  • The current study was conducted to estimate the effect of dietary taurine on performance, egg quality, blood parameter, liver lipids and lipid peroxidation level of laying hens fed high fat diet. Two hundred eighty laying hens, forty five weeks of age, were allocated to four treatment groups with seven replicates of 10 each per treatment for 4 weeks. Experimental diets were assigned to each of the four groups: control diet (CON), CON with 0.5% taurine (CT), CON with 5% soybean oil (HF), and CON with 5% soybean oil and 0.5% taurine (HFT). Egg weight was significantly lower in the control than the CT (P<0.05). However, the HFT was similar to the level compared to both control and HF. Serum concentrations of total cholesterol, triglyceride and glutamic oxaloacetic transaminase (GOT) were significantly decreased by about 30%, 36% and 20%, respectively in the HFT compared to the HF (P<0.05). In the liver tissue, triglyceride concentration tended to be lower by about 28% in the HFT compared to the HF (P<0.05). The hepatic lipid peroxidation level was significantly decreased by about 25% in the HFT compared to the HF (P<0.05). These results indicated that taurine supplementation improved the serum total cholesterol, triglyceride concentration, and decreased hepatic lipid peroxidation level without affecting performance in laying hens fed high fat diet.

  • Three different diet were made with meat for Crossbred pig ($^{\circ}_{+}$, 195 days old, $l15{\pm}5\;kg,\;Landrace{\times}Yorkshire{\times}Duroc$) and used as feed for rats after transformed into 12% protein, These diets include a pork not fed with tangerine peel during finishing period (Control, $T_0$), a pork fed with 3 and 5% tangerine peel during growing and finishing period, respectively ($T_1$), and a pork fed with 6 and 10% tangerine peel during growing and finishing period respectively($T_2$). The effects of the diet on physiological activities of rats were studied by feeding 17 weeks-old Sprague-Dawley rats with the three diets for 4 weeks. The feed intake, weight gain, feed efficiency ratio, and weight of liver, kidney, spleen and epididymal fat pad for the rats was similar among the diets. The total lipid level of liver was similar among $T_0,\;T_1\;and\;T_2$. However, it was found that $T_1\;and\;T_2$ had significantly lower triglyceride and cholesterol level than $T_0$(p<0.05). All the diet groups showed similar trends in terms of the serum total lipid, phospholipid, triglyceride, total cholesterol, HDL-cholesterol and LDL-cholesterol level, and atherogenic index, hemoglobin level, and ${\gamma}-GTP$, ALT, AST and ALP activities.

  • This study was carried out to investigate the effect of diet (1:1 ratio) added with meat product (seasoning chicken product, patty) containing natural extracts (green tea, Schizandra chinensis) on body weights, internal organs weights, the contents of total cholesterol, HDL-cholesterol, triglyceride and total lipid in plasma and liver. The experimental diets were prepared with basal diet added with $1\%$ natural extracts. These diets were supplied to SD (Sprague-Dawley) rats for 45 days. The body weight of SD rats supplied seasoning chicken and patty containing green tea and Schizandra chinensis tended to be lower than that of SD rats dieted seasoning chicken product and patty product. The contents of plasma cholesterol, HDL-cholesterol, triglyceride and total lipid were decreased in SD rats dieted seasoning chicken and patty with green tea and Schizandra chinensis. However, the contents of plasma cholesterol, HDL-cholesterol, triglyceride and total lipid tended to be increased in SD rats supplied seasoning chicken product and patty only. Hepatic lipid peroxidation measured by TBARS method was not different, compared to that of control. In conclusion, the diets with meat products containing $1\%$ natural extracts were effective in reducing plasma and hepatic cholesterol levels in rats.

