| Abstract | Some behaviours remain a mystery and their determinants are still uncertain. Here we propose a critical interpretation of two puzzling behaviours, i.e. yawning and adult play, recorded in large samples of domestic horses kept in sub-optimal conditions (e.g. time-restricted feeding practices, social isolation). Yawning is involved in behavioural state changes, especially in quiet contexts of motor relaxation, but seems also to be triggered by stress and emotional contexts. Thus, we investigated specific correlates of yawning and stereotypic behaviours in two large samples of working horses (n1 = 87, n2 = 59). A clear co-occurrences of yawning and stereotypic behaviours appeared: stereotypic horses yawned more than the non-stereotypic horses (Fisher test, p < 0.02), yawning increased at the same time periods as stereotypic behaviours did (Wilcoxon tests, p < 0.05 to 0.001) and yawning frequency was even sometimes positively correlated with stereotypic behaviour frequencies (Spearman correlations, p < 0.005). Play, more typical of young stages in healthy individuals, occurs rarely at adult stages but then more often in captive/domestic animals (which can be challenging to welfare) than in animals living in natural conditions. Thus, we tested the hypothesis that adult play may reflect altered welfare states in horses, where, as in several species, play rarely occurs at adult stages in natural conditions. We observed the behaviour (in particular social play) of 29 adult riding school horses during occasional outings in a paddock and measured several stress indicators (health-related, behavioural and physiological) when these horses were in their home individual boxes. Results revealed that the number of horses and rates of adult play appeared very high compared to field report data and that most stress indicators measured differed between “players” and “non-players”, revealing that most “playful” animals were more prone to suffer from chronic stress contrarily to “non-playful” horses (Fisher, Chi-square, Mann-Whitney and Spearman correlation tests, p < 0.05 to 0.001). Altogether, these results show that yawning and adult play can both reflect altered welfare states in horses, highlighting that these puzzling behaviours should not be considered, as currently thought, as reliable indicators of good welfare states and / or expression of positive emotions. | ||||

| Abstract | Auf dem herbstlichen Zug in den Süden rasten bis zu 80 000 Kraniche im Hortobágy Nationalpark im Osten Ungarns. Das einst von Wildtieren besiedelte Gebiet ist heute eine Kulturlandschaft aus Feldern und Weiden, wo seltene Haustierrassen wie Zackelschaf, Graurind und Noniuspferde grasen, die von Hirten mit ihren Hunden gehütet werden. Die noch erhaltenen Steppengebiete zeichnen sich durch eine große Vielfalt in Flora und Fauna aus. Sie sollen möglichst wenig betreten werden, damit vor allem die bodenbrütenden Vögel, wie z.B. die seltene Großtrappe nicht gestört werden. Deshalb wurde die Kernzone – das Pentezug-Gebiet (2400 ha) – mit Przewalskipferden und „Auerochsen“ zur natürlichen Beweidung besetzt. Bereits in den ersten Jahren fiel es auf, dass das Rind deutlich schlechter an die kalte Jahreszeit angepasst ist als das Wildpferd. Deshalb wurden beide Arten besendert, um Körpertemperatur und Herzschlagfrequenz zu messen. Außerdem sollten Gras- und Kotanalysen Aufschluss über die Unterschiede in der Futterverwertbarkeit liefern. Der Film zeigt die chirurgische Arbeit im Feld und vermittelt einen Eindruck über die Funktion der Sender. Außerdem werden die neuen Bemühungen vorgestellt, aus dem Heckrind eine robuste Rinderrasse zu züchten, die dem Auerochsen noch ähnlicher sieht. Ein Ziel der Untersuchungen war es, die klimatischen Grenzen zu erkennen, in denen die „Auerochsen“ einen Winter ohne Zufütterung überleben können. Diese Rinderrasse wird verstärkt zur Beweidung in Naturschutzgebieten eingesetzt, ihren Bedürfnissen wird aber nicht immer Rechnung getragen. |

