The photo I uploaded of the exhibit structure didn't give a really very good view of how the yard itself looked, so I figured I'd upload this so you guys could see. This is only one side of the exhibit, but the other side looks pretty much the same. Features a few breeds, list in comments.
The exhibit features signage about where diary products come from and scheduled milking demonstrations are held there. The cattle yard wraps around the structure and it sits in between the two sides.
The yards closer to the camera (on both sides) are alpaca yards. The one farther away holds llamas. The small building is used to sell grains in ice cream cones to feed to the animals. They are only sold within a certain window of time through the day.
This is the only viewing area for the general public. Beneath it is a path that people doing special experiences can view them from. Also, this is one of two enclosures taking up the space that used to be the African elephant yard.
Features hoofstock like sika deer (Cervus nippon), fallow deer (Dama dama), American elk (Cervus canadensis), red deer (Cervus elaphus), American bison (Bison bison), llamas (Lama glama), and various breeds of domestic cattle (Bos taurus) free-roaming through the space.
