This study was conducted to evaluate feeding value of berseem and lucerne silage as a replacement for conventional fodder (berseem fodder) in lactating Nili buffaloes. Fifteen early lactating multi-parous Nili buffaloes, five buffaloes in each group were allotted three experimental diets. Berseem and lucerne fodders were ensiled at 30% DM (wheat straw was used to adjust the DM of fodders) with molasses (at the rate of 2% of fodder DM) in two bunker silos for 30 days. The diets contained 75% DM from berseem fodder (BF), 75% DM from berseem silage (BS) and 75% DM from lucerne silage (LS). Each diet contained 25% concentrate DM. Diets were mixed daily and fed twice a day at ad libitum intakes. Dry matter intake (DMI) was significantly higher (13.8 kg/d) in buffaloes fed BF diet than those fed LS (12.5 kg/d) and BS (11.9 kg/day) diets. The differences in digestible DMI and DMI as percent body weight were significant between fodder and silage based diets but non-significant when BS and LS were compared. Lower DMI with silage-based diets was probably because of low silage pH. Intake of NDF (NDFI) was higher (5.68 kg/d) in buffaloes fed BF diet followed by those fed LS (5.50 kg/d) and BS (5.00 kg/d) diets. The difference was significant (p<0.05) across fodder and silage based diets but NDFI was non-significant across both silage-based diets. The apparent DM digestibility was significantly different (p<0.05) between fodder and silage-based diets but was non-significant between LS and BS diets. Four percent fat corrected milk yield was significantly different (p<0.05) between fodder and silage-based diets but was non-significant between LS and BS diets. Higher milk yield with fodder based diet was because of more digestible nutrient intake (Table 3) compared with silage based diets. Milk CP, TP and NPN and SNF did not show any treatment effects. The present results indicated that the berseem and lucerne fodder ensiled at 30% DM level with 2% molasses could safely replace (75% DM) the conventional leguminous fodder in the diets of lactating Nili buffaloes.

This experiment was conducted to investigate the influence of dietary supplementation of granite porphyry (GP) on growth performances and meat sensory quality in commercial broiler chicks. A total of four hundred-fifty 5-day-old male broiler chicks were divided into 15 pens and fed one of five experimental diets for 5 weeks; 0% GP with antibiotics (Control), 1% GP with or without antibiotics, and 2% GP with or without antibiotics. Final body weight and daily weight gain of all GP supplemented groups were slightly higher than those of control. Feed conversion rate was improved in GP 1 % supplemented groups, although there was no significant difference. Feeding antibiotics in addition to GP did not influence the growth parameters. Relative weights of liver and abdominal fat tended to be reduced in broiler chickens fed GP supplemented diets. Feeding of 2% GP diet resulted in a significant improvement in meat sensory quality in terms of taste and tenderness(P < 0.05), but the effect of the 1% GP on meat sensory quality was not significant. The results of this study indicate that GP could be used as a favorable feed additive for production of sensory-enhanced broiler meats.

Effects of feeding browses on growth and meat quality of Korean native goats were investigated. Twenty eight heads of male goats were divided into four treatment groups fed diets containing oak browse, pine browse, fermented pine browse, and rice straw. Growth rate, feed intake, carcass and meat quality and blood and serum criteria were investigated. The highest average daily gain of goats was 45.3g from oak browse, and goats on pine browse gained similar to those on fermented pine browse. Daily forage intake was 197g DM for oak browse and 74g DM for fermented pine browse. Feed efficiency(g feed/g gain) of oak browse was 11.0g and that of pine browse was 15.1g. From the results of serological inspection, metabolism in body was normal with all the browses tested. Dressing percentage was 45.1~46.2% and meat percentage was 55.2~55.9% without significant differences between diets. Fat percentage of goat carcasses fed rice straw was higher than those fed pine browse or fermented pine browse which was, however, not significantly different from those on oak browse. Shear force and coking loss of goat meat on pine browse or fermented pine browse was less than those on rice straw(p〈0.05) without significant differences between other browses. Juiciness, tenderness, and flavor of the goat meat were the better(p<0.05) from the pine browse diet than from rice straw.

