Domestic rodents, particularly those living in urban populations, represent a serious public health problem, and effective control measures are required to deal with this threat to human health. Because of the characteristic interactions between individual animals, certain behaviour patterns occur in rodent populations that are of particular concern to control biologists.

In this article, we refer to an original opinion paper written by Prof. Frank Beach in 1950 (“The Snark was a Boojum”). In his manuscript, Beach explicitly criticised the field of comparative psychology because of the disparity between the original understanding of comparativeness and its practical overly specialised implementation. The influence of escape motivation in bar-biting in laboratory mice has been most elegantly demonstrated by Nevison et al. (Nevison et al., 1999, Lewis et al., 2001), who found that mice preferentially chew at bars in sections of the cage lid that are opened periodically (thereby being those most likely to offer the opportunity to get out of Biotechniek 27, 24-5 and body weight changes) combined with Beynen AC, Baumans V, Herck H van, Stafleu FR detailed pathology provides the best means (1988c) Practical experiences with the assessment of assessing attempts to improve the of discomfort in laboratory rodents in conditions of laboratory animals. Locomotion is the main behaviour animals use to avoid aversive stimuli or gain access to resources, thus pacing stereotypies may provide a window into motivation to leave the enclosure.

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].

Throughout its history, the NWRC and its pre-decessor laboratories have worked closely with numerous partners, including other units within Wildlife Services, Abstract 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 wi 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.

Many stereotypies can be induced by confinement; for example, cats pace in zoo cages. Pregnant sows whose feed is restricted bite at their stalls' bars and chew without anything in their mouths. In laboratory rats and mice, grooming is the most common activity other than sleep, and grooming stereotypies have been used to investigate several animal models of anxiety and depression.

The value of small rodents to biomedical research is beyond question. About half of the extramural grants awarded annually by the US National Institutes of Health require some use of laboratory animals. Because more than 95% of such use involves mice and rats, public investment in rodent …

It is the consequence of an abnormal animal in an abnormal environment. These behaviors are unvarying in form and are performed almost identically on each repetition. Stereotypic behaviors are repetitive and fixed in posture and behavioral sequencing. Laboratory primates experience a plethora of stressors, potentially including injections, blood drawing, cage changes, physical and chemical restraint, and participation in scientific procedures.

Stereotypies in laboratory rodents originate in thwarted attempts to leave the cage

In caged mice, barbering (fur and whisker trimming) is another example of a stereotypy that has become a normative behavior pattern within the context of inadequate living conditions (Anonymous). It is the artificial environment in which stereotypies develop that is “abnormal” as it does not allow In laboratory rats and mice, grooming is the most common activity other than sleep, and grooming stereotypies have been used to investigate several animal models of anxiety and depression. [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 .

It is the consequence of an abnormal animal in an abnormal environment. These behaviors are unvarying in form and are performed almost identically on each repetition.

Both definitions agree that stereotypies are repetitive behaviours. 1991-12-01 · Established stereotypies are also commonly performed when little is happening in the environment, and arousal is probably low.

Present evidence from experimental studies is ambiguous. When Zur:ICR mice were selectively prevented from stereotypic wire gnawing at the cage lid, the previous amount of stereotyped behaviour after a short-term decrease in activity was compensated by variable active behaviour on the cage floor.

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). Locomotion is the main behaviour animals use to avoid aversive stimuli or gain access to resources, thus pacing stereotypies may provide a window into motivation to leave the enclosure.

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.

Evidence for a relationship between cage stereotypies and behavioural disinhibition in laboratory rodents. Behavioural Brain allowing the animals to roam areas usually off limits to them. The gorillas weren’t able to leave … 1998-10-01 Thus domestic rodents are brought into contact with indigenous species and the inevitable exchange of parasites may then produce unpredictable threats to human health. The role of both wild and domestic rodents in the transmission of certain infectious diseases, such as plague, sylvatic Venezuelan encephalitis, South American haemorrhagic fevers, murine typhus, and cutaneous leishmaniasis, is Many stereotypies are signs of frustration, with the subject being chronically thwarted from expressing basic activities such as taking a few free steps in one direction, climbing and perching, retreating to a secluded place, foraging, and interacting with another conspecific (Reinhardt).

These unsuccessful attempts of adjusting could also be described as G. J. (2002). Evidence for a relationship between cage stereotypies and behavioural disinhibition in laboratory rodents.
