Selenium (Se) apparent absorption and retention in sheep as influenced by diets differing in protein content through soybean meal supplementation was studied. A $3{\times}3$ Latin square design was used with three Japanese Corriedale wethers (45 kg average body weight), three periods, and three dietary treatments. In each period, 7 d dietary adjustment was followed by 5 d total collection of urine and feces. The three dietary treatments were : Diet 1, without soybean meal supplementation (14% crude protein, CP); Diet 2, with 10% soybean meal supplementation (16.5% CP); and Diet 3, with 20% soybean meal supplementation (19% CP). All the diets had a Se supplementation in the form of sodium selenite at 0.2 mg Se/kg dietary DM. The dietary DM intake of the animals was 2% of their body weight. No significant differences were obtained among the three dietary treatments of the Se balance of the animals. However, as percent of Se intake, only urinary Se concentration of Diet 3 was markedly lower (p < 0.05) than the other diets. Fecal Se as percent of Se intake followed the trend of Diet 3> Diet 2 > Diet 1 resulting a Se absorbed as percent of Se intake of 58.9%, 62.3% and 68.2% for Diets 3, 2 and 1, respectively but their differences among each other were insignificant. No significant differences that were observed either on Se retained as percent of intake (Diet 1, 48.2%; Diet 2, 45.2%; Diet 3, 46.0%) or Se retained as percent of Se absorbed (Diet 1, 70.7%; Diet 2, 72.4%; Diet 3, 77.9%). Significant correlation coefficients among the various measures of Se utilization were also observed. Regression analysis showed the following equation: Y = 93.8 - 1.86X (p <0.05, $r^{2}=0.48$), where Y is the Se absorbed as percent of Se intake (%) and X is the dietary protein content (%). This study concludes that Se requirement in sheep is greater when dietary protein content is high.

The effect of soybean meal and barley supplementation of the utilization of rice straw was investigated. Balance trials were conducted with three Japanese Corriedale wethers fed rice straw supplemented with soybean meal and barley at three different levels of protein: low (40 g CP/d, LCP), medium (67 g/d, MCP) and high (94 g/d, HCP). In addition, all the supplements were formulated to contain the same amount of TDN (275 g/d). Voluntary intake of rice straw was not affected by any supplementation, while digestibility of organic matter in sheep given HCO diet was significantly higher (p<0.05) than those on LCP diet. Crude protein, neutral detergent fiber (NDF) and acid detergent fiber (ADF) digestibilities of MCP and HCP diets were significantly improved (p<0.05) over the LCP diet. Average daily gain of the animals under MCP and HCP diets were significantly higher (p<0.05) than those under LCP diet. Differences of rumen pH among the treatments were not significant, while concentration of rumen $NH_3-N$ was significantly higher (p<0.05) for HCP diet than for LCP and MCP diets. Total volatile fatty acids ($VFA_s$) and blood urea nitrogen (BUN) concentrations were significantly higher (p<0.05) in sheep fed MCP and HCP diets than those fed LCP diet, while plasma total protein concentration was not affected by any supplementation. Sheep fed MCP diet had a higher nitrogen retention than those fed LCP and HCP diets. It was concluded that rice straw was utilized better by sheep when SBM and barley were supplemented at the medium level of protein.

The objective of this study was to investigate the effect of levels of cottonseed meal with various carbohydrate sources in concentrate on feed intake, nutrient digestibility, rumen fermentation and microbial protein synthesis in dairy bulls. Four, 6 months old dairy bulls were randomly assigned to receive four dietary treatments according to a $2{\times}2$ factorial arrangement in a $4{\times}4$ Latin square design. Factor A was carbohydrate source; cassava chip (CC) and cassava chip+rice bran in the ratio of 3:1 (CR3:1), and factor B was cotton seed meal levels in the concentrate; 109 g CP/kg (LCM) and 328 g CP/kg (HCM) at similar overall CP levels (490 g CP/kg). Bulls received urea-lime treated rice straw ad libitum and were supplemented with 10 g of concentrate/kg BW. It was found that carbohydrate source and level of cotton seed meal did not have significant effects on ruminal pH, ammonia nitrogen concentration, microbial protein synthesis or feed intake. Animals which received CC showed significantly higher BUN concentration, ruminal propionic acid and butyric acid proportions, while dry matter, organic matter digestibility, populations of total viable bacteria and proteolytic bacteria were lower than those in the CR3:1 treatment. The concentration of total volatile fatty acids was higher in HCM than LCM treatments, while the concentration of butyric acid was higher in LCM than HCM treatments. The population of proteolytic bacteria with the LCM treatments was higher than the HCM treatments; however other bacteria groups were similar among the different levels of cotton seed meal. Bulls which received LCM had higher protein digestibility than those receiving HCM. Therefore, using high levels of cassava chip and cotton seed meal might positively impact on energy and nitrogen balance for the microbial population in the rumen of the young dairy bull.

