Like a really evil alien abduction
experience crossed with a Prisoner Of War camp nightmare
Well moneywise i can tell you the pork industry is big business, however industry standards are weak and lack monitoring and compliance capabilities
From a business point of view Its easier than beef or mutton due to them currently having acess to natural light and earth.
I suppose they could dim the lights completely to save on power but the pig to space ratio is providing good value. The cage is also pretty well as small as you could make it.
I suppose we should be thankful that cages aren't stacked on top of each other......
