Since a mature cow is one that already has had a couple of calves already, and since they are only able to have one calf once a year (rarely twins), on average a mature cow will have 10 calves in 10 years.

Are cows old or young?

A breeding herd consists of mother cows no younger than 2 years and bulls are present when necessary to produce calves at the desired time (usually spring when feed is good for milk production) and at a level to have 20 to 30 cows per bull. Calves are sold after weaning to produce income. Bull calves are castrated to become steers to be fattened for slaughter, some heifers are not bred and also are headed to the feedlots. These are stockers and seldom go beyond three years of age. Others are destined to be replacement cows (higher pedigrees are more desirable just as bloodlines are so important in selecting bulls). Mother cows are "retired" when they "skip"...fail to become pregnant...infertile cows are eating valuable feed...this can occur as early as ten years of age...but many cows continue having calves much longer...then the condition of their teeth may result in an inability to maintain body weight wile nursing a calve...they are also sold to slaughter, but not as prime beef! Dairy cattle are for milk production, of course, but their "retirement" age is similar. "Calf" is a generic term for newborn to yearling aged animals whose gender is not readily observable on the "range" just as "foal" is applied to horses until it becomes apparent they are "fillies" or "colts", the terms "heifers"and "bullcalves"are applied until puberty is reached. So the terms "Foals or Colts" and "Calves" are appropiate when a mixed group of young is discussed. After puberty they are stallions or bulls, if male, steers or geldings, if castrated and mares or cows, ready to produce offspring. So "Cows" and "Bulls"can be around two to ten or even twenty years.
