1. The first scene panning across the feeding pigs was showing the typical feeding stations for piglets. They have the mother in a small cage so she doesn’t get up prematurely or harm any of her children. This isn’t where pigs spend their time all day. When they are without a litter they spend time in pens outside or in a barn.
2. The scene with the piglets. This is the practice of clipping the piglet’s tails. This is common practice, and if this wasn’t done the little pigs would end up getting infections from their tails dragging in mud. It is quick, relatively painless and helps prevent disease. Hell, not doing this would be even more shocking.
3. As for the last scene, the pigs were being pushed with boards into a smaller pathway. This is done to move pigs from the outside to the inside of a location and happens daily (or when there is bad weather). It is just a way of herding animals. I couldn’t tell from the clip, but they could have been headed off to the slaughterhouse, who knows?… NOBODY IS TALKING.

Seriously, using footage and not explaining it to get across your point is downright immoral. It is like showing a child (an uneducated viewer) something hoping for a reaction. Basically how propaganda works.

I couldn’t stop watching it. I needed to know.

And now that I know, I might just stop eating meat.
