  • The current study was designed to assess the effects of emulsified sausage supplemented with ginseng saponin on lipid metabolism by applying a rat model. Four groups of 8 rats (5 wk old) were each allocated one of 4 treatments: basal feed (C), and basal feed with 20% sausage powder containing 0% (S0), 2% (S2) and 4% (S4) ginseng saponin. The experiment was conducted for 4 wk. The results did not differ among the treatments with different amounts of sausage (ST), but daily feed intake (p<0.01) and feed conversion (p<0.001) were significantly increased in STs compared to C. Both total serum cholesterol and triglyceride concentrations were significantly (p<0.001) reduced, by 45 and 46%, and 48 and 46%, in S2 and S4, respectively, compared to S0. In the liver, the total cholesterol level was dramatically (p<0.05) decreased according to increasing sausage powder levels. In particular, S4 showed approximately 14% reduction compared to S0 (p<0.05). Liver triglyceride content also showed a similar tendency, where S2 and S4 resulted in 7% and 31% reduction. With regard to fatty acid composition in the liver tissues, palmitic acid (16:0), oleic acid (18:1), eicosanoic acid (20:1), and eicosatrienoic acid (20:3) did not differ among the STs, whereas both linoleic acid (18:2) (p<0.01) and linolenic acid (18:3) (p<0.001) showed significant increases in S2 compared to S0. The current data demonstrated that emulsified sausages supplemented with ginseng saponin effectively reduce total cholesterol and triglyceride concentrations in the serum and liver, and increase unsaturated and essential fatty acid in the liver. These data collectively imply that the sausage improved the overall lipid profile in a rat model, and can be further generalized to the result that emulsified sausage can improve lipid metabolism depending on the products' formula.

  • To investigate the effects of a single bacterium and a mixture of bacteria as probiotics in loperamide-treated animal models, loperamide (3 mg/kg) was administered to SD rats to induce constipation. The individual lactic acid bacterial doses, Enterococcus faecium (EF), Lactobacillus acidophilus (LA), Streptococcus thermophilus (ST), Bifidobacterium bifidum (BB), Bifidobacterium lactis (BL), Pediococcus pentosaceus (PP), and a mixture of the bacteria were orally administered to loperamide-induced constipated rats at a concentration of $10^8CFU/kg$ for 14 days. The weights and water contents of their stools were found to be significantly higher in PP, CKDB (mixture of 5 strains except PP), and CKDBP (CKDB+PP) groups than in the normal (constipation not induced) and the control (constipation-induced) groups (p<0.05). The intestinal transit ratio was significantly higher in all probiotic-treated groups than in the control group, and was the highest in the CKDBP group (p<0.05). The mucosal length and mucus secretion were significantly improved in all probiotic-treated-groups, as compared to that in the control group, and the CKDBP group was found to be the most effective according to immunohistochemistry (IHC) staining and total short chain fatty acid content analysis (p<0.05). Lastly, PP, CKDB, and CKDBP showed relatively higher Lactobacillus sp. ratios of 61.94%, 60.31% and 51.94%, respectively, compared to the other groups, based on metagenomic analysis.

  • This study was undertaken to examine the influence of soluble non-starch polysaccharides on growth performance, mucin secretion, and endogenous amino acid flows in weaner pigs. Different levels (0, 4 and 7.5%) of purified corn arabinoxylan (AX) or barley $\beta$-glucan extract (BG) were substituted for cellulose in a purified diet based on starch, sucrose and enzymatically hydrolyzed casein. All diets contained titanium oxide as an indigestible marker. Each experimental diet was fed to five, 6-wk old weaner pigs for 21 days. Average daily gain (p<0.05) and feed conversion ratio (p<0.01) were improved with dietary inclusion of 7.5% AX and BG, indicating high degradation rates of AX and BG in pigs. Crude mucin contents and endogenous nitrogen flow were increased (p<0.05) with increased levels of AX, but not with BG. Numerical increases in endogenous amino acid flow (EAAF) were observed with increased levels of AX but no definite trend with BG. Endogenous amino acid flow in pigs fed mixed NSP diets (4% BG and 3.5% cellulose) was significantly higher (p<0.05) than those fed 7.5% BG diets. Among diets containing pure sources of soluble non-starch polysaccharides, endogenous amino acid flows were highest in 7.5% AX (p<0.05), intermediate in BG, and lowest in control diet. Increased flows (p<0.01) of threonine, proline and serine in pigs fed 7.5% AX diets are consistent with the increased flow of crude mucin determined in this treatment. In conclusion, mucin and endogenous amino acid flows were increased with dietary inclusion of AX, which could be related to its physicochemical property, particularly its high water-holding capacity. In contrast, $\beta$-glucan, due to its high degradation rate in pig, may be considered as unimportant factor in inducing mucin and endogenous amino acid secretions, at least at levels such as those used in this study.

