Abstract | This presentation will include commentary on work presented at this meeting as representative of the rapidly growing body of equine behavior science evidence relevant to human-horse interaction and the welfare of domestic, feral, and wild horses. A substantial literature has accumulated detailing the behavior patterns of wild and feral equid populations, and to some extent the behavior of horses in various domestic environments. Professor Klingel“s and Professor Houpt”s work, begun nearly 40 years ago, continues to inspire colleagues around the world to qualitatively and quantitatively describe behavior of equids in a variety of environments. Several examples of the importance of this type of work to human-horse interaction and horse welfare are evident in throughout the meeting. It forms the basis for assessing the disturbance of behavior in wildlife management projects such as fertility manipulations (Hopkins; Ransom & Cade) or species reintroduction (Kaczensky et al). Study of the apparent variability in observations among the populations will lead to a better understanding of environmental and other factors, which will have fruitful application to welfare of horses both in domestic and natural environments. Unfortunately, this work always brings to mind what I perceive as a nagging threat to horse welfare and quality of human-horse interaction is misinformation concerning natural horse behavior. Natural horse behavior seems to be of great general interest, but unfortunately inaccuracies and misinterpretations are pervasive in popular “horse culture” and continue to be a conspicuous influence on management and training of domestic horses. Unfortunately, this misinformation often makes its way and influences equine education, both lay and equine science/veterinary education. Comparative observational study of behavior of horses in all settings by trained behaviorists, along with research designed to address purported implications for management of domestic horses, along with initiatives to transfer knowledge to educators at all levels should be encouraged. Included in this meeting is considerable work addressing questions of domestic management practices such as forced weaning, transportation, stabling, and arbitrary grouping and regrouping of horses. This adds to a growing body of applied physiology and behavior research that has established trained behaviorists as a critical resource on teams making decisions on humane management. Also well represented in work presented at this meeting is the exploration of cognition, perception, and temperament in horses. It is personally pleasing to see examples of direct investigation of the ability of the horse to respond to subtle human posture and gesture, which for many of us has represented just annoying possible confounders of earlier cognition studies. Behaviorists trained in perception and learning will no doubt contribute enormously to this exciting area of investigation. |

Title | An overview of educational offerings in equine science and -management in Canada | Type | Conference Article | ||
Year | 2008 | Publication | IESM 2008 | Abbreviated Journal | |
Volume | Issue | Pages | |||
Keywords | Equine science studies, BSc degree, diploma, certificate, University of Guelph | ||||
Abstract | Canada has a variety of educational offerings in equine management at the diploma and certificate level offered by universities and colleges, as well as by industry supported centres. However, it was not until 2007 that the first degree-based program in equine science was launched. Offered by the University of Guelph, the Bachelor of Bio- Resource Management – Equine Management program is designed for students who do not intend to pursue post-graduate studies and are strongly focused on securing employment that makes use of the knowledge acquired in their bachelor's degree. The courses in the BSc-program include basic natural sciences as well as equine-specific courses with a focus on management of equine related businesses and events. Diploma and certificate programs usually include only specifically equine-related courses e.g. in anatomy and physiology, health, business, facility management and nutrition. All diploma and certificate programs, and to a slightly lesser extent the BSc program, have a strong focus on applied learning with the intent to provide highly trained workers for the industry. Unique in Canada are the entirely online-taught Diploma in Equine Studies, the Certificate in Equine Business Management and the Equine Science Certificate offered by Equine Guelph and the University of Guelph"s continuing education. Students of these programs have access to a virtual classroom via the internet, and therefore access to instructors and guest speakers from the industry throughout the course. The Canadian certificate programs typically take one year (two semesters), the diploma programs two years (four semesters), while the BSc program takes four years (eight semesters). The BSc program requires approximately 2000 hours of in-class time plus roughly twice the amount spent on assignments and studying, totalling to an overall workload of roughly 6000 hours. Most programs require the completion of Grade 12 or equivalent for admission, and in all programs a background and experience with horses is not required for admission, however it is usually deemed beneficial. Career options for BSc-graduates include barn management, riding instructor or coach, professional rider, judge, steward, course designer, equine-assisted therapy, veterinary assistant, event manager, nutrition consultant, retail sales in tack and equipment, equine sales and marketing, agriculture extension services, college lecturer, consultant and technical advisor, and media relations. Career options for the diploma and certificate program graduates generally include similar areas, with a focus on hands-on work and direct interaction with horses such as employment as grooms, trainers and barn managers. | ||||

