  • The laying performance of Japanese quails fed graded levels of high glucosinolate ($92.5{\mu}mole/g$) rapeseed meal (RSM) was assessed. One hundred and twenty Japanese quails aged 1 day-old were assigned at random to four dietary treatments consisting of 0, 50, 75 or 100 g/kg RSM in the diet replacing part of the soybean meal and de-oiled rice bran in a standard quail ration. 12 female representative quails from each diet were selected at random and housed in individual cages from 7-20 wk of age. The egg production, feed intake and FCR was comparable among the different dietary groups. The egg quality characteristics, organoleptic evaluation of boiled eggs as well as the haematological (haemoglobin, total erythrocyte count, total leucocyte count) and biochemical (glucose, protein, cholesterol, aspartate amino transferase, alanine amino transferase and alkaline phosphatase) constituents did not differ significantly among the groups. The gross and histopathological studies of vital organs did not reveal any appreciable changes. The feed cost was reduced by the incorporation of RSM in the diet, but only the production cost of quails fed the 75 g/kg RSM was lower in comparison to other groups. In the present study, the laying potential of Japanese quail was well-maintained up to the 100g/kg dietary level of rapeseed meal.

  • Freshwater softshell turtle (Trionyx sinensis) extract has been used traditionally as a tonic soup, and to recover from physical fatigue. To support these claims, the forelimb grip strength of mice was measured after feeding a soft-shell turtle extract for 7 days. The T. sinensis extract significantly increased the grip strength to $1.25{\pm}0.07N$ (P<0.01), which is 16.8% higher than the force on day 0. After exercising, the blood glucose levels in extract-fed mice were 202% higher and urea levels were 73% lower, which were both significantly different than the levels observed after control treatment. Lactate dehydrogenase was significantly higher by 314%, and glutathione peroxidase increased by 165%. In addition, the obesity markers, serum triglyceride and cholesterol, decreased to 62% and 49%, respectively, after mice were fed the extract. These data show that the T. sinensis extract provided more energy for forelimb exercise, prevented protein catabolism and muscle fatigue, and decreased the oxidative stress caused by an exhaustive workout.

  • Fifteen intact male Jamunapari goats, average body weight $22.0{\pm}1.18kg$ were divided into three groups of 5 animals in each to investigate the effects of feeding leucaena on energy retention and distribution of retained energy. Leucaena leaves and twigs provided 0%, 25% and 50% of CP in the rations of animals in $L_1$ (control), $L_2$ and $L_3$ groups, respectively. Energy balances were determined in an open circuit respiration chamber from gaseous exchange and nitrogen carbon balances. Energy retentions calculated from gaseous exchange data were 181.6, 190.0 and 172.8 kJ/kg $W^{0.75}/d$ and from carbon-nitrogen balances were 178.2, 199.5 and 171.1 kJ/kg $W^{0.75}/d$ in $L_1$, $L_2$ and $L_3$ groups, respectively. No significant difference was observed among the groups in both the methods. The retention of nitrogen and energy in the form of protein was similar in different treatment groups. Similarly, no significant effect was observed on energy retention in the form of fat and total energy retention due to incorporation of leucaena in the diets.

  • Human milk contains the nutrients for the growth and the development of the newborn. It contains specific proteins, lipids, and other components designed to be easily digestible and which play important roles in infant nutrition. However, when the lactation is failure or milk secretion is not enough, bovine milk based dried formulations, which is called infant formula, have been widely used for infant feeding. In this study, we investigated protein composition and amino acids profile related to easy digestion; fatty acids composition and LCPUFA(DHA and ARA) related to brain and eye development; synbiotics which take advantage of both probiotics and prebiotics; and colostrum-originated functional micronutrient as major issues in the recent infant formula. Domestic infant formulas, which are based on the research of human and bovine milk rich in functional components for immunity, growth, anti-allergenicity, digestion and brain development, have been developed to be similar to human milk.

  • The nutritional demand of oyster larva (Crassostrea gigas) were investigated to determine the optimal culture conditions and improve micro-algae utilization. Changes in nutrients and shell growth were examined in fed and 96-h (48 h in late umbone stage) oysters at four larval stages. Shell growth increased significantly in D shape larvae, regardless of feeding variations. No growth was observed in starved larvae, except in shell length of umbone (to 11.9 ${\mu}m$). Fed larvae showed significant growth in all development stages (P < 0.05). During starvation, lipids were most significantly decreased in all larval stages (by 76.8%, 68.3%, 76.3%, and 40.3%, respectively), followed by protein (41.1%, 31.1%, 33.1%, 16.7%) and nitrogen-free extracts (40.8%, 24.3%, 36.9%, 20.1%), Gross energy (kcal/g) consumption in each larval stage was 49.6%, 35.1%, 39.1%, and 20.4%, respectively. Our results indicate that lipids are the most important energy source during the early larval development stages of C. gigas.

