Journey to 8 Million Genotypes
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 more than 1 million genotypes per year. The milestone of eight million genotypes in the National Cooperator Database was recorded on August 31, 2023.
Growth of Genotyped Animals
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.
