This study was conducted to investigate effects of dietary anthocyanin fortified barley (AFB) or whole crop barley (WCB) on growing performance, meat quality and blood properties in swine at late fattening phase. Swine performance was not significantly differed (p>0.05) but average daily gain and average daily feed intake tended to increase in treatments. Meat quality parameters including pH, cooking loss, shear force and meat surface color were not influenced by the addition of barley in diet. However, DPPH content of longgissmus dorsi muscle was significantly increased in WCB10 compared to control, AFB5 and WCB5 (p<0.05). FRAP content of longgissmus dorsi muslce was higher in WCB5 than the AFB (p<0.05), thereby, a tendency in FRAP was not similar to that of DPPH. Only myristic acid (C14:0) was affected, and the lowest myristic acid was found when AFB was supplied to swine. A tendency was not determined in total protein and HDL-cholesterol content, however, control, WCB10 and AFB5 had high in total protein and showed significantly low values in HDL-cholesterol. Therefore, the results indicate that barley can be considered as an ingredient in swine diet, but further investigation is necessary.

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.

This study was designed to find out the effects of aerobic exercise on lipid and Ca metabolism in seven healthy college women, aged 20 to 22 years. Metabolic studies were conducted before and after a 10-weeks exercise period, during which subjects participated in the planned aerobic dance program every day except Sunday. The initial mean time engaged in the exercise was 28 minutes and it was gradually increased up to 45 minutes around the middle point of the exercise period. During both of metabolic study periods, the subjects ate experimental diets which supplied about 120g of protein and 600mg of Ca daily and during the rest of the experimental period they ate their usual diets. The use of alcoholic beverages and drugs were prohibited. The results were summarized as follows. 1) The effect of exercise on lipid metabolism. (1) Mean body weight decreased significantly after exercise(p<0.01) and it did not show a significant decline in skinfold thickness and total body fat contents. (2) Serum total cholesterol level decreased significantly after exercise(p<0.05) and TG level also tended to be lower than that of pre-exercise period. Exercise did not exert any influence on the level of serum HDL-cholesterol in this study. (3) Exercise did not alter total lipid content in feces and apparent lipid absorption rate. 2) The effect of exercise on Ca and P metabolism. (1) After exercise, focal Ca excretion was slightly reduced, however, urinary Ca excretion was not significantly changed. In the results, a slight increase was shown in body Ca retention after exercise. (2) Exercise tended to increase urinary P excretion, but neither P balance nor fecal excretion was significantly changed after exercise. (3) Bone mineral content was not affected by exercise. In summary, aerobic exercise decreased total cholesterol and TG level in serum and tended to increase body Ca retention. With the results, it can be concluded that the additional physical activities beyond the normal daily life in college women might prevent some degenerative diseases-suchas atherosclerosis and osteoporosis.

This study was conducted to investigate the effects of feeding dried leftover food (DLF) on growth, body composition and feed conversion of broiler chicks. One hundred ninety-six of one-day old Ross broiler chicks were assigned to 7 treatments in a completely randomized design. Each treatment had four replications with seven chicks per replication. The treatments groups included control without DLF, dietary 10% level of DLF, dietary 20% level of DLF and dietary 30% level of DLF, 5% higher protein level of diet containing 10% DLF, 10% higher protein level of diet containing 20% DLF and 15% higher protein level of diet containing 30% DLF than control diet. Body weight gain was slightly higher in control group than that of DLF-fed groups. However, there were no significant differences in body weight gain among those groups fed diets containing different levels of DLF. In general, increasing dietary level of DLF resulted in decreasing feed conversion. Content of crude protein in whole broiler body was slightly higher in control group although any significant difference was not found among treatments (p>0.05). Content of crude fat in whole broiler body was lowest in groups fed diets containing 30% DLF with 15% higher protein level than control diet, showing significant difference from groups fed diets containing 20% DLF (p<0.05). Contents of total cholesterol, free cholesterol, cholesterol ester and LDL- cholesterol in blood of broilers fed DLF-containing diets generally appeared to be higher compared with control group without significant difference (p>0.05). Fatty acid contents in broiler meat were higher in the order of oleic acid, palmitic acid and linoleic acid without significant differences among treatments. Content of DHA in broiler meat was higher in groups fed diets containing DLF than that of control group although there were no significant differences among treatments (p>0.05).

In this study, we determined the effect of the mulberry leaf powder on blood lipid metabolism and liver function improvement of mice fed a high fat diet. The mulberry leaf showed a moisture content of $10.74{\pm}0.56%$, ash $9.67{\pm}0.56%$, crude protein $25.24{\pm}1.02%$, and crude fat $2.66{\pm}0.08%$. In the group with high fat diet supplemented with mulberry leaf powder, serum low-density lipoprotein (LDL-cholesterol) and total cholesterol levels were significantly lower (p<0.05); also, serum phospholipid and aspartate amino transferase (AST) levels were significantly lower (p<0.05). Serum insulin and leptin levels were high in mice fed a high fat diet; however, addition of mulberry leaf powder 10% in the diet had no significant effect on blood insulin and leptin control. The results of the study suggested that various plant sterols in mulberry leaf improve lipid metabolism and liver function in ICR-mice.

