| Abstract | Horses" reactions to normal environmental and training situations play an important role the human-horse relationship. These demands on horses can either lead some individuals to withdrawal, immobility or aggressive defence. However, the reaction to such situations varies greatly among horses, which is reflected in individual differences in sympathetic, parasympathetic and muscular reactivity. The observable behavioural responses of the horses seem to be qualitatively related to the internal state of physiological arousal. In future it should be possible to identify behavioural signs which really do reflect internal states of the autonomic nervous system to provide general advice concerning human handling and training in view of reducing stress in horses. For these purposes, we have determined responses of the vegetative nervous system based on variation in skin potential, skin resistance and electromyogram using non-invasive real-time measurements. All these parameters can be measured by a SMARD-Watch-System (System of non-invasive Measurement and Analysis for Regulatory Diagnostics), which can be externally attached to the horses using a harness. The physiological data will assess using a time series analysis. Thereby the changes in the regulatory processes in each of the three physiological systems can be determined in detail. Based on this analysis characteristic behaviour patterns will be analysed by the variability of the regulatory processes. According to temporary shifts in regulatory processes, stable and unstable regulation states will be determined. Depending on the proportions of unstable regulation processes during and after external threat, four types of regulation can be defined: the Control, Cope, Compensate and Non-cope- type. Defined time-windows, for example a ten minutes lasting pre- and post-test phase and a ten or twenty minutes lasting time-window for the execution of the specific stimulus have to be chosen to decide these regulation types. These four regulation types and the preferred individual behaviour strategies have to be compared to evaluate the relative frequency of occurrence of a behaviour strategy depending on responses of the vegetative nervous system. In view of validating behavioural indicators of emotional reactivity, the aim of this new method is to characterize individual differences in the behavioural and physiological responses of horses to normal environmental and training stimuli. Evidence is provided by human and animal data that the non-invasive real-time measurement of the vegetative nervous system based on variation in skin potential, skin resistance etc. is a promising approach for evaluating stress and emotional states in vertebrates. It will be explained that the chronobiological evaluation of physiological parameters has the potential to contribute much to our understanding and assessment of the underlying physiological processes of stress responses in horses. |

| 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. | ||||

| Abstract | The MSc-program in Equine Science, initiated in 2006 in response to needs for scientific support of the growing equine sector, is the first of its kind in Germany. It is offered by the Faculty of Agriculture Science, Department of Animal Breeding and Genetics at the University of Göttingen, Germany, however courses are delivered in cooperation with the University of Veterinary Medicine Hannover and the German Equestrian Federation (FN). The courses are concerned with the scientific basis of horse breeding, husbandry, nutrition, physiology, behaviour, and health, as well as with aspects of business administration and management of equine facilities and their impact on society, economy and the environment. Courses are delivered in German and – in the case of some guest speakers – English language in form of lectures, laboratories, seminars, group-projects, internships and a combination thereof. Currently, the program is limited to 30 students per year and requirements for admittance are a BSc (or equivalent) degree in animal science or related subjects. However, graduates of programs e.g. in business administration, economics, or veterinary or law schools, are also accepted. The program takes two years (four semesters), and requires the completion of 120 European Credit Transfer System points, i.e. a workload of approximately 3000 hours. This timeframe includes the preparation of a thesis based upon research in topics related to equine science, demonstrating the candidate"s capacity for original and independent work. Further information about the program can be obtained from the official website: http://www.pferde.uni-goettingen.de . Career options for graduates include equine facilities management, consulting services, agriculture extension services, feed industry, agricultural ministry and related civil service, universities and research institutions. | ||||

