Factores de riesgo para la presentación de conductas no deseadas en equinos de deporte en ChileRisk factors for the presentation of undesired behaviours in sport horses in Chile
SUMMARYBehaviour alterations are considered as cause and symptom of poor animal welfare. Generally they have been associated to suboptimal husbandry practices and intrinsic factors of horses. The aim of this study was to indentify risk factors for the presentation of behaviour alterations in sport horses. The information of 1,529 equines was compiled from three databases, the individuals were classified in groups according to the type of behaviour in "locomotor" and "oral". Environmental and intrinsic conditions were evaluated as possible risk factors for the presentation of oral behavioural alterations through a multiple logistic regression model; a significance level of P < 0.05 was considered. A total of 188 individuals with behavioural alterations were registered, and thirteen of them presented more than one alteration. A total of 90 locomotor and 111 oral undesired behaviours were registered; the most frequent undesired behaviours were box-walking and crib-biting/wind-sucking for each group respectively. In the case of locomotor behaviours no risk factors statistically significant were found, however a forage percentage ≥ 60% in the ration was identified as a protective factor, as was belonging to the Chilean breed. On the other hand, for the oral behaviours, a forage percentage ≥ 60% was identified as a statistically significant risk factor, and the Thoroughbred breed was identified as protective factor in the logistic regression. Some management factors and intrinsic characteristics of the animal may increase or decrease the presentation of these behaviours in sport horses, these factors should be considered when designing an equine production system in order to maintain their welfare.Key words: equine, behaviour, animal welfare, risk factors.
RESUMENLas alteraciones conductuales son consideradas causa y síntoma de un problema de bienestar animal. Generalmente se han asociado a condiciones de estabulación o manejo subóptimas, y a factores intrínsecos del animal. El objetivo del estudio fue identificar factores de riesgo para la presentación de alteraciones conductuales en equinos de deporte. Se recopiló información de 1.529 equinos de tres bases de datos y se clasificaron en grupos según el tipo de conducta no deseada: locomotor y oral. Las condiciones ambientales e intrínsecas fueron evaluadas como posibles factores de riesgo para la presentación de alteraciones conductuales mediante un modelo de regresión logística multivariado, estableciéndose un nivel de significancia de P < 0,05. Se registraron en total 188 individuos con alteraciones conductuales, de los cuales trece presentaron más de una. Se presentaron 90 conductas locomotoras y 111 orales, siendo la caminata estereotipada y la aerofagia las más frecuentes en cada grupo. Para el caso de las conductas de tipo locomotor no se encontraron factores de riesgo estadísticamente...
La présente liste des types compte 130 taxa répertoriés par ordre systématique des ordres selon la classification d' EscHMEYER (1990), et alphabétiques des noms de genres, espèces et sous espèces, selon la nomenclature originale. Elle ne mentionne que les types primaires (holotypes, lectotypes, néotypes et syntypes), sans autres indications que la catégorie de type, le numéro MHNG et le nombre de spécimens. Les espèces mentionnées par Mahnert (1976) sont précédées d'un astérisque. De même que le catalogue des types d'amphibiens et de reptiles possède une version plus détaillée sur serveur électronique (Schätti & Perret 1997b), cette liste succincte est publiée conjointement à la création d'un accès Internet au catalogue complet des types (y compris paratypes et paralectotypes), détruits ou disparus inclus, avec mention détaillée des localités, dates de capture et récolteurs. Des précisions concernant leur historique sont ajoutées en remarques. Ce catalogue, régulièrement mis à jour, est accessible à l'adresse:
