Among Italian buffalo farmers, it is widely held that administering diets with high energy and protein concentrations is an effective way to increase milk production. In order to assess the validity of this opinion, we verified milk yield and physico-chemical characteristics from buffaloes that, from the $5^{th}$ month of lactation, were fed two total mixed rations (TMRs) which, given the same intake, should have led to satisfaction of protein requirements though with a slight energy deficit (diet A) or excessive amounts of energy and protein (diet B). Estimate of the energy and protein value of the diets and that of the corresponding requirements was carried out both by using two software programs derived from the Cornell Net Carbohydrate and Protein System (1992), and with the method set up by INRA researchers (1988). The results obtained show that the two diets administered did not result in significant changes to the quantity of milk produced. However, with Diet B the protein concentration in the milk was significantly (p<0.01) higher, although this was partly offset by the higher concentration (p<0.05) of non-protein nitrogen (NNP). The Group B buffaloes also showed significantly higher blood urea levels (p<0.01), with concentrations exceeding those considered physiological for lactating buffaloes. Finally, while administering Diet A the Body Condition Score (BCS) was close to 6.5 (Wagner et al., 1988), whereas in buffaloes which used Diet B it sometimes increased by over 0.5 points. As regards which of the two methods compared is more suitable for expressing dietary energy and protein value and corresponding requirements, we feel that due to the high variability in the Italian Mediterranean buffalo's milk production aptitude, it would be premature to express a judgement on methods which rest on a common scientific base and do not differ substantially.

Influences of Japanese green tea powder (GTP) supplementation to commercial diet on laying performance and egg quality were studied by using 60 laying hens. The experimental diet with or without 0.6% GTP was given ad libitum to the birds during the period from 6 to 71 weeks of age. The birds started egg production from 21 wk of age regardless GTP feeding. Body weight, feed intake, egg weight tended to decrease with GTP supplementation, while egg production rate tended to increase. Haugh unit score was significantly increased with GTP, which accompanied with the increased albumen height. These were observed almost throughout the laying period over 50 wk. Gel proportion in thick albumen was decreased as storage time is prolonged, then higher values of the gel proportion were recorded in the eggs from GTP group. Thick albumen of the eggs from GTP-fed layers had more carbohydrate than that from control layers. All these indicate physical stability of thick albumen in the eggs from GTP group. Thiobarbituric acid content of egg yolk tended to remain lower in the eggs from GTP group during 5-10 days of storage at room temperature. Levels of egg yolk cholesterol and yolk lipid were significantly reduced by GTP feeding. There were no significant differences in eggshell weight, shell thickness and shell strength between the two groups. Thyroid gland and liver from hens slaughtered at 71 wk of age did not differ in weight irrespective of GTP feeding. The present results suggest that GTP could modify components of edible part of egg, leading to the characteristics favourable to consumers such as high durability of thick albumen and less cholesterol in yolk, without altering general performance of the layers throughout this year round experiment.
Recent studies have reported that a subset of obese individuals who were metabolically healthy but obese had more favorable clinical outcomes than obese subjects with metabolic disturbances. The purpose of this study was to evaluate the distribution and agreement of obesity subtypes according to body mass index (BMI) and metabolic syndrome (MS). Furthermore, we examined the differences of nutrient intake among the groups. Data was analyzed for 1,095 female subjects older than 40 years using Korean National Health and Nutrition Survey in 2008. The degree of obesity was classified by two methods, using BMI (obese ${\geq}\;25\;kg/m^2$, not obese < $25\;kg/m^2$) and MS (meet ${\geq}\;3$ criteria among 5 index: waist circumference, triglyceride, glucose, HDL-cholesterol and blood pressure). Subjects were divided into 4 groups according to $2{\times}2$ cross table: non-obese without MS, non-obese with MS, obese without MS and obese with MS. Nutrient intakes were compared among 4 groups. The results showed that the proportions of non-obese without MS, non-obese with MS, obese without MS and obese with MS were 47.6%, 13.6%, 16.6%, and 22.2% of total subjects, respectively. The agreement (kappa value) of two methods was 0.354 (fair) in total subjects, 0.365 (fair) in 40-60 year old subjects and 0.304 (fair) in ${\geq}\;61$ year old subjects. In ${\geq}\;61$ years old subjects, intakes of percentage energy from carbohydrate, percentage of energy from fat, calcium, phosphorous, sodium, vitamin A, carotene, thiamine, riboflavin and niacin were significantly different among the groups. In contrast, the subjects of 40-60 years old, no differences in nutrient intakes were observed. In conclusion, there were differences in nutrient intakes among the groups subdivided by obesity and MS, especially in elderly female subjects. Individualized dietary guideline for subtype of obesity will be needed to treat metabolic disturbance of obesity.
