Abnormal/Problematic Behavior
Behavioural syndromes in stereotypic striped mice
Stereotypical behaviours (SBs) are abnormal, repetitive behaviours often observed in captivity. SBs are linked to impoverished captive conditions, and stereotypic individuals show a particular set of behaviours (e.g. bolder personality, greater activity) indicating proactive coping. Yet, we do not know...

In fully slatted systems, tail biting is difficult to manage when pigs' tails are not docked because loose enrichment material can obstruct slurry systems. This pilot study sought to determine: a) whether intact-tailed pigs can be reared with a manageable...

Feather pecking is a continuous welfare challenge in the housing of egg-laying hens. Canada is currently making the transition from conventional cages to alternative housing systems. However, feather damage (FD) among laying hens due to feather pecking remains a welfare...

Read MoreDo social factors related to allostatic load affect stereotypy susceptibility? Management implications for captive social animals
Stereotypies are frequently associated with sub-optimal captive environments and are used as welfare indicators. However, susceptibility to stereotypy can vary across individuals of the same group. As such, identifying which individuals are more susceptible to this behaviour may be helpful...

Read MoreDoes cribbing behavior in horses vary with dietary taste or direct gastric stimuli?
Concentrated feed diets have been shown to drastically increase the rate of the cribbing, an oral stereotypy in horses, but the specific component causing the rise has not been identified. Furthermore, the mechanism through which feed affects cribbing has not...

Read MorePersonality predicts the responses to environmental enrichment at the group but not within-groups in stereotypic African striped mice, Rhabdomys dilectus
Environmental enrichment is used to enhance the well-being of captive animals and to prevent or reduce stereotypic and other abnormal behaviours. However, environmental enrichment does not always succeed in its intended purpose. We investigated whether personality (i.e. consistent individual variation...

Abnormal repetitive behaviours (ARBs) are associated with past, or present, welfare problems and are common elements of the behavioural repertoire of some captive animals, including birds. Millions of birds from hundreds of species are held in various captive settings, yet...

Self-injurious behavior (SIB) is a pathology observed in both humans and animals. In humans, SIB has been linked to various mental health conditions that are also associated with significant sleep disruption. In rhesus macaques, SIB consists of self-directed biting which...

Abnormal behavior occurs in a number of captive nonhuman primate species and is often used as an indicator of welfare. However, reported levels of abnormal behavior often vary across species, making general welfare judgments difficult. The purpose of this study...

Read MoreDecreased environmental complexity during development impairs habituation of reinforcer effectiveness of sensory stimuli
Previous research has shown that rats reared in simple/impoverished environments demonstrate greater repetitive responding for sensory reinforcers (e.g., light onset). Moreover, the brains of these rats are abnormally developed, compared to brains of rats reared in more complex/enriched environments. Repetitive...