| Abstract | Initial equestrian training and especially first mounting of a rider are stressful challenges for young horses (1). Most young horses are raised in groups but, in association with equestrian training, they are commonly transferred to individual stabling in loose boxes. Although, in most stables, visual contact with horses in adjacent boxes is possible, separation from the herd might be an additional stressor. We have studied physiological stress parameters, in 3-year-old sport horse mares (n=8), transferred from a group stable with access to a paddock to individual boxes without paddock. Once stabled in the individual boxes, mares underwent a standard training for young horses. Horses had been accustomed to lunging and tolerating a rider on their back several weeks before the study. Mares were studied from 5 days before to 5 days after changing the stable. Cortisol concentration in saliva, locomotion activity (ALT pedometers), heart rate (HR) and HR variability (RMSSD: root mean square of successive beat-to-beat intervals) were determined. We hypothesized that the change of the stable increases cortisol release and is associated with changes in HR and RMSSD and reduced locomotion. Before mares were moved to individual boxes, cortisol concentration showed a pronounced diurnal rhythm with values around 0.6 ng/ ml in the morning and a continuous decrease throughout the day. When the mares were moved to individual boxes, cortisol concentration increased to 1.8±0.2 ng/ml and did not return to baseline values within 6 h (p<0.05 over time). On subsequent days, a diurnal rhythm was re-established but shifted to a higher level than before. Locomotion activity determined by ALT pedometers was increased for some minutes only after mares has been placed in individual boxes but was only slightly higher than during the time mares spent with the group in a paddock. On days 2-5 in individual boxes, locomotion activity was reduced compared to the group stable. HR increased and the HRV variable RMSSD decreased when mares were separated. In conclusion, separating horses during initial training from their group is an additional stressor, although the stress is less pronounced than induced by other social challenges, e.g. weaning of foals (2). When stabled in individual boxes, mares move less than when kept as a group. Horses kept in a group thus appear to exercise themselves freely, such an effect is absent when the animals are kept individually. | ||||

Picture recognition of con-specifics and facial expression in the horse (Equus caballus) | Type | Conference Article | ||

| Abstract | The management of the domestic horse often requires them to be kept in isolation from con-specifics. Installing a picture of a horse (generally head and neck view) with a view to providing surrogate companionship has been shown to reduce the negative impact of this isolation. This study aimed firstly to compare the spontaneous response of horses (N=10) to a 2-D image of a horse’s face (FP) with their response to a comparable abstract 2-D image (AP). Secondly, the spontaneous response of horses (N=20) to a 2-D image of a horse’s face with the ears forward (PFP positive) was compared with the response to a 2-D image of a horse’s face with the ears back (NFP negative). The posters were A1 sized and displayed in the horse’s own stable. In study 1, one poster was displayed for 5 minutes and the horse’s behaviour video-recorded. This was removed and the second poster was displayed for 5 minutes and the behaviour video-recorded. FP was displayed first for 5 of the horses and AP displayed first for the other 5. The video footage was observed and the behaviour of the horses and number of times they touched the poster recorded. For the purpose of identifying the area of the poster that was touched by the horse it was divided into 4 equal quarters (TL, TR, BL, BR). In FP the nose of the horse in the 2-D image was located in BL, eyes and ears in TL, chest and lower neck in BR and upper neck in TR. In AP each area contained similar but unique abstract patterns of comparable colour to FP. Differences in behaviour were found according to which poster was displayed. FP was touched significantly more than AP (p=0.001) and was looked at more often (p=0.008). With FP the horses spent significantly longer with their ears forward (p=0.008) and licking and chewing (p=0.016). When the number of touches per poster area was compared (FP and AP) a significant difference was found in the number of times that BL (nose) and BR (chest/lower neck) were touched (p=0.011). Both areas were touched more frequently on FP, with BL being touched the most. In study 2 the same experimental protocol was used to compare responses to positive (PFP) or negative (NFP) 2-D images of a horse’s face (same horse in both PFP and NFP). Again, differences in behaviour were found in response to the two posters. PFP was touched significantly more than NFP (p=0.002) and on both posters the area BL (nose) was touched more frequently than the other areas (PFP: p=0.02, NFP: p=0.01). More ears back behaviour (p<0.001) and more ear locked on behaviour (p=0.008) was shown with NFP. The results of these studies indicate that horses can recognize 2-D images as con-specifics as well as responding to differences in facial expression. There is now the potential for further investigation into the importance of other visual cues in recognition and social interaction as well as the application of findings to enhance equine welfare. | ||||