Title | Is modified Forssell"s operation superior to cribbing collar in preventing crib-biting in horses? | Type | Conference Article | ||
Year | 2008 | Publication | IESM 2008 | Abbreviated Journal | |
Volume | Issue | Pages | |||

Abstract | Crib-biting (wind-sucking) might be a coping response of the horses to the challenges of uncontrolled environmental events. Prevention of this stereotypic behaviour evokes physiological responses consistent with increased stress. Reducing the incidence of cribbiting, however, is important in order to prevent undesirable physical and behavioural consequences (tooth erosion, altered gut function, gastric inflammation/ulceration, colic, etc.). Common treatment of crib-biting is the application of a cribbing collar, which limits the flexion of the neck making this stereotypic movement uncomfortable and difficult. Another method, the modified Forssell“s operation, is becoming more and more popular amongst the horse owners. It is based on the removal of the muscles used in crib-biting (m.omohyoideus, m.sternohyoideus, m.sternothyrohyoideus) and the ventral branches of the spinal accessory nerves. Surveys on the success of this surgical procedure have revealed inconsistent results, and, contrary to the cribbing collar, its effect on the stress level have not been studied either. The aim of our study was to determine whether the modified Forssell”s procedure is superior to the cribbing collar treatment. Differences in stress management was tested by a crib-biting provoking test, in which surgically treated horses, crib-biting horses, crib-biting horses with cribbing collar, and normal horses (those showing no stereotypies), altogether 56 horses were compared. In this test, a food bucket had been placed out of the reach of the animal, from which titbits were given 3 times. Behaviour and heart rate variability (HRV) of the horses were recorded and analysed throughout the test. Hypotheses were tested by linear mixed model. According to our results, both prevention methods (collar or surgery) inhibited crib-biting successfully though not totally. Regarding behaviour and heart rate variability, horses prevented from crib-biting (by collar or surgery) differed significantly from crib-biting and normal horses but not from each other. Normal horses were usually trying to reach the food-bucket while present and were standing still afterwards, whereas the other three groups had not really made efforts to reach the bucket, spent less time with resting, and performed or tried crib-biting. During the stress-test, normal and crib-biting horses had shown good stress-adaptation to the challenge since their HRV, after an initial increase, returned to the basal value by the end. On the contrary, HRV of the two prevented groups remained elevated and showed large oscillations throughout. They had not found a successful coping behaviour either. Our results suggest that since prevention may significantly increase distress, the treatment in itself, without changing the motivation of the horse to perform the replacement behaviour – it seems to be unsatisfactory and insufficient. After prevention the motivation of the horse to perform crib-biting should be addressed. In addition, considering that prevention by collar and surgery had not resulted in any significant behavioural or physiological differences, the superiority of the modified Forssell"s procedure might be questioned. However, the surgery might be recommended if treatment with collar is ineffective. |

Abstract | Target group: Biologists, Psychologists, Veterinarians and Professionals Meeting target: Because the last international meeting on Equine Science took place a couple years ago, there is an urgent need for equine scientists to exchange scientific knowledge, coordinate research provide knowledge for practical application, and discus research results among themselves and with professionals who work with horses. Additionally, dialog concerning the coordination of the study “Equitation Science” in Europe is urgently needed. Coordination and cooperation shall arise from the meeting, enrich the research, and advance the application of scientific knowledge for the horses` welfare. |