  • The effects of different dietary lipids on growth, body chemical composition, and nutrient partition of the Korean rockfish (43 g of initial mean weight) were studied. Fish were fed three experimental diets containing 1) $4.5\%$ squid liver oil, 2) $1\%$ squid liver oil and $3.5\%$ beef tallow, and 3) $1\%$ squid liver oil and $3.5\%$ soybean oil. Growth and feed efficiency were detarmined during a 19-week feeding period at water temperature of $15.5^{\circ}C$, and at the end of which body chemical compositions were analyzed. Remained fish were fasted for 45 days, and four fish were taken at 6, 12 and 24 hours, and 3, 15 and 45 days after the fasting to determine tissue compositions and hematological changes. Growth, feed efficiency, protein and lipid retention efficiency, hepatosomatic index(HSI), viscerosomatic index (VSI), and chemical composition of whole body and dorsal muscle were not affected by the different dietary lipids. Liver moisture content of fish fed squid liver oil diet was higher than that of fish fed beef tallow or soybean oil diet. Liver lipid content of fish fed beef tallow diet was higher than that of fish fed the other diets. Fatty acid composition of dorsal muscle and liver were affected by the different dietary lipids ; high levels of 20 : 5n-3 and 22 : 6n-3 from fish fed the diet containing squid liver oil, 18 : 1 from fish fed the diet containing beef tallow, and high 18 : 2n-6 and 18 : 3n-3 from fish fed the diet containing soybean oil were observed. Both HSI and VSI of fish fed three diets decreased with time after the begining of starvation. Liver glycogen did not change during the first 15 days of starvation and decreased thereafter, and that was not affected by the different dietary lipids. Lipid and protein contents in the dorsal muscle of fish decreased up to 15 days of starvation and remained unchanged thereafter, these were not different from each other. Glucose, free fatty acid, triglyceride and phospholipid concentrations in Fish serum were varied for the first 15 days of starvation, after that the concentrations of fish serum remained relatively stable in all the treatment groups with prolonged starvation. The results indicate that Korean rockfish can utilize fish oil, animal fat or vegetable oil equally as energy source when n-3HUF A is adquate.

  • The effect of feeding a cyclic oligosaccharide, $\beta$-cyclodextrin($\beta$CD) on plasma cholesterol and triacylglyceride concentrations and on antithrombotic activity were investigated in rats fed a control chow diet, or one either high in cholesterol or in saturated fat. The bleeding time of $\beta$CD-fed groups was significantly prolonged by 293%, 157% and 218% in normal, high cholesterol and high fat diet fed groups, respectively, as compared to the control group(p<0.05). The whole blood clotting time was significantly increased by 202%, 168% and 211% in normal, high cholesterol and high fat diet fed groups as compared to control group, respectively(p<0.05). The $\beta$CD diet caused a marked decrease in plasma total lipid(TL), triacylglyceride(TAG), total cholesterol (TC) and low density lipoprotein- cholesterol (LDL-C) concentrations. The plasma TL concentration was significantly decreased by 70%, 82% and 87% in normal, high cholesterol and high fat diet fed groups as compared to the control group, respectively(p<0.05). The plasma TAG concentration was significantly decreased by 89%, 43% and 59% in normal, high cholesterol and high fat diet fed groups, respectively, as compared to the control group(p<0.05). The plasma TC concentration was significantly decreased by 28%, 62% and 36% in normal, high cholesterol and high fat diet fed groups, respectively, as compared to the control group(p<0.05). The LDL-C concentration was significantly decreased by 39%, 54% and 25% in normal, high cholesterol and high fat diet fed groups as compared to control group, respectively(p<0.05). The plasma total bile acids contents of $\beta$CD group was significantly increased by 66%, 95% and 97% in normal, high cholesterol and high fat diet fed groups as compared to control group, respectively(p<0.05). The hepatic HMG-CoA reductase activity was significantly lowered by 41% in the $\beta$CD-fed group compared to normal diet fed rats(p<0.05). The fecal steroid excretions of the $\beta$CD groups was significantly increased by 167% in normal diet fed rats(p<0.05). These results suggest that the $\beta$CD has a biological active function on antithrombotic activity and is hypolipidemic, hypotriglyceridemic and hypocholesterolimic agents. These are all effects that can help to prevent obesity and coronary heart disease in humans.
