  • This experiment was conducted to evaluate the effects of increasing concentrations of crude glycerin (CGLY) in diets on nutrient utilization, ruminal fermentation characteristics, and nitrogen utilization of goats. Four male crossbred (Thai Native${\times}$Anglo Nubian) goats, with an average initial weight of $26{\pm}3.0$ kg, were randomly assigned according to a $4{\times}4$ Latin square design with four 21 days consecutive periods. Treatments diets contained 0%, 5%, 10%, and 20% of dietary DM of CGLY. Based on this experiment, there were no significant differences (p>0.05) among treatment groups regarding DM intake and digestion coefficients of nutrients (DM, OM, CP, EE, NDF, and ADF). Likewise, mean serum glucose, BHBA, and PCV concentrations were not affected (p>0.05) by dietary treatments, whereas serum insulin concentration linearly increased (L, p = 0.002) with increasing the amount of CGLY supplementation. Ruminal pH, $NH_3$-N, and BUN concentration were unchanged by dietary treatments, except for 20% of CGLY, $NH_3$-N, and BUN were lower (p<0.05) than for the diets 10% of CGLY, while the difference between the diets 0%, 5%, and 20% of CGLY were not significant. The amount of N absorption and retention were similar among treatments. Based on this study, CGLY levels up to 20% in total mixed ration could be efficiently utilized for goats and this study elucidates a good approach to exploiting the use of biodiesel production for goat production.

  • To investigate the anti-complementary and cytotoxic effects of oriental prescription, Kuseonwangdogo, on the proliferation of preadipocyte 3T3- L1 cells, we examined biological effects of Kuseonwangdogo. The results obtained were as follows. 1. After 14 days, the body weight of rats treated with Kuseonwangdogo decreased more than that in the control group (p<0.05). However, the weights of liver, spleen and kidney were unchanged. In serum biochemical test, we examined the level of glucose (GLU) and glutamic pyruvic transaminase (GPT). The levels of GOT and CHOL in serum were decreased remarkably by the administration of Kuseonwangdogo (p<0.05). The haematological examination of the tested group showed significant increment of white blood cells (WBC), hemoglobin concentration (HGB), mean corpuscular hemoglobin (MCH) and monocyte (MO). 2. The effect of Kuseonwangdogo on the proliferation of 3T3-L1 cells was tested by the sulforhodamin B(SRB) assay. The high concentration ($100{\mu}l\;and\;200{\mu}l$) of extracts inhibited the proliferation of 3T3- L1 cells. The p-value was <0.01, respectively. 3. The extract of Kuseonwangdogo showed a potent anti -complementary activity. It was suggested that the active principle may be a kind of polysaccharide molecule. 4. The cytotoxic effects of Kuseonwang dogo and its composing herbs in human liver cells (WRL68) and monkey kidney cells (Vero) were examined by the SRB and 3- (4,5- Dimethylthiazol-2-yl) -2,5 diphenyl-2H- tetrazolium bromide (MTT) assay. Cytotoxic effects were not observed.

  • This study investigated the effects of ozone-produced oxidants (OPO) on the growth, hematology, and histology of olive flounder Paralichthys olivaceus (average weight 500 g), raised in an ozonated semi-recirculating aquaculture system. The system was ozonated to maintained OPO concentrations of 0.004 (Control), 0.014 (OPO15), and 0.025 (OPO25) mg $Cl_2/L$ in culture tanksfor 26 days. The specific growth rate, feed conversion ratio, and survival rate did not significantly differ among the groups (P>0.05), while the daily feeding rate decreased OPO-dose-dependently (P<0.05). OPO appeared to affect the gill, hepatopancreas, and kidney tissues of fish from ozonated tanks. Hematologically, OPO affected some blood indices. The levels of chloride, glucose, glutamic oxaloacetic transaminase, and glutamic pyruvic transaminase were significantly increased in the ozonated groups, while the total cholesterol and cortisol decreased dose-dependently. These results imply that long-term exposure of olive flounder to an OPO concentration ${\geq}0.014mg\;Cl_2/L$ might result in damage to the gill, hepatopancreas, and kidney tissues and cause physiological stress, albeit with no apparent short-term effects on growth or survival.

