  • A total of 120 pigs were used to investigate the effects of yucca extracts on the growth performance, nutrient digestibility and excretion of growing pigs fed different levels of dietary protein. Pigs were allotted into $2{\times}3$ factorial design by the supplementation with yucca extract (YE, 0 and 120 mg/kg) and 3 levels of dietary protein (16, 18, 20%). During the whole experimental period (18 to 52 kg body weight), there were no significant differences in ADG, ADFI or F/G by YE addition or different protein levels among treatments (p>0.05). Overall, although addition of YE to the diet and elevation of protein level showed better ADG, there were no significant differences in growth performance among treatments. Pigs fed diets with YE showed significantly (p<0.05) higher dry matter (DM), crude ash (CA) and crude protein (CP) digestibility than did the others during the growing period. Concerning the levels of dietary protein, only the CP digestibility was significantly higher in pigs fed high protein diet. Pig fed the low protein diet without YE showed a significantly low CP digestibility (p<0.05). No significant differences were found in crude fat (CF), calcium (Ca) and phosphorus (P) digestibilities regardless of YE supplementation or dietary protein levels. Pigs fed YE supplemented diets showed significantly (p<0.05) higher amino acid digestibility. Also, high CP level diets showed a higher amino acid digestibility than low CP diets (p<0.05). DM and N excretion did not show any significant differences among treatments, there was a slightly lower excretion with increase in dietary protein level. Supplementation with YE significantly decreased the DM and N excretion. Interaction (YE$\times$protein) was found in P excretion. Pigs fed a medium protein diet without YE showed the lowest P excretion during the growing period. The NH3-N content in the feces tended to be increased by the increased dietary protein levels and with YE supplementation. During the whole experimental period, the cost for YE supplementation was similar to value of the improvements of performance obtained. The cost of feeding high level protein was significantly higher than that of medium level protein by 10% and low level protein by 9% (p<0.05). It could be concluded that the effects of dietary protein level and yucca extract on growth performance, nutrient digestibility and excretion might play a role to some extent in growing pigs from the aspect of pollution control.

  • This study was objectively performed to identify dietitians' job in the elderly health-care facilities, to assess facilities and dietitian's demographic characteristics, and to determine performance and importance of dietitian's job including the demand of therapeutic diet development. Survey was conducted by mail and samples were the dietitians working in 376 facilities which capacity is over 50 members from nationwide 583 the elderly health-care facilities. Returned questionnaire was 102 and used for statistic analysis. The distributions of the elderly health-care facilities showed 39 the elderly nursing facilities(38.2%), 32 skilled nursing facilities (32.4%), 13 geriatrics hospital facilities(12.7%) and 9 the elderly cost nursing facilities(8.8%). 60.0 percent of the samples showed its menu price as 1,000 to 1,500 won. A cycle-menu program was in-use at the 79.0% facilities, but only 7.1% facilities have been introduced a selected menu system. 92.9% facilities employed only one dietitian. In the demographic characteristics of dietitian only 14.7% dietitian had a clinical dietitian license and 51.5% of respondents answered at least 1 to 3 months internship program is needed. Job activities of the dietitian in the elderly health-care foodservice were identified as 45 activities with 9 dimensions. Job performance score evaluated dietitian oneself was 4.71 of 7 points. The average importance score that the dietitian evaluated their own job was 5.66 points of 7. The job activities shown higher importance but lower performance were therapeutic diet development for in-patients, menu development suitable for taste of the elderly, and leadership. Job performance score by characteristics of dietitian and their elderly health-care facilities was significantly associated with experience of dietitian in elderly health-care (F=4.480, p<0.05), education of dietitian(F=2.659, p<0.01), number of dietitian(F=2.245, p<0.05), and number of employee in foodservice(F=2.607, p<0.05). Most common diseases of the aged was proved as hypertension(81.7%), diabetes mellitus(71.4%), and dementia(65.0%). The therapeutic diets frequently provided were diabetes mellitus diet, dysphagia diet, low sodium diet, high fiber diet, and high protein diet, in order. For those reasons, dietitian in the elderly health care emphasized that the information about therapeutic diet development such as diabetes mellitus diet, dysphagia diet, low sodium diet and hypertension diet must be continuously developed and provided. The result from this study can be applicable to enlarge and enrich job activities of dietitian in elderly health-care foodservice.

