Mares are capable of being bred at 2 or 3, but most people wait a few more years. Some people want the mare to have a successful career to prove she is worthy of reproducing-- others are OK with the mare having proven close relatives.
Breeding always has risks to the mare, and some risks increase as the mare gets older, but with proper care and feeding and appropriate vet exams and care, it is not unreasonable to see mares producing into their 20s.
Edited to add-- colts and fillies are sometimes physically able to be bred as young as 6 to 10 months-- but obviously just because their little bodies are capable does not make it the best choice. 2-4 years is considered the youngest to "safely" breed, with 2 not being acceptable to many people as still too young.
Very good point. I still believe that a stallion should at leat be critiqued by the breed's judges before even siring as a 2/3 year old. AND if it turns out to be a terrible "experiment" crop...really...what happens to the foals? Feedlot? They just become part of the unwanted horse population....sigh...i am not an animal rights activist and I believe that everyone should have the right to do what they want with their animals...but I also believe in common sense
Besides....unless he is stunning quality at a 2/3 year old he shouldn't even have an "experiment" crop of foals...especially for someone inexperienced....JMHO...not trying to ruffle anyone's feathers
