  • The Ministry of Environment, Ministry of Agriculture, Fishery and Forestry, and Ministry of Construction, Transportation and Maritime Affairs are in charge of livestock manure management. There are national statistics regarding the livestock industry such as the National Pollution Source Survey, Livestock Statistic Survey, and Livestock-breeding Trend Survey. The current statistical data are focused on the scale of livestock breeding and the production of livestock manure using these data, but it is difficult to establish database due to lack of information. In order to plan relevant policies including management of livestock manure, the government established database systems such as the integrated information system of livestock manure, the integrated system of national infectious animal-disease prevention, and the Sae-ol public administrative system. We have tried to suggest improvements for the comprehensive environmental information system of livestock manure management by detecting problems in each level of the livestock manure life-cycle, making use of the existing systems, and considering the electronic transfer system of livestock manure. The services and functions of this comprehensive system include information of livestock farmers, the production, collection, transportation, and treatment of livestock manure, the area of agricultural land used for livestock manure, the report of approval and results on livestock manure products, management of statistical information, management of civil affairs, and relevant mobile application services. The system is made up of three processes: first, establishment of GIS-based management database of livestock manure; second, establishment of a history management system for livestock manure transactions; and third, development of a water quality assessment system.

  • Organic livestock farming in northern European regions has been expanded with the major animals of large ruminants using pastures and grass silages. Organic livestock farming in some European countries has been in rather short of productivity compared to the conventional livestock farming, however since the gap of productivity between organic and conventional livestock farming has been reported to be reduced when the efficiency of management would improve, organic livestock farming has a potential to develop as a clean livestock farming in the future. We expect that organic livestock farming be propelled to a future model of livestock farming in Korea too. As the schemes for realization of organic livestock farming in Korea, firstly a system for the consistent supply of organic feed should be established. Mountainous areas that represents 63 % of total area of Korea could be utilized for the production of organic forages. Uncultivated rice paddy and upland agricultural field could also be used for this purpose. The active application of organic agricultural by-products such as organic rice straw, organic rice bran and SO forth can be considered for organic livestock farming. Secondly, the replacement of anti-biotics for the management of animal diseases should be developed using natural products. Plants and microbes would be good sources of natural products. Thirdly, the realization of organic livestock farming may require a system for certification of the organic farms and consequently the experts to work on.

  • Transgenic animals are produced primarily by microinjecting exogenous DNA into the male pronuclei of a zygote. Microinjection method for gene transmitting is successful in mice but not efficient in farm animals, limiting it's general utility such as a large scale facility and labour. Based on our finding that sperm cells bind with exogenous DNA, sperm was used as a vector for producing transgenic animals to introduced green fluorescence protein(GFP) gene. (omitted)

  • Hyaluronic acid (HA) is one of the most abundant glycosaminoglycans (GAGs) in the female reproductive tract such as uterine, oviductal and follicular fluids in mouse, pig, cattle and human. CD44 is the principal cell membrane receptor for HA, expressed from the 1-to 8-cell stage in human embryos, during post-implantation mouse and bovine embryogenesis and on the surface of differentiated embryonic stem cells.
