  Title Behavioural and physiological responses of therapy horses to mentally traumatized humans Type Journal Article
  Year 2018 Publication Applied Animal Behaviour Science Abbreviated Journal  
  Volume Issue Pages (up)  
  Keywords Equine-assisted therapy; Ptsd; Horse; Behaviour; Cortisol; Heart rate  
  Abstract The benefits to humans of equine-assisted therapy (EAT) have been well-researched, however few studies have analyzed the effects on the horse. Understanding how differing mental states of humans affect the behaviour and response of the horse can assist in providing optimal outcomes for both horse and human. Four humans clinically diagnosed and under care of a psychotherapist for Post-Traumatic Stress Disorder (PTSD) were matched physically to four neurotypical control humans and individually subjected to each of 17 therapy horses loose in a round pen. A professional acting coach instructed the control humans in replicating the physical movements of their paired PTSD individual. Both horses and humans were equipped with a heart rate (HR) monitor recording HR every 5secs. Saliva samples were collected from each horse 30 min before and 30 min after each trial to analyze cortisol concentrations. Each trial consisted of 5 min of baseline observation of the horse alone in the round pen after which the human entered the round pen for 2 min, followed by an additional 5 min of the horse alone. Behavioural observations indicative of stress in the horse (gait, head height, ear orientation, body orientation, distance from the human, latency of approach to the human, vocalizations, and chewing) were retrospectively collected from video recordings of each trial and analyzed using a repeated measures GLIMMIX with Tukey's multiple comparisons for differences between treatments and time periods. Horses moved slower (p < 0.0001), carried their head lower (p < 0.0001), vocalized less (p < 0.0001), and chewed less (p < 0.0001) when any human was present with them in the round pen. Horse HR increased in the presence of the PTSD humans, even after the PTSD human left the pen (p < 0.0001). Since two of the PTSD/control human pairs were experienced with horses and two were not, a post-hoc analysis showed that horses approached quicker (p < 0.016) and stood closer (p < 0.0082) to humans who were experienced with horses. Horse HR was lower when with inexperienced humans (p < 0.0001) whereas inexperienced human HR was higher (p < 0.0001). Horse salivary cortisol did not differ between exposure to PTSD and control humans (p > 0.32). Overall, behavioural and physiological responses of horses to humans are more pronounced based on human experience with horses than whether the human is diagnosed with a mental disorder. This may be a reflection of a directness of movement associated with humans who are experienced with horses that makes the horse more attentive. It appears that horses respond more to physical cues from the human rather than emotional cues. This knowledge is important in tailoring therapy programs and justifying horse responses when interacting with a patient in a therapy setting.

  Title Social learning in Horses: Differs from individual learning only in the learning stimulus and not in the learning mechanisms Type Abstract
  Year 2018 Publication 14th Meeting of the Internatinoal Society for Equitation Science Abbreviated Journal 14th Meeting ISES  
  Volume Issue Pages (up)  
  Keywords horse; individual learning; learning mechanisms; learning stimuli; social learning  
  Abstract Equine welfare can be enhanced by applying species specific training. This may incorporate social learning, as horses are highly social and social stimuli are of primary importance. Social learning is comparable to individual learning in its learning mechanisms, differing primarily in the way it is stimulated. Our initial study showed that horses of different breeds (N = 38) follow humans after observing other horses doing so, but only if the observed horse was familiar to and higher ranking than the observer (Fisher's exact test: N = 12, P = 0.003). A second study showed that horses and ponies (N = 25) learned to pull a rope to open a feeding apparatus after observing demonstrations by conspecifics, again, only if the demonstrating horse was older and higher ranking than the observer (Fisher's combination test, N = 3, v2 = 27.71, p = 0.006). Our third approach showed that horses and ponies (N = 24) learned to press a switch to open a feeding apparatus after observing a familiar person (GzLM: N = 24, z = 2.33, P = 0.02). Most recently, we confronted horses and ponies (N = 50) with persons demonstrating different techniques for opening a feeding apparatus. In this study we investigated whether the horses would copy the demonstrators' techniques or apply their own. Here only some horses copied the technique, and most of the successful learners used their mouths irrespective of the demonstrators' postures (Chi Square Test: N = 40, df = 2, &#967;2 = 31.4, p < 0.001). In all the approaches social stimuli elicited learning processes in the test horses, while only a few individuals in the control groups mastered the tasks by individual learning. The following behaviour observed in the initial study may have been facilitated by a social stimuli (social facilitation), and the opening of the feed boxes in the subsequent studies appear to be mostly the result of enhancement (social enhancement). Some horses may have used the social stimuli at first and continued their learning process by individual trial and error. However, the horses were also selective in whom and some in how to copy. This may have been conditioned (socially conditioned) or the result of simple forms of reasoning on the reliability of the particular information provided by demonstrators of certain social ranks or social positions, as high ranking and familiar horses and familiar persons were copied and some imitated exactly.

