     Renewed emphasis has been placed on providing social housing for all laboratory-housed nonhuman primates. Information identifying factors affecting compatibility would aid managers in selecting animals for prospective pairings. This study investigated predictors of: 1) compatibility assessed at introduction, and 2) risk for wounding during subsequent social housing. Subjects were 674 pairs of pigtailed macaques (Macaca nemestrina) housed in protected (n=674) and full (n=87) social contact at Washington National Primate Center between 2005 and 2012. The introduction protocol involved introduction and observation over a period of days (median number of days=2). Logistic regression was used to identify factors affecting compatibility and wounding. P values ? 0.05 were considered statistically significant. Significant predictors of initial compatibility were: age, presence of aggression or wounding during introductions, number of introductory sessions, and a compatibility rating based on behavior, assigned on the last day of introduction. Age and weight differences were not significant predictors. Predictors of wounding were analyzed separately for Male/Male, Male/Female and Female/Female pairs. Significant predictors of wounding included length of pairing and age class for M/M pairs and contact aggression on the first day of introduction for M/F pairs. There were no significant predictors of wounding for F/F pairs. These data suggest that it may be more difficult to predict long-term compatibility in F/F pigtail pairs.
