  • The objective of the present study was to investigate the effects of growth performance, chemical composition and meat quality parameters by the addition of fermented persimmon shell diets (FPSD). The experimental animals were ninety-six Berkshires. The pigs were allotted at 8 per pen in front-open building with three replicate pens per treatment. Until $61{\pm}1kg$ live weight at 140 days, the animals were fed growing diet, after which, experimental samples were fixed at 0, 3, 5 and 7% FPSD as C, T1, T2 and T3 in the finishing diets. Pigs of $103{\pm}1kg$ live weight were slaughtered by electrical stunning. In growth performance, ADG increased more (p<0.05) in T2 than C and T1. ADFI (kg/day) was higher (p<0.05) in T2 than in other groups. Feed conversion ratio was lower (p<0.05) in T2 than in other groups. On longissimus dorsi muscle (LM), the content of moisture was lower (p<0.05) in T3 than in other treatments. Crude fat increased (p<0.05) by addition of FPSD. pH at 24 h ($pH_{24}$) decreased more (p<0.05) in T2 and T3 than C and T1 by addition of FPSD. WHC decreased (p<0.05) by addition of FPSD. In meat, Hunter $L^*$ and $a^*$ were lower (p<0.05) in C than in other treatments. Hunter $b^*$ was higher (p<0.05) in T3 than in other treatments. In back-fat, Hunter $L^*$ was higher (p<0.05) in C than in other treatments. Hunter $a^*$ was not different in C and T1 but increased (p<0.05) in treatments by addition of FPSD. Hunter $b^*$ increased (p<0.05) by addition of FPSD. In sensory evaluation scores, for fresh meat, the value of meat color was higher (p<0.05) in T2 and T3 than in C and T1. The value of marbling was lower (p<0.05) in C than in other treatments. The value of drip loss was higher (p<0.05) in C than in other treatments and was lower (p<0.05) in T2 and T3 than in other treatments. The results of cooked meat, the value of tenderness was not different in C and T1 but increased (p<0.05) in other treatments. The value of flavor was significantly higher (p<0.05) in T2 and T3 than in C and T1. The value of overall acceptability was increased (p<0.05) by addition of FPSD. Hence we can conclude that addition of FPSD affected growth performance and meat quality parameters, in particular, it improved crude fat, hunter $L^*$ and $b^*$, and sensory evaluation on pork and was also seen to affect $pH_{24}$ and WHC. FPSD can be used for improvement of meat quality parameters.

  • There is a limitation to estimate vitamin $B_{12}$ intake due to lack of data on vitamin $B_{12}$ content in many Korean foods. In this study, vitamin $B_{12}$ content was determined in some soybean or vegetable-fermented foods, edible seaweeds and other frequently consumed foods in Korea by microbioassay using Lactobacillus delbruecki ATCC 7830. The traditional type of Doenjang and Chungkookjang contained 1.85 ${\mu}g/100$ g and 0.69 ${\mu}g/100$ g of vitamin $B_{12}$, respectively, while the factory-type of Doenjang and Chungkookjang contained 0.04-0.86 ${\mu}g/100$ g and 0.06-0.15 ${\mu}g/100$ g. Vitamin $B_{12}$ was not detected in steamed soybeans and Tofu which is a not-fermented soybean product, indicating that vitamin $B_{12}$ in Doenjang and Chungkookjang might be produced during the fermentation process. The Korean-style soy sauce contained 0.04 ${\mu}g$ vitamin $B_{12}$/100 mL, but vitamin $B_{12}$ was not detected in Japanese-style soy sauce and white miso. Commercial Kimchi, a representative Korean vegetable- fermented food, made of Korean cabbage, Yeolmu, or Mustard leaves contained 0.013-0.03 ${\mu}g$ vitamin $B_{12}$/100 g, while Kimchi without red pepper and fermented fish sauce (White Kimchi) did not. Vitamin $B_{12}$ content was very high in some edible seaweeds such as laver (66.76 ${\mu}g/100$ g dry weight) and sea lettuce (84.74 ${\mu}g/100$ g dry weight), and it was 17.12 ${\mu}g/100$ g of dried small anchovy, 1.07 ${\mu}g/100$ g of whole egg, and 0.02 ${\mu}g/100$ g of coffee mix. From these results, it is assumed that Koreans take substantial amount of vitamin $B_{12}$ from plant-origin foods. And, with these data, we will be able to calculate dietary vitamin $B_{12}$ content more correctly than before. In conclusion, soybean-fermented foods, Kimchi, laver and sea lettuce are recommendable as good sources of vitamin $B_{12}$ for vegetarians or Korean elderly on grain and vegetable based diet.

