A trial was performed to study the effects of feeding a diet containing solid-state fermentation rapeseed meal (FRSM) replaced soybean meal (SBM) on growth performance and serum biochemistry parameters of ducks and then to determine the appropriate proportion of soybean meal replacement. The 75% rapeseed meal and 25% blood meal were mixed and inoculated with the Lactobacillus plantarum and Bacillus subtilis. Over the 21-day fermentation, isothiocyanates were reduced from 72.7 to 14.1 mmol/kg. A total of 1,280 fifteen-day-old Cherry Valley ducks were randomly allocated into 4 dietary treatments, 4 replicate groups of 80 ducks each for a 30-day feeding trial. In four treatment groups, fermentation rapeseed meal replaced soybean meal at 0, 33, 67 or 100%, respectively. Results showed that feed intake of ducks fed 100% FRSM was greater (p<0.05) than SBM and partial FRSM in both the finishing period (31-45 d) and entire feeding period (15-45 d). Daily gain increased gradually in the three treatment groups with augmenting FRSM over in the whole study period. In the growing period (15-30 d), compared with the SBM group, phosphorus and calcium content in serum from the FRSM group was improved (p<0.05). Total protein concentration was lower in ducks fed 100% FRSM than SBM and 33% FRSM (p<0.05). Concentrations of IgM were dramatically higher for animals fed 100% FRSM than in the SBM, 33% FRSM and 67% FRSM groups. In the finishing trail stage (31-45 d), only serum IgG content in 100% FRSM group was improved (p<0.05). Therefore, rapeseed meal fermented with Lactobacillus plantarum and Bacillus subtilis is a promising alternative protein source and fermented rapeseed meal can completely replace soybean meal in duck diet and potentially reduce the cost of duck production.

The purpose of this study is to examine current foodservice management practices at free congregate meal service for elderly people. Forty seven meal service centers as well as randomly selected Seoul and Kyunggido area were surveyed and interviewed and results were summarized as follows: The cost of each meal(lunch) was ranged from 1,300 won to 1,500 won and 68% of target centers were severed over 100 meals per day. Meal time for lunch begins from 10:30 am to 12:00 because great portion of elderly didn't take breakfast frequently. 52.3% of centers severed meal 5 times per week, just weekdays. 21.3% of centers employeed dietitian, 63.8% of center employeed cook. 95.7% of center were supported labor force by volunteers. Volunteer was important contribution to free meal service. Utilizing the labor force more effectively is thus a major challenge facing manager in each center. Ideal supporting system of free foodstuff, foodbank was still minor source of securing foodstuff. Most of centers(46 centers)served lunch, only one of them served breakfast and lunch. Government was the major financial sponsor, the second of them was religious organization. The large portions of financial support provided only food cost of total meal service budget. Most of center adapted self-service system. Standardized recipes were not developed and meal preparation was controlled under the experience of volunteers. Recording system of nutrition management, production control, storage and inventory control was not adapted by most of sites. It is suggested that in order to meet the change of the patterns of social and family structure, the service of the center should be offended in urban area and it is necessary to develop systematic management models for the center. It was suggested that not only financial support but also systematical support on management by the local government may be necessary to meet the goal of supply nutritionally balanced food at center.

This study was conducted to investigate the utilization of Sargassum meal in the diet on juvenile ayu (Plecoglossus altivelis) reared in seawater. White fish meal and wheat flour were used as the dietary protein and carbohydrate sources in the control diet. Wheat flour in the control diet was replaced with $5\%$ and $10\%$ Sargassum meal. Three replicate groups of fish average weighing 4.0 g were fed one of three isonitrogenous$(45\%)$ and isocaloric (14.5 MJ /kg diet) diets for 7 weeks. Survival of all groups were above $80\%$. Weight gain, feed efficiency and protein efficiency ratio were not significantly affected by dietary Sargassum meal levels (P>0.05). There were no significant differences (P>0.05) in moisture, crude protein, crude lipid, crude ash and fatty acid compositions of whole-body fish among groups. It is concluded that Sargassum meal could be used as a dietary additive or alternative low-cost dietary ingredient up to $10\%$ for juvenile ayu reared in seawater.

