I think that Brookfield Zoo has one of the smallest collections of hoofstock for a major zoo.
Hoofstock Yards:
Bactrian Camels
Prezwalksi's Wild Horse
Addax
Grevy’s Zebras
Grant’s Zebras
Habitat Africa! The Forest
Okapi
Yellow-Backed Duiker
Blue Duiker
Habitat Afrca! The Savannah
Reticulated Giraffe
Klipspringer
Waterbuck
Warthog
Great Bear Wilderness
American Bison
Pachyderm House Might not count these:
Black Rhino
River Hippos
Pygmy Hippos (also in Tropic World)
Lowland Tapir (also in Tropic World)
Children's Zoo
Alpaca
Llama
Reindeer
Domestic Horses, pigs, cows, goats, and sheep.