In order to know the Korean college women students expended calorie and nutritional status, a time study and a dietary survey were carried out for ten days, in January 1962, of 28 women students in Pusan Teachers College. (1) Average age of the subjects was 20 years, the height 157.1cm, weight 51. 75kg. and surface area 1.5m$^2$. (2) The structure of their expended energy, in average, was 1303 Cal for basal metabolism, 1563 Cal for quite metabolism, 469Cal for action metabolism and 2032 Cal for spended energy. While their ingested energy was 1880 Cal, which was 152 Cal less than the expenditure. (3) Their in take of protein, iron, vitamin B$_1$ and C were found more than the amount required, while calorie, fat, carbohydrate. calcium, Vitamin A and B$_2$ were less than the amount.
The purpose of this study was to suggest an educational direction to aid in formulating a dietary life that is suited to Korea's multicultural families. This was achieved by analyzing the dietary life of immigrant women from multicultural families in Daegu. The study was carried out with 94 immigrant women form multicultural families who were served by public health center A (20 women), public health center B (47 women) and public health center C (27 women). Their home countries were China (55.3%), Vietnam (37.2%), Philippines (3.2%), Japan (2.1%), Uzbekistan (1.1%) and Thailand (1.1%). When the scores of their dietary balance were compared on the basis of the time they have been in Korea (Less than 1 year, 1~3 years, more than 3 years), we found that the score of immigrant women who stayed for less than 1 year was higher than those who stayed for more than 3 years (p<0.05) in terms of their intake of meats, fishes, potato, calcium, and carbohydrate. When subjects were asked about Korean food they wanted to learn how to cook, 30 different types of food were selected and 95.5% of the respondents wanted to learn in detail how to cook Korean food. The place most suitable for them to learn cooking was college (30.3%), while the house of their husband (2.2%) was lowest. Therefore, it seems that a college, public health center or welfare center are good places for immigrant women from multicultural families to participate in an education program that is designed to teach them how to cook Korean food.
The purpose of this study was to investigate effects of the developed nutrition education program focused on individual daily energy requirements and food exchange units using Food Exchange System for diabetes mellitus at a community health center. Developed the nutrition education program, four weeks' nutrition education including provided twice individual meal as diet therapy (2 hour/lesson/week, 4 week), was provided to 20 diabetic elderly (12 male, 8 female, 50-75 yrs): 1st lesson "Introduction: management of diabetes mellitus", 2nd lesson "6 Food groups and sources of 6 food groups", 3rd lesson "Individual daily energy requirements and food exchange units", and 4th lesson "Food choice for diabetes mellitus". For effects' analysis of the developed program, we assessed the changes in anthropometric characteristics; biochemical characteristics and nutrient intakes using 24 hr recall method. Effects of the developed nutrition education program were as follows: weight was significantly decreased, blood urea nitrogen (BUN) and glycosylated hemoglobin (HbA1c) were significantly decreased, and distribution of subjects in BUN and HbA1c was significantly changed. In protein : fat : carbohydrate (PFC) ratio, it was significantly changed from 15.98 : 16.30 : 66.69 to 17.51 : 18.94 : 64.10. In evaluation of nutrient intakes by Dietary Reference Intakes for Koreans (KDRI), protein, fiber, fat, vitamin E, niacin, folic acid, calcium and zinc were shown significantly positive changes in distribution of subjects according to intake level. The index of nutrition quality (INQ), nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) were significantly increased. In conclusion, the developed 4 weeks' nutrition education program focused on individual daily energy requirements and food exchange units using Food Exchange System for diabetes mellitus at community health center may improve the symptom of diabetes mellitus.
Objectives: This study was conducted to survey the related factors of metabolic syndrome of Chinese workers aged 20 years and above. Methods: The study was conducted at three locations in Shandong, China, currently working and took the physical examination (PE) within one year in the area as target participants. Personal characteristics, physical and biochemical results based on the PE, lifestyle habits, and food intake of the participants were used to analyze the relationship with metabolic syndrome. Results: Results showed that overall, thirty-one subjects (22.5%) had metabolic syndrome, twenty males (32.7%) and eleven females (14.2%). Metabolic syndrome was related to age, gender, educational level and occupational type with more risk in male (P < 0.05), people of older age (P < 0.001), low educational level (P < 0.05) and non-office workers (P < 0.01). According to the life style scores, lifestyle evaluation showed specifically alcohol consumption and smoking (P < 0.001) and stress management (P < 0.05) as important factors that were associated with the metabolic syndrome. High calorie (P < 0.01) and carbohydrate (P < 0.01) intakes were observed on male participants with metabolic syndrome in comparison to the non-metabolic syndrome but no significant difference on female participants. Conclusions: This results of this study can be used as significant supporting data to prevent and control metabolic syndrome in Chinese workers.