A 15-week growth trial was conducted to evaluate the economical feed formulations for Korean rockfish (Sebastes sehlegeli). Three replicate groups of fish averaging 33 g were fed one of 8 isoproteic ($49\%$) and isolipidic ($8\%$) diets containing various practical ingredients such as fish meal, meat meal, feather meal, blood meal, soybean meal, corn gluten meal, and wheat flour with or without supplemental essential amino acids. A control diet with white fish meal and brown fish meal as the only protein sources was included. Practical ingredients were substituted from $40\%$ up to $65\%$ for portions of the fish meals in the control diet. Essential amino acids (EAA) were added to the diets for balancing EAA composition of each dietary protein source. In addition, these experimental diets were compared with raw fish-based moist pellet containing $50\%$ frozen horse mackerel and $50\%$ commercial binder meal. Results indicated that animal and plant protein sources could substitute for fish meal up to $55\%$ in diet without any adverse effects on growth and chemical composition of fish. Fish growth, body composition, nutrient utilization, and cost of fish production are discussed in relation to nutritional values of the dietary protein sources.

The purpose of this study was to investigate the current status of foodservice management in organizations delivering meal boxes for low-income children during summer vacation. A survey was conducted with persons in charge of meal box production and service of these organizations via mail. Out of 114 questionnaires distributed nationwide, 100 were analyzed(87.8% analysis rate). Over half(53%) of the organizations delivered meal boxes consisting of rice and side dishes while the rest delivered side dishes only. About 81% of the organizations received KRW 3,000 per meal from their local governments and the rest received KRW 3,500. Only 28% of organizations had employed a dietitian. Over one-third(38%) of the respondents were unaware of the official nutritional standard of the foodservice program for low-income children during vacation. Most of the organizations(94%) had menu planned in advance. The average percentage of food cost was 84.1%. Over 40% of the organizations did not keep food samples for sanitation test(43%) and did not take any measures for keeping food temperature during delivery(45%). The organizations delivering rice and side dishes were more likely to be located in cities rather than rural areas and received higher reimbursement rate. The organizations receiving reimbursement of KRW 3,500 or hiring a dietitian were more likely to use standardized recipes, keep food samples for sanitation test, or take measures for keeping food temperature during delivery compared to the counterparts. Respondents reported that increasing reimbursement rate was the most necessary for improving the quality of meal box. This study results showed that the meal box delivery service for low-income children was not properly managed during the vacation, with regards to menu planning and food production. It is recommended that reimbursement rate for meal boxes should be adjusted depending on meal box types and local conditions.

This study was conducted to estimate the effect of dietary alfalfa meal on the contents of egg yolk cholesterol, the levels of egg yolk pigmentation and the performance of laying hens. Alfalfa meal which was alternated wheat bran was supplied 0, 3.5 and 7%, respectively. Total 192 brown laying pullets of 47 weeks old were randomly assigned to the wire cages from July 23 to October 7, 1991 for 10 weeks. The results obtained were summarized as follows ： 1. The egg production was highest at 3.5% alfalfa meal level during the entire period. But there was no significant difference among treatments. 2. Egg weight increased in treatments 3.5 and 7% alfalfa meal supplementation significantly. (P<0.01). 3. Even though there was no significant difference, the daily egg mass was the highest at 3.5% of alfalfa meal level. 4. Daily feed intake was the highest at 3.5% of alfalfa meal level. However, feed conversion rate was the lowest among treatments. 5. The feed cost per kg egg mass in the treatment of 3.5% alfalfa meal was significantly lower than the other treatments. (P<0.05). 6. Shell thickness and shell weight in terms of egg shell quality were increased as the levels of alfalfa meal were increased. But there was no significant difference among treatments. 7, The egg yolk Pigmentation was improved significantly as the level of alfalfa meal was increased (P<0.01). 8.899 yolk cholesterol contents were decreased in the treatments of 3.5 and 7% alfalfa meal supplementation compared with those in the treatment of wheat bran only(P >0.05). The results of this study indicate that 3.5% alfalfa meal level was most effective and economical in laying hen.

