The black and white Friesian-Holstein is the most common breed of dairy cow on Cornish farms. She can produce 25 to 30 litres of milk a day.
A dairy cow drinks a large quantity of water each day. It can be as much as 100 litres. That’s enough to take a bath in!
How much do you think a cow like this eats? She spends about 6 hours eating every day and can eat 80-100kgs of grass.
Grass is not easy to digest, even when you have four stomachs as cows have. After they have eaten their fill, cows lie down and chew the cud.
Jersey and Guernsey cows were once the most popular breeds on Cornish dairy farms. The Jersey cows are small and give rich creamy milk.

The Guernsey cow gives creamy milk too and is bigger than the Jersey. They are usually brown and white.
Glossary
Chewing the cud – grass that has been chewed and swallowed is bought back up into the mouth and chewed again. This helps the cow to digest the grass.
