Long-term effects of a natural foraging task on aggression and stereotypies in socially housed pigtail macaques

A supplementary feeding of approximately one cup of sunflower seeds were dispersed throughout the cage in the woodchip bedding in the middle of the afternoons, 4-6 hours after the group was fed their daily ration of chow and fruit. ......

Environmental enrichment and its effects on the individual

In macaques and baboons, stereotypy is reduced or stopped by supplying "one or more perches ... and other cage furniture", especially "a woodchip substrate which includes food items ... as provisioned substrate for foraging"

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...

Reducing feather pecking in laying hens by behavioural methods

The provision of straw encouraged pecking and reduced feather pecking among hens.

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...
