  • Characteristics of fecal sites of the Siberian flying squirrel Pteromys volans was analyzed based on 132 sites of total 19 places. The fecal sites were more frequently found in winter (43.9%), and then followed by autumn (27.3%), spring (23.5%), and summer (5.3%). With the exception of summer, the fecal sites were more frequently found at the root collar than on the forked tree (p<0.01). Among 132 fecal sites, 88 sites (66.7%) were found on the rood collars and the other 44 sites (33.3%) were posited in the forked trees. Brown or red clay pellets were found at 44 fecal sites (33.4%) and 43 fecal sites (32.6%), and then black and yellow pellets were at 22 fecal sites (16.7%) and 19 fecal sites (14.3%), respectively. Green pellets were rarely found only at 4 sites (3.0%). Feces tend to have bright colors (brown, red clay and yellow) in winter and black in summer. Fecal sites with yellow pellets were much less found in all of the three seasons with the exception of winter, but highly increased in 25.4% in winter. The fecal sites with brown (33.4%) and red clay pellets (32.6%) were most frequently found through the four seasons.

  • Objective: The objective of the study was to determine the influence of varying fibrous diets on fecal characteristics of growing pigs. Methods: A total of 104 pigs (initial weight $18{\pm}2.0kg$) were used in the study. They were housed in individual pens and fed on diets containing maize cob, grass hay, lucerne hay, maize stover, and sunflower husk. These fibers were included at 0, 80, 160, 240, 320 and 400 g/kg. Fecal and urine samples were collected. Results: Fecal output was largest amongst pigs fed on diets containing grass hay and maize stover (p<0.05). Nitrogen content was highest in feces from pigs fed on sunflower husk (p<0.05). Pigs fed on diets containing maize stover and maize cobs produced the largest concentrations of short chain fatty acids. Acetate concentration was high in feces of pigs fed maize stover than those fed grass hay and lucerne hay (p<0.05). As the level of fiber inclusion increased, fecal consistency and nitrogen content increased linearly (p<0.05). Urea nitrogen decreased as the inclusion level increased across all the fibers (p<0.05), with maize cobs containing the largest content of urea nitrogen. As dietary fiber content increased, fecal nitrogen content also increased (p<0.05). Conclusion: It was concluded that different fiber sources influence fecal characteristics, thereby having different implications on pig waste management. It is vital to monitor fiber inclusion thresholds so as to easily manage environmental pollutants such as butyrate that contribute to odors.

  • A total of 96 growing pigs ((Landrace${\times}$Yorkshire)${\times}$Duroc; BW = $26.58{\pm}1.41$ kg) were used in a 6-wk feeding trail to evaluate the effects of fermented chlorella (FC) supplementation on growth performance, nutrient digestibility, blood characteristics, fecal microbial and fecal noxious gas content in growing pigs. Pigs were randomly allotted into 1 of 4 dietary treatments with 6 replicate pens (2 barrows and 2 gilts) per treatment. Dietary treatments were: i) negative control (NC), basal diet (without antibiotics); ii) positive control (PC), NC+0.05% tylosin; iii) (fermented chlorella 01) FC01, NC+0.1% FC, and iv) fermented chlorella 02 (FC02), NC+0.2% FC. In this study, feeding pigs PC or FC01 diets led to a higher average daily gain (ADG) and dry matter (DM) digestibility than those fed NC diet (p<0.05), whereas the inclusion of FC02 diet did not affect the ADG and DM compared with the NC group. No difference (p>0.05) was observed on the body weight, average daily feed intake (ADFI), gain:feed (G:F) ratio, the apparent total tract digestibility of N and energy throughout the experiment. The inclusion of PC or FC did not affect the blood characteristics (p>0.05). Moreover, dietary FC treatment led to a higher (p<0.05) lactobacillus concentration and lower E. coli concentration than the NC treatment, whereas the antibiotic supplementation only decreased the E. coli concentration. Pigs fed FC or PC diet had reduced (p<0.05) fecal $NH_3$ and $H_2S$ content compared with those fed NC diet. In conclusion, our results indicated that the inclusion of FC01 treatment could improve the growth performance, nutrient digestibility, fecal microbial shedding (lower E. coli and higher lactobacillus), and decrease the fecal noxious gas emission in growing pigs when compared with the group fed the basal diet. In conclusion, dietary FC could be considered as a good source of supplementation in growing pigs because of its growth promoting effect.