Pancreatic lipase and ${\alpha}$-amylase inhibitory activities in purified extracts of pumpkin and job's tear were studied. Pancreatic lipase inhibitory activity was determined by measuring the rate of releasing oleic acid from triolein, and ${\alpha}$-amylase inhibitory activity was determined by iodometric method. The extracts of pumpkin and job's tear were purified using silica gel and C-18 gel column chromatographies. Treatment of pumpkin extract $(120\;{\mu}g/mL)$ in 3T3-L1 preadipocyte decreased differentiation about 95% and blocked accumulation of lipid. Body weights of rats fed high-fat diet containing dietary supplement decreased about 13% as compared with those fed only highfat diet. These results revealed dietary supplement is a good obesity-reducing material for decreasing lipid and carbohydrate absorptions.

To compare the hypolipidemic effects of perilla oil with different kinds of dietary fat and oil forty eight 20 days old male Wistar rats were fed one of the following diets for 4 weeks: basal diet for control containing 9.4 w/w% corn oil(CO), 9.4 w/w% beef tallow (BO), 9.4 w/w% perilla oil(PO) and 4.7 w/w% beef tallow plus 4.7% perilla oil(BP). The amount of diet consumed and body weight gain rate were not significantly different among the four dietary groups. The levels of plasma triglyceride and total cholesterol in PO group were significantly lower than those of BO and BP groups. PO group also had significantly lower LDL-cholesterol in BP group were than other groups. The levels of plasma triglyceride tatal-cholesterol and LDL-cholesterol in BP group were significantly lower than those in BO group by 9.2%, 10.3% and 18.6% respectively. Plasma glutamic oxaloacetic transferase and alkaline phosphatase activities and uric acid levels in PO group were significantly higher than other groups and were somewhat beyond the normal levels. These findings showed that perilla oil with hypolicpidemic effects could have some adverse effects on hepatic and other organic functions in rats.

Cardiovascular diseases are the leading cause of death and disability in Korea. Their risk factors can be classified as either modifiable or nonmodifiable and among modifiable factors are high bood pressure, elevated blood cholesterol, obesity and cigarette smoking. The purpose of this study was to evaluate the risk factors for the cardiovascular diseases in a rural community and to get basic data for the development of a community-based rick reduction intervention program. Evaluation involved population-based, cross-sectional samples of adult residents in a rurual community. We measured blood pressure, body fat percent by bioelectric impedance fatness analyzer and serum cholesterol and interviewed adult residents over 20-year-old age. Blood pressure was checked twice and hypertension was classified by the sixth report of the Joint National Committee on Detection. Evaluation, and Treatment of High Blood Pressure. The Cutpoints for high blood cholesterol was used National Cholesterol Treatment Guidelines and those for obesity was 25% in male. 30% in female. The results were as follows: 1. Prevalence of definitive hypertension was 59.7% in males and 54.4% in female. 2. Prevalence of hypercholesterolemia was 14.3% in male and 18.2% in female. 3. Prevalence of obese was 10.7% in male and 41.1% in female. 4. Among definitive hypertension, hypercholesterolemia, and obesity 52.1% possessed one risk factor, 12.6% two risk factors and 2.5% three risk factors in males. In females 41.4% possessed one risk factor and 27.6%. 5.7% respectively. 5. The smoking rate was 65.8% in males and 5.2% in females. Our results are used effectively for the community-based intervention towards cardiovascukr diseases risk reduction. However, because of limitations in our study design, further datas are needed including other risk factors and in-person clinical datas.

