Abnormal/Problematic Behavior

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...

Abnormal oral behaviours in fattening bulls: incidence, causation and implications

Abnormal oral behaviours, such as tongue playing and nibbling at objects or at coat, tail and ears of penmates, are common in fattening bulls housed on fully slatted floors and fed intensively. .. Half of the groups were fed with...

Environmental enrichment in flatdeck accomodation for exploratory behaviour in early-weaned piglets

Enrichment [rubber glove, rubber dog toy, strip of plastic suspended in the pen] increased normal exploratory behaviours while reducing the incidence of disturbed manipulative behaviours [oral manipulation of pen mates] and decreasing fear responses to people.

Environmental enrichment caters for the behavioural needs of the animals, and improves their health and welfare as much as any other environmental factor. The provision of play articles or bedding may be a simple way to achieve environmental enrichment, allowing...
