How long can a stallion produce babies. At what age do they stop or slow down? The reason for this question is I have found one and he's an old guy, just didn't know if he would be able to produce for very long. Thanks for your time.
You could get a vet to do a sperm count and see if he's not 'shooting blanks'. That's the most definate way to tell if a stallion can still breed. It depends on the stallion whether they can still breed sucessfully. I have known stallions to still be breeding at 30 or so. These stallions only breed very few mares a year to save the stress on thier bodies. Artifitial insemination is also sometimes used if they stallion can't mount comfortabely.
He's pretty old. Are you planning on buying him for breeding purposes? If so, personally, I would pass. Even if his sperm is good, he doesn't have very many (if any) breeding years left. It is physically very hard on a stallion to breed. Even if everything is ok, he should breed no more than 3 mares per season.
If your thinking of breeding to him, as for a sperm count and motility report. No use putting them through a breeding if it's not going to take. I would say consider AI but, that decreases the chance of a mare "taking" even with a young virle stallion. Sorry.
