Equine Castration is the quick and simple process of removing a horse's testicles to avoid the breeding of mares and to improve behavior in a male horse.
The ideal age to castrate a stallion is 1 to 3 years: Old enough that the horse has some basic handling manners to perform anesthesia, surgery, and recovery. But also, not so mature that the stallion's behavior and attributes stick with him long after surgery. We also want to ensure that both testicles are descended for ease of castration. Sometimes, one or both testicles have not descended requiring the horse to be referred to a specialist.
For aftercare, the horse needs to reduce exercise but not completely. Moving around helps reduce swelling considerably. We recommend separating newly gelded horses from mares for a few weeks to avoid any accidental breedings as they can still be fertile for awhile.
