An experiment was conducted to evaluate the effect of replacing barley and soybean meal in finishing diets with sesame hull (SH) on growth performance, digestibility, and carcass characteristics of Black goat kids. Twenty-one Black goat kids were assigned randomly to 0%, 10%, or 20% SH diets (7/diet). The study lasted for 63 d. Intakes of dry matter (DM), organic matter (OM), and crude protein (CP) of kids fed the 10% diet were greater (p<0.05) than for the 0% and 20% SH diets (p<0.10). Neutral detergent fiber (NDF) and acid detergent fiber (ADF) intakes were highest (p<0.05) for kids fed the 10% SH diet when compared to 0% and 20% SH diets. Ether extract (EE) intake was greater (p<0.05) for kids fed 10% and 20% SH diets when compared to 0% SH. Digestibilities of DM, OM, CP, NDF, and ADF were similar among all diets. However, sesame hull inclusion increased (p<0.05) EE digestibility. Final body weight, total gain, average daily gain (ADG), and feed conversion ratio were comparable among all diets. Cost of gain was lower (p<0.05) in kids fed 20% SH than the 0% SH diet, while there was no difference between the 10% SH diet and the other two diets. Dressing percentage, hot and cold carcass weights, non-carcass components, carcass cut weights, and meat quality parameters were not influenced by SH. Total fat percentage in the leg was greater (p<0.05) on 0% SH than on the 10% SH diet. Results of this study demonstrated that inclusion of sesame hull at levels of 10 or 20% did not influence the performance of Black goat kids, but the cost of gain was lower.

Fifty-four, mixed-sex, halothane-carrier crossbred (Yorkshire${\times}$Landrace) pigs with an average initial BW of $108.2{\pm}0.8$ kg were randomly allotted to one of three dietary treatments for 5 d before slaughter: i) a control corn-soybean meal finisher diet devoid of supplemental magnesium; ii) a diet supplemented with 1.5 g/kg of elemental Mg from magnesium acetate; and iii) a diet supplemented with 1.5 g/kg of elemental Mg from magnesium sulfate heptahydrate. Serum creatine kinase (CK), lactate and glucose were analyzed at slaughter. Muscles from longissimus (LM) were packaged and stored to simulate display storage for muscle lactate and glycogen determinations at 0, 1, 2, 3, and 4 d. Mg supplementation reduced (p<0.05) serum CK and lactate concentration, but had no effect (p>0.05) on serum glucose. Daily change of muscle lactate concentration linearly increased (p<0.01), while glucose concentration linearly decreased (p<0.05) as storage time increased in all treatments. However, dietary Mg acetate and Mg sulfate supplementation in pigs elevated (p<0.05) muscle glycogen and reduced (p<0.05) muscle lactate concentrations, especially during the first 2 d of display, compared with pigs fed the control diet. This study suggests that short-term feeding of magnesium acetate and magnesium sulfate to heterozygous carriers of the halothane gene has beneficial effects on stress response and pork quality by improving blood and muscle biochemical indexes.

The objectives of this study were to determine the effects of substituting bread by-product (BBP) for barley grain in high concentrate fattening diets for kids on nutrient intake, growth performance, and nutrient digestibility. Twenty-eight Baladi kids (body weight=17.1${\pm}$1.0 kg) were assigned randomly to 4 experimental finishing diets (7 kids/treatment) in a completely randomized design for 70 days. The control (CON) diet contained 20, 60, 11, 7 and 2% (DM basis) alfalfa hay, barley grain, soybean meal, corn grain, and mineral and vitamin mix, respectively. Bread by-product substituted barley grain by 10, 20 and 30% of the diet DM in the LBBP, MBBP, and HBBP diets, respectively. Dry matter intakes for the CON, LBBP and MBBP diets were similar (p>0.05; avg.=592 g/day), however, kids fed the HBBP diet had a lower (p<0.05) DM intake (451 g/day). Organic matter and CP intakes showed similar patterns to that observed for DM. Dietary treatments did not affect (p>0.05) average daily gain for kids fed the CON, LBBP and MBBP diets (avg.=150 g/day). Final body weights for kids fed the CON, LBBP and MBBP diets (avg. 27.1 kg) were greater (p<0.05) than for kids fed the HBBP diet (23.7 kg). Feed to gain ratio was greater for the CON, LBBP and MBBP diets (avg. 3.9) compared with the HBBP diet (5.0). No significant (p>0.05) effect of the dietary treatment was observed for DM, OM and NDF digestibility. Substituting BBP for barley grain up to 20% of the diet DM did not affect nutrient intake, growth performance and nutrient digestibility of kids and resulted in a decrease in feed cost.