Are horses (Equus caballus) sensitive to human attentional states? | Type | Conference Article | ||
| Year | 2008 | Publication | IESM 2008 | Abbreviated Journal | |
| Volume | Issue | Pages | |||
| Keywords | Horses; Attentional state; Begging behavior | ||||
| Abstract | The ability to reliably detect what others are attending to seems important for social species to interact with their partners. Domestic horses (Equus caballus) have lived with humans for over five thousand years, hence they might have developed sensitivity to human attention. In the present study, we investigated whether horses would discriminate the situation in which a human experimenter could see them from the situation in which she could not. Specifically, we tested whether horses understand the role of eyes in human attentional states, produce more visual gestures when the experimenter can see their begging behaviors and produce more auditory or tactile gestures when she can not. We used with a slight modification the paradigm that previously yielded support for chimpanzee understanding of human attention (Hostetter et al. 2007). Twelve horses were offered food by the experimenter who showed various attentional states in front of them. We scored frequency of begging behaviors by the horses. In experiment 1, we set three kinds of condition: hand over the eyes, hand over the mouth and away. In the last condition there was only a food in front of horses, which was a control condition. The results showed that horses produced more auditory or tactile begging behaviors when the experimenter“s eyes were not visible than when her eyes were visible, but there was no difference in visual begging behaviors. In experiment 2, we set two kinds of condition: eyes closed and eyes open. The horses also produced more auditory or tactile begging behaviors when the experimenter”s eyes were closed than when they were open. However, there was no difference in visual begging behaviors. These results show that horses discriminate the situation in which humans can see from that in which humans can not. Of special interest, horses increased only auditory or tactile behaviors, not all types of communicative behaviors, when the experimenter could not see their begging behaviors. This result suggests that horses are sensitive to human attentional states. Moreover, horses may do recognize the eyes as an important indicator of whether or not humans will respond to their behavior and they may be able to behave flexibly depending upon human attentional states | ||||

Automatic feeding systems versus feeding stalls for horses kept in groups: visiting frequency, stress situations and risk of injury | Type | Conference Article | ||
| Year | 2008 | Publication | IESM 2008 | Abbreviated Journal | |
| Volume | Issue | Pages | |||

| Abstract | When keeping horses in run-out sheds, feeding stalls are usually recommended for individual feeding; which allows equine typical simultaneous eating. However, automatic feeding devices for hay and concentrates are being increasingly used, and these do not allow simultaneous eating. This research aims to compare visiting frequency, stress situations, and the risk of injury, in the area of automatic feeding systems with those at feeding stalls. The studies were carried out at 10 stables with feeding stalls and at 11 with automatic feeding systems for hay and concentrates. These stables were otherwise similar regarding the keeping of the horses and the management of the facilities. Each group consisted of 8 to 21 horses, with 260 horses taking part in total. Every group was observed for 6 sessions, each of 4 hours. These 6 sessions together made 24 hours, a complete day. Horses in stables with feeding stalls visited the feeding area (waiting area, the station, exit area) 45.5 ± 27.3 times on average in 24 hours, and in stables with automatic feeders for hay and concentrates, 93.1 ± 53.5 times. This difference was significant. Threatening behaviour, without risk of injury or with risk of injury, occurred significantly more frequently in stables with automatic feeders (9.6 ± 12.9 times and 4.2 ± 5.5 times respectively per 24 hours and horse) than in stables with feeding stalls (6.0 ± 10.4 times and 1.5 ± 3.3 times respectively per 24 hours and horse). The management of the stable, however, proved to have its most important influence on the behaviour of the horses. Displacement activities were observed in stables with feeding stalls 0.3 ± 1.0 times per horse and 24 hours and in stables with automatic feeders for hay and concentrate 12.9 ± 23.3 times. Situations that could cause either stress or injuries to the horses occurred in stables with feeding stalls within 24 hours per horse only 3.7 ± 13.1 and 1.3 ± 4.8 times on average respectively. Such situations were to be seen in stables with automatic feeder 17.0 ± 33.4 and 8.6 ± 15.3 times respectively per horse and 24 hours – clearly more often. We may therefore conclude that the more often the feeding area is visited, the more frequently threatening gestures without and with risk of injury occur. The same goes for the number of situations that may result in stress or injuries. Therefore to sum up it can be said that feeding in feedings stalls leads to less risk of stress and injuries compared with feeding by computer controlled systems. On the other hand, computer controlled systems have the advantage of stimulating the horses to move, which is very important for their health. While assessing this study it should be taken into account that there were very big individual differences between the horses. The result of the statistical evaluation was that the management of the stable has a decisive influence on the observed features. Therefore both feeding systems can be recommended, especially as the number of conflicts in the feeding area in all stables was relatively low and no injuries were observed in connection with the feeding. |

