Daily feeding enrichment for laboratory macaques: Inexpensive options (2000)

Reinhardt, V., Garza-Schmidt, M.

Abstract

The feeding enrichment options described here are structural elements of the cage, redesigned in such a way that they serve as primary feeders for the daily biscuit ration. Therefore, no extra time is needed to clean them and to bait them with special food. ... The cages of animals fed from food or ceiling puzzles are distinguished from the others by the absence of spoiled biscuits.
