Which animal do we need most?Dogs?Horses?No!The answer to the question is cows.Why cows?Cows give us milk.And milk is one of our most important kinds of food.Suppose that all the milk cows make in one year were put into bottles.And suppose these bottles were put side by side.Theline of bottles would go all around the world 400 times.That is a lot ofmilk,less than half of it is used for drinking and cooking.Most of itis used to make butter cheese,ice cream and many other things.It takes many cows to give us that much milk.But not as many as it used to.A cow used to give only about 1,500 quarts of milk a year.Now a fine cow may give more than 3,000 quarts in a year.Why do cows give more milk today?Now farmers have better cows.The cows get better care and better food.
