Animal rights group Mercy for Animals released video this week showing the abuse of pigs at an Iowa factory farm.

The types of abuses included mother sows being confined to crates barely larger than their bodies, testicles of piglets being ripped off without painkillers, tails cut off piglets cut off without painkillers, exposed intestines from botched castrations and workers being trained to throw piglets across the room.

Iowa lawmakers have been pushing for an agriculture filming ban.

Warning: The following video is extremely graphic.
