The study was conducted to evaluate the effect of lighting schedule and nutrient density on growth performance, carcass traits and meat quality of broiler chickens. A total of 576 day old Arbor Acre male chickens was used with a $4{\times}2$ factorial arrangement. The four lighting schedules were continuous (23 L:1 D, CL), 20 L:4 D (12 L:2 D:8 L:2 D), 16 L:8 D (12 L:3 D:2 L:3 D: 2 L:2 D) and 12 L:12 D (9 L:3 D:1 L:3 D:1 L:3 D:1 L:3 D) and provided by incandescent bulbs. The two nutrient densities were high (H, starter diet: 13.39 MJ/kg apparent metabolisable energy (AME), 23.00% crude protein (CP); finisher diet: 13.39 MJ AME/kg, 19.70% CP) and low energy and protein level (L, starter diet: 12.03 MJ AME/kg, 20.80% CP; finisher diet: 12.14 MJ AME/kg, 18.30% CP). Houses with dark curtains and solid sidewalls were used. Chickens were randomly allocated to the 8 treatments with each treatment comprising 6 replicates of 12 chickens. Feed and water were available ad libitum. Lighting schedules showed no difference (p>0.05) in growth performance at the end of the experiment. 12 L:12 D significantly reduced (p<0.05) the concentration of malondialdehyde (MDA) compared to 23 L:1 D treatment. Intermittent lighting (IL) schedules produced higher protein content (p<0.001) in breast meat. Birds on high density diets had higher body weight (BW), feed intake (FI) (p<0.001), and feed conversion ratio (FCR) (p<0.001) throughout the experiment with the exception of 36 to 42 d. High nutrient density increased (p<0.05) abdominal fat, decreased (p<0.05) the moisture loss of meat, and reduced percentage of wings and legs. There was a significant lighting schedule${\times}$diet interaction (p<0.001) on FCR for days 8 to 14 and 15 to 21. Results indicated that IL can give similar growth performance in comparison with CL, meanwhile with positive effects on meat quality by increasing protein content and decreasing the concentration of MDA. High nutrient density resulted in greater growth performance.

This study investigated the anthropometric and biochemical indices, and the health and nutritional factors influencing the two indices among 194 middle-aged and elderly subjects (108 middle-aged and 86 elderly) residing in a medium sized city for more than 10 years. In the examination of their dietary habits, 8.3% of the middle-aged subjects and 14.0% of the elderly subjects had two meals a day, and more female subjects had two meals per day. Of the subjects who ate meals at regular times, 75.0% were middle-aged and 79.1% were elderly, and the degree of irregularity of meals was greater for female subjects. The study of the dietary behavior of the subjects indicated that 71.3% and 66.3% of the middle-aged and elderly, respectively responded that the amount of food in each meal was sufficient. The subjects ate alone comprised 19.7% of the middle-aged females and 31.5% of the elderly females. The prevalence of smoking among the subjects was 28.1% for the middle-aged, 18.8% for the elderly male and 7.4% for the elderly females. The percentage of the subjects who drank alcohol was 34.4% of the middle-aged males and 13.2% of the middle-aged females. Slightly less than half of the subjects exercised more than once a week, with the male subjects showing a higher rate than the female subjects. The average body mass indices (BMI) were 24.5 and 24.6 for the middle-aged male and female, respectively, and 22.6 and 24.0 for the elderly male and female, respectively. BMI assessment showed that underweight subjects (BMI ＜ 20) comprised 3.7% of the middle-aged, 14.0% of the elderly, and that 40.7% of the middle-aged and 24.4% of the elderly were overweight (25 ＜ BMI ＜ 30) , and 0.9% of the middle-aged and 1.2% of the elderly were classified as obese (BMI $\geq$ 30) . A waist/hip ratio (WHR) greater than 0.8 was found in 89.5% of the middle-aged females and 90.7% of the elderly females, showing high abdominal fat deposition in the majority of females. The average systolic blood pressure of females was 121.1 $\pm$ 17.1 mmHg for the middle-aged and 129.6 $\pm$ 21.3 mmHg for the elderly subjects. The systolic blood pressures showed a significantly difference between the two age groups. Those defined as anemic subjects based on hemoglobin values comprised 13.0% of the middled-aged group and 16.3% of the elderly group. There was a tendency for higher fasting glucose levels among the elderly subjects. An increase in total plasma cholesterol levels with age was shown. The female subjects had higher cholesterol levels than the males'The study of the correlation between the daily habits and health status showed that the amount of food eaten at each meal, the frequency of eating out, and the use of dietary supplements appeared to influence BMI, WHR, the plasma triglyceride and plasma cholesterol levels; omitting one meal had a positive correlation with the systolic blood pressure and plasma cholesterol. These results suggest that desirable dietary habits and concerns for health are contributing factors for maintaining good health, as indicated by normal blood lipid levels.

