Abnormal/Problematic Behavior

Social housing ameliorates behavioral pathology in Cebus apella

No specific enrichment devices were included in the [single-] cages. The seven subjects' mean percentage of occurrence of stereotypic behaviors was 13%.Change from single- to group-housing effectively reduced stereotypic behaviors; however, it also was associated with more passive behaviors being...

Ecological aspects of chicken husbandry – Interaction between environmental condition, behavioural activity of hens and quality of deep litter

Under low light conditions behaviour activity decreases but feather pecking increases strongly. Feather pecking therefore can be interpreted as a deficiency in light stimuli for the initiation of normal behaviour patterns in a deep litter system.

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...

Differences in behaviour among adult male, female pairs of cotton-top tamarins (Saguinus oedipus) in different conditions of housing

Animals living in upper-row cages were more active and engaged in more close contact amicable behavior than animals living in lower-row cages. Those located in the half of the room nearer the window were more active than those on the...

Feather pecking and chronic fear in groups of red junglefowl: their relationships to dustbathing, rearing environment and social status*

We feel that is useful to see feather pecking as an abnormal development of the perceptual mechanism responsible for the detection of dust for dustbathing and the exposure to salient stimuli at an early stage may be crucial. .. If...

Behavioral effects of enrichment devices on laboratory primates with stereotypic and self-directed behavior

Single-caged long-tailed macaques showed a decrease in self-directed behavior, especially self-biting, floating limb, hair pulling, and excessive licking, when treats were in the feeder. Paradoxically, both pacing and rocking increased when treats were in the feeder. A temporary reduction in...
