# Corral 9 renovation to support SPF NHP breeding

> **NIH NIH P51** · OREGON HEALTH & SCIENCE UNIVERSITY · 2021 · $999,999

## Abstract

Project summary
Social housing is known to promote welfare for nonhuman primates (NHPs). Rhesus macaques living in large
outdoor corrals experience fewer episodes of diarrhea and lower wounding rates, and have less alopecia
compared to those living in other housing types. Further, macaques born in corrals show less stereotypy when
housed inside compared to those born in other housing. However, the corrals currently in use at the ONPRC
have limitations, including being located relatively far from processing areas (which requires animals to be
moved to those areas on trucks), solid walls that prevent animals from viewing their environment, and lack of
areas for introducing or re-integrating animals into the group. This supplement will allow us to renovate the
design to erect a new, innovative, half acre corral, which will allow us to increase our breeding population by
approximately 50-60 infants per year. The plan described in this application expands existing housing with a
half-acre corral tied to existing infrastructure (thus reducing the need to transport animals by truck); will provide
animals with varied enrichment options (including the ability to visualize their environment through observation
windows); and will contain an introduction area to facilitate animal reintegration. Together, the corral redesign
proposed in this supplement will increase breeding capacity in support of research, thus enhancing the
scientific endeavor while promoting animal welfare.
