Council on Dairy Cattle Breeding

The Council on Dairy Cattle Breeding is the main gear of the U.S. dairy cattle genetic engine.

CDCB aggregates dairy cattle data to calculate and distribute the national genetic evaluations and genomic predictions. These results are powered by the national cooperator database managed by CDCB – the world’s largest animal database that integrates genomic information and more than 80 years of recorded U.S. dairy animal performance.

Collaboration at the Core

The CDCB is a collaboration between four sectors of U.S. dairy: Dairy Records Providers, Dairy Records Processing Centers, National Association of Animal Breeders and Purebred Dairy Cattle Association. To benefit dairy producers worldwide, CDCB cooperates with several global partners in research and data exchange.

Vision, Mission and Core Values

CDCB Mission

To drive global dairy cattle improvement by using a collaborative database to deliver state-of-the-art genetic merit and performance assessments for herd decision making.

CDCB Vision

To be the leading source of genetic information for dairy improvement.

CDCB Core Value

Providing premier dairy genetic information services and industry collaboration.

CDCB Values






Research Partnership with USDA

The United States Department of Agriculture (USDA) plays a critical role in dairy genetic research and evaluations. This unique public-private partnership is foundational to the success of the U.S. system.

USDA is the federal department that provides leadership on agriculture, food and related topics based on public policy and the best available science. World-renowned scientists at USDA’s Agricultural Research Service (ARS) and Animal Genomics and Improvement Laboratory (AGIL) perform rigorous research to develop and test new genetic and genomic methodologies. This research supports top-quality evaluations, data integrity and implementation of technology and new scientific learnings.

Today, USDA AGIL focuses on research. Until 2013, USDA also provided service to manage the U.S. database and genetic evaluations. In 2013, CDCB assumed full responsibility for the national cooperator database and genetic evaluations.