Title | Equal Outcomes with and without Human-to-Horse Eye Contact When Catching Horses and Ponies in an Open Pasture | Type | Journal Article | ||
Year | 2008 | Publication | Journal of Equine Veterinary Science | Abbreviated Journal | |
Volume | 28 | Issue | 5 | Pages | 309-312 |
Keywords | Horse handling; Horse management; Eye contact; Interspecies interactions; Equine behavior | ||||
Abstract | Each of 104 horses and ponies was approached for catching at pasture by the same human handler in a standard manner, either maintaining human-to-animal eye contact (EC+; n = 51) or avoiding eye contact (EC-; n = 53). A subset of 74 of these subjects were reevaluated 3 weeks later under similar standard conditions except with the eye contact condition opposite to that used in the first round. Nonparametric statistical methods were used to evaluate between subjects (round 1, n = 104) and within subjects (rounds 1 and 2, n = 74) comparisons of successful or unsuccessful catching outcome with EC+ and EC-. Catching outcomes were similar with eye contact condition. Although this study represents a single handler at one study site, results suggest that human-to-horse eye contact may not be an important influence on catching pastured horses. Certainly, further work is needed to better understand the role of eye contact in horse handling. | ||||

Title | Long-term memory for categories and concepts in horses (Equus caballus) | Type | Journal Article | ||
Year | 2009 | Publication | Animal Cognition | Abbreviated Journal | Anim. Cogn. |
Volume | 13 | Issue | 3 | Pages | 451-462 |
Keywords | Horse – Long-term memory – Concept – Categorization – Discrimination – LCD display – Equine | ||||
Abstract | Three horses (Equus caballus) with a history of performing cognitive tasks including discrimination learning, categorization, and concept use were tested to evaluate their long-term memory (LTM) in three experiments. In addition, use of LCD multi-displays for stimulus presentation was incorporated into cognition testing protocol for the first time with horses. Experiment 1 tested LTM for discrimination learning that originally occurred 6 years earlier. Five sets of stimuli were used and the two horses tested showed no decrement in performance on four of the sets; however, both horses did score below chance on one set. Experiment 2 examined long-term categorization recall 10 years after horses had demonstrated the ability to make stimulus selections based on shared characteristics within a given category. The horse tested for LTM after the decade-long interval immediately and consistently applied the previously learned categorization rule to not only familiar but also novel sets of stimuli. Experiment 3 tested another horse for LTM for a relative size concept. This horse had originally demonstrated concept rule use in order to select stimuli based on their relative size to one another. More than 7 years later and without further training, this horse reliably applied the previously established size concept to both familiar and novel sets of stimuli. These findings are the first reports of long-term categorical and conceptual memory in horses and are consistent with observations of domestic and wild horses, which indicate that behavioral and ecological events may be remembered for long periods of time. These studies also demonstrate the adaptive nature of horses with regard to their ability to generalize over several different testing conditions. | ||||

Title | Role of Diet and Feeding in Normal and Stereotypic Behaviors in Horses | Type | Journal Article | ||
Year | 2009 | Publication | Veterinary Clinics of North America: Equine Practice | Abbreviated Journal | Clinical Nutrition |
Volume | 25 | Issue | 1 | Pages | 167-181 |
Keywords | Equine behavior; Diet; Crib-biting; Stereotypy; Weaning; Tryptophan; Insulin | ||||
Abstract | This article reviews the effects of diet on equine feeding behavior and feeding patterns, before considering the evidence that diet affects reactivity in horses. A growing body of work suggests that fat- and fiber-based diets may result in calmer patterns of behavior, and possible mechanisms that may underpin these effects are discussed. In contrast, there is little evidence that herbal- or tryptophan-containing supplements influence equine behavior in any measurable way. The role of diet in the development of abnormal oral behaviors, particularly the oral stereotypy crib-biting, is also reviewed, and suggestions for future work are presented. | ||||

Abstract | Scotopic vision in horses (Equus caballus) was investigated using behavioral measurements for the first time. Four horses were tested for the ability to make simple visual discriminations of geometric figures (circles and triangles) under various brightness levels within an enclosed building. Measurements of brightness ranging from 10.37 to 24.12 magnitudes per square arcsecond (mag/arcsec2; in candelas per square meter--7.70 to 2.43E-05 cd/m2) were taken using a Sky Quality Meter. These values approximated outdoor conditions ranging from twilight in open country to a dark moonless night in dense forest. The horses were able to solve the discrimination problems in all brightness settings up to 23.77 mag/arcsec2 (3.35E-05 cd/m2). Moreover, they easily navigated their way around obstacles located within the testing area in extremely dim light (>23.50 mag/arcsec2; 4.30E-05 cd/m2), which were in conditions too dark for the human experimenters to see. These findings support physiological data that reveal a rod-dominated visual system as well as observations of equine activity at night. | ||||

