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 |
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 |
The present study aims to investigate whether the presence of unrelated adult horses at weaning would reduce the social stress of weaning and the emergence of undesirable behaviours. We tested this hypothesis in 32 domestic foals by comparing short and medium term behavioural and physiological responses to weaning in foals maintained in homogeneous groups of peers (PW) to those of foals grouped with both peers and unrelated adults (AW). In total, three trials were conducted, which each trial consisting of one AW group and one PW group. In all foals, weaning was followed by increased vocalization, increased locomotion and increased salivary cortisol concentration. However, signs of stress were less pronounced and shorter in duration in weanlings housed with unrelated adults (e.g. whinnies: p < 0.05; salivary cortisol: p < 0.05). Only foals without adults exhibited increased aggressiveness towards peers (p < 0.05) and abnormal behaviours (p < 0.05) such as excessive wood-chewing and redirected sucking towards peers. In conclusion, introducing adults to minimize weaning stress in foals and later on aggressiveness and abnormal behaviours appears as the most promising approach to date. |

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. |

Abstract |
For a longer time, I occupy myself in my profession as a veterinarian, with the requirements and strains of horses (Equus caballus) used to contribute human health. For the first time complex and interdisciplinary scientific investigations are made to draw conclusions from determined requirements and strains of so-called therapy horses in regard to an adequate selection and training as well as compensation of physical and psychic strains and rectification of these horses. Focusing the physical and psychic resources of horses as well, it becomes obvious, that a horse which received conventional training, compensation and rectification is neither adequately prepared for its task as a therapy horse, nor adequately escorted through its employment. Therefore it is time now for hippologists and veterinarians to promote a justifiable use of horses for therapy purposes by suitable means having in mind not only the efficiency of the intervention, but also the safety of clients, therapists and horses as well as our responsibility towards the horse and animal welfare in general. For a concept profitable for all participants, different, each other complementing modules are worked out. Based on an interdisciplinary exchange of know-how and interdisciplinary cooperation, the decisive elements of a comprehensive, targeted, requirement-oriented and horse-friendly training, compensation of the horse’s strains and rectification are outlined. |

Abstract |
Als Tierärztin beschäftige ich mich seit geraumer Zeit mit den Anforderungen und Belastungsmomenten von Therapiepferden. Mein Ziel ist es, geeignete Methoden für die Auswahl, Ausbildung, Ausgleichs- und Korrekturarbeit dieser Pferde zu entwickeln.
Umfangreiche Recherchen haben ergeben, dass ein Pferd unter Berücksichtigung seiner physischen und psychischen Fähigkeiten durch die derzeit verbreitete Ausbildung, Ausgleichs- und Korrekturarbeit nur unzureichend auf die Aufgaben eines Therapiepferdes vorbereitet bzw. während seinesEinsatzes begleitet wird.
Aber genau hier liegt der Schlüssel für die Sicherheit von Klient, Therapeut und Pferd und den Erfolg der Therapie- und Fördermaßnahme. Darüber hinaus ist es auch im Sinne der Verantwortung für das Pferd und des Tierschutzes an der Zeit, durch geeignete Maßnahmen die verantwortbare Nutzung des Pferdes als Therapiepferd zu unterstützten.
Auf der Basis von interdisziplinärem Wissenstransfer und interinterdisziplinärer Kooperation werden die entscheidenden Elemente einer nachvollziehbaren, zielorientierten, bedarfs- und pferdegerechten Ausbildung, Ausgleichs- und Korrekturarbeit von Therapiepferden kurz skizziert. |

