at what age does a mare go out of estrus for good???

dumasgirl is asking questions in health about mares-i could not find a difinative answer on this. in one article they said an 18 year mare may need extra hormones to breed-and why would anyone breed an 18 year old???? so the cycle must slow then stop like other mamals??/

A lot of it depends on the individual horse and what it has been used for.

A maiden mare will normally have a difficult time at 18 to "take". But, if the mare has been bred on a (semi)regular basis at 18 there is no problem breeding them. (generally) I have bred older mares, but you have to make extra sure that their food intake is quality and sometimes help them along with probiotics so that the dam and foal get all of it's nutrients. And continue that nutrition while foal is on the dam.

There are some tb mares that are still breeding in their 20's the oldest one was 26yrs That I know of. So I would have to say that It definitely depends on the individual horse.

These are horses on a few farms that my boyfriend works at. He is the breeding manager.

I want to add that I do NOT recommend breeding the older maiden mare. Too many complications.
