Objectives: Two historical evidence supported the concept of Gamrosu. The first one was Jeho-tang, a selected thirst quencher in Chosun Dynasty and the second one was Saeng-Maek-san, Dongeuibogam's recommendation as one of the qi-vigorating summer beverages. Gamrosu is a modified fasting therapy beverage which is manufactured from those two prescriptions and the carbohydrates (420.6 kcal/d). A retrospective observational study was conducted to evaluate the clinical outcomes. Methods: Thirty-three cases were reviewed at three local Korean Medical clinics that each site's participant has finished the modified fasting for 10 consecutive days. Clinical outcomes were reviewed at pre- and post-fasting sessions by retrieving the changes of body composition, blood pressure, blood chemistries & urine tests, and subjective symptoms & fatigue scores. Results: Demographics of the observed participants were 17 of male and 16 of female. Post-Gamrosu session, -6.89% of body weight, -8.97% of body fat mass were reduced with the nutrition indices being improved (P<0.001). -8.72% of systolic blood pressure, -39.86% of serum triglyceride, -6.75% of fast blood sugar and -8.12% of waist circumference were improved (P<0.05). The levels of high sensitivity C-reactive protein (-58.34%), CRP (-43.55%) and eosinophil (-21.30%) showed the significant diminished profiles (P<0.05). Liver/kidney functions and the standard of electrolytes were maintained within normal range in stable manners. The fatigue scale scores indicated significant lower scores. Conclusions: Taken together, obesity-related clinical outcomes after a modified fasting therapy with Gamrosu were sufficiently feasible and the observed findings should be considered for further prospective clinical studies.

This study investigated the effects of the dietary supplementation with gaeddongssuk (Artemisia annua L.) powder on blood biochemical compositions, meat lipids and fatty acid profiles of the broiler chicks. One hundred male broiler chicks were divided randomly into five groups: group fed with basal diet (Control); group supplemented with 2.5% antibiotics in the drink water (Antibiotics), and groups supplemented gaeddongssuk powder with 5% (BG-I), 6% (BG-II), and 7% (BG-III) in the basal diets. Levels of total lipid and LDL-C in serum of broiler chicks were significantly lower in the groups supplemented with gaeddongssuk compared to the Antibiotics group. Contents of triglyceride and total cholesterol were significantly lower in the BG-III. HDL-C level was significantly higher in BG-I and BG-II compared to the Antibiotics group. Antioxidant activity of serum in the BG-II was significantly higher than Control and Antibiotics groups. Lipid peroxide contents in the BG-I and BG-II were significantly lower than to the Antibiotics group. Total lipids level of breast and legs meat was significantly lower in the groups supplemented gaeddongssuk compared to the Antibiotics group. Total cholesterol level of breast meat was significantly lower in the groups supplemented with gaeddongssuk compared to the Antibiotics group. UFA/SFA ratio of breast and legs meat from the BG-II was tend to higher compared to Control and Antibiotics groups. Taken together, these results suggest that dietary supplementation of gaeddongssuk with 6% could be applicable as the possibility to improve blood biochemical compositions and meat lipids properties in broiler chicks.

The present study was undertaken to clarify the changes in blood chemical values of indigenous Korean striped calves according to age. Blood samples were collected from 15 calves (8 females and 7 males) reared at the Gyeongsangbukdo Livestock Research Institute and the levels of various chemicals in serum were analyzed. The mean total protein, albumin and globulin concentration in calves increased from 2 weeks after birth, and the levels in females were higher than those in males at 8 weeks after birth. The mean glucose concentration increased significantly at 2 weeks after birth. The mean blood urea nitrogen concentration increased from 2 weeks after birth, whereas the mean creatinine concentration decreased significantly from 2 weeks after birth. The mean uric acid concentration increased gradually from 2 weeks after birth. The mean glutamic oxaloacetic transaminase and glutamic pyruvic transaminase concentration increased significantly from 2 weeks after birth. The mean total bilirubin concentration tended to decrease from 2 weeks after birth. The mean triglyceride, total cholesterol and high density lipoprotein cholesterol concentration increased significantly from 2 weeks after birth. In conclusion, the data obtained from this study may be valuable as a standard for interpreting results of biochemical analyses in indigenous Korean striped calves.

