Holstein Cows are large in size, featuring white coloring with black or red large spots. Calves weigh around 90 pounds, and mature species reach 1500 pounds and about 58 inches tall at the shoulder. The breed originated in the Rhine Delta region about 2,000 years ago. Original species were introduced in the region by Batavian and Friesian tribesmen, who settled there at that time. Those Holstein-to-be cows were either black or white in color.
