Breeding

Gelding

The bottom line is that I think unless you have a good justification, all male horses should be gelded UNLESS they are exceptional. It is the right and kind thing to do. I also believe there is no physiological reason to leave a horse as a colt longer than necessary in the hope he will grow bigger and stronger. In my view, it is best to geld horses after weaning and before puberty for the sake of their social development and mental maturity.
