285 day gestation / 365 days a year = 0.781 years.
That all depends on when they have been bred. A heifer bred at 15 months of age would calve when she's 24 months old. If she's bred later than that, she will always calve 9 months later.
A heifer becomes a cow after she has had her first calf. In other words, you can expect 0 (zero) calves from a heifer over breeding life. When she is a cow, she may have from 1 to 18 calves in her lifetime.
FARTS MAN AHAH
A heifer is young female bovine that has never given birth to a calf.A heifer may be considered a cow if:She successfully gives birth and raises her second calfShe reaches adult maturity at 4 years of ageSome people consider a heifer can become a cow after she gives birth to her first calf, but for many cattle producers she is merely considered a first-calf heifer, not a cow.
An "open" heifer is one that is of breeding age, and able to be bred. A "fresh" heifer is one that has recently given birth. A pregnant heifer is, well, pregnant (that's easy). A springing heifer is one who is nearing the end of her pregnancy, within a few weeks of giving birth. "Dry" is not milking and pregnant. "Close" would indicate 240 days pregnant or more. Note that the term has regional variations on the subtleties of it's meaning; so it's best to use it in the general sense only. For example, in many places "open" just means "not pregnant" and doesn't imply that she's ready to be bred.
30 years
over 25 years i think
WHAT state?
Indefinitely
You can get up to 30 years with no parole. Does not carry a life sentence.
As many as they can. Female cats take nine weeks to carry their pregnancy and after giving birth, they can go into heat again and have more babies.
one, and i believe pregnancy lasts about 4 years, ouch!!!!!