  • Purpose: Vitamin D deficiency is a condition widespread throughout the world. Recent studies have suggested that vitamin D deficiency was associated with obesity and metabolic syndrome. The purpose of the study was to examine the relationship between vitamin D deficiency and nonalcoholic fatty liver disease (NAFLD) in adolescents. Methods: The data were obtained from the Korean National Health and Nutrition Examination Survey from 2008-2014. A total of 3,878 adolescents were included in the study. Vitamin D deficiency was defined as a 25-hydroxyvitamin D concentration <20 ng/mL and suspected NAFLD was defined as an alanine transaminase concentration >30 U/L. Results: Vitamin D deficiency was noted in 78.9% of the studied population. Age, body mass index, waist circumference, and blood pressure, glucose, cholesterol, and triglyceride levels were significantly higher in adolescents with suspected NAFLD than in adolescents without suspected NAFLD, while the mean vitamin D level was significantly lower in adolescents with suspected NAFLD. The multivariate-adjusted odds of suspected NAFLD were higher with increased age, male gender, obesity, and metabolic syndrome. Individuals with vitamin D deficiency were at higher risk of suspected NAFLD (odds ratio, 1.77; 95% confidence interval, 1.07-2.95) after adjusting for age, gender, obesity, and metabolic syndrome. Conclusion: Vitamin D deficiency was associated with suspected NAFLD, independent of obesity and metabolic syndrome, in adolescents.

  • Mirror carp Cyprinus carpio nudus (weight 42.0±3.8 g, length 14.3±0.4 cm) were exposed to different concentrations of waterborne copper (0, 100, 200, 400, 800, and 1,600 ㎍ Cu2+·L-1) at 20.3℃ for 96 h. The lethal concentration 50 of waterborne copper was 1,176.45 ㎍ Cu2+·L-1. Among hematological parameters, red blood cell count was significantly decreased, whereas there were no significant changes in the hemoglobin concentration and hematocrit value. Among the inorganic plasma components, calcium was significantly decreased following copper exposure. Conversely, organic plasma components such as glucose and total protein were significantly increased. Similarly, enzymatic components, such as aspartate transaminase, alanine transaminase, and alkaline phosphatase, were also significantly increased. These findings suggest that the copper exposure is detrimental to the survival rates and physiology of C. carpio nudus.

  • This study aimed to evaluate the effects of polyethylene microplastic (PE-MPs) via measuring the growth performance, hematological parameters, and antioxidant responses in Korean rockfish Sebastes schlegelii exposed to waterborne polyethylene microplastic with dimensions of 22-71 ㎛. S. schlegelii (mean weight, 34.55±5.82 g; mean length, 12.59±0.79 cm) were exposed to PE-MPs at concentrations of 0, 400, 800, 1,600 and 3,200 ㎍/L for 10 and 20 days. PE-MPs significantly affected growth performance, hematological parameters, plasma components, and antioxidant responses in a concentration-dependent manner. At a concentration ≥1,600 ㎍/L, PE-MPs significantly decreased body weight gain and specific growth rate, and significantly increased the hepatosomatic index. Hematological parameters showed a significant decrease in total red blood cell count and hemoglobin levels. Plasma components showed a significant increase in glucose, aspartate aminotransferase, and alanine transaminase levels, whereas total protein, calcium, and magnesium levels significantly decreased. Exposure to ≥1,600 ㎍/L PE-MPs also induced reactive oxygen species generation in the gill and liver, significantly increasing superoxide dismutase and catalase activity. These findings suggest that exposure to ≥1,600 ㎍/L PE-MPs could significantly change growth performance, hematological parameters, plasma components, and antioxidant responses, resulting in physiological toxicity.

