• Sommario/riassunto: Agricultural techniques used to increase production of cattle, sheep, and other major species have actually threatened the future genetic diversity of livestock populations, particularly in the Third World. This volume explores the importance of animal genetic diversity and presents a blueprint for national and international efforts to conserve animal genetic resources. It also evaluates genetic techniques useful in conservation programs and provides specific recommendations for establishing data bases and conducting research.
