Title Behaviour Patterns of Horses Can be Used to Establish a Dominant-Subordinate Relationship Between Man and Horse Type Journal Article
Year 2003 Publication Abbreviated Journal Animal Welfare
Volume 12 Issue 4 Pages 705-708
Keywords animal welfare; behaviour patterns; dominance; unhandled horse
Abstract This paper describes how man can enter the social hierarchy of the horse by mimicking the behaviour and stance it uses to establish dominance. A herd is organised according to a dominance hierarchy established by means of ritualised conflict. Dominance relationships are formed through these confrontations: one horse gains the dominant role and others identify themselves as subordinates. This study was conducted using five females of the Haflinger breed, totally unaccustomed to human contact, from a free-range breeding farm. The study methods were based on the three elements fundamental to the equilibrium of the herd: flight, herd instinct and hierarchy. The trainer-horse relationship was established in three phases: retreat, approach and association. At the end of the training sessions, all of the horses were able to respond correctly to the trainer. These observations suggest that it is possible to manage unhandled horses without coercion by mimicking their behaviour patterns.

Title Untersuchung der „Schiefe“ des Pferdes:Symmetrie von Bewegungsablauf und Hufbelastung Type Book Whole
Year 2018 Publication Wissenschaftliche Reihe der Klinik für Pferde Abbreviated Journal
Volume Issue Pages
Keywords
Abstract Ziel der Studie war die Beschreibung der motorischen Lateralität („Schiefe“) gesunder adulter Pferde. Hierzu wurden 14 lahmfreie Pferde (10 Warmblüter, 4 Quarter Horses) auf dem Laufband in Schritt und Trab auf individuelle Abweichungen von der symmetri-schen Bewegung hinsichtlich Abstellung der Hinterhand, Wirbelsäulenform (Biegung), Vor- und Rückführung sowie Belastung von Vorder- und Hintergliedmaßen jeweils simul-tan hochfrequenzkinematographisch und kinetisch mittels resistiver Hufdrucksensoren untersucht. Zusätzlich wurden bevorzugte Abstellung und Biegung sowie Galopppräfe-renz klinisch bzw. reiterlich beurteilt, das Vorliegen einer Weideschrittpräferenz unter-sucht und Freilaufversuche (bevorzugte Abbiegerichtung, Ausweichrichtung um ein Hin-dernis, Galoppräferenz) durchgeführt. Keines der Pferde zeigte Symmetrie über alle Merkmale; zwar wurde bei jedem Merkmal für einzelne Probanden Symmetrie festgestellt, mit Ausnahme des Galopp-Freilaufver-suchs trat Asymmetrie jedoch häufiger auf. 12 Probanden zeigten in der Bewegungsana-lyse eine signifikante seitliche Abstellung (8x rechts (R), 4x links (L), mittlere seitliche Abweichung im Schritt 1,22°±1,09°, im Trab 1,05°±1,03°), 10 eine bevorzugte Biegung (9x L, 1x R), 13 signifikante Asymmetrien der Gliedmaßenvor- bzw. -rückführung und 12 eine signifikante asymmetrische Gliedmaßenbelastung für die normalisierte Spitzenkraft (PFN, peak force) bzw. den Impuls der Belastung (IN) an mindestens einem Beinpaar (alle Merkmale individuell wiederholbar). Linksabgestellte Pferde führten in beiden Gang-arten das rechte Hinterbein signifikant weiter zurück als nach rechts abgestellte Pferde, die tendenziell eher das linke Hinterbein weiter zurückführten. – Die auf dem Laufband festgestellten Asymmetrien traten in beiden Gangarten auf, aber nicht immer überein-stimmend, wobei die Richtung der bevorzugten Abstellung und ebenso der bevorzugten Biegung beim einzelnen Pferd in Schritt und Trab nie gegensätzlich waren. Jeder dieser beiden Parameter wurde daher für das einzelne Pferd über beide Gangarten zusammen-gefasst. Die Richtung von Abstellung und Biegung waren voneinander unabhängig, so-dass die Bewegungsmuster Abstellung ohne Biegung, Biegung ohne Abstellung, Abstel-lung mit Biegung in Laufrichtung (Travers) sowie Abstellung mit Biegung entgegen der Laufrichtung (Schulterherein) vorkamen. Kein Pferd war in beiden Merkmalen symmet-risch; für manche Pferde war neben der einfachen Biegung auch eine S-Form der Wir-belsäule signifikant. Die Belastungssymmetrie der Gliedmaßen war in beiden Gangarten von der Abstellung und der Biegung unabhängig, es gab aber Hinweise auf Zusammen-hänge zwischen bestimmten Kombinationen von Abstellung und Biegung einerseits und der Existenz einer Belastungsasymmetrie der Vorderbeine im Trab andererseits (unge-bogen mit Abstellung laufende und im Schulterherein laufende Pferde belasteten i.d.R. asymmetrisch).

