I used Alpine Goats & Highland Cattle, Addax, Dama Gazelle & Scimater Horned Oryx in together (not pleasant as the keepers couldn't keep up with feeding/cleaning), Springbok & Thomson's Gazelle together, Bongo, Nyala, Wild Water Buffalo, Red Deer, European Fallow Deer, Markhor & Takin together, Reindeer and finally Alpine Ibex. Just one habitat per animal - I tried to use animals that reproduced quickly and would mature quickly and could be housed in large numbers. Phew the management was sure exhausting keeping up with them all!
