Forty-eight crossbred heifers ($378.1{\pm}18$ kg) were used in a 56-d feeding trial (four pens per treatment in a randomised complete block design) to evaluate the influence of ionophore supplementation on growth performance, dietary energetics and carcass characteristics in finishing cattle during a period of heat stress. Heifers were fed a diet based on steam-flaked corn (2.22 Mcal $NE_m/kg$) with and without an ionophore. Treatments were: i) control, no ionophore; ii) 30 mg/kg monensin sodium (RUM30); iii) 20 mg/kg lasalocid sodium (BOV20), and iv) 30 mg/kg lasalocid sodium (BOV30). Both dry matter intake (DMI) and climatic variables were measured daily and the temperature humidity index (THI) was estimated. The maximum THI during the study averaged 93, while the minimum was 70 (THI average = $79.2{\pm}2.3$). Compared to controls, monensin supplementation did not influence average daily gain, the estimated NE value of the diet, or observed-to-expected DMI, but tended (p = 0.07) to increase (4.8%) gain to feed. Compared to controls, the group fed BOV30 increased ($p{\leq}0.03$) daily gain (11.8%), gain to feed (8.3%), net energy of the diet (5%), and observed-to-expected DMI (5.2%). Daily weight gain was greater (7.6%, p = 0.05) for heifers fed BOV30 than for heifers fed MON30. Otherwise, differences between the two treatments in DMI, gain to feed, and dietary NE were not statistically significant (p>0.11). Plotting weekly intakes versus THI, observed intake of controls was greater (p<0.05) at THI values ${\leq}77$ than ionophore groups. When THI values were greater than 79, DMI of control and MON30 were not different (p = 0.42), although less than that of groups fed lasalocid (p = 0.04). Variation in energy intake was lower (p>0.05) in the ionophores group (CV = 1.7%) than in the control group (CV = 4.5%). Inclusion of ionophores in the diet resulted in relatively minor changes in carcass characteristics. It is concluded that ionophore supplementation did not exacerbate the decline of DM intake in heat-stressed cattle fed a high-energy finishing diet; on the contrary, it stabilised feed intake and favoured feed efficiency. Ionophore supplementation reduced estimated maintenance coefficients around 10% in finishing cattle during a period of heat stress. This effect was greatest for heifers supplemented with 30 mg lasalocid/kg of diet.

Objective: This study was performed to investigate the effects of supplementing sesame seed meal (SSM) with phytase and lysine on performance, egg quality, blood biochemical and antioxidant status of laying hens. Methods: A total of 960, 56-wk-old laying hens were divided into 12 dietary groups with eight replicates per group (10 birds per replicate). A completely randomized design with factorial arrangement 2×3×2 consisted of two levels of lysine supplement (0% and 10% over requirement), three SSM levels (0%, 10%, and 20%) with or without phytase (0 and 300 g/ton). The feeding trial lasted 10 weeks. Results: Birds fed diets with 10% SSM had higher feed intake than groups fed 0% and 20% SSM. The addition of phytase to experimental feeds, improved feed conversion ratio, increased egg weight and mass (p<0.01). Egg quality criteria was not affected by supplementing phytase; however, supplementing 300 g/ton phytase to hens diet, led to a significant (p<0.05) increase in egg shell strength. Egg yolk cholesterol and serum low-density lipoprotein cholesterol, atherogenic index and total cholesterol were decreased (p<0.01) by diet containing 20% SSM. The high-density lipoprotein cholesterol was increased (p<0.05) in serum of hens fed 20% SSM than the other groups. It was also observed that total antioxidant capacity and total superoxide dismutase content of hens fed 20% SSM was significantly higher than control group (p<0.05). Conclusion: As from results, dietary supplementation of SSM and phytase had no negative effects on laying hens performance or egg quality while improving the egg oxidative stability.

Ssireum, the traditional Korean sport, is very popular at both amateur and professional levels. Ssireum players are prone to be obese which related to the chronic disease in their later life. The purpose of the study was to compare the anthropometric measurements, quality of diet, and blood parameters of Ssireum players with those of subjects who were matched body mass index, gender and age. Participants in the 3 groups, Ssireum players (SP, n=15), regular moderate exerciser (RME, n=15, >3 times /wk, >20 min/time) and intermittent light exerciser (ILE, n=14) groups. Anthropometric measurements included height, weight, fat mass (by Dual energy X-ray absorptiometry), lean body mass, triceps and thigh skin-fold thickness, mid-arm, waist, hip and thigh circumference. Dietary assessments were accomplished using 3-days food records, diet quality index (DQI), dietary variety score (DVS). Blood levels of lipids, leptin and insulin were analyzed. As a results lean body mass and mid-arm circumference were significantly higher in Ssireum players than those of other groups (p<0.01). Total body fat, trunk fat, abdominal skin fold thickness and waist-hip ratio were significantly lower in SP group than those of other groups (p<0.01). DVS were higher however, dietary quality was low in Ssireum players than in other groups. There were no differences among the 3 groups in regard to blood total cholesterol, LDL-cholesterol and glucose levels however, leptin level was low in Ssireum players. These results indicate that Ssireum players had significantly higher lean body mess and lower body fat when these were compared with regular moderate exerciser and intermittent light exerciser. Blood leptin levels of Ssireum players were low but blood lipid profiles were not significantly different.

