Abstract  |
Veterinary treatments are often aversive or painful, resulting in stress, avoidance, or aggressive behaviour. This preliminary study investigated which behaviours horses and humans display during veterinary examinations or treatments and if specific behaviours are shown more often during particular situations . Moreover, possible links between human and equine behaviour were investigated. Behaviours of horses, veterinarians, and assisting people were recorded at 5 clinics during 49 routine treatments that were divided into 111 situations (assigned to 7 categories: giving injections, waiting, leading horses, inspections with light body contact, invasive inspections, leg inspections, spraying/shaving). Behaviours of humans present during a situation were summarised. Behaviours (frequencies/minute) were analysed by Kruskal-Wallis tests and Spearman rank correlations. Horses showed insecurity (stopping, baulking, defecation) with different frequencies in the different categories (Chi2=23.38, df=6, P=0.001), e.g., often during leading. In humans, activating behaviour (e.g., arm waving, whistling, tongue clicking) was displayed with different frequencies (Chi2=20.42, df=6, P=0.002), e.g., frequently during leading. Restlessness in horses (e.g., stepping, head movements) tended to occur with different frequencies (Chi2=12.37, df=6, P=0.054), e.g., often during invasive inspections. Humans applied restraining techniques considered to be painful (e.g., ear twisting) with different frequencies (Chi2=26.20, df=6, P<0.001), e.g., mostly during invasive inspections. Restlessness in horses correlated with negative human interactions (e.g., hitting, talking impatiently, shouting: rs=0.28, P=0.002, n=111) and neutral human interactions (e.g., slight hits, talking dominantly: rs=0.45, P<0.001, n=111) as well as with the use of painful restraint techniques (rs=0.46, P<0.001, n=111). Moreover, avoidance behaviour of the horses (turning and stepping away) correlated with negative human interactions (rs=0.30, P=0.002, n=111). Thus, humans and horses showed certain behaviours in different situations with differing frequencies. Moreover, links between human and animal behaviour were found. Future studies should analyse causal connections, i.e., if the observed animal behaviour is the result of/or the reason for human interactions by sequence analysis. KW - |

Abstract |
We are introducing a new research and experience center located near the stripmine of Schöningen in western Germany, one of the most important archaeological sites in the world, which is scheduled to open its doors in 2013. The 1995 discovery of wooden hunting spears (Thieme 1997) in conjunction with the remains of hunted and butchered horses (Equus mosbachensis) contributed significantly to change the scientific view of early European Hominids being “marginal scavengers” (Binford 1981, Gamble 1987) to skilled hunters. The remains of at least 19 horses were unearthed along a former lakeshore. Initial publications demonstrate early hominid butchery systematics designed to achieve a thorough acquisition of horse products (Voormolen 2008). In order to get a better understanding of the possible hunting scenario (Thieme 2007) knowledge of wild horse behaviour is of primary interest. The exhibit section of the new center is developed to present an experience oriented concept. Access to artefacts, such as the over 300.000 year old spears, is correlated with exhibits concerning Pleistocene horse morphology, group structure and behaviour of modern day wild horses in order to draw a vivid image of the past |

Abstract |
We observed the activity and movements of Konik horses (Equus caballus) in order to determine the initiators of movements and the individuals taking the lead in movements of the main groups. We conducted our observations between March-June 2010 along the shores of the Rhine river, in the Blauwe Kamer reserve, in the Netherlands. The horses were introduced to the reserve alongside with cattle to prevent the growth of the forest and maintain the grass habitat. We videotaped all observations on two digital video cameras, one providing the general view of the group and the other scanning and focusing on the individuals, to aid with identification. Horses were recognized based on individual profiles that were created for each one, consisting of photos of both sides and notes of the main characters, such as orientation and coloration of the mane, prominent scars and markings, etc. Twenty three horses (not counting foals) were organized in two harem groups with 11 individuals (two of which were dominant stallions) in the large group and six individuals (one of which was a stallion) in the second group. These two main groups were always within sight of each other, and two bachelor males moved usually in their vicinity. An additional group of three young bachelor males roamed elsewhere in the reserve. We divided the movements of the horses to local movements while grazing and to long-distance movements, in which the horses moved to a different grazing location, to a pond of water, resting area or groups of trees that were used by the horses for scratching themselves. During the local movements, any two of the three oldest females in the large harem group were enough to cause the whole group to follow them and gradually change position within the pasture. The smaller harem always followed the large harem’s movements. The long-distance movements of the large harem were sometimes initiated by one of the harem stallions that herded their group and at other times – by the oldest females. Soon after the movement was clearly initiated, the dominant stallions positioned themselves in the back of the group or in the center and had no influence on the direction of move that was only determined by the leading females. In the long-distance movements too, the small harem followed the large harem group, and the two bachelor males usually followed behind them. Social interactions included aggressive interactions between the two dominant males within the large harem or between dominant stallions and the two bachelor males accompanying the two harems. In addition, dominant males courting or attempting to mate with mares sometimes caused a turmoil that eventually initiated movement of the harems. KW - |