  • This study was conducted to evaluate the effects of supplementation with bacillus-based probiotic (Bacillus subtilis, $1.0{\times}10^7CFU/g$; Bacillus coagulans, $2.0{\times}10^6CFU/g$ and Lactobacillus acidophilus, $5.0{\times}10^6CFU/g$) on finishing pigs growth performance, nutrients digestibility, blood characteristics and fecal noxious gas content and to determine the optimal addition level of this probiotic preparation. A total of forty eight pigs with an initial body weight (BW) of $90.60{\pm}2.94kg$ were allotted to three dietary treatments (four pigs per pen with four pens per treatment) according to a randomized complete block design. Dietary treatment included: 1) CON (basal diet); 2) BP1 (basal diet+bacillus-based probiotic 0.1%) and 3) BP2 (basal diet+bacillus-based probiotic 0.2%). The experiment lasted 6 weeks. Through the entire experimental period, ADG was improved by 11% (p<0.05) in pigs fed diets supplemented with 0.2% bacillus-based probiotic compared to pigs fed the basal diet. ADFI and gain/feed were not affected by the treatments (p>0.05). Supplementation of bacillus-based probiotic did not affect either DM and N digestibilities or blood characteristics (p>0.05) of pigs. Fecal ammonia nitrogen ($NH_3$-N) measured at the end of experiment was reduced (p<0.05) when pigs were fed the diet with 0.2% bacillus-based probiotic. Fecal butyric acid concentration also decreased significantly (p<0.05) whereas acetic acid and propionic acid concentrations were not affected (p>0.05) when pigs were fed diets with added bacillus-based probiotic. In conclusion, dietary supplementation of bacillus-based probiotic can increase growth performance and decrease fecal noxious gas content concentration.

  • The objectives of this research were to determine the effects of brown rice (BR) on food intake, digestion, energy value, and fecal characteristics. Three replacement levels which BR replaced 0, 15 and 30% of wheat flour were tested. Six female Miniature Schnauzer (8~9 month age, initial mean body weight 5.0 ${\pm}$ 0.3 kg) were assigned to treatments in replicated $3{\times}3$ Latin square design. Total tract digestibilities of DM, OM, acid hydrolyzed fat and gross energy except CP increased linearly (P<0.01), and observed digestible energy and metabolizable energy values also increased linearly (P=0.001 and P=0.006, respectively) with increasing BR replacement level. Wet and dry fecal output decreased linearly (P<0.001, P=0.004) with increasing BR inclusion to the diets and BR 30% treatment reduced wet fecal output up to 21% of that of control. Quadratic (P<0.01) effects was observed in fecal score for dog fed BR and fecal ammonia concentration tended to increase linearly (P=0.07) in response to increasing BR replacement level. It seems that the increase in fecal ammonia concentration may be partially related to the decrease in shortchain fatty acid concentration (P=0.001). This study clearly demonstrates that BR improves nutrients digestibility and fecal characteristics of dog.

  • Beaches in estuaries, bays, and harbors are frequently contaminated with indicators of human pathogens such as fecal indicator bacteria. Tracking down the sources of contamination at these enclosed beaches is complicated by the many point and non-point sources that could potentially degrade water quality along the shore. A mathematical framework was developed to test quantitative relationships between fecal indicator bacteria concentration in ankle depth water at enclosed beaches, the loading rate of fecal indicator bacteria from non-point sources located along the shore, physical characteristics of the beach that affect the transport of fecal indicator bacteria across the beach boundary layer, and a background concentration of fecal indicator bacteria attributable to point sources of fecal pollution that impact water quality over a large region of the embayment. Field measurements of fecal indicator bacteria concentrations and water turbulence at an enclosed beach were generally consistent with predictions and assumptions of the mathematical model, and demonstrated its utility for assessing waste load of non-point sources, such as runoff, bather shedding, bird droppings, and tidal washing of contaminated sediments.