8 Pferde wiesen eine signifikante Weideschrittpräferenz auf (5x L, 3x R), die bei ebenso vorhandener seitlicher Abstellung signifkant häufiger auf der der Abstellung abgewandten Seite auftrat. Sie wies keinen Zusammenhang mit der Rückführung der Hinterbeine im Schritt oder im Trab auf. Das Auftreten einer Weideschrittpräferenz war signifikant vom durch Abstellung und Biegung bestimmten Bewegungsmuster abhängig (Auftreten bei Abstellung ohne Biegung und bei Schulterherein, nicht bei Travers oder Biegung ohne Abstellung). Zudem zeigt die Präferenz der Pferde im Weideschritt eine starke Überein-stimmung mit der Belastungssymmetrie der Vorderbeine im Trab (bevorzugt vorgestelltes Bein wird mehr belastet (IN); symmetrische Belastung bei fehlender Präferenz). Im Hindernisversuch hatten 12 von 13 getesteten Probanden eine signifikant bevorzugte Ausweichrichtung (5x L, 7x R); diese war unabhängig von der gemessenen Wirbelsäulenform, lag aber bei Pferden mit seitlicher Abstellung überwiegend auf der Seite der gemessenen Abstellung. Im Abbiegeversuch zeigten 6 von 12 getesteten Probanden eine signifikant bevorzugte Abbiegerichtung (3x L, 3x R), diese war weder von der Abstellungsrichtung noch von der Wirbelsäulenform, der Weideschrittpräferenz oder der Belastungssymmetrie der Vorderbeine im Trab abhängig. Die meisten Pferde zeigten im Freilauf keine signifikante Galopppräferenz (2x L, 11x gerade (N), 1x R), wogegen reiterlich bei den meisten Pferden eine Präferenz festgestellt wurde; beide Beurteilungen stimmten ebenso wie die Beurteilungen verschiedener Reiter nicht miteinander überein. Die gemessene Abstellungsrichtung ließ sich durch visuelle Beobachtung mit hoher Si-cherheit vorhersagen. Die bevorzugte Wirbelsäulenform stimmte nicht mit der reiterlich oder an der Longe festgestellten Biegung überein, wohl aber mit der Seite, auf die die Mähne fällt. Die vorliegende Studie weist nach, dass individuell stabile motorische Lateralität, weitge-hend bestehend aus den den Merkmalen der reiterlich postulierten „Schiefe“, bei gesun-den Pferden in symmetrischen Gangarten besteht und dass zwischen bestimmten Merkmalen vorhersagbare Zusammenhänge bestehen. Daraus ergeben sich wertvolle Schlussfolgerungen für das reiterliche Geraderichten des Pferdes, für das in Übereinstimmung mit der Reitliteratur insbesondere die Lektion Schulterherein geeignet erscheint. Es ist gelungen, für die wesentlichen Merkmale Abstellung, Biegung und Belastungssymmetrie der Vordergliedmaßen im Trab klinische Tests aufzuzeigen, die mit hoher Sicher-heit die Ergebnisse der Bewegungsanalyse vorhersagen können, wobei Rückschlüsse auf weitere asymmetrische Merkmale möglich sind. Die reiterliche Beurteilung von bevor-zugter Biegung und Galopppräferenz scheint jedoch von weiteren Faktoren außer dem Pferd selbst abhängig zu sein und stimmt häufig nicht mit den messbaren Parametern überein. – In dieser Studie wird erstmals eine wissenschaftlich überprüfte und klinisch anwendbare Methode zur umfassenden Analyse der motorischen Lateralität im Sinne der „Schiefe“ eines Pferdes beschrieben.