Abstract |
We presented small groups of chimpanzees with two collective action situations, in which action was necessary for reward but there was a disincentive for individuals to act owing to the possibility of free-riding on the efforts of others. We found that in simpler scenarios (experiment 1) in which group size was small, there was a positive relationship between rank and action with more dominant individuals volunteering to act more often, particularly when the reward was less dispersed. Social tolerance also seemed to mediate action whereby higher tolerance levels within a group resulted in individuals of lower ranks sometimes acting and appropriating more of the reward. In more complex scenarios, when group size was larger and cooperation was necessary (experiment 2), overcoming the problem was more challenging. There was highly significant variability in the action rates of different individuals as well as between dyads, suggesting success was more greatly influenced by the individual personalities and personal relationships present in the group. |

Abstract |
We tested untrained horses (foals and breeding mares) in 3 different breeding centres. Horses were kept in a pasture during daytime in bigger groups (median 12, min: 6, max 35 / pasture) according to age, gender and breed (hungarian halfbred, hucul, arabian and thoroughbred). To measure their reactions to an unfamiliar person we conducted an active and a passive human test. In the active human test the test person (TP) approached a focal animal in the group from a predetermined direction: from their front, from their side (left or right) or from the rear. As TP reached the horse (of app. 0.5 m distance), she tried to pet the animal’s head. The TP always chose and approached a standing or a grazing horse (ie. those that were not walking, galloping, playing etc.). The horse’s reaction to the approaching human was scored 1-5. Score 1: the horse moved away and the TP could not even approach it within 0.5 m; Score 2: the horse made max. 2 steps away, but could be reached and petted; Score 3 and Score 4: the horse stood in its place but showed different signs of discomfort (head turn – Score 3; backing ears, tail slash – Score 4); Score 5: the horse stood and did not show any sign of discomfort or actively approached the TP. There was no significant difference in the horses’ reaction between approaching from their left or right side. Approaching from their front or from their side (left or right) did not differ significantly either. However, the odds of walking away from the TP (score 1 or 2) was 2.7 (Fisher-test, p=0.039) and 3.3 (p=0.012) times higher when TP approached from the rear compared to approaching from their front or from their side (left or right), respectively. In the passive human test the TP stood immobile for 4 minutes in 5 or 10 m far from the horses during their active (grazing) or inactive (standing idle during noon) period. Horses approached TP significantly sooner (general linear model, p=0.017) when she stood 5m distance (38 ±63 s) compared to 10m (97 ±52 s). The arrival of a second horse after the first horse approached the TP showed significant high correlation with the latency of the first horse arrival (Pearson correlation, r=0.96, p<0.001). The horses were less keen (p=0.008) to approach the human when they were tested in an inactive period (177 ±110 s) compare to active period (38 ±63 s). |

Abstract |
While detailed information exists on the cardiovascular response of horses to racing or endurance, much less is known about cardiovascular function of the rider in equestrian sports. Combined analysis of the horse-rider-team has not been investigated so far. In this study, we have analyzed changes in heart rate and heart variability (HRV) variables SDRR (standard deviation of beat-to-beat interval) and RMSSD (root mean square of successive beat-to-beat intervals) both in well-trained horses (n=9) and their highly experienced riders (n=7) during the airs above the ground (sauteurs en liberté of the Cadre noir de Saumur) at a public performance and at an identical, but non-public training session, both lasting for exactly 7 min. Heart rate in the horses and riders increased during the airs above the ground, both in training and in the public performance (p<0.001 over time). In the horses, this increase did not differ between training and public performance (training: from 35±6 in the stable to 97±17 beats/min during riding, performance: from 43±13 to 103±13 beats/min, respectively). In contrast, in the riders, the increase in heart rate was significantly more pronounced (p<0.01) during the public performance (basal value 91±10, maximum 150±15 beats/min) than during training (basal value 94±10, maximum 118±12 beats/min). With regard to HRV in horses, overall SDRR did not change significantly over time and did not differ significantly between training and performance. RMSSD decreased during both training and performance to the same extent, indicating a decrease in parasympathetic (vagal) tone. In the riders, both HRV variables decreased significantly during riding (p<0.001) and for SDRR the decrease was more pronounced (p<0.05) during an equestrian performance compared to a training session. During the performance SDRR decreased from a basal value of 5.0±1.5 to a minimum of 3.2±0.6 msec while respective values for the training session were 5.3±1.1 and 2.3±1.1 msec. Both a public performance and an identical training session of the airs above the ground in the ridden horse caused an increase in heart rate and a decrease in HRV variables. While increases in heart rate are mainly caused by physical activity, decreases in HRV also indicate a stress response. The cardiovascular response in the horses did not differ between a training session and a public performance but clear differences could be demonstrated in the riders. During a public performance, the increase in heart rate and decrease in SDRR were more pronounced than during a similar training session. In conclusion, the presence of an audience thus causes more pronounced sympathoadrenal activity in experienced riders than the same equestrian tasks ridden without spectators present. In contrast, the presence of an audience was without effect on sympathoadrenal activity in experienced horses. KW - |

