Animal training programs are used at many animal facilities to refine human-animal interactions. While there is a strong focus on positive reinforcement training (PRT) over negative reinforcement training (NRT) or punishment, animals vary in responsiveness...
Alopecia is relatively rare in wild primates but more frequent in captive settings. We investigate whether increasing the quantity and variety of produce enrichment reduces alopecia. Alopecia was scored bimonthly from September 2011 through mid-November...
Alopecia in captive macaques is assumed to have a behavioral cause; either by over-grooming, or a result of stress. Analysis of behavioral treatments of alopecia remains elusive, yet facilities are accountable for treatment. Retrospective analysis...
Alopecia is a persistent problem in laboratory macaques, and is important to address due to the perceived implication for health and psychological well-being. Alopecia ratings were taken at 4 time points over a 12-month period...
Environmental enrichment is provided to laboratory-housed nonhuman primates to encourage species-typical behaviors. Some enrichment is labor intensive so quantitative studies should be undertaken to assure that the benefit is worth the effort expended. This study...
Alopecia is a common problem in rhesus macaque colonies. A possible cause of this condition is hair-pulling; however the true relationship between hair-pulling and alopecia is unknown. The purpose of this study was to examine...
Recently, there has been an increase in the implementation of social housing as an effective behavioral management strategy to improve the psychological well-being of captive nonhuman primates. Social housing nonhuman primates with conspecifics provides many...
Chronic pain and distress are universally accepted conditions that may adversely affect an animal’s quality of life (QOL) and lead to the humane euthanasia of an animal. At most research institutions and zoological parks in...
Locomotor stereotypies are behaviors often seen in singly housed rhesus macaques (Macaca mulatta) and are considered to represent a maladaptive response to captive environments. Social housing is the most effective means for decreasing abnormal behaviors...
Foraging opportunities are a key component of enrichment in captive nonhuman primates (NHP) providing manipulative opportunities in which animals can engage in species-typical behaviors. Recent studies suggest captive NHP populations have increased body weight over...