The main nutritional problem of sorghum${\times}$sudangrass hybrid (Sorghum bicolor${\times}$Sorghum sudanese) silage is low quality and palatability. This experiment was conducted to evaluate whether organic com grain and crushed rice addition of sorghum${\times}$sudangrass hybrid silage increases forage quality of the silage. The sorghum${\times}$sudangrass hybrid silages with added com grain and crushed rice were similar to conventional com silage in moisture content. However organic sorghum${\times}$sudangrass hybrid silage had low pH values. Silage added with gain and byproduct had higher crude ash, acid detergent fiber (ADF) and neutral detergent fiber (NDF) contents than control com silages, while its non-fiber carbohydrate (NFC) and total digestible nutrients (TDN) showed the opposite results. Lactic acid, butyric acid and lactic percentage of total organic acid (L/T) of sorghum${\times}$sudangrass hybrid silages were higher than those of com silage, but acetic acid was higher than control. In vitro dry matter digestibility (IVDMD) of com silage was higher than other sorghum silages. Feed intake of sorghum${\times}$sudangrass hybrid silage added with crushed rice was highest among silages. Therefore, these data indicate that crushed rice and com grain added sorghum${\times}$sudangrass hybrid silage could be recommended as the most effective treatment for increasing silage quality and palatability.
This study investigated the effects of conjugated linoleic acid(CLA) on the fat deposition, triglyceride levels and the expression of stearoyl-CoA desaturase 1(SCD1) in the livers of male ICR mice that were fed with either soybean oil or beef tallow supplemented with CLA. Mice weighing $25{\sim}30$ g were divided into four groups; soybean oil(SBO), and SBO supplemented with 1% CLA(SBOC), beef tallow(BT) and BT supplemented with 1% CLA(BTC). Each group consisted of 10 mice that were fed the experimental diets for 4 weeks. The experimental diets consisted of 64% carbohydrate, 20% protein, and 16% fat in terms of their contributions to total calories. All other nutrients were identical in the diets. Triglyceride measurements were completed using a kit. Fatty acid compositions were analyzed in the liver using gas chromatography. The levels of SCD1 expression were analyzed by RT-PCR in the liver. No significant differences were found for food intake level, body weight and food efficiency among the experimental groups. However, the weights of epididymal fat pads and plasma triglyceride levels were significantly lower in SBOC and BTC(p<0.05) compared to the SBO and BT groups. These effects were similar in the CLA supplemented groups. The expression level of SCD1 gene and ${\Delta}9$ desaturase index were not significantly different, regardless of the fat used for CLA supplementation. Based on these results, addition of CLA showed decreasing effects on the fat depots weight and the concentration of triglyceride regardless of the fat sources. The SCD1 gene expression and ${\Delta}9$ desaturase index were not influenced by the types of fats with respect to the CLA effects.
This nutritional survey was conducted from February 8 to March 10, 1994, in order to investigate the nutritional knowledge, food habits, nutritional attitude, food preferences and nutrient intakes of urban middle-aged women living in Daegu and Pohang district. The subjects of this survey were 164 urban middle-aged women living in Daegu and Pohang Area. The completely answered questionnaires were analyzed for nutritional knowledge, food habits, nutritional attitude, food preference and nutrient intakes of urban middle-aged women. The results obtained are summarized as follows: The subjects had a high level of perceived knowledge (82.9%), that is the knowledge that each subject believed she had, but the accuracy of the knowledge was only 66.1%. The average nutrition knowledge score was 8.26 out of possible 15 points, and food habit score was 5.50 out of 10 points. Most of the subjects belonged to 'Fair' or 'Good' food habit group, which is considered to be relatively good. With increasing age, the percentage of perceived knowledge, accuracy, and nutrition knowledge score were getting lower. But food habit score and nutritional attitude score were getting higher at 40's women than 30's women. The correlation between nutritional knowledge score and food habit score was low (r=0.0748). The correlation between nutritional attitude score and food habit score was low, too (r=-0.0653). Food preferences for kimchi, potato, cooked rice, beef, noodle, cabbage and milk were high. Average calorie and protein intake of the subjects were $1967.4{\pm}27.8\;Kcal$, $75.8{\pm}1.4\;g$ respectively. Carbohydrate, protein and fat ratio on energy composition was 63.3%:15.5%:21.2%.
