This study investigated the effects of dietary supplementation of the fermented by products garlic and onion on growth performance, blood composition and cecal microflora in broiler chickens. A total four hundred eighty, day old broiler chickens (Ross) were randomly divided into four groups with four replicates of thirty birds each. The treatment groups were negative group (NC, antibiotic-free diet), positive group (PC, basal diet with 0.05% and 0.03% anticoccidials), fermented of onion by product 1.0% group (T1) and fermented of onion by product 1.0% group (T2). The body weight of broilers fed the diets containing fermented by products garlic was higher than the other treatments during overall period. No significant difference were observed on serum chemical composition and blood corpuscle. In the cecal microflira of broiler, the population of the Lactic acid bacteria was showed the higher in chicken fed diets supplemented with fermented of garlic group than other groups (P<0.05). These results suggest the possibility that fermented of garlic and onion by product could be used as the alternative of antibiotics growth promotor of broiler chickens.

The investigation concerned an effect of the ground charcoal powder and organic acids on the digestibilities of protein and energy or the contents of uric acid, ammonia, creatine and urea in excreta of 113 week-old White Leghorn strain layers. Birds were fed basal (control) diet composed of mainly corn-soybean meal during a week of previous feeding and subsequent experimental diets during 12 weeks of experimental feeding . The experimental diets were the control diet(CON). diet(CPD) substituted 0.5% of the ground charcoal powder with the defatted rice bran of the CON, diet(PWV) added 0.1mM(based on the acetic acid) wood vinegar in the CPD and diet(PFA) added 0.1mM (based on the acetic acid) fermented acetic acid in the CPD. Birds fed CPD excreted significantly(P＜0.05) more fecal nitrogen(FN) and lower urinary nitrogen (UN) than those of birds fed CON. Digestibility of protein was lower significantly (P＜ 0.05) in CPB-fed bird than in bird fed CON. while birds fed CON. PWV and PFA showed similar values. Also urinary nitrogen per nitrogen intake (UN/NI) or absorbed nitrogen (UN/AN) was significantly (P＜0.05) lower in birds fed CPD compared with those in birds fed CON. And birds fed PWV tended to increase UN/NI and UN/AN, while PFA-fed birds excreted significantly (P＜0.05) higher UN/Nl and UN/Ah than those of birds fed CPD diet. The uric acid nitrogen (UAN) per nitrogen intake (UAN/NI) or absorbed nitrogen (UAN/AN) were lower significantly(P＜0.05) in CPD-fed birds and were tended to decrease in birds fed PWV compared with those in birds fed CON and PFA The ammoniacal nitrogen(AMN) per nitrogen intake (AMN/NI) or absorbed nitrogen (AMN/NI) was tended to increase in birds fed experimental diets and was increased significantly(P＜0.05) in birds fed PFA compared with those of birds fed CON. The excretion of creatine and urea nitrogen per nitrogen intake or absorbed nitrogen was shown similar values among birds fed experimental diets Digestibility of energy (DE/GE) was not shown any significant effect of experimental diet and were in the range of 80~84%. But metabolizability (ME/GE or MEn/GE) was increased in birds fed CPD and PWV and was decreased in birds fed PFA compared with those in birds fed CON. Although birds fed PWV showed significantly(P＜0.05) higher ME/GE than bird fed PFA, the MEn/GE were higher significantly (P＜0.05) in birds fed CON and CPD compared with that in birds fed PFA. Fecal energy affects 10~23% in the change of metabolizability though significant effect of fecal energy on the metabolizability were not found. But the effect of urinary energy on the metabolizability of diet was lowered as 2.3~3, 0% and the effect of experimental diets on the metabolizability of diets was due to change of urinary energy which also was originated from the change of uric acid energy.

This study was to examine the lipid metabolism of fermented Rhynchosia nulubilis (FRN) in obese rats. The abnormal content of blood lipids often results in metabolic diseases, such as obesity and hyperlipidemia. Seven weeks female Sprague-Dawley rats were divided into four groups and fed high fat diets for 44 days. Also FRN was administered orally for 44 days at 7.5 ml/kg of body weight of rats. The effects of the lipid metabolism were evaluated by total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), glutamic pyruvate transaminase (GPT) and glutamic oxalacetic transaminase (GOT) levels in sera. The levels of TC, TG, LDL and GPT in FRN-treated groups were lower than those in obese groups. While HDL levels were significantly increased. These results demonstrated that FRN had improving effects of lipid metabolism in the obese rats, suggesting that FRN would be used as an ingredient of the useful functional products.

