  • 본 시험은 한방약제 추출물 급여가 과밀사육 환경에서의 육계 (Ross broiler)의 생산성 및 면역세포 중식에 미치는 영향을 조사하기 위하여 실시하였다. 육계 수컷 240수를 저밀도 사육구와 고밀도 사육구로 나누어 각각 대조구와 처리구를 두었으며 저밀도 사육구는 pen 당 10수씩 고밀도 사육구는 pen당 30 수씩 임의 배치하였다. 저밀도와 고밀도의 대조구 사료에 한방약제 추출물 0.23%(AP 0.2%+ DFP 0.03%)를 첨가 급여였다. 사육밀도에 따른 평균 사료섭취량은 저밀도 사육구에 비하여 고밀도 사육구에서 유의하게 낮게 나타났으며(p<0.05), 한방약제 추출물 첨가에 따른 영향은 없었다. 사육밀도에 따른 평균 체중은 고밀도 사육구에서 저밀도 사육구보다 유의하게 낮게 나타났으나(p<0.05), 저밀도와 고밀도 사육구 모두에서 한방약제 첨가 처리구가 대조구에 비하여 통계적 유의차는 없었으나 일당증체량은 개선되는 경향을 나타내었다. 과밀사육에 의한 증체량 감소 및 사료섭취량 감소 현상은 생육 중기에 주로 나타난 결과 이며 후기에는 이러한 환경에 적응하여 회복되는 것으로 나타났다. 사료요구율은 한방약제 첨가 처리구가 고밀도 사육구 및 저밀도 사육구에서 유의한 차이는 없었으나 모두 개선되는 경향을 보여 주었다. 면역세포증식은 비장세포 종식도, LPS로 자극시킨 B세포 증식도와 ConA로 자극시킨 T세포 증식도 모두에서 한방약제 추출물 처리구에서 유의한 차이를 보이며 높은 증식도를 나타내었다(p<0.05). 결과적으로 고밀도환경하에서 한방약제 추출물 급여에 따라 육계의 면역력이 증가한 것으로 판단되며, 궁극적으로 육계의 질병예방 및 일부 생산성 향상에도 긍정적인 영향을 미칠 수 있을 것으로 판단된다.

  • This survey was carried out to study the difference of nutrient intake, food behavior and health condition according to food intake diversity in the elderly(age 65 year over and 74 year under) in a local city. A diet survey with one day 24-recall method was used for 216 subjects(65 male & 151 female). Based on a food intake diversity examination, including an evaluation of KDDS(Korean's Dietary Diversity Score ; counts the number of food groups consumed daily from total five food groups(cereal, meat, vegetable, dairy, and oil groups)), Meal Balance(apply the KDDS at breakfast, lunch and dinner), and DVS(Dietary Variety Score ; total number of foods consumed), subjects were clustered according to food intake diversity. Food intake diversity patterns of male and female clusters were classified each into threes(Male-low group(24.6%), middle group(33.8%), and high group(41.5%)/Female low group(41.7%) middle group(37.1%), and high group(21.2%). The averages of KDDS, Meal Balance and DVS were 3.0, 7.5, 14.8 in the male middle group, and 4.5, 10.2, 25.7 in the male high group, 2.7, 6.3, 14.3 in the female low group, 4.0, 8.6, 18.0 in the female middle group, and 4.5, 10.5, 25.7 in the female high group respectively. The average dairy intake of nutrients below the RDA were energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$and niacin in the male low group, energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$in the male middle group and energy, Ca, Vitamin B$_2$in the male high group but a little. Also the female low group had intakes of all nutrients except Vitamin C, the middle group had intakes of energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$, and the female high group had intakes of energy, Ca, Vitamin A below the RDA respectively. Food intake diversity increasing, nutrient intake, food behavior and health condition proved to be good. This study explored the usefulness of cluster analysis in identifying food intake diversity of three groups of the elderly in relation to their nutrient intake, food behavior and health conditions.

