“…However, since poor correlations between heart rate, the latency to break, and anxiety scores were found in Phase I. This could indicate that assessing equine anxiety trait in the presence of a human handler may result in misleading outcomes, as suggested by McCall et al [10]. Partial correlation coefficients shown in Table 2 support this view.…”

“…Visser et al [24] reported that heart rate during exposure to a novel object was correlated with riders' rating scores on items such as 'spooky' and 'sensitive to disturbance'. McCall et al [10] carried out a novel object test and an isolation test with or without the administration of a tranquilizer. They concluded that heart rate reflected the reactivity of the horse, but behavior parameters were not consistently ranked in the two behavior tests.…”

“…To measure the reliability and validity of these tests, researchers have performed repetitive tests using the same horses [23,25], subjected the same horses to different behavioral tests [8,10,22,26], and in some cases measured differences when subjects were or were not tranquilized [10]. In this study, we examined the associations between results obtained from behavioral tests and anxiety scores assessed by caretakers to determine which parameters were most closely associated with equine anxiety trait.…”

“…Some researchers have assessed equine anxiety based on changes in behavior, as well as autonomic and endocrine functions, in response to various stimuli [e.g., 10,26]. Heart rate [25] as well as behavioral parameters such as exploring novel object and snorting [23] were shown to be significantly consistent within individual horses when the results were compared among repeatedly conducted novel environment tests.…”

ABSTRACT. The aim of the study was to determine parameters reflecting equine anxiety trait by comparing results obtained in a behavior test and an anxiety score assessed by familiar caretakers in response to a questionnaire. In the behavior test, horses were individually led into a novel room by their caretakers and loosely tethered to decrease excessive movement using the common cross-tying technique with two leads and breakable plastic cords. The horses initially remained with their caretaker for 2 min; the caretaker then left and the subject animal was left alone for 2 min. The latency to break the plastic cords, heart rate, the number of steps and pawings were recorded. When the horses were left alone, most parameters changed significantly and some showed sexual differences. A correlation analysis revealed that anxiety score assessed by caretakers showed a negative correlation with the latency to break the plastic cord and a positive correlation with heart rate only when horses were isolated. These two were suggested feasible parameters for assessing the anxiety trait of unfamiliar horses. Both the behavioral results and the anxiety scores also indicated that females were more anxious than males. Our results suggest that it would be a useful strategy for assessing other temperament traits as well to combine behavior tests with a questionnaire survey.

“…Although no significant association was found between each haplotype and equine anxiety trait in 67 thoroughbred horses, this anxiety trait should be given priority among equine temperament traits to be investigated, as it can be assessed more reliably and accurately than other temperament traits using either questionnaires or behavior tests [9][10][11]17]; this is in addition to the importance of the anxiety trait in various human-horse relationships.…”

ABSTRACT. Equine anxiety trait is considered an important temperament in various situations, including riding, training, and daily care. This study examined the polymorphism of the equine serotonin transporter (SLC6A4) gene as a candidate genetic element influencing equine anxiety trait. The sequence of the coding region of this gene was highly homologous with those of other mammals, and four single nucleotide polymorphisms were found by comparing the sequences of ten genetically unrelated thoroughbred horses. Radiation hybrid mapping revealed that this gene was located 26.92 cR from neurofibromin 1 on ECA 11. Using two-year-old thoroughbred horses (n=67), the association of these polymorphisms with the anxiety trait was examined, but no significant association was identified between each haplotype of the serotonin transporter gene and the anxiety score. KEY WORDS: anxiety, equine, serotonin transporter.
