The pole-and-collar method is one of several techniques that enable the safe transfer of a nonhuman primate from its home environment into a restraint chair without the need for sedation. It has been used within...
Locomotor stereotypies are behaviors often seen in singly housed rhesus macaques (Macaca mulatta) and are considered to represent a maladaptive response to captive environments. Active and passive enrichment items are commonly used to mitigate these...
Social species of nonhuman primates, such as macaques, should be given the opportunity for social access to conspecifics. In captive laboratory settings, creating a system to provide this opportunity can be challenging, especially concerning sexually...
Hair loss is a common problem in captive macaque colonies. A potential factor is the possible influence of stressful environments in the development of hair loss. We examined the relationship between hair loss and chronic...
In practice, consideration is given to providing most of the species used in research,testing and education withsome level of environmental enrichment. However, although the current level of awareness and understanding about the benefits of environmental...
Refinement of social housing practices is paramount to improving animal welfare in laboratory environments, especially with regard to non-human primates. Even though social housing of the same species should be considered the optimal paradigm, cynomolgus...
Data collection can help facilitate the progress of social housing programs within individual institutions and in the industry as a whole. One benefit is that it provides the ability to address preconceived ideas (“myths”) with...
This device takes only a few minutes to make. 1. Start with a short piece of PVC pipe. 2. Drill a hole through both sides of the top and bottom. 3. Insert a stainless bolt...
Housing laboratory primates in large pens can improve welfare by providing ample opportunity to express normal social and locomotor behaviors. This type of housing, however, can present great challenges in terms of manipulating animals for...
Princeton University continually makes efforts to improve and enhance the quality of life of our NHPs used in research. A part of this effort is to continue to improve our environmental enrichment program, promoting the...
