The reduction of abnormal behaviors in individually housed rhesus monkeys (Macaca mulatta) with a foraging/grooming board

All of the single-housed animals foraged from the board to the point that a significant reduction in the level of abnormal behavior [5%] was noted. Most animals also groomed the fleece covering the board. Subjects spent on average 12 minutes...

Is social housing of primates always the optimal choice? In: Through the Looking Glass

Especially when new pairs are formed and dominance relationships are being established, there is a strong likelihood that the veterinarian will be kept quite busy suturing wounds. ... In a recent longitudinal assessment of six pairs of male rhesus monkeys,...

Effects of woodchips and buried food on behavior patterns and psychological well-being of captive rhesus monkeys

The addition of woodchips increased exploration and feeding levels and decreased social interactions among group-housed animals. Burial of regular monkey chow in woodchips had little effect on behavior beyond that of the woodchips alone, increasing exploration and decreasing passivity. The...

Social pairing of longtailed macaques with preferred, nonpreferred, and randomly assigned cagemates

Pair formation technique is described. All 15 [female-female] pairs were sufficiently compatible that none had to be separated.

Use of a grooming and foraging substrate to reduce cage stereotypies in macaques

We examined the effects of a synthetic fleece pad on cage stereotypies in individually housed cynomolgus monkeys. Animals exhibited idiosyncratic repertoires of stereotyped behaviour, including repetitive pacing, swaying circling, bouncing, cage charging, and rocking that occupied on average 11% of...

Comparing the effectiveness of PVC swings versus PVC perches as environmental enrichment objects for caged female rhesus macaques

Single-housed subjects' preference for perches was probably related to the fact that perches, unlike swings, are fixed structures permitting continuous relaxed postures rather than short-term balancing. Moreover, perches, unlike swings, permit the animals to sit right in front of the...

A unique housing system for rhesus macaques

From each bank of four dog cages, we removed the ceilings of the lower two cages, making a single housing unit for macaques. To each cage we added three resting perches, a climbing ladder, windows on both sides, and a...

Formation of a new social group of unfamiliar female rhesus monkeys affects the immune and pituitary adrenocortical systems

Eight adult females were introduced into an enclosure. Initial dominance rank was established within 48 h by noncontact threats and chases and was unchanged throughout the [9-week] study. Only two minor wounds were recorded. The animals showed stress responses during...