This study was conducted to investigate the antibiotic effects of bee venom (Apis mellifera) on the growth performance and blood characteristics in broiler chicken. 1-day-old broiler chicks were randomly divided into 3 groups with 3 replicates of 5,000 birds each. The treatments were control without antibiotic and bee venom, 0.5ppm or 1ppm bee venom. The final body weight and body weight gain were significantly higher in bee venom than control (P<0.05). The feed conversion ratio in all treated groups were significantly improved as compared to that of control (P<0.05). No significant differences among the groups were observed in the contents of total cholesterol, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total protein, albumin and globulin in blood serum. The white blood cell, red blood cell, heterophil, lymphocyte, and stress indicator (heterophil:lymphocyte rate) were not significantly different among the groups. The superoxide dismutase-like activities in the groups that were water containing bee venom were significantly increased compared to those in the control group (P<0.05). It has been suggested that bee venom promotes the growth of broilers without any negative effect when added in broiler water.

Objective: Sixty Pengbo semi-wool sheep ewes (approximately 1.5-years-old; $31.33{\pm}0.43kg$) were randomly assigned to two groups, either grazing (G) or dry lot feeding (D), to examine the effects of traditional daily grazing and dry lot feeding on performance and blood metabolites during the cold season in Tibetan Plateau. Methods: The ewes in the G group were grazed continuously each day and housed in one shed each evening, while the ewes in the D group were housed in another shed all day. All animals were fed 400 g/d of commercial concentrate, and grass hay was available freely throughout the experimental period. Results: Compared with the G group, the ewes in the D group had higher (p<0.05) live weight and weight gain. The D group ewes had greater (p<0.05) numbers of white blood cells and platelets, while they had lower (p<0.05) platelet-large cell ratios, cholesterol, high-density lipoprotein cholesterol and glutathione peroxidase, as compared with the G group ewes. Additionally, three serum metabolites, abscisic acid, xanthoxin and 3,4-dihydroxy-5-polypren, were upregulated (p<0.05) in the G group in comparison with the D group. Conclusion: In conclusion, a dry lot feeding regime during the winter and spring period will increase the productivity of sheep and improve blood physiological and biochemical profiles.

Objective: A feeding trial was carried out to determine the effect of dietary inclusion of silymarin seed extract on growth performance, nutrient digestibility, excreta microbiota, excreta gas emission, blood profiles, and meat quality in broilers. Methods: A total of 1,088 one-day-old Ross 308 broiler chicks (mixed-sex) with an initial body weight of 42.34±0.82 g, were randomly allocated into 1 of 4 dietary treatments with 17 replicates of 16 chicks per cage and fed a basal diet supplemented with 0%, 0.02%, 0.04%, and 0.06% of silymarin. Results: The inclusion of silymarin supplementation linearly increased the body weight of broilers during days 7 to 21 and 1 to 35 days. On day 35, broilers fed a diet containing graded levels of silymarin supplementation linearly increased the nutrient digestibility of dry matter, gross energy, and nitrogen and cecal Lactobacillus counts (p = 0.038). While silymarin supplement linearly reduced the methyl mercaptans (p = 0.039) and acetic acid (p = 0.007) emission in broilers. No significant effects were observed on the blood profile. Relative weights of organs such as breast muscle, bursa of fabricius were increased (linear effect, p<0.05), water holding capacity was enhanced by increasing the silymarin level from 0% to 0.06%. A linear reduction (p>0.05) in drip loss from meat samples during days 1, 3, 5, and 7 by the addition of graded level of silymarin to the diet. Conclusion: An increasing level of silymarin supplementation to the diet of broiler would be beneficial to enhance growth performance, nutrient digestibility, excreta microflora, blood profile, and meat quality traits.