The lower elementary school grades are an important period in which eating habits are formed. We examined the relationship between eating habits and school meal intake in the lower grades of an elementary school in Seoul. The eating habits were investigated using the Nutrition Quotient (NQ) for children. The school meal intake rates and preferred menus were obtained by automatically scanning the plate before and after meals using an artificial intelligence food scanner. The average school meal intake rate for the 347 subjects was 68.5±12.2%, and the nutrient intakes through the school meals were 353.5±70.0 kcal of energy, 51.8±10.2 g of carbohydrates, 14.6±3.1 g of proteins, 10.3±2.3 g of fats, 87.0±20.0 mg of calcium, and 1.8±0.4 mg of iron. The preferred menus were rice, grilled food, and dairy products, and non-preferred menus were salad, beverages, and stewed food. The eating habits that showed a positive correlation with the school meal intake rate were 'Diverse side dishes (r=0.332, P<0.001)', 'Vegetable side dishes (r=0.166, P<0.01)', 'Kimchi side dish (r=0.230, P<0.001)' and 'Less TV watching and computer game time (r=0.105, P<0.05)'. The NQ score also showed a positive correlation with the rate of school meal intake (r=0.216, P<0.001). The balance score was positively correlated with fruit (r=0.192, P<0.001), and the diversity score had the highest positive correlation with Kimchi (r=0.362, P<0.001). The regularity score was positively correlated with fried food (r=0.114, P<0.05). In conclusion, it was found that elementary school students in the lower grades had a higher school meal intake rate when their eating habits included eating side dishes evenly, and consuming vegetable side dishes and Kimchi.

To promote health status, strategies and interventions to improve nutrition should be based on the proper diagnosis of the subject's eating patterns. The elderly usually have traditional food habits and preferences, and it is very difficult to change them. This study was designed to identify dietary behavior and food preference of the elderly, in order to provide baseline data for the Elderly Nutrition Intervention Program for the Public Health Center. A survey questionnaire was made for use by trained interviewers to query 151elderly people from 5 community elderly centers located in Suwon, Korea. The majority of them ate regularly and partook of all available side dishes. Their major dietary problems were frequent consumptions of salty foods, and eating too quickly. They consumed grains and vegetables regularly, but seldomly ate dairy products, fruits, meat and food prepared with oil. They also tended to eschew ready made processed food, high cholesterol food, and fast food. Also they did not dine out as much as younger people. Desirable eating habit score were not significantly influenced by socioeconomic variables and nutrition-related characteristics. These included nutrition knowledge, Nutritional Risk Index(NRI) and a score of health concerns. However, meal balance scores were significantly higher in the younger group(p<.05), the higher household income group(p<.05). According to stepwise multiple regression analysis, NRI was the most important determinant of a desirable eating habit score for the male elderly, whereas the score of health concerns was mo9st important for female elderly subjects. The greatest predictor of the meal f balance score was nutrition knowledge. The elderly liked sweet tasting food, grains, rice, stews and Korean style soups. They disliked sour food, dairy products, processed food, and bread. The results indicate that the Elderly Nutrition Education Program should focus on increasing consumption of dairy products, fruits and food with oil, prepared by traditional Korean cooking methods. It also suggests that the program planning should consider the socioeconomic status of the elderly, such as income and education level, as well as concern for health.