  • This study was conducted to assess the nutritional value and the safety of the fermented food wastes (FFW) made by adding lactobacillus spp. and bacillus spp. at the ratio of 3:7, respectively to food wastes collected everywhere, and also to determine effects on the performances, carcass characteristics and economical profitability when FFW was fed to pigs. For swine trial, FFW was formulate to pellet by utilizing different feed ingredients, and its formulated FFW pellet was used in this feeding trial. Treatments were consisted of different ratios (T1: $100+0\%$, T2: $75+25\%$, T3: $50+50\%$, T4: $25+75\%$, T5: $0+100\%$) of FFW pellet to commercial diet. A total of 20 male pigs were allotted to treatments of five groups of four pigs per pen. Experimental period lasted for 4 months. The nutritional composition of FFW was 56.7, 19.5 and $19.5\%$ for moisture, crude protein and ether extract, respectively. Salt content was $0.39\%$. Noxious microorganisms such as salmonella and E. coli were not detected in FFW, and contents of heavy metal and aflatoxin B1 were lower than the standard. Nutritional values of FFW pellet satisfied over $100\%$ of requirements presented in official Korean feeding standard for swine. Feeding trial for pigs showed that feed intakes were significantly (P<0.05) decreased with increasing levels of FFW pellet. T2 treatment was ideal ratio under the consideration of economical value of feeds and body weight gain of pigs. For carcass characteristics, dressing rate ($\%$) was highest in T3, and carcass grades for T2, T3 and T4 treatments were estimated as 'A'. Feed cost for FFW per kg was ${\won}167.95$, which implies $52\%$ of commercial feed cost (${\won}350/kg$). Thus, this result implied the decreased feed cost in the swine farm. Conclusively, the utilization of food wastes as feed source may lead to the reduced environmental pollution and the practice of organic livestock farming. However, our results showed that excessive amount of fermented food wastes supplementation to pigs might give rise to their reduced palatability and delayed growth.

  • The effects of fermented chaga mushroom (Inonotus obliquus) on the concentrations of serum glucose, insulin, lipids and lipid peroxidation in streptozotocin (STZ)-induced diabetic rats were investigated. Rats were fed a semisynthetic diet supplemented with 50 g/kg chaga mushroom powder (the CM group) and fermented chaga mushroom powder (the FCM group), and no supplemented (the control group) for 3 weeks. The polysaccharide concentrations were CM by $42.9\%$ and FCM by $ 39.1\%$, and the total polyphenol concentrations were CM by $ 0.80\%$ and FCM by $0.91\%$. Feed intakes and water consumption, serum glucose, insulin, triglyceride, and blood urea nitrogen concentrations were significantly lower in the FCM group than in both the CM and control groups. The activities of AST and ALT were also significantly lower in the FCM group than in the control group. No significant differences were detected with regard to the serum cholesterol and creatinine concentrations among the experimental groups. Lipid peroxidations in hepatic homogenate, microsomal and mitochondrial subcellular and pancreas were significantly lowered by the administration of FCM in the STZ-diabetic rats. Hepatic glutathione concentrations, which is closely associated with antioxidant system, was significantly higher in the FCM group than in the control group, indicating a marked effect of FCM administration on the endogenous antioxidant system. However, CM treatment showed a moderate antioxidative activity in the STZ-diabetic rats. Our results indicate that fermented chaga mushroom exert hypoglycemic and antioxidative effects in type 1 diabetes mellitus.

