Most equine castrations are done with a technique called an open castration. With this technique the incisions are left open to drain. The incisions will heal within 14—21 days. Regular turnout and exercise during this time is helpful for promoting drainage and decreasing the normal swelling that occurs with all castrations. This procedure is performed on your farm. The horse is put under a short general anesthesia and then laid down in a clean, level area to perform the surgery.
A recent tetanus vaccination (given within the previous three months) is required. The veterinarian will also give antibiotics to the horse on the day of the surgery.
