  • The effect of fat supplementation of high calcium (Ca) diets on the performance, intestinal pH, body composition and size and weight of organs in growing chickens were investigated in two experiments. Growing chickens tolerated a high dietary level of Ca (22.5 vs 12.1 g/kg) in the presence of 6.3 g/kg of available phosphorus without any significant effect on performance. Intestinal pH was significantly increased by the addition of excess Ca and fat which probably created the right pH for the formation of insoluble Ca soaps. Excess dietary Ca increased carcass linoleic acid concentration at the expense of palmitic and stearic acid contents, whilst the addition of sunflower oil (80 g/kg diet) to the diet increased carcass linoleic acid concentration at the expense of palmitic acid content of the carcass. Intestinal and visceral organ size and weight were not influenced by excess Ca or fat. However, there was a non significant increase in the intestinal dry weight per unit of length caused by excess dietary Ca. It was concluded that excess dietary Ca of 22.5 g/kg did not significantly influence the performance of meat chickens. However, excess Ca increased intestinal pH and altered carcass fatty acid composition. Fat supplementation did not alter intestinal pH with high Ca diets. Excess dietary fat altered carcass fatty acid composition and reduced protein content. Intestinal and visceral organ size and weights were not influenced by excess dietary levels of Ca of fat.

  • The effect of defatted and dehydrated beef muscle on the physical properties of thermoplastically extruded defatted soybean, cottonseed, peanut and sunflower seed flours were investigated. To minimize the adverse effect of meat fat and to increase the mixing efficiency of the meat with defatted oilseed flours at a given moisture level, beef muscle was extracted with chloroform-ethanol(2 : 1) at 2$0^{\circ}C$ and air dried. The variety of oilseed flours used had greater effects on color, expansion, bulk density, water absorption rate and textural strength of the extrudate than did the added level of defatted, dehydrated beef muscle (0 to 20% on a dry weight basis).

  • Opportunistic mycotic infection of mammary gland due to Candida tropicalis is described in a 7-year-old Holstein Friesian cow with a history of prologned use of antibiotics and corticosteroids. C. tropicalis was repeatedly isolated from the mastitic milk on simplified sunflower seed medium at 30$^{\circ}C$. The pathogen was directly detected in the infected milk by 'PHOL' technique. Microscopic examination of Gram stained smears of milk sediment revealed numerous yeast cells and hyphae morphologically consistent with Candida spp. In vitro drug sensitivity test indicated that C. tropicalis was sensitive to nystatin. Chemotherapy with intramammary infusion of nystatin was successful as evidenced by clinical and mycological observations. It emphasizes the growing significance of Candida spp. and other opportunistic fungal pathogens in Veterinary medicine.

  • The aim of this study was to isolate mesophilic chicken feather-degrading bacteria and to evaluate feather hydrolysate as alternative biofertilizer. Isolate RS7 was isolated from compost and identified as Bacillus pumilus according to API analysis and l6S rDNA sequencing analysis. Chicken feathers were completely degraded after 5 days of cultivation at $30^{\circ}C$. Feather hydrolysate treated by B. pumilius RS7 positively influenced Helianthus sannuus L. (sunflower) growth (e.g. growth rate, number and dry weight of leave, and flowering rate). These results suggest that feather hydrolysate prepared using B. pumilius RS7 could successfully be used as alternative biofertilizer, thereby reducing the environmental impact of feather waste from the poultry industry.

  • Researches on industrial crops in Korea before 1962 were concentrated on fiber crops such as cotton, kenaf, hemp, ramie and flax. Then research works on oil crops, sugar crops and other high income crops were followed. However, no land is shared for the production of kenaf, flax, sugar beet, sweet sorghum and sunflower at present in Korea, while the cultivation of cotton, hemp, ramie and mat rush is decreasing continuously to the marginal point. At present researches are emphasized on oil crops such as seasame, peanut and perilla and high income medicinal herbs of which cultivating acreages are increasing. Numerous varieties were released as a result of active breeding works on industrial crops since 1962, i.e. 3 sesame varieties including "Suweon 21", 3 peanut varieties including "Seoduntangkong", and 6 rape varieties including "Yudal" in oil crops, one cotton variety "Mokpo 7", one hemp variety "MS4-1", and one kenaf variety "Suweon 2" in fiber crops, and two stevia varieties "Suweon 2" and "Suweon II" in sugar crops. Quality improvement of rape seeds and development of hybrid rapes utilizing male sterile lines are the most significant results of breeding works, while the establishment of vinyl mulching cultivation of sesame and peanut are the most successful results in agronomic researches during the last 20 years.re the most successful results in agronomic researches during the last 20 years.