  • A feeding trial was carried out to determine the effects of chromium methionine (Cr-Met) chelate and forage level over two years, $1^{st}$ fattening and $2^{nd}$ fattening period on growth parameters, carcass characteristics and blood metabolites of 46 Korean native (Hanwoo, Bos Taurus, $BW=183{\pm}44kg$) steers. Treatments were: 1) Steers in the low forage (LF) group were fed diets that consisted of 60% concentrate and 40% forage; 2) Steers in the high forage (HF) group were fed diets that consisted of 40% concentrate and 60% forage. Following the $1^{st}$ fattening period, steers ($BW=480{\pm}37.6kg$) were randomly assigned to four treatment groups: LF (40 F plus no Cr-Met supplementation in the $2^{nd}$ fattening period), LFCM (40LF plus added 400 ppb of Cr-Met during the $2^{nd}$ fattening period), HF (60 F plus no added Cr-Met during the $2^{nd}$ fattening period) and HFCM (60 F plus added 400 ppb of Cr-Met in the $2^{nd}$ fattening period). Dry matter intake of the treatment diets did not differ during the raising and $1^{th}$ fattening period (P > 0.05). The ADG in the raising period showed no difference between the 40 F and 60 F groups (P > 0.05). Carcass characteristics including rib-eye area and meat yield index were higher in HF than the other treatment groups (P < 0.05). The HF group tended to show a higher (P = 0.08) marbling score than the LF group whereas the HFCM group showed a higher marbling score than the LFCM group (P < 0.05). HDL was higher and LDL lower in groups fed with Cr-Met than in other groups whereas glucose showed the lowest value in HF group (P < 0.05). Triglyceride (TG), Cholesterol, PUN and total protein (TP) were the same among all treatment groups (P > 0.05). The Insulin concentration in the blood was significantly higher for the HFCM group than for the LF, LFCM and HF groups (P < 0.05). It is concluded that supplementation of chromium-methionine chelate could improve meat quality in beef steers.

  • Objectives : This study was undertaken to verify the effect of Gangjihwan(Di-fatty, DF) composed with Pakistani Ephedra Herba on nonalcoholic fatty liver disease(NAFLD) using high fat diet-fed male mice. Method : Eight-week old C57BL/6N mice were used for all experiments. Standard chow diet-fed mice were used as normal group and high fat diet-fed NAFLD mice were randomly divided into 5 groups: control, atorvastatin, DF(1), DF(2) and DF(3). After 8 weeks, mice were treated with water, atorvastatin(10mg/kg) and DF(40, 80, 160mg/kg) for 8 weeks. And we investigated body weight gain, plasma lipid and glucose metabolism, histological analysis for liver on the mice. Results : Compared with controls, DF-treated mice had very significantly lower body weight gain and lower visceral adipose tissue weight, the magnitudes of which were prominent in DF(3). Consistent with their effects on body weight gain, DF-treated mice had lower blood total cholesterol and triglyceride level compared with controls. Consistent with their effects on body weight gain and blood plasma lipid level, DF-treated mice had lower liver weight and hepatic lipid accumulation of DF-treated groups was significantly decreased than control group. Also Blood plasma AST, ALT and ${\gamma}$-GT concentration were not changed by DF, and these results may indicate DF do not show any toxic effects. Conclusions : These results suggest that DF effectively improves NAFLD. DF reduces liver weight and prevents lipid accumulation of hepatocyte by reducing body weight gain and modulating blood plasma lipid metabolism levels.

