The Non-Human Primate

In comparison to rodents and other smaller species, the proportion of non-human primates (NHP) used in animal-based research activities is minimal. For most NHPs, vision is the dominant sensory modality. They are highly reactive to visual stimuli and make considerable efforts to gain visual information about their surroundings. There are substantial differences when it comes to social structure and behavior between the most common laboratory NHP species. The captive environment provided to NHPs should aim at stimulating them and improving their psychological well-being, while reducing fear, anxiety, and stress responses. In their natural environment NHPs will spend most of their waking hours foraging. Thus, in captivity, providing a variety of ways for NHPs to acquire their food will promote this important behavior. While training increases the efficiency and ease of working with NHPs, it also increases cognitive stimulation and is a source of enrichment.