The authur surveyed the caries experience of 108 preschool children and collected their five-day dietary data, and evaluated the cariogenicity applied to their diets and discussed the relationship between their caries experience and their diet. The results were as follows: 1. As a frequency of consumption of cariogenic foods by degree of retentiveness, highly retentive foods like sugars and dried fruits had been taken once every 3 days, next highly retentive foods like confections and breads had been taken once everyday, slightly retentive foods like ice-creams and fermented milk also had been taken once everyday, and low retentive foods like soft drinks had been taken once every 6 days. 2. The highest caries experienced children ingested more frequently retentive foods like ice-creams, fermented milk and sugars than the lowest caries experienced children. 3. As a potential cariogenicity, the mean number of cariogenic ingestions in a day was 2.26, the mean retentiveness in a day was 5.93, and the mean cariogenicity score per ingestion in a day was 2.51. 4. The highest caries experienced children had higher values in the mean cariogenic ingestions, the mean retentiveness, and the mean cariogenicity score than the lowest caries experienced children.

This study was performed to explore the effects of the fermented functional extracts (FE) on blood glucose and lipid levels in diabetes. FE were created by mixing 9 kinds of plants with sea water and then allowing the mixture to ferment for 1 year. FE were supplemented in the feed of streptozotocin (STZ)-induced diabetic rats at 1%, 3% and 5%. The 1% feeding group showed the lowest weight loss of the three experimental groups. The blood glucose and glycosylated hemoglobin level were significantly decreased in the FE fed rats compared to the diabetic control (DMC) group. The lipid levels in serum were decreased in 1% and 3% FE fed rats in comparison to the DMC group, and there was no significant difference in triglyceride levels due to the FE concentration. The HDL-C level was significantly increased in rats with FE supplemented diets, compared to the DMC group. The levels of lipid peroxides in liver tissue were significantly decreased in FE fed diabetic rats, and the hepatic glycogen content was increased in rats receiving supplements. As a result of these studies, we believe 1% FE may be the optimum level for controlling blood glucose and alleviating hyperlipidemia in STZ-induced diabetic rats.

An 8-week feeding trial was conducted to determine the apparent dry matter and protein digestibility of seven different dietary protein sources by juvenile river puffer Takifugu obscurus. Eight diets containing white fish meal (WFM), brown fish meal (BFM), squid liver powder (SLP), krill meal (KM), leather meal (LM), soybean meal (SM), or fermented soybean meal (FSM) were prepared by mixing a basal diet (BD) with one of the seven test ingredients at a ratio of 7 to 3. Fish averaging $10.8{\pm}0.04g$ were fed the experimental diets in triplicate groups. The apparent dry matter digestibilities of BFM, WFM, FSM, SLP, LM, SM, and KM were 80, 78, 72, 67, 56, 55, and 54%, respectively, while the corresponding apparent protein digestibilities were 96, 96, 93, 92, 89, 88, and 86. The weight gain of fish fed BFM was significantly greater than that of fish fed SM or LM (P<0.05), while it was not significantly different from that of fish fed the BD, WFM, FSM, BFM, SLP, or KM. These results indicated that WFM, BFM, FSM, and SLP are potentially good protein sources for replacing fish meal in river puffer feed.

This study was conducted to investigate the economic analysis of fermented diet made of agricultural and marine by-products such as, dropped apples, persimmon shells, mushroom (Flammulina velutipes) by-products, king oyster mushroom by-products and brewer's grain in Berkshire or crossed pigs. The daily diet cost were decreased by 2.16~3.44%, 3.83~13.35% and 7.47~41.61% when fermented dropped apples diet, fermented persimmon shells diet and fermented mushroom (F. velutipes) by-products diet were fed to Berkshire pigs. The daily feed cost was also decreased by 1.59~4.05% and 59.09~66.90% when fermented king oyster mushroom by-products diet and fermented brewer's grain diet were fed to crossed pigs. Carcass prices were increased by 3.09%, 1.20~3.40% and 1.13% when 2% fermented dropped apples diet, fermented persimmon shells diet and 0.5~1.0% fermented mushroom (F. velutipes) by-products diet were fed to Berkshire pigs. Carcass prices were increased by 2.87~4.19% and 41.31~49.14% when fermented king oyster mushroom by-products diet and fermented brewer's grain were fed to crossed pigs. Therefore, fermented agro by-products diet of dropped apples, persimmon shells, king oyster mushroom, mushroom (F. velutipes) and brewer's grain was expected to improve swine farms income due to decreased diet cost and increased carcass prices in Berkshire pigs or crossed pigs.

