I visited The Herbfarm's Mangalitsas today and took the photos below.

That thing on the left looks like it belongs in a zoo. It is a hairy and wet creature.

The newest arrivals (right) have gotten a lot bigger since
they arrived. Head Gardener and Herdsman Bill Vingelen has them on organic hog mash, as per the instructions of Executive Chef Keith Luce.
On the far left there's a Mangalitsa-Berkshire cross. He's nearly as big as the 16 month-old purebred Mangalitsa, despite being about a 4 months younger.

A closeup of their little pigs. They are friendly and trusting.

One thing about pigs is that no matter how big their pen is, they prefer to hang out, cheek by jowl on the fence, occasionally gnawing on it.
When it rained, the hogs dug everything out and the whole pen flooded. To help the hogs stay dry, they put chips in the front. The ground is raised up significantly. If the hogs wanted to, they could leap that hog panel. They are content to spend their time eating, sleeping and playing.

Above you can see a hog having fun by rooting in the chips. He jams his nose in the dirt and flips up his head. They root even when they've got plenty of food, explaining why
feral hogs are so hated.

When the hogs are gone, Bill says he'll plant corn in the pig pen. The hogs have been dunging in there for months so there's a lot of nitrogen to utilize. Corn is good because it needs nitrogen and the part that humans eat is far from any bacteria on the ground.
The pigs line up at feeding time. Although they've got a feeder, the novelty and surprise factor is very compelling. Bill says they absolutely love greens and any forage, including grass. Such feed is good for the
fat quality, because of the antioxidants.
Bill's Mangalitsas love him and like to get touched by him.
There's a book whose title (in German) is "
Healing Pigs Naturally". It is about alternative medicine - for pigs. Among other things, you can massage them and feed them special plants that kill parasites (instead of drugs refined from those plants). I know Bill will grow those plants for the pigs if he can; that's very Herbfarm.
