Cattle have served humanity since prehistoric(史前)days as beasts of burden and as supplier of leather,meat,and milk.Some of the earliest written records concern the sale of cattle.These valuable animals are unusual in that they do not have front teeth in their upper jaw.Instead they chew with their back teeth and gums(齿龈).Cows swallow their foodquickly and store it in the fat stomach or rumen,the first of the four compartments in the stomachs.Later the food passed into the second stomach or reticulum where it is rolled into little balls or cuds.While resting,cows cough up these cuds and chew them more thoroughly.This time the food passes into the third and then the fourth stomach,where digestion takes place.Bacteria in cow’s stomach aid in digesting the cellulose in terms of grass or hay.

Over one hundred million head of cattle are raised in the United States.Dairy cattle produce more than fifteen and one-half bllion gallons of milk every year.Although dairy

cattle are bred primarily to produce milk,about half the beef used in United States comes from dairy breeds.This is because when dry(no longer producing milk)they fatten quickly and produce high-quality beef.
