Her reproductive organs are sugically removed by a veterinarian. The process of putting her under and waking her up is complex as, unlike cats or dogs, if she's under too long she can bloat and die because of the pressure the rumen exerts on the lungs and chest diaphragm when she's down for a long period. But, when she is under anaesthesia, the vet has to cut her open on the right side (the left side is where the rumen is), cut off the membrane and blood vessels and nerves that connect the uterine tract with the rest of her body, and cut the uterus away from the cervix. Clamps have to be used to crush the blood vessels and minimize/prevent blood loss. Other clamps are used to hold on to the uterine horns so that it makes it easier to keep track of what the vet surgeon is removing. Once the repro tract is removed, the vet has to suture up the open gap that connected the uterus to the cervix, then suture up the opening in the heifer's side; first the membrane holding the viscera, then the muscle membrane, and finally the skin.
All in all, it's a very expensive and time-consuming process, and it's not worth doing when you can mix a hormone with the feed that deters from the heifers going into heat every 21 days in the feedlot when you got over 1000 heifers to feed for slaughter.
spaying is the surgical process of neutering a female animal by removing the reproductive organs (ovaries, uterus, and fallopian tubes)
The freshening of a heifer is used to mean the process of a cow beginning to give its milk through its udders.
You could call it a heifer, or a twin heifer if the sibling is also a heifer, or a freemartin if the heifer's sib is a bull calf.
Cow, first-calf heifer, bred heifer, heifer, heifer calf or spayed heifer. See the related question below.
An unpregnant heifer.
No. Spaying and neutering are irreversible procedures.
The gender of a heifer is female.
A springing heifer is a heifer who is within a few weeks of delivering her first calf.
It's the name for a heifer that has had her first calf and is currently raising her first calf. It's also a name for a heifer that came from a heifer or cow that was that heifer or cow's first calf.
Like this:"The farmer had a prized heifer in the cattle shed.""The heifer was bred by the herd bull yesterday.""The cow gave birth to a heifer calf!""Those blasted heifers got out again!!"
That all depends on the age of the heifer. The older the heifer, the heavier she'll be.
A heifer is a young female cow.
