Thousands of years
ago, human beings began using cattle as a source of food,
clothing material, and transportation. Farmers have different
names for the different kinds of cattle.
A cow is
an adult female bovine that has had a calf (baby cow). Most cows
are either dairy cows or beef cows. Farmers raise dairy cows to
produce the milk that makes products like butter, cheese, and
milk. The most famous kind of dairy cow is the Holstein, which
has a distinct black and white pattern. Holstein cows can
produce up to 18,000 pints (10,000 liters) of milk per year.
Beef cows are raised on a farm and then killed for us to eat.
mostly eat grass, which they digest in stages using four
compartments in their stomach. They also need a lot of water
each day to stay hydrated. Their waste products, called manure,
can be turned into fertilizer by thrifty farmers.
Cows are important
animals in many ancient cultures. In India, cows are sacred.
They were also important symbols of fertility and creation in
Ancient Egypt and Greece.
