The Effects of Predictability in Daily Husbandry Routines on Captive Rhesus Macaques (Macaca mulatta)

This study was conducted on 39 single-housed subjects in four indoor rooms at the Oregon National Primate Research Center. Temporal and signaled predictability were added to four daily husbandry events:morning and afternoon feeding, enrichment distribution, and room cleaning. Temporally predictable husbandry events occurred reliably at the same time daily, while signaled predictable husbandry events were preceded by a distinct event-specific signal in the form of a doorbell.

Care, Use, and Welfare of Marmosets as Animal Models for Gene Editing-Based Biomedical Research: Proceedings of a Workshop.

Approaches to the care and management of captive marmosets for research vary widely between institutions. In advance of the workshop, Anna Goodroe, Monica Burns, Casey Fitz, Jessica Izzi, and Keith Mansfield surveyed a broad range of marmoset facilities around the globe for their insights on key veterinary and clinical care practices in successful colonies. The data showed a number of similarities but also some differences. Presenters detailed their facilities’ practices and lessons learned related to routine animal care, diet, environment, reproduction, disease, and pain management. This chapter summarizes the main issues addressed; full details and references can be accessed in the presentation slides on the workshop website.¹

Social buffering in Adult Male Rhesus Macaques (Macaca mulatta ): Effects of Stressful Events in Single vs. Pair Housing

The purpose of this study was to test whether long‐term pair housing of male rhesus macaques ameliorated negative responses to stressful events that can occur in the course of routine husbandry or research procedures.
