  Abstract Das Droh- und Meideverhalten von 270 Pferden wurde im Fressbereich von 10 Offenlaufställen

mit Fressständen und 11 Offenlaufställen mit computergesteuerten Abrufstationen

anhand von visuellen kontinuierlichen Direktbeobachtungen erfasst. Diese erfolgten je Betrieb

über einen 24-Stunden-Tag, der nach dem Tortenstückverfahren (6x4 Stunden) zusammengesetzt

war.

Insgesamt wurden 6297 agonistische Verhaltensweisen in, vor und hinter den

Fütterungseinrichtungen registriert (Meiden 40,6 %, Verdrängen 12,8 %, Beißen/ Hinterhandschlag/

Angehen 12,7 % und Drohen/ Drohbeißen/ Hinterhanddrohen 33,9 %). In den

Futterstationen wurden 22,5 % dieses Verhaltens beobachtet, vor und hinter den Futterstationen

77,5 %. Bei den Betrieben mit Fressständen fanden 31 % der agonistischen Verhaltensweisen

in den Ständen statt, bei den Betrieben mit Abruffütterung 21 %.

Der Einfl uss des einzelnen Betriebes (innerhalb Fütterungssystem) auf die agonistischen

Verhaltensweisen vor und hinter den Fütterungseinrichtungen war signifi kant. Die Auswertung

ergab, dass Drohgesten im Wartebereich von Abrufstationen häufi ger auftreten

als in dem von Fressständen. Demgegenüber können Pferde in Abrufstationen ungestörter

fressen. Insgesamt betrachtet war jedoch die Anzahl an sozionegativen Interaktionen im

Bereich der Futtereinrichtungen bei beiden Fütterungssystemen gering. Die agonistischen

Verhaltensweisen wurden zusätzlich noch von der Heumenge und dem Konstitutionstyp

beeinfl usst.

Der Betrieb erwies sich als maßgeblicher Einfl ussfaktor. Als Resümee ergibt sich, dass

bei ordnungsgemäßer Gruppenhaltung mit fachgerechtem Management beide Fütterungssysteme

für Pferde im Offenlaufstall geeignet sind.

[The threatening and avoiding behaviour of 270 horses living in run-out sheds was observed

at 10 stables with feeding stalls and at 11 stables with automatic feeding systems for hay

and concentrates. Every group of horses was observed on five succeeding days visually

and immediately for 6 sessions, each of 4 hours. These 6 slices form together 24 hours, a

complete day.

Altogether, 6297 agonistic behaviour patterns were registered in front of, inside and

behind the feeding stations (avoiding behaviour 40.6 %, edging out of others 12.8 %,

biting/rear leg kicking/charging 12.7 % und threatening/biting threats/rear leg kicking

threats 33.9 %). 22.5 % of these types of behaviour were recorded in the feeding stations,

77.5 % together in front and behind of these. In the stables with feeding stalls there were

31 % of the observed threatening gestures inside the feeding stations, in the stables with

automatic feeders only 21 %.

The individual farm showed signifi cant infl uence on the modes of agonistic behaviour

in front and behind the feeding facilities. Threatening gestures happen more often in the

waiting area of automatic feeders than in that of feeding stalls. On the other hand horses

in computer controlled systems will be less disturbed at eating. All together the number

of negative interactions in the feeding area at both feeding systems was relatively low.

In addition the agonistic behaviour was infl uenced by the quantity of hay and the constitutional

typ of the horses.

Because of the management of the individual stable exercises the most substantial

infl uence on the behaviour of the horses, it can be said, that, correct group keeping with

professional management provided, both feeding systems are suitable for horses in run-in

sheds.]

  Title Abrufautomaten für Pferde im Offenlaufstall im Vergleich – Besuchshäufigkeit, Aufenthaltsdauer und Anzahl an Auseinandersetzungen [A comparison of automatic feeding systems for horses in run-out-sheds – frequency of visit, duration of stay and number of conflicts] Type Book Chapter

  Abstract In 32 Offenlaufställen mit computergesteuerten Abrufstationen wurden die Aufenthaltsdauer

und Besuchshäufigkeit sowie das Droh- und Meideverhalten von 439 Pferden im

Füttererungsbereich erfasst. Je Betrieb erfolgten visuelle kontinuierliche Direktbeobachtungen

nach dem Tortenstückverfahren (6 x 4 Stunden) für je einen 24-Stunden-Tag.