| Abstract | Introduction: The feral horse population of Australia is the largest in the world and, in average seasons, increases at a rate of approximately 20% per annum. Recent record rainfall in much of semi-arid Central Australia has led to a population increase in excess of normal rates and this project aimed to document the increase. Uncontrolled feral horse numbers have habitat degradation and horse welfare implications and were the reasons for performing the study. Materials and Methods: The study area was an unmanaged 4,000km2 semi-arid area in Central Australia (Lat 24.50, Long 132.10). The population of feral horses within the study area is estimated to be in excess of 10,000. During an 8 week period at the end of the winter season of 2011, horses were identified by ground searches, movement sensored cameras and from hides positioned at key water holes. The area surveyed represented only a small percentage of the overall habitat. Horses were identified by descriptive features and markings. Where possible, sex and age category were documented. Population growth rate was estimated from the observed sample and was expressed as the number of foals born in the current year, divided by the number of horses older than one year. Results: A total of 1,486 horses were identified and categorised, of which 335 were foals born within the current foaling season. Only 129 juveniles, presumably born in the preceding year, were identified. Of the adult horses, 54% were male and 46% were female. Seventy-four percent of mares (n=452) had a foal at foot and the population growth rate was 29%. Conclusion: With a sustained population growth rate of 29%, this population of feral horses will more than double within 3 years. The high rate of increase is concerning because it will negatively impact on the native fauna and flora and fragile semi-arid ecosystems of Central Australia. In addition the feral horses of the study area have experienced an unusual period of high rainfall and plentiful grazing but a return to normal drought conditions is imminent. Starvation, thirst and death from diminished resources will then be a serious welfare concern for horses. KW - | ||||

Prevalence of stereotypies amongst Thoroughbred race horses (Equus caballus) in Greece | Type | Conference Article | ||

| Keywords | Thoroughbred, race horse, stereotypy, Greece | ||||
| Abstract | Thoroughbred horses are keen to develop stereotypies in higher rates compared to other breeds. In Greece, race horses are exclusively thoroughbreds, which are intensively kept under strict environments. Our study, the first of its kind in Greece, explores the prevalence of stereotypic behaviour in these horses and its interrelation to intrinsic and management factors. For these purposes, we recorded intrinsic (age, gender, indoors and outdoors temperament, playfulness, etc.) and management parameters (time spent out, number of horses per groom, etc.) in association with established stereotypic behaviours (box walking, weaving, head nodding, wind sucking, bed eating) in 209 horses in the Markopoulo Race Track, Attica, Greece. Our analysis showed an overall prevalence of 46.6 %, which is way too high compared to those reported for other race horses worldwide. Furthermore, box walking was strongly associated with indoors temperament (p=0.012), playfulness (p=0.03), and horses per groom (p<0.001). Bed eating with gender (p=0.009), outdoors temperament (p=0.018) and playfulness (p=0.004), while head nodding with indoors and outdoors temperament (p=0.001 and p=0.002, respectively). These results corroborate with previous investigations in other race horses, and indicate the importance of intrinsic factors in developing stereotypies in Thoroughbreds. | ||||

