  • Cage layer waste and sudex grass were ensiled in the proportions of 0:100, 30:70, 40:60 and 50:50 wet basis, respectively. The influence of ensiling cage layer waste on Salmonellae, Shigella, Proteus, and total number of colony forming units (CFU) was investigated. The nutritive value of the silages was evaluated in a digestion trial. The experiment was conducted with 24 wethers allotted to four silages. Initial samples of cage layer waste showed $0.11{\times}10^6$ CFU and salmonellae, Shigella and Proteus were present. Ensiling was effective in complete elimination of all the pathogens. Dry matter, crude protein and ash contents were increased linearly (p < .01) with the increase of cage layer waste in the silages ($358g{\cdot}kg^{-1}$ to $484g{\cdot}kg^{-1}$; $76.3g{\cdot}kg^{-1}$ to $183.2g{\cdot}kg^{-1}$ and $38.5g{\cdot}kg^{-1}$ to $169.4g{\cdot}kg^{-1}$; DM basis, respectively). Water solubles carbohydrate values for silages were 38.3, 22.5, 20.1 and $20.0g{\cdot}kg^{-1}$ DM basis, respectively. Ensiling decreased the pH values for all the silages and the decrease was higher for sudex grass ensiled alone than grass ensiled with cage layer waste. Lactic acid concentration in silages increased linearly (p < .01) with the increase of cage layer waste. The apparent digestibilities of DM, OM and CP for the animals fed sudex grass silage alone were 496.0, 516.1, $496.7g{\cdot}kg^{-1}$ DM basis respectively. However, digestibilities of all the components were higher (p < 0.01) for the animals fed silages containing cage layer waste. Among waste containing diets, the digestibilities of all the components showed quadratic affect (p < 0.01), increased for silages containing 30 and 40% cage layer waste and decreased when the level of waste increased from 40 to 50%. The results indicated that cage layer waste can be used upto 40% in ruminant diet as a source of N without any adverse effect on the health of animals. Ensiling appeared to be feasible and effective method for eliminating the pathogen present in cage layer waste.

  • Objective: The aim of this study was to compare overfeeding performance, fatty acid composition, blood chemistry, enzymes and genes expression overfed Xupu and Landes geese. Methods: Sixty male Xupu geese (80 d) and Landes geese (80 d) were selected. After a period of one-week of pre-overfeeding, Xupu and Landes geese were overfed three meals of 550 and 350 g/d, respectively, of a high-carbohydrate diet in the first week of the overfeeding period. The next week, geese were given four meals of 1,200 and 850 g/d, respectively, over 8 to 14 d. Finally, geese were given five meals of 1,600 and 1,350 g/d, respectively, for the last two weeks. Results: After overfeeding for 28 d: Compared with Landes geese, Xupu geese liver weight and liver-to-body weight ratio decreased (p<0.05), while final weight, slaughter weight, total weight gain, abdominal fat weight, and feed-to-liver weight ratio increased (p<0.05). The levels of elaidic acid (C18:1t9), oleic acid (C18:1n-9), eicosenoic acid, and arachidonic acid in the liver of Xupu geese significantly increased (p<0.05), and the levels of myristic acid and stearic acid significantly decreased (p<0.05), while methyleicosanoate acid significantly increased (p<0.05). Xupu geese had higher plasma concentrations of triglyceride and very low density lipoprotein cholesterol (p<0.05), and decreased activities of alanine aminotransferase, aspartate aminotransferase, and lipase (LPS) (p<0.05). Landes geese had higher LPS activity (p<0.05), but lower cholinesterase activity (p<0.05) when compared with Xupu geese. The mRNA expression levels of fatty acid dehydrogenase (FADS) gene, elongase of long-chain fatty acid 1 (ELOVL1) gene, ELOVL5, and acyl-Co A: cholesterol acyltransferase 2 (ACAT2) gene were significantly upregulated (p<0.05) in Landes goose when compared with Xupu geese. Conclusion: This study demonstrates that the liver production performance of Landes geese was better than that of Xupu geese to some extent, which may be closely related to LPS activity, as well as the expression of FADS, ELOVL1, ELOVL5, and ACAT2.