  • 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.

  • This study estimated the effect of fermented persimmon (Diospros kaki L.) extract (FPE) supplement on feed intake, digestibility, nitrogen (N) balance, and rumen fermentation characteristics in sheep. Five male sheep (Corriedale${\times}$Polwarth) with average body weight of $48.6{\pm}1.3\;kg$ were housed in metabolism crates and assigned to a 5${\times}$5 Latin square design with five consecutive 20-d periods which consisted of 14-d adaptation and 6-d data collection. The sheep were fed ad libitum a diet containing concentrate and rice straw (3:7). The five treatments were FPE supplemented at 0 (Control), 5, 10, 20, and 30 g/kg of concentrate. Intakes of dry matter (DM, p<0.01), organic matter (OM, p<0.01), neutral detergent fiber (NDF, p<0.05), acid detergent fiber (ADF, p<0.05), and nitrogen-free extract (NFE, p<0.01) increased quadratically with increasing intake of FPE supplement and maximized (p<0.05) at 10 g/kg FPE. The digestibilities of DM (p<0.05), OM (p<0.05), crude protein (p<0.01), and NFE (p<0.01) increased quadratically with increasing amount of FPE supplement, and sheep fed 5 and 10 g/kg diets had greater (p<0.05) DM, OM, and NFE digestibilites than the Control treatment. By increasing FPE supplement concentration, N intake (p<0.01) and fecal N (p<0.05) increased linearly, whereas retained N (p<0.05) and retained N ratio (p<0.05) increased quadratically. The retained N was maximized (p<0.05) in sheep fed 5 and 10 g/kg diets. The mean rumen pH was not affected by FPE supplement, but there was a quadratic increase (p<0.05) of mean rumen ammonia N concentration and a linear increase (p<0.01) in mean rumen total volatile fatty acid (VFA) and acetate concentrations. The mean concentration of rumen propionate in sheep fed all FPE supplemented diets was greater (p<0.05) than the Control, but the mean ratios of rumen acetate to propionate in sheep fed 5 and 10 g/kg diets were lower (p<0.05) than that of Control sheep. In conclusion, FPE supplemented at 5-10 g/kg of concentrate improved feed intake, the digestibilites of OM and NFE, N metabolism, and rumen fermentation indices of sheep.

  • In this study, we selected some herbal formulation about a series of Chijasi-tang in Dongeuibogam by using web-based open program;Prescription Lineage Graph (http://164.125.206.43/PrescriptionLineageGraph.aspx). And we compared and analyzed the changes of efficacy, major target symptoms of each herbal formulation according to compositional variation of each herbal formulation. Chijasi-tang, first appeared in Sanghanlun, consists of Capejasmine and Fermented soybean, and it is mainly used to treat insomnia due to vexation, heartburn and yellow greasy tongue fur. Capejasmine can clear away irritable feverish sensation in chest by flowing downward the heat, and Fermented soybean can disperse stagnated heat throughout the chest by expelling stagnated heat from the exterior In the case of the heat stagnation caused by relapsing of disease due to overstain, Chisijisil-tang can be used. And if symptom appear more on the upper or exterior than a case of Chisijisil-tang, Seosisi-tang could be more suitable, if half exterior and half interior, Omae-tang could be for it. In addition, if symptom caused by relapsing due to improper diet, Chisijihwang-tang could be proper formulation. In the case of the heat stagnation body inside and jaundice, if it is caused by alcohol, Chijadaehwang-tang could be used for the purpose of urgent purgation, Galchul-tang would be suitable for helping the function of the spleen and the stomach and for treatment of damp-heat of the spleen and the stomach. And if it is caused by pandemic infection, Jangdal-hwan would be good formulation for it. Samhwangseokgo-tang and Yangdokchija-tang could be appropriate formulation for the raging of noxious heat and pathogenic fire caused by febrile disease with toxic yang. Daehwangeum-ja is for severe constipation due to heat-dryness with stagnated fever, Haebaek-tang is appropriate for severe diarrhea due to heat type change of Soeum. According to the result of our investigation, although there are various target causes and symptoms of each herbal formulations, whatever pathogenetic cause is, the stagnated heat in interior side is the basis of symptoms. Therefore, the purpose of including Chijasi-tang in composition of each herbal formulation is treatment of the stagnated heat. For such reason, on the fundamental or ancillary basis of Chijasi-tang plus some herbs for each therapeutic purpose.