  • 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.

  • The influence of dietary supplementation with blended essential oil on growth performance, nutrient digestibility, blood profiles and fecal characteristics was evaluated in 125 crossed ((Duroc ${\times}$Yorkshire) ${\times}$Landrace) pigs (6.21${\pm}$0.20 kg initial body weight and 21 d average age). The pigs were allotted to the following treatments: i) NC (antibiotic free diet), ii) PC (NC diet+44 ppm tylosin), iii) T1 (NC diet+0.1% essential oil), iv) T2 (NC diet+0.1% essential oil (with 0.3% Benzoic acid)) and v) T3 (NC+22 ppm tylosin and 0.05% essential oil). Average daily gain (ADG) was improved in the T2 group on d 14 (p<0.05). In addition, nutrient digestibility was partially affected (both positively and negatively) by the treatments. Furthermore, the immune system was stimulated and the fecal pH and fecal noxious gases were improved in pigs that received the diets supplemented with essential oil (p<0.05). The appearance and score of diarrhea also tended to be lower in pigs that were subjected to the essential oil treatments. Collectively, the results of this study indicate that supplementation of the diet with blended essential oils could replace treatment with antibiotics to improve growth performance and fecal characteristics.

  • Pollution caused by fecal solids released from recirculating aquaculture systems (RAS) is a growing global concern requiring immediate attention. Thus, this study investigated the physicochemical characteristics of fecal solid feed from RASs used for eel and rainbow trout farming. The concentrations of proteins, lipids, crude ash, and moisture in eel fecal solids were 10.9%, 1.2%, 85.8%, and 72.2%, respectively, while those in rainbow trout fecal solid feed were 20.5%, 3.2%, 70.9%, and 87.0%, respectively. The control group was fed a mixture of sea cucumber and dried sea mud. The protein digestibilities of eel and rainbow trout fecal solids were 25.43% and 23.96%, respectively, while the respective lipid digestibilities were 35.62% and 36.80%, respectively.

  • Purpose: Treatment of chronic constipation and fecal impaction is usually outpatient and requires high or frequent doses of laxatives. However, there are children who fail outpatient treatments, sometimes repeatedly, and are ultimately hospitalized. We sought to compare the characteristics of the children who failed outpatient treatment and needed inpatient treatment vs those who achieved success with outpatient treatment, in an effort to identify attributes that might be associated with a higher likelihood towards hospitalization. Methods: In this retrospective cohort study, we reviewed the medical records of all patients aged 0 to 21 years, with chronic functional constipation and fecal impaction seen in the pediatric gastroenterology clinic over a period of 2 years. Results: Total of 188 patients met inclusion criteria. While 69.2% were successfully treated outpatient (referred to as the outpatient group), 30.9% failed outpatient treatment and were hospitalized (referred to as the inpatient group). The characteristics of the inpatient group including age at onset of $3.6{\pm}3.6years$ (p=0.02); black ethnicity (odds ratio [OR] 4.31, 95% confidence interval [95% CI] 2.04-9.09); p<0.001); prematurity (OR 2.39, 95% CI 1.09-5.26; p=0.02]; developmental delay (OR 2.20, 95% CI 1.12-4.33; p=0.02); overflow incontinence (OR 2.26, 95% CI 1.12-4.53, p=0.02); picky eating habits (OR 2.02, 95% CI 1.00-4.08; p=0.04); number of ROME III criteria met: median 4, interquartile range 3-5 (p=0.04) and $13{\pm}13.7$ constipation related prior encounters (p=0.001), were significantly different from the outpatient group. Conclusion: Identification of these characteristics may be helpful in anticipating challenges and potential barriers to effective outpatient treatment.
