        Our previous study demonstrated that fermented four-herb combination (Ulgum, Yagmomil, Maesil and Bokbunja) with probiotics (Saccharomyces cerevisiae, Lactobacillus acidophilus, Bacillus subtilis) (hence, this additives was designated PFH) have immune enhancing and antibacterial effects in broiler chickens. The aims of the present study were to investigate the effects of PFH on growth performance and meat quality of broiler chickens. Twenty-day-old Ross broiler chickens were fed with or without PFH for 2 weeks. Body weight gain of the 2% PFH-fed group was significantly increased compared with those of the control group (*P<0.05). Moreover, body weight gain of the 1% PFH-fed group was also showed a increased tendency compared with the control group, although the difference was not significant (P=0.06). However, no significant difference in feed intake was observed among the groups. Feed conversion ratio of the 2% PFH-fed group was significantly decreased compared with those of the control group (*P <0.05). In addition, feed conversion ratio of the 1% PFH-fed group was also showed a slightly decreased tendency compared with the control group, although the difference was not significant (P=0.07). However, no significant differences in the proximate composition (moisture, crude fat, crude protein and crude ash) and the physico-chemical index (cooking loss, shearing force, water holding capacity and pH) were found among the groups. In addition, succulence, tending and flavor in meat of all 3 groups were also not different. Taken together, these findings suggest the possibility that PFH could be used as the alternative of antibiotic growth promoters by improving the performance of broiler chickens.

        This study was conducted to determine the effects of dietary probiotics BiopowderR (BP) on pig performance, carcass characteristics and ammonia concentration in feces. A feeding trial was conducted with a total of 36 growing pigs of an average 29kg body weight. Each treatment had 4 pigs with 3 replications. Pig during grower (26days) and finisher periods (62days) were fed 0.15 and 0.30% concentrations of BP respectively. Body weight gain slightly increased for pigs fed BP during overall periods compared with control, not significantly different. Especially, in growing periods, the body weight gain of BP treatment increased by 10% compared with control (700g vs 775g), in finishing periods, that of BP 0.3% treatment increased by 10% compared with control (890g vs 980g), not significantly different among treatments. Feed intake slightly increased for pigs fed BP in overall periods. During grower periods, the feed intake of BP 0.3% treatment increased by 11.0% more than control, but also not significantly different among treatments. Feed efficiency was slightly improved for pigs fed BP overall periods when compare to the control, but not significantly different among treatments. In feces, average ammonia concentration (ppm) and bacterial count (log cfu/g) were not affected by BP addition. There was no significantly different in carcass weight, fat thickness and carcass grade. In conclusion, supplemental BP tended to slightly improve the performance of pig and did not influenced the concentration of ammonia in feces and carcass characteristics.

        This study investigated the effect of adding poultry litter additive containing probiotics and amino acids to the litter on weight gain in ducks and ammonia content in poultry litter. Nine hundred 1-day-old ducks (Pekin) were randomly distributed into three groups (300 birds per treatment divided into three replicates) using a randomized block design. Treatments were top-dressed on the litter surface at rates of 2 kg poultry litter additives (T1) and 2 kg macsumsuk (T2) per m2, and untreated poultry litter was used as the control. Overall, a significant difference (p<0.05) in weight gains was observed at 3 and 4 weeks, but not at 5 and 6 weeks. After 4 weeks, when compared to other treatments, the addition of poultry litter additive tended to increase the average body weight gain (90-130 g). The ammonia content was affected by all treatments (p<0.05) over time except at 3 weeks, however, compared to other treatments, the poultry litter additive decreased the ammonia content. In particular, the rate of ammonia reduction by the poultry litter additives over time was approximately 20.2%-49.2%. Regarding temperature, a significant difference was observed in all treatment groups (p<0.05), except at 3 weeks. In conclusion, considering poultry litter additives and temperature, the increase in duck weight gain was associated with a decrease in ammonia content in the poultry litter.

        The aim of this study was to investigate the effect of manure additives mixed with probiotics and zeolite on harmful gas production generated by pig slurry. A total of 180 crossbred pigs ([Yorkshire x Land race] x Duroc, live weight 70±3.21 kg) were allotted to a completely randomized design with 3 treatments and 3 replications (20 heads per replicate). The treatments consisted of 0% (control), 0.05% (T1), or 1% (T2) of manure additives mixed with probiotics and zeolite. Manure additives were added weekly to pig slurry pits (2 m × 4.5 m × 1.2 m) on a volumetric basis. For ammonia measured at both 10 cm and 90 cm above the pig slurry pit, a statistical significance (p<0.05) was found in probiotics and zeolite-treated manure additives at weeks 1 – 3, except for week 0. In addition, hydrogen sulfide levels measured at 10 cm above the pig slurry pit were not affected by the manure additive at weeks 0 and 1, but showed a significant statistical difference at weeks 2 and 3 (p<0.05). Therefore, supplementing pig slurry with 0.05% and 0.1% manure additives mixed with probiotics and zeolite was found to be effective in reducing environmental pollution in pig facilities.

