  • The objective of this study was to examine the effects of concentrates containing different levels of a vitamin-trace elements premix on milk yield and composition of dairy cows. The trial, which lasted 14 weeks, was conducted from January to March and used 45 multiparous Brown cows in the early phase of lactation. Cows (n = 15 per treatment) were randomly allocated to three dietary treatments: the first group (control, C-0) was fed pelleted concentrate containing background vitamins and trace elements that supplied 1.0 times cows' daily requirements; the second group were fed the same concentrate, but containing 2.5 g/kg of vitamin and trace mineral premix per kg of concentrate (C-2.5); the third group were fed the same concentrate, but containing 5 g/kg of vitamin and trace mineral premix per kg of concentrate (C-5). The daily ration included ad libitum chopped oat hay, and the cows also had 8 h/d grazing on a ryegrass (Lolium multiflorum) pasture. During the performance trial, cow milk yield was daily recorded and individual milk samples were analysed for milk composition and to determine milk renneting properties. Cows fed the intermediate premix level (C-2.5) in diet showed the highest fat-corrected milk production (p<0.05) compared to other groups. None of the milk quality parameters studied were influenced by dietary treatment, except for milk rheological parameters (rennet clotting time and curd firmness) that were positively improved in cows fed the C-2.5 diet (p<0.05). The findings from this study show that intermediate level of vitamin-trace elements premix in concentrate can be advantageously used in grazing dairy cows without negative effects on yield and quality of milk produced.

  • In order to investigate the relationship between intake conditions of health food and health-related factors by residence and sex in Tong-Young area, a survey was carried out from 1,303 adults. Health foods were classified 3 groups including vitamin and mineral supplements, toner foods and manufactured health food supplements. Health-related factors were stress, fatigue, smoking and drinking. The $29.5\%$ of the subjects had taken some health food for health. Especially the male took more toner foods habitually than the female did. In take of vitamin and mineral supplements by residence, there was a significant difference $(p\leq0.01)$ as follows. The subjects in island $(20.0\%)$ who took vitamin/mineral supplements were about two times as compared with the subjects in Dong $(10.8\%)$, or Eub-Myeon $(10.0\%)$. The subjects taking supplementary food replied over fair $(82.8\%)$, the subjects taking toner food replied over fair (90.3$\%$) scored higher than who replied bad or very bad in self-perceived health status. Therefore, the better the subjects felt self-perceived health status, the more they took health foods for health themselves. In self-perceived stress status, the subjects who replied a little $(50.0\%,\;45.3\%)$ or little $(19.9\%,\;26.4\%)$, took vitamin and mineral supplements or manufactured health foods a lot. In toner food there was a significant correlation $(p\leq0.05)$ as follows. The less the subjects felt stress, the more they took dietry supplement. No smoker $(12.9\%)$intake rate of vitamin and mineral supplements was higher than smoker $(8.8\%)$. Smokers $(6.5\%)$ intake rate of toner food was higher than no smoker $(4.0\%)$. It was not significant the relationship between intake condition of health food and drinking. The main motivation for taking health food were by self-decision and invitation of friends or neighbors.

  • This work was designed to investigate the performances of broiler breeder hens upon the addition were vitamin and mineral supplements in feeds. Animals were divided into for feed groups such as control, T$_1$,T$_2$and T$_3$, and each treatment has four replications. All broiler breeder hens were housed individually, and were fed with identical iso-metaboilic energy and iso-protein, except for vitamins and minerals. Different sources and levels of vitamins and minerals were added to the basic feeds according to the treatments. At the end of the experiments, general laying rate(hen days), average egg weight, hatching egg laying rate(Hen day) every day. Hatching egg weight, sterility, embryo mortality, hatching rate and chick weight were examined. Although, early laying rate in all treatment groups were reduced during cold term management, general egg laying rate was increased only T$_3$group which was contanining vitamin C. However, similar results were obtained in the rates of general and hatching egg laying. General egg laying rate were somewhat higher of Control, T$_2$and T$_3$ groups than that of T$_1$group. In addition, the laying rates of general and hatching eggs slightly improved in the T$_3$group rather than those of Control group. Egg weight was reduced with the increasing of laying rate, showing the highest in the T$_3$group. The laying rate showed significantly lower value than those of any other groups. Egg weight was about 65g in T$_3$group. The results of hatching performance for production ability of Broiler breeder hens were fed experimental diet, although the rates of non-hatched and hatched eggs increased in order of Control, T$_1$T$_2$and T$_3$groups. However, the rate of embryo mortality was declined in order Control, T$_1$T$_2$and T$_3$groups.

