Old, socially housed rhesus monkeys manipulate objects

More than 10% of the [group-housed] females' time was spent in object [toy] manipulation. ... Socially housed rhesus monkeys ranging in age from 14 to 22 years showed steady rates of object manipulation, and their interest in familiar objects did...

Potential animal hazard with ring toys

Recently one animal, a 2-year-old pigtail macaque (Macaca nemestrina), approximate weight 3.1 kg, became trappedinside a Nylaring. The ring went around the neck, across the body, and under one arm. Since the animal was apparentlyunable to remove the ring, he...

Initial response to introduction of a PVC perch by singly caged Macaca fascicularis

Longtailed macaques ... exhibit a vertical flight response when alarmed. Therefore, the height of the cage is important for allowing the animals to withdraw from potentially stressful or alarming situations. ..Single-housed monkeys spent significantly more time clinging to the cage...

Weight gain among juvenile rhesus macaques: A comparison of enriched and control groups

Subject monkeys gained weight at the highest rate during group-housing, suggesting that the combination of food availability, exercise opportunities, and chronologic age during this portion of the study were conducive for rapid weight gain.

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...

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...

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.

Enticing nonhuman primates to forage for their standard biscuit ration

Ordinary feeder-boxes were converted into food puzzles by remounting them onto the mesh of the front of the cages, away from original access holes. The total amount of time [pair-housed] adult male rhesus macaques engaged in gathering the standard biscuit...
