I think the relevant question is: if you were the pig, would you choose the experiment over being treated as in the food industry?

Eating is a basic necessity for life, scientific experiments are not; you can eat plants instead, too.

I understand what you're saying but it's pretty much impossible to be scientific in biology or medicine without animal testing.

Fair enough, but then it would be hypocritical to take advantage of pretty much any modern medicine. All drugs and procedures were tested on animals, as well as biological research.