  • The gut microbiome influences the health and well-being of dogs. However, little is known about the impact of breed on the fecal microbiome composition in dogs. Therefore, we aimed to investigate the differences in the fecal microbiome in three breeds of dog fed and housed under the same conditions, namely eight Maltese (8.0 ± 0.1 years), eight Miniature Schnauzer (8.0 ± 0.0 years), and nine Poodle dogs (8.0 ± 0.0 years). Fresh fecal samples were collected from the dogs and used to extract metagenomic DNA. The composition of the fecal microbiome was evaluated by 16S rRNA gene amplicon sequencing on the MiSeq platform. A total of 840,501 sequences were obtained from the 25 fecal samples and classified as Firmicutes (32.3-97.3% of the total sequences), Bacteroidetes (0.1-62.6%), Actinobacteria (0.2-14.7%), Fusobacteria (0.0-5.7%), and Proteobacteria (0.0-5.1%). The relative abundance of Firmicutes was significantly lower in the Maltese dog breed than that in the other two breeds, while that of Fusobacteria was significantly higher in the Maltese than in the Miniature Schnauzer breed. At the genus level, the relative abundance of Streptococcus, Fusobacterium, Turicibacter, Succinivibrio, and Anaerobiospirillum differed significantly among the three dog breeds. These genera had no correlation with age, diet, sex, body weight, vaccination history, or parasite protection history. Within a breed, some of these genera had a correlation with at least one blood chemistry value. This study indicates that the composition of the fecal microbiome in dogs is affected by breed.

  • Effects of different levels of molasses in a concentrate supplement on milk yield of cows grazing Setaria grass pastures were investigated. Thirty Friesian cows, 6-7 years old with mean pre-experimental body weight of $428{\pm}6.5$ kg, in early stage of lactation were randomly allotted to five dietary treatments in a completely randomized design experiment that lasted for 126 days. Experimental dietary treatments were forage alone and forage/concentrate mixtures with molasses included at 0, 5, 10 or 15% levels designated as $T_1$, $T_2$, $T_3$, $T_4$ and $T_5$, respectively. The parameters studied were voluntary dry matter (DM) intake, average daily live weight change (LWC), milk yield, body condition score (BCS) and apparent nutrient digestibility coefficients. The DM and energy contents of Setaria grass were low compared to the concentrate diets. Fibre fractions-NDF, ADF, ADL, hemicellulose and cellulose; and gross energy were higher in concentrate mixtures than in the forage. Total DM intake (forage+concentrate mixtures) was significantly higher (p<0.001) in cows on the concentrate mixtures. LWC was not significantly different (p>0.05) between the cows. Average milk yields were significantly different (p<0.05) between cows. Fat corrected milk (FCM) was similar among cows in the treatments. BCS was better (p<0.001) in cows on concentrate mixtures. Digestibilities of DM, CP, NDF, ADF, ADL, OM, and energy were significantly higher (p<0.001) in cows on $T_2$, $T_3$, $T_4$ and $T_5$ than in those on $T_1$. There were no significant differences in the digestibility of DM, CP, NDF, ADF and ADL (p>0.001) in cows on concentrate mixtures. This study therefore demonstrated that lactating dairy cows in Fiji need a level of readily fermented energy source such as molasses in their diets; however, a level above 10% is not nutritionally suitable for lactating dairy cows. Based on data on production parameters-milk yield, fat corrected milk, body condition score and apparent nutrient digestibility coefficients-molasses levels that range between 5-10% are recommended, however, 10% is the best and therefore recommended for inclusion in the concentrate mixture of lactating dairy cows on a basal diet of Setaria sphacelata in Fiji.

