Some abnormal behaviours may be related to environmental conditions (e.g. captive housing) whereas others may be due to medical conditions. The list does not include behaviours in animals that are genetically modified to express abnormal behaviour (e.g. reeler mice). A polar bear performing stereotyped pacing.
Providing visual stimulation (an open window to the outside) to a stalled horse reduces risk of stable vice occurrence. Weaving is a behaviour in horses that is classified as a stable vice, [1] in which the horse repetitively sways on its forelegs, shifting its weight back and forth by moving the head and neck side to side. It may also include ...
Rather than refer to these behaviors as abnormal, it has been suggested that they be described as "behavior indicative of an abnormal environment". [2] It was once thought that stable vices may be learned by observing other horses already performing the behaviors, but studies on the topic to date have failed to establish this as a cause. [3]
Cribbing is a form of stereotypy (equine oral stereotypic behaviour), otherwise known as wind sucking or crib-biting. Cribbing is considered to be an abnormal, compulsive behavior seen in some horses, and is often labelled a stable vice. The major factors that cause cribbing include stress, stable management, genetic and gastrointestinal ...
Lameness is an abnormal gait or stance of an animal that is the result of dysfunction of the locomotor system.In the horse, it is most commonly caused by pain, but can be due to neurologic or mechanical dysfunction.
Lignophagia is the abnormal behaviour of chewing and eating wood. [1] It has been recorded in several species, but perhaps most commonly in horses where it is usually called, simply, "wood chewing". Lignophagia is a form of the pica disorder , in which normally non-nutritive substances are chewed or eaten.
However, any horse that can store excess amounts of glycogen, usually genetic, can develop this form of ER. [1] Recurrent Exertional Rhabdomyolysis (RER) is commonly found in breeds that are high strung such as Arabians and thoroughbreds. However, any horse can develop this type of ER if it displays abnormal muscle contractions. [1]