The gossypol existed in cottonseed meal is a well known antispermatogenic agent which can impair reproductive performances of male fish as well as mammals. Two feeding experiments were conducted to examine a toxic effect of dietary supplementation of cottonseed meal on reproduction in juvenile olive flounder (the first experiment) for 19 weeks and growing olive flounder (the second experiment) for 26 weeks. After each feeding study, females and males were sampled for histological examination in gonads and liver to verify any negative effects by the dietary supplementation of cottonseed and soybean meal on reproduction. After two feeding trial, the gonad somatic index (GSI) of male and female (from the first feeding trial) were not significantly different among all the dietary treatments. The GSI values of female (from the second feeding trial) were not significantly different among all the dietary treatments. However, males fed cottonseed and soybean meal containing diets exhibited significantly lower GSI than that fed the control diet after the second feeding trial. Histological examination of gonads and liver of fish fed cottonseed and soybean meal did not show any negative effects compared to those of fish ffd the control diet. Hepatosomatic index of fish in the first and second feeding trials were not significantly different among all the dietary treatments. The findings in this study suggest that dietary supplementation of cottonseed and soybean meal up to 40% fish meal replacement might not deteriorate the gametogenesis of juvenile and growing olive flounder. However, the supplementation in diets over 30% fish meal replacement might reduce GSI of male in growing olive flounder.

Atopic dermatitis (AD) is believed to be associated with the intake of antioxidant nutrients and fatty acids due to its immunological dysfunction. The purpose of this study was to examine the effects of nutrition education promoting vegetable, fruit, and fish intake on the severity of AD in children. Children with AD aged 6 months to 5 years were randomly assigned into education and control groups, and followed for 1 year. Seventy-six children completed the study (38 for control, 38 for education). The education group received education promoting the intakes of antioxidant-rich foods (vegetables, fruits) and n-3 fatty acid foods (fish). A 24-hour food recall was collected for the diet information. After education, all vegetables (p < 0.001), fruits (p < 0.01), and fish (p < 0.05) intakes per 1000 kcal increased significantly in the education group, whereas only vegetable intake increased in the control group (p < 0.001). The SCORAD index, the severity of atopic dermatitis, decreased significantly in the education group (p < 0.05). Increased consumption of dietary vitamin E was significantly associated with reduction in the SCORAD index, after adjusting for age and gender (p < 0.05). A nutritional education program to increase vegetable, fruit, and fish intake may be effective in reducing the severity of AD, and vitamin E intake may be associated with the decreased severity of AD. More controlled studies on the relationship between these intakes and severity of AD, with intensive diet and/or supplement intervention programs, are needed to obtain conclusive results.