  • Over 40 per cent Indian population needs to be attended for nutritional improvement. Traditional nutritious food resources though abundantly available but presently less used, if incorporated in the diets, can yield low-cost nutritionally balanced diets. The linear programming (LP)model was used for optimization of food resources to satisfy protein -energy requirements of hard working rural poor. Soybean-a highly nutritious food legume-available at reasonably low price was included along with chick -pea and pigeon -pea for comparison .The three cereals predominantly used in Indian diets -rice, wheat and sorghum -and three typical leafy vegetables namely, spinach , drumstick leaves and rajagira (Amaranths paniculantus) leaves were used for optimization . The contribution of food legume was restricted to supply only 50 per cent of daily protein requirement for maximum protein value. The quantities of other food stuffs namely , milk , sugar , tubers etc. were restricted to nati nal per capita availability. the nutrition satisfaction levels in per cent RDA by the model are 149-250 for protein , 51-106 for fat, 134-362 for iron an d143-1158 for Vitamin-A. Quantities of food legumes, cereals and leafy vegetables ranged from 289-601, 3000-3700 and 360-1200 g/day respectively for a reference family of five hard working rural poor. Daily food resources cost ranged from US$ 0.6 to 1.0 for the family. Amongst food legumes, soybean based diet combinations provide maximum nutritional benefits at minimum cost indicating its suitability for wider adoption by hard working poor.

  • This study was conducted to develop a pasture feeding program for reducing the Hanwoo feeding cost. Italian ryegrass (IRG) is a major plant which is abundantly produced in the southern area of South Korea. Locally produced Italian ryegrass has a 30 - 50% reduced pasture cost compared to imported pasture grasses. We hypothesized that Italian ryegrass feed could reduce the feeding cost but not change the physiological characteristics of the Hanwoo steers in the feedlot. Four treatments (Control, short fed IRG silage, long fed IRG silage, and IRG hay) in a completely random design were used to feed 27 Hanwoo steers. Three or four steers were fed in the same pen, and 8 pens were used for the treatments. Blood was drawn from each steer on the first week of every month from 11 to 30 months. Overall, the average daily gain and feed efficiency were not different among the treatments (p < 0.05) except for the final fattening diets (p < 0.05). The long fed IRG silage group had a low ADG compared to the other groups (p < 0.05). The serum non-esterified fatty acid and glucose concentrations were reduced during the fattening periods (p < 0.05); however, the serum albumin, total proteins, triglycerides, and phosphorus were increased during the fattening periods (p < 0.05). The carcass weight, longissimus muscle area and back-fat thickness were low in the long fed IRG silage group (p < 0.05). The IRG diet induced saturated fatty acids in the longissimus dorsi (p < 0.05). These results show that the IRG diet increased the serum triglycerides but reduced the glucose level at the final fattening diet and decreased the meat yield score in Hanwoo steers.

  • 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.

  • An abandoned mandarin orange orchard in southwestern Japan was set-stocked by Japanese Black cows at two stocking rates (1.0 and 2.0 animals/ha), and vegetation dynamics and diet selection by cattle were monitored for two years, in an effort to obtain information on effective use of abandoned agricultural fields for low-cost animal production and environmental conservation. Two dominant species at the commencement of grazing, kudzu (Pueraria lobata Ohwi) and tall goldenrod (Solidago altissima L.), showed different responses to grazing during the two years; the composition of kudzu decreased, contrasting with that of tall goldenrod which increased at both stocking rates. This was caused by high preference for kudzu and avoidance or low preference for tall goldenrod by cattle. Retrogression of vegetation due to cattle disturbances occurred at both stocking rates, with the high stocking rate leading to a lower degree of succession than the low stocking rate. It was shown that cattle grazing, particularly at a high stocking rate, was effective in the management of vegetation of an abandoned orchard.

