They are all present in zoos, and most of them are doing fairly well. In many ways zoos are in a good position to serve the grazing animals. For a start these animals are always likely to be at some risk in the wild because the majority of them are edible, and many of then are prized by hunters who still like to prove their prowess by gunning down a deer. Secondly, they are relatively easy for zoos to accommodate. You don't need too many purpose-built concrete edifices to house a herd of deer, just a spacious field, and some rudimentary stabling.
Zoos have a long and enviable reputation for their keeping of hoofed animals.
The record of cooperation is encouraging, and gives hope not only for future reintroduction projects with hoofed mammals, but with every other group of animals as well. Zoos that specialise in grazing mammals will usually be spacious, and will keep large and healthy herds. Look out for them.
