CDCB Committees

Dairy producers, industry professionals, and scientists provide input to develop and implement CDCB services and genetic evaluations.

Producer Advisory Committee (PAC)

Dairy farmers appointed by the CDCB Board provide grassroots input for strategy, policy, future priorities, and opportunities through this committee established in 2019.

In 2024, the committee grew from six to nine members, adding diversity in the herds and regions represented. Recent discussion topics have included sustainability metrics, female fertility traits, calving ease, mobility, and more.

Dairy Evaluation Review Team (DERT)

Before the triannual releases in April, August and December, an independent validation process is conducted by genetic industry leaders through objective and confidential early reviews of results. This improves evaluation accuracy by identifying potential issues before public release.
