Coloration varies with breed; common colors are black, white, and red/brown, and some breeds are spotted or have mixed colors. [6] Bulls are larger than cows of the same breed by up to a few hundred kilograms. British Hereford cows, for example, weigh 600–800 kg (1,300–1,800 lb), while the bulls weigh 1,000–1,200 kg (2,200–2,600 lb). [7]
Cattle breeds fall into two main types, which are regarded as either two closely related species, or two subspecies of one species.

In that year a breed association, the American Aberdeen-Angus Breeders' Association, was established with 60 members in Chicago, Illinois; the name was shortened to American Angus Association in the 1950s. [2]: 105 [6] Until 1917 both black and red cattle could be registered in the herdbook of the association.
Historical records suggest these cattle were black, and the Friesian cattle at this time were "pure white and light coloured". Crossbreeding may have led to the foundation of the present Holstein-Friesian breed, as the cattle of these two tribes from then are described identically in historical records.
