Pigs

Matthew Evans is a free-range pig farmer, but 90% of pigs we eat come from intensive farms, so Matthew sets out to find out how the majority of pigs are farmed in Australia. When Matthew visits an intensive farm, he discovers it is a complex business. Most farmers use small cages called farrowing crates, which are just big enough for a sow to lie down while her piglets suckle. They are designed to protect the piglets from being crushed by the sow, which happens more regularly on free-range farms. But is the confinement of the sow worth it for the sake of keeping more piglets alive?