Fifty four crossbred gilts of 26.38${\pm}$0.85 kg body weight and 25 weeks of age were randomly divided into three groups, having six replicates of three animals each and were assigned to one of the three dietary treatments containing corn, wheat bran and rice bran (RB) at 35, 47 and 0% in $R_1$; 17.5, 23.5 and 41% in $R_2$ and 0, 0 and 82% in $R_3$. Soybean meal and fishmeal were used as source of protein at 10 and 6%, respectively, in all the rations. Average daily CP, DCP, DE and ME intake per kg $W^{0.75}$ and body weight gains were lowest (p<0.01) in gilts fed 82% RB ($R_3$), followed by $R_2$ and R1. Utilization of protein with respect to nitrogen balance and DCP conversion efficiency did not differ (p>0.05) between the treatment groups. All the gilts were in positive nitrogen balance. However, the excretion of dietary nitrogen and energy through faeces was higher (p<0.01) in gilts fed RB. However, the DE and ME conversion efficiency were higher (p<0.01) in gilts fed RB. Therefore, it can be concluded that the digestibility of energy and protein in diets containing rice bran goes on decreasing with the increasing level of fat and fibre, but the metabolizability of the energy and protein was better in pigs fed RB in the diet.

The effects of ${\beta}$-glucosidase on the overall growth performance and a set of physiological parameters of broilers were investigated. 240 male, one-day old Avine broiler chickswere randomly allocated to four treatment groups and fed with a corn-soybean meal supplemented with 0% (control), 0.2%, 0.4% and 0.6% ${\beta}$-glucosidase. The 0.2% ${\beta}$-glucosidase group, but not the 0.4% and 0.6% ${\beta}$-glucosidase groups, showed a significantly increased average daily weight gain (p<0.05) over that of the control. All three ${\beta}$-glucosidase feed groups showed significantly higher feed conversion ratios than the control group (p<0.05). Feed supplementation of 0.2% ${\beta}$-glucosidase significantly raised the contents of serum isoflavone aglycones as shown by decreases of genistin and daizin (p<0.01) and an increase of daidzein (p<0.01). The 0.2% ${\beta}$-glucosidase feeding significantly increased the intestinal amylase activity while it had little effect on lipase and trypsin activities (p>0.05). 0.2% ${\beta}$-glucosidase feeding also significant elevated the levels of highdensity lipoprotein cholesterol and malate dehydrogenase while lowering the level of low-density lipoprotein cholesterol (LDL-C). Finally, ${\beta}$-glucosidase improved the anti-oxidative activities of the animals; the 0.2% ${\beta}$-glucosidase feed group had higher activities of superoxide dismutase (p<0.05), glutathione peroxidase and glutathione reductase in the liver (p<0.05), and malondialdehyde level in the serum (p<0.05).

We compared the utilization efficiency of free lysine (FL) and dipeptide lysine-glycine (LG) in terms of growth performance and whole-body amino acid composition in olive flounder Paralichthys olivaceus. A basal experimental diet was formulated to contain 0.5% (basal) lysine from fish meal, and four other diets were prepared by supplementing 0.5% or 1.0% of either FL or LG. The experiment was performed in triplicate, and 20 randomly selected fish averaging $5.41{\pm}0.16g$ were fed one of the test diets at the rate of 3% BW/day twice daily for 6 weeks. At the end of the feeding trial, fish fed the basal diet showed significantly less weight gain than did the other groups. The results of a two-way ANOVA showed that both lysine level (P = 0.001) and type (P = 0.034) influenced growth rate; however, we found no significant interaction between lysine level and form (P > 0.05). Our results revealed a significant improvement in protein efficiency ratio (PER) with each increment of dietary lysine, and the groups fed LG-supplemented diets showed higher PER than did those offered FL. Hepatosomatic and viscerosomatic indices were significantly influenced by lysine level and form, and higher values were recorded in fish fed diets containing LG. Significantly higher whole-body arginine levels were found in LG-fed groups, and a significant interaction was observed between lysine level and form (P = 0.009). Whole-body valine and aspartic acid contents were affected by lysine level, and alanine concentration was influenced by both lysine level and form. Our findings indicate that juvenile olive flounder can utilize LG more efficiently than FL for protein synthesis.

To assess the dietary therapy compliance of non-insulin-dependent diabetes mellitus (NIDDM) patients living in Daegu, we evaluated diet adequacy levels by index of nutritional quality (INQ), nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and dietary variety score (DVS) with food exchange system and Korean recommended dietary allowances (KRDA). One day dietary intake was measured by 24 hour recall method for 229 subjects over 20 years of age. Average daily energy intake was 1444 kcal. The relative ratio of carbohydrate, protein and fat in terms of energy intake was 69.4：14.5：16.0. The nutrient adequacy ratio (NAR) for Vitamin A, B$_2$, calcium were lower than 0.5 and MAR was 0.65. It appeared that the consumption of each food group as compared to prescribed food exchange unit was insufficient, in the order of dairy group (10.2 $\pm$ 25.2%), fruits group (58.2 $\pm$ 71.2%) and oils & fats group (42.9 $\pm$ 42.0%). The dietary variety score (DVS) was evaluated as an useful tool for diabetes' meal management when we accept minimum intake as 0.3 of food exchange unit. We found significant correlation between food groups and anthropometric indices: cereals group and % total body fat (r = 0.251, p < 0.01), meat group and waist circumference (r = 0.241, p < 0.01), vegetables group and WHR(r = 0.139, p < 0.05), and oils poop and WHR(r = 0.165, p < 0.05). from these results, we concluded that overall status of dietary intake of NIDDM patients in Daegu area was insufficient not only in quality but also in quantity. It is suggested that nutrition education for NIDDM patients should stress on balanced food consumption to meet proscribed amount by six food group to improve the inadequacy of dietary status.

