Bos taurus


Other Names for Me  

A female cow is just called a cow. A male cow is called a bull. A baby cow is called a calf. Cows are often called cattle.

About Me  

Holstein cows were brought to the U.S. from Europe in the mid-1800s. They are just one of many breeds of cow. Some cows are bred for how much milk they make and some are bred for meat. Holstein Cows make a lot of milk. If milked twice a day, a Holstein cow can give more than 65,000 pounds of milk a year.

Body Traits  

Holstein cows are white with black or brown splotches all over. At birth, they weigh about 90 pounds, but they can grow to 1,500 pounds. They have horns that are often cut off as a calf. Females have large udders for milk production for calves.


Cows are herbivores, eating all plants. They are also ruminants. This means that they can eat dry grasses and digest it with the help of a 4-part stomach. Microorganisms (bacteria and protozoa) in the largest part of the stomach, called the rumen, help break down the dry parts of the grass (cellulose). Then the cow spits up or “regurgitates” the food and chews it again! This is called chewing their “cud” and further helps to break down the tough grass.

What I Provide for People  

Cows provide milk, beef, veal and leather. Cattle have also been used in some places as laborers, pulling carts and plows.