Title | Social interactions of unfamiliar horses during paired encounters: Effect of pre-exposure on aggression level and so risk of injury | Type | Journal Article | ||
Year | 2009 | Publication | Applied Animal Behaviour Science | Abbreviated Journal | Appl. Anim. Behav. Sci. |
Volume | 121 | Issue | 3-4 | Pages | 214-221 |
Keywords | Equine; Behaviour; Welfare; Mixing; Housing; Wounds | ||||
Abstract | Group housing of horses is not widely applied in practice despite the welfare advantages of keeping animals socially rather than individually. In particular, concerns have been raised about the possible increased risk of injury and how to introduce a new horse into an established group. This study investigated two hypotheses: (1) pre-exposure of young horses in neighbouring boxes reduces the frequency of aggressive interactions when the same horses are subsequently put together in a paddock compared to horses without this previous box experience, (2) the occurrence of aggressive behaviour, in particular contact aggression in the paddock can be predicted after observing the horses' social interactions in neighbouring boxes. Danish Warmblood mares (n = 20), 2 years old, were kept in two groups of 10 horses. In total, 60 encounters were arranged whereby each horse was confronted pair-wise with six horses from the other group, three according to each treatment: treatment I--box (B) and subsequent paddock meeting (BP), and treatment II--only paddock meeting (P). Horses met in neighbouring boxes for 5 min and together in the same paddock for 10 min. The frequencies of aggressive and non-aggressive interactions were analysed from video recordings. Total aggression levels between BP and P did not differ, but [`]contact aggression', i.e. bite, kick, strike, push, tended to be lower in BP compared to P (median BP = 1, P = 2; p = 0.083) and there were less bites in BP than P (median BP = 0, P = 1; p = 0.050). Frequencies of [`]non-aggressive' interactions, e.g. friendly approach, nasal sniff, were lower in BP than P (median BP = 2.5, P = 10; p < 0.01). Results further revealed that [`]bite threat' performed in boxes correlated with [`]contact aggression' in the paddock (r = 0.46, p = 0.011). In conclusion, pre-exposure of young horses in neighbouring boxes may reduce [`]contact aggression', especially biting, in the paddock and [`]bite threat' shown in boxes may help to predict contact aggression when horses are later turned out together. The reduced non-aggressive interactions in the paddock in the BP test were probably a consequence of horses having exchanged these behaviours in the preceding B test. Exposing young horses in boxes next to each other may be a helpful tool before mixing them because horses meet in a safe environment that could assist in reducing the type of aggression where horses are most at risk of being injured. | ||||

Title | The effect of a feeding stress-test on the behaviour and heart rate variability of control and crib-biting horses (with or without inhibition) | Type | Journal Article | ||

Abstract | Crib-biting is a form of oral stereotypy affecting 4-5% of horses. Once fixed, crib-biting is difficult to eliminate by behaviour therapy, however, its performance can be inhibited by collar or surgery treatment (modified Forssell's procedure). Although surgical intervention is widespread, the effects on stress coping in horses have not been studied. In the present study we evaluated changes in behaviour response and heart rate variability in 9 control, 10 crib-biting, 10 collar and 11 surgically treated horses in a feeding stress-test, in which a feeding-bowl was placed in front but out of the reach of the horses, from which tidbits were given 3 times. We found that stress triggers high oral activity, mainly cribbing in crib-biting horses, elevates other forms of oral activities in the inhibited groups and does not affect oral activities of controls. Instead of performing oral activities, control horses tended to target an unavailable feeding-bowl by pawing or head-tossing. Changes in stress level were indistinguishable in controls and crib-biters as heart rate variability returned to baseline values in both groups. In contrast, horses inhibited to perform crib-biting showed elevated stress level throughout the test period. Our results suggest that crib-biting may develop to cope with stress, and such coping function diminishes when inhibited. | ||||