This study was carried out to compared the characteristics of the underweight university students with those of overweight university students. The surey was carried out by self-questionnaires with 97 underweight and 156 overweight university students. The results are summarized as fellows. Breakfast was skipped in 37.1% of underweight and 46.2% of overweight students and it appeared overweight students eat faster than underweight students. The 16.5% of underweight and 75.0% of overweight students have correct perception about their body image. The percentage of weight control experience were 25.8and 55.8 in the underweight and overweight students, respectively. Blood levels of lipid profiles(triglyceride, LDL cholesterol, and HDL cholesterol), hemoglobin, AST and ALT were anaylzed. Plasma levels of triglyceride, total cholesterol, LDL cholesterol, and HDL cholesterol of underweight students were 96.41, 143.75, 97.53 and 56.27 mg/dl, and those of overweight students were 107.99, 164.31, 100.08 and 53.64 mg/dl, respectively. Blood parameters were in normal range in both group. Plasma triglyceride, total cholesterol and LDL cholesterol levels o( overweight students were higher than those of underweight students. On the other hand, plasma HDL cholesterol levels of overweight students were lower than those of underweight students. Plasma levels of AST and ALT were in normal range in both group. However, AST and ALT levels of overweight students were higher than that of underweight students. Therefore they should have a nutritional education program to improve their dietary and living habits for overweight students' health. And nutritional education program should be organized practically and systematically

Objective: The experiments were carried out to measure the effect of multivitamin, acidifier and Azolla on growth performance, profitability and lipid profiles of blood of broiler chickens to produce safe and cost effective broilers. Methods: In experiment 1, 240 day-old Cobb-500 broiler chicks were fed diets; $D_1$ (control), $D_2$ ($D_1$ with 1 mL multivitamin/liter water), $D_3$ ($D_1$ with 1 mL acidifier/liter water), $D_4$ ($D_1$ with 1 mL multivitamin and 2 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication. In experiment 2, 150 day-old Cobb-500 broiler chicks were fed diets; $T_1$ (control), $T_2$ (5% Azolla in the diet), $T_3$ (7% Azolla in the diet) and $T_4$ ($T_1$ with 1 mL multivitamin and 1 mL acidifier/liter water) having 3 replications in each, and 20 chicks/replication in control, and 10 chicks/replication in the remaining dietary treatment groups for 35 days. Results: In experiment 1, the highest live weight was observed in $D_4$ (p<0.05), however, feed intake was statistically similar between diets (p>0.05). The lowest feed conversion ratio (FCR) (p<0.001) and mortality (p<0.05) were observed in $D_2$ followed by $D_4$, $D_1$, and $D_3$, respectively. There were no significant differences between diets for feed cost and net profit (p>0.05). However, evidently but not significantly, the highest net profit was obtained in $D_2$ followed by $D_4$, $D_1$, and $D_3$, respectively. In experiment 2, the highest live weight (p<0.05) and feed intake (p<0.001) were observed in $T_4$. Mortality (p<0.01), FCR (p<0.01), feed cost (p<0.05) and net profit (p<0.05) were significantly different among diets. Considering net profit, $T_2$ was the best performing dietary group followed by $T_3$, $T_1$, and $T_4$, respectively. The lowest lipid profiles were observed in $D_3$ followed by $D_1$, $D_4$, and $D_2$, respectively (p<0.05). In experiment 2, the lowest total cholesterol, TG, and the highest amount of high density lipoprotein were observed in $T_2$, followed by $T_3$, $T_1$, and $T_4$, respectively (p<0.05). Evidently but not significantly, low density lipoprotein was the highest in $T_2$ followed by $T_3$, $T_4$, and $T_1$, respectively (p>0.05). Conclusion: In conclusion, Azolla and acidifier reduced lipid profiles of broiler chickens. Considering net profit and lipid profiles, 5% Azolla may be the suitable dietary group for producing safe and profitable broilers. However, more studies are needed to confirm this study prior to suggesting using Azolla in the poultry industry.
