Disclaimer: IANAF, this info comes from pure curiosity and reading.
He was describing wild boar interbreeding as being the source of fur and tusks but AFAIK any hog allowed to mature in nature instead of captivity will develop fur and tusks. I haven't found clear explanations as to why the fur happens (weather? Food? Sessile vs active lifestyle?), but any hog allowed to go feral in the wild will look like a hairy, angry, dangerous animal. edit: The tusks differ just because of trimming and age.
Which fits with the description of the pigs being allowed to roam in captive forests.
One thing that stands out is the timeline - the article describes 3 years to mature enough to be allowed into the forest.
In modern factory farming, pigs are generally slaughtered at 6 months, and if they're being bred they start breeding at around a year. Treating pigs as immature at below 3 years is a staggering difference.
