Objective:
1. Develop an understanding of population structure for targeted species, conduct surveys of breed populations (census), determine the number of producers raising a breed and their geographic location; synthesize and analyze information about phenotypic performance, breeding value, DNA information, adaptation to environmental conditions for inclusion in the Germplasm Resources Information Network (GRIN) database. 2. Acquire germplasm (semen, embryos, ova and DNA) for storage in the central repository. Coordinate collection and documentation of germplasm. 3. Evaluate, develop and implement cryopreservation protocols for the preservation program. Evaluate acquired germplasm for viability and place test results and accompanying information in the GRIN database. 4. Develop the National Animal Germplasm Program's information system as a component of the GRIN. This information system will provide a critical linkage for genetic preservation and management activities of in-situ and ex-situ populations. 5. Develop, coordinate and assist species committees and the Animal Germplasm Policy Coordinating Committee in setting priorities and procedures for preserving animal germplasm and the management of in-situ resources.

Approach:
The primary mission of the National Animal Germplasm Program (NAGP) is to conserve food animal genetic resources (livestock, poultry and aquatic species) in the U.S. Effective conservation involves understanding and/or use of live animal populations, genetics, cryopreservation and information. NAGP addresses genetic resource issues by the following four elements: 1) Understanding the population dynamics of livestock breeds (both numerically and genetically); 2) Acquiring and storing cryopreserved germplasm (where possible) from food animal species; 3) Evaluating potential viability of germplasm in cryostorage as well as improving the efficacy of cryopreserving germplasm; 4) Building and implementing an Internet-based information system comprised of a relational database and decision support tools; and 5) Executing this national effort not only through personnel directly supported by this project plan but also involving a cadre of industry representatives, university and ARS scientists working across species and disciplines. The NAGP has not been mandated with a typical research mission; rather the focus is to ensure the livestock sector has sufficient genetic diversity to meet growing demands, risks and a changing market place.
