The pigs reared at Acy-Romance were small and slight; their skeletons are more like a dog's than a modern pig's.

They must have been very mobile and fast, as described by Strabo, a Greek geographer of the early Common Era: "Their pigs live outside, even at night and are known for their size, strength and rapidity. It is dangerous to approach them if you have no experience of them and they are even dangerous to wolves."

The meat from these animals was consumed in various forms. Some were spit-roasted, shown on the tips of their canines and their limb extremities, and others were cut up and their meat was salted. 

Study of the waste in rubbish pits shows that the trotters and backbones were always thrown away before the head and limbs, which were probably kept for a while for curing. The salt trade played an important role in Gaul's economy, and their cured meats were famous across the Classical world.