  • This study has investigated the effect of dietary attitudes on nutritional status of nurses living in Kyungnam province. A total of 249 muses working at hospitals in the Kyungnam area participated in this study. The general characteristics and dietary attitudes of the subjects were surveyed using a self-administered questionnaire, and nutrient intakes were examined using one day 24-hour recall method from November 14 to December 20, in 2001. The data of nutrient intakes were analyzed by the Computer Aided Nutritional Analysis Program and then the diet quality was estimated using the Index of Nutritional Quality (INQ). The subjects were classified as the high score group (17.3 %), medium score group (54.2%), and low score group (28.5%) based on dietary attitude score. The results were as follows: Average age of subjects was 27.1 years old, average nursingexperience was 5.7 years, and 70.7% of the subjects graduated from a junior college. The rate of shift work (45.4%) and non-shift work (54.6%) were similar. The average score on dietary attitudes in thehigh score group was 78.8, and those in he medium score group and in the low score group were 58.6 and 40.8 out of 100 points respectively. The average intake of energy (p < 0.001), carbohydrate (p < 0.001), protein (p < 0.05), animal protein (p < 0.01), animal fat (p < 0.05), vitamin $B_1$ (p < 0.01), vitamin $B_2$ (p < 0.0l), niacin (p < 0.001), Ca (p < 0.001), Fe (p < 0.001), animal Fe (p < 0.01), P (p < 0.001), and crude fiber (p < 0.00l), were significantly higher in the high score group than those in the medium score group and low score group. In the high score group, the average intake of protein, vitamin $B_1$, niacin, vitamin C and P were above 125% of the Korean RDA, and in medium score group, those of vitamin C and P, and in low score group, that of vitamin C were above 125% of the Korean RDA. In the high score group, nutrient of intake below 75% of the Korean RDA was Ca, and those in medium score group were vitamin $B_2$, Ca, and Fe, and those in low score group were energy, vitamin $B_2$, Ca and Fe. The intake ratio of Ca and P showed an unbalanceof 1:2, and that of animal protein/plant protein, and that of animal fat/plant fat were high (1.45-1.64) in all group;. The dietary attitude had a positive correlation (p < 0.00l) with nutrition intake except vitamin A and vitamin C.

  • To increase the consumption of head-type kimchi cabbage leaves as fresh food ingredients, the physicochemical composition was investigated depending on leaf parts. Kimchi cabbage leaves were divided into three portions, such as outer (L1), mid (L2), and inner (L3), and their proximate compositions were determined along with dietary fiber, free sugar, organic acid, free amino acid, and mineral contents. Contents of moisture, crude protein, and crude fat were highest in L1, whereas contents of crude ash and carbohydrate were highest in L3 (P<0.05). Calories ranged 24.5~26.5 kcal/100 g with no significant difference among leaf parts, and dietary fiber content of L1 was highest (P<0.05). Fructose, glucose, and sucrose contents were highest in L3 (P<0.05). Citric acid, malic acid, and succinic acid were detected, and contents of citric acid and malic acid were highest in L3, in contrast, succinic acid was highest in L1 (P<0.05). Glutamic acid, constituting over 30% of the total free amino acid contents, was highest in L3, whereas ${\gamma}-aminobutyric$ acid contents were highest in L1 (P<0.05). K, Na, Ca, and Mg were the major minerals in head-type kimchi cabbage, and their contents showed no significant differences (P<0.05). It can be proposed that marketing of head-type kimchi cabbage as a fresh-cut vegetable could be enhanced due to the different quality characteristics of its leaf parts.

  • The evaluation of structural carbohydrate losses and its effect on silages digestibility in alfalfa (Medicago sativa L.) and orchardgrass (Dactylis glomerata L.) was studied during 5, 21 and 56 days ensiling. About 70 and 60 kg fresh matter of the two forages were ensiled in 9 silos of 120 L capacity. The digestion trials were conducted in two phases using the two grasses in two $4{\times}4$ Latin square design according to the four treatments being the grass and the three silages. There were no differences in the DM and CP contents resulting from 5 to 56 days ensiling in both forages. The water-soluble carbohydrates (WSC), hemicelllose, pectin, and energy were slightly reduced and appeared lower in 56 days silage. The ether extract and cellulose contents slightly increased as the ensiling process advanced in the two species. Hemicellulose losses of 29 and 41 g/kg DM were obtained in alfalfa and orchardgrass, respectively, 56 days after ensiling. While the cellulose losses in both species were very little, compared to that for hemicellulose, the pectin losses, 56 days after ensiling were 15 and 12 g/kg DM in alfalfa and orchardgras respectively. The total structural carbohydrates lost (ie., hemicellulose + cellulose + pectin) in g/kg DM of fresh material forage ensiled, is about four fifths the amount lost by WSC, in alfalfa and about two thirds, in orchardgrass, by 21 days ensiling after the activity of microorganism terminated, indicating that appreciable amount was used as substrate for silage fermentation. Ensiling alfalfa and orchardgrass for 0, 5, 21 and 56 days maintained a decreasing trend of 83.8, 82.5, 79.3 and 78.9% digestibility in alfalfa and 80.5, 77.0, 77.1 and 76.4% digestibility in orchardgrass. While the digestibility of cellulose and ether extract increased in silage in both species, the digestible energy values in silage were reduced from 2.6 to 2.3 and 2.9 to 2.7 Mcal/kg DM respectively in alfalfa and orchard during 5-56 days ensiling.

