A total of 252, 50 week-old Isa-brown laying hens were randomly allotted to 7 groups of 3 replicates. Mustard meal (MM) which is a by-product from mustard processing plant, was dried under the sun or in a gas heated pan. It contained on DM basis 30-32% CP, 19-22% EE and 12-13% CF. The meal from either drying method was incorporated into the diets at 0, 10, 20 and 30% which was equivalent to the substitution levels for soybean meal at 0, 31, 63 and 94%, respectively. All birds were individually kept in battery cages where feed and water were freely accessed throughout 84 days experimental period. It was found that egg production, feed intake, body weight gain and egg weight significantly decreased with the increased MM level. The inclusion of 20% MM did not show a significant difference in egg production and quality from the control, but produced 6-8% lower egg production. Feed intake was linearly decreased with the MM levels, except the 10% sun dried MM group. Fat deposition of the birds fed MM diets significantly decreased, while kidney weight increased when compared with the control group. However, the weight of thyroid glands and spleen trended to be heavier in the MM groups, but this was not significantly different among dietary treatments. It was concluded, MM from both drying methods could be incorporated in laying hen diets at the level of 10% without any adverse effect.

This study was conducted with 262 middle school student(118 boys, 144 girls) to examine their satisfaction, meal preference and improvement of school lunch program(SLP) in Jeonju area. Major plate waste ranked high in soup, fishes, vegetables, Kimch and rice. The overall reason for plate waste were listed as being tasteless and disliking food except for rice. In the case of rice, it because of too big portion size. On the satisfaction with SLP, the lowest satisfaction category was waiting time for meal. The changes after taking part in SLP of students ranked in having a regular meal time(31.4%), lessening to eat snack except for regular meals(18%) and correcting habit about picking favorite food(15.2%), in order. The improvement on SLP of students were listed as more appetite food, various side-dishes, squaring of the western and eastern food and so on. To improve the satisfaction SLP and provide a high quality service, it should be needed to make proper dining space, increase the frequency of survey on complaints and taste of students and reflect the menu plan.

Two experiments were conducted to investigate the effects of molasses supplementation levels to silage materials in ensiling herbal medicine meal on the quality of silage, and its palatability in Korean native goats. In experimentⅠ, molasses were added at the levels of 0, 0.5, and 1.0% to herbal medicine (Deasihotang) meal, with three replicates per each level. They were kept at room temperature for 40 d in glass bottles in order to get silage samples. In experiment Ⅱ, nine 1.5-yr-old Korean native female goats were employed to measure their palatability. In experimentⅠ, lactic acid contents in molasses treatments were significantly (p<0.05) higher, and pH and butyric acid contents was lower than those of non-molasses control treatment. In addition, molasses treatments increased total microbial cell counts in MRS medium for lactobacillus, but decreased total microbial cell counts in PDA medium for fungi. Molasses supplementation to silage materials increased in vitro dry matter disappearance rate. Molasses supplementation tended to increase silage intake in Korean native goat (experiment II), however, the difference was not significant. It is concluded that molasses supplementation to silage materials in ensiling Daesihotang meal could improve its preservability and palatability, the larger the amount the better the quality.

This study examines the relationship between tip amount and its possible antecedents: bill size, the Big Five personality types, meal type, food quality, atmosphere, service quality, consumer gender, server gender, customer hospitality experience, race, and alcohol consumption. A survey of southeastern undergraduate students was conducted to collect information about the customer, server and customer tipping habits. While the analysis suggests that service is an important factor, it shows that other factors affect tip amount. Furthermore, these factors affect tip amounts in many different ways. Some examples of these factors include bill size, alcohol consumption, gender dynamics, meal type, food quality, and personality type. The conclusion suggests the intuition behind these factors by providing a dissection of their meaning and their importance to servers, customers, and managers alike. Purpose: This study tests restaurant customer tipping habits and some personality traits that have received limited previous attention as predictors of tipping. Methods: This study is that the tip amount was self-reported, business students at a university in a large southeastern city of USA were asked to complete a tipping journal. Results: This study was able to replicate the service-tipping relationship. Moreover, this study reiterated that server friendliness is a very powerful tool to increasing tips. Conclusion: This study strongly indicate that service has a positive relationship with tip amount, and also produce a positive relationship with emotional stability and a negative relationship to conscientiousness.

