Don’t have any internet info to direct you to for reading. But was lucky enough to work for geneticist, who was old school dirt floor pig farmer . Will have some visual references once I dig through bone yard to find appropriate lower jaws, with cutters to illustrate . Sorry for slow reply, stupid work thing getting in the way. Haven’t been out last 2 nights.....

Welcome to THF Rattlesnake Dan.

We put the skull in a bucket, upside down, with a concrete stepping stone on top to keep the critters from knocking it over. Haven't had any problems. Clean as a whistle after a couple months.

Finally found some good examples for pictures. But full disclosure, I do have animal science background, but I’m not a genetics expert. The man I worked with for a while ran an old school, dirt floor 1500+ breeding sow operation. This was before everything became automated. He had a PhD in genetics. It’s been a while so may not be remembering exactly as he taught me , so if I’m a little off I apologize.

In both pictures you can tell pig on the right has larger cutters, and noticeable difference in overall jaw size. He was just a bigger animal size wise . If you look at them closely, you’ll notice the smaller pig was older. The last molar was fully exsposed . The larger pig on rt, was probably 2 or close to it. The last molar doesn’t usually come in until about then. So the smaller pig was older, and cutters were smaller . It could be genetics, or nutrition, or combo of both. I was told that nutrition only played small roll. But since there’s really no money in commercial pig farming for cutters, there’s not been a whole lot of research into it that I’m aware of. Also it commercial operation, boars gave their needle teeth cut out within a couple days of birth, which greatly retards the growth rate of the replacements. I don’t know why, other than it does because he said so . Hope this is at least a good visual reference for anybody that’s interested.

If I was guessing, the smaller pig was between 3-4 based on lack of wear on molars

We see bigger cutters in different areas. The pigs that look more Russian tend to have bigger cutters. These pigs have a longer snout, longer legs and a mane. Completely different than the pigs we hunt near Menard that look like they just got off the farm, those pigs generally have smaller cutters, even the older ones.

I’m trying to find a picture of the skull he had hanging in his barn . Was an old breeder boar , cutters were long enough that they were curled backwards. Guessing 9-11 in total length outside the gum line . So I don’t know if being from farm/Russian cross etc has much to do with it. I’ve got a call in to him to find out what hybrid crosses he used. Don’t remember, it’s been too long

I CAN'T BELIEVE SOMEONE WOULD ENHANCE THE CUTTERS ON A WALL MOUNT. You are more than likely correct though.

I've hog hunted Wimberley for the last 9 years. When I first got on the property's there were hogs everywhere. I only had permission to trap or bowhunt no guns. I still killed close to 100 hogs per year the first 2years and none had big tusks. Then the numbers took a hard decline. They just disappeared in numbers but with my 8 feeders running year round and 4 traps I could find maybe one or two a month. It's been like that the last 7 years. I kill around 30 per year.
The last few years they all seem to have big tusks. I think maybe the population might have something to do with it but I could be wrong. I've killed some great ones over the years though.

An easier way to get the cutters...Use limb loppers to break the jaw bone and then cut the soft tissue with your pocket knife. Be sure and cut the jaw bone closer to the jaw than the cutter. Those teeth curl into the jaw bone a couple three inches. Bury or boil em to get the cutters out of the jaw.

The cutters are hollow, you'll want to fill them with epoxy so they don't spit over time.