  • This study examined the effect of cane molasses and fermentation time on chemical composition and characteristics of oat grass silage (OGS) and its in situ digestion kinetics, intake, digestibility, milk yield and composition in buffaloes (Bubalus bubalis). Oat grass (OG) harvested at 50-days of age was ensiled in laboratory silos with cane molasses at the rate of 0, 2, 4 and 6% of OG dry matter (DM) for 30, 35 and 40 days. Silage pH was decreased while lactic acid content increased with increasing level of cane molasses and fermentation time. Dry matter (DM), crude protein (CP) and true protein (TP) content of OGS were (p<0.05) significantly higher with higher cane molasses levels. However, they were not affected by the fermentation time. Similar trends were observed for neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose, acid detergent lignin and ash content of OGS. The OG ensiled for 30-days with 2% molasses was screened from laboratory study and used to determine comparative in situ DM and NDF digestion kinetics of OG and its silage. In situ DM and NDF digestibilities of OG were significantly (p<0.05) higher than OGS. Ruminal DM and NDF lag time, rate and extent of digestion of OG and its silage were similar. Two experimental diets of OG and OGS were formulated using 75:25 forage to concentrate ratio on a DM basis. Dry matter and CP intakes were similar in lactating buffaloes fed either OG- or OGS-based diets. However, NDF intake was higher in buffaloes fed the OG-compared with OGS-based diet. Apparent DM, CP and NDF digestibilities were similar in lactating buffaloes fed either OG- or OGS-based diets. Milk yield (4% FCM) was similar in buffaloes fed either OG-(10.3 kg/d) or OGS-(9.95 kg/d) based diets. Milk fat, total solids and true protein content were higher with OG compared with the OGS diet. Solids not fat and CP content were similar in milk of buffalo fed either OG or OGS. The results of this study indicate that OG ensiled with 2% molasses could safely replace 75% DM of green oat fodder in the diets of lactating buffaloes without negatively affecting intake, digestibility, milk yield and composition.

  • The effect of three different grains supplemented diet as a dietary carbohydrate source on the growing rat, growth, food intake, FER and PER value, excretion of urinary arid fecal nitrogen and glucose and the level of glucose and cholesterol in serum blood was studied. Forty males and same number of females of Albino rats weighing male $58{\pm}2g$, female$62{\pm}2g$ were divided into eight experimental group, five male and female in each and fed rice diet, rice supplemented with wheat and rice supplemented with barley diet for 14 weeks. Under this condition wheat supplemented diet group shows the best FER, PER and body weight gain value. Especially in female group shows better FER, PER and body weight gain value compare to control diet group. Under the male groups wheat supplemented diet group shows lower FER, PER value and body weight compare to the control group but higher than those of barley diet group or rice alone. In female group the nitrogen retention shows also highest value by wheat supplemented diet group. By male group the wheat supplemented diet group shows not better value compare to the control group, but higer than barley supplemented group or rice alone. The nitrogen excretion through feces was significantly higher by grain supplemented diet group compare to grain the 20% sugar casein diet. The blood cholesterol content was slightly decreased by the control group which was fed disaccaride, compare to groups which were fed polysaccaride. But the free cholesterol to esterified cholesterol ratio shows lower value by control group than grain groups except the 70% rice supplemented with 30% barley group.

  • We examined the effect of dietary behavior improvement on diet quality, body composition and blood lipid profiles in 68 middle-aged women. Dietary behavior intervention was consisted of counselling in the problem areas of portion control, food selection for low carbohydrate and high fiber food items, and education on the improvement of micronutrient intakes and diet quality. The subjects were divided into two groups; Improved or Not-Improved Group according to the level of changes in dietary behavior scores. After 6 months, body weight, BMI, waist-hip ratio, and visceral fat area were significantly decreased in the Improved Group compared to the Not-Improved Group. Calorie-adjusted protein, fiber, calcium, iron and vitamin C intakes were significantly increased in the Improved Group. The index of nutritional quality (INQ) and mean adequacy ratio (MAR) were increased only in the Improved Group. We observed a significantly increase in HDL-cholesterol and a decrease in total cholesterol, triglyceride and LDL-cholesterol, and an improvement of atherogenic index in the Improved Group. These results showed that dietary behavior intervention improved dietary behavior scores, and those whose dietary behavior score improved showed more improvement in diet quality, body composition, and serum profiles than those whose dietary behavior score did not improve.

  • This study examined the effects of the biological markers and lifestyle factors on the presence of diabetes in middle-aged adults. A total of 5,363 adults aged 40-64 years were recruited from the 2010-2012 Fifth Korean National Health and Nutrition Examination Survey. The data were analyzed by descriptive statistics, Chi-square test, ANCOVA and logistic regression. The results were as follows. The body mass index was significantly higher in the prediabetes and diabetes group than in the normal group. Hypertension, abdominal obesity, hypercholesterolemia, hypertriglyceridemia, smoking, drinking, and carbohydrate intake were significantly different among three groups. Hypertension, hypercholesterolemia, hypertriglyceridemia, abdominal obesity, body mass index and drinking were the influencing biological markers and lifestyle factors in prediabetes. The significant factors influencing diabetes were hypertension, hypercholesterolemia, hypertriglyceridemia, abdominal obesity, body mass index, and smoking. Overall, the development of intervention programs for effective diabetes prevention in middle-aged adults by lifestyle modification of hypertension, obesity, dyslipidemia, drinking, and smoking is recommended.
