I belive not! Unless they are an asexual.
A Mares' offspring is called a "Foal".
a foal
A foal.
No more than fillys or any other foal.
Yes, and occasionally mares will swap foals. A mare stealing a foal is often problematic since the mare may not be lactating.
A foal is usually only called a foal for a year. Then they are called yearlings.
Younger mares and mares with good uterine characteristics tend to foal earlier than older mares. With age the uterus tends to be compromised to a greater or lesser degree which slows the development of the foal and increases gestation.
for all mares, they are in foal about 11 months
the mares first lick the foal clean, then the foal will eventually try to stand up. during the first day, the mare and foal will bond.
That depend on the mare.... if she has had a foal before and is having regular cycles it might be OK. If she has never had a foal before its not a good idea. The mares uterus looses its elasticity when they get older. I know of lots of older mares that have had beautiful healthy foals..... but I know of even more old mares that will no longer get in foal. Its really up to your mare and your vet. Good Luck!
Mares can be bred and foal into their mid twenties. Older maiden mares are generally more difficult to get in foal than breeding sound older broodmares that have foaled many timesl
Some mares are already in milk before the foal is born. It is generally only maiden mares or early foaling mares that take more time for their milk to come in.
