Description: Holstein cattle (also known as Holstein-Friesian cattle or Friesian cattle) is a breed of cattle known today as the world''s highest production dairy animal. Originating in Europe, Holsteins were bred in what is now the Netherlands and more specifically in the two northern provinces of North Holland and Friesland. The animals were the regional cattle of the Batavians and Frisians, two tribes who settled in the coastal Rhine region around 2,000 years ago. The Dutch breeders bred and oversaw the development of the breed with the aim of obtaining animals which would make best use of grass, the area''s most abundant resource. The result, over the centuries, was an efficient, high-producing black-and-white dairy cow. It is black and white due to artificial selection by the breeders. Holstein have very distinctive markings and outstanding milk production. They are large, black and white marked animals that can be anywhere from mostly black to mostly white, or half and half. They can also be red and white. The expression of red colour replacing the black in Holsteins is a function of a recessive gene. Size: A healthy calf weighs 40 to 45 kg or more at birth. A mature Holstein cow typically weighs 580 kg, and stands 147 cm (58 inches) tall at the shoulder. Holstein heifers should be bred by 15 months of age, when they weigh over 360 kg Generally, breeders aim for Holstein heifers to calve for the first time between 23 and 26 months of age. Gestation period is about nine and a half months. Perhaps the most famous Holstein was Pauline Wayne who served from 1910 to 1913 as the official presidential pet to the 27th President of the United States, President William Howard Taft. Pauline Wayne lived and grazed on the White House lawn and provided milk for the first family. Pauline Wayne was the last presidential pet cow.
