The Close Up story could hardly be described as balanced.
Many commercial pig farmers in New Zealand use farrowing stalls. Pigs are carnivorous cannibals. The frames are designed to stop sows either rolling on top of and crushing their young or eating them. The cages minimise piglet death and enhance their wellbeing. In many cases the sow only stays in the cage until the piglets are weaned.
As for the squealing, anybody who has ever been into a commercial piggery generally knows that pigs often associate the presence of humans with food. Once one starts squealing, they all start. It's deafening and only stops once the last pig starts eating.
Chewing at the bars demonstrating psychological trauma or distress? Pigs are inveterate gnawrers. The will chew at most things they encounter. Chewing causes salivation (foaming). If you think that's bad you should see the extent of foam at mating time.
That said, there are some commercial pig farmers whose animal husbandry practices leave much to be desired. That does not unilaterally make farrowing stalls a bad thing.
SAFE is run by political vegans. Any of their claims need to be taken with several grains of salt as their aim is to sensationalise.