흑마늘의 구속 스트레스에 대한 유효농도를 확인하고자 2, 7 및 14 brix로 조절한 흑마늘 추출물을 급이한 흰쥐의 체내 지질대사를 중심으로 분석하였다. 흑마늘 추출물 14 brix 급이군의 식이섭취량은 $547.64{\pm}13.99$ g/4 weeks로 대조군에 비해 유의적으로 높았다. 모든 장기에서 흑마늘 추출물의 첨가 급이에 따른 무게의 변화는 통계적인 유의차는 없었다. 흑마늘 추출물 첨가 급이군의 혈당은 흑마늘 추출물의 농도가 높아질수록 낮아지는 경향을 보여 2 brix 추출물 급이군의 혈당은 $142.97{\pm}6.51$ mg/dl 였으나 14 brix 급이군에서는 $121.32{\pm}3.50$ mg/dl로 정상군 보다도 더 낮았다. 총 콜레스테롤 함량은 $54.54{\pm}1.63{\sim}65.84{\pm}2.61$ mg/dl의 범위였는데, 14 brix의 흑마늘 추출물 첨가 급이군의 혈청 총 콜레스테롤 농도는 $54.54{\pm}1.63$ mg/dl로 가장 낮은 함량이었으며, 정상군에 비해서도 유의적으로 낮은 함량이었다. 중성지질의 함량도 동일한 경향이었다. HDL-콜레스테롤 농도는 구속대조군에 비해 흑마늘 추출물 7 및 14 brix 급이군에서 유의적으로 높았으며, LDL VLDL-콜레스테롤은 이와 상반되는 결과를 나타내었다. 혈청 GOT 및 GTP 활성도는 흑마늘 추출물의 농도가 높아질수록 낮아져 흑마늘 추출물의 급이는 간보호 활성을 나타낼 것으로 기대된다. 간장내 총 지질 및 중성지질의 함량은 구속대조군에 비해 흑마늘 추출물 급이군에서 유의적으로 낮았으나 총콜레스테롤은 서로간에 유의차가 없었다. 간장내 지질 과산화물인 TBARS 함량은 2 brix의 흑마늘 추출물 급이군은 구속대조군과 유의적인 차이가 없었으나 7 및 14 brix 급이군은 정상군보다 더 낮은 함량이었다. 간장내 글리코겐 함량은 구속대조군에 비해 14 brix 흑마늘 추출물 급이군에서만 유의적으로 낮았다. 이상의 결과들을 종합하여 볼 때 7 brix 이상의 흑마늘 추출물 급이는 흰쥐의 지질대사를 개선하고, 간보호 활성을 나타냄으로써 구속 스트레스로 해소에 기여할 것으로 추정된다.

The present study was undertaken to determine the metabolic effect of various levels and kinds of fat in the diet. Body lipid metabolism at different period of rat's life was also studied by sacrificing rats and collecting samples initially, at second and fourth week of experimental period. Body weight, FER, PER were low in the group fed 30% fat diet. The weight of internal organ and epididymal fat pad was low in high fat diet group. The level of total serum cholesterol of rats in butter group showed higher than that of soybean oil group when the level of dietary fat content was same. The ratio of total cholesterol and total lipid in serum of rats in butter group appear to be higher than that of soybean oil group.

To investigate the effects of crude protein and thyroxine on growth performance, nutrient utilizability, carcass composition, the content of total fat and cholesterol in leg muscle, breast muscle and liver, and caloric efficiency in broiler chicks. The experiment involved 3 levels of dietary crude protein (1-3 weeks: 20, 23, 26%; 4-6 weeks: 17, 20, 23%) and 3 levels of thyroxine (0.0, 1.5, 3.0 mg/kg). In the starting period (1-3 weeks), body weight gain of chicks fed diets containing 26% crude protein and 1.5 mg/kg thyroxine was higher than any other groups, and among thyroxine levels, 3.0 mg/kg thyroxine groups were lower. The best feed efficiency was obtained at 26% crude protein with no thyroxine supplemented or 1.5 mg/kg thyroxine supplemented groups. In the finishing period (4-6 weeks) the highest body weight gain was obtained at 23% crude protein with no thyroxine supplemented group. Feed intake of 17% crude protein with 1.5 mg/kg thyroxine supplemented group was higher than those of the other groups. It was found that the utilizability of crude protein in the starting period, showed the best utilizability at 20% crude protein with 1.5 mg/kg thyroxine group. Increasing crude protein level from 17 to 23%, utilizability of crude fat was decreased. The carcass composition was significantly (p<0.05) influenced by crude protein and thyroxine. Increasing thyroxine level from 0.0 to 3.0 mg/kg, crude protein content was increased whereas, crude fat content was decreased. Chicks fed diet containing 1.5 mg/kg thyroxine showed the lowest total fat content in liver tissue. In breast muscle, it was significantly (p<0.05) affected by crude protein and thyroxine. Present data revealed that the cholesterol content was increased for the chicks fed 3.0 mg/kg thyroxine. It the caloric efficiency, chicks fed a diet containing 20% crude protein with no thyroxine supplementation showed the highest caloric efficiency and the lowest efficiency was from 23% crude protein group with 1.5 mg/kg thyroxine. From this study it may be concluded that crude fat content of carcass could be successfully reduced by dietary supplementation of thyroxine, whereas crude protein content was increased.

This study examined the antidiabetic and antihyperlipidemic activities of an ascidian (Halocynthia roretzi) in rats in vivo. Rats were fed on experimental diet including dried ascidian powder (200 mg/kg body weight) for 4 weeks, and then the triglyceride and total cholesterol levels in blood were analyzed. On the ascidian tunic powder diet, the triglyceride level decreased by more than 20.9% and the total cholesterol content decreased by more than 24.4%. In comparison, the triglyceride and total cholesterol level in the blood of rats fed ascidian meat powder decreased only slightly. Therefore, the ascidian tunic powder might be a healthy food with antidiabetic and antihyperlipidemic effects.