Lay person message: Traditional riding instructions suggest that horses learn by observing other horses. For example, older, more experienced driving horses are used for initial training of young driving horses. We have shown that horses indeed use learning stimuli provided by other horse, as well as by humans. Horses readily accept stimuli observed in high ranking and familiar horses, and familiar persons. Such stimuli elicit learning processes which are comparable to individual learning. We suggest applying social learning whenever possible, as it is much faster and less stressful than individual learning, where learners experience negative outcomes in trial and error learning.

  Title Fallstudie zum Platzangebot, Verhalten und Wohlbefinden der Pferde (Equus caballus) in Mehrraum-Außenlaufställen mit Aus-lauf und Bewegungsställen [A case study to space, behavior and well-being of horses (Equus caballus) in open stables and open active stables] Type Manuscript
  Year 2014 Publication KTBL Schriften Abbreviated Journal  
  Volume Issue Pages (up)  
  Keywords  
  Abstract Verhaltensbeobachtungen erfolgten an 112 Pferden in Mehrraum-Außenlaufställen mit Auslauf und Bewegungsställen. Bei vermehrtem Platzangebot sinkt das agonistische Verhalten in Bewegungsställen außerhalb des Fressbereiches. Mit zunehmender Stallgröße (überdachte Fläche und Auslauf) steigt in beiden Haltungsverfahren das affiliative Verhalten während das agonistische Verhalten mit Verletzungsrisiko sinkt. Daher wird für beide Haltungsverfahren ein möglichst großzügiger Stall je Pferd empfohlen. Die beobachteten Erkrankungen der letzten zwölf Monate zeigen vermehrt Hautkrankheiten in den Mehrraum-Außenlaufställen mit Auslauf, wohingegen Hufgeschwüre in Bewegungsställen auftraten. Wird der Fütterungsaspekt in den Bewegungsställen betrachtet, so ist die Transponderfütterung in Kombination mit ad libitum Fütterung aufgrund des deutlich geringeren, agonistischen Verhaltens beim Fressen, der reinen Transponderfütterung vorzuziehen. Mehrraum-Außenlaufställe mit Auslauf haben den Vorteil der synchronen Nahrungsaufnahme.

[The behaviour of 112 horses was observed in open stables and open active stables. Horses show less agonistic behaviour outside of the feeding area in open active stables as the space for each horse is augmented. Also the affiliative behaviour increases as a function of more space per horse while agonistic behaviour with a risk for injury decreases. These results are independent from the husbandry system. Due to this fact a stable with a larger area per horse is recommended. Diseases of the last twelve month were recorded and show skin diseases in open stables and abscesses in the hooves in open active stables. To consider the feeding in open active stables it was found that horses which were fed with hay controlled by transponders showed more agonistic behaviour in contrast to horses being fed using transponders but with access to hay ad libitum. Thus transponder feeding in combination with ad libitum feeding is recommended. Open stables have the advantage of synchronized feeding.]

