Which breed of dairy cows originated in Holland and is America's most popular breed?

The Holstein breed of dairy cows is recognized as having originated in Holland and has become the most popular breed in the United States. Holsteins are easily identifiable by their distinctive black-and-white color pattern and are primarily valued for their high milk production capabilities. They typically produce a large quantity of milk compared to other breeds, which has contributed to their prominence in the dairy industry in America. Their efficiency and ability to produce milk consistently have made them the preferred choice for many dairy farmers seeking to maximize production.

The Jersey, Guernsey, and Ayrshire breeds, while also notable in dairy farming, do not match the sheer volume of milk produced by Holsteins and are generally less prevalent in American dairy operations. Each of those breeds has unique traits and milk qualities, but none has reached the level of ubiquity and production efficiency that Holsteins have achieved in the U.S. dairy sector.