Behavioural patterns of pony foals after simultaneous and consecutive weaning | Type | Conference Article | ||
| Year | 2008 | Publication | IESM 2008 | Abbreviated Journal | |
| Volume | Issue | Pages | |||
| Keywords | |||||
| Abstract | In this study, the behaviour of Shetland pony foals after weaning was analysed. Foals were either weaned simultaneously (group SW; n=7) by removing all mares at the same time and leaving the foals as a group or foals were weaned consecutively (group CW; n=4) by removing one mare per day on consecutive days. Behaviour of the foals was observed 3 times per day (6:00-8:00, 12:00-14:00 and 18:00-20:00) from one day before weaning to 7 days (group SW) or 10 days (group CW) after removing the first mare. Vocalisation after removal mares was more frequent in foals weaned simultaneously (d 1: SW 66±37 per 2 hrs) than when mares were removed consecutively at one-day intervals (d1, i.e. removal of first mare: CW 3±2 per 2 hrs). In CW foals, vocalisation was most frequent on the day after removal of the last mare (day 5: 18±6 per 2 hrs), although it was lower than in SW foals on day 1 after weaning. Locomotor activity was highest in SW foals on days 1 and 2 after weaning (maximum 17±6 movements per 2 hrs, p<0.05 vs. CW: <2 movements per 2 hrs at all times). Frequency of defaecation increased to 7±1 per 2 hrs on day 1 after SW (p<0.05 vs. group CW), it was 3±2 per 2 hrs in group CW at the time 3 mares had been removed and was below 2 at all other times in both groups. The time, foals spent in lateral recumbency and in sternal recumbency was reduced to near zero during the two days following weaning (group SW) and the period during which mares were removed consecutively (group CW). Tactile contact between foals was increased in SW foals after weaning compared to CW foals during the period of consecutive weaning. Suckling on other foals increased in both groups for several days after weaning but did not differ between groups. No major changes over time or differences between groups were found for other behaviour parameters. Foals weaned simultaneously lost weight slightly but significantly (p<0.05) within two days after weaning (from 78±11 to 75±10) while no weight loss occurred in CW foals. In conclusion, SW elicited more pronounced behavioural changes than CW in pony foals. Consecutive weaning can be considered a more gentle method than SW and thus may be associated with lower risks and less stress for the foals. | ||||

Changes in heart rate and cortisol release during initial training of three-year-old warmblood sport horse stallions | Type | Conference Article | ||
| Year | 2008 | Publication | IESM 2008 | Abbreviated Journal | |
| Volume | Issue | Pages | |||
| Keywords | |||||
| Abstract | The first weeks of training in young sport horses have been suggested to represent a stressful period and training practises for horses have been questioned recently. So far, only limited data on the stress response of young horses to the initial training are available. Heart rate (HR) provides information on fitness of the horse but is also an indicator of stress or pain. Determination of cortisol metabolites in faeces is a non-invasive technique to determine a prolonged stress response. In our study, three-year-old warmblood sport horse stallions (n=8) were followed through a standardised 10-week classical training programme from lunging to first mounting of a rider and progressing to moderate work. Feed, housing and management were similar for all horses. HR was recorded with a mobile recording System (f810i, Polar, Kempele, Finland) fixed to a girth around the thorax of the horse and was monitored twice weekly from 30 min before to 30 min after training, i.e. including the training period. In addition, cortisol concentrations were determined in faecal samples collected three times daily. Overall basal HR before daily training was 39±2 (SEM) beats/min and mean values did not change significantly over the 10-week study period. Average HR during initial lunging (week 1) was 119±14 beats min and decreased to 95±5 beats/min in week 2. Due to individual variations this decrease did not reach statistical significance. Neither first mounting of a rider (89±10 beats/min) nor an increasing workload (e.g. week 8: 111±4 beats/min) were associated with prolonged increases in mean HR, but transient increases were recorded and the response to mounting of the rider differed markedly between stallions. After daily training, HR decreased rapidly but was slightly, although significantly (p<0.05, Friedman-test) higher than pre-work values (46±2 beats/min). Cortisol metabolite concentrations in faeces tended to decrease during the period of lunging, were not increased when the horses were first mounted by a rider but rose slightly with an increasing work load during the last 4 weeks of the 10-week training period. In conclusion, based on HR and faecal cortisol metabolite concentrations, the initial training of sport horse stallions in the classical German training system is not associated with major stress for the horse. The increase in HR during training is due to physical exercise itself and not associated with specific situations of the training programme.

