It could mean anything. Maybe it means that you're going to go into the livestock biz in the future, or else it means the ultimate thing you wish to have sometime in your future.
Mother, being the cow, is the dam. Father, being the bull, is the sire.
A calf-cow or a cow-calf probably refers to those calves that are in between being babies and being adults; or, are at the stage where they can be weaned, since they're too old to be calves, but their too young to be "cows" as well.
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 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."
A cow is a female bovine who has had a calf. She was a calf when she was born, became no longer a calf after she was weaned. Before being put to the bull for the first time she was a heifer and became a cow after she had her first calf.
Cow. Calf came after.
A "daddy cow" is known as the sire. In actuality, cows are mature female bovines, or the "mommy cow," or more properly known as the dam. Bulls are intact/mature male bovines, hence being the "daddy cow" or sire of a calf or next-generation bull, steer, cow or heifer.
A "calf".
A newborn calf, a baby calf or just a calf.
It gives more milk than what it would normally produce for its calf. That's what constitutes a cow for being a dairy cow.
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.