  • This study was conducted to investigate the effects of germinated and fermented unmarketable soybean (GFS) on laying performance and egg quality in laying hens. A total of two hundred laying hens were divided into 5 groups (5 treatment $\times$ 4 replication $\times$ 10 birds each) and fed with the experimental diets for 8 wk as follows: control, GFS free; T1, GFS 0.15%; T2, GFS 0.3%; T3, GFS 1%; T4, GFS 2%. The laying performance, egg quality, blood profiles, cecal microbial population, isoflavone content in egg yolk were investigated. There were no significant differences laying performance, relative liver and spleen weights, egg yolk color, eggshell color among groups. Eggshell strength in groups fed with diets containing GFS increased, but not significantly. Eggshell thickness significantly increased in the GFS-supplemented group. No significant differences were observed in the blood profiles and intestinal microflora after supplementation. The decrease of Haugh unit during storage was alleviated by feeding of GFS (p<0.05). The concentrations of malondialdehyde in groups fed with GFS were decreased as compared with control (p<0.05). Isoflavones in the egg yolk were detected in group fed with diet containing 2% GFS. These results showed that unmarketable GFS could be used as a favorable feed additive and feedstuff for production of quality enhanced and isoflavone fortified eggs.

  • This study was performed to investigate cholesterol improvement effects of adding fermented defatted soybean grit (FD) and FD added to 5 or 10% Corchorus olitorius (FDC). Cholesterol adsorption in the FD and FDC group was more than 70%. Apolipoprotein AI and CIII improved in HepG2 cells, and a greater improvement effect was shown in FDC than that in FD. We also investigated the effect of FDC on body lipid metabolism and a high-fat diet for 4 weeks. Rats were divided into control (Con), high-fat (HF), HF treated with 20% FD (HF-FD), and HF treated with 20% FDC (HF-FDC) groups. Plasma total cholesterol and low density lipoprotein-cholesterol concentrations, hepatic total cholesterol, and triglyceride contents were significantly lower in the HF-FDC group than those in the HF group. Additionally, fecal total cholesterol and triglyceride contents increased in rats treated with FDC. Hepatic 3-hydroxy-3-methylglutaryl-coenzyme A reductase activities were significantly lower in the HF-FDC group than those in the HF group.

  • The effects of kwamaegi (0, 6, 12 and 18%, all w/w) on the quality characteristics of Kimchi during fermentation at $10^{\circ}C$ were investigated. The mixtures are denoted KK. The late of decrease in pH during KK fermentation was lower than that of control. The number of total microbes (T) in Kimchi controls fermented for 14 days did not differ, and were in the range of $8.64{\sim}8.68\;log\;CFU/g$, whereas the numbers of lactic acid bacteria (L) in KK were higher than in controls. The L/T(%) was 78.41 in control, 85.76 in 6% KK and $93.68{\sim}94.25%$ in the 16% or 18% KK samples. The hardness of tissue ($2.98{\sim}3.66{\times}10^7\;dyne/cm^2$) in KK fermented for 14 days was higher than that of control ($2.67{\times}10^7\;dyne/cm^2$). The content of alcohol-insoluble substances in KK juice (1.281.08 g/100 g) was lower than that of control (1.45 g/100 g). In sensory evaluation, the appearance and texture of KK were better than those of control. Although some fishy flavor was noted in KK, this did not affect acceptability. Sourness was less, whereas ripened taste and overall acceptability were higher in KK (especially 12% KK) compared to control.
