“…valencia era de entre 0,31% y 1% (Muñoz et al, 2009;Tadich et al, 2012). Sin embargo, esta baja prevalencia llama la atención, ya que en caballos FSC la prevalencia de balanceo varía entre 2,15 y 2,94% (Tadich et al, 2013;Muñoz et al, 2014) y en caballos árabes es mayor a 15% (Benhajali et al, 2010;Fureix et al, 2013). Por lo que se puede inferir que podría haber factores hereditarios y/o de manejo que hacen que esta estereotipia sea de tan baja presentación en el caballo chileno.…”

RESUMENEn Chile se han realizado dos estudios de estereotipias clásicas en caballos de raza chileno, ambos con resultados diferentes respecto a la prevalencia total y estereotipia más frecuente en esta raza. El objetivo de este estudio fue determinar la prevalencia total y de cada una de las estereotipias clásicas en caballos chilenos estabulados de las comunas de Pinto y Coihueco, Región del Biobío, Chile, y su asociación con el sexo y edad. Se estudió la totalidad de los caballos chilenos inscritos y estabulados en ambas comunas (n = 103). Se determinó la presencia o ausencia de aerofagia, balanceo y/o paseo circular en pesebrera en cada caballo mediante observación directa, 20 min por hora, durante 4 horas. Para analizar los datos, los equinos fueron divididos de acuerdo al sexo en 3 grupos: machos enteros (n = 36), machos castrados (n = 33) y hembras (n = 34). De acuerdo a la edad se dividieron en 3 grupos: 3-5 años (n = 14), 5-15 años (n = 83) y >15 años (n = 6). Los resultados son expresados como porcentajes simples. El efecto de las variables sexo y edad fue analizado mediante la prueba exacta de Fisher con un nivel de significancia de p < 0,05. La prevalencia total de estereotipias clásicas fue 6,8% (1,94% aerofagia, 0,98% balanceo y 3,88% paseo circular en pesebrera). No se encontró diferencias estadísticas asociadas a la edad y sexo. Los resultados sugieren que los caballos chilenos presentan una prevalencia normal de estereotipias clásicas y que el paseo circular en pesebrera es la más frecuente en caballos de esta raza.Palabras clave: aerofagia, balanceo, paseo circular en pesebrera, equino, conducta estereotipada. ABSTRACTIn Chile, there have been two studies on classic stereotypic behavior in Chilean horses breed. The objective of the study was to determine the prevalence of classic stereotypies in Chilean horses stabled of the counties of Pinto and Coihueco, Biobío Region, Chile, and its association with sex and age. All Chilean horses registered and stabled in both counties were studied (n=103). Presence or absence of classic stereotypies (crib-biting, weaving and box-walking) was determined by direct observation of 20 min per hour for 4 hours. Data were analyzed dividing horses by sex into three groups: stallions (n = 36), geldings (n = 33) and mares (n = 34). Based on their age, they were divided into three groups: 3-5 years old (n = 14), 5-15 years old (n = 83) and >15 years old (n = 6). Results were expressed as simple percentages. The effects of age and sex were analyzed statistically by Fisher's exact test with a significance level at 0.05. Total prevalence of classic stereotypies was 6.8% (1.94%

“…Thus, in modern husbandry systems, single box housing prevails where horses experience both social isolation and confinement. The prevalence of weaving especially has been shown to relate to lack of social contact (Benhajali et al, 2010;Cooper et al, 2000), and a mirror or a poster of a horse have proved to diminish the frequency of this undesirable behaviour (McAfee et al, 2002). Social deprivation also leads to aggressive behaviours when horses are confronted again to conspecifics, and to undesirable behaviours at work (e.g.…”

Horses are highly social animals that have evolved to live in social groups.However, in modern husbandry systems, single housing prevails where horses experience social isolation, a challenge-to-welfare factor. One major reason for this single housing is the owners' concerns that horses may injure each other during aggressive encounters. However, in natural conditions, serious injuries due to aggressive encounters are rare. What could therefore explain the claimed risks of group living for domestic horses? Basing our questioning on the current knowledge of the social life of horses in natural conditions, we review different practices that may lead to higher levels of aggression in horses and propose practical solutions.Observations of natural and feral horses mostly indicate a predominance of low frequencies and mild forms of aggression, based on subtle communication signals and ritualized displays and made possible by group stability (i.e. stable composition), dominance hierarchy and learning of appropriate social skills by young horses. Obviously, adults play a major role here in canalizing undesirable behaviours, and social experience during development, associated with a diversity of social partners, seems to be a prerequisite for the young horse to become socially skilled.Given the natural propensity of horses to have a regulation of aggression in groups, the tendency to display more aggression in groups of domestic horses under some management practices seems clearly related to the conditions offered. We therefore review the managing practices that could trigger aggressiveness in horses. Non social practices (space, resource availability) and social practices (group size, stability of membership, composition and opportunities for social experiences during development) in groups of domestic horses are discussed here.2 Finally, we propose simple practical solutions leading to more peaceful interactions in groups of domestic horses, based on the knowledge of horses' natural social life which therefore should be enhanced (e.g. ensuring roughage availability, favouring group stability,, introducing socially experienced adults in groups of young horses;…). The state of the art indicates that many questions still need to be answered. Given the importance of the associated welfare issues and the consequences on the use of horses, further research is required, which could benefit horses… and humans.
