In the EU about 150 million pigs are bred by 2 million farmers.
This is the image of one of the farms. 30 thousand animals, locked in a few pigpens. The image of the never-ending cycle of insemination, pregnancy, labor, feeding the young in farrowing crates, castration, tail docking, separating males for the fattening process from the ones going to a slaughterhouse, and from sows who stay there to begin another cycle. To have the next piglets.
And so the cycle repeats.