Cognitive Tests in Equids (Equus caballus and Equus Asinus) | Type | Conference Article | ||

| Volume | Issue | Pages | |||
| Keywords | |||||
| Abstract | For ages horses and donkeys constituted the most important domesticated animals. Even though equids were often bred and kept in close proximity to humans, surprisingly little is known about their cognitive abilities. Traditionally, horses are not regarded as clever animals; common beliefs maintain that the horses“ behaviour is merely driven by conditioned-responses. Additionally, from an anthropomorphic point of view donkeys are believed to be ”stupid“ animals. Our study investigates the equids” ability to recover a hidden object. For this purpose the animal has to create and maintain a representation of the object and its location in space, from the moment in which it disappears from direct perception, till the moment in which it reappears. The knowledge about objects being entities that continue to exist even when they are no longer available for direct perception is refered to as the well known concept of “object permanence”. We primarly assessed the ability of Esperia's pony and donkeys to solve a Detour problem while employing an opaque “U-shaped” barrier. Each animal observed a food bucket moving and disappearing behind the barrier. Immediately after the object"s disappearance, the animal was released to search for the object. If it solved the task by detouring the barrier it was positively reinforced. The ability to retain in memory the hidden object as well as its spatial location was subsequently tested in the presence of two, rather than one, screens (Working Memory testing phase). The food bucket was made to move and hidden behind one of the two identical screens, while the animal was watching it. Following a pre-established delayed period of 10 sec, the animal was set free to look for the food. In such a test the detour problem is combined with the classical delayed-response task, which is in use for the comparison of memory duration in different species. In order to recover the hidden objects, animals must encode, maintain and correctly regain from their working memory the existence of the no longer visible object and its location from their working memory. Both donkeys and ponies performed the Detour task showing to grasp the fact that an object which is no longer perceivable still continues to exist and can be regained. They also were able to correctly retrieve the goal object after a delay of 10 s in the Working Memory tasks, showing that they had encoded, maintained and correclty retrieved from their working memory the spatial location of the hidden object as well as its existence. Nevertheless, when Standardbreds, raised in traditional stables, were tested in identical conditions to those describe for the ponies and donkeys, they could not succeed in the Detour tasks. The reason for such differences needs to be studied Even though it would be interesting to focus on handling differences, i.e., the ponies had been living in an environment rich in natural stimuli, while the Standardbreds had lived in a man-controlled environment since birth. It is also noteworthy that, like donkeys, the Esperia's pony have a reputation for being hard to handle. Several considerations could arise from our preliminary investigations, and we will have the pleasure to leave them open for discussion. |

Comprehension of human pointing gesture in domestic horses: Effect of training method | Type | Conference Article | ||

| Abstract | Horses have been considered to rely on human gesticular cues (McKinley and Sambrook 2000, Anim Cogn 3:13-22; and recently Maros et al. 2008, Anim Cogn 11:457-466), however large variability among individuals tested in two-ways object choice tasks was found. Part of the horses in those studies (40 and 26 %, respectively) even failed to pass adequately through the training session which preceded the testing phase and served to learn a horse to carry out a task. Therefore, we alternated the experimental design designed by McKinley and Sambrook (reduced number of testing trials to 10 per horse to keep its attention, applied just one, a dynamic-sustained pointing cue with touching the bucket, etc.), and tested an effect of training method, sex, age, and learning on proportion of correct choices. We hypothesised, that horses trained by “traditional” method (TTM) will get lower score than those experienced with “horsemanship-based” methods (HTM), being characterized by closer and more frequent human-horse contact and also extended exercising “from the ground” with frequent using of arms cues. Despite simplification of the methods, only about 60 % of tested horses passed through the training phase (i.e., learned to come to and upturn the bucket with hidden treat). Successful completion of training phase was reached regardless of age or sex of a horse, but by the training method; HTM horses ran better compared to TTM ones. No significant effect of age, sex, or learning (i.e., trial order within all 10), and training method as well was found on proportion of correct trials in the testing phase. Horses made a correct choice in more than 70% of trials. Individual scores ranged from 50 to 100 %. In conclusion, horses showed high level of comprehension of human pointing gesture, regardless of their sex or age. No effects of training method or learning process within a test suggest low impact of handling and learning on the level of comprehension at least of the most vivid human pointing gesture. Horses trained by methods based on “natural human-horse communication” did enhance cooperation with people. | ||||

| Keywords | social cognition, animal-human interaction, horses, attention | ||||
| Abstract | Horses fulfill many of the criteria for a species in which it would be adaptive to be capable of individual recognition: they are highly social, form strong and long lasting bonds, their affiliations are rarely kin based, they have a fission-fusion social structure and they possess inter and intra-group dominance hierarchies. We used a novel cross-modal, expectancy violation paradigm to provide the first systematic evidence that a non-human animal – the domestic horse- is capable of cross modal recognition. We believe this paradigm could provide an ideal way to study individual recognition across a wide range of species.
