A object could be in it's hoof. Alot of times adult cows or older calves will step on the calf when it's laying down. If the calf is in mud alot they sometimes get foot rot. May not be getting enough milk & is to weak to stand.
Yes, it could be the cause, especially in older people. But there could be other causes as well. If you still have it after a week, see your doctor.
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.
On rare occasions, yes.
As long as the cow thinks it is necessary to hide that calf. Usually a cow will hide her calf for a week or two after birth until the calf is strong enough to be up, running and playing with the other calves.
Baby giraffes are called calves. A calf can stand and walk about an hour after it is born, and it begins exploring vegetation within a week.
depends... did you feed it during that first week?
A calf's first teeth often erupts in the womb a week or a few days before birth. These milk teeth are often seen to help a calf nurse.
Could be a number of reasons: lice, ringworm (a type of dermal fungi), mange, etc.
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.
No. Get the vet out to take a look at him.
because your shampoo is not enough for fighting dundruff
Yes, if by "dry teat" you mean completely stop milking her. This way she has (hopefully) enough time to produce colostrum for her calf. But, you should've dried her up 7 weeks ago to lessen the stress on her when she's in the drying up process.
