Once people were gone, the boar took over. I think the pigs were not able to survive in the wild, but the boar thrived in the abandoned towns — because they’re so robust.

A domestic pig would survive better and live longer ( many years) in the wild than in a normal farm setting. A domestic pig raised on a farm has life span is 6 months. The domestic pig lifestyle consist of being pend up all its life (6months) in a small enclosure and fed constantly with the same high quality feed every day with no variety. The domestic Pig offspring can still grow incisors for protection and for rooting the ground to feed. This is another example of a scientist simply not known what a domestic pigs is and its farm life is like or he is not telling the truth due to his true agenda. I assume he is lying because of his true agenda.

It is more like wild pigs were bred until they could no longer survive in the wild. Bred for large size and quality of the meat vs abilities to survive in the wild.

It was easy to expect wild animals to survive better in the wild, in the same way that it would be easy to see domesticated animals having more advantages when used by humans.

Radioactivity is not such a danger in the short term for wild animals, they do not depend on having long lives or full fertility to survive in an ecosystem without specially important depredation.

and no way they could have survived in the wild

Don’t underestimate those cute domesticated piggies. They are intelligent in a certain sense and they can and will eat anything. There are even cases when they attacked and ate their feeding farmer, right in the cage, for hunger or rage of bad treatment the day before etc. It would be probably so , that left in the wild, the fittest of them will quickly abide and survive while the majority won’t, that’s where you’re right. And that surviving pigs will surely quickly develop back to boars then, two or three generations I bet. It’s the same when urban citizens left in the jungle, a few may and will do, the big rest is not detectable anymore after some hours or days.

The Pig-boar hybrids or “Inobuta” are a menace in the southern US as well, especially Texas.

The hybrids are generally bigger and bolder than pure boar, and have more fatty meat with less “gamey” taste.

I think the pigs were not able to survive in the wild

Stopped reading right there.

Conflicted over ‘some insensitivity to those displaced’; the opportunity to ‘point a finger’ at another ’Corporate Japan’-made disasters; and, the absolute bizarreness of the topic: “Radioactive swine hybrids”

Apparently, it’s trending across the world as a matter of both concern, and parody:

Now it’s “Radioactive swine hybrids”?!? - The world continues to watch Japan’s daily, unfolding circus “side-show”.
