Includes stereotypies, self-injurious behavior, hair pulling (alopecia), barbering, feather pecking, tail biting, etc.
Stereotypic behaviors are repetitive invariant behaviors that are common in many captive species and potentially indicate compromised welfare and suitability as research subjects. Adult laboratory mice commonly perform stereotypic bar-gnawing, route-tracing, and back-flipping, although great...
This review will examine how individual differences in temperament might affect, or be affected by, behavioral management practices for captive primates. Measuring temperament may help us predict the outcome of social introductions. It can also...
The 3 enrichment devices had different effects on individual expression of stereotypy: supertubes decreased it, shakers increased it, and puzzle balls led to a decrease followed by an increase. We present potential reasons for the...
Self-injurious behavior (SIB) occurs sporadically in 5% to 15% of captive nonhuman primates, with over-representation among males and those animals housed in single caging prior to adulthood. Though SIB may manifest as a range of...
Abnormal behavior in macaque monkeys has been associated with risk factors such as nursery rearing and single housing. However, less is known about the extent of, and risk factors for, abnormal behavior in baboons. The...
Stress has been associated with adverse hematologic and physiologic consequences, including immunosuppression and an increased risk of cardiac disease. Aberrant platelet activation has been documented in humans exposed to mental stress, and activated platelets, as...
This study aimed to identify differences in stress measures in pigs (Sus scrofa) with different roles during a tail-biting outbreak. Quartets (n = 16) of age- and gender-matched fattening pigs including a tail biter (TB...
The effect of the provision of simple objects to stabled horses on their behaviour was investigated to determine whether these objects can affect horses' behaviour in a positive way and thus enrich their environment. A...
Some laboratory mice gnaw food pellets without ingesting much of the gnawed material, resulting in the production of waste material. The fact that this food grinding behavior is not seen in all individuals of a...
Some laboratory mice gnaw food pellets without ingesting much of the gnawed material, resulting in the production of waste material called orts. The fact that this food grinding behavior is not seen in all individuals...
