Traditional handling procedures of laboratory nonhuman primates are an intrinsic source of distress: What can be done?

With some professional expertise and goodwill, there should be no real need to resort to forceful restraint when doing research with nonhuman primates.

Enrichment options: Food pods and mesh feeders

Food pods are a recent innovation and are constructed primarily of PVC tubing whish, in turn, is fastened to nets or firehose. The object is to extract foods which have been placed in the tubes via internalized, gorilla-proof, access seals....

Documenting positive reinforcement training for chimpanzee urine collection

The mean duration of training time to the first collection and to reach reliable performance were 66 minutes and 237 minutes respectively in group-housed animals. [Training protocol is not described.]

Causes of body rocking in chimpanzees (Pan troglodytes)

The development of rocking may be prevented if the babies are left with the mother and in their social group. Rocking after (late) separation may be prevented when transfer takes place together with familiar peers.

Wounding aggression during the formation and maintenance of captive, multimale chimpanzee groups

Based on a 14-year survey of one facility, the incidence of injuries resulting from aggression during and after group formation of chimpanzees is assessed and its managerial implications discussed. There is more wounding and more severe wounding in groups composed...

Chimpanzees in AIDS research: A biomedical and bioethical perspective

The present article represents a consensus view of the appropriate utilization of chimpanzees in AIDS research arrived at as a result of a meeting of a group of scientists involved in AIDS research with chimpanzees and bioethicists. The paper considers...

Improving the laboratory environment for nonhuman primates

Environmental improvements include construction of large indoor cages that allow pairing of experimental animals, a grass-covered 'playground' for breeding chimpanzee groups, and indoor/outdoor group housing for 'retired' experimental animals. In addition, we provide toys, perches, mirrors, and foraging devices, and...

Feeding enrichment and body weight in captive chimpanzees

Regular offering of frozen foods and liquids, grains, dried fruit and foods presented in foraging devices resulted in a body weight increase of female but not of male chimpanzees.

Effects of predictable versus unpredictable feeding schedules on chimpanzee behavior

These findings indicate that feeding on a more unpredictable schedule may lead to increased species-appropriate behavior [more activity, less abnormal behavior] in group-housed chimpanzees.