Project on paternal effects to the cognitive and social development of the offspring on feral horses (Equus caballus) | Type | Conference Article | ||

| Abstract | Horses provide an interesting animal model to test short- and long-term effects of the paternal influence on the offspring under natural conditions. As a highly social animal, horse naturally is living in long-term harem groups building strong familiar bonds. Arguing that the environment of a juvenile is highly important for the development of cognitive and social functions as well as for the emotional competence, a future study on domestic horses wants to highlight the paternal influence on the offspring as well as special effects of the stallion during the first two years of the foals´ life. Nowadays, in most husbandry systems it is still common to keep the stallions separated, raising the offspring in an intact harem group is very rare. The aim of this study is to describe the role of the stallion in the early development of the foal in an extensive pasture management system living in natural harem groups. Results are going to be compared to findings of studies on groups without the male present in the rearing phase. A precise behavioural analysis is planned; direct behavioural observations are going to be supported by long-term and continuously activity measures by special telemetry collar systems. Additional physiological measures should give evidence of the investment of the stallion. The young horses will be confronted with different tests of cognitive and social abilities (exploration behaviour, fear behaviour, play behaviour). The results of this study will contribute to fundamental research in the behaviour of the horse and might display an important step to animal welfare in modern horse husbandry. It will be possible to set a time-frame in which the male does have positive influence on the offspring and therefore should be kept with the family. A detailed knowledge of the influence of the male to cognitive and social abilities could as well be applicable in the training of horses and therefore be of great importance in equestrian sports. | ||||

| Abstract | It is a common practice that the domestic horse mare is removed from her home environment and transported elsewhere for mating. After conceiving she is returned back into her home environment and social group, containing often familiar stallions and geldings. If we presume that the behavioural adaptation for infanticide relevant for wild, or free-ranging horses has not be lost in domestication (and it is clear that it remains at least within feral populations), then we may expect that, unless prevented by fencing or other management measures, the dominant males in the home social group may subsequently attempt infanticide. Foetal loss is a common phenomenon in domestic horses, being usually substantially higher than that in other domestic ungulates reaching up to 40%. One adaptive response to infanticide risk in polygynous populations is the Bruce effect. Pregnant females terminate their pregnancies when exposed to a dominant strange male. Our previous studies on plain zebra suggested the possibility of the Bruce effect also in equids. In this study we therefore tested the presumption that the Bruce effect could explain foetal loss in domestic horses. Based on reproduction records from horse breeders, we have recently published that bringing a pregnant mare which had been mated away from home into a vicinity of a familiar male who was not the father of her foetus increased probability of pregnancy disruption (Behav Ecol Sociobiol DOI: 10.1007/s00265-011-1166-6). These mares aborted in 31% of cases, while none of those mated within the home stable aborted. Repeated sexual activity either by a stallion or dominant gelding from the normal home group was observed shortly after the mare came from away-mating. Pregnant mares isolated from home males by a fence were even seen soliciting them over the fence. Therefore, there is probably some other mechanism than the Bruce effect leading to pregnancy block in the mare. We speculate that, once returned to the home “herd”, and introduced to familiar males, mares were more likely to terminate their pregnancy to save energy and avoid likely future infanticidal loss of their progeny by dominant male(s) of the home social group. Additional data has now showed that if a mare was mated away from home and was brought into an environment containing mares only, she was less likely to abort than a mare returning to an environment containing familiar male or males. This further supports our above hypothesis. Supported by AWIN, EU FP7 project No. 266213. | ||||

