This experiment examined the effects of feeding Aspergillus oryzae (AO) culture to laying hens, on fecal microbial populations, fecal pH and moisture content, egg quality, and metabolizabilities of several nutrients. Sixteen commercial 38-wk-old laying hens were randomly allotted to four diets: control; with 0.15% locally produced AO culture; with 0.3% locally produced AO culture, and; or with 0.3% imported AO. Each treatment consisted of four replicates (cages) containing one bird per cage according to a completely randomized design. After 4 wk, AO were recovered in the feces of birds fed the AO diets, indicating that AO might pass through the fore-gut alive and become active in the hind gut. The number of Lactobacillus spp. in feces was higher in all treated groups than that of the control, indicating that AO would provide a beneficial environment for the Lactobacillus spp. to proliferate in the intestine. The number of fecal E. coli was significantly reduced by the addition of AO. A similar trend was also found for aerobic bacteria. Although not significant, fecal moisture contents tended to be reduced by the addition of AO. Fecal pH was not significantly different among the treatments. The addition of AO did not affect the various economic traits of eggs. Metabolizabilities of gross energy and dry matter measured during the 5th wk were increased by the AO supplementation. It appears that AO culture alone could be used as a probiotic supplement for layers.

This study sought to investigate any additive or interactive effects that soy isoflavones may have on the ecosystem of the gut, which is influenced by fructooligosaccharide (FOS) in colon-cancer model rats. Male Sprague-Dawley rats treated with 1,2-dimethylhydrazine were given experimental diets containing 0, 3, 6, or 9% FOS with or without 0.1% soy isoflavone for 12 weeks. In addition to the effects of FOS dosage on the gut ecosystem, dietary supplementation with soy isoflavone reduced the number of colonic aberrant crypts (ACs). The fecal weight, fecal pH, and gut transit time significantly decreased in a dose-dependent manner in rats fed FOS and the fecal concentration of bifidobacteria was higher in rats fed FOS than in control rats. The fecal output of total short-chain fatty acids, acetate, and propionate was significantly increased by the presence of FOS and was negatively correlated with the number of ACs, whereas the fecal output of butyrate showed no significant correlation with FOS dosage. The addition of soy isoflavone to the diet did not result in any significant differences in gut ecosystem parameters. Therefore, we conclude that the suppressive effect of soy isoflavone on ACs was not associated with the intestinal ecosystem, which was significantly altered by the dosage of FOS.

Objectives The purpose of this study is to report the case of fecal impaction in a child without any abdominal symptoms treated by taking herbal medicine. Methods We examined a 7-year-old girl who had normal bowel movement and defecation per day, and had no particular abdominal symptoms. Abdominal radiography was taken, and unexpected severe fecal impaction was observed throughout the abdominal cavity, filled with intestinal gas and feces. According to the subject's parents, she had no generalized symptoms, such as abdominal pain or distension, and had on a regular diet and normal bowel movement daily. She was treated with herbal medicine (Daeseunggi-tang) for 23 days. While she was on the therapy, numbers, doses, bowel movements, and radiography were checked and recorded. Results During the treatment, her stool was softened, and fecal impaction was relieved as showed by abdominal radiography. Conclusions We have identified that there are cases where subjects have no symptoms of abdominal pain, despite presence of severe fecal impaction. In addition, it was found that Daeseunggi-tang is effective in fecal impaction in childhood.

Coliforms is currently being used as the standard of environmental water qualify to evaluate the level of source water quality especially condition of fecal contamination. However, not properly applied to water quality management. So in this study, in addition to Coliforms, fecal contamination indicator bacteria turk at Feral Coliforms(FC), E. coli, Fecal streptococci(FS), Clostridium and environmental parameters related with it's distribution were investigated on a monthly basis in 6 water intakes of Han River. The mean of BOD, DO, SS and pH, benchmarks of source water management were maintained the second grade of environmental water quality standard applied to Han River but Coliforms exceeded it. Distribution of Coliforms ranged from 1.0×10¹ to 2.7 10/sup 5/ CFU/ml, FC ranged from ND to 5.3×10¹ CFU/ml, E. coli ranged from ND to 9.2×10¹ CFU/ml, FS ranged from ND to 2.5×10¹CFU/ml, they were steepy rise on July and August in common when rainfalls was heavy and water temperature was high, but Clostridium perfringens ranged from 1.7×10¹to 1.7×10¹CFU/ml not fluctuate by month. Statistical analysis of sampling data showed that most significant correlations occurred among FC and Coliforms(r = 0.840), E. coli(r = 0.792), FS(r = 0.687) and environmental parameters(temperature, turbidity, SS, rotor were all r > 0.60) while no significant correlation was observed between ammonia generally recognized fecal contamination indicator and bacteria. Identification of the coliforms showed that Enterobacter, Klebsiella, Citrobacter were comprised of 32%, 24%, 16% respectively, and E. coli were 7% of it. while E. coli was made up 85.9% of FC. The mean value of FC/Coliforms ratio, 5.2(0.1-42) were higher in Amsa, Guui than Jayang. Fecal coliforms, as those are able to reflect more particularly the extent of the fecal contamination, were considered useful in deciding the level of water treatment while monitoring the fecal contamination from the source of water supply. Therefore, it is expected that the water quality is going to be managed more efficiently by using fecal coliforms supplementarily to total coliforms which are current standard item of water-quality environment.