Abstract |
While writings from the Hittite Kikkuli and the Greek hippiatrica concerned stamina training and mainly veterinary aspects, the first explicit writings left about schooling are from the hand of Xenophon. He showed already a plight to understand the horse’s behaviour and apply an animal-friendly schooling. What happened in Roman times and early middle ages is unclear through a lack of documents. Literature increased in late middle ages (a few Iberic authors and the Italian Rusius) but remained scarce. One presumes knights were brutal because of the strength of bits and spurs, but iconography shows also horses ridden without coercion. Linear progress in schooling cannot be found before the transition between the renaissance and baroque periods. Writings from renaissance masters such as Grisone, Fiaschi, Pignatelli and de la Broue, show a generally violent way of schooling (excepted Conte and Pavari) strangely contrasting with appeals for kindness. One then observes from the 17th century authors to the 18th century baroque masters a gradual improvement concerning important aspects: evolving 1/ from anthropomorphism to understanding horse behaviour, and 2/ from coercion to obtaining gradually suppleness and applying the laws of physics concerning weight distribution. Many baroque and early 19th century masters had understood intuitively conditioning laws discovered scientifically in the 20th century by the Pavlovians and behaviourists. The essence of schooling was settled in the baroque period. It subsided unfortunately in the 19th (with better survival in Germany, Austria and Iberic countries) because of a/ more interest for racing and hunting, b/ the French revolution that closed academies and c/ mass army training. Pressure of competition in the 20th nearly eradicated academic tradition. In the second part we translate some fundamental riding principles into scientific terminology. “Independence of aids” is based on discrimination of stimuli and overshadowing. “Discretion of aids” on generalization and second-order conditioning. “Descente de mains et de jambes” on avoidance of habituation, of confusion, and of the impossibility to apply negative reward. “Legs without hands, hands without legs” on avoidance of experimental neurosis due to contradictory stimuli. Time permitting, processes such as positive social modelling and occasion setting will be explained. The above mentioned principles are rarely applied nowadays. The FEI holds a large responsibility in the acceptance, even institutionalizing, of a probably animal-unfriendly riding. It is also shameful that some schools, that for years, or even centuries, were the guardians of old principles, are relinquishing them under commercial pressure. All too often, modern riding is obviously animal-unfriendly for the intuitive rider. Scientists however seek facts. Frequency of conflict behaviours is an indicator at ethological level. However, some horses could be in learned helplessness. There is no litmus test for that (except complicated avoidance learning procedures). There is a need for physiological stress parameters according to breed, age, sex. Horses schooled according to different philosophies are often from different breeds making matched-pairs studies difficult. The important role of pre- and postnatal experience complicates precise scientific evaluation in everyday equine practice. One cannot standardize ontogeny in horses as in laboratory animals.

