A livestock container has a plurality of levels and compartments formed by a plurality of convertible platforms and compartment gates. In some embodiments, the convertible platforms are bi-fold platforms hingedly mounted to sidewalls of the container and moveable between deployed and stored positions. When in the stored positions, the convertible platforms extend minimally from the sidewall, eliminating or reducing obstacles to movement of livestock or humans. The convertible platforms are configured to rest on upper edges of corresponding compartment gates below, and the container may be free of any central post, thereby eliminating obstacles caused thereby to movement of livestock or humans. The sidewalls and floor may be formed of hollow-core extruded aluminum panels, and longitudinal channels formed therein may house pipes or electrical wires for conducting water or electricity to ventilation fans, lights, or misters, or for storing water.
