Onychorhynchus coronatus

A combination of factors; firstly, they were never meant to remain at Zurich, with 3,3 individuals planned to come there for quarantine and move onto Jersey, but bureauocracy and other such issues meant only 1,1 arrived and they had to stay at Zurich.
Secondly, the pair bred only once and produced a litter of 4,1 piglets - but both the younger and older female died not long afterwards, leaving several males with no prospect of further imports. Had the females lived, I suspect the species may have stood a chance of hanging around as pigs are both notoriously fecund and seem relatively resistant to inbreeding depression.
I see, that is quite sad really, as had it worked out and the bureauocratic hurdles overcome I'm sure it would have meant this species becoming a long term ex-situ resident of the Jersey zoo.
Yes, I also suspect that the species would probably have eventually settled in to breeding well in captivity and could well have become somewhat established in zoos in Europe.
However, I do think that there are some suid species that have experienced inbreeding depression ex-situ. The one that comes to mind that I read about a while back was one of the barbirusa species.