  • This study examines international tourists 'perceived images and service quality of Korean foods. A survey was conducted to international tourists(Chinese, Japanese, American) visiting Korea. The results of study show that there is a significant difference in several attributes of Korean traditional foods as perceived by international tourists along their nationality. Particularly, American tourists tend to highly evaluate Korean foods as ones good for health. The perceived attractiveness of Korean foods in terms of color and shape is higher for Chinese and Americans than Japanese. A distinct difference is also found in the importance and performance attributes of perceived quality of Korean foods by the nationality of tourists. The results of IPA for the perceived quality of Korean traditional foods show that the restaurant facility and atmosphere are identified as the ones that need to be improved across all the tourists.

  • The weekly ultrasound scanner (US) observations of reproductive organs in a commercial dairy herd with the popular stanchion style management were conducted for over 26 months. Based on reproductive records, the following were evaluated: 1) the effect of postpartum period commencement of US monitoring on herd reproductive efficacy, and 2) the effectiveness of a US monitoring-based diagnosis and subsequent treatments of reproductive disorders on postpartum reproductive efficiency. The reproductive parameters of cows, which were subjected to US monitoring between Days 30-40 (Day 0 = day of parturition), Days 41-50, Days 51-60, and above Day 61, were compared. The reproductive parameters of cows diagnosed as having reproductive disorders (RD) with US monitoring before or after the first artificial insemination (AI) were also compared. It was found that the day of commencement of US monitoring in cows diagnosed with and without RD significantly affected the period towards the first AI and the open period. In particular, cystic follicles and anoestrus detected either before or after the first AI significantly affected herd reproductive efficiency. The implementation of US monitoring improved reproductive efficiency by reducing the open period and increasing the number of milking cows in the herd. The results of this field trial indicate that the postpartum reproductive management of dairy cows with the use of the US monitoring system is one strategy to improve reproductive efficiency, especially in a high-yielding dairy herd reared stanchion management style.

  • Salinity is one of the major and increasing problems in irrigated agriculture in Pakistan. Salinity stress negatively affects the growth and yield of plants guar (Cyanoposisa tetragonoloba). This experiment was conducted to evaluate the effects of ($4dSm^{-1}+13.5(mmol\;L^{-1})^{1/2}$, $5dSm^{-1}+25(mmol \;L^{-1})^{1/2}$, $5dSm^{-1}+30(mmol\;L^{-1})^{1/2}$, $10dSm^{-1}+25(mmol\;L^{-1})^{1/2}$ and $10dSm^{-1}+30(mmol \;L^{-1})^{1/2}$) on biomass yield of guar against salinity tolerance. Maximum biomass yield ($54.50gpot^{-1}$) was produced by $4dSm^{-1}+13.5(mmol\;L^{-1})^{1/2}$ treatment. Biomass produce was reduced with the increase of the salts toxicity. Minimum biomass yield ($30.17gpot^{-1}$) was attained under $10dSm^{-1}+30(mmol \;L^{-1})^{1/2}$. $5dSm^{-1}+25(mmol\;L^{-1})^{1/2}$ treatment exhibited improved outcome i.e. the least diminution % over control (18.66). Salinity cum sodicity showed staid effect on the growth reduction from 18.66% to 44.64%. This reduction fissure was impacted by the toxic effect of salinity and sodicity on Guar growth. Salinity- sodicity behaved toxic impact on the growth reduction from 18.66% to 44.64%. Based on the findings, guar (Cyanoposisa tetragonoloba) grows better at $4dSm^{-1}+13.5(mmol \;L^{-1})^{1/2}$ treatment.

