Pig altruism: Is it real?

[chickenlover22345]

Do pigs really display altruism as in this video? Is this video authentic or not? Why are a family of pigs pushing what looks like to be a dying/dead fish back into the water? I am curious.

It appears the pigs are pushing a potential predator away to me. They have piglets, so looks more like protection, not altruism. Most pigs would probably just eat that fish.

Looks to me like they were checking it out to eat it.
I've never seen anything out of my pigs to think they would do anything like the video implies.
