Primary forage feeder for singly-caged macaques (1994)

Murchison, M. A.

Abstract

Perforated feeder box requires the single-housed subject to use the fingers to maneuver biscuits to access holes at different levels. Apparently the animals consumed nearly all the food retrieved from the forage feeders, leaving less on the cage floor to become contaminated. The animals spent significantly more time foraging with the forage feeder than the standard feeder.
