CDCB Services

CDCB provides premier dairy genetic information services – through the National Cooperator Database, world-class genetic and genomic evaluations, and management performance benchmarks.

Genetic Evaluations

CDCB calculates genetic evaluations for 50 traits and 4 selection indices used by dairy cattle producers worldwide. These U.S. breeding values are presented on six different breed bases, representing the six main dairy breeds in the U.S.

Evaluation Types & Access

CDCB releases evaluations on a weekly, monthly, and triannual basis, based on animal status.

Genomic Evaluations

The U.S. was an early adopter of genomic selection, which revolutionized dairy cattle breeding.

Merit Indices

Lifetime Net Merit is the main genetic selection index in the U.S., combining more than 40 traits.

Individual Traits

U.S. evaluations measure genetic variation for yield, conformation, fertility, health and feed efficiency.

National Cooperator Database

The database managed by CDCB has set the gold standard worldwide, combining an unmatched quantity of phenotypes, genotypes and pedigree data with robust quality standards.

Haplotypes & Genetic Conditions

Haplotype tests are routinely conducted to identify new recessive disorders and track the carrier status of genotyped animals.

Dairy Goat Evaluations

Evaluations for milk, fat, protein, 13 linear type traits, and final score are published for 9 dairy goat breeds, plus crossbred animals from those breeds.

History of Evaluations

U.S. dairy cattle improvement began more than a century ago through research and development in milk recording, genetic evaluation and herd management. Early efforts were led by the U.S. Department of Agriculture along with farmer organizations. In 2013, calculation of U.S. genetic evaluations transferred from USDA to CDCB, with continued collaboration in dairy genetic research.