  • This study was designed to evaluate the effects of fructose(F) or sucrose(S) and guar gum intake on carbohydrate and lipid metabolism in 15-week-old male Goto-Kakizaki(GK) rats. Fifty rats were randomly assigned to 5 groups which were different in carbohydrate(25% of carbohydrate) and fiber(5% w/w) sources. The carbohydrate(CHO) sources of each group were comstarch(control group, 100% of CHO), fructose with cellulose(F), fructose with guar gum(FG), sucrose with cellulose(S), and sucrose with guar gum(SG). Each group was fed exterimental diet for 4 weeks. We measured food intake, body weight gain, adipose tissues weight and organs weight. We conducted oral glucose tolerance test(OGTT) and measured plasma insulin concentration to examine carbohydrate metabolism. To evaluate lipid metabolism, we measured the lipid profile of plasma, liver and feces. Food intake and weight gain of FG or SG groups tended to be less than those of F or S groups. Perirenal and epididymal fat pad weights of SG group were significantly lower than those of S group and those of FG group tended to be lower than those of F group. In OGTT, blood glucose values of F or S groups were significantly higher than those of C group, and FG or SG groups tended to be lower than those of F or S groups during the experimental time. The area under the curve(AUC) of C group was significantly highest among the groups, AUC and plasma insulin concentration of FG or SG groups tended to be lower than those of F or S groups. Plasma and hepatic triglyceride (TG) of FG and SG groups were significantly lower than those of F and S groups, plasma and hepatic total lipid(TL) and total cholesterol(TC) of FG and SG groups tended to be lower than those of F and S groups. Fecal TL, TG and TC of FG or SG groups tended to be higher than those of F and S groups. In conclusion, intake of guar gum should improve carbohydrate and lipid metabolism in partial substitution of fructose or sucrose for cornstarch in GK rats.

  • In this experiment, the effects of cage density (CD) and probiotic supplementation (PS) on laying performance, metabolic profile, and egg quality in peak-producing hens were evaluated. After blocking according to the cage location, Lohman layers (n = 180, 46 wks of age) were allocated randomly to two levels of CD (540 vs. 360 $cm^2$/hen) and three levels of PS (0, 0.15, and 0.30%). Probiotic contained Enterococcus faecium culture (10${\times}$10$^9$ cfu/g). Egg production (EP) and feed consumption (FC) were measured daily; egg weight (EW) was measured bi-weekly; BW was measured before and after the experiment; and blood samples were obtained at the end of the experiment. The data were analyzed using two-way ANOVA. Increasing CD decreased FC (125.0 vs. 120.8 g/d, p<0.0001) and FCR (1.93 vs. 1.87, p<0.0001) and did not alter EP, EW, and BW. Increasing level of PS linearly decreased FC (p<0.02) and FCR (p<0.006). Averages were 123.9, 123.2, and 121.6 g/d for FC and 1.91, 1.92, and 1.86 for FCR in hens supplemented with 0, 0.15, and 0.30% probiotic, respectively. Hens placed in high-density cages had greater serum corticosterone concentration than hens placed in normal-density cages (12.8 vs. 11.3 $\mu$g/dL, p<0.04); CD did not affect concentrations of other metabolites. Increasing level of PS linearly increased serum glucose, albumin, and creatine concentrations and quadratically increased total protein, globulin, Ca, and P concentrations. Average concentrations (mg/dL) were 260, 297, and 305 for glucose; 6.28, 8.09, and 7.58 for total protein; 1.98, 2.48, and 2.38 for albumin; 4.30, 5.62, and 5.19 for globulin; 0.40, 0.52, and 0.54 for creatine; 16.0, 16.5, and 16.3 for Ca; and 6.27, 8.14, and 7.17 for P in hens supplemented with 0, 0.15, and 0.30% probiotic, respectively. There was no effect of CD on egg quality. Increasing level of PS linearly improved yolk color (YC) and quadratically increased albumen index (AI) and Haugh unit (HU). The mean values were 9.67, 9.75, and 10.58 for YC; 8.94, 6.93, and 8.72% for AI; and 85.6, 74.9, and 82.9 for HU for hens supplemented with 0, 0.15, and 0.30% probiotic, respectively. There was also CD by PS effect on FC, EP, and serum glucose, total protein, albumin, globulin, creatine, Ca and P concentrations. In conclusion, increased CD partially depressed laying performance and caused stress. Probiotic supplementation improved laying performance and metabolic profile. It also partially alleviated the adverse effects of stress resulting from increased caging density.