        This study was conducted to investigate the efficacy of mixed probiotic on the immunity, productivity index and mortality rate in the broiler. Total of 120 one-day-old Ross broilers chicks were randomly assigned into two treatments (control dietary group and probiotic-treated group) with three replications of each treatment. The probiotic group broiler had a lower mortality rate than control during the experimental period. The productivity index in the probiotic group increased significantly than the control group. The weight of the bursa of fabricius was high in the probiotic-treated group than the control group. Activated the immunity level after fed the probiotic mixed diet compared to the control group. Furthermore, the probiotic diet significantly decreased the saturated fatty the control group. Whereas the probiotic mixed diet increased the unsaturated fatty acid than the control group. Afterward, the diet including probiotic induced positive impact on broilers immunity level. This indicates that a probiotic mixed diet could be protecting the intestine from the invasion of a pathogenic organism. It would be beneficial to the poultry industries by decrease the broiler mortality rate with elevated the immunity.

        In this study, we tried to screen the Bacillus strain having safety probability by isolation of strains from traditional fermented food, measurement of probiotic properties, and the fermentative characteristics of Cheonggukjang. We isolated 400 Bacillus-like isolates from traditional fermented foods. Selected strains examined on the prevalent characteristic such as extracellular enzyme and antibacterial activities, and their safety probability was confirmed by biogenic amine productivity, hemolytic, and harmful substances and enzyme productivity. We selected the 5 strains by analysis of biogenic amine, antibacterial and B. cereus toxic associated gene. Five selected strains were examined on cell surface hydrophobicity, and bile and acid tolerance, and we selected the SRCM100730 as the final strain. SRCM100730 was confirmed B. amyloliquefaciens by 16S rRNA sequencing, and named the B. amyloloquefaciens SRCM100730 (KCCM11966P). Finally, we manufactured Cheonggukjang using SRCM100730 for confirmation of fermentation properties. Manufactured Cheonggukjang did not contain B. cereus, and showed that γ-PGA and extracellular enzyme activities were superior to commercial Chunggukjang. Amino nitrogen content was 544.02 mg% and 26 free amino acid were detected, and the bitterness-related amino acid content was lower than commercial Cheonggukjang. Especially, the amount of GABA was 3 fold higher than commercial Cheonggukjang. These results suggest that SRCM100730 have high availability in commercial probiotics market and fermented food industry.

        Background : Recently, ginseng (Panax ginseng C.A. Meyer.) berry has been used as a health-promoting supplements. Also, Mulberries (Morus alba L.) fruit have been used in traditional herbal medicine to treat and prevent diabetes. In this study, we measured the cytotoxicity after fermentation of the extracts in Panax Ginseng Berry and Mulberry Fruit. Methods and Results : The extracts were prepared by decoction for 3 hours in distilled water (100 g/L). The dried extract was then dissolved in phosphate-buffered saline (PBS) in preparation for use. Cell viability was examined by an MTT assay. RAW 264.7 cells were seeded at 1 × 104/mL densities in 96-well plates. Each grouping had a non-treated group as the control. The extracts were added to each well and incubated for 24 hours at 37°C and 5% CO2. The MTT solutions (5 mg/mL) were added to each well, and the cells were cultured for another 2 hours. The supernatant was then discarded, and 100 μL of dimethyl sulfoxide was added to each well. The optical density was read at 540 nm. Conclusion : Probiotics and prebiotics modulate the composition of human and domestic animal gut microbiota. The beneficial effects may result from suppression of harmful microorganisms or stimulation of organisms which contribute in a positive way to the nutrition and health of human and domestic animal. Recently, fermentation using microorganisms for the production of more effective compounds has been extensively studied. In particular, the novel pharmacological effects of a new compound generated by fermentation have been reported. Some previous studies have demonstrated that Fermented herbal medicine extract showed better bioactivity than normal herbal Plants extract when used at the same concentration.

        The effects of probiotic additions to feed and manure on temperature, humidity and carbon dioxide (CO2) emissions in Hanwoo manure during summer (4 weeks) were evaluated. Fifteen Hanwoo (24-mo-old, 580 ± 20 kg) were housed in individual pens (5 × 8 m) and randomly assigned to 1 of 3 treatments (n = 5 cattle per treatment). Hanwoo were fed experimental rations as follows: control (10 kg roughage + 2 kg concentrate); T1 (10 kg roughage + 2 kg concentrate, 2% probiotics on as-fed basis); and T2 (10 kg roughage + 2 kg concentrate, 2% probiotics on as-fed basis + 7 kg probiotics as top-dressing on the surface of Hanwoo manure). In comparison to the control, the addition of probiotics to feed or feed and manure had an effect (P < 0.05) on temperature and humidity over the 4 weeks, except for humidity at 0 weeks. The only significant difference (P < 0.05) observed in CO2 emission was among all treatments at 3 and 4 weeks (but not at 0 through 2 weeks). These results indicated that use of probiotics as feed and manure additives did not have a significant effect on environmental parameters.
