More than 7 million genotypes reside in the CDCB database – with the 7M milestone recorded December 19, 2022.

The first U.S. Holstein sires were genotyped in 2008. In the first 7 years, 1 million genotypes were submitted. Since then, the database has grown exponentially with 6 million genotypes added in 8 years.

Among all genotypes at CDCB, 92% are female. Genomic evaluations have become a valuable tool for mating, culling and management decisions worldwide. In 2022, 95% of the genotypes submitted to CDCB were female. 87% of the genotypes are Holstein, 12% are Jersey, and 1% are other dairy breeds. As of December 2022, 73 countries have submitted genotypes to CDCB.

As the world’s largest animal database, this set of dairy phenotypic and genotypic information was hosted by USDA AGIL* and has been managed by CDCB since 2013. Learn more at https://uscdcb.com/database/.
