을 조사하였다. 정상대조군(NC), 고지방식이대조군(HC), 비발효녹차 분말을 2% 첨가한 고지방식이군(CHA) 및 M. pilosus로 발효시킨 후발효녹차 분말을 2% 첨가한 고지방식이군(mCHA)으로 구분하여 7주간 사육하였다. 체중은 CHA군과 mCHA군간의 유의적인 차이가 없으나 HC군에 비하여 각각 24.15 및 29.66%가 감소되었으며 식이섭취량에는 차이가 없었다. 체중 당 간 및 신장의 중량은 CHA군 및 mCHA군이 HC군에 비해 증가하였다. 체중 당 부고환주위지방의 무게는 mCHA군에서 유의하게 감소하였다. 혈청 TG와 의총콜레스테롤 함량은 mCHA군에서 NC군 수준으로 감소하였다. CHA군과 mCHA군의 HDL-cholesterol 함량은 HC군에 비하여 96.55 및 119.32%가 높았다. CHA군과 mCHA군의 CHA군 및 mCHA군의 LDL-cholesterol 함량은 각각 0.67 및 0.41을 나타내었다. 간 조직의 GSH 함량은 HC군에 비하여 CHA군이 11.24%, mCHA군은 23.68%가 높았다. LPO 함량은 CHA군과 mCHA군이 HC군에 비하여 43.70 및 45.38%가 낮았다. CHA군과 mCHA군의 xanthine oxidoreductase D type 효소활성은 HC군에 비하여 각각 18.52 및 33.33%가 감소하였으며 mCHA군은 NC군 수준으로 높았다. XOD O type 효소활성은 CHA군과 mCHA군이 HC군에 비하여 각각 16.67 및 33.33%가 높았다. superoxide dismutase 활성은 CHA군과 mCHA군이 HC군에 비하여 유의차는 없었다. mCHA군의 glutathione S-transferase 활성은 HC군에 비하여 유의적으로 높았으며 특히, mCHA군의 glutathione peroxidase 활성은 HC군의 2.55배, CHA군의 1.5배로 높았으며 NC군과 대등하였다. CHA군과 mCHA군의 ALT 활성 HC군에 비하여 현저하게 낮았다. 간 조직의 현미경 관찰결과, CHA군과 mCHA군에서는 간 세포 내 축적된 지방의 크기가 작은 포말형으로 변화되고, 이로 인해 간 세포판과 동양혈관 형성이 간 소엽단위로 뚜렷하게 구분되었다. 이상의 실험결과로 보아 M. pilosus로 발효시킨 후발효 녹차는 고지방식이에 의해 유발되는 비만과 고지혈증 및 지방간을 예방 혹은 경감시켜줄 수 있는 유효한 가능성을 시사하였다.

This experiment investigated whether yogurt containing fermented pepper juice (FPJY) affects cholesterol level in high fat and high cholesterol diet (HFCD) fed rat. Twenty five Sprague-Dawley male rats of 7 wk were divided into 5 groups, and fed following diets for 9 wk; CON (control diet), HFCD (HFCD), PY (HFCD supplemented with 2% of plain yogurt), LFY (HFCD supplemented with 2% of FPJY), and HFY (HFCD supplemented with 5% of FPJY). In the LFY group, hepatic total lipid level decreased significantly compared to the HFCD group (p<0.05). Serum HDL cholesterol level tended to increase and hepatic total cholesterol level decreased and were comparable to the CON group (p>0.05). In HFY group, body weight and hepatic total lipid level significantly decreased over the HFCD group (p<0.05). Serum and hepatic total cholesterol level, kidney, and body fat weights decreased, and were compared to the CON group (p>0.05). Liver weight decreased as FPJY content was increased. Results suggested FPJY would inhibit organ hypertrophy and accumulation of body fat, hepatic lipid, and cholesterol in HFCD fed rat.

