What are the major dairy cattle breeds?
Seven major breeds of dairy cattle are used for milking. Each breed has advantages and disadvantages.A. Holstein cattle are the most popular breed of dairy cattle. This breed makes up more than 90 percent of the dairy cattle in the United States. The name Holstein is shortened from Holstein-Friesian. The breed came from The Netherlands in the early 1600s. The animals are black and white and very large.

What are the major dairy cattle breeds?
The cows can weigh up to 1,500 pounds, and the bulls up to 2,200 pounds.
The biggest advantage of Holsteins is that, in comparison to other breeds, they produce the largest average amount of milk per cow.
The disadvantage is that although they produce more milk, it is lower in butterfat and protein.
Butterfat
is the fat content of the milk.

The animals are large and have high milk production but with lower butterfat and lower protein than other breeds.