This study investigated the antioxidative activities and quality characteristics of Aster scaber Bibimbap as a home meal replacement with blanching (BASB) or without blanching (ASB) pretreatment. BASB samples at 5.0 g showed higher moisture, crude protein, and ash contents than the control (p<0.05). Color L, a, b-values of samples significantly decreased with increased content of Aster scaber powder (p<0.05). BASB samples showed lower hardness than ASB samples. BASB samples showed higher total phenolic content and DPPH radical scavenging activity than ASB samples. BASB samples showed higher sensory values for color, savory aroma, savory flavor, and aftertaste than ASB samples. Except for glossiness, BASB samples showed higher sensory acceptance scores than ASB samples. Sensory acceptance tests of all samples showed high scores for 'usually like', representing the possibility of successful development of Bibimbap as a home meal replacement, especially that containing blanching pre-treated Aster scaber powder.

In order to increase the nutritional quality of soybean meal (SBM) as an animal feed, Bacillus subtilis TP6, a previously isolated strain from an Indonesian traditional fermented soybean food, Tempeh, was used as a starter organism for solid-state fermentation. In the pre-treated SBM with water content of 60% (v/w), B. subtilis TP6 was grown to a maximum viable cell number of $3.5{\times}10^9CFU/g$. Compared to control, crude protein in Bacillus fermented SBM was increased by 16%, while raffinose, stachyose, and trypsin inhibitors were reduced by 31, 37, and 90%, respectively. The Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis showed that proteins in the fermented SBM were remarkably hydrolyzed into smaller molecular masses, resulting in a decrease in large sized proteins. Our data suggested that B. subtilis fermentation could increase the nutritive value of SBM through reduction of anti-nutritive factors and improvement of protein quality by hydrolysis of soy protein. In addition, B. subtilis TP6 produced a functional ingredient, poly-${\gamma}$-glutamic acid which has various health benefits.

A feeding trial was carried out to investigate the effect of various fish meals as dietary protein source on growth, feed utilization and body composition of Juvenile flounder. Ten experimental diets were prepared to contain different fish meals: 4 kinds of white fish meal (WM-1, 2, 3, 4), 3 kinds of herring meal (HM-1, 2, 3), mackerel meal (MM), WM mixture and HM+MM mixture. Dietary energy and protein levels were designed to be isocaloric ($3.8 kcal g^{-1}diet$) and isonitrogenous ($46\%$) by adjusting the levels of fish meal, wheat flour and squid liver oil. Three replicate groups of fish (initial mean weight: 11.1 g) were hand-fed to visual satiety two times daily for 7 weeks. Survival was not significantly different among all groups. Weight gain of fish fed the HM-1 and HM-3 diets was the highest, but not significantly different from that of fish fed the either WM-2 or HM+MM diets. The lowest weight gain was found in fish fed the W-1 and WM-3 diets. Feed efficiency and protein efficiency ratio of fish fed the WM-2, HM-1, HH-3, MM and HM+MM diets were significantly higher than those of fish fed other diets. Daily feed intake of fish fed the WM-3 diet was highest, but not significantly different from that oi fish fed the either WM-4 or WMM diet. Significant differences were found in contents of moisture, crude protein, crude lipid and ash of whole body of fish. The results of this study indicated that growth of flounder can be affected by dietary fish meal source and quality, and WM-2, HM-1, HM-3 and HM+MM mixture are considered as useful dietary fish meal sources under these experimental conditions.

This study aimed to establish the optimum level of palm kernel meal in the diet of Santa Ines lambs based on the sensorial characteristics and fatty acid profile of the meat. We used 32 lambs with a starting age of 4 to 6 months and mean weight of $22{\pm}2.75kg$, kept in individual stalls. The animals were fed with Tifton-85 hay and a concentrate mixed with 0.0, 6.5, 13.0 or 19.5% of palm kernel meal based on the dry mass of the complete diet. These levels formed the treatments. Confinement lasted 80 days and on the last day the animals were fasted and slaughtered. After slaughter, carcasses were weighed and sectioned longitudinally, along the median line, into two antimeres. Half-carcasses were then sliced between the 12th and 13th ribs to collect the loin (longissimus dorsi), which was used to determine the sensorial characteristics and fatty acid profile of the meat. For sensorial evaluation, samples of meat were given to 54 judges who evaluated the tenderness, juiciness, appearance, aroma and flavor of the meat using a hedonic scale. Fatty acids were determined by gas chromatography. The addition of palm kernel meal to the diet had no effect on the sensorial characteristics of meat juiciness, appearance, aroma or flavor. However, tenderness showed a quadratic relationship with the addition of the meal to the diet. The concentration of fatty acids C12:0, C14:0 and C16:0 increased with the addition of palm kernel meal, as did the sum of medium-chain fatty acids and the atherogenicity index. Up to of 19.5% of the diet of Santa Ines lambs can be made up of palm kernel meal without causing significant changes in sensorial characteristics. However, the fatty acid profile of the meat was altered.