The aqueous extract of Schisandra chinensis, Evodia rutaecarpa and meal (SEM-Ex) has been traditionally used in the Oriental countries as an astringent. However, little is known about the effects of aqueous extract of SEM-Ex on dextran-sulfate sodium (DSS)-induced colitis in mice. In this study, we investigated the protective effects of SEM-Ex on DSS-induced colitis in mice. An experimental colitis was induced by daily treatment with 5% DSS. SEM-Ex was orally administered from day 2 of DSS treatment in the different dose (10-50 mg/kg body weight). SEM-Ex reduced significantly clinical sign of DSS-induced colitis, including body weight loss, shorten colon length, increased disease activity index (DAI), and histological colon injury. Moreover, SEM-Ex suppressed significantly not only the serum haptoglobin levels and the activities of myeloperoxidase (MPO), but also the colon tissue expression levels of monocyte chemoattractant protein-1 (MCP-1) in DSS-induced mice. In contrast, SEM-Ex increased significantly the colon tissue expression levels of granular colony stimulating factor (G-CSF) well known as anti-inflammatory cytokine. These results suggest that SEM-Ex administration could reduce significantly the clinical signs and regulate of chemokine and anti-inflammatory cytokine in DSS-induced model mice. Therefore, these properties may contribute to the strong anti-ulcerative colitis (UC) response effect of SEM-Ex.

This study was designed to develop a website for providing nutrition information and education for college women and young women. The website focuses on two topics ; general nutrition and desirable weight control. This program is located at http : // www.ezydiet.co.kr. This program is composed of 5 major sections. The first two sections were designed to provide information ; one for general nutrition, and the other for providing information regarding weight control. The first section includes information regarding young adult women's diet, nutrition standards, such as the RDA or Korean Food Pyramid, drinking and smoking. The second section coveres information regarding desirable control, foods with high or low calories, eating disorders and popularly used dieting methods. The third section is for simple nutrition assessment, consisting of assessment of ideal body weight and obesity, energy requirements, and eating habits. The fourth section was designed to introduce and help users to apply behavioral modification techniques, such as monitoring, goal setting, stimulus control and reinforcement. The final section was designed for meal planning, by introducing a food exchange list and menu examples for one week. The characteristics of this web-based program are as follows ; 1) provide nutrition information systematically, 2) involve sections for the participation of the user, 3) include food pictures to help understanding of nutrition information, 4) include management modules for some sections to revise or update the information. One-hundred and ten female university students participated in the evaluation of this website. The evaluation results were favorable. About 90% of subjects rated that this program covers major topics 'well ' or 'very well', and that it was 'easy'to 'very easy'to understand the contents on website. Two-thirds of subjects rated quite positively on questions regarding attractiveness, overall quality and technical quality of website. In addition, about three-fourths of subjects answered that this website was helpful in increasing nutrition knowledge and in applying nutrition information into daily life. These results suggested the possibility of using a website as a means of providing nutrition information and education for young adult women.

Objectives: This study was conducted to examine the effects of nutrition education with a dietary guidebook for children on dietary attitude, nutrition knowledge and nutrient intakes. Methods: The subjects were 54 higher grade elementary students (27 educated vs. 27 non-educated). The educated group was provided individual and/or group lessons (40 min/lesson/week, 4 week) using a dietary guidebook of Children developed by The Korean Society of Community Nutrition (KSCN) & Korean Food and Drug Administration (KFDA). The contents were Balanced Diet, Smart Food Choices, Cooking a Healthy Snack and Building a Healthy Body. We examined the differences in nutrition knowledge, dietary attitudes and dietary intake between the educated group and non-educated group. Results: After education, the educated group improved dietary attitude, nutrition knowledge and qualitative nutrient intakes compared to the non-educated group. Specifically, among dietary attitudes, 'taking a meal with salty and spicy food' increased, while among nutrition knowledge, 'functions of protein', 'functions of fat', 'foods with carbohydrates', 'foods with fat', 'foods with vitamins', and 'foods with minerals' were increased. Nutrition adequacy ratio (NAR) scores for vitamin C, iron, and zinc were increased. Conclusions: Nutrition education using a dietary guidebook for children developed by the KSCN & KFDA had positive effects on nutrition knowledge and qualitative nutrient intakes. These findings suggest that nutrition education focused on personalized daily energy and nutrient requirements may improve dietary attitude and quantitative nutrient intakes of children.
