The name of a baby cow is a Calf
The baby is called a calf and mother is a cow. Together they are called a cow-calf pair, or "mom and baby."
No they don't. Besides, two cows that mate cannot produce offspring. Either one or the other has to be a bull, not another cow. See, cow + bull = calf. Besides, blue cattle don't exist, if you're not including the blue roan colouration. If you are, then a blue-roan cow bred to a red bull would likely produce a black calf, or even a speckled-roan calf. But never a purple calf.
Because it's less work to have a calf-turned adult cow, bull, steer or heifer, forage on its own than to give it milk every day. Besides, the cow that is close to calving can't afford to have milk for both her older offspring and her new calf, so the older calf has to be weaned.
Cow. Calf came after.
A "calf".
A newborn calf, a baby calf or just a calf.
The best thing you can do is to skin the dead calf of that beef cow's, and drape it over the orphan calf's body so that you trick the cow into thinking that that calf is hers. But this will only work if you have that cow's dead calf on hand and not if that cow doesn't have a calf or if you're wanting to put another calf on that cow. Other tricks include smearing cod liver oil or perfume or some other strong-smelling solution that's not poisonous to the cow nor calf over the cow's nose and all over the back and head of the calf, putting a dog in with the cow and the calf, etc.
A young cow, in the sense of it being female, is called a heifer. Heifers remain so until they have had a calf. However in the more general sense, a young "cow" is called a calf.
The offspring of a cow is referred to as a calf. A heifer calf is a female calf, a bull calf is an intact male calf, and a steer calf is a castrated male calf (castrated after birth).
