  • Sixteen Harnai males were used to evaluate the influence of varying levels of fourwing saltbush hay on feed and water intakes as well as the blood serum mineral status in a completely randomized design. The animals were grouped randomly into four, with four animals in each. The four groups were randomly allotted low, medium, high and very high levels of saltbush hay supplementation in addition to wheat straw. The animals were given fresh water at free of choice. Weekly body weight was recorded for each individual animal. Blood serum was collected for mineral contents. The experiment lasted for eight weeks. The inclusion of saltbush leaves in the diet showed a non-significant effect on the total dry matter intake. There has been a significant increase in the water intake when very high levels of saltbush were included in the ration. Lower levels showed no effect on the water intake. The animals maintained their body weight from week 1 to week 8. No treatment by weeks interactions on the potassium and sodium levels were detected. However higher levels of saltbush increased significantly the potassium and sodium contents in the serum. Calcium contents were significantly(p<0.01) lowered with the inclusion of saltbush leaves in the diet. Whereas Phosphorous contents showed an increasing(p<0.05) trend with the higher levels of saltbush. No clinical or sub-clinical toxicological symptoms were observed in the sheep with the higher mineral contents.

  • This study was carried out to investigate the effects of addition of milk minerals (2%) and α-tocopherol (0.03%) on lipid oxidation and minerals content of emulsion-type sausages. The pH values of sausage containing milk mineral alone and combined with milk mineral and α-tocopherol were significantly (P<0.05) higher than those for control and α-tocopherol. The POV values of sausage containing combined with milk mineral and α-tocopherol were significantly (P<0.05) lower than those of control and α-tocopherol during storage. The TBARS values of sausage containing milk mineral alone and combined with milk mineral and α-tocopherol were significantly (P<0.05) lower then those for control and α-tocopherol. The Mg, Ca and P content of sausage containing combined with milk mineral and α-tocopherol were significantly (P<0.05) higher than those of control and the other. The K content of sausage containing α-tocopherol were significantly (P<0.05) higher than those of control and the other. Milk mineral, when used with α-tocopherol, provided no additional effect on lipid oxidation, but mineral contents were higher than those of control.

  • The purpose of present study was to analyze mineral contents in various tissues and investigate theirs relation with bone mineral density (BMD) in rats. Fifteen Sprague-Dawley rats were fed standard diet for 4 weeks. Body weight gain, feed intake, and feed efficiency ratio were 41.00 g/week, 171.15 g/week, and 0.24 respectively. Among 12 minerals in serum, Ca is the highest with 6.86 mg/dl. Serum Mg, Se, and Cu were 2.52 mg/dl, 0.23 mg/dl and 0.22 mg/dl respectively. Mg contents in liver, spleen, and kidney were $246.36\;{\mu}/g$, $105.01\;{\mu}/g$, and $273.38\;{\mu}/g$ respectively. Tibia contents of Ca, Mg, Zn, Fe and V were 194.91 mg/g, 23.10 mg/g, 0.60 mg/g, 0.35 mg/g and 0.14 mg/g respectively. BMDs of right tibia and spine were 122.04 mg/cm and $153.61\;mg/cm^2$. There were significantly positive correlations between tibia BMD and Se (p<0.05), tibia BMD and V (p<0.01), spinal BMD and V(p<0.05), respectively. It's expected that these results are used as a reference data in following study to elucidate physiological function of minerals.

  • A lot of landslides were occurred in Gangnung, Macheon and Geochang areas by Typhoons such as RUSA(2002) and MEAMI(2003). Soil properties of these areas are investigated regarding geological conditions in this study. The shallow plane failure were occurred in Gangnung and Geochang areas, whereas the deep circle failure were occurred in Macheon area. The matrix in Gangnung and Geochang areas was composed of Granite, and the matrix in Macheon area was composed of Gabbro. The disturbed and undisturbed soils were sampled in these areas. As the results of laboratory tests using sampled soils, the coefficient of permeability in Granite region is lower than that in Gabbro region. In the cases that the silt and clay contents are included less than 4% for the soils of Granite region and less than 7% for the soils of Gabbro region, the coefficients of permeability are rapidly increased for both soils. In addition, the simple equations for predicting the coefficients of permeability are proposed using the effective particle size and the silt and clay contents according to geological condition.

  • This study was conducted to investigate the effect of dietary zinc on macro mineral contents of high fat diet-induced obese rats. The obese group was divided into three groups by zinc levels of diet, such as low (50% requirement), adequate (100%) and high (200%) levels of dietary zinc. The calcium, magnesium, sodium and potassium contents in serum and organs were measured by ICP. There were no significant differences in the food intake, weight gain and feed efficiency ratio among the different dietary zinc levels. Also, the liver, kidney and spleen weight did not show the significant differences among each level of dietary zinc. However, serum sodium and potassium concentrations in the low zinc diet group were significantly higher than in the other diet groups. In high zinc diet group, the calcium contents of liver was significantly higher than in the other diet groups, magnesium and potassium contents of liver were higher than in the low zinc diet group. The sodium contents of liver and magnesium and potassium contents of spleen were significantly lower in the low zinc diet group than in the other diet groups. In conclusion, the macro mineral contents of serum, liver and spleen in obese rats were changed by dietary zinc levels. Especially, the low zinc diet group considerably changed of macro mineral contents in organs. Therefore, it may be suggested that adequate level of dietary zinc in obese individuals should be required.

  • Experiments were conducted on established grassland sward at Gongiam, Kwangju, and Kyung-gi in Korea from 1995 to 1997. The influence of mineral-N fertilizer or animal manure(AW) on herbage dry matter(DM) yield, N yield, the recovery of AM-N, and soil N and organic matter(0M) content in the mixed sward('potomac' orchardgrass, 'fawn' tall fescue, and 'kenblue' Kentuky bluegrass) was investigated. The treatments were replicated three times in a split plot block design. AM(the main plots) was applied at 200kg N ha ' year ' on each plot. The types of AM were cattle feedlot manure(CFM), pig manure fermented with sawdust(PMFS) and Korea native cattle slurry(KNCS). Three levels of mineral-N fertilizer, as urea, ranging from 0 to 200kg N $ha^{-1}\;year^{-1}$ in 100kg increments, were superimposed on each plot. The fertilizers and AM were applied in two equal dressings(the end of March and middle of November). AM and mineral fertilizer had significant effects(p<0.05) on herbage DM and N yields. Herbage yields in KNCS were higher than those in CFM and PMFS(p
