Reduction of regurgitation and reingestion (R&R) in lowland gorillas at the Oklahoma City Zoo (1992)

Wiard, J.

Abstract

The addition of browse or hay to the diet of captive gorilla reduces the occurrence of R&R [regurgitation-reingestion]. Novelty items tend to reduce R&R for short periods of time. Manipulation of how and when food items are presented reduces R&R.
