Stereotypies come in many different forms, some vocal and some motor. These behaviors vary in frequency and intensity and occur at various times throughout the day. They are often unpredictable. Stereotypies fall into two categories: Vocal; Motor; Vocal stereotypies may sound like babbling, humming, or a sing song sound.
This unit presents a quantitative, observational method for the assessment of rodent stereotyped behavior which consists of motor responses that are repetitive, invariant, and seemingly without purpose or goal. The most classic behavioral pattern that is characteristic of stereotypy is that elicited …

Statistics. In the UK in 2015, there were 3.33 million procedures on rodents (80% of total procedures that year). The most common species used were mice (3.03 million procedures, or 73% of total) and rats (268,522, or 6.5%). Other rodents species included guinea pigs (21,831 / 0.7%), hamsters (1,500 / 0.04%) and gerbils (278 / 0.01%).

Baumans (NVP) Convenor; P. F. Brain (LASA) Secretary; H While a number of studies have examined the stress associated with transport, these have typically involved laboratory rodents and livestock, and little is known of its effect on nonhuman primates. This paper reports the results of a study of behavioral changes in a group of long-tailed macaques transported by air from standard breeding conditions and then re-housed in standard laboratory 1 Modeling Wild Animal Behavior in the Laboratory: Scientific Concerns – Kimberley Jayne – Behavioral research on non-human animals (hereinafter referred to as animals) can involve the study of their evolution and natural behavior, cognitive abilities and psychological constructs, or welfare and response to stressors, among other areas of natural animal behavior.
Laboratory rodents housed in standard, empty cages exhibit stereotypic behaviors that could indicate brain abnormalities, reported Joseph Garner of the University of California, Davis, at the International Society for Applied Ethology Congress. The stereotypies – pacing, incessant grooming, repetitive cage biting and scratching – are
Although stereotypies are often automatically reinforced, it’s important to consider that, for your client, the behavior may serve a different function. Many children with autism use stereotypies for self-soothing and regulation. They should not be targeted for reduction unless they interfere with other activities. These unsuccessful attempts of adjusting could also be described as G. J. (2002).
The effects of stereotypies on the animal’s body and on the pen can also be assessed. Examples of studies where rearing condition changes have reduced the incidence of stereotypies are quoted. Whatever the function of stereotypies, if they occupy much time, say 10% of waking life, the conditions could be said to be bad for the welfare of the animal.
[13] Examples of stereotypical behaviours include pacing, rocking, swimming in circles, excessive sleeping, self-mutilation (including feather picking and excessive grooming), and mouthing cage bars. Experimental evidence seems to indicate that environmental factors such as cage size, housing type, stress and boredom which are often cited as the "causes" of stereotype in laboratory animals, do not necessarily cause the behaviour. Not all monkeys that experience these environmental conditions develop stereotypic behaviour . All mice were twice as likely to initiate syntactic chains in the laboratory than at home (F(1, 82) = 85.73, p < 0.001), and mutant mice in particular initiated approximately 25% more chains than wild-type mice in the laboratory environment (F (1,86) = 17.315, p < 0.001; Figure 4), compared to only 5% more in the home environment.

Trauma as “boundary object” Footnote 7 At the time of the Washington conference, experimental neuroses had been studied in animal laboratories in the United States and Canada for roughly a decade and neuroses had reportedly been produced in rats, chicks, goats, dogs, rabbits, monkeys, chimpanzees, doves, cats, and human children and adults (Cook Reference Cook 1939a; NRC 1937). Bar biting and other abnor- mal behaviors have been described in mice used in laboratory research as a response to premature weaning, thwarted attempts to suckle, or unpleas- ant cage experiences (Callard, Bursten, & Price, 1999; Waiblinger & Konig, 2004; Würbel & Stauffacher, 1997).
they are mutually exclusive diagnoses in humans), and the neuopsychological and neurobiological findings in animals support the conclusion that animal stereotypies are not a model of human OCD.

In a 2000 lawsuit settlement with animal-rights and anti-animal research groups, USDA had agreed to consider including laboratory rodents and birds under its regulations. However, Sen. Jesse Helms (R-N.C.) took steps to negate the settlement in February by inserting a brief clause into the Senate's version of the Farm Bill specifying the animals were exempt from the AWA.
It is most often needed in phenotyping genetically modified new rodent (usually mouse) lines or in preclinical testing of cognitive effects of new CNS drugs.

Among male rodents, elimination of the VNO seems to have different consequences (Hernandez-Gonzalez, et al., 2008). In male rats, removal of the VNO caused a reduction in the mounts ending in intromission, suggesting deficiencies in erection and activity in the striated penile muscles.
Because of the characteristic interactions between individual animals, certain behaviour patterns occur in rodent populations that are of particular concern to control biologists. Analysis of Behavior in Laboratory Rodents allowed to obtain a piece of food on a tray by reaching through a slot in its cage. To force the rat to use its non-preferred limb, a light bracelet was placed on the normal limb, thus preventing it from going between the bars. Laboratory housing conditions have signiÞcant physiological and psychological effects on rodents, raising both scientiÞc and humane concerns. Published studies of rats, mice and other rodents were reviewed to document behavioural and psychological problems attributable to predominant laboratory housing conditions. Studies indicate that rats and 2020-04-29 Indeed, stereotypies (abnormal behaviour) in captive wild animals may arise from repeatedly thwarted (i.e., unsuccessful) attempts to escape confinement (Dantzer, 1986;Mason, 1991; Clubb and They are prevalent in many captive species, including laboratory rodents [1][2][3].