This study was conducted to investigate the effect of dietary green tea extract (GTE) on the performance, carcass and gastrointestinal tract (gut) traits, caecal coliform bacteria count, and pH and color (CIE $L^*$, $a^*$, and $b^*$) values of the breast muscle in broilers. A total number of 600 day-old broilers (Ross 308) was allocated to three treatments with four replicates containing 50 (25 males and 25 females) birds. The dietary treatments consisted of the basal diet as the control (0GTE) and diets with GTE at 0.1 (0.1GTE) or 0.2 (0.2GTE) g/kg. Body weights and the feed intake of broilers were measured at 1, 21 and 42 days, the feed intake was measured for different periods and the feed conversion ratio was calculated accordingly. At 42 day four birds per replicate were slaughtered for the determination of carcass and organ weights, caecal coliform bacteria count, and also quality of the breast muscle. The dietary GTE increased the body weight, feed efficiency, carcass weight and dressing percentage and decreased caecal coliform bacteria count of broilers (p<0.05). The 0GTE broilers consumed (p<0.01) less feed than the 0.1GTE birds in the entire experimental period. The relative abdominal fat weight and gut length of broilers in the 0.2GTE were tended to be lower (p<0.07) than those in the 0GTE group. The breast meat from 0.1GTE birds had a lower pH value when compared to that from 0GTE birds. The 0.1GTE broilers had lighter breast meat than 0GTE and 0.2GTE birds. The dietary GTE increased $a^*$ and $b^*$ values of the breast meat. Thus this product appeared to have a measurable impact on CIE color values of the breast meat in broilers. The results of the present study may indicate that the improved production results in the group with added GTE are directly connected with physiological mechanisms such as the regulation of the caecal micro-flora.

Two experiments were conducted to investigate the feeding influence of wood vinegar and mixed with probiotics on performance and physiological related of broiler chicks for five weeks. Diets contained 21.5%, 3,100kcal/kg and 19.0% CP, 3,100kcal/kg ME for starting and finishing period, respectively. In Expt 1, Four levels of wood vinegar(0, 0.05, 0.10, 0.20%) were fed into two hundred forty chicks with four replicates. In Expt 2, 0, 0.1% wood vinegar(W), 0, 0.1% lactobacillus casei(L) and bacillus subtilis (B) were applied to 2${\times}$2${\times}$2 facotrial design for eight treatments with four replicates. Weight gain, feed intake, feed cholesterol were detected at five weeks old in each experiment. In Expt 1, Weight gain of chicks fed 0.1% wood vinegar(WV) was increased upto 1645.8g, but was not significantly different. However, chicks fed 0.2% WV showed the highest gain and siginificantly different compared to that of control (P＜0.05) for finishing period. Feed intake also showed similar tendency with weight gain. There were no statistical difference in feed conversion. Abdominal fat seemed to be decreased in WV supplemental groups, whereas ND antibody titer tended to increase in those treatments. In Expt 2, 0, 0.1% WV, lactobacillus, bacillus were combined with each other(W$\sub$0/L$\sub$0/B$\sub$0/, W$\sub$0/L$\sub$1/B$\sub$0/, W$\sub$0/L$\sub$0/B$\sub$1/, W$\sub$0/L$\sub$1/B$\sub$1/, W$\sub$1/L$\sub$0/B$\sub$0/, W$\sub$1/L$\sub$1/B$\sub$0/, W$\sub$1/L$\sub$1/ B$\sub$0/, W$\sub$1/L$\sub$0/B$\sub$1/, W$\sub$1/L$\sub$1/B$\sub$1). WV supplemental groups significantly improved feed conversion of all treatments(P＜0.05). There were no interaction in weight gain and feed intake. Total cholesterol was signficantly decreased in WV plus lactobacillus and ladtobacillus plus bacillus treatments. Liver to body ratio(%) of lactobacillus plus WV significantly decreased compared to that of other treatments. The results of these experiments showed that wood vinegar tended to improve the performance of broiler chicks, but was not effect in its combination with lactobacillus or bacillus treatments.

