Just one point I'd like to make that doesn't make any difference for the match. It that a bad thing though? Providing hay, lucerne (as seems to be the case here) or browse, either in a feeder or otherwise is an essential part of ungulate husbandry, both in terms of enrichment and nutrition. Practically all zoos I know well provide this to their ungulates even if natural grazing is possible, and I highly suspect Beauval does it too. In fact, the gallery clearly shows that Beauval doesn't rely on "natural food" only, which is a good thing. The gallery does suggest that Beauval's preferred method is to just put the hay (or lucerne or...) on the ground, which has both advantages (e.g. also using it as bedding) and disadvantages (e.g. wasteful and more contamination from urine and feces).
