  • An experiment was conducted to evaluate the effects of low concentrations of organic and inorganic dietary trace minerals on broiler performance and trace mineral digestibility along the small intestine of 35-day-old broiler chickens reared under floor-pen conditions. Eight hundred male, day-old Cobb broiler chickens were randomly allocated to 4 dietary treatments (25 birds per pen with 8 replicates per treatment). Broilers fed diets supplemented with 4, 20, 40 and 30 mg/kg, respectively, of Cu, Fe, Mn and Zn from organic chelates and inorganic salts achieved the same body weight gain as those supplemented at the NRC levels (8 mg Cu, 40 mg Fe, 60 mg Mn and 40 mg Zn/kg, respectively) from inorganic salts. However, birds fed a control diet without any supplementation at dietary levels of 7.4-8.8, 60.1-69.2, 14.6-15.4 and 19.1-20.6 mg/kg of Cu, Fe, Mn and Zn, respectively, had decreased feed intake and growth rate. There was no significant difference in the digestibility of Cu in all regions of the small intestine. Throughout the small intestine the apparent absorption of Mn from both organic and inorganic sources was small, whereas the digestibility of Zn seemed to be more complex, exhibiting differences in the apparent absorption due to both mineral source and intestinal site. Therefore, the digestibility of organic Zn was improved (p<0.01) in the ileum compared to inorganic Zn. The digestibility of Zn in the duodenum was smaller (p<0.05) than that in the ileum.

  • In recent years, the consumption of livestock products were markedly decreased by awareness of world-widely occurred diseases including mad cow disease, Foot and mouth disease, Hog cholera, and Poultry Influenza virus. the consumers ara also wanting to have highly safe food such as organic animal products because of concerning about residual of antibiotics in animal products. However, disease control and impairment of productivity are the major problem in organic animal production. On these points of view, the present study was undertaken to investigate the effects of 1% or 2% of dietary probiotics fortified with various minerals on improvement of egg production and egg quality in old lay6r feeding low quality feed mainly composed of food waste, sesame meal, and rice bran. After 4 weeks of experimental feeding, the diameter of spreading of egg white was clearly decreased from 11.2cm of control eggs to 10.5m and 10.1m in 1% and 2% treatment group eggs, respectively. The color of egg yolk was 9.3 in control eggs but remarkably increased in treatment groups showing 10.1~10.2. Egg production was 75.8% in control layers but significantly increased to 79.8% of 1% treatment group and 82.9% of 2% treatment group layers. Egg weights (C : 66.3g, 1% : 73.2g, and 2% : 76.7g) and egg shell thickness (C : 0.33mm, 1% : 0.35mm and 2% : 0.36mm) were also increased by the addition of 1% or 2% of probiotics when compared to those of control group eggs. All together, it has been suggested that dietary addition of probiotics fortified with various minerals can improve the egg quality and egg production in layer's productivities by the recycling of organic waste resources such as food waste and agricultural by-products.

  • This study examined the effect of excess loading of calcium (Ca)and iron(Fe) on the bioavailability of minerals in both normal and Ca-and Fe-deficient rats. Three-week-old male rats were divided into four groups and fed experimental diets for six weeks, containing either normal (0.5%) or high(1.5%) Ca and normal (35ppm) or high (350ppm)Fe. Likewise, three-week-old male rats were first fed a Ca-and Fe-deficient diet for three weeks, and then fed one of four experimental diets for additional three weeks. In both normal and Ca-and Fe-deficient rats, ca contents of serum, liver, kidney and femur were not significantly affected by dietary Ca and Fe levels. Apparent Ca absorption(%) decreased in rats fed a high Ca diet regardless of dietary Fe levels. Magnesium(Mg) contents of serum, liver and femur significantly decreased in rats fed a high Ca diet. Fe contents of serum and liver significantly increased in rats fed a high-Fe diet, but decreased in rats fed a high Ca diet. Fe content of serum and liver significantly increased in rate fed a high-Fe diet, decreased in rats fed a high-Ca diet. Apparent Fe absorption increased in rats fed a high-Fe diet, and decreased in rats fed a high-Ca diet in Ca-and Fe-deficient rats, but dietary Ca did not seem to affect Fe absorption in normal rats. Phosphorus(P) contents of serum and femur were not significantly affected by dietary Ca and Fe levels in both normal and Ca-and Fe-deficient rats. Serum copper(Cu) decreased in rats fed a high-Fe diet, while serum zinc(Zn) decreased in rats fed a high-Ca diet in normal rats. Cu contents of liver, and Zn contents of serum and liver decreased in rats fed a high-Fe diet in Ca-and Fe-deficient rats. There results suggest that a dietary overload of Ca and Fe in both normal and Ca-and Fe-deficient rats may decrease mineral bioavailability leading to potential health problems.

