My mare was bred at 11, as a maiden, delivered a healthy filly without complications at 12. No problems, she read the textbook on foaling, had no issues, and filly was actually 3 days 'early'.
I personally would not breed a mare, as a maiden, over 15. That's just my personal opinion based on my vets opinions and what I have read/researched. A seasoned broodmare can foal well into their 20s without complications. And alot of it isnt necessarily the foaling part, but more along the lines of 'getting in foal'. A 45 year old woman is going to have a more difficult time getting pregnant than a 25 year old.
There is a 'prime' for every horse, and its going to vary depending on the individual horse.
Breeding is stressful, and there is always the chance that something could go wrong. You just have to make that decision that if something goes wrong, youll be able to live with the results.
And make sure the stallion you choose isnt just 'joe stud' down the road. Make sure he compliments your mare, has a good disposition, conformation and is a proven producer/has a good record himself. Posted via Mobile Device
