Effect of cage-induced stereotypies on measures of affective state and recurrent perseveration in CD-1 and C57BL/6 mice

Stereotypies are abnormal repetitive behaviour patterns that are highly prevalent in laboratory mice and are thought to reflect impaired welfare. Thus, they are associated with impaired behavioural inhibition and may also reflect negative affective states. However, in mice the relationship...

Relationship of thyroid and adrenal function to fur-chewing in the chinchilla

The fur-chewing chinchillas showed increased thyroid activity (P < 0·5), increased adrenalcortical function (P < 0·05) and decreased rectal temperature (P < 0·01). This study suggested that increased endocrine activity could be due to the loss of insulation over the...

Some observations on the development of feather pecking in poultry

Feather pecking occurs much more often when chicken are kept on wire floor rather then litter which allows the hens to peck up additional food particles. It is argued that feather pecking in the absence of a suitable litter substrate...

Abnormal behavior in laboratory-reared rhesus monkeys

Thus, even after extensive social experience, early stimulus deprivation produced animals that failed to perform normally as adults.

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"
