Summary
Global economic pressures are reducing animal genetic resources, prompting increased national conservation efforts. Key strategies include cryopreserved germplasm collections, emphasizing genetic diversity management and understanding breed population dynamics.
Area of Science:
- Animal genetics
- Conservation biology
- Zoology
Background:
- Global economic forces are leading to a contraction of animal genetic resources.
- The 1990s saw a significant increase in national animal genetic resource activities, with the Food and Agriculture Organization of the United Nations playing a key role.
- National conservation programs integrate in situ, ex situ, and information-exchange efforts.
Purpose of the Study:
- To highlight the critical role of cryopreserved germplasm collections in national conservation efforts.
- To emphasize the importance of strategic animal selection for cryopreserved collections to capture rare alleles.
- To identify major challenges in repository development and genetic conservation.
Main Methods:
- Initiation of national programs for animal genetic resource conservation.
- Development of multispecies cryopreserved germplasm collections.
- Focus on selecting animals with minimal genetic relationships for cryopreservation.
Main Results:
- Several countries have established substantial multispecies cryopreserved germplasm collections.
- Animal selection for cryopreservation prioritizes minimizing genetic relationships and capturing rare alleles.
- Identification of key challenges including the need for genetic diversity management across all breeds.
Conclusions:
- Cryopreserved germplasm collections are vital for national conservation of animal genetic resources.
- Effective conservation requires managing genetic diversity in all breeds and understanding in situ population dynamics.
- Repository collections offer long-term value for diverse users and emergency situations.
