First, the calf may die if it doesn't get colostrum within an hour or two after birth. Secondly, the mother will simply dry up (stop milk production) if her calf doesn't survive or you don't get the calf to start suckling from his momma.
it should be. or the calf could "get stuck". the vulva will swell prior to giving birth unless the calf comes really early.
Cows and first-calf heifers have four functional teats.
Yes.
No. Heifer calves only have four little nipples/teats where the udder will be after they have their first calf. Heifer calves, when the do become mothers themselves, are no longer considered heifer calves, or a calf at all, but rather a cow or a first-calf heifer. Their udder typically begins to form during the last trimester of pregnancy (if a heifer does indeed get settled after reaching puberty), and will become swollen with milk once her first calf arrives, making her ready and able to give milk after giving birth.
Right after birth, or as soon as the calf is out of the birth canal.
A cankle is a female's swollen ankle whose flesh merges in an unattractive way with that of the calf.
This depends on the cow, actually. Some cows may start lactation right after her calf is born, others (and this may refer to most) will start freshening (producing milk) a few days to even a few weeks prior to giving birth. One of the classic signs that a cow is about to give birth is that her udder and teats start to engorge themselves with milk.
There are really two ways to tell if a cow (or heifer) is a virgin or not. One is by the size of the vulva, and the other by the udder and teats. A virgin cow (a female that has already reached adult maturity at around 3 years of age) that is not pregnant or has never been bred will have a smaller vulva and almost no udder (except for four small teats between the legs). Cows that are not virgins will have a larger, more defined udder and teats and a larger vulva. The reason this is so is because, with the udder, milk needs to be produced in order to raise a calf. Mammary glands in cattle are only developed when the cow or heifer is pregnant: growth of teats also occur to allow for a "better grip" for a calf to suckle on. As for the vulva, they are larger in "experienced" or non-virgin cows because they have been stretched out from having to pass a calf through the birth canal. This stretching is the same in women, and is the very reason why heifers and women who give birth for the first time find it more difficult (and more painful) to give birth than those who have given birth before.
A Pied calf may weigh around 100 lbs at birth.
ya it is go see a doctor

The cow gave birth to a small male calf. We called the calf Sunday.
