Objective: Since very little information exists about the topic; in this experiment we compare, in a long-term finishing program, the growth-performance responses and carcass characteristics of Holstein steers where non-structural carbohydrate concentration of the diet is reduced from 64% to 51% (dry matter basis). Methods: Sixty Holstein steer calves ($129{\pm}2.2kg$) were blocked by initial weight into five groups and randomly assigned within weight groupings to 10 pens. Calves were fed with a steam-flaked corn-based finishing diets containing 51% higher fiber (HF) or 64% lower fiber (LF) nonstructural carbohydrates. Non-structural carbohydrates concentrations were manipulated substituting dried distiller grain with solubles and alfalfa hay for flaked corn. Cattle were weighed every 112 days and at the end of the experiment (day 308) when the cattle were harvested and carcass characteristics were evaluated. Results: Steers fed the HF diet showed improvement (8.8%) in average daily gain (ADG) during the initial 112-d period. This effect was followed by a numerical trend for greater ADG throughout the remainder of the study so that overall ADG tended to be greater (4.9%, p = 0.06) for the HF than for LF. There were no treatment effects on dry matter intake. Gain efficiency and estimated dietary net energy (NE) were greater 8.3% and 5.2%, respectively for HF during the initial 112-d period. Overall (308-d) gain efficiency and estimated dietary NE were similar for both dietary treatments. However, due to differences in tabular dietary NE, the ratio of observed:expected dietary NE tended to be greater (4.1%, p = 0.06) for the HF vs LF diet. There were no treatment effects on carcass characteristics except for a tendency toward a slightly greater (0.5%, p = 0.09) estimated carcass yield. Conclusion: Reducing the non-structural carbohydrate concentration of a conventional steam-flaked corn-based growing finishing diet for Holstein steers can effectively enhance growth performance, particularly during the early growing and late finishing phases.

Objectives: This study examined the association of the total diet quality with the incidence risk of metabolic syndrome constituents and metabolic syndrome among Korean adults. Methods: Based on a community-based cohort of the Korean Genome and Epidemiology Study (KoGES) from 2001 to 2014, data from a total of 5,549 subjects (2,805 men & 2,744 women) aged 40~69 years at the baseline with a total follow-up period of 38,166 person-years were analyzed. The criteria of the National Cholesterol Education Program Adult Treatment Panel was employed to define metabolic syndrome. The total diet quality was estimated using the Korean Healthy Eating Index (KHEI). Hazard ratios (HR) and 95% confidence intervals (CI) for risk of metabolic syndrome constituents and metabolic syndrome in relation to KHEI quintile groups was calculated by multivariate Cox proportional hazards regression model. Results: After adjusting for age, energy intake, income, education, physical activity, smoking, and drinking, the incidence of abdominal obesity and high blood pressure was significantly lower, by approximately 29.7% (P < 0.01) and 25.2% (P < 0.01), respectively, in the fifth KHEI quintile compared to the first quintile in men. A significant decreasing trend of the metabolic syndrome incidence was observed across the improving levels of KHEI (HRq5vs.q1: 0.775, 95% CIq5vs.q1: 0.619~0.971, P for trend < 0.01). In women, the incidence of abdominal obesity and metabolic syndrome was significantly lower, by approximately 29.8% (P < 0.01) and 22.5% (P < 0.05), respectively, in the fifth KHEI quintile compared to the first quintile adjusting for multiple covariates. On the other hand, the linear trend of metabolic syndrome risk across the KHEI levels did not reach the significance level. Conclusions: A better diet quality can prevent future metabolic syndrome and its certain risk factors among Korean men and women.

