the less bleeding of the cords in way of castrating by torning or turning is caused by the stretching and twisting of the blood vessels during this - so they get closed against the blood flowing, i can imagine.
a clean cut let the whole squarecut of the vessels openfor further bleeding out..
and it will go better, if the animals are castrated when they are young - so they have thinner vessels with less blood flow.
i mean - with us men its the same...