본 연구는 모시잎의 혈청, 간 및 지방조직의 체내 지질대사 개선 및 항비만 효과를 살펴보기 위하여 in vivo에서 5주령 된 흰쥐 수컷 24마리를 1주일간 적응시킨 후 정상 식이군(N), 고지방-고콜레스테롤 식이군(HFC), 고지방-고콜레스테롤 식이와 5% 모시잎 분말 첨가군(HFC-RL) 및 고지방-고콜레스테롤 식이와 10% 모시잎 분말 첨가군(HFC-RH)으로 나누어 4주간 실시하였다. 고지방-고콜레스테롤 식이로 인하여 체중이 유의적으로 증가하였으나, 모시잎 분말의 첨가 수준이 증가할수록 체중이 유의하게 감소하였다. 식이섭취량은 대조군(HFC)이 가장 낮았으며, 모시잎 분말 급여로 감소하는 경향이었다. 식이효율은 10% 모시잎 분말첨가로 유의하게 감소하여 정상 식이군(N)의 식이효율 수준과 유사하였다. 장간막지방조직과 부고환지방조직의 무게는 10% 모시잎 분말 첨가로 유의하게 감소하여 정상 식이군(N)보다 오히려 더 감소하는 경향을 보였다. 고지방-고콜레스테롤 식이로 증가되어진 혈청 중 AST, ALT, ALP 및 LDH 활성은 모시잎 분말 급여로 저하되었다. 혈청 중 중성지방 함량과 총콜레스테롤 함량도 고지방-고콜레스테롤 식이 급여로 증가되었으나, 모시잎 분말 첨가에 따라 농도 의존적으로 감소하였다. 고지방-고콜레스테롤 식이로 감소되어진 혈청 중 HDL-콜레스테롤 함량은 모시잎 분말 급여로 모두 유의하게 증가하였으며, 증가되어진 혈청 중 LDL-콜레스테롤 함량은 모두 유의하게 감소하였다. 동맥경화지수와 심혈관위험지수는 5%와 10%의 모시잎 분말 급여로 모두 유의하게 감소하였으며, 특히 10% 모시잎 분말을 급여하였을 경우 감소효과가 커 정상 식이군(N)과 유사한 경향이었다. 간조직 중 중성지방과 총콜레스테롤 함량은 모시잎 분말 급여로 모두 대조군(HFC)에 비하여 유의하게 감소하였다. 장간막지방조직과 부고환 지방조직의 중성지방 및 총콜레스테롤 함량도 모시잎 분말 급여로 유의하게 감소하였다. 지방조직의 HR-LPL과 TE-LPL 활성은 모시잎 분말의 첨가 급여로 농도 의존적으로 유의하게 감소하였다. 이상의 실험 결과 고지방-고콜레스테롤 식이와 함께 급여한 모시잎 분말은 체중, 간 및 지방조직의 무게 감소와 더불어 혈청 및 지방조직의 지질대사 개선에 긍정적인 영향을 미치는 것으로 나타났다. 이러한 결과는 모시잎 분말에 다량 함유된 식이섬유소와 클로로필 등의 생리활성 물질이 지질대사를 개선시키고 지방축적을 억제하여 고지혈증의 예방 및 치료효과와 비만을 억제하는 효과를 나타내 대사성 합병률과 심혈관계 질환의 발생을 감소시키는데 효과가 있을 것으로 생각되어진다. 그 외에 어떠한 생리활성 성분이 어떻게 작용을 하는지에 대해서는 추후 더 체계적인 연구가 필요할 것으로 사료된다.

본 연구는 다량의 당질과 단백질을 함유하고 있는 매생이가 동물의 체내 지질대사에 미치는 영향을 검토하였다. SD계 흰쥐를 기초식이군과 1% 콜레스테롤 급이군, 그리고 콜레스테롤과 동시에 5% 매생이를 급이한 매생이 급이군으로 나누어 5주간 급여하여 혈액과 간 중의 지방과 콜레스테롤 함량을 측정하고, 비만 유전자인 랩틴 단백질의 발현정도를 측정하였다. 혈청 중 중성지방과 총콜레스테롤 함량은 기초식이군에 비해 콜레스테롤 급이군에서 높게 나타났으며, 매생이 급이군은 콜레스테롤 급이군에 비해 유의하게 낮았다. 혈청 중 HDL-콜레스테롤 함량은 콜레스테롤 급이군에서 가장 낮게 나타났으나, 콜레스테롤과 함께 급이한 매생이 급이군에서는 높아지는 경향을 나타내었다. 간 중의 중성지방과 총콜레스테롤 함량 또한 콜레스테롤 급이군에 비해 매생이 급이군에서 유의적으로 낮은 경향을 나타내었다. 즉, 고콜레스테롤혈증이 유발된 흰쥐에 대한 매생이 급이가 다른 해조류와 마찬가지로 기능성 식이섬유로서 작용하여 혈청 및 간 내 콜레스테롤, 중성지질 및 LDL-콜레스테롤 농도의 저하, HDL-콜레스테롤 농도의 상승 및 동맥경화지수의 저하 등 지질개선 효과가 있는 것으로 확인되었다. 따라서, 동결건조하여 분말화시킨 매생이 자체만으로도 혈청 또는 간장에서의 지질개선 뿐만 아니라 심혈관계 질환의 치료를 목적으로 하는 식품소재로서의 활용이 가능할 것으로 생각된다.

This study investigated the effects of Gymnema sylvestre (GS) extract on body weight, adiposity, and lipid metabolism in leptin-deficient ob/ob mice. The experimental mice were divided into the following 4 groups: basal diet (AIN-93G diet) and 0.5%, 1%, and 1.5% GS supplemented groups. Each group was fed the experimental diet for 9 weeks. The final body weights, adipocyte sizes, and epididymal fat weights of the GS groups were significantly lower than those of the control group. There were no significant differences in food intake and food efficiency ratios among the treated groups. Serum triglyceride levels and the atherogenic index were significantly lower in the GS groups compared to the control group. Serum HDL cholesterol levels were significantly higher in the 1% and 1.5% GS groups compared to the control group. Serum glutamate oxaloacetate transaminase and glutamate pyruvate transaminase activities did not differ among the four experimental groups. The total hepatic lipid content was significantly lower in the GS groups, and hepatic cholesterol and triglyceride contents tended to be reduced in the GS groups compared to the control group. These results suggest that GS extract may be useful for ameliorating dyslipidemia and fatty liver.
