Depends what the species and individuals are...
look in the gallery for much, much worse examples in Europe - every falconry or bird-of-prey centre maybe? - plenty of 'rescue sanctuaries' - there are so many to chose from....

If I was going to answer you which I am not, I would need some more info... how old is the Red River Hog, is it being hand-reared for some reason, how long does it stay 'on-show' here' etc - there must be more questions which dont immediately spring into my mind.
I am certainly not going to start 'naming' any zoos, as there are plenty of examples of worse enclosures in the galleries, an example being one where 12 adult tigers share one outdoor cage on a 'rotational basis, and others where animals are still shut out on display to force them to exhibit themselves...
@lintworm
Yes this is what I meant, just to be clear. It doesn't even has to be a major zoo (which is the case here), just a zoo that would have (a) red river hog in such a pitiful environment in this day and age.
I know nothing about the American style rotational system you say has been newly built at Columbus, so can only comment on the post. It is described as a 'Rotational Exhibit' not a Red River Hog exhibit - so it would be helpful if someone who knows why it was designed and how it works could explain, so that judgements could be made based on something more than a photograph. Comparison is invited for Europe where 'Rotational' exhibits are not the norm; as I said the only one I know of personally is an English zoo rotating 12 adult tigers in one cage.
The other pictures of the 'Encounter Village' show a pretty complex with a very artificial theme. It looks designed to house/exhibit what the Americans call 'Ambassador Animals', which often spend much of their lives in sub-standard accommodation hidden from both the public and from ZooChatters cameras. Again it would be useful if someone who knows could tell us.
