Dear Chemarq,
Sense we in the US don't have "pure" European/Russian boar, as such, to hunt in the wild, I'll keep my comments to our ferral hogs. I hunt mainly in the Southeast US. The average weight of a hog is about 150 pounds (68kg) with a few up to 400 to 500 pounds (181 to 227kg).
A ferral hog female can birth up to three times a year with a litter size of up to ten and rarely twelve piglets. On averge they deliver twice a year with eight to ten to a litter. As you can see they can overpopulate an area rather quickly. They can create damage to crops, orchards, and the wilds, if allowed (what's to stop them?!?!)
Most states list them as pests, so they can be hunted year-round. Some states allow night hunting.
Hogs/pigs/wilf boar are very intelligent, cunning, and FAST learners. They are a worthy animal to hunt no matter where you find them.
Yes, we hunters DO give great value to our pigs, but with their easily over populating an area and the dammage they can inflict on farm land and wild areas alike, the state wildlife agencies have, for the most part, declared them pests, albeit worthy pests.
I value them, probably more than most, as I know what they are capable of.
Yours,
Norman
