Evaluation of social enrichment for aged rhesus macaques

The effect of a compatible companion on the behaviour and bodyweight of eight previously single-caged, 31-36 years old rhesus macaques was assessed 16 months after pair formation. The aged subjects preferred to stay in close proximity with their companion even...

Sound and its significance for captive primates

Observational research subjecting a pair of cotton top tamarins to the sound of other tamarins and ambient environmental noise yielded significant increases in autogrooming and vocalization while simultaneously yielding significant decrease in allogrooming and scanning. ... The efficacy of this...

Using the mesh ceiling as a food puzzle to encourage foraging behaviour in caged rhesus macaques (Macaca mulatta)

An attempt was made to encourage more foraging behaviour in eight pair-housed adult rhesus macaques (Macaca mulatta). No special device and no special food were used. Daily commercial dry food rations consisting of 33 bar-shaped or 16 star-shaped biscuits per...

The resocialization and rehabilitation of humanized and abused primates

Author presents case histories of Primarily Primate's treatment of individual primates with problems common to humanized and abused primates. Among the methods effectively used were gradual introduction to other primates, (sometimes with the use of portable cages), surrogate mothers, territorial...

Promoting increased foraging behaviour in caged stumptailed macaques

Simply remounting the food box [of single-housed subjects] a few centimeters away from the access hole resulted in a 69-fold increase in total time engaged in [biscuit ration] food-retrieving activities.

Nonspecific diarrhea in the alpha-male of a breeding troop: A case report

Bob's prompt recovery from intractable diarrhea upon being removed from his troop suggests that asserting his role as alpha-animal constituted a chronic social challenge that may have altered his resistance to facultative pathogens and/or autonomic neural tone, to produce diarrhea.

Modifying spider monkey behavior with the use of environmental variables

The introduction of the leaves and the food pod [food loaded PVC pipe with finger holes suspended from tree] reduced the amount of off-display time by nearly half. During baseline observations, the monkeys spent 7.3% of the time feeding, but...

Mealtime activity for lemurs

An enrichment feeding technique for lemurs that is inexpensive and requires minimal preparation time, yet seems to give the lemurs a chance to exhibit natural feeding behaviors. I used the hard outer shell of half a coconut and filled it...
