What is a breed?
The classic definition of a "breed" is usually stated as a variation of this statement.
Animals that, through selection and breeding, have come to resemble one another and pass those traits uniformly to their offspring.
The Holstein cow originated in Europe. The major historical developement of this breed occured in what is now the Holland and more specifically in the two northern provices of North Holland and Friesland which lay on either side of the Zuider Zee. The original stock were the black animals and white animals of the Batavians and Friesians, migrant European tribes who settled in the Rhine Delta region about 2,000 years ago.
Dutch Belted
The Dutch Belted breed is, according to records, the only belted breed of cattle tracing back directly to the original belted or "canvassed" cattle which were described in Switzerland and Austria.
traits
A genetically determined characteristic or condition. Traits may be physical, such as hair color or leaf shape, or they may be behavioral, such as nesting in birds and burrowing in rodents. Traits typically result from the combined action of several genes, though some traits are expressed by a single gene.