The purpose of this study was to evaluate importance and performance of dietitian's task at long term care hospitals foodservices in the Busan Kyongnam area. The research was performed through using questionnaires and conducted from June 11 to July 16, 2010 for 186 dietitians at 141 long-term care hospitals. Seventy-two percent of hospitals had two dietitians and 69% of them had a dietitian's office. Fifty-two percent of dietitians has worked for less than 2 years at long term care hospital, and 37.1% of them worked additional tasks. Seventy-three percent of hospitals conducted a therapeutic diet program and the therapeutic diets frequently provided were diabetic diet > tube feeding diet > dysphasia diet > sodium controlled diet. Mean score for the importance (4.36/5.00) and performance (3.91/5.00) of dietitian's tasks were significantly different (p < 0.001). The importance and performance grid showed that the purchase-inspection management and sanitation-safety management were high scores to the importance and performance (doing great area), menu-foodservice management and cooking-working management were low scores to the importance and high scores to the importance (overdone area), and nutrition management was low scores to the importance and performance (low priority). Forty-three percent of dietitians agreed with the needs for role separation between foodservice dietitian and clinical dietitian.

Objective: The effects of adding fermented feed to a pelleted total mixed ration (PTMR) on the growth performance of lambs remain unclear. The present study aimed to investigate the feed efficiency and productivity of lambs that were fed PTMR containing fermented soybean meal (FSM) or wheat bran (FWB). Methods: Sixty 90-d-old hybrid lambs were randomly allocated into 12 pens (5 lambs/pen) that were randomly assigned to 4 dietary treatments (3 pens/treatment) with PTMR (basal diet), 2% FSM, or Lactobacillus- or yeast-FWB (L-FWB or Y-FWB) addition in the basal diet. Results: The findings showed that lambs fed 2% FSM supplemented diet had enhanced (p<0.05) average daily gain (ADG) and carcass yield (p = 0.015), while they had a decreased (p = 0.006) feed conversion ratio compared to that of other three groups. Inclusion of FSM or FWB in PTMR improved (p<0.05) the nutrient digestibility, while it reduced the urea nitrogen content in serum compared to the PTMR group. Additionally, the decreased ratio of N excretion to ADG (p<0.01) was observed with FSM and L-FWB supplementation compared with the PTMR and Y-FWB groups. Conclusion: In conclusion, feeding the fermented feed-supplemented diet improved nutrient digestibility and growth performance, and 2% FSM-supplemented diet exhibited superior production-promoting efficiency to lambs.

통곡물 시리얼(Whole grain cereal, WGC)이 함유된 식이는 에너지 대사 조절에 중요한 다량영양소(macronutrients)를 제공한다. 본 연구는 고지방식이(high-fat diet, HFD)로 유발된 비만 마우스를 이용하여 WGC의 근감소성 비만 예방 효과에 대해 평가하였다. C57BL/6N 마우스에 정상식이(normal diet, ND), ND+WGC, HFD, HFD+WGC를 12주 동안 제공하였다. WGC는 체중, 식이효율, 체지방 및 지방세포의 크기를 감소시켰다. 또한, WGC는 간 무게 및 간에 축적된 지방을 감소시킴으로써 HFD에 의한 비알코올성 지방간을 개선시켰다. 더욱이, WGC는 비만 마우스 및 정상 마우스의 근육 무게 및 근력을 증가시켰다. 따라서, WGC는 지방 축적을 억제하고 근육량을 증가시키므로 근감소성 비만 예방을 위한 기능성 식품으로 사용될 수 있을 것으로 기대된다.

The purposes of this study was to evaluate an occupational health promotion program for the prevention of cardiovascular disease. Method: This study employed a quasi-experimental non-equivalent pre and post test to evaluate the program. The subjects of this study were 48 employees selected by convenience sampling who were suspected of having hypertension and hyperlipidemia in routine physical examinations and who were working in A University Hospital in Suwon. 25 subjects were assigned to the experimental group and 23 to the control group. Data collection was done using questionnaries before and after the subjects used the program. Results: The results of this study showed that systolic blood pressure, ALT, γ-GTP in the experimental group was lower than that of the control group. There were significant differences between two groups in the percentage of 'irregularity of diet' and in health behavior compliance. There were significant differences between the two groups in the number of complaints of symptoms after using the program. Conclusion: This study shows that there were no obvious differences between the two groups in all areas, but this program had a positive effect on health behavior changes. It is expected that employees' lifestyles can be changed through continuous health promotion programs.
