Stop the cruel practice of male piglet castration without stunning them first in the whole EU!!!

Male piglets are castrated without being stunned first on pig farms/factories, this is a cruel and barbaric practice because the poor piglets fell pains like we humans do, and what´s just as bad´s the fact that no vet does this, the farmer do it themselves, and if the wounds get infected they smash the poor piglets against the walls of the tight boxes they´re kept in to kill them, so this has to be stopped by law in the whole EU!!!
