About a couple of minutes after being born.
Not on their hind legs, no. They can stand (though for short periods at a time) on their four stout but short legs.
If you are finding that your legs get so numb that you are unable to stand, you should see a doctor. It is normal to get numb legs from sitting for long periods of time but you should be able to stand up.
An orphan calf will defecate at any time. A newborn calf tends to defecate a couple hours after he has first suckled, since milk is nature's way to encourage a calf to have his first bowel movements.
You get a throbbing pain in your leg sometimes when you cross your legs because you are cutting off the blood supply to your calf muscles. It only occurs occasionally because you must not be pressing on the supplying artery each time. It would seem that not the crossing your legs might be a good idea.
Most often a calf's mother is referred to as the dam of the calf, or more commonly, a cow. If it's a heifer that has had a calf for the first time, some folks like to call her a first-calf heifer.
No! It is normal for BOTH legs to come out at the same time, not one at a time. One at a time has potential for the calf's elbows to lock up, making it difficult for the cow to pass the calf. When that happens you need to go into the cow, push the calf back and then pull the leg that is back too much to the full extension, or as full extension as the other leg is positioned. Then you can pull the calf out.
She can also be known as a heifer calf, heifer yearling (if she is a year old), or first time heifer (if she has given birth to her first calf).
Generally on four legs. Upright posture is not for moving.
Most of the time the back legs start growing first. I have raised a couple hundred tadpoles, and I think every time the back legs were first.
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.
When she is a baby she will be called a heifer calf, at a year old-Yearling heifer, once she has her first calf-First time heifer, then finally after the second offspring is born she is a cow.
A baby camel (calf) takes 30 mins to get up and walk but an hour is a perfectly acceptable time.
