There are a lot of vegetables that used to be given to pigs in the north, some of which were grown by themselves and some of which were cut outside, but now they are basically grown by themselves. And pigs do not eat vegetables like human beings. Usually people will feed the pigs with vegetables they can't eat, such as pumpkins, winter squash, cabbage, etc. In the old days, when the pigs were poorer or the harvests were better, the pigs were given more vegetables. In the old days, when they were poor or had a bad harvest, they could dig up wild vegetables and give them to the pigs to eat.
