Title Unwanted oral investigative behaviour in horses: A note on the relationship between mugging behaviour, hand-feeding titbits and clicker training Type Journal Article
Year (down) 2010 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 127 Issue 3-4 Pages 104-107

Abstract Unwanted oral investigative in horses has been anecdotally attributed to the practice of hand-feeding. Fears over such behaviour developing as a consequence of using food rewards, for example in clicker training, have been implicated as a common reason for not employing food-based positive reinforcement training techniques. This study used data generated as part of a larger research project, and explored associations between five common oral investigative behaviours and the practices of hand-feeding and clicker training. Data were from a convenience sample of UK leisure horse owners using two self-administered Internet surveys. Ninety-one percent of respondents reported giving their horse food by hand and this practice was significantly associated with three of the five oral investigative behaviours, licking hands (P = 0.006), gently searching clothing (P < 0.001) and roughly searching clothing (P = 0.003). Nipping hands and biting clothes were not associated with hand-feeding, suggesting that risk factors for these behaviours originate outside of this practice. Clicker training techniques were employed by 14% of respondents and their use was not associated with the incidence of any of the five oral investigative behaviours. These findings suggest that horse owners should not be deterred from using food-based positive reinforcement techniques with their horses, as fears that this practice will result in unwanted oral investigative behaviours from their horses appear unfounded.

Abstract

The aim of this thesis was to investigate whether specific anecdotal concerns related to keeping horses in groups are supported by science and, if so, provide scientifically based recommendations that could be implemented in practice.

The aim of studies I and II was to identify methods for mixing unfamiliar horses that could minimise aggressive interactions and associated risk of injury. Results of study I revealed that pre-exposure of young horses in neighbouring boxes tended to lower contact-aggression (e.g. kicks, strikes) and biting behaviour in particular was reduced when the same pair of horses subsequently met in a paddock. This was not found when older horses were mixed (study II). Aggressive behaviour received by a new horse was not significantly different in meetings when it met one other horse compared to meeting two unfamiliar horses at the same time.

Removing a horse from a group of four in study III was generally unproblematic. Most horses approached the handler when she was catching the horse and while standing with it in the middle of the paddock. Thus, potential risk may be higher in situations when the handler remains relatively stationary, as other horses of the group have time to approach. Rank did not influence the number of horses following to the paddock gate and interactions between horses were rare.

Since horses naïve to social separation may be more difficult to handle away from the group, the objective in study IV was to investigate whether the initial presence of a companion horse would modify responses to separation. Results revealed no significant differences in heart rates and the number of training sessions required when the horses were subsequently trained in the absence of the partner compared to horses trained alone from the start.

In summary, results give little support for the original areas of concerns about mixing and separating horses. Risk of injury to both horses and humans should not be overestimated when handling horses in groups, but being aware of potential risk situations and being able to react accordingly is likely to increase horse welfare and human safety.

Title Effect of housing conditions on activity and lying behaviour of horses Type Journal Article
Year (down) 2010 Publication Abbreviated Journal animal
Volume 4 Issue 5 Pages 792-795
Keywords lying, behaviour, activity, equine, housing
Abstract Housing conditions for horses impose various levels of confinement, which may compromise welfare. Lying behaviour and activity can be used as welfare indicators for domestic animals and rebound behaviour suggests a build-up of motivation resulting from deprivation. The objective of this study was to determine if activity and lying behaviour of horses are affected by housing conditions and to investigate the occurrence of rebound behaviour after release from confinement. Eight horses were subjected, in pairs, to each of four experimental treatments; paddock (P), fully stabled (FS), partly stabled (PS) and yard (Y). Each horse received 6 days acclimatisation prior to the 24 h recording period. Time spent in lying and activity were electronically recorded using a tilt switch and motion sensor connected to a data logger worn on the horse's left foreleg. Time spent active during the first 5 min of release from stable to paddock in the PS treatment (days 1 and 5) and at the same time of day in the P treatment was used as a measure of rebound behaviour. Effect of housing conditions on total time spent active was highly significant (FS = 123 s, PS = 158 s, Y = 377 s, P = 779 s, P < 0.001). Housing conditions did not significantly affect total time spent lying (P = 0.646). Horses were significantly more active, compared with baseline paddock behaviour, on release from stabling on both days 1 (P = 0.006) and 5 (P = 0.025) of PS treatment. These results suggest that activity patterns of horses, but not lying behaviour, are affected by the housing conditions tested and that rebound activity occurs in horses after a period of confinement.

Title Long-term memory for categories and concepts in horses (Equus caballus) Type Journal Article
Year (down) 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 (down) 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.

Title Stimulus discrimination by horses under scotopic conditions Type Journal Article
Year (down) 2009 Publication Behavioural Processes Abbreviated Journal Behav. Process.
Volume 82 Issue 1 Pages 45-50
Keywords Discrimination learning; Equine; Horse; Night vision; Scotopic vision
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 (down) 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
Year (down) 2009 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 121 Issue 2 Pages 140-147
Keywords Stereotypic behaviour; Crib-biting; Modified Forssell's operation; Cribbing collar; Equine welfare; Stress coping
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.

Title Human-horse interactions: Where are the behaviorists in 2008? Type Conference Article

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 (down) 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.
