Holstein Friesians (often shortened as Friesians) are a breed of cattle known today as the world’s highest-production dairy animals. Originating in Europe, Friesians were bred in what is now the Netherlands and more specifically in the two northern provinces of North Holland and Friesland, and northern Germany, more specifically what is now Schleswig-Holstein Germany. The animals were the regional cattle of the Frisians and the Saxons. The Dutch breeders bred and oversaw the development of the breed with the goal of obtaining animals that could best use grass, the area’s most abundant resource. Over the centuries, the result was a high-producing, black-and-white dairy cow. It is black and white due to artificial selection by the breeders.
