First of all, hopefully this calf is still alive! You need to give it colostrum immediately. The more you wait the lesser the chance of that calf not only surviving, but growing into a healthy animal. Milk out the mom and tube-feed the calf the milk you get and freeze the rest for later. Get the calf in a warm shelter immediately to get it warmed up (especially at this time of year and if you're in a cold climate). Get a vet out to see why this calf won't get up, because things like mineral deficiencies (i.e., White muscle disease) will weaken a calf and make it too weak to want to get up almost immediately after birth.
A healthy newborn foal should be trying to get up and walk to the mare to nurse in less than an hour. The mare should be nuzzling the foal and licking it, encouraging it to stand to nurse and learn to walk.

It may be humane to put it down. But there are a vast number of reasons why a calf won't get up, and it's best to talk to your veterinarian or get the calf to a large animal vet to diagnose why it won't stand up on its own.
Every muscle in the back of the calf (with the exception of the popliteus) helps to raise you up on your tip toes.
Get it in a warm dry place after it has been born and after you have ensured the calf is alive. Then bottle feed it with colostrum for the first 24 to 36 hours, then slowly wean it of colostrum to replace it with milk replacer. Do this only if the newborn calf is an orphan and you cannot find a serrogate mother to accept it.
The most accurate way to tell the age of your calf is by looking at his front teeth. A newborn calf will have no teeth; a week old calf will only have maybe one or two teeth that have popped up already; a 1 month old calf will have all 8 lower incisors already.
If everything is allright, she'll push her newborn calf up for some air as soon as possible.
calf raises (aka) toe raises are when you stand on the base of your foot and simply raise up as high as you can. Calf raises are good for increasing vertical, muscle strength and speed. some other ways to do calf raises are to stand onto a raised platform such as a step and simply raise up and hold for 3 to 5 seconds.
A newborn calf, just like with a human baby, will be mostly sleeping and getting up to suckle from mom when its hungry or when its mother lets it. A cow will commonly hide her newborn calf in some brush or tall grass for the first week--if she has that choice--while she goes off and grazes, just like a mother deer, moose or elk will.
Usually, a baby Rhino, (calf), will be able to stand up quite steadily about an hour after its born.
Put hip lifters on it to get it to stand up, or put it down if the vet diagnoses the calf as unable to walk again.