  • An experiment was conducted at the experimental duck farm of Cantho University to determine the effects of feeding duckweed (Lemna minor) that completely replaced commercial protein supplements in diets for crossbred meat ducks. The experiment included five treatments, with four replicates and ten crossbred ducks per replicate (pen). The five diets were based on broken rice offered ad libitum, supplemented with either 27 (control, SB100), 19 (SB70), 15 (SB55), 12 (SB40) or zero (SB0) g/day of ground, roasted soya beans, with fresh duckweed supplied ad libitum, except for the control (SB0) treatment. A vitamin / mineral premix and salt were included in the control (SB100) diet, but not in the diets with duckweed. These diets were fed to growing crossbred meat ducks (Czechoslovak Cherry Valley hybrids) from 28 to 63 days of age, when two birds (one male and one female) per pen were slaughtered for carcass evaluation. Total daily intakes were 95, 108, 108, 105 and 107 g of dry matter (DM) (p<0.001) and daily live weight gains 26.1, 29.1, 28.3, 27.1 and 27.6 g (p<0.001) for the SB100, SB70, SB55, SB40 and SB0 diets, respectively. Corresponding feed conversion ratios (FCR, dry matter basis) were 3.63, 3.71, 3.82, 3.89 and 3.88 kg feed/kg gain, respectively. There were no significant differences in carcass yields, chest and thigh muscle weights, and internal organ weights between the ducks fed the control diet and those fed duckweed diets. Fresh duckweed can completely replace roasted soya beans and a vitamin-mineral premix in broken rice based diets for growing crossbred ducks without reduction in growth performance or carcass traits. If the duckweed is grown on farm, and managed and harvested by household labour, the saving over purchased protein supplements is up to 48%.

  • Gelatin soft capsules, manufactured by the press through package(PTP) process, are widely used in the production of multivitamin dietary supplements and other health functional foods. Gelatin capsules can prevent light and air from having a direct contact with the contents in the capsule, and the nutrients inside the capsules are preserved without any loss. In the present study, on the basis of the results on the safety of gelatin capsules. The parameters investigated included degradation of the capsules before their shelf life, capsule deformation, and changes in specific nutrients. Moisture and heat in the production and storage environments of the capsules caused the gelatin to swell and attach some of the inorganic salts in the vitamin contents. Nutritional component analysis showed that B1, B5, B9, and B12 contents were decreased, while mineral elemental analysis shown calcium, chloride, and zinc compound were found to be infused into the gelatin of the capsule shell.

  • The issue of health and nutritional wellbeing becomes one of the utmost concerns for the welfare of the elderly in a society of increased aging populations. This study was conducted to assess nutritional state and to identify possible dietary factors that might influence health and nutritional state of the free living elderly women. Two hundred sixty two elderly women, aged 60-90 who are actively participating in a continuing education program for the elderly in Seoul area, were interviewed using a dietary habit questionnaire and a 24-hour recall. Anthropometric measurements such as heights, weights, body mass index, and tricep skinfolds and dental status were significantly different between the two age groups, <75 and ${\geq}$ 75 years of age. Sixty eight percent of the subjects were using nutritional supplements regularly, in the descending order of vitamin-mineral supplements(40%), botanicals(27.6%), tonic drinks(16%), and health foods(13.2%). For hot beverages, our study subjects drank coffee (33.6%) and green tea (17.9%) frequently, followed by doongulae, job's tears, citron and kyulmyung tea. With regard to micronutrients, vitamin C intake was found to be lower in the group aged over 75 compared to that below 75 (p<0.05). Calcium intake was significantly higher among the elderly with good dental status followed by the groups with gingivitis, denture, and missed teeth with poor chewing abilities (p<0.05). The amount of personal spending money was found to be a significant contributing factor (p<0.05) to the energy and nutrient intake in an individual. The results of the present study can be applied to the identification of the possible factors that might intervene the aging process, to the planning of the nutrition education program, and to the development of health food products for the promotion of health and nutrition of the elderly women.

  • Various types of functional foods for health (FFH) are popularly used among adolescents. We surveyed 858 students, $15.0 \pm$ 1.6 (14-18) years of age, attending general junior or senior high schools in Korea for FFH use and significant variables for their FFH use including demographic characteristics, food consumption frequency and nutritional beliefs. The use prevalence of FFH was $47.8\%$, and among all types of FFH, nutritional supplements were taken most frequently, followed by red ginseng products > enzyme containing products > plant extract-fermented products. FFH use was higher in older aged-group, subjects lived in small or middle city, and those from families with a high socioeconomic status in comparison to each corresponding group. Health concern on offsprings by parents and usage ratio of FFH by family was higher in users than in nonusers of FFH. Total score of dietary assessment was higher in users than in nonusers of FFH, and users had a more positive view concerning the potential health benefit of FFH than did nonusers. Most users of FFH took FFH when they were healthy ($50.7\%$) , and they did not feel special effects through the FFH use ($57.1\%$) . Most users of FFH got the information on FFH through family and relatives ($61.5\%$) , and most of them purchased FFH at pharmacy or oriental medicine clinics ($55.1\%$) . FFH users preferred vitamin C-and Ca-supplements most among the vitamin mineral supplements belonged to FFH. Given the widespread use of FFH by adolescents, the reasonable use of these products for the contribution to their overall health and well-being is a subject that is emphasized in nutrition education for them.

