The available local feed sources in the Mekong Delta of Vietnam were estimated by the chemical components such as genetic diversities and nutritional values because of the necessity to conserve and select their valuable traits, and to track the genetic variations. The experiments were also conducted using pigs to evaluate the ultilization of the feed resources on the growth/cost performances and carcass values. However, there has no conservation strategy for either wild species or local landraces. Furthermore, interest in their nutritional values that have been used for animals as the sustainable potential sources of dietary protein and lipid for the future. From the study, it was concluded that local feed materials have large potentials for new disirable pig meat production. The plant and fish feed resources must be intensively conserved, surveyed, evaluated and developed as adaptable production components in the region.