  • This article concerned with the nutritional status and the taste of the lunch box of 311 middle school girls in Kwangju City from May 18 to June 12 in 1987. The purpose of this research was making materials to show direction of the education about nutrition by checking relationships among the nutritional status for the lunch box, the taste of food and the environmental factors. The results observed in the study were as follows: 1. The intake of nutrition from the lunch box and the ratio between the recommended dietary allowance and the contained nutrients in the lunch box as follows. Calorie(603 Kcal, 78.6%), protein (21.7g, 93.1%) Animal protein (10.3g, 132.1%) calcium (151.7 g, 56.9%) Ferrum 93.1 mg, 51.7%), Vitamin a (129.3 RE, 55.4%) Vitamin B1 (0.29 mg, 72.5%), Vitamin B (0.26 mg, 55.3%) Niacin (4.7 mg, 94.0%), Vitamin C 913.2 mg, 79.0%). Except animal protein, all the recommended dietary allowance. 2. According to the intake of calorie, the ratio of taken carbohydrate, protein and fat was 77.7 : 15.5 : 6.8. The intake of protein was desirable but most of calorie depended on carbohydrate. Among the total intake of protein, the ratio of animal protein was 47.5%, which was a high rate. 3. Most of calorie (75%), was taken from staples, protein (41.5%), vitamin B1 (48.3%) were taken at the same rate from staples and side dishes. Most of fat, calcium, ferrum, vitamin A, vitamin B, and vitamin C, was taken from side dishes. 4. In taking among the five basic food groups, proportion of the grain fourth food group was the highest, light color vegetable the third food groups, proportion of the grain fourth food group was the highest, light color vegetable the third food group was second, and Calcium food the second food group was the lowest. 5. As the staples, students liked tchajangmyon, mandu and ttokkuk as written order. They disliked Kongbap and Patpap. As the side dishes for the lunch box, they liked kimchi, ham, sausage, cuttlefish, dried slices of filefish, eggs and green seaweed as written order. As a side dishes they liked Laver, Cucumber, Squid, lettuce, Potatoes. They disliked pork fat, cow's intestines, cow's liver, Crussian carp, pickled fish. The favorite snack was fruits, ice cream, hamburger, Chocolate and milk. 6. In taking condition of the principal food, rice rate (65.6%) was the most, and mixed food was 5 or 10%. 7. Favorite cooking was frying, roasting and kimch. But disagreeable cooking was pickling. 8. Favorite food was what was pungent but disagreeable food was what was salty. 9. the higher parents educational background was, the higher their income was. Also the more various the information about the nutrition was, the better the intake of nutrition was. 10. The preference tendency influenced in choosing the side dish of the Lunch box. The higher the preference tendency of the girl students became, the better their nutrition condition became.

  • Aging rate of rural area in our country is relatively high compared to that of the urban area. Thus, the introduction of meal service for the elderly residing in the rural area is necessary for their better living quality. Food habit, health and the nutritive intake conditions during the busy farming season were surveyed and comparative analysis of dietary intake for the introduction of meal service in pavilion of the elderly living in Chungnam, Kangwon, Jeonnam and Kyungbuk was performed for basic reference data of meal service introduction to the pavilion of the elderly in rural area. In general subject, the male elderly had a significant difference in marital state and showed that 79.4% was married and 20% was separated by death(P<0.05). In allowance, there were no significant difference but most of them lived with less then three hundred thousand won and especially, female lived with less then one hundred thousand won. In health state, the female elderly showed significant difference on difficulty with every day activity but with small trouble although they had to prepare their own meal(P<0.05). The condition dental health conditions of the female elderly had a significant difference showing bad conditions in following order; Kangwon(48%)>Chungnam(38.1%)>Kyungbuk(22.9%)>Jeonnam(22.5%)(p<0.05). The female elderly showed a significant difference in usage of denture and number of the female elderly without using the denture were very high(p<0.05). In nutrition intake condition, amount of sodium was very high but intakes of fiber and calcium were relatively 1ow(P<0.05). Meal service introduction in the pavilion of the elderly is suggested for the improvement of the life quality of the elderly in rural area. When developing the menu for them, conditions such as shortage of the fiber and calcium in diets, the dental conditions should be considered.

  • A feeding trial was conducted in tilapia to determine the growth performance, nutrient digestibility, digestive enzymes, and postprandial blood metabolites in response to different dietary amylose-amylopectin ratios. Five isonitrogenous and isolipidic diets containing an equal starch level with different amylose-amylopectin ratios of 0.11 (diet 1), 0.24 (diet 2), 0.47 (diet 3), 0.76 (diet 4) and 0.98 (diet 5) were formulated using high-amylose corn starch (as the amylose source) and waxy rice (as the amylopectin source). Each diet was hand-fed to six tanks of 15 fish each, three times a day over a 6-wk period. After the growth trial, a postprandial blood metabolic test was carried out. Fish fed diet 2 exhibited the highest percent weight gain and feed efficiency and protein efficiency ratio, whereas fish fed with diet 5 showed the lowest growth and feed utilization among treatments. The digestibility for starch in fish fed diet 1 and 2 was higher than those in fish fed with other diets (p<0.05). The highest activities for protease, lipase and amylase were found in fish fed the diet 2, diet 1, and diet 1 respectively among dietary treatments, while the lowest values for these indexes were observed in fish fed the diet 3, diet 5 and diet 4, respectively. The liver glycogen concentrations in fish fed diets 4 and 5 were found higher than in fish fed other diets (p<0.05). The feeding rate, hepatosomatic index, condition factor, and plasma parmeters (glucose, triglyceride, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol) did not differ across treatments. In terms of postprandial blood responses, peak blood glucose and triglycerides were lower after 3 or 6 h in the fish fed with diets 3-5 than in the fish fed diet 1, but delayed peak blood total amino acid time was observed in fish fed with the diets 1 or 2. The lowest peak values for each of the three blood metabolites were observed in fish fed diet 5. The results indicate that high-dietary amylose-amylopectin ratio could compromise growth, but help in reducing the blood glucose stress on fish caused by postprandial starch load.