  • The objective of this study was to investigate the biological activities of fermented mugworts and their effects on the lipid metabolism in hyperlipidemia-induced rats. The proximate compositions of two kinds of mugwort, Artemisia capillaris Thumberg and Artemisiae asiaticae Nakai, were compared before and after fermentation. In both types of mugwort crude protein and amino nitrogen contents markedly increased with fermentation. Thrombolytic activity determined from the size of the clear zone on a fibrin plate was higher for the Artemisiae asiaticae Nakai, especially in the fermented sample. Antioxidative activity according to DPPH(1,1-diphenyl-2-picrylhydrazyl) radical scavenging effects was higher for Artemisia capillaris Thumberg but no significant differences were found between the samples after fermentation. The body weights of hyperlipidemia-induced rats that were fed the mugworts for 4 weeks were lower than those of the control group. In all the mugwort-fed rats serum total cholesterol and LDL-cholesterol levels remarkably decreased. Furthermore the fermented mugworts were found to be more effective at decreasing triglyceride (TG) levels. It is also noteworthy that the highest HDL-cholesterol levels were observed in the rats treated with the fermented Artemisiae asiaticae Nakai. And fatty liver weights were higher in the rats fed Artemisia capillaris Thumberg. In conclusion the feeding of fermented Artemisiae asiaticae Nakai was effective for increasing thrombolytic activity and HDL-cholesterol levels as well as reducing TG levels in rats.

  • Rats that are fed a fructose-rich diet develop hypertension, insulin resistance, and hypertriglyceridemia. To elucidate whether altered expression levels of endothelin-1 and nitric oxide synthase are related to the development of insulin-resistant hypertension, we examined the present study. Male Sprague-Dawley rats were fed a fructose-rich diet for 5 weeks. Systolic blood pressure significantly increased in fructose-fed rats. While serum free fatty acid and plasma nitrite/nitrate levels did not significantly differ between the fructose-fed and control groups, plasma insulin and serum triglyceride concentrations significantly increased in the former. Endothelin-1 mRNA expression in the aorta increased in fructose-fed rats. Neither the protein expression of constitutive nitric oxide synthase nor that of inducible nitric oxide synthase were significantly affected by fructose feeding. However, nitrite/nitrate levels in the aorta were significantly increased. These results suggest that an increase in vascular endothelin-1 is an important contributing factor to the development of hypertension in fructose-fed rats. However, the vascular nitric oxide pathway may not be causally related to the development of fructose-induced hypertension.

  • Specific biomarkers to detect significant immunological or physiological responses would be extremely valuable on the development of feeding technique. Proteomics, the study of proteins within a cell or biological samples, may offer a novel approach to immunological or physiological monitoring of chicken responses to immune system. By studying the protein content of cells responding to a vaccine or growth factor, it may be possible to develop a metric for quantitating the magnitude of immunological or physiological responses. Proteomics could also provide a tool for obtaining valuable information regarding the underlying regulatory mechanisms and pathways in Korean Native Chicken by comparing with subspecies of KNC and other species, like Cornish and White Leghorns.

  • The effects of addition of activated carbon to diet of broiler on productivity and meat quality of broilers were investigated. 48 broiler raised for six week. The addition level of activated carbon to each group was added 0, 0.6, 0.9 and 1.2%, respectively. During the experimental feeding period, weekly gain and feed intake of treatment fed diets contain 0.6 and 0.9 percent activated carbon were higher compared with those fed on control diet, though effects of diets containing graded levels of activated carbon on the feed efficiency were not found. When broilers were fed activated carbon on crude protein level of birds were higher compared with that of control diet. Also, crude fat of broilers fed diet containing activated carbon were shown to decrease compared with those fed of control diet(p<0.05). The pH from activated carbon diets was rather higher than that of control(p<0.05). The content of VBN and TBARS was not significantly different among all treatments. The heating loss has tend to decrease in activated carbon diet groups(p<0.05). The WHC tend to be increase in activated carbon diet groups(p<0.05). Blood cholesterol was no significantly different.

  • In this study, we investigated the effect of silkworm, and its by-products on exercise endurance, muscle mass, and fatigue recovery using ICR mice model. Powders of silkworm, pupae, dongchunghacho, and silk powder were suspended in water and feed to mice for 2 weeks. The forced swimming time was increased by 4.3, 4.1 and 2.8 seconds after silkworm, pupae, and dongchughacho administration compared to DW fed group. Increases in exercise ability were achieved by difference mechanism according to feeding materials. Pupae increased muscle mass by 129% compared with the control group which may effect on elongation of swimming time. Dongchunghacho improved the plasma concentrations of fatigue markers such as creatinine, blood urea nitrogen (BUN), and D-lactate. Silkworm administration showed dual effect, the muscle mass induction (114% vs. control) and anti-fatigue (plasma creatinine, BUN, and D-lactate were 63, 75, and 78% vs. con) effect which contributed most elongated swimming time. In conclusion, silkworm and its by-products including pupae and dongchunghacho with the predominant protein and bioactive components improved muscle mass and showed anti-fatigue effect which could promote exercise performance ability.
