Suckling pig has been considered a delicacy wherever pork was eaten. I even found a Sardinian recipe for boar fetus, so you can't eat it too young.
I copied this from a website about Sardinian food:
Roasted Meat
One of the main forms of Sardinian cooking is roasting. Roasting is a ritual that is almost exclusively reserved to men and on special occasions it is an honor left to the most experienced among the men.
The best known roast is sucking pig which is roasted on a hand crafted spit made of arbutus wood. While the sucking pig is roasting, lard and aromatic grasses such as myrtle, rosemary, laurel and sage are added which flavours the sucking pig.
Another way of roasting which is called mallori de su sabatteri in the language of Nuoro, consists in putting the animals one inside the other in the following way: inside a calf put a goat which in turn contains a sucking pig and keep on inserting an animal into another like a Chinese box.
Buono appetito!