Summary -“Crookedness“ in the Horse: Symmetry of Motion and Hoof Loading

The purpose of this study was description of motor laterality (in terms of “crookedness“) of sound adult horses. 14 non-lame horses (10 Warmblood horses, 4 Quarter Horses) were examined walking and trotting on a treadmill for individual motion asymmetry concerning keeping the hindlimbs at an angle (hindlimbs not tracking the frontlimbs, “hindquarter angle”), lateroflexion, pro- and retraction of the limbs as well as loading of front- and hindlimbs. High-speed-kinematography and resistive pressure sensors were used simultanously. The horses were also ridden to evaluate preferred lateroflexion and preferred lead in canter. Moving at an angle towards a preferred side was assessed visually. Laterality of grazing stance was tested, as well as preferred turning direction, obstacle avoidance direction and preferred lead in canter while moving unrestrained in an arena. None of the horses moved symetrically over all traits; although there were symmetrical traits with individual horses, asymmetry was more commen (except for the unrestrained preferred lead test). On the treadmill, 12 horses moved with their hindquarters significantly at a angle (8x right (R), 4x left (L), mean lateral angle 1,22°±1,09° at a walk and 1,05°±1,03° at a trot), 10 showed laterality for lateroflexion (9x L, 1x R), 13 had significant asymmetries for protraction and/ or retraction and 12 for loading of contralateral limbs concerning normalized peak force (PFN) and impulse (IN), respectively, of at least one pair of limbs (all with good repeatibility). Horses keeping their hindquarters to the left showed significantly larger retraction of the right hindlimb compared to horses keeping their hindquarters to the right, who tended to further retract the left hindlimb. – Asymmetries found on the treadmill occurred in both gaits but were not always the same in both gaits, though the direction of the hindquarter angle as well as that of the preferred lateroflexion never contradicted each other within the same individual. Therefore, a specific laterality direction of hindquarter angle and lateroflexion could be assigned to each horse. The direction of preferred hindquarter angle and lateroflexion, respectively, were independent of each other so that the movement patterns “hindquarter angle without lateroflexion”, “lateroflexion without hindquarter angle”, “hindquarter angle with lateroflexion to the same side” (hindquarter-in/ travers) and “hindquarter angle with lateroflexion to opposite sides” (shoulder-in) could be found; no horse moved symmetrical for both traits. The lateroflexion of some horses could even be regarded as a double bend. At both gaits, symmetry of limb loading was independent of hindquarter angle as well as lateroflexion, taken seperately; still, there seems to be a relation between certain combinations of hindquarter angle and lateroflexion, on the one side, and the existence or absence of asymmetric loading of the frontlimbs in trot (horses moving with hindquarter angle, but without lateroflexion, and horses moving in shoulder-in mostly had asymmetric frontlimb loading).

238 7. Summary8 horses displayed laterality for a grazing stance (5x L, 3x R); their hindquarter angle, if they showed one, was significantly more often on the opposite side of their advanced frontleg while grazing. The direction of the grazing stance was independent of hindlimb retraction symmetry in either gait. Occurrence of grazing stance laterality significantly depended on the movement pattern consisting of hindquarter angle and lateroflexion (horses moving with a hindquarter angle, but without lateroflexion, and horses moving in shoulder-in mostly showed grazing stance laterality, while horses moving with lateroflexion, but without a hindquarter angle, and horses moving in hindquarter-in did not). Also, grazing stance laterality was highly predictive of the symmetry of frontlimb loading at trot (advanced frontleg has significantly higher impulse (IN) at trot; horses without grazing stance laterality showed symmetrical impulse). 12 of 13 horses displayed laterality for obstacle avoidance direction (5x L, 7x R) that was independent of the individually preferred lateroflexion but if the horses showed a hindquarter angle it was usually to the same side. 6 of 12 horses showed laterality for turning direction (3x L, 3x R) that had no relation to laterality of either hindquarter angle, lateroflexion, grazing stance or frontlimb loading symmetry at trot. Most horses had no significant lead preference in the unrestrained canter test (2x L, 11x no preference (N), 1x R) even though riders assigned a lead preference to most horses; both ratings did not match, as well as the rating between two different riders did not match. The (measured) direction of hindquarter angle was highly predictable by visual asessment. Preferred (measured) lateroflexion did not match the direction of lateroflexion assigned by either rider or on the long line; it was in agreement with the mane side of the horse, though. This study proves that individual and stable motor laterality exists in sound horses in symmetrical gaits, mostly consisting of the traits that are hypothesized as “crookedness” in riding literature. It also shows that predictible relationships exist between certain traits thereof. This knowledge is valuable since it has implications for the training of riding horses for straightness, wherefore especially riding shoulder-in should be helpful. Relatively easy clinical tests could successfully be found that allow well predicting main features of individual horses ́ motor laterality like hindquarter angle, lateroflexion and frontlimb loading symmetry at trot as measured on the treadmill. Some conclusions can also be drawn for other asymmetrical traits. The asessment of preferred lateroflexion and canter lead performed by riders, though, seems to also underlie other influences than the horse itself and failed to be a predictor of the measured traits. – For the first time, a scientifically proven and clinically applicable method of asessing a horses motor laterality in terms of “crookedness” is presented.

