What are some of the activities the zebra uses energy for?

It may seem fairly obvious that they use the majority of their enegry eating and fleeing from larger predators, but in fact the Zebra uses it's energy for the production of smaller Zebras. Yes sex. Zebras aren't known for their sexual habbits, but in theory thay go at it more than rabbits do. So to conclude, Zebra's spend their life time behind or in front of a fellow Zebra.