  • Objective: A study was conducted to determine the chemical composition of banana meal and rice bran from Australia or South-East Asia and test the hypothesis that there are no differences in rice bran produced in different countries, but there are differences between full-fat and defatted rice bran. Methods: Two sources of banana meal and 22 sources of rice bran (full-fat or defatted) from Australia or South-East Asia were used. All samples were analyzed for dry matter, gross energy, nitrogen, amino acids (AA), acid hydrolyzed ether extract (AEE), ash, minerals, total starch, insoluble dietary fiber, and soluble dietary fiber. Banana meal was also analyzed for sugars including glucose, fructose, maltose, sucrose, stachyose, and raffinose. Results: Chemical analysis demonstrated that banana meal from the Philippines is primarily composed of starch. Full-fat rice bran from Australia had greater (p<0.05) concentrations of AEE, lysine, and glycine than samples from the Philippines and Vietnam. Full-fat rice bran from Australia and Thailand had greater (p<0.05) concentrations of gross energy and most AA than rice bran from Vietnam. Full-fat rice bran from Australia had greater (p<0.05) concentrations of tryptophan and manganese than all other sources, but full-fat rice bran from the Philippines contained less (p<0.05) zinc than all other sources of rice bran. Gross energy, AEE, and copper were greater (p<0.05) in full-fat rice bran compared with defatted rice bran, but defatted rice bran contained more (p<0.05) crude protein, ash, insoluble dietary fiber, total dietary fiber, AA, and some minerals than full-fat rice bran. Conclusion: Banana meal is a high-energy source that can be used as an alternative ingredient in livestock diets. Full-fat rice bran from Australia and Thailand contained more concentrations of AEE and AA than samples from the Philippines or Vietnam. Full-fat rice bran had more gross energy and AEE than defatted rice bran, whereas defatted rice bran contained more crude protein, ash, and total dietary fiber.

  • The purpose of the paper is to explore the current knowledge on the nutritional evaluation, cholesterol-lowering effect and antitumor activity of kimchi and its ingredients(Korean cabbage, garlic, red pepper powder, ginger and onion). Kimchi contains high contents of nutrients such as vitamins(ascorbic acid, $\beta$-carotene and vitamin B complex), minerals(calcium, potassium, iron and phosphorous), essential amino acids and dietary fiber. Kimch also contains high levels of lactic acid bacteria, allicin, capsaicin, organic acid, phenol compounds, flavonoid and sulfur compounds. The dietary fiber and lactic acid bacteria isolated from kimchi are effective in improving intestinal microflora of human. Isoluble dietary fiber shows anticancer activity, but soluble dietary fiber shows hypocholesterolemic effect. Lactic acid bacteria isolated from kimchi acts as a hypocholesterolemic or anticancer agent. A major ingredient of kimchi is mainly cruciferous and allium family vegetables, which were also reported to prevent cancer and atherosclerosis. It is suggested that kimchi is important not only as one of the traditional fermented Korean food but also as therapeutic agent for carcinogenesis and hypercholesterolemic state.

  • To confirm basic nutrient contents of Korean honey as a food material, we assessed New Zealand Manuka honey by measuring proximate components, vitamin C and minerals of 16 kinds of honey harvested in South Korea. The proximate composition of each honey sample was as follows: moisture content 18.45~29.84%, crude protein 0.10~0.95% (vs Manuka honey 0.23%), crude fat 0.02~0.60% (vs Manuka honey 0.34%), crude ash 0.01~.52% (vs Manuka honey 0.24%) and carbohydrate 67.90~80.94% (vs Manuka honey 79.39%), respectively. In the case of free sugars analyze by HPLC, fructose showed a content of 26.12~49.84% which was highest in acacia honey and lowest in sorbus honey. Content of glucose was 19.38~36.12% and lowest in chestnut honey, whereas sucrose, lactose, maltose were absent. Total sugar contents were 64.16% which was less than Manuka honey (70.23%) and vitamin C was not detected in all samples. Minerals were detected 15~25 kinds, including K, Ca, Mg, Zn, Fe, Cu, Mo and so on. Ca was high in order of linden > canola > codonopsis > hedysarum honey, and K was higher than in Manuka honey in order of chestnut > hedysarum > codonopsis > jujube honey. Especially, these results suggest that Korean honey have a better nutrient content profile than Manuka honey.

  • The present study was carried out to investigate the serum minerals profile in buffaloes (Bubalus bubalis) suffering from parturient haemoglobinuria (PHU) along with minerals profile of soils and fodders from the disease prone areas and their interrelationships. Serum samples were collected from 60 each of healthy and PHU affected buffaloes randomly selected from field cases. Serum samples were collected from each animal. Fifty composite soil samples were collected where PHU was prevalent. Fifty samples of fodders including leaves and stems being fed to the diseased buffaloes were collected. The difference in the levels of calcium and potassium between upper and lower soil surface of disease prone areas under study were statistically non-significant. The mean values of phosphorous, copper, iron, selenium and molybdenum in upper soil surface were significantly (p<0.05) higher than in lower soil surface. None of the fodders offered to the diseased animals met the dietary requirements of phosphorus and copper whereas none of the fodders was deficient in potassium, iron and selenium rather were having excess of potassium, iron and selenium. The concentration of calcium was adequate in lucerne, berseem, sarson and sorghum, while maize, sugarcane and wheat straw did not meet the required levels for dairy animals. Molybdenum contents in all fodders were adequate to meet the dietary requirements of the dairy buffaloes. Serum phosphorus, copper and selenium were significantly (p<0.001) lower whereas potassium, iron and molybdenum in buffaloes suffering from PHU were significantly (p<0.001) higher than in healthy buffaloes. It was concluded that phosphorous deficient soils play a major role by transferring this deficiency to plants and ultimately reaching to animals where hypophosphataemia is a consistent finding.