Title Validation of smart textile electrodes for electrocardiogram monitoring in free-moving horses Type Journal Article
Year 2017 Publication Journal of Veterinary Behavior: Clinical Applications and Research Abbreviated Journal J. Vet. Behav.
Volume 17 Issue Pages 19-23
Keywords
Abstract This article focuses on the validation of smart textile electrodes used to acquire electrocardiogram (ECG) signals in horses in a comfortable and robust manner. The performance of smart textile electrodes is compared with standard Ag/AgCl electrodes in terms of the percentage of motion artifacts (MAs, the noise that results from the movement of electrodes against the skin) and signal quality. Seven healthy Standardbred mares were equipped with 2 identical electronic systems for the simultaneous collection of ECGs. One system was equipped with smart textile electrodes, whereas the second was equipped with standard Ag/AgCl electrodes. Each horse was then monitored individually in a stall for 1 hour, without any movement constraints. The ECGs were visually examined by an expert who blindly labeled the ECG segments that had been corrupted by MAs. Finally, the percentage of MAs (MA%) was computed as the number of samples of the corrupted segments over the whole length of the signal. The total MA% was found to be lower for the smart textiles than for the Ag/AgCl electrodes. Consistent results were also obtained by investigating MAs over time. These results suggest that smart textile electrodes are more reliable when recording artifact-free ECGs in horses at rest. Thus, improving the acquisition of important physiological information related to the activity of the autonomic nervous system, such as heart rate variability, could help to provide reliable information on the mood and state of arousal of horses.

Title Social licking pattern and its relationships to social dominance and live weight gain in weaned calves Type Journal Article
Year 1984 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 12 Issue 1 Pages 25-32
Keywords
Abstract Social licking patterns of heifer and steer herds were observed and recorded during periods of resting and intermittent feeding. The results revealed the following features: (1) heifers and steers had 15.0 and 15.2 social licking interactions per hour which lasted for 37.8 and 41.0 s on average, respectively. The average time an animal spent licking was about 25 s per hour; (2) all the animals in the herds were licked by others, but only 72.3% of the animals licked other animals; (3) the animals close in the social hierarchy tended to lick each other for a longer time than did remote animals; (4) the time receiving l licking and weight gain tended to be positively correlated. The observations suggest that (1) the motivation of giving licking may be individual-specific and may be influenced by genetic factors, while that of receiving licking appears to be general, and that (2) social licking may mean not only cleaning the skin and hair of a passive partner, but also leading it to psychological stability.

Title Over-flexing the horse's neck: A modern equestrian obsession? Type Journal Article
Year 2010 Publication Journal of Veterinary Behavior: Clinical Applications and Research Abbreviated Journal Journal of Veterinary Behavior: Clinical Applications and Research
Volume 5 Issue 4 Pages 180-186
Keywords
Abstract We used an opportunistic review of photographs of different adult and juvenile horses walking, trotting, and cantering (n = 828) to compare the angle of the nasal plane relative to vertical in feral and domestic horses at liberty (n = 450) with ridden horses advertised in a popular Australian horse magazine (n = 378). We assumed that horses in advertisements were shown at, what was perceived by the vendors to be, their best. Of the ridden horses, 68% had their nasal plane behind the vertical. The mean angle of the unridden horses at walk, trot, and canter (30.7 ± 11.5; 27.3 ± 12.0; 25.5 ± 11.0) was significantly greater than those of the ridden horses (1.4 ± 14.1; ?5.1 ± ?11.1; 3.1 ± 15.4, P < 0.001). Surprisingly, unridden domestic horses showed greater angles than feral horses or domestic horses at liberty. We compared adult and juvenile horses in all 3 gaits and found no significant difference. Taken together, these findings demonstrate that the longitudinal neck flexion of the degree desirable by popular opinion in ridden horses is not a common feature of unridden horses moving naturally. Moreover, they suggest that advertised horses in our series are generally being ridden at odds with their natural carriage and contrary to the international rules of dressage (as published by the International Equestrian Federation). These findings are discussed against the backdrop of the established doctrine, which states that carrying a rider necessitates changes in longitudinal flexion, and in the context of the current debate around hyperflexion.
