If I was a scientist and a piggie died as part of an experiment or whatever. I would do my best to eat the piggie and not let any part of it end up in the trash and going to waste.
Citation needed on this one. I'm curious.
If they mean as in provides many kind of nutrition, it is still false as it is mostly fat and protein. It is quite homogenous to be called nutritious.
They stick a metal rod, that's been frozen in liquid nitrogen, into the piggy's heart.
This kills the heart cells.
Then they stuff the piggy into an MRI machine and take a picture of its heart -- because an alive piggy's heart beats and makes the picture blurry.
Then the scientists get a pretty picture on their computers and high-five one another.
Success, they all think: "mission accomplished. Funding secured."
