Title The influence of challenging objects and horse-rider matching on heart rate, heart rate variability and behavioural score in riding horses Type Journal Article
Year 2012 Publication The Veterinary Journal Abbreviated Journal
Volume 192 Issue 1 Pages 75-80
Keywords Horse-rider interaction; Horse compliance; Welfare; Heart rate; Behaviour score
Abstract A good horse-rider ‘match’ is important in the context of equine welfare. To quantify the influence of repetition and horse-rider matching on the stress of horses encountering challenging objects, 16 Warmblood horses were ridden in a test-setting on three occasions. On each occasion the horse was ridden by a different rider and was challenged by three objects (A–C). Heart rate (HR), heart rate variability (HRV) of horse and rider, and behaviour score (BS) of the horse were obtained for each object and as a total for each test. The horse-rider interaction was evaluated with each combination and assessed as ‘matching’ or ‘mismatching’, and the horses were categorised as ‘compliant’, ‘partly-compliant’ or ‘non-compliant’. Horses exhibited a decreased HR (P = 0.015) and a decreased BS (P = 0.004) within and across different tests. ‘Matching’ horse-rider combinations exhibited less stress as indicated by reduced HR (‘match’ 69 ± 10 vs. ‘mismatch’ 72 ± 9, P = 0.001) and BS (‘match’ 1.9 ± 1.1 vs. ‘mismatch’ 3.8 ± 1.4, P = 0.017) of the horse. ‘Compliant’ (68 ± 8, P < 0.001) and ‘partly-compliant’ (71 ± 9, P = 0.002) horses had significantly lower HR than ‘non-compliant’ (75 ± 9) animals. The findings of the study indicate that HR and BS measurements support a subjective ‘match’ diagnosis and HR measurement may be a valuable tool in assessing horse compliance.

Title Die Bedeutung des Leerkauens bei Pferden aus Sicht der Physiologie und der Ethologie Type Manuscript
Year 2012 Publication Abbreviated Journal
Volume Issue Pages
Keywords
Abstract Der Umgang mit Pferden erfreut sich immer größerer Beliebtheit. Aufgrund des Verhaltens können Rückschlüsse auf die Befindlichkeiten der Tiere gezogen werden

(TSCHANZ et al. 1997a). Je mehr wir über das Verhalten der Tiere wissen, desto besser können wir in der Haltung, Ausbildung und Nutzung der Pferde dazu beitragen, die Lebensbedingungen zu verbessern und den Ansprüchen der Pferde gerechter zu werden.

Bei der Ausbildung von Pferden kommen u.a. aus Amerika neue Einflüsse auf Ausbildungsmethoden zu uns. Es wird dabei immer wieder ein „Kauen“ der Pferde während des Trainings beschrieben, doch gibt es keine wissenschaftlichen ntersuchungen darüber.

Eine Kaubewegung des Pferdes außerhalb der Futteraufnahme wird als „Leerkauen“

definiert. Es ist eine „horizontale Bewegung“ des Unterkiefers gegen den Oberkiefer zu beobachten, vergleichbar mit der Mahlbewegung (Abbildung 1). Häufig ist während des Leerkauens eine Anspannung des oberflächlichen Kaumuskels vom unteren Unterkieferrand aus in Richtung Jochbogen/Crista facialis zu erkennen.

Eine Sonderform des Leerkauens stellt die sogenannte Unterlegenheitsgebärde (UG)

dar (ZEEB 1959b). Es handelt es sich um eine „vertikale Bewegung“ der Unter- und

Oberkiefer voneinander weg und aufeinander zu (Abbildung 2). Ihre Funktion ist die

Beschwichtigung. Unter dem Begriff Leerkauen wird in dieser Dissertation immer die

horizontale Mahlbewegung verstanden.

Title From Social Network (Centralized vs. Decentralized) to Collective Decision-Making (Unshared vs. Shared Consensus) Type Journal Article
Year 2012 Publication PLoS ONE Abbreviated Journal PLoS ONE
Volume 7 Issue 2 Pages e32566 EP -
Keywords
Abstract <p>Relationships we have with our friends, family, or colleagues influence our personal decisions, as well as decisions we make together with others. As in human beings, despotism and egalitarian societies seem to also exist in animals. While studies have shown that social networks constrain many phenomena from amoebae to primates, we still do not know how consensus emerges from the properties of social networks in many biological systems. We created artificial social networks that represent the continuum from centralized to decentralized organization and used an agent-based model to make predictions about the patterns of consensus and collective movements we observed according to the social network. These theoretical results showed that different social networks and especially contrasted ones – star network vs. equal network – led to totally different patterns. Our model showed that, by moving from a centralized network to a decentralized one, the central individual seemed to lose its leadership in the collective movement's decisions. We, therefore, showed a link between the type of social network and the resulting consensus. By comparing our theoretical data with data on five groups of primates, we confirmed that this relationship between social network and consensus also appears to exist in animal societies.</p>

Title Identifying potential risk situations for humans when removing horses from groups Type Journal Article
Year 2012 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 136 Issue 1 Pages 37-43
Keywords Equine; Group; Human; Handling; Injury
Abstract Removing a horse from its social group may be considered risky, both for the handler and the horse, because other horses can interfere in the catching process. The main aim of this study was to identify where and when these risk situations occur while removing a horse from its group. A potential risk situation was defined by the closeness of loose horses in the group or by any physical contact with them. Whether the number of horses following would be influenced by the social rank of the horse being led out, and whether more horses would follow to the gate when a larger proportion of the group was removed compared to when a single horse was taken out were also investigated. Thirty-two mares (1–2 years) were kept in groups of four. All horses were taken out of their home paddock twice alone (64 tests) and twice with a companion (32 tests). One handler (or two handlers when two horses were removed) was asked to approach (phase 1) and catch the target horse (phase 2), walk it to the centre of the paddock and remain stationary at a post for 30 s (phase 3), walk to the paddock entrance (phase 4) and through the gate (phase 5). The number of horses following, and the number of loose horses in proximity (<2 m, 2–5 m) to the target horse and handler was estimated, and horse–horse and horse–human interactions were recorded continuously for the five scoring phases. Significantly more loose horses were within 2 m of a single target horse during the phases approach (mean ± SD: 1.5 ± 0.8), catch (1.6 ± 0.9) and post (1.7 ± 0.7) than during walk (1.0 ± 0.5) and gate (1.1 ± 0.6). Rank did not influence the number of horses following to the gate (high rank: 2.4 ± 0.7; lower rank: 2.0 ± 1.0; P = 0.396) and interactions between horses were rare. A greater proportion of the loose horses followed when two horses (0.9 ± 0.2) were removed compared to when a single horse (0.7 ± 0.3) was taken out (P = 0.011). In conclusion, maintaining a distance to other horses in the group by reducing the time being relatively stationary, so giving loose horses fewer chances to approach, is likely to contribute to improved handler's safety. Removing a small proportion of the group may also decrease the probability of the other horses following.
