Scientists wanted to find out how long the animals survived when more than a third of their blood had drained from their bodies.
Medics hope the experiments will help British soldiers in Afghanistan as well as casualties of terror attacks like the July 2005 bombing of the London Underground and a double-decker bus.
In particular these results should help them understand how to control haemorrhaging in bomb blast victims.
These are revolting and unnecessary experiments. Sadly, we are too familiar with the effects of terrorism. It is perfectly possible to find out things we don’t know without blowing up pigs to find out.