  • In this study, we examined the effects of egg yolk powder added to flour dough on the lipid oxidation of fried products during storage. The flour dough containing the egg yolk powder (0, 5, and 10%) was fried in sunflower oil at $180^{\circ}C$ for 90 sec. The fried products were then stored at $60^{\circ}C$ for 9 days in the dark. The lipid oxidation of the fried products was evaluated by fatty acid composition, peroxide values (POV), conjugated dienoic acid (CDA) contents, and thiobarbituric acid (TBA) values. The color and phospholipids (PL) contents of the fried products were also determined by colorimetry and high performance liquid chromatography, respectively. The addition of egg yolk powder to the dough decreased the POV, CDA contents, and TBA values of the fried products during storage. Although POV, CDA contents, and TBA values significantly increased in the products without egg yolk powder during storage, little change was observed in the products with egg yolk powder. The PL contents remained relatively constant in the flied products added with egg yolk powder during storage. The lightness and greenness of the fried products decreased, and the yellowness increased, as the storage time increased. The results clearly indicate that the addition of egg yolk powder to the dough improved the lipid oxidative stability of the fried products during storage in the dark, and the PL in the egg yolk might have contributed to the improvements in lipid oxidative stability.

  • Objective: The present trial was conducted to determine the influence of different dietary fatty acid (omega-3 and omega-6) sources on reproductive performance of female broiler breeders and growth performance and carcass traits of their progeny. Methods: Two hundred and twenty, 25 weeks old Ross-308 male (20) and female (200) broiler breeders were used in the experiment for the period of 6 weeks. All birds were randomly divided into four dietary treatments (containing 2% soybean oil, 2% sunflower oil, 2% flaxseed oil, and 2% fish oil) each with five replicates of one male and ten females. Throughout this experiment hatching performance of broiler breeders, progeny growth performance and carcass parameters were recorded. Results: The results showed that the inclusion of different fatty acid sources in female broiler breeders diet had no significant effects (p>0.05) on number of fertile eggs, post-hatch mortality, and fertility rate. The soybean oil supplemented group had significantly (p<0.05) higher late embryonic mortality compared to other three treatments. Conclusion: It was concluded that inclusion of 2% of different sources of omega-3 and omega-6 fatty acids (especially 2% flax seed oil) in broiler breeders' diet can reduce late embryonic mortality. The other reproductive characteristics of parents and growth and carcass characteristics of progeny remained unaltered by dietary sources of omega-3 and omega-6 fatty acids.

  • Ethnobotanical knowledge on native plants is critical on the conservation and management of biological resources. We investigated traditional knowledge of ethnobotanical uses in the Mt. Gayasan National Park area. Interviews were carried out to 189 residents at 176 places, and verified species and usage information was categorized by taxonomic groups, usage, and used parts. The ethnobotanical species of the regions consisted of a total of 275 taxa in 91 families including 105 cultivars. Sunflower family (Asteraceae) is the most widely used family with 30 taxa (7 cultivars). Rose family (Rosaceae, 25 taxa with 11 cultivars), Bean family (Fabaceae, 15 taxa with 11 cultivars), Grass family (Poaceae, 15 taxa with 10 cultivars), and Lily family (Liliaceae, 14 taxa with 4 cultivars) followed. About 50 taxa belong to the Approved Species for Delivering Overseas designated by Korea Ministry of Environment, and six Korean endemic taxa have been traditionally valuable in the regions. Many cultivated species have been utilized for various purposes accompanied local and native plants. The main usage of the plants are edible (175 taxa) and medicinal (168 taxa). Leaves are most commonly used parts (105 taxa), followed by stems (93 taxa), fruits (73 taxa), roots (55 taxa), and wholes (54 taxa). The study does not only provides examples of traditional uses of native plants, but also facilitates conservation of natural resources and sustainable developments of ethnobotanical knowledge for the contemporary human society.