  Title Dominance Hierarchies in Horses: Comparing and Contrasting Different Methods for Assessing Hierarchies Type Journal Article
  Year 2016 Publication Ursidae: The Undergraduate Research Journal at the University of Northern Colorado Abbreviated Journal  
  Volume 5 Issue 3 Pages (up)  
  Keywords  
  Abstract Understanding animal social structures is imperative when it comes to the care, housing and handling of large herd animals. Knowing how hierarchies are structured, along with environmental and physiological aspects that may affect them, will allow owners and breeders to house and care for their animals. The aim of my study was to better understand two methods used to assess dominance hierarchies in horses, Equus caballus, and to predict which method would be more useful for owners housing domestic horses. I designed an experiment where I compared a structured method, the paired feeding test, with behavioral observations from the horses’ natural setting. I hypothesized that the structured method would not conclude the same dominance hierarchy as the natural observations. I also hypothesized that traits of the horses, such as size or age, would correlate with the hierarchy ranking within a herd. A herd of six individual horses from a small ranch east of Platteville, Colorado was used to test the two methods. I found that the two methods measured different hierarchies. The paired feeding test showed no correlations to any of the physical measurements, as well as did not provide a hierarchy that was similar to the natural dominance observations of the horses. Natural observations established a more linear hierarchy and had significant correlations with weight and overall body size. The results indicate that the paired feeding test may not be a valid method for establishing dominance hierarchies within domestic horses housed in a small range.

I recommend use of natural observations over paired feeding tests for ranchers, breeders or owners trying to understand the dominance hierarchies among their herds.

  Title Vergleich verschiedener Methoden zur Angstextinktion bei Pferden Type Manuscript
  Year 2006 Publication Abbreviated Journal  
  Volume Issue Pages (up)  
  Keywords  
  Abstract Pferde sind Fluchttiere. Ihr Fluchtinstinkt bewirkt, dass sie sich leicht erschrecken und auch in

diversen Situationen mit Flucht reagieren. Diese Tatsache ist den meisten Reitern bekannt,

nur ist es für den Menschen teilweise schwer, mit dieser Eigenschaft auszukommen und sie zu

verstehen oder gar nachzuvollziehen. So kommt es häufig zu Unfällen, die aus der Angst der

Pferde resultieren, jedoch vermeidbar gewesen wären, hätte man ankündigende Signale früher

erkannt. Des Weiteren kann die Angst eines Pferdes auch durch eine (Ver-) Weigerung,

bestimmte Dinge zu tun, sichtbar werden. Diese Weigerung wird in der Reiterei gerne als

„Bockigkeit“ und „Ungehorsam“ des Pferdes interpretiert und führt nicht selten zu einer

Bestrafung. Insgesamt kann man sagen, dass angstauslösende Reize und die Reaktionen des

Pferdes darauf oft falsch eingeschätzt oder falsch interpretiert werden und in der Folge auch

falsch damit umgegangen wird. Ein Grund dafür ist sicher das fehlende Wissen über das

Verhalten des Pferdes. Mit der vorliegenden Diplomarbeit soll ein Beitrag geleistet werden,

das Pferd in seinem Angstverhalten besser zu verstehen. Ziel der Arbeit war es, das Verhalten

des Pferdes bei verschiedenen Intensitäten von Angst zu untersuchen. Des Weiteren wurden

Methoden untersucht, mit denen man die Angst von Pferden vor bestimmten Reizen und

Situationen potentiell lindern kann, was letztendlich auch der Unfallvorbeugung dient.

Die vorliegende Diplomarbeit wurde am Haupt- und Landesgestüt Marbach durchgeführt; 24

Junghengste standen hierfür zur Verfügung. Darunter waren 18 Deutsche Warmblüter, 3

Vollblutaraber und 3 Schwarzwälder Füchse (Kaltblüter), somit war auch ein Rassenvergleich

möglich.

In einem ersten Teil der Arbeit wurde untersucht, wie sich Angst bei Pferden äußert. Hierfür

wurde ausgenutzt, dass Pferde ganz generell vor unbekannten, neuen Gegenständen Angst

haben (= Neophobie). Zur Angstauslösung dienten als Konfrontationsgegenstände ein

Sonnenschirm und eine Plastikplane. Beide Gegenstände waren für die Testpferde unbekannt.

