AI Article Synopsis

  • Cynomolgus macaques are vital for biomedical research, especially in studying geriatric diseases, but socially housing sexually mature males presents challenges due to potential aggression, particularly with those previously kept alone.
  • This paper details a 2.5-year experience at IPB University, focusing on successfully housing young adult males and the difficulties encountered while trying to group older males aged over 15 years, using temperament assessments for pairing.
  • The research concluded that older males are best housed in pairs or triads determined by their temperament and dominance, highlighting the importance of behavior assessments and veterinary management in these social housing efforts.

Article Abstract

Cynomolgus macaques () serve an essential role in the advancement of biomedical research. Aged macaques, in particular, are highly valued as animal models for the study of geriatric diseases. While social housing has become the default for nonhuman primates (NHPs), socially housing sexually mature males poses a unique challenge. Moreover, socially housing aged males that have been previously kept in single housing may pose even greater challenge and risk due to a higher likelihood of aggression. Temperament assessment plays an integral part in determining the success of social housing arrangements of NHPs. In this paper, we report our work at the Primate Research Center of IPB University in integrating behavior observation and veterinary management to socially house adult, male We describe our experience in successfully housing young-adult, male ( 8-10, aged 6 years) for over 2.5 years, and the multiple efforts to socially house a small group of previously singly housed aged, male ( = 6, aged >15 years). The temperament of each was considered in the planning and implementation of social housing attempts. While a simplified behavioral observation was performed for the young adults, a more rigorous PAIR-T assessment was performed on the aged . A group formation was initially attempted, aiming to achieve a small group of six aged, male . While this group at first showed promising outcomes, significant incidents of aggression required regrouping as pairs or triads wherein the subject combinations were determined based on temperament and dominance. A total of three attempts were made to house these aged in a small group throughout the course of 17 months, and the results showed that at our facility, aged, male are best housed as triads or pairs, with selections based on their temperament and dominance compatibility. We concluded that behavioral assessments and veterinary management are pivotal in supporting the social housing efforts of adult, male in order to optimize their well-being.
