What age should I castrate my horse?

We are often asked what is the best age to castrate colts.
Providing both testicles have descended, colts can normally be castrated anywhere from 5 months – 2 years old. Any younger and the testicles may not have descended or be developed enough to remove, and any older than that and the risk of complications from bleeding can be higher (although of course, horses can still be castrated at any age).

In general, castrations can be performed in the field (meaning we can do the procedure at your yard). Both testicles are removed using an instrument called an emasculator. After the horse has recovered from anaesthesia, they are often better being able to move about, which reduces post-surgical swelling. Therefore the best time for doing the procedure is in late autumn or winter, as there will be fewer flies present, enabling the incisions to heal faster.
