Horses with one stereotypic behavior are likely to exhibit another. Stable vices or, more correctly, stereotypical behaviours or ‘repetitive abnormal behaviours’, are a source of worry for many horse owners because it devalues the animal and can cause physical harm and unsightly muscle development over time. Stereotypic Behaviors Stall walking or circling is a stereotypical behavior in which horses walk in circles around the stall. The underlying cause of stereotypic behavior in horses remains unclear. Reducing Stereotypic Behaviors in Horses. 2) Wind sucking - similar to crib-biting but the horse sucks in air without grasping onto a surface. Stereotypic behaviours are extremely common in domestic horses, and this is most likely due to our modern systems of equine management being poorly suited to their natural behaviour. But according to Williams, the brains of horses with stereotypies may actually be different from those of their “normal” peers. Remember, stereotypies are a coping mechanism so successful treatment involves addressing all the causal factors. The best method to help prevent stereotypic behaviour is to allow your horse to engage in natural behaviours, provide sufficient paddock turnout and feed plenty of roughage! McBride, S.D. This stress may trigger the development of stereotypic behaviour which enables the horse to cope (coping mechanism) in an environment that doesn’t meet their needs. This is known as a suboptimal environment 9. Stereotypic behaviours are repetitive 10 and are consistently the same each time. Most of these are journal articles related to research that has been done on treatment methods for cribbing, wind sucking, and weaving in horses. Animal Welfare 10, 173–189. Some simple management practices might prevent horses from developing stereotypic behaviors, or reduce their frequency once established. 3) Box walking - the horse continuously paces or … 95% of these horses were being fed concentrates and/or supplements as well as pasture. McGreevy and Nicol, 1998b; McGreevy et al., 2001a), while in other species, even the average animal may spend Stereotypic Oral Behaviour in Captive Ungulates Cribbing is a compulsive behavior or stereotype that is bothersome to many horse owners because of the damage it may cause to both the horse and the farm itself. Many stabled horses perform a variety of repetitive behaviors such as weaving, stall walking, cribbing, headshaking and pawing. Several behaviors have been observed in stabled horses that match the definition of stereotypic behavior. Introduction. Common stereotypies include crib-biting, weaving, and stall-walking. Behaviors such as cribbing, weaving, and stall-walking might appear as nuisances, but … These behaviors have been called many different names including stereo- The most common stereotypies in horses are: 1) Crib-biting - the horse grasps on a hard surface, arches his neck, pulls back and sucks in air.

Cribbing: Occurs when a horse places its upper incisors on a solid object, pulls backward, contracts its neck muscles, and sucks air into the upper esophagus creating a grunting sound. An alternative explanation for stereotypic behaviour in horses relates to stress-induced alterations in central nervous system (brain) dopamine physiology.

Often referred to as "vices" because of the detrimental effects of these behaviors, they are most commonly divided into three types: oral, locomotor, and other. Types of Stereotypies. Both experimental and epidemiological studies have Dopamine is a neurotransmitter; a type of chemical released during stereotypic behaviour that helps control the pleasure and reward centres in the brain. Because stereotypies manifest physically, we tend to think of their effects in those terms. Management factors related to the time spent in the stable showed the strongest associations with stereotypic behaviour. It is defined as Factors associated with the prevalence of stereotypic behaviour amongst Thoroughbred horses passing through auctioneer sales. As a result horses are often unable to express their normal behavioural repertoire which causes an increase in their stress levels and makes the development of a stereotypic behaviour more likely. Tying the horse to prevent walking will only transform the behavior into weaving (see below). exhibit stereotypies. Sharon Smith MSc SEBC(Reg) IEng BHSAPC discusses the causes of stereotypical behaviour in horses and the best way to manage them.. Management factors related to the time spent in the stable showed the strongest associations with stereotypic behaviour. fence board or stall) arching their neck and pulling backwards against the object while gulping in … Sometimes weaving can be temporary and is brought on by sudden changes in a horse’s routine.

Owners and managers should observe weanlings closely, as researchers have reported that many horses begin cribbing at this stage. This is a stereotypic behavior observed usually among captive horses, where the horse bites its crib or a solid object, then contracts its neck in order to pull back the crib/object. Several studies have been conducted to establish links between the underlying causes and potential function of such behaviors. In Thoroughbreds, these behaviors are commonly seen in mares and 2-yr-old foals. Crib-biting in horses (Equus caballus) is a stereotypic oral behaviour.A crib-biting horse grasps a fixed object with its incisor teeth and contracts the lower neck muscles to retract the larynx caudally (McGreevy et al., Reference McGreevy, Richardson, Nicol and Lane 1995).This movement coincides with an in-rush of air through the crico-pharynx into the oesophagus, producing … Cribbing (Aerophagia, Windsucking): When cribbing, the horse usually grasps an object in the stall (such as the water bucket) with its incisors, flexes its neck, and sucks air into the pharynx. Cribbing is an example of a stereotypic behavior (formerly referred to as a vice), also known as crib-biting.
