Giraffes spend up to 75 percent of their waking hours foraging in the wild, and providing feeding enrichment that matches this behavioral investment is fundamental to psychological welfare in zoo environments.
Feeding enrichment for giraffes presents an excellent opportunity for significant welfare improvement because foraging is so central to their natural behavioral repertoire. When giraffes are given access to food primarily at ground level from simple hayracks, they are denied not only the elevated browsing posture their necks evolved for but the cognitive engagement of selecting from varied browse and working to access food from challenging positions. High-level browse feeders that require the giraffe to extend fully, varied plant species that provide different flavors and textures, and puzzle-style feeders that slow intake and require manipulation all contribute to a more behaviorally rich feeding experience. Combining multiple feeding stations at different heights and locations within the enclosure encourages movement and mimics the foraging travel patterns that structure a wild giraffe's day.