  • The two-level full factorial and mixture design were used to screen ingredient type and to investigate the effects of ingredients on properties of surimi gel from jack mackerel using measurements of breaking forces, deformation values and color. The addition of starch decreased breaking force significantly (p<0.05), but did not affect deformation. The bovine plasma protein (BPP) among non-muscle proteins increased a breaking force and deformation value. However, the dried egg white increased slightly a breaking force, and decreased greatly a deformation value. The breaking force of gel was increased, but deformation value did not change significantly (p<0.05) with adding BPP. The whiteness of gel was slightly improved with the addition of corn starch and BPP. At 78% moisture, the optimum ratios of ingredients were 89.5∼90.0% for alkali surimi, 4.6∼6.0% for corn starch and 4.3∼5.4% for BPP to obtain above 110g for a breaking force, 4.2 mm for a deformation, and 22.5 for a whiteness.

  • The purpose of this research was to analyze the job satisfaction and business attitudes of restaurant owners in order to explore solutions for improving restaurant management. The results were as follows : 1) The motive for starting a restaurant business was vocational aptitude \longrightarrow possibilities \longrightarrow good income : 2) In terms of job satisfaction, most respondents were satisfied with both the work itself and the income. It was also observed that the younger owners were more satisfied with their jobs than the older owners : 3) Increased costs, including labor and food costs, was indicated as the biggest problem in restaurant management. Respondents also perceived labor shortage as one of the most difficult problems. Men were more likely than women to consider the following problems as being more serious: rent, financial problems, taxes, regulation restrictions, menu development and customer complaints. It was found that as the size of the restaurants grew, the respondents perceived the shortage of labor as the hardest part of running a business : 4) Respondents agreed that employing good foodservice workers was the most important part of foodservice management. Owners also believed that they needed more research time for menu and service development 5) To be successful, the restaurant owners paid the most careful attention to food taste. Service, sanitation, and menu development were also emphasized. Respondents stressed the focus on service, good relationships, diligence, and faithfulness in order to be a good restaurant owner. The results of this research suggest that restaurant owners should have more professional conscientiousness to succeed in their own businesses, as well as improve the quality of the foodservice industry. Other important aspects related to the overall improved quality of the foodservice industry are: the continuation of government support, the enlargement of educational opportunities and greater respect for foodservice employees.

  • Background: Indiscriminate use of antibiotics in livestock and poultry farming has caused emergence of new pathogenic strains. The situation has warrented the development of safe and alternative growth promoters and immunity enhancers in livestock. Herbal additives in animal and bird feed is a centuries-old practice. Thus, the present study investigated the efficacy of a standardized formulation of lipophilic turmeric extract containing curcumin and turmerones, (TF-36), as a natural growth promoter poultry feed additive. Methods: The study was designed on 180 one-day old chicks, assigned into three groups. Control group ($T_0$) kept on basal diet and supplemented groups $T_{0.5}$ and $T_1$ fed with 0.5% and 1% TF-36 fortified basal diet for 42 days. Each dietary group consisted of six replicates of ten birds. Body weight, food intake, food conversion ratio, skin colour, blood biochemical analysis and antioxidant status of serum were investigated. Results: Body weight improved significantly in $T_1$ with a 10% decrease in FCR as compared to the control. TF-36 supplementation in $T_1$ enhanced the antioxidant enzyme activity significantly (p < 0.05) with a decrease (p < 0.05) in lipid peroxidation. It also caused a slight yellow skin pigmentation without any change in meat color, indicating the bioavailability of curcumin from TF-36. However, no significant change in the concentration of serum creatinine, total protein and liver enzyme activities were observed, indicating the safety. Conclusion: In summary, we concluded that TF-36 can be a natural feed additive to improve growth performance in poultry, probably due to the better antioxidant activity and antimicrobial effects contributed by the better bioavailability of curcuminoids and turmerones. Besides, curcuminoids and turmerones were also known to be gastroprotective and anti-inflammatory agents.
