I don't think that's disgusting, it's for learning the structure of an organism, in other words, it's for SCIENCE!
although I do oppose the deliberate over-killing of animals
Anyway, we get our baby pigs from a science laboratory company called BOREAL, they supposedly died of natural causes before they were sold to these companies. they were soaked in chemicals to prevent them from rotting, and then were soaked in water to get the chemicals out
Still there was still lots of fluid in the piggy's stomach (not blood though, they took the blood out of the pigs somehow before the dissection), we had to use paper towels absorb it before any internal organs can be seen
The most disgusting part was when some people tried to cut open the pig's stomach. They probably poked at the wrong place or something, because the stomach suddenly "exploded" and all the fluid and stuff was flying everywhere...
It was both cool and gross... and oh yeah the smell of the pig got absolutely intolerable after a while
