Socialization of adult male cynomolgus macaques: benefits vs

At Charles River Laboratories (Reno, NV), we have a high rate of success when socializing juvenile and sub-adult cynomolgus macaques (Macaca fascicularis). Until recently, we would rarely attempt to introduce adult males through progressive contact panels due to previous unsuccessful...

Is full physical contact necessary for buffering effects of pair housing on social stress in rats?

Our previous study showed that pair housing with a familiar male prevented an increase in anxiety caused by social defeat in male rats. The present study attempted to identify the aspects of social interactions with a familiar male that are...

Common Marmoset Care [Online resource]

The three main divisions of 'marmosetcare.com' aim respectively to promote: an understanding of the range of behaviour in this species, placing this behaviour in the context of its natural habitat and promoting good welfare in captive environments. Topics covered in...

Social isolation affects partner-directed social behavior and cortisol during pair formation in marmosets, Callithrix geoffroyi

Pair-bonded relationships form during periods of close spatial proximity and high sociosexual contact. Like other monogamous species, marmosets form new social pairs after emigration or ejection from their natal group resulting in periods of social isolation. Thus, pair formation often...

Pair housing of macaques in research facilities: A science-based review of benefits and risks

Despite the enactment in the early 1990s of regulations requiring social housing of nonhuman primates (NHP), single housing is still prevalent in American research facilities. The publication of the 2011 edition of The Guide for the Care and Use of...

Heart rates of male and female Sprague-Dawley and spontaneously hypertensive rats housed singly or in groups

This study was conducted to confirm our previous reports that group housing lowered basal heart rate and various evoked heart-rate responses in Sprague-Dawley male and female rats and to extend these observations to spontaneously hypertensive rats. Heart rate data were...

Implementation of pair housing for laboratory primates

There is a general consensus among those studying the welfare of captive primates that social housing is the most effective means for promoting psychological well-being. It is well established that socially-housed rhesus macaques (Macaca mulatta) demonstrate welfare that is superior...

Benefits of pair housing are consistent across a diverse population of rhesus macaques

Introducing singly housed rhesus macaques (Macaca mulatta) into isosexual pairs is widely considered to improve welfare. The population of laboratory rhesus macaques is heterogeneous on a variety of factors and there is little literature available to directly evaluate the influence...

Epigenetic influence of stress and social environment

Animal models of early-life stress and variation in social experience across the lifespan have contributed significantly to our understanding of the environmental regulation of the developing brain. Plasticity in neurobiological pathways regulating stress responsivity, cognition, and reproductive behavior is apparent...
