An animal feed bunk has a base of arcuate cross section which in the upright feeding position supports above it a trough of arcuate cross section. The base can be detached from the trough, and inverted relative to the trough and reattached to the trough so that the bunk in the inverted position occupies much less space than in the upright position, and has its parts firmly secured to one another to prevent them from being misplaced or lost. In the inverted position, a plurality of bunks may be stacked sturdily upon one another, so that a bottom bunk in the stack has a substantial part of its base and trough fitted snugly within the trough of the bunk above it.