The purpose of this study was to assess dietary variety by food habits(regularity of meal time, regularity of repast, repast of breakfast, lunch, and supper, number of suppers and night snacks per week, and duration of meal) in 138 female university students residing in Bucheon and its adjacent area. Food habits were assessed via a self reporting questionnaire, and a 3-day dietary recall survey was conducted by interviewing. Dietary variety was assessed by dietary diversity score(DDS), meal balance score(MBS), and dietary variety score(DVS). The average DDS, MBS, and DVS were $3.87{\pm}0.57$, $7.27{\pm}1.48$, and $12.59{\pm}3.14$, respectively. The DDS($2.21{\pm}0.83$) of the breakfast in the group in which the regularity of meal time per week was 5~7 days was significantly higher($p$ <0.01) than the DDS($1.47{\pm}0.96$) of the breakfast in the group in which the regularity of meal time per week was ${\leq}$2 days. The MBS($6.69{\pm}1.43$) of the group in which the regularity of meal times per week was ${\leq}2$ days was significantly lower($p$ <0.01) than the MBS of the group in which the regularity of meal time per week was ${\geq}3$ days. The DDS($2.38{\pm}0.69$) of the breakfast in the breakfast over eating group was significantly higher($p$ <0.001) than the DDS($1.83{\pm}0.83$) of breakfast under eating group. The MBS($6.56{\pm}1.46$) in the breakfast skipping group was significantly lower($p$ <0.01) than the MBS(about 7.6) in other breakfast eating groups, and the DVS ($13.79{\pm}3.21$) in the breakfast over eating group was significantly higher($p$ <0.05) than the DVS($11.53{\pm}2.94$) in the breakfast skipping group. The DDS of breakfast, lunch, and snack were not significantly correlated with the number of suppers per week, but the DDS($2.65{\pm}0.52$) of the supper in the group in which the number of suppers per week was 7 was significantly higher($p$ <0.05) than the DDS($2.22{\pm}0.49$, $2.25{\pm}0.62$) of the supper in the group in which the number of suppers per week was ${\leq}2$, 3~4. The DDS, MBS and DVS were not significantly correlated with the number of suppers per week. The DDS($1.33{\pm}1.25$) of the breakfast in the group in which the number of night snacks per week was 6~7 was significantly lower($p$ <0.05) than the DDS of the breakfast in the group in which the number of night snacks was ${\leq}5$. Also, the DDS($4.42{\pm}0.32$) per day in the group in which the duration of meal was <10 min. was significantly higher($p$ <0.01) than the DDS($3.51{\pm}0.53$) per day in the group in which the duration of meal was ${\geq}30$ min. These findings suggest that nutritional education based on female university students' eating variety and food habits(regularity of meal time, regularity of repast, repast of breakfast, lunch, and supper, number of suppers, and night snacks per week, and duration of meal) may be required to improve dietary variety.

The huge amount of demand for feedgrains from this region could not possibly be met by producing countries from the other regions. In order to fulfill this increasing demand for conventional raw materials, an alternative for the conventional raw materials produced in the Asia and Pacific region is becoming increasingly more important. A potential alternative is concentrates or non-conventional concentrates produced locally in relative abundance in this region. These feedstuffs include feed grains, by-products from the milling, sugar industries, brewing and distilling industries. Vegetable, citrus, and animal by-products from abattoir, feather meal and blood meal are also possibilities. In addition to more widespread use of unconventional feed sources, the following approach is recommended to improve utilization and performance. These include establishing the nutritive value of non-conventional feeds, quality control to minimize variability, proper storage and processing to assure the nutritive value and prevent mycotoxin contamination, properly balance amino acids with protein sources, supplementation with synthetic amino acids and the use of enzymes to increase digestibility. Currently, practical applications for these resources in feed formulation are negligible despite the potential. The socio-economic aspects will dominate the use of these non-conventional concentrates. In the future, the feed industry will resolve the problems in using locally available raw feed materials.

It is said that a mode of dietary behavior changes together with socioeconomic and cultural transformation. Formation of dietary habit of pre-school children influences upon direction of this changes, specially. So, this study was planned to analyst the dietary pattern of pre-school children. A survey was carried out for 3 days of 28 pre-school children with a mean age of 4 years and 3 months. Each child's matter wrote dietary pattern and kinds of food as staple, subsidiary and snack. The results showed that; (1) the average meal frequency a day was 3.1 and interval between meal was 5.1 hours (for breakfast to lunch & lunch to supper) and 12.6 hours (for supper to breakfast), (2) there were 27 different kinds of foods as staple and cereal products consumed the most among those, and 82 different kinds of foods as subsidiary and KIMCHI products were eaten the most rating, (3) the average snack frequency a day was 5.0. There were 76 different kinds of foods as snack, among them cold drink was the best. The present observation suggested that pre-school children had a tendency to take meat regularly, but snack very irregularly, and kinds of foods taken as staple, subsidiary and snack didn't keep the nutritional balance. Parent's concern about dietary behavior of their children is demanded more than ever.

