Purpose: The objective of the present study was to determine whether fermentation can increase the protective effects of blueberry liquid in a high-fat diet-induced obese mice model. Methods: Male C57BL/6J mice were fed a high-fat diet (HD, 60% fat, w/w,), HD supplemented with 10 ml/kg BW/day of blueberry liquid (BHD, blueberry high-fat diet), or HD supplemented with 10 ml/kg BW/day of fermented blueberry liquid (FBHD, fermented blueberry high-fat diet) for 10 weeks. Results: There were significant decreases in the body, epididymal adipose tissue, and liver weights of blueberry-fed groups compared to HD, whereas there were no significant differences in food intake among the groups. Furthermore, blueberry liquid groups, especially fermented blueberry liquid, significantly attenuated the contents of hepatic triglycerides and total cholesterol induced by HD. Serum LDL-cholesterol was significantly lower in the BHD and FBHD-fed groups, whereas FBHD significantly increased the serum HDL-cholesterol level compared to the control. Concentrations of aspartate transaminase, alanine transaminase, and leptins in serum were also reduced by blueberry liquid supplementation. The mRNA expression of hepatic acetyl CoA carboxylase was significantly reduced in both the BHD and FBHD groups compared to HD. Furthermore, FBHD altered the mRNA expression level of hepatic lipolysis genes. Conclusion: In conclusion, these results suggest that blueberry, especially fermented blueberry liquid, may improve obesity-related abnormalities.

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.

The study was conducted to investigate the effect of feeding fermented diet including whole crop barley silage on the odor reduction and microbial population change in feces, and the constipation prevention of pregnant sows. The concentration of phenol was not detected in tapioca, beet pulp, wheat bran and lupin seeds, while that of p-cresol was ranged between 9.62 and 52.11 mg/L showing that lupin was highest and tapioca was lowest. It was determined that tapioca and beet pulp were useful feed ingredients to reduce odor due to their lower contents of phenol and indole compounds. Ten pregnant sows were allocated to control group and fermented diet group in 5 sows in each group. They were fed 3.0 kg DM/d of diets for 28 days. Feces was examined and showed that the feces from the fermented diet group was observed with the higher moisture content and the lower hardness than that of the control diet group and the population of E. coli was decreased and the population of lactobacilus was higher than that of the control diet group. The concentrations of p-cresol and skatole were lower than the detection levels at 33% and 67% among the samples of feces of the control group and at 67% and 100% among the samples of the feces of fermented diet group respectively. Thus it is expected that the odor from the feces of pregnant sows fed the fermented diet could be reduced compared with that of control group. Therefore, it is suggested that feeding fermented whole barley diet to pregnant sows improve the function of intestine and reduce the rate of occurrences of constipation and odor levels.

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.

Effect of kochujang (Korean red pepper soybean paste) on the reduction of body weight and lipid levels of adipose tissues and serum were investigated in the rats fed a high-fat diet. Male Sprague-Dawley rats were fed for four weeks with diets containing either a normal diet (ND, based on the AIN-76TM diet), high fat diet (HFD, supplemented with 20% corn oil in ND), CK diet (10% commercial kochujang in HFD), TK I diet (10% 0 day (non-) fermented traditional kochujang in HFD), TKII diet (10% 6-month fermented traditional kochujang in HFD), or RPP diet (3% red pepper powder in HFD). CK, TK I and TKII in the diet significantly reduced the body weight gain compared to the control (HFD), whereas red pepper powder had no such effect. TKII supplementation in the high-fat diet reduced epididymal and perirenal fat pad weight significantly (p<0.05). Liver total lipid was lower in TKII diet group than other kochujang and RPP diet groups. TKII and CK decreased the content of triglyceride in epididymal and perirenal fat pad that increased by high-fat diet. The cholesterol content of the perirenal fat pad was the lowest in the TKII diet group. TKII was also effective in lowering serum cholesterol level. These results indicated that properly ripened (fermented for 6-month) traditional kochujang exhibited more suppressive effects on body fat gain and lipid levels of adipose tissue and serum than RPP, commercial kochujang and the kochujang without fermentation.
