Accelerate embryo growth
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
11 months but if it is cold they will will go about 1 month longer and some mares will rotinely go a year.
45 The average gestation for a mare can range between 320-370, or about 46 weeks to about 53 weeks.
Mares usually give birth at 4 years. Unless they're water of youth mares. Then it's a little diefferent. Hope that helps :D
If you mean how long are mares in gestation, then 11 months. If you mean how long until a mare can breed again after foaling, I don't really know. The mare goes back into heat usually around two or three weeks after foaling.
A foal is usually only called a foal for a year. Then they are called yearlings.
It depends what you mean by how long are mares, if you mean by how long they live the same as the average horse or pony, how long they are by measurement it varies to which breed they are.
You probably mean "Gestation" and this is the period of time when a mother is carrying her baby.
This is a time in a mares life when she is ready to breed.
Accelerate
yes, you mean turn?