The aim of this study was to assess the effects of dietary complex probiotic (Lactobacillus acidophilus, $1.0{\times}10^7$ CFU/g; Saccharomyces cerevisae, $4.3{\times}10^6$ CFU/g; Bacillus subtilis $2.0{\times}10^6$ CFU/g) on growth performance, nutrients digestibility, blood characteristics and fecal noxious gas content in growing pigs. Ninety [(Duroc${\times}$Yorkshire)${\times}$Landrace] pigs with the average initial BW of 39.75${\pm}$1.97 kg were allocated into three treatments by a randomized complete block design. There were five pens per treatment with six pigs per pen. Dietary treatments include: 1) CON (basal diet); 2) CP1 (basal diet+complex probiotic 0.1%) and 3) CP2 (basal diet+complex probiotic 0.2%). During the entire experimental period of 6 weeks, results showed that addition of complex probiotic at the level of 0.2% to diet increased ADG significantly (p<0.05). Also, digestibilities of DM and N tended to increase, however, no significant differences were observed (p>0.05). Blood characteristics (IgG, Albumin, total protein, RBC, WBC and lymphocyte) of pigs were not affected (p>0.05) by complex probiotic supplementation. Fecal $NH_3$-N was decreased (11.8%) significantly by the addition of complex probiotic (p<0.05), but no effects were observed on fecal acetic acid, propionic acid and butyric acid concentrations (p>0.05). In conclusion, results in this experiment indicated that dietary complex probiotic supplementation had a positive effect on growing pigs performance and could decrease fecal $NH_3$-N concentration.

This study was done to investigate the effects of the incorporation of Achyranthes japonica extracts (AJE) in diet on the production parameters of growing pigs. Exp 1: Total, 105 crossbred pigs (average body weight: 24.47 ± 2.46 kg) were used in a 6-week feeding trial. Pigs (seven replicates, five pigs per pen) were allotted randomly to three treatments. Dietary treatments: CON (basal diet); basal diet with 0.025% AJE, and basal diet + 0.050% AJE). Growth performance, nutrient digestibility, fecal microbial count, and fecal noxious gas were assessed in this study. Average daily gain (ADG), average daily feed intake (ADFI), and gain to feed ratio (G:F) were not affected by the addition of up to 0.05% AJE. In the case of apparent total tract digestibility (ATTD), dry matter (DM), nitrogen (N), and digestible energy (DE) were not changed in 3rd and 6th weeks of the feeding trial through the addition of AJE up to 0.05% in the growing pig diet. In microbial count, Lactobacillus and Escherichia coli count at 3rd and 6th week was similar in all the treatment diets. The inclusion of AJE at levels up to 0.05% in growing pig diet had no effect on the production of NH3, H2S, acetic acid, and CO₂ in the feces. After ending the Exp 1, a total of nine pigs were divided into three treatment groups. Treatment diets were included, TRT1, basal diet + powder quercetin 30 g; TRT2, basal diet + powder quercetin 150 g; TRT3, basal diet + powder quercetin 300g. Rate of absorption in blood was increased with the higher dose of quercetin. The results suggested incorporation of AJE up to 0.05% has no significant effect on ADG, ADFI, and G:F, as well as DM, N, and DE digestibility, fecal microbial count, and fecal noxious gas emission in growing pigs, even though no negative effect was found.

