Equine Castration (Gelding)

Equine castration (or gelding) is a common procedure that can either be done on the farm or at the clinic. The following are some guidelines prior to having your horse castrated as well as some after care instructions.

Prior to castration:

  • The horse's tetanus vaccine must be up to date. Needs to be given within the last six months, with the appropriate booster given 3-4 weeks after the initial dose. If the horse has not been vaccinated, it must be done 10-14 days prior to the castration, with a booster required four weeks later.
  • the area where the procedure is performed should be comfortable and familiar to your horse. This will help make the castration easier and make your life easier if there are any post-operative complications, such as infection, etc.
  • The horse should be used to being sprayed with a water bottle at the castration site, as you will be spraying incisions once daily until healed with a wound spray.
  • Have straw or hay available for bedding after surgery.

Possible complications:

  • Bleeding is a concern, especially in the first 24 hours. If it is a steady drip (more then 1 drip per second) or a steady stream lasting more then 15 minutes, call us immediately.
  • Infections may not be evident until days after the surgery. Chronic infection may not be evident for months to years afterwards.
  • Evertration - intestines coming out through castration site is an uncommon, but possible, complication of castrates. Most commonly happens 4-6 hours after the castration, but can occur up to 12 days after the surgery.
  • Complications can be minimized if surgeries are done at  a young age. Mature breeding stallions are at an increased risk for complications.

Post-Operative Care

  1. Keep the horse stall confined for 24 hours post surgery.
  2. Bed the horse on straw to keep savings/sawdust out of the incisions.
  3. Spray the incisions once daily with a wound spray.
  4. If the bleeding has stopped, turnout/exercise in a clean and dry paddock the day following the surgery. If reluctant to walk, encourage gelding to move. The horse should walk to allow drainage and minimize swelling for 20 minutes a day. This should continue for two weeks after the incision is healed.
  5. Swelling tends to be the worst 4-5 days after the surgery. If the gelding is eating and moving well, then do not be concerned.
  6. Males should be kept from the mares for at least 14-30 days following the surgery. Stallion like behaviour may persist following the castration.

Please call our office if you have any questions or concerns or if you see anything protruding from the incision.

Read What Our Clients Say

  • "I wanted to thank you again for your help last Friday. There are many animals on my farm. I love them all but I was particularly fond of little Gabby. It was only a couple weeks ago we saw her rolling in the dirt and so delighted with herself and I remember how she loved to lay on Jeff's chair and bat the tail of our other cat as she walked by. I had hoped she could have experienced more of these joys in her life.
    Your skill in diagnosing and presenting her case and your compassion in helping me understand what was best for Gabby was very much appreciated."
