Also this list is something everyone should keep in mind when domestication becomes a thing, Predators. If what you are raising can be wiped out by a predator while you sleep you are going to either wipe that predator off the map, if you can't do that you either leave or raise something else. Now this list is what is current found in parts of Asia.
Predation[edit]
An Asiatic lion attacking an onager (Roman, c. AD 150)
The onager is preyed upon by apex predators such as
Asiatic leopards and
striped hyenas. A few cases of onager deaths due to predation by leopards was recorded in Iran, as a
Persian leopard attacked and eaten a Persian onager. Though it is said that leopards do not usually feed on equids such as in
Africa, it may be due that Asian leopards are larger and stronger enough to prey on Asiatic wild asses.
[8][9]
In the Middle East to the Indian Subcontinent,
Asiatic lions and
tigers were the biggest predators to onagers, just as
African lions are to zebras. They were also formerly by
Asiatic wild dogs,
Asiatic cheetahs and possibly
bears in their former neighboring ranges, though they may have mostly preyed on onager
foals. In South Asia,
mugger crocodiles can be great threats to onagers during migratory river crossings.
Currently, the biggest predator for onagers are
gray wolves. Investigations revealed that a 23% of prey proportion of gray wolves were attributed to the Asian wild ass. However, like most equids, they are known to have anti-predator protection. Groups of stallions cooperate and try to chase off predators. If threatened, onagers defend themselves and violently kick at the incoming predator.

Now add bears and lions in many places as well as crocodiles.
