It’s a discussion that pops up occasionally.I debated putting a similar comment up here yesterday. I know Peter is a very, very well respected vet but I don't follow the comment:
@NickJ - are you able to elaborate at all? There's no pressure in the system once the heart stops beating so by poking knife in its chest all you are doing is letting out a bit of blood that would be in the heart and main vessels in the chest cavity - which would all come out during gralloch anyway. I could never see a mechanism for bloody migrating out of, say, haunches in these circumstances.
As far as I can tell, short of using the sort of kit embalmers use, it doesn’t seem possible to remove blood from the cardiovascular system once the heart stops.
