castrations are dangerous, we just do them so much we take it for granted. we had a scare with a mature stallion being gelded this year. he took a long time come round and was crashing round stable for 30 mins with 2 adult men trying to hold him (he was 11hh) and ended up very cut and bruised.
everyones heart was racing, and im pretty sure the vets were s****g themselves incase he conked out, cos i certainly was.
sorry to hear bout the ram. i presume he was castrated late as he had breeding potential?