  • To investigate the comparison of dietary status and health behaviors according to obesity, 239 male workers were selected and classified as normal (18.5-22.9 27.2%), overweight (23-24.9, 37.7%), and obese (25-29.9, 35.2%) by body mass index ($kg/m^2$). The SAS (ver. 9.2) program was used and verified by the chi-square and f-value methods. Drinking frequency(2-3 times a week) was higher in normal males(45.3%), but not as high as in obese males (48.1%) (p<0.001). Smoking frequency and amount were the highest in overweight males, but not-quit-smoking was high in obese males(51.9%) (p<0.001). Exercise time was longer in normal males(108 minutes) than other groups(69 overweight males, and 82 obese males (p<0.01). Obese groups(73.8%) slept well (p<0.001), but overweight males(44.4%) showed less than 6 hours of sleep (p<0.01). Meal frequency differed by group(two meals a day 67.7% in normal males (p<0.001), no-snack 65.5% in obese males(p<0.001). The frequency of eating-out was once a day in normal males (38.5%), differed in the eating-out time (lunch(45.8%) in normal males, dinner in overweight males(52.1%) and obese males(59.5%) (p<0.01). Korean food (49.3%) was selected, but noodle differed by group(10.2% normal 21.5% obese (p<0.01). Self-perception of body differed from the body's actual condition(p<0.001). For weight control, exercise(56.4%) was practiced more than diet(18.6%). Nutrition knowledge was poor (correct answer rate was 36.7% in normal males, 41.7% in overweight males, and 46.7% in obese males). For eating attitudes, obese males answered more in "flexible to change eating habits", "supplemented when poor eating"(p<0.001), normal responded in "impact on nutrition to health", "try new food for health"(p<0.01). From these results, it is evident that male workers, especially overweight ones, must work to learn more about health and nutrition so as to combat chronic diseases.

  • BACKGROUND/OBJECTIVES: A growing body of research has indicated that night eating could be associated with poor diet quality and negative health outcomes. This study examined the nutritional aspects of night eating, its related factors, and the association between night eating and body weight among Korean adolescents. SUBJECTS/METHODS: This study analysed the data from a one day 24-hour dietary recall as well as a demographic survey of 1,738 Korean adolescents aged 12 to 18-years-old obtained from the 2010-2012 Korea National Health and Nutrition Examination Survey. 'Night eating' was defined as consuming 25% or more of one's daily energy intake between 21:00 and 06:00. Subjects complying with the preceding condition were classified as 'night eaters', whereas the rest were considered 'non-night eaters'. Logistic regression analysis examined factors related to night eating. Multiple linear regression analyses were used to examine the relationship between night eating and BMI z-scores, whereas multinomial logistic regression analysis was used to examine the relationship between night eating and weight status. RESULTS: About 21% of Korean adolescents appeared to be night eaters. Night eaters showed increased breakfast skipping (P = 0.001), higher energy intake from snacks (P < 0.001), greater proportion of energy intake from fat (P = 0.029), and lower Dietary Diversity Scores (P = 0.008) than non-night eaters. Male adolescents presented 1.9 times higher odds of being night eaters than females. Adolescents whose both parents were night eaters were 4.4 times as likely to be night eaters as those whose neither parents were. Female adolescents showed a significant relationship between night eating and BMI z-scores (${\beta}=0.28$, P = 0.004). However, night eating did not increase odds of being overweight or obese in adolescents. CONCLUSIONS: Night eating in Korean adolescents was related to undesirable dietary behaviours and low diet quality in general as well as higher BMI z-scores in females. Male gender and parental night eating appeared to be the factors that significantly increased odds of night eating. These results suggest that night eating should be considered when designing nutrition education or intervention programs targeting adolescents.