Abstract |
Temperament is an important factor when working with horses. Behavioral tests have been developed to measure certain dimensions in horses. Relations between temperament and ability to riding activity have been highlighted (Lansade 2008a). The aims of this study were 1) to evaluate the effect of age on temperament, 2) to verify that temperament are related to breeds 3) to check if the ease to be ridden is in relation with temperament, on a first set of data. Five dimensions of temperament have been measured in 98 field stallions (Table 1). They were tested as described by Lansade (2008 a,b): fearfulness/curiosity (tests: crossing a novel aera, suddenly opening an umbrella, novel object), gregariousness (test: isolation), locomotor activity (during the other tests), reactivity/curiosity to a non familiar human (tests: passive and active human), tactile (Von Frey filament) and auditory sensitivities. Table 1: Number of stallions according to breed (or group of breeds) and age. Breeds or groups of breeds Young (<13 years) Old (>=13 <20 years) Merens 1 15 10 Leasure horse breeds 2 13 10 Jumping pony breeds 3 / 20 Jumping horse breeds4 9 10 Arabians / 11 Total 37 61 (1) Merens : french mountain horse breed (2) Appaloosa, Barbe, Lusitanian, Polish, Paint (3) French Saddle Pony, Connemara, New Forest, Welsh (4) French Saddle Horse, Anglo-Arab, KWPN, Foreign breeds Effect of age. Due to imbalanced data, only stallions from 3 breed groups were compared (29 young ones selected at random and 30 old ones). Young stallions presented a higher emotivity (more elevated distance/intensity of the flight after umbrella opening (P=0.001)) and curiosity (more sniffings/nibblings the passive human (P=0.04) and the novel object (P<0.0001)) compared to old ones. Relation with breed groups. In young stallions, differences were noted : in the number of trots during social isolation (P=0.001) and in the tactile sensitivity (P=0.005). Merens had smaller values than Jumping horses for these 2 variables. In older stallions, differences were also noted: in the number of sniffings/nibblings the novel object (P=0.04), in the manner to cross the novel aera (P=0.03), in the distance and intensity of the flight after umbrella opening (P=0.04), in the number of trots during isolation (P=0.02) and in the tactile sensitivity (P=0.03). Merens had lower reactivity compared: 1) to Arabians (for novel aera) and 2) compared to Jumping ponies and Jumping horses (for isolation and tactile sensitivity). Minimal level of rider. Stallions of all ages and breeds were divided into 3 groups according to the level of riders able to ride them safely, according to a questionnaire: beginners, intermediate level and pre-national competition level. Stallions adapted to beginners showed lower values in the number of trots during isolation (P=0.02) and in the tactile sensitivity (P=0.03) than stallions rode by pre-competition level riders. Conclusion : The intensity of fear reactions to suddenness decreased with age. Differences between breeds and eases of use have been related to temperament measurements. |

Abstract |
Among mammals, lactation is the most energy demanding part of parental care and so parentoffspring conflict should arise over milk provided by the mother. Mother and offspring should disagree over the length and amount of the milk provision. We focused on effect of pregnancy on suckling behaviour variables as indicators of mother-offspring conflict in domestic horses. We presumed shorter suckling bouts and higher rates of rejected and/or terminated suckling in pregnant mares compared to non-pregnant ones. Increasing conflict over amount of maternal investment between mother and her young are to be expected because of her parallel investment into a nursed foal and a foetus. Eight groups of loose housed lactating mares with foals of Kladruby horse were studied at the National Stud Kladruby nad Labem (Czech Republic) from deliveries to abrupt weaning (at the age of 127 to 210 days). We recorded 10 848 suckling solicitations of 79 mare-foal pairs, from which 10 607 resulted in a suckling bout. In 41 cases a nursing mare became pregnant during lactation. We found no significant effect of pregnancy either on probability of the mother rejecting suckling solicitation of her foal or probability that she terminated a suckling bout. However the overall effect of mother’s pregnancy on suckling bout duration was not significant, there were considerable differences in pregnant and non-pregnant mares according to who terminated a suckling bout, whether the mother or the foal (F(1, 9776) = 12.1, P < 0.001). In case it was the mother then the suckling bout was longer if she was pregnant (65.36 ± 1.25 s) than barren (60.55 ± 1.36 s). We found no impact of pregnancy on duration of suckling bouts terminated by the foal. Further, nursing a foal during the first two trimesters of pregnancy had no negative impact on birth weight of the foetus. In conclusion, we found not higher, but a lower mother-offspring conflict in pregnant than in non-pregnant lactating mares while expecting just the opposite. We suggest that pregnant mares compensate their nursed foals during intensive stages of lactation through a relaxed mother-offspring conflict for later decrease in investment due to increasing demands of the foetus and/or for the shorter period of milk supply. Our results (partly published in Bartosova et al. 2011, PLoS ONE 6(8): e22068) are of high importance in horse breeding. One of the main arguments for early weaning of the foals is regeneration of their pregnant mothers before upcoming delivery. Here we present evidence that a pregnant mare “counts” with her dual maternal investment and “employs” evolutionary mechanisms enabling her to rear a vital foetus. From this point of view there is no objective reason for stressful weaning of her nursed offspring practised in conventional breeding. 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 aim of the study was to investigate the possibilities to use “number of years in competition” as a measure of durability in the genetic evaluation of Hungarian show-jumping horses. Competition results recorder between 1996 and 2009 in show-jumping competitions were used to estimate genetic parameters for number of years in competition. The results were collected by the Show-jumping Group of the Hungarian Horse Breeder’s Society. For estimation of genetic parameters for number of years in competition different linear mixed models were tested. In the first model, sex and birth year were taken into account as fixed effects. In the second model, an adjustment was made for age at first result in competition. The model fit was compared based on their determination coefficient. Variance components were estimated with VCE-6 software package. The determination coefficients of the models were 0.09 and 0.20, while the estimated heritability for number of years in competition was 0.27 and 0.23, respectively. |
