A rational approach to enriched nutrition for nonhuman primates

Obesity is a concern with nonhuman primates (NHPs) housed in captivity for extended periods of time, mostly due to overfeeding and lack of exercise. This is often compounded by environmental enrichment programs that include different types of food. That is...

Space use as an indicator of enclosure appropriateness: A novel measure of captive animal welfare

Empirical measures of animal behavior and space use within the captive environment can provide critical information about animals' requirements, preferences and internal states. Chimpanzees showed significant differences in how they used structural elements (P = 0.021), mesh barriers (P =...

Effects of positive reinforcement training techniques on the psychological welfare of zoo-housed chimpanzees (Pan troglodytes)

Captive environments encompass various factors that can elevate stress levels and jeopardize the wellbeing of the captive animals. The use of positive reinforcement training (PRT) techniques enables researchers and caretakers to reduce tension directly associated with potentially stressful procedures and...

Welfare and housing of chimpanzees in captive settings

Advances in facility design, healthcare, and other strategies have produced an excellent quality of life for chimpanzees (Pan troglodytes) in biomedical research. Historically, many facilities housed chimpanzees individually or in small groups (2–3 animals). Laboratory chimpanzees today have interactive environments...

Multidimensional cost-benefit analysis to guide evidence-based environmental enrichment: Providing bedding and foraging substrate to pen-housed monkeys

Refinement of animal care and housing is an important shared goal - and challenge - of the team of research, veterinary, and animal care personnel charged with ensuring the wellbeing of laboratory animals. This study addresses 2 issues central to...

Designing environments for aged primates

In order to prevent physical and psychological deterioration in older animals, it is important to apply the same principles of environmental enrichment and housing as are applied to younger animals. As we have discussed above, the needs of aged individuals...

Videotaped demonstrator improves efficiency of training chimpanzees to urinate on cue

Studies have shown chimpanzees can learn to perform tasks by watching live or videotaped demonstrators. The present study assessed whether female chimpanzees exposed to a videotaped demonstrator would learn a husbandry-related task, urinating into a receptacle on cue, faster than...

To squeeze or not to squeeze? A Discussion on LAREF, September, 2009

The discussion was started by the following questions: "Is the squeeze-back mechanism more or less stressful than the pole and collar system for removing a macaque from his cage for an IM (intramuscular) injection?" and "How are stress levels being...

Preventing boredom in NHPs using fleece fabric and food treats