Das Verhalten sowie die Herzrate der Tiere wurden während aller Versuche beobachtet und

quantifiziert. Nacheiner ersten Konfrontation wurden die Pferde an die Objekte gewöhnt

(Extinktionstraining = Angstlöschung) und beobachtet welche Verhaltensymptome sich

während dieser Gewöhnung (= Verlust der Neophobie) verändern. Die Hypothese war, dass

tatsächliche Angstsymptome während der Gewöhnung immer seltener zu beobachten sind.

Zusammenfassung III

Als Verhaltensweisen für Angst konnten Ausweichbewegungen und Flucht, Lautäußerungen

(Prusten und Schnauben), das Anspannen der Halsmuskulatur sowie das Vordrücken der

Oberlippe identifiziert werden. Darüber hinaus wurde gezeigt, dass Abstufungen im

Angstverhalten möglich sind: Bei sehr hohem Angstlevel sind Fluchtreaktionen zu

beobachten. Bei mittlerem Angstlevel treten Ausweichbewegungen im Schritt und

Lautäußerungen (Prusten und Schnauben) auf, bei geringem Angstlevel wird die

Halsmuskulatur angespannt und die Oberlippe vorgedrückt.

Im Zweiten Teil der Arbeit sollten verschiedene Methoden zur Angst-Extinktionauf ihre

Wirksamkeit hin untersucht werden. Verwendet wurde in verschiedenen Testgruppen die

Methode der Desensibilisierung (d.h. leichte, schrittweise stärker werdende Exposition

gegenüber dem angstauslösenden Reiz), die Desensibilisierung mit Gegenkonditionierung

(positive Verstärkung) durch Streicheln bzw. Reiben des Halses und die Desensibilisierung

mit Gegenkonditionierung durch Futterbelohnung. Als Kontrollgruppe dienten Pferde, die

ohne eine Konfrontation mit dem angstauslösenden Reiz nur über den Versuchplatz geführt

wurden.

Während des Extinktionstrainings konnte beobachtet werden, dass die Desensibilisierung mit

Gegenkonditionierung zu einer schnelleren Extinktion führt als ohne Gegenkonditionierung.

Allerdings zeigte ein Vergleich mit der Kontrollgruppe, die das Extinktionstraining nicht

erfahren hatte, den gleichen Verlust an Angstverhalten wie die Gruppen mit Extinktionstraining.

Dieses Ergebnis wurde so interpretiert, dass die wiederholte Exposition gegenüber

angstauslösenden Reizen bei den durchgeführten Verhaltenstests zwar eine Rolle spielt, doch

dass auch allein die Beschäftigung mit den Tieren zu einem Verlust von Angstverhalten führt

(wahrscheinlich auch aufgrund eines wachsenden Vertrauens zur Führperson, die über das

komplette Experiment hin die Gleiche blieb).

  Title Car Accident Due to Horse Crossing the Motorway: Two Case Reports Type Journal Article
  Year 2017 Publication The Bulletin of Legal Medicine Abbreviated Journal Bull. Leg. Med.  
  Volume 22 Issue Pages (up)  
  Keywords animal vehicle collision, death, disability, horse, injury, motorway  
  Abstract Basic Commercial Court in Ankara wanted a report from our department of forensic medicine about two injury cases due to animal vehicle collision. The reports should include the disability rate and the duration of unfunctionality. After the examination we prepared the reports. Both vehicle collisions happened due to free ranging horse crossing the motorway. Both cases had different types of injury due to trauma. Vehicle collision due to horse crossing the motorway is rarely met in Turkey.

Our first case is a man that had upper extremity and facial injury. He uses prothesis due to ear amputation. He has a scar tissue on the right side of his face and left forearm. The other case is three-years-old boy that had cranial bone fracture and cranial hematoma. He has also hemiparesis of the right side of body. Both cases have neurologic sequels but they have no psychiatric sequels.

In literature, animal vehicle collisions involve lots of animal species such as kangaroo, deer, camel and moose. Animal vehicle collision involving the horses is rarely met. Forensic medicine specialists should state the causal link between traumatic events and disabilities in order to help justice. Our aim to present the current two cases is investigation of injuries of animal related collision and makes forensic medicine specialists pay attention to the subject of preparing reports about such cases.
