Equine self-mutilation syndrome (57 cases).
- Journal Article
Summary
This research article looks at self-mutilating behavior in horses, gathering information through questionnaires from owners of such horses. They examined information about the horses’ health history, the signs of the behavior, and any management or treatment tactics used. Various breeds were included in the study and the horses were of varying genders and ages, though the syndrome tended to develop earlier in life. None of the investigated environmental and management factors could be definitively linked to the disorder. However, some treatments, such as castration and medication, were found to have a positive impact. The self-mutilating behavior in these horses seemed to have similar qualities to human Tourette’s syndrome.
Research Methodology:
- The researchers distributed questionnaires to owners who believed their horse demonstrated self-mutilating behavior. These questionnaires were designed to gather data on signalment (the description of the horse), clinical history, clinical signs, and management and treatment strategies used.
- Out of the 59 replies received from owners, 2 were removed from the analysis, since an organic cause for the behavior was identified in those instances.
Clinical Findings:
- The study sample comprised various horse breeds. Among the 57 horses studied, 20 were stallions, 31 were geldings, and 6 were mares.
- The horses tended to develop self-mutilating behavior before they reached sexual maturity.
- The syndromic behavior ranged from glancing or bitting at the flank or pectoral areas, bucking, kicking, vocalizing, rubbing, spinning, or rolling.
Environmental and Management Factors:
- The researchers examined several management and environmental factors in the study. However, none of these factors were definitively linked to the expression of the disorder.
Interventions and Treatments:
- Several strategies were studied to manage and treat the self-mutilating behavior.
- Castration was one such strategy that brought about improvement in 7 of the 10 stallions that were treated.
- The use of medications and changes in the management approach also resulted in the reduction, or in some cases prevention, of the self-mutilating behavior.
Comparison with Human Tourette’s Syndrome:
- Toward the end of the study, the researchers suggested a similarity between the equine self-mutilation syndrome and human Tourette’s syndrome, based on the behavior patterns observed.
