I recalled I last saw the herd of oxen in Chester Zoo and Whipsnade Zoo a few decades ago, what about another collections?
Besides the above two, i can only think of London, Woburn and Edinburgh as having musk ox in the past.

what will they be hybrids of?Great news; even if any young born will be hybrids.
what will they be hybrids of?
I don't think that matters at all. The animals are never going to be used for anything other than display (i.e. they aren't going to end up being released into the wild anywhere).
oh yes I quite agree, zoos should preserve pure subspecies as much as possible. It is just in this case I personally don't think it matters. These musk oxen are very unlikely to be used for any kind of wild conservation programme (i.e. release) and the likelihood is that they will breed for a bit, new animals will be brought in, they'll breed some more, but they won't really become overwhelmingly productive. They will stay as a small captive population in the UK and that is all. The wild population was reduced to basically two populations which are separated as subspecies largely on the smaller size of wardi (I gather that while there are some genetic differences they are not great). Hybridising Sumatran and Siberian tigers isn't a good comparison because they are very different physically and genetically (and, I would guess, ecologically), and their very future offspring could well end up being used for reintroductions. A better comparison might be something like German red squirrels and English red squirrels?Personally I think, where possible, zoos do have a responsibility to maintain pure subspecies in captivity, but it isn't life or death if they can't. In the case of musk ox where there aren't too many individuals about, then it's more important to keep up genetic diversity.
However, if mixing subspecies doesn't matter then why do people [including me] suddenly get worried when they see a Siberian tiger mixed with a Sumatran, as likewise I doubt the animals would be used for future release and using the mentality we've applied to musk ox, it will still be a tiger. [Not arguing the point, I've probably answered my own question but I am genuinely interested in why ssp. mixing is considered ok practice in some species and absolutely forbidden in others?]

I doubt it. These squirrel subspecies look quite different in late summer.