The present study was to elucidate such a relationship by comparing the coronary risk factors with and without fatty liver adjusted for age and/or BMI. Study subjects were 665 women of 30 years and over, who underwent health package check-up at the health promotion center of an university hospital from July, 2009 to June, 2010. As a results, the prevalence rates of fatty liver of study subjects were 11.6%, and the rates were significantly higher in older age group, in the group of higher level of BMI. The group of subjects with fatty liver had significantly lower mean HDL-cholesterol and higher levels of body fat rate, TG, TC, LDL-cholesterol, FBS and ALT, then those parameters in subjects without fatty liver, even after adjustment for age and/or BMI. In age and BMI adjusted logistic regressions, The odds ratio of fatty liver was increased significantly as there is an increase in the abnormal group with TG, TC, LDL-C and ALT.

The purpose of this study was to examine the blood pressure, serum lipid levels and obesity indices according to smoking status, and the effects of smoking cessation on blood pressure, serum lipid and obesity indices. The 2,230 male workers aged 30-59 years were observed the age, smoking status, SBP, DBP, TC, TG, HDL-C, LDL-C, AI, BMI, body fat rate and waist circumference, from April to July, 2011. As a results, the mean score of SBP, DBP, TC, TG and BMI were significantly higher in smoking group than non-smoking group, but HDL-C were significantly lower in smoking group than non-smoking group, the distribution of hypertension was significantly higher in smoking group than non-smoking group. The abnormal levels of TC, TG and HDL-C were significantly higher in smoking group than non-smoking group, and the distribution of obesity was significantly higher in smoking group than non-smoking group. Age adjusted odds ratio(ORs) was significantly increase in smoking group than non-smoking group: hypertension(3.59 times), hypercholesteremia (1.49 times), hyperlipidemia(1.81 times), low HDL-cholesteremia(1.58 times), high level of atherogenic index(1.27 times). Above results suggested that the smoking related with blood pressure and serum lipid levels.

This study was carried out to estimate the effects of loess ($0\%$, $1.5\%$, $3\%$ and $5\%$) on the growth performance, meat quality, and blood composition of broiler chicks. A total of 320 broiler chicks at 1 day of age were divided into 4 groups to feed basal diet (control) and basal diet plus $1.5\%$ to $5.0\%$ loess respectively for 6 weeks. The body weight gain and feed conversion rate were not significantly different among the groups. The contents of moisture and crude fat of meats were significantly different in treatments when compared to that of the control group (P<0.05), but did not show any differences among the groups. The pH values of meats were not different among the treatments. However, water holding capacity was higher in all treated groups than the control. The L of meat color was also increased in all treated groups, but a and b of meat color were not different among the groups. In addition, the contents of unsaturated fatty acid content of meat were higher in the treated groups than the control. The concentrations of HDL cholesterol and triglyceride were significantly lower in all treated groups than the control (P<0.05). Finally, the contents of moisture of excreta were significantly lower in all treated groups than control (P<0.05). Taken together, it was concluded that loess did not improved the growth performance, but had effects on the improvement of meat quality.

This study was conducted to investigate dietary factors, bone status, and bone loss in postmenopausal women in rural areas. A total of 189 women participated in the follow-up study after two years. Radius, Tibia, and Phalanx SOS (Speed of Sound) was measured on two occasions 2 years apart by ultra-sonic-metry, and % body fat was measured by bioelectrical impedance analysis at the baseline and after 2years. Dietary intake data were collected 4 times at different season by 24-hour recall method, and then calculated as average. Bone density of radius decreased by 4.2% during the two year period. When the subjects were divided into three groups, by bone decline level during two years, the lowest bone loss group had higher potassium and vegetable intake than other groups. Age and calcium intakes showed significant correlation with bone decline rate at tibia. In multiple regressions, the baseline SOS, vitamin A, vegetables and eggs intakes were found to be significant factors for tibia bone decline. In conclusion, dietary factors, such as higher vegetable intake, seem to affect the changes in bone mineral density in more favorable way. Therefore, efforts are needed to enhance the access to nutritional care for rural elderly postmenopausal women.