A feeding trial was conducted to evaluate the effect of dietary supplementation with fermented soybean meal by Bacillus subtilis (BFSBM) on growth performance, feed utilization, innate immunity, water quality, and disease resistance of Litopenaeus vannamei. A basal fish meal-based diet was regarded as a control and two other diets were prepared by replacing 30% fish meal with either soybean meal (SBM) or BFSBM. Triplicate groups of shrimp ($0.80{\pm}0.010g$) were fed one of the experimental diets for 6 weeks. No differences were found in final body weight, feed conversion ratio, or survival among all dietary treatments after the feeding trial. Shrimp fed the BFSBM diet had significantly higher phagocytic and phenoloxidase activities than those of shrimp fed the SBM diet. Total ammonia concentrations in culture water during a zero water exchange test tended to decrease in tanks where BFSBM diet was provided. Disease resistance of shrimp to Vibrio harveyi tended to increase in the BFSBM group during 14 days of challenge compared to that in the control (CON) and SBM groups. These results show that dietary supplementation with BFSBM can enhance the innate immunity of Pacific white shrimp and replace at least 30% of dietary fish meal.

Background: Previous studies have shown that both ginseng root and ginseng berry exhibit antiobesity and antidiabetic effects. However, a direct comparison of the efficacy and mechanisms between the root and the berry after oral administration remains to be illuminated. Methods: In this study, we observed the effects of fermented ginseng root (FGR) and fermented ginseng berry (FGB) on obesity and lipid metabolism in high-fat diet induced obese mice. Results: FGR and FGB significantly inhibited the activity of pancreatic lipase in vitro. Both FGR and FGB significantly suppressed weight gain and excess food intake and improved hypercholesterolemia and fatty liver, while only FGR significantly attenuated hyperglycemia and insulin resistance. Both FGR and FGB significantly inhibited the mRNA expression of Ldlr and Acsl1 while FGR also significantly inhibited expression of Cebpa and Dgat2 in liver. FGR significantly decreased the epididymal fat weight of mice while FGB significantly inhibited the mRNA expression of genes Cebpa, Fas, Hsl, Il1b, and Il6 in adipose tissue. Conclusion: Saponin from both FGR and FGB had a beneficial effect on high-fat diet-induced obesity. Compared to FGB, FGR exhibited more potent antihyperglycemic and antiobesity effect. However, only FGB significantly inhibited mRNA expression of inflammatory markers such as interleukins $1{\beta}$ and 6 in adipose tissue.

Objective: This study was to evaluate standardized ileal digestibility (SID) of amino acids (AA) in fermented soybean meal (FSBM) for nursery pigs using both direct procedure and difference procedure when FSBM was added at 20% in diets. Methods: Forty-eight pigs at 9.2±0.9 kg body weight (BW) were individually housed and allotted to 4 treatments. Treatments included NFD (a semi-purified N free diet), FSD (a diet with 20% FSBM), CBD (corn basal diet), and CFD (corn basal diet:FSBM at 80:20). The FSD was used to measure AA digestibility in FSBM using the direct procedure, whereas CBD and CFD were used in the difference procedure. Pigs were fed for 10 days (0.09×BW^0.75 kg per day) and euthanized to collect ileal digesta for TiO₂ and AA. Results: Total endogenous AA loss was 12.1 g/kg of dry matter intake. The apparent ileal digestibility (AID) Thr was greater (p<0.05) and AID His (p = 0.073) and Leu (p = 0.052) tended to be greater using the direct procedure compared with the difference procedure. The SID Thr were greater (p<0.05) in FSBM for nursery pigs calculated using a direct procedure compared with a difference procedure. In addition, SID Lys in FSBM was about 83% to 88% for nursery pigs higher than SID Lys described in National Research Council (2012). Conclusion: The SID of AA in FSBM when included at practical levels using the direct procedure were similar to those from the difference procedure. Considering the SID of AA obtained using both direct and difference procedures, FSBM is an effective protein supplement providing highly digestible AA to nursery pigs. The SID of AA from this study was considerably higher than those previous reported. This study also indicates the importance of including the test feedstuffs at practical levels when evaluating digestibility.
