Castration is best done at this time of year - traditionally after the frosts and before the flies.
Maybe it’s a bit premature to say Spring is here but it certainly feels that way!
Standing castration is the most common and is generally done before 2 years old and for some immature colts, before 3 years old.
However a general anaesthetic is required for older ones due to the serious and real risk of gut herniation or haemorrhage from the testicular arteries in more mature horses. In these cases the cord is tied off with absorbable suture material to prevent these complications. This isn’t melodramatic, as I’ve seen herniated intestines and massive haemorrhage happen!
