The first U.S. Holstein sires were genotyped in 2008. After 7 years, the 1 millionth genotype was added to the U.S. database. Since then, the database has grown exponentially – currently increasing by 1 million genotypes every 7 to 8 months. The milestone of 10 million genotypes in the National Cooperator Database was recorded on December 14, 2024.
The surge of genotypes has been propelled by adoption of female genotyping. Genomic evaluations are important tools for mating, culling and herd management decisions in dairy herds worldwide.
