Bacon is produced from 'baconers,' pork is produced from 'yes you guessed it' these are pigs between 120 and 140 lbs in weight. Bacon pigs are larger older pigs specially raised but not a special breed. To make a large pig economically worthwhile it has to be fed on a cheaper diet otherwise the bacon would be too expensive. Old breeding sows and boars are made into sausages and pork pies, where the texture and flavour of the meat can be blended and mixed with other products to make it more acceptable.
