Which dairy cow breed produces the greatest volume of milk?

The Holstein-Friesian breed produces the greatest volume of milk of any dairy cow breed.12

Valued globally for their superior productivity, Holsteins significantly outperform other major dairy breeds in annual milk yield. According to a 2021 report from the Council on Dairy Cattle Breeding, the average annual milk production for Holsteins exceeded 11,793 kg (26,000 pounds) per cow, a considerable margin over other breeds such as the Brown Swiss and Jersey. While other breeds may produce milk with higher concentrations of fat and protein, the Holstein's exceptional volume has established it as the dominant breed in the dairy industries of the United States and many other countries.12
