Abnormal/Problematic Behavior

The fibre requirements of horses and the consequences and causes of failure to meet them

Failure to meet the minimum forage requirement of 1.5% of the horse's bodyweight and the opportunity for foraging for a minimum of 8 h a day (not going without this opportunity longer than four to five consecutive hours) can have...

Green clay: Not just for a pretty face

Mice can be prone to skin lesions for various reasons. Green clay is a non-invvasive method to treat such skin lesions, and does not require veterinary approval or have properties that may interfere with an experiment. Green clay is ost...

Comparison of single- and double-spaced feeders with regard to damaging behavior in pigs

This work compared the behavior and performance of 24 groups of 12 pigs kept in pens with either a DOUBLE [one feed space aligned with the front wall of the pen (WALL), and one immediately adjacent (IN)] or SINGLE (WALL...

Evaluating depression- and anxiety-like behaviors in non-human primates

Depression and anxiety are some of the most prevalent and debilitating mental health conditions in humans. They can present on their own or as co-morbidities with other disorders. Like humans, non-human primates (NHPs) can develop depression- and anxiety-like signs. Here,...

Functional analysis and successful treatment of a captive rhesus macaque’s disruptive behavior

Functional analysis (FA) is a method developed and used by behavior analysts in human clinical settings to identify possible environmental variables that reinforce undesired behavior. FA is increasingly being applied to better understand the behavior of nonhuman animals. When training...

Nonhuman primate abnormal behavior: Etiology, assessment, and treatment

Across captive settings, nonhuman primates may develop an array of abnormal behaviors including stereotypic and self-injurious behavior. Abnormal behavior can indicate a state of poor welfare, since it is often associated with a suboptimal environment. However, this may not always...

Effect of enrichment items on the physiology and behavior of sows in the third trimester of pregnancy

Modern intensive pig breeding harms animal welfare, which is especially noticeable for pregnant sows kept in confinement stalls. This study aimed to evaluate the effects of enrichment items on the movement and physiological parameters of sows in the third trimester...

Stereotypic behaviors are associated with physiology and immunity differences in long-term confined sows

Pregnant sows in the confined environment have poor welfare and frequently perform stereotypic behaviors. In order to clarify whether highly stereotypic behavior is a sign of increased stress and successfully contributes to coping with or adaptation to adverse environment, fifty...

Characterization of a jumping stereotypy in gerbils (Meriones unguiculatus) and assessment of opaque tubing enrichment on stereotypies and breeding

Mongolian gerbils can develop stereotypic behaviors, including corner digging. At our institution, gerbils also engage in repetitive corner jumping, which we sought to characterize as a potentially novel stereotypy in gerbils. We then attempted to mitigate this behavior by mimicking...