This study explored the effects of milk flavor (MF) supplementation on growth efficiency, nutrient absorption, fecal score, and blood profiles in weaning piglets. A total of 80 (21 days old) crossbred ([Yorkshire × Duroc] × Landrace) healthy weaned piglets with an initial body weight (BW) of 7.05 ± 1.22 kg were randomly allotted to one of two nutritive treatments with 8 repetitions and five pigs (2 female and 3 male) per pen. The experiment was divided into 2 phases (d 0 - 21, and d 21 - 42), and the dietary treatments consisted of TRT1, basal diet, TRT2 and basal diet + 1.0 g·kg^-1 MF. At days 21 - 42 and the overall period, the average daily gain (ADG) and average daily feed intake (ADFI) increased (p < 0.05) by receiving the MF added feed. However, MF inclusion did not impact (p > 0.05) the feed efficiency (G : F) throughout the entire experiment. Piglets consuming the MF supplemented diet showed that the apparent total tract digestibility of dry matter (DM), nitrogen (N) and energy (E) did not vary significantly (p > 0.05) between the treatments. All through the experiment, the fecal score and blood profile of the piglets fed the flavor diet also remained unaffected (p > 0.05). In conclusion, MF addition to the diet of the piglets increased their body weight and had no adverse effects on nutrient utilization, fecal score, and blood profile. Thus, MF addition could improve the performance outcomes of weaning piglets.

Effects of a change in dietary Ca content and an alteration in dietary lipid type on lipid metabolism have been investigated in male Sprague-Dawley rats. The results obtained were summarized as follows ; 1) There was no comparable changes in food consumption and body weight gain among all 9 groups. 2) Serum total lipids and cholesterol were lowest when high Ca-corn all diet was fed, and highest when low Ca-butter diet was fed. 3) The contents of total lipids and cholesterol per g liver and total liver showed no consistent tendency with the dietary treatment. 4) Addition of Ca to the diet caused the significant increase in the dry fecal matter and fecal Ca. And fecal total lipids and fecal cholesterol were much greater if the high-Ca diet was fed than if control and low-Ca diet were fed. It is concluded that Ca and polyunsaturated acids have tendency of hypocholesterolemic effect.

The effect of Bacillus subtilis natto on hindgut fermentation and microbiota of early lactation Holstein dairy cows was investigated in this study. Thirty-six Holstein dairy cows in early lactation were randomly allocated to three groups: no B. subtilis natto as the control group, B. subtilis natto with $0.5{\times}10^{11}cfu$ as DMF1 group and B. subtilis natto with $1.0{\times}10^{11}cfu$ as DMF2 group. After 14 days of adaptation period, the formal experiment was started and lasted for 63 days. Fecal samples were collected directly from the rectum of each animal on the morning at the end of eighth week and placed into sterile plastic bags. The pH, $NH_3$-N and VFA concentration were determined and fecal bacteria DNA was extracted and analyzed by DGGE. The results showed that the addition of B. subtilus natto at either treatment level resulted in a decrease in fecal $NH_3$-N concentration but had no effect on fecal pH and VFA. The DGGE profile revealed that B. subtilis natto affected the population of fecal bacteria. The diversity index of Shannon-Wiener in DFM1 decreased significantly compared to the control. Fecal Alistipes sp., Clostridium sp., Roseospira sp., beta proteobacterium were decreased and Bifidobacterium was increased after supplementing with B. subtilis natto. This study demonstrated that B. subtilis natto had a tendency to change fecal microbiota balance.

Indicator bacteria of fecal pollution were enumerated and compared by various detection methods for influent and final effluent of a sewage treatment plant. Total coliforms were enumerated by four methods including most probable numbers, chromogenic enzyme substrate test, membrane filtration, and plate counts and were about $10^4$ for influent and $10^2{\sim}10^3\;CFU/ml$ for final effluent. Fecal coliforms ranged between $10^3$ and $10^4$ for influent and $10^2\;CFU/ml$ for effluent by chromogenic enzyme substrate test and membrane filtration. Fecal streptococci counts were 1-log less than fecal coliforms counts, $10^2{\sim}10^3$ for influent and $10^1\;CFU/ml$ for effluent. Total coliforms numbers by plate count both in influent and in effluent showed 1-log higher than by the other three methods. Statistical analysis revealed that numbers of total coliforms by plate count in final effluent had the highest average of correlation (r=0.778, p<0.01) compared with those by the other three methods. In addition, total coliforms numbers by plate count showed most significant correlation (r=0.835, p<0.01) with those by chromogenic test which is well-known as its highest recovery efficiency. These results suggest that the plate count would be the optimum detection method for total coliforms in wastewater treatment plants which are the only microbiological standard of final effluent from wastewater treatment plants in the Republic of Korea, considering economic aspects and difficulties in laboratories.
