Say what? Please use some punctuation marks and clarify your question. It's not clear, at least to me.

I see nothing wrong with how your question is phrased. I understand your question. I am in no way a horse expert, but I found a few things. Your best bet would be to consult a vet about this, though. Get a professional opinion from someone who can examine her and give you sound medical advice based on that exam and experience. Question I have a 25 year old mare that is in great shape. She has her regular vet check-ups and is healthy. Is she too old to breed? And when do horses stop cycling. Answer Hi Roger,While a mare can cycle throughout her 20s. Those cycles usually become irregular. An older mare can have more problems getting pregnant and staying pregnant. If your mare has been consistently bred and has not had any issues with foaling or carrying a foal to term then she should be fine to breed. Make sure that you get a full examination from a reproductive Vet prior to breeding her. http://en.allexperts.com/q/Breeding-Horses-3331/breeding-25-year-old.htm Could My Mare Be Too Young Or Too Old To Breed? Mares often go on breeding until late in life, and suffer no ill effects from it. This is certainly true in general of animals that have bred regularly; it is more difficult to get an old mare in foal for the first time. Fillies become sexually mature at around 18 months old, and can foal as two-year olds. However, they are still growing at this age, and pregnancy may hinder their growth. Ideally, mares should not begin breeding until four years of age (to foal at five years), although some are put in foal when they are three. http://www.horses-and-horse-information.com/articles/horse-breeding.shtml Age for breeding - Most mares are able to be breed from their first "heat" cycle, about 18 months of age, up until they no longer have "regular" cycles. Most breeders like to start at age four because the mare is finished growing at this age. Sometimes the mare can breed into her late teens. http://www.howtodothings.com/pets-and-animals/a3585-how-to-breed-horses.html

19 is very old for a mare to foal, especially if it's been a few years since she's had a foal. We used to raise horses and some of our broodmares would continue breeding successfully into the late teens but it's not easy to do and they can lose condition so rapidly. Any problems during pregnancy you can multiply 5 fold at least. I wouldn't do it if you love your horse.
