No two cows have exactly the same pattern of spots. The cow must be a mother before she will produce milk. A one year old female calf is called a heifer. She weighs between 450 and 500 pounds. A cow has one stomach with four sections.
Cows regurgitate their food and re-chew the cud to help digestion.
A cow spends up to 8 hours a day eating. Milk is rich in protein which helps build your muscles, and calcium which strengthens your bones. If you're between 1 and 12 years old, you should have 3 servings of milk dairy products every day. Teenagers need even more and should have 4 or more servings of dairy foods each day. Adults should have 2 or more servings of dairy per day.
