The wild boars are represented as the primary food for the village (except for Unhygienix's fish, and the fish from the nearby sea)
Obelix has a special attraction to them as he will always eat them when there is an opportunity. Sometimes chief Vitalstatistix is referred to as a "fat old boar" by his wife Impedimenta. At the end of every book, the boars are the main delicaciees served at the banquet.
The wild boars have however learned how to escape Obelix's hunger: by running into a Roman patrol, which will immediately mean that our heroes will be too busy with the Romans and will not bother the boars for some time, time that the boars will use to flee.
