Pairing compatible female rhesus monkeys for the purpose of cage enrichment has no negative impact on body weight

Our finding supports the conclusion that keeping singly housed adult female rhesus monkeys in compatible pairs for the purpose of cage enrichment does not affect the animals' general health status as reflected in body weight.

Preliminary comments on pairing unfamiliar adult male rhesus monkeys for the purpose of environmental enrichment

A total of 7 different male-male combinations had to be tested during the period of non-contact familiarization in order to obtain 5 dyads (10 males) in which the partners exhibited clear dominance-subordination relationships (Table I). Pairing the respective males with...

Combining scientific experimentation with conventional housing: A pilot study with rhesus monkeys

The testing apparatus ... was connected to a computer that controlled the test and the distribution of regular monkey chow as reward. Manipulatory activity required by the apparatus reduced motor stereotypies but not self-biting in single-housed subjects.

Use of an artificial gum-tree feeder for marmosets

Having the opportunity to demonstrate their natural gum-foraging behavior stimulated some of the animal's other natural behaviors, i.e., compatible sharing of feeders and feeding sites, methods of food acquisition, and territoriality and dominance. .... The gum-filled syringe was used for...

Use of novel objects to enhance environments of captive chimpanzees

Following their familiarization with the novel objects [rubber or plastic toys for small children], the [group-housed] chimpanzees' manipulation frequency decreased whereas self-grooming and abnormal behaviors were increased. The importance of a periodical substitution of the objects was suggested to enhance...

Developing effective social and environmental enrichment strategies for macaques in captive groups

Perhaps this data will be useful in supporting the notion that primate cage size should not be strictly a function of the animal's size, but rather of the age and expected activity level of the monkey placed inside.

The use of naturally occurring manipulanda can reduce the frequency of cage stereotypy in solitary-housed primates

The single-housed animals demonstrated a marked reduction of cage stereotypy during the time they had the corn to manipulate.

Psychological well-being of primates in captivity

Recent amendments to the Animal Welfare Act will, upon taking effect, require that researchers who maintain nonhuman primates in captivity house their animals in such a way as to "promote their psychological well-being." Unfortunately, no consensus presently exists in terms...