Objective: This study aimed to determine the effects of different roughages in total mixed ration (TMR) inoculated with or without coculture of Lactobacillus acidophilus (L. acidophilus) and Bacillus subtilis (B. subtilis) on in vitro rumen fermentation and microbial population. Methods: Three TMRs formulations composed of different forages were used and each TMR was grouped into two treatments: non-fermented TMR and fermented TMR (F-TMR) (inoculated with coculture of L. acidophilus and B. subtilis). After fermentation, the fermentation, chemical and microbial profile of the TMRs were determined. The treatments were used for in vitro rumen fermentation to determine total gas production, pH, ammonianitrogen (NH3-N), and volatile fatty acids (VFA). Microbial populations were determined by quantitative real-time polymerase chain reaction (PCR). All data were analyzed as a 3×2 factorial arrangement design using the MIXED procedure of Statistical Analysis Systems. Results: Changes in the fermentation (pH, lactate, acetate, propionate, and NH3-N) and chemical composition (moisture, crude protein, crude fiber, and ash) were observed. For in vitro rumen fermentation, lower rumen pH, higher acetate, propionate, and total VFA content were observed in the F-TMR group after 24 h incubation (p<0.05). F-TMR group had higher acetate concentration compared with the non-fermented group. Total VFA was highest (p<0.05) in F-TMR containing combined forage of domestic and imported source (F-CF) and F-TMR containing Italian ryegrass silage and corn silage (F-IRS-CS) than that of TMR diet containing oat, timothy, and alfalfa hay. The microbial population was not affected by the different TMR diets. Conclusion: The use of Italian ryegrass silage and corn silage, as well as the inoculation of coculture of L. acidophilus and B. subtilis, in the TMR caused changes in the pH, lactate and acetate concentrations, and chemical composition of experimental diets. In addition, F-TMR composed with Italian ryegrass silage and corn silage altered ruminal pH and VFA concentrations during in vitro rumen fermentation experiment.

Objective : This study was designed to investigate the effects of non fermented Zizyphus. jujuba mixture (mixed fruit and leaf : ZM) and fermented Z. jujuba mixture(FZM) on fed high-fat diet induced hyperlipidemic rats for development medicinal food. Method : The extracts prepared for Zizyphus. jujuba mixture(ZM) and fermented Z. jujuba mixture(FZM) with Lactobacillus plantarum and Saccharomyces cerevisiae. Experimental group was divided into normal control group(NC group) and high fat diet groups. The high fat diet groups fed high fat diet 2 weeks after was sub-divided into high fat diet control group(HC group), high fat diet positive control group(HPC group), non fermented Z. jujuba mixture extract group(ZM group) and fermented Z. jujuba mixture extract group(FZM group). NC and HC group was orally administerd of 0.9% saline, HPC group administerd lovastatin diluted in 0.9% saline at a dose of 10 mg/kg BW, ZM and FZM groups was administerd each extracts diluted in 0.9% saline at a dose of 300 mg/kg BW once a day on a fixed time for 4 weeks. In the present study we measured organ weight, epididymal fat tissue weight, concentration of serum lipids, hepatic lipids, MDA contents in liver tissue and metabolic variables in serum. Results : ZM and FZM suppressed testis weight loss and FZM decreased epididymal fat tissue weight to level of NC group in high-fat diets. ZM and FZM did not influence on serum cholesterol level, but prominently decreased serum triglyceride concentration compared with HC group, and FZM diminished hepatic triglyceride same as serum. ZM and FZM did not impair liver and kidney function and influence positive effects through by suppression of elevation lipid level. Conclusion : These results suggested that Z. jujuba mixture(ZM, FZM) should be useful developing medicinal food for prevention and improvement of hyperlipidemia and FZM is more suitable agent than ZM.

This study was conducted to determine the effects of dietary low grade soybean, fermented with Aspergillus oryzae (FSB 1) or Bacillus subtilis var. natto (FSB 2), on egg production and quality, fat and cholesterol content, and the fatty acid (FA) profile of eggs by lipid layer. A total of 18 Hi-Line strain layers, 22 wk of age, were randomly assigned to three dietary treatments: no fermented soybean (control), control with 15% FSB 1 (C + FSB 1), and control with 15% FSB 2 (C + FSB 2). The rate of egg production and egg weight were evaluated between two periods: one was from the 1st to 4th wk and the other was from the 5th to 8th wk. At the 8th wk, a total of 30 eggs were randomly selected from each treatment group and analyzed for physical quality, fat content, fatty acid composition and cholesterol content. The results showed that egg production was increased in hens fed with diets containing fermented soybeans from the 5th to 8th wk period (p<0.01). A similar tendency was observed through eight weeks' cumulative egg production (p<0.05). There were no significant differences in egg production between the C + FSB 1 and C + FSB 2 treatment groups (p>0.05). Egg weight and other physical properties did not vary between treatment groups (p>0.05). Egg yolks among different treatment groups were similar in fat content, but egg yolks in the C + FSB 1 and C + FSB 2 groups had lower oleic acid (p<0.05), higher linoleic, ${\alpha}$-linolenic, and arachidonic acids (p<0.01), and lower cholesterol content (p<0.05) than those in the control group. In conclusion, supplementation of fermented low grade soybeans might be useful as a functional feedstuff to improve egg production and quality for a healthy human diet.
