Presentations, discussion sessions, and breakout groups were organized by the following conference themes (agenda):
Challenges and Opportunities
Use and Management of Genetic Diversity
Marketing and Exchange of Genetic Resources
Tools for Managing Genetic Diversity
The conference attracted 100 registrants (In-person and virtual live access) representing 9 Countries and 24 U.S. States; industry from 8 Countries and 16 U.S. States; and 20 Universities. Attendees represented breed associations, dairy producers, genetic and genomic companies, university scientists, government agencies, and graduate students.
Consensus was reached on many issues for managing genetic diversity including:
The industry is already addressing inbreeding;
Genetic diversity has declined, and the industry has the responsibility to learn more about genetic diversity and provide scientific answers;
There are substantial gaps in knowledge that require research to better understand and quantify positive and negative impacts of inbreeding; and
The segments of the industry are part of large/global livestock industries and contributions across each industry segment are needed.
The industry still has some differing views of the urgency to mitigate inbreeding and diversity issues; the approaches for mitigation; who pays for solutions (equitable costs across segments), and who regulates.
There has already been follow-up with plans and strategies for collaboration among representatives from industry, academia, and the USDA Agricultural Research Service to address the next steps to manage genetic diversity.