The objectives of the study were to provide the basis for nutrition education for consumers so that they could select nutritious and balanced fast foods and to promote menu items for fast foods franchisers by addressing nutrition and health. Nine franchisers (3 hamburger, 3 noodles and 3 chicken) were surveyed in terms of their nutritional concern for product development, and 360 consumers were interviewed at 36 fast food chains to assess their perceptions of nutrient adequacy of fast foods. The taste of foods was being addressed most when developing menu items in surveyed franchisers but nutrition and variety of menu were being considered least. Hamburger chain franchisers showed greater nutritional concerns in promoting menu items than noodles or chicken chain restaurants. Their nutritional concerns include utilization of nutritional information as promotion of menu item, providing nutrition information of menu item to consumers, and evaluating nutritional balance of their menu items. As a result of INQ evaluation of combined fast food selected by consumers for a meal, the desirable case of both nutritious and adequate in calorie was 14.7%, nutritious but lack in calorie was 44,1%, adequate in calorie was 24.5%, and undernutritious and lack in calories was 21.6%, 45.7% of snack selected by consumers had more calories than needed for a meal.

The objective of this study was to estimate changes on the flood and nutrient intake patterns of men over thirty years old in Jeon-Ju area. The first survey was conducted from December in 1991 to January in 1992, tile second one from January to February in 1994 and the third one from July to August in 1997. The nutrition survey using 24-hour recall method was executed to 303 subjects : 89, 82, 132 in 1991, 1994 and 1997, respectively. Results of the study are as follows : Kimchi, rice, garlic and onions were the most frequently eaten food items. Total daily intakes of foods were 85 : 15, 81 : 19 and 81 : 19 in 1991, 1994 and 1997, respectively. The average numbers of foods per person were 15.7, 20.1 and 21.9 daily in 1991, 1994 and 1997, respectively and tends to increase significantly(p<0.05). The minimum numbers of foods per person were 4, 7 and 9 and the maximum numbers of foods per person were 27, 35 and 39 in 1991, 1994 and 1997, respectively. KDDS(Korean\`s Dietary Diversity Score) is determined by how many among the five food groups (cereals, vegetables, meats, milks, oils groups)were consumed per day. Most subjects earned the KDDS "3" ; 61, 46 and 42% in 1991, 1994 and 1997, respectively. Average daily energy intakes wee 1,62㎉(72% of RDA), 2,063㎉(89% of RDA) and 1,818㎉ (79% of RDA) in 1991, 1994 and 1997, respectively. Energy intake rates of cereals : total energy intake were 65, 59, and 60% in 1991, 1994 and 1997, respectively, which were decreasing. Protein intakes were 58g(72% of RDA), 79g(107% of RDA) and 71g(97% of RDA), respectively and animal protein comprised 46, 53, and 59%, respectively ; which were increased. Fat intakes were 12g, 20g and 20g, respectively and animal protein comprised 38, 46, and 48% ; which were increased. Fat intakes were 12g, 20g and 20g, respectively, of which animal fat comprised 46, 53, and 59%, respectively ; which were increased, too. Malnourished (under 75% of RDA) rates were respectively 64, 34, and 47% in terms of energy ; 64, 31 and 33% in protein ; 67, 51, and 61% in calcium ; 53, 26, and 18% in iron ; 85, 74 and 84% in Vitamin A. Super-nourished(above 125% of RDA) rates were respectively 1, 13, and 3% in energy ; 1, 29, and 21% in protein ; 5, 18, and 7% in calcium ; 16, 31, and 7% in iron ; 16, 31, and 7% in Vitamin A, 42, 76, and 62% in Vitamin C. The percentages of calories from protein : fat : carbohydrate were 14 : 12 : 74, 15 : 16 : 69 and 16 : 17 : 67 in 1991, 1994 and 1997, respectively. KDDS(number of five food groups per day), Meal Balance(number of five food groups per meal), DVS(average numbers of foods per person), amount of foods correlated positively with all the nutrient intakes(p<0.05). KDDS was positively correlated with energy, protein, fat, calcium, thiamin, riboflavin and niacin(p<0.05)in(p<0.05)
