Preservation, distribution and share of regional genetic resources are one of the hot topics of international debates. Korean government under National Institute of Animal Science (NIAS) supervision made a law that initiated national management system of livestock genetic resources in agriculture and fishery (July, 2012). NIAS preserve domestic livestock genetic sources of Chikso (Korean brindle cattle), Heugu (Korea black cattle), native pig and native chicken under the strategies of multiple place guardians to keep these minor animals from getting extinct through various reasons. A total of around 3,300 animals are under protection currently. Around 70,000 germ cells of Chikso, Heugu, native goat, etc, are stored by cryopreservation method. Moreover,around 30,000 samples of whole blood and DNA are stored in deep freezers. NIAS also constructed Animal Genetic Resource Information Management System (AGRIMS) and stored information including the phenotypes and genotypes of livestock genetic resources. We also have built companionships with nine provincial livestock institutes and two universities regarding rare livestock animal management since 2008. These companion organizations have around 16,000 animals of 11 breeds in their custody. Internationally, we keep on registering these breeds on FAO and Domestic Animal Diversity Information System (DAD-IS) database systems. Recently we updated registration of 24 breeds of six species such as Chikso, Chookjin Chamdon, Ginkkoridak, Jindo, etc.

This study conducted a laboratory simulation using artificial and natural rainfall in order to investigate the runoff characteristics of livestock resources through the analysis of the surface runoff water and infiltration water by rainfall intensity and fertilization level. Cattle manure and pig liquid fertilizer was used as livestock resource. As a result of this study, it was observed that the surface runoff occurred over 32 mm/hr rainfall intensity, and flow rate of the surface runoff water and the runoff ratio of contaminant parameters from livestock resource was increased, as rainfall intensity was stronger. With doubled fertilization level, T-N increased in compost and the amount of CODMn runoff also considerably increased in liquefied fertilizer. In the case of natural rainfall, the runoff ratio of T-P clearly increased in compost and the T-N of final surface runoff ratio in compost and liquefied fertilizer was ranged from 0.13047 to 0.13623 with stronger rainfall intensity.