Abstract |
Zusammenfassung
Gegenstand und Ziel Seit 2000 siedelt sich der Wolf in Deutschland wieder an. Mit steigenden Wolfszahlen nehmen die durch Wölfe verursachten Nutztierschäden zu, wobei auch Pferde betroffen sind. Ziel der Studie war es, einen Überblick zu dieser Problematik sowie Lösungsansätze zu geben.
Material und Methoden Anhand einer Literaturrecherche wurden Daten zur Wolfspopulation in Deutschland, wolfsbedingten Schäden sowie Möglichkeiten und Grenzen des Herdenschutzes beim Pferd eruiert. Eine Online-Befragung von Pferdehaltern/-besitzern diente dazu, die tatsächliche und/oder gefühlte Bedrohung durch Wölfe und die daraus resultierenden Auswirkungen auf die Pferdehaltung zu ermitteln.
Ergebnisse Die Literaturrecherche zeigte ein kontinuierliches Anwachsen der Wolfspopulation in den letzten Jahren und insbesondere seit 2016 einen deutlichen Anstieg wolfsverursachter Nutztierschäden, wobei Pferde selten betroffen waren. Bei der Online-Befragung stammte die Hälfte der 574 ausgewerteten Fragebögen aus Brandenburg und Niedersachsen. Den größten Einfluss auf die Gefährdungsbeurteilung eigener Pferde durch die wachsende Wolfspopulation hatte das Wissen der Pferdehalter über Wolfsangriffe im eigenen Landkreis, wobei insbesondere die Aspekte einer Haltung von Jungpferden und Weidegang für die Pferde eine Rolle spielten. 64 % der Befragten gaben an, ihre Pferdehaltung trotz der zunehmenden Wolfspopulation nicht geändert zu haben. Nur 8 von 576 Pferdehaltern gaben amtlich bestätigte Wolfsübergriffe an und 30 hatten einen vermuteten Wolfsschaden amtlichen Stellen nicht gemeldet. Mehr als die Hälfte der Befragten, die Kontakt zu einem Wolfsberater hatten, bezeichneten die Zusammenarbeit als nicht bis wenig zielführend.
Schlussfolgerung und klinische Relevanz Die Zahl amtlich bestätigter Wolfsangriffe auf Pferde ist gering. Durch einen grundsätzlich durchgeführten Gentest bei entsprechendem Verdacht ließen sich diese Zahlen objektivieren. Trotz des Bewusstseins einer zunehmenden Gefährdung von Pferden durch Wölfe unternehmen Pferdehalter überwiegend keine prophylaktischen Schutzmaßnahmen. Die Kommunikation zwischen den für das Wolfsmonitoring zuständigen Behörden und den Pferdehaltern erscheint verbesserungswürdig.
Abstract
Objective Since 2000 the wolf population is reestablishing itself in Germany. In consequence to increasing numbers, livestock damage caused by wolves is on the rise, with horses likewise being affected. The aim of the study was to provide an overview of this challenge and its possible solutions.
Material and methods Based on a literature research, data on the wolf population in Germany, wolf-related damage as well as possibilities and limitations of herd protection for horses were evaluated. An online survey addressed to horse owners/keepers served to determine the actual and/or perceived threat posed by wolves and the resulting effects on horse husbandry.
Results The literature search showed a continuous increase of the wolf population in recent years as well as a significant increase of wolf-caused livestock damage in general especially since 2016; although horses were rarely affected. Half of the 574 evaluated questionnaires were from Brandenburg and Lower Saxony. The greatest influence on the individual risk assessment concerning their own horses by the growing wolf population was the horse owners� knowledge of wolf attacks in their own county. Especially the aspects of keeping young horses as well as pasture keeping played a significant role. 64 % of respondents indicated that they had not changed their horse management practices despite the increasing wolf population. Only 8 of 576 horse owners had reported officially confirmed wolf attacks and 30 respondents had not reported a suspected wolf damage to official agencies. More than half of the respondents who had contact with a wolf advisor described the cooperation as either not or only slightly purposeful.
Conclusion and clinical relevance The number of officially confirmed wolf attacks on horses is low. These numbers could be objectified by a routinely performed genetic test in case of corresponding suspicion. Despite the awareness of an increasing danger of horses by wolves, horse owners mostly do not undertake prophylactic protection measures. The communication between responsible authorities for wolf monitoring and horse owners seems to be in need of improvement. |

Abstract |
Parascaris equorum (ascarid; roundworm) is a common nematode parasite which occurs in the small intestine of immature horses world-wide. Adult female ascarids lay eggs in the small intestine, and these eggs pass into the environment within the feces of the host. P. equorum is one of the rare nematodes which induce absolute acquired immunity. Most horses become immune during the first year of life, so patent ascarid infections are rarely diagnosed in horses over two years of age. The aim of this study was to determine the prevalence of infection with parascaris equorum in Tehran’s riding clubs. The prevalence and rate of infection was determined based on the coproscopic examination. Fecal samples were tested for the presence of parascaris using suspend method. In this investigation, 442 fecal samples of horses from North-East of Tehran’s riding clubs examined. From the viewpoint of parascaris roundworms, fecal samples were obtained from each box separately and send in containers with plastic lid. The samples were then transferred to the parasitology lab for further examination. The infection was recognized based on the observation of parascaris eggs in coproscopic examination. The infection rate in the foal in this study was zero percent. Another interesting result was increasing the infection rate in horses of 10 years or even older and gelding. Out of 442 samples, the infection rate in the samples taken in summer, was 3.16%, and in the fall, winter and spring it was 2.4%, 10% and 3.16% respectively. The infection rates in relation to the age, sex, excursion condition, seasons and deworming programs was studied too. The results showed that the local and the imported horses should be monitored parasitologically, because endoparasites may create a major epizootiolocall problem when these animals are kept in an organic raising system. Deworming program is to be continued with proper methodology, dose and throughout the productive age of the horses. |