  • We surveyed 848 university students, $21.4{\pm}2.5$ years of age, attending university in Seoul, Kongju, Chongyang-Gun in the Chungnam province of Korea, for their use of health functional foods (HFF) and for significant variables in this use, namely demographic characteristics, health related variables, dietary variables and nutritional beliefs. The prevalence of the use of HFF was 33.6%. Among all types of HFF, nutritional supplements were taken most frequently, followed by (in order) red ginseng products, apricot extract products and ginseng products. HFF use was higher in females (p<.05), in subjects living in a dormitory (p<.05) and those from families with a relative high socioeconomic status (p<.001). Self-health concern (p<.05) and usage ratio of HFF by family (p<.001) was higher in users than in nonusers of HFF. The total score of dietary assessment was higher in users than in nonusers of HFF (p<.001), and users had a more positive point of view concerning the potential health benefits of HFF than did nonusers (p<.001). Most users took HFF when they were healthy (37.2%) or when they were sick (27.4%). They did not feel special effects through the HFF use (49.8%). Most users got the information about the specifics of HFF from family and/or relatives (55.8%). Most of users confirmed nutrition facts when they purchased the HFF (70.9%), but a considerable number of users could not understand these nutrition facts (48.1%). Users preferred vitamin C- and Ca-supplements most among vitamin mineral supplements belonged to HFF. These results show that the use of HFF is common among university students. As well, the use of HFF by students is affected by various variables. Supplementary nutritional education should be undertaken among university students, in order to give them a reasonable guideline for the use of HFF, based upon influencing factors and usage behaviors that we learned from this survey.

  • Cigarette smoking has a negative effect for nutrient intakes and nutritional status of antioxidant nutrients including vitamin C. This study has been performed to compare the dietary nutrient intakes, serum vitamin C concentration and serum cotinine concentration of smoking teenage girls(n=104) with those of non-smoking teenage girls(n=791). The subjects were 895 high school girls(15-19 years of age) living in a rural community in Korea. Of the subjects, 11.6% stated that they were currently smoking. The frequency of taking alcohol, soda and coffee was higher in smokers than in non-smokers, respectively. The usage rate of vitamin/mineral supplements was higher in smokers than in non-smokers. The smokers tended to skip breakfast and lunch and to take snack more often than did the non-smokers. The dietary intakes of calorie, protein, vitamin A, vitamin B, vitamin C, calcium and iron were lower in smokers than in non-smokers. Daily mean intakes of these nutrients were less than the 2/3 of the Korean RDAs in smokers while these intakes were similar to or more than the RDAs in non-smokers. The ratio of under weight or lean tended to be higher in smokers. Serum vitamin C concentration was lower in smokers than in non-smokers. These findings show that smokers have unsound eating habits and poor nutirtional status. In particular, nutritional status of vitamin C is significantly poor in smokers, and this tendency can be found more notably in heavy smokers. Therefore, oxidative stress may be present in young teenage girls with short smoking history as evidence by above results. (Korean J Nutrition 34(3) : 338∼347, 2001)

  • The objective of this study was to investigate the effect of maintenance system as well as the effect of Se, Zn, and vitamin E supplementation of ram-lambs on the slaughter value and concentration of mineral elements in the loin muscle of lambs. The experiment was conducted on 72 Polish Merino ram-lambs divided into three groups: group C, indoor with no supplement, 19 lambs; S, indoor with supplement, 23 lambs; G, outdoor with no supplement, 30 lambs. From birth all the lambs were maintained indoor with their dams and then weaned at the age of 8 weeks. The rams from group C and S were placed in individual straw-bedded pens and fattened individually with concentrate mixture offered ad libitum until the age of 16 weeks. The lambs from group G were grazed every day from May to July (2 months). During the fattening period each lamb from the supplemented group S was administered per os 1 mL 0.1% $Na_2SeO_4$ (Se, 0.42 mg), 3 mL 10% $ZnSO_4$ (Zn, 68 mg), and 1 mL premix protect vitamin E (0.1 g ${\alpha}$-tocopherol, 5 mg lysine, 5 mg methionine) daily. A comparison of half carcasses across the groups has shown no difference between the control group and the one with supplements, while the weight of half carcasses in the grazing group was smaller in comparison with groups C and S (p<0.001). The meat content in the pelvic limb showed no differences across all groups under study. The pelvic limb of grazing lambs contained less fat compared to the control and supplemented groups (p<0.001). The concentrations of Se and Zn in the blood plasma of ram-lambs from the supplemented group were significantly higher than for the control and grazing lambs. Inorganic Se and Zn supplementation with vitamin E to the diet of lambs increased Se and Zn levels in loin muscle (p<0.001) to $0.46{\mu}g/g$ and $32.9{\mu}g/g$ in fresh tissue, respectively.