| Abstract | The University of Applied Science and Technology (UAST) was founded in 1992, with the objective to promote the technical as well as the scientific knowledge of the job holders, mainly those who are working as low-skilled or semi-skilled laborers in different sectors of the economy. With a growing importance of the equestrian sports and horse husbandry, there is an increasing need for well-trained professionals in the equine sector. The need for specific equine university programs has been questioned occasionally; however, neither university programs in the equine veterinary medicine (focusing on diseased horses) nor animal science (focusing on food-producing farm animals) meet the broad requirements of today's equine industry. So far four programs in the equine sector has been approved in the UAST; an associate diploma program in the horse husbandry, an associate diploma program in the equine coaching, a bachelor program (2 + 2 years course) in the horse husbandry and a post graduate program in the horse physiotherapy and massage at master level (Msc. program). The main specifications of the applied science programs are ; the abilities of the applicants and their attainable jobs are pre-planned before starting the program ( each applicant will be aware of what abilities he/she would earn and what jobs he/she would attain after graduating from such scientific and applied programs). The first academic program in the equine science and management in Iran was established in 1998 by the UAST. The 2 year associate diploma program (74 credit points) includes sciences, anatomy, physiology, genetics, nutrition, horse behavior, economics, marketing, management, horse disease and disorders, basics of shoeing and basics of ridding. In 2004 when more than 200 students were graduated in this program a two years course (a 2 + 2 bachelor program) was established. In this program almost all subject taught at the previous program were taught, but at advance level. Courses are provided by the partner higher education centers affiliated to the UAST and approved by the Iranian Equestrian Federation and by the lecturers from practice and ridding clubs. Lectures and seminars are complemented by a scientific thesis and placements in the equine industry. Out of 400-500 applicants each year, 60 students are selected (to study in two higher education centers) on the basis of their previous activities, a written test and interviews. The majority of the students enter the program with previous experience of working with the horses and about 35% of the students enter the program directly after leaving secondary school. More than 50% of the graduates enter into the subsequent BSc. program in horse husbandry. Other 50% graduates (almost those with previous experience) return to the horse husbandry business and works as stud managers or management assistants in ridding clubs. In conclusion, graduates of the University of Applied Science and Technology programs follow a wide-range of professional and academic activities within the equine industry as well as equine medicine (graduates of the UAST's master program in the horse physiotherapy). This spectrum is by far more extensive than the sector covered by merely academic training. With practical experience obtained on the job, adequately qualified graduates will more and more obtain leading positions. KW - | ||||

| Abstract | The use of molecular techniques has increased our understanding of biological systems; in particular how genes and proteins operate within a cell or organ in response to various stimuli. These techniques can be used to study modes of action or mechanisms in disease states, or in response to applied management or nutritional changes. While applied and basic research are often conducted independent of one another, the real advantages to the equine industry will come from the use of molecular techniques to address applied challenges and/or opportunities within the industry. Therefore, the overall goal of our research has been to use basic and molecular tools to investigate modes of action resulting from changes in nutrition or management. We investigated active nutrient transport capacities of the small and large intestine, the effects of feed withdrawal on intestinal transporter gene expression and function, as well as other measurements pertaining to gut health (gut barrier function and gastrointestinal morphology). This novel and thorough approach to characterize sectional differences (fore- and hind- gut) of nutrient absorption has resulted in quantitative measures of active transport capacity for glucose, phosphorus, glutamine, lysine, and di-peptides in the horse. This research demonstrates that by-products of fermentation in the cecum such as microbial proteins and hydrolyzed phytate phosphorus, can be absorbed in the colon. Previously unidentified in the hindgut of the horse, we reported the expression of the di-and tri-peptide transporter, PepT1, as well as the neutral amino acid transporter, ASCT2, and transport of their substrates. We observed that nutrient transporters for glucose (SGLT1), glutamine (ASCT2) and for di-peptides (PepT1) can be regulated by diet, implying biological relevance to feeding management strategies. Feed withdrawal in horses pre- or post-surgery, prior to or during horse shows, during transport, or for other management reason is common. It is therefore important to understand how the removals of nutrients impacts gut health and/or disease susceptibility. The use of molecular techniques has provided a basis for the roles of certain core nutrients during times of feed withdrawal. For example, nutrients such as glutamine play a major role in proliferation and repair in the gut, serve as a major energy substrate, and may provide a means of assessing nutritional stress in the gut. Recent data concludes that following a feed withdrawal, the need for glutamine increases up to 116% in the proximal jejunum, and the gene expression of its transporter (ASCT2) increases by 78%. Additional studies utilizing molecular techniques to address nutritional challenges in the horse include how hormone loss due to ovariectomization impacts the homeostatic regulation of calcium and phosphorus in the horse. To improve nutrition and feeding management practices in horses, knowledge regarding how and where nutrients are absorbed, utilized and regulated under varying physiologic stressors (disease, exercise, reproductive status, etc.) is needed. The integration of applied and basic research facilitates a better and more complete understanding of mechanisms underlying common health and nutritional challenges facing the equine industry. | ||||
