Equine castrations are performed on male domestic horses that are not intended for breeding. Ideally castrations should be performed on horses at 1-2 years of age. Horses younger than 1 year of age have very small testicles that are difficult to manipulate during surgery, and horses over 2 years of age have larger testicular blood vessels making haemorrhage a greater complication.

Time of Castration

It is best to castrate horses in the spring, summer or autumn when the weather is mild. Undertaking castrations in winter can be problematic as the cold weather can cause problems with healing post surgery.

Castration Procedure

Castrations can be performed standing (with sedation) or with the horse cast on the ground (under general anaesthetic). Standing castrations require fewer assistants however the technique used is dependent on the surgeon preference.

Post-op care

The scrotal incision in castrated horses is left open to allow drainage. The horse should be stabled after the procedure to allow the sedation to wear off and then turned out after 24hrs to reduce post-op swelling and stiffness. Castrated males can still be fertile for up to 6 weeks after procedure, therefore they should be kept away from mares during this period.
