  • Bacillus polyfermenticus SCD (B. polyfermenticus SCD) has been appropriately used for the therapy of long-term intestinal disorders, because live strains in the form of active endospores can successfully reach the target intestine in humans. B. polyfermenticus SCD produces the most antibiotic-related materials. In the present study, B. polyfermenticus SCD was fermented with soybeans (BPFS) and its probiotic properties were investigated. B. polyfermenticus SCD and BPFS showed a broad spectrum of antimicrobial activity against pathogenic Gram-positive (Streptococcus parauberis, Streptococcus iniae, Lactococcus garviae) and Gram-negative (Flexibacter tractuosus, Vibrio harveyi, Vibrio vulnificus, Vibrio ordalii) bacteria and moulds (Aspergillus niger, Aspergillus oryzae). Sebastes schlegeli were used to examine survival rate and cleanup action by BPFS. Bacterial infection resulted in a mortality of up to 99% in the commercial fodder fed groups. BPFS both enhanced the growth rate of fry by improving their appetite and had cleaned by decreased eutrophication. Therefore, it seems appropriate that BPFS should be developed as an antibiotic replacement, favorable fodder additive, and antifungal material in fish farming systems.

  • Localization of livestock facilities leads to concentration of livestock wastes and subsequent leakage of pollutants into the environment, resulting in public concern about their effects. Nitrogen (N) and phosphorus (P) are the most harmful components of animal manure, but odor from the manure itself and the livestock facilities is also a problem. Improving the nutrient efficiency of the livestock helps to decrease excretion of these environmental contaminants. Pigs and chickens are the main experimental models used in studies to improve nutrient efficiency. Addition of feed supplements and modifying feeding systems to improve nutrient efficiency can result in significant decrease in the N, P, odor and dry matter (DM) weight of manure. Examples of these methods include the following. 1) Addition of synthetic amino acids and reducing protein contents resulted N reductions of 10∼27% in broilers, 18∼35% in chicks and layers, 19∼62% in pigs, and a 9∼43% reduction in odor in pigs. 2) Enzyme supplementation resulted in a 12∼15% reduction in DM weight in broiler manure. 3) Phvtase supplementation resulted in P reductions of 25∼35% in chickens and 20∼60% in pigs. 4) Use of growth promoting substances resulted in a 5∼30% reduction in N and a 53∼56% reduction in odor of pigs. 5) Formulating diets closer to requirements (diet modification) reduced N and P by 10∼15% each in chickens and pigs, and odor by 28∼ 79% in pigs. 6) Phase feeding reduced N and P excretion by chicken and pigs from 10∼33% and 10∼13% each, as well as odor in growing and finishing pigs by 49∼79%. 7) Use of highly digestible raw materials in feed reduced N and P excretion by 5% in chickens and pigs.

  • The HACCP evaluation standards for the meat packaging plant are divided into general scale HACCP evaluation standard and small scale HACCP evaluation standard. There are 69 evaluation items in the general scale HACCP evaluation criteria, of which 54 items in the prerequisite management and 15 items in the HACCP management are included. The number of small scale HACCP evaluation items are 20 and about 29% of the general scale HACCP evaluation items. This may not be enough to produce a safety livestock products for the purpose of implementing the HACCP system due to the nature of the meat packaging plant, which does not show much difference in the production process or method of product depending on the scale. To improve the small scale HACCP evaluation standard, the importance of each item was compared with the small scale HACCP evaluation based on the rate of non-compliance and the severity levels in the general scale HACCP evaluation items. As a result of the study, 8 items were derived from the prerequisites management, 2 items were derived from the HACCP management, and some similar evaluation items were grouped together. Finally, 10 items were added to the 20 items of the existing small scale HACCP evaluation items. In this study, study on the safety management of domestic livestock products are continuously carried out, so that it is possible to provide safety livestock products to consumers and contributes to securing competitiveness of domestic livestock industry.

  • Recently the dairy cow industry have faced environmental issues such as eutrophication, global warming, etc. An LCA was used to quantify the environmental impact of a dairy cow system and to identify key issues contributing to the impact. The system boundary crop cultivation for feeding dairy cow, feed production, rearing and manure management (cradle-to-gate). The functional unit was 1 kg of milk (fat protein corrected milk, FPCM) produced. Rearing and cultivation of feed crops stages in system boundary to the environmental impact of the domestic dairy cow system were dominant issues. Techniques such as suppression of enteric fermentation, improvement of the energy efficiency of farm equipment and apparatuses, management of leachate generated during the crop cultivation, and development of controling the loss of fertilizer during crop production would be necessary for the improvement of the environmental key issues of the dairy cow system.

  • The purpose of this research is to do exploratory analysis on the relationships between demographic characteristics of entrepreneurial candidates and their developmental level of entrepreneurial traits as well as the choice of business field. We analyzed gender, age, and educational level of the entrepreneurial candidates and their developmental level of entrepreneurial traits such as achievement tendencies, degree of awareness, planning skills, sincerity, interpersonal relationship, and problem-solving skills. Industry fields were classified into 4 types: restaurants, retail, services, internet business. Descriptive statistical analyses, logistic regressions, and variance analyses were performed about the sample data gathered from 1,441 persons since the year 2002 to 2014. Males and highly educated above university preferred service industry than restaurant, retail, and internet business. Females preferred internet business, retail, and restaurants than service industry field. The young persons under 20 showed higher probability to choose internet business. The college level and high school graduates preferred retail and restaurants than service industry. The developmental level of entrepreneurial traits were higher in male and highly educated. By this study, we could find the divide between groups with high and low probabilities of failure: restaurants and retail field showed higher failure probability than service industry in the business fields of self-employed. Furthermore, we could identify that entrepreneurial traits also had been developed differently depending on the groups. It is necessary to refrain from entering into the fields with high failure probabilities as well as to provide supporting policies to build the systems and environment to reduce the cases to begin new business without special knowledges and know-hows. The competency development training should be provided in the early stage of start-ups considering their entrepreneurial traits and aptitudes. Not only the assessment of the entrepreneurial traits but also professional counseling from initial stage are necessary.