  • A feeding trial was conducted to evaluate the effects of crude protein concentration (44% vs 48%) and extrusion processing of soybean meal (SBM) on the performance of weanling and growing pigs. One hundred and ninety two (96 pigs of each sex) 3 way crossed (Landrace ${\times}$ Hampshire ${\times}$ Duroc) weaned pigs were allotted to 12 pens each of 16 pigs (8 pigs of each sex). Three pens were assigned to each of the 4 treatment; $T_1$; 44% SBM diet, $T_2$; extruded 44% SBM diet, $T_3$; 48% SBM diet and $T_4$; extruded 48% SBM diet. The 44% SBM diet was formulated to have 18% CP for the starter phase (5-10 wk of age) and 15% CP for the grower phase (10-15 wk of age). The other treatments used equivalent amount of each SBM, replacing the 44% SBM. Chemical assay showed that extrusion processing generally decreased amino acid content especially total lysine and available lysine. Extrusion increased Hunterlab color +a value and decreased the urease activity index. The body weight gains for the $T_3$ and $T_4$ pigs were significantly(p < 0.05) greater than for those on $T_1$ and $T_2$ for the starter phase, but not the grower phase. Extrusion processing did not improve weight gain. Feed intake for the overall period was significantly(p < 0.05) different among treatments. The feed conversion ratios were not significantly different among treatments. An economic analysis showed that the high protein (48%) SBM diet was more cost effective than the low protein(44%) SBM diet, for the starter phase.

  • The purpose of this study was to : (a) examine diabetic patients' sensory evaluation and food preferences, (b) analyze the portion sizes & plate wastes, (c) investigate the factors affecting plate wastes, and (d) determine the nutritional & mometary values of the plate wastes. A questionnaire for determining food preference and sensory evaluation was developed. Thirty-three diabetic patients who were hospitalized in Sanggye Paik hospital in Seoul were studied. Serving sizes and plate wastes were weighed by using an electric scale, and the CAN-Pro program was used to evaluate the nutritional value or the food consumed. The data were analyzed using the SAS package program for descriptive analysis, t-test, ANOVA, and the Pearson correlation. Using a five-point Likeu-type scale, the temperature s[ore ranged from 3.1 to 3.3 (1 : very poor, 5 : excellent), the preference store was 3.0-3.2 (1 : very dislike, 5:very like), the taste score was 2.9-3.2 (1 : very poor, 5 : excellent), and the amount of food served score was 2.8-3.0 (1 : too little, 5 : too much). Serving sizes were considered insufficient by patients because most of the DM diet was low in calories. Average plate waste for the DM diet was 26.2% of the total served, by weight, and was lower than that for patients consuming a normal diet, which was 30.3%, found in previous research. Those subjects who had been previously hospitalized and who wished to participate in a campaign for food waste reduction produced less plate waste than other groups (p<.05). Plate wastes of the DM diet were negatively correlated with taste, temperature, and preference, and were positively correlated with the amount served: however, these results were not statistically significant. It was found that diabetic patients consumed adequate levels of energy, protein, Ca, Fe, Vitamin B$_1$, Vitamin B$_2$, and niacin, but inadequate levels of Phosphorus, Vitamin A and Vitamin C. The plate wastes were calculated to be 26.2% of the total cost (₩ 3,489), which is ₩9l5. This represents a significant wastage of resources from the hospital. The results of this study could assist foodservice managers in both controlling food wastage, and improving the quality of hospital food services.

  • Timing of weaning is later in Korean rural and lower urban classes compared with middle and upper classes. Weaning after the international standard of six months of age has adverse effects on the growth rate of children. This occurs because supplementary foods are not provided for the child during the weaning period; rather, the infant goes directly from nursing(or bottle feeding) to the cereals and solid foods of the adult diet. Consequently, all nutrient and calorie intake, with the exception of thiamin, in Korean rural children had not yet attained the Recommended Dietary Allowance (RDA). This situation bas created an urgent need for easy to prepare, low priced. highly nutritious supplementary foods. The research team of Yonsei University developed 3 formulas prepared from rice, soybeans, sesame, dry skim milk and fish which are all plentiful and inexpensive items in Korea. A proximate analysis and amino acid determination were performed on three formula. These formulas were prepared and used as exprimental diet for an animal assay. In the animal assay, growth rate, PER evaluated and biochemical analyses were also carried out. A safety storage assay and the cost evaluation were also conducted.
