Genotypes in National Cooperator Database

A remarkable milestone – 10 million animal genotypes in the National Cooperator Database – was recorded on December 14 as 2024 was winding down.

After the first U.S. Holstein sires were genotyped in 2008, it took seven years to grow to 1 million genotypes. Now, the database has grown exponentially with 1 million genotypes added in the seven months from May to December 2024. This feat is possible through collaboration between the U.S. and global partners, and among dairy producers, genotyping labs, nominating organizations, international partners, CDCB, and the USDA Animal Genomics and Improvement Laboratory (AGIL).

The National Cooperator Database is the engine that helps breed better cows worldwide, through male and female genetic evaluations, national benchmarking, and independent research to improve genetics and herd management.

The database is founded on more than 80 years of recorded U.S. dairy animal performance – or phenotypic – data and now integrates 17 years of animal genotypes. The 100 millionth animal linked to phenotypic records was recorded in the database in 2024. More than 10,000 herds and 60-plus organizations contribute quality animal data into the National Cooperator Database, which was established by USDA and has been managed by CDCB since 2013.