The purpose of this study was to compare student's satisfaction with school food service environment to improve the quality of middle school meal service. A survey was conducted of 680 students (boys 246, girls 433) from 6 middle schools providing school meals from October to November 2007. The questionnaires were directly distributed to the subjects for comparison of satisfaction of school meals depending on the eating place. As for the quantity of food, classroom group (3.40) expressed significantly higher satisfaction than cafeteria group (3.16, P < 0.01), but as for the satisfaction on hygiene, classroom group (2.76) showed significantly lower satisfaction than cafeteria group (3.03, P < 0.01). About the satisfaction of school meal environment, classroom group showed more satisfaction on distribution time, eating place, eating atmosphere (P < 0.001). The classroom group showed higher satisfaction than cafeteria group in cases of quantity, diversity of types of soup, dessert, and the cost of school meal. To improve eating place and hygiene of school meal, sufficient cafeteria space and pleasant environment is needed to be established.

An experiment was conducted to investigate the effects of equiprotein replacement of dietary fish meal (FM) with duckweed (DW) and soybean meal (SBM) on the performance of broilers. A total of 112 seven-day-old as hatched broilers were fed on 4 different iso-energetic (2,818 kcal/kg) and iso-nitrogeneous (20.2% CP) diets up to 56 days of age. Diet A was control with 12% FM. In diets B (3% DW + 13.5% SBM), C (6% DW + 11.5% SBM) and D (9% DW +10% SBM). All FM protein of control diet was replaced by DW and SBM. The replacement of dietary FM by DW and SBM depressed feed intake, live weight gain and feed conversion efficiency and increased production cost and thus affected profitability. All those growth parameters had a linear declining trend as the proportion of DW in the diet was increased. It may be concluded that complete replacement of dietary FM by DW and SBM should not be recommended for raising broilers.

This Study investigated kindergarten parents' attitude, satisfaction and demand in the school meal service programs (SMSP). The subjects were 2450 parents that their child attended at kindergarten's SMSP from 16 provinces. To com-pared children's eating habits according to their parent age group and residence area, the percentage of regularly breakfast eating were lower in 'below 30 years old' group and large city residence than 'above 30 years old' group and middle and small city residence. And taking breakfast item was partially different pattern according parent age, 'below 30 years old' group and large city child ate more bread and milk as breakfast than Korean style breakfast with steamed rice and soup and side dish. In the prefer types of school meal service, most prefer types of meal service was fully meal service at kindergarten, $79.1\%$ subjects wanted this type. But 'below 30 years old' group's parent answered 'lunch box brings from home' ratio was higher than 'above 30 years old' group. Most parents accepted the present meal cost and $63.8\%$ of subjects was willing to pay more money to improve the quality of SMSP Twenty-six precent parents was responded that no improvement children's eating habit through SMSP. And they answered the key point of SMSP management was 'cooking sanitation'($65.1\%$) and 'nutrition' ($50.0\%$) and they answered the urgent improvement point at SMSP was 'Improvement taste and quality of meal' ($62.6\%$). Kindergarten parents' attitude about catering service as SMSP as not to prefer, but $10.4\%$ of subjects answered that catering service is ideal meal service type in kindergarten and they expected the advantage of catering service was 'convenience of foodservice'($40.7\%$) and 'support foodservice facilities and labor'($32.4\%$) and they also pointed out disadvantage was 'lower in meal freshness'($53.9\%$) and 'sanitation Problem'($51.9\%$).
