What purpose do pigs serve other than for food? I mean cows give us milk, sheep - wool, chickens - eggs.......no offence to all the vegetarians/vegans out there but, can anybody else think of anything?
Pigskin. Bladders for Court Jesters and Morris Men ( no, not spare part surgery; to tie on a stick to arse about with). Ears to make into dog-chews.
'Only bit of a pig you can't use is the squeak', they say here in East Anglia. Mind, I shouldn't investigate what they mean by that; they have interesting habits round Stiffkey way.
They are well suited for organ transplantation to humans. Their organs are the same size and have the same plumbing as ours. They have been used for this purpose and experiments continue.
Not the most common purpose ( as far as I know ) and not to everyones taste ( certainly not mine ), but they are used in acts of bestiality.( not by me )
