Antibiotics and NSAIDs may be given by your veterinarian. Recovering horses should be held in a stall or small paddock for up to 24 hours. This is to ensure adequate clotting.

The day after routine castration, the horse should start trotting for 15 to 20 minutes twice a day. This will help limit swelling and stimulate post-surgical fluid drainage. This exercise should continue for two weeks or until the surgical site has healed. Gelded horses should be kept separate from mares for 14-to-30 days post-surgery, as there is still viable semen in the remaining reproductive tract.

If the site does not heal or there is excessive swelling, or the horse is not acting normally, contact your veterinarian immediately.
