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.
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.
12 to 15 years of age depending on how well it is looked after.
generally mice only live 4-6 years but 7 is probably the maximum. Many mouses diets depend on how long they live.
Depends on the breed and sex of the calf. Most calves average around 700 to 800 lbs at this age, plus or minus.

Ten.
10,000 because each century is 100 years and if you multiply it by ten (how many centuries) then you get 10,000
Cows are already mature, since they are a mature female bovine that has already had at least one calf. A heifer, on the other hand, reaches sexual maturity at 15 to 20 months of age, and then reaches adulthood at around 3 to 4 years of age. (Most heifers, when they calve at 24 months, are still growing, and will continue to grow for the next 12 months or so while nursing their first calf). Bulls reach adult maturity at around the same age: 3 to 4 years of age.
