Depends on how it's coded.
If it HAS to be in a mystic forest biome or else it dies, then you'd have to get a mystic biome page for mystcraft (if it even exists) and build the zoo there.
If it's life is tied to being within X of where it spawns, you might be able to place the zoo at the same coordinates in another world.
It could be quite a few ways to kill it, each with the possibility of a work around, but no way to be sure.
Try going through a mystcraft crystal portal with it, and see if it'll live long enough to reach the other side.
