Holstein is the most prevalent dairy breed in the U.S. The first Holstein arrived in the U.S. from the Netherlands in 1852. Holsteins, or Holstein-Friesians, are known for their high milk production and larger frame. With high yields, the Holstein quickly gained popularity and currently makes up over 80% of the US dairy population.