This study investigated the functional effect by diets of Triticum aestivum sprout (TA) on the levels of blood glucose and lipid profiles in streptozotocin(STZ)-induced diabetic mice. Diabetes mellitus were induced by STZ intraperitoneal injection (50 mg/kg) into the male Balb/c mice. All mice fed AIN-93 diet for 3 weeks. Mice were divided to 4 groups: normal, diabetic control and two experimental groups (TA 5.0, diet with Triticum aestivum sprout 5.0% w/w; TA 2.5, diet with Triticum aestivum 2.5% w/w). The blood glucose level was decreased by TA intake in diabetic mice in the dose-dependant manner; 21.34% and 35.77% in TA 2.5 and TA 5.0 groups. The weight gain and feed efficiency ratio also were improved by TA intake compared with DM group. The weight gain was increased 1.28 and 1.09 folds in TA 5.0 and TA 2.5 groups, respectively. The weight of organs, including liver and kidney, was reduced but that of spleen and abdominal fat was increased by TA intake. Moreover, TA treatment increased the level of HDL but decreased the level of total cholesterol and triglycerides in the blood of diabetic mice. The blood of HbA1c also was significantly decreased without changing hematocrit by TA treatment compared with DM group. These results indicate the TA intake has the functional effects attenuating blood glucose and plasma lipid levels in insulin-dependent diabetes.

본 연구는 대학 엘리트 카나디언 선수들의 등속성 근기능을 검사 및 진단하여 선수들의 기능 향상 및 상해예방을 위한 훈련 방법론에 대한 조언을 하고자 함에 목적이 있다. 경주 소재 D 대학의 평균 8.5년의 경력을 가진 8명의 엘리트 선수들이 실험에 참가했으며, Biodex system III, Biodex stabilizer system, THP 2, Inbody 720이 근기능 검사(peak torque, average power, work fatigue), 동적 균형 검사, 신체성분 검사를 위해 사용되었다. 등속성 근기능 검사는 어깨와 허리, 무릎 관절에 대하여 실시하였으며, 측정 후 동측 불균형과 좌 우측 불균형 정도를 평가하였다. 검사 결과 A3, A4, A5, A6, A8 선수는 어깨의 근력과 파워 훈련이, A1, A2, A7, A8 선수는 어깨의 근지구력 훈련이 필요한 것으로 평가되었다. A2, A5, A8 선수는 허리의 근력과 파워 강화 훈련이 필요하였고, A1, A8 선수는 허리의 근지구력 강화 훈련이 필요하였다. 대부분의 선수들은 무릎과 허리의 동측 근력비가 정상적이지 못했는데, 이의 개선을 위해 A2, A3, A4, A8 선수는 복근의 강화가 필요했고 A3, A5, A6, A7, A8 선수는 햄스트링의 강화가 요구되었다. 선수들의 BMI 평균은 24.90 $kg/m^2$, 체지방율은 12.23%, 반응시간 평균은 324 msec, 밸런스 점수는 각각 2.0 미만으로 나타났다. 이러한 결과를 종합해 볼 때, 카나디언 엘리트 선수들은 근력 불균형에 의한 경기력 저하와 상해 잠재 위험성이 있으므로 정기적인 근기능 검사를 통한 관리와 함께 적절한 훈련 처방이 필요할 것이라 생각된다.

Objective: The study was conducted to evaluate the effect of stocking density and alphalipoic acid (ALA) on the growth performance, feed utilization, carcass traits, antioxidative ability and immune response of broilers. Methods: A total of 1,530 22-day-old male broilers (Arbor Acres) with comparable body weights ($731.92{\pm}5.26$) were placed into 18 cages ($2.46{\times}2.02m$) in groups of 75 birds ($15birds/m^2$, $37.5kg/m^2$; low stocking density [LD]), 90 birds ($18birds/m^2$, $45.0kg/m^2$; high stocking density [HD]) and 90 birds with 300 mg/kg ALA added to the basal diet ($18birds/m^2$, $45.0kg/m^2$; HD+ALA, high stocking density+${\alpha}$-lipoic acid); each treatment was represented by 6 replicates. The experimental period was 3 weeks. Results: The results showed that the high stocking density regimen resulted in a decreased growth, feed conversion ratio, carcass weight, thigh yield and bursa weight relative to body weight (p<0.05) on d 42. The abdominal fat yield in the HD+ALA group was lower (p = 0.031) than that of the LD group at 42 d. The superoxide dismutase and glutathione peroxidase activities in serum were increased, and malondialdehyde content decreased after adding ALA product (p<0.05) on d 42. Additionally, the serum concentrations of immunoglobulin A (IgA) and IgG were decreased (p<0.05) and the level of diamine oxidase was higher (p<0.01) in the HD group on d 42. Conclusion: The high stocking density significantly decreased broiler growth performance, feed utilization and carcass traits, increased physiological and oxidative stress and induced intestinal mucosal injury. The supplementation of ALA product in broiler diet at 300 mg/kg may reduce the adverse effects of high stocking density-mediated stress by maintaining the antioxidant system and humoral immune system.
