Cows give birth any age, since a cow is a female bovine that has already had a calf or two.
Heifers, on the other hand, give birth when they're ~24 months of age. Since the gestation period is around 9 months or more (by only a few days), a heifer is able to get bred at around 15 months of age.
A heifer that gives birth at 1 year (12 months) of age is a heifer that was bred way too early. These are what we call "whoopsie" heifers; 9 times out of 10 their pelvic area is still too small at their stage of life for a calf to pass through, and thus must have a Cesarian section done on them. Some heifers may be able to produce enough milk to feed their too-early-calf, but most will have to have theirs bottle raised.

It could mean that a cow is ready to give birth.
No. Cows only give birth to other cows (i.e., calves), not humans.
A "cow" is a cow when that "cow" is a she and she has given birth to at least one calf.
A cow is generally and usually expected to give birth only once a year. However cows can give birth to calves once every 11 months. Occasionally a cow will give birth to a calf 10 months after her previous parturition, but that is quite rare.

A springer or springing cow.
What kind of question is this?? A cow has already given birth, so there's no need to give her anything to make her give birth faster. This is a poorly worded question, and confusing at that.

Baby cows.... Aka Calfs
Yes.

No. A Hereford cow will only give birth to a Hereford-Limousin cross calf if bred to a Limousin bull. Only a Limousin cow can give birth to a Limousin calf--IF she's bred to a Limousin bull. Just like a Hereford cow can only give birth to a Hereford calf if bred to a Hereford bull. Otherwise, she too (referring to the Limousin cow) can give birth to Hereford-Limousin-cross calf if bred to a Hereford bull.
Cows do not give birth every month. They give birth once a year or ever 11 months. As such the question has no merit.