Ziel war die Überprüfung der verschiedenen Bauausführungen der Abrufstationen unter

dem Aspekt der Tiergerechtheit. Eine Einwegstation reduzierte signifikant die Anzahl an Auseinandersetzungen

im Fütterungsbereich. Demgegenüber führten die für das fressende Pferd

tiergerechten Varianten (Fressstand mit Eingangssperre und ohne Austreibehilfe) zu einer

Erhöhung der Besuchshäufigkeit und Aufenthaltsdauer und somit auch zu einer erhöhten

Anzahl an Drohgesten. Doch insgesamt betrachtet, kann die Anzahl an sozionegativen

Interaktionen im Fütterungsbereich der Abrufstationen als relativ gering eingestuft werden.

Da sich außerdem der Betrieb (Management, Fläche, Konzeption) als maßgeblicher Einflussfaktor

auf die überprüften Parameter erwies, dürften die Unterschiede in der Bauausführung

der derzeitigen Abrufstationen für Pferde eher von untergeordneter Bedeutung sein.

[Duration of stay, frequency of visit, threatening gestures and behaviour of avoidance of

439 horses was observed at the feeding area of 32 run-out-sheds. The observation was based

on the method of visual continuously direct watching after the pie chart system (6 x 4 hours)

over a period of 24 hours. The observation should show which construction of the different

automatic feeding systems corresponded best under the aspect of animal welfare.

It was obvious that the one-way-station reduced significantly the number of conflicts

in the feeding area, whereas those systems which are appropriate for the eating horses

(feeding station with access barrier and without stimulation device by electric shock) led

to a higher frequency of visits and duration of stay as well as to more threatening gestures.

Considering altogether, the number of negative interactions in the feeding area of the feeding

systems can be classified as comparatively unimportant. As it showed that the stable

(management, stable area, conception) was of important influence on the surveyed parameters,

the differences between the constructions of feeding stations for horses of present

systems are probably of less meaning.]

  Title The Behaviour of Stallions in a Semiferal Herd in Iceland: Time Budgets, Home Ranges, and Interactions Type Journal Article

  Abstract A permanent herd of Icelandic horses with four stallions and their harems was studied for a total of 316 hours in a large pasture (215 ha) in May 2007 in Iceland. Interactions between stallions of different harems and other aspects of the horses' behaviour were studied. One stallion and nine horses were introduced into the pasture prior to the study to examine the reactions of the resident stallions to a newcomer. The stallions spent significantly less time grazing than other horses and were more vigilant. Home ranges overlapped, but harems never mixed. The stallions prevented interactions between members of different harems indirectly by herding. Generally, interactions between resident stallions were nonviolent. However, encounters with the introduced stallion were more aggressive and more frequent than between the other stallions. Here, we show that four harems can share the same enclosure peacefully. The social network seems to keep aggression at a low level both within the harems and the herd as a whole. We encourage horse owners to consider the feasibility of keeping their horses in large groups because of low aggression and because such a strategy gives the young horses good opportunities to develop normally, both physically and socially.

  Abstract Introduction

Are horses doing well in their husbandries? For the first time the answer shall be given objectively by an integral on-farm welfare assessment system for horse husbandries. A current research project at the Technical University Munich evaluates indicators for well-being, pain and suffering in horses in order to develop a welfare assessment system (Baumgartner and Zeitler-Feicht 2013, 2014a, 2014b, 2015, Zeitler-Feicht et al. 2015). The research project is professionally supported by horse husbandry experts from academics, industries as well as leading organizations for horse owners and veterinarians.

The aim of the project is to develop a welfare assessment system for all horse husbandry systems which can be applied both for sport horses and for leisure horses. It is based on national animal welfare standards (BMELV 2009) and does take sustainability into consideration. Animal-based indicators are completed with resource-based indicators if necessary. It is stipulated that indicators are valid, reliable and feasible.

Welfare criteria were formulated for the two principles „good health“ and „behavioural demands“ (see figure 1 and 2). Each has to be represented by at least one indicator.

The principle „behavioural demands“ aims at the possibility for horses to practise species-specific behaviour. It is gathered to what extent the housing conditions allow the horses to live out and show species-specific behaviour. Furthermore in the present studies the frequency of selected behaviours including abnormal behaviour were collected in precise timeframes.

Potential indicators for assessing equine welfare on-farm were selected by study of literature and field tests. The field tests included direct observations on free-ranged horses, horses in group-housing systems and single-stabled horses. The following section presents selected indicators that are feasible for assessing equine behaviour on-farm.

Feasible behavioural indicators for well-being

The literature research revealed that „being together“ is linked with affiliative behaviour. It includes „resting together“, „foraging together“ and additionally „walking together“. Horses do have a strong need for social bonds. „Being-together“ amongst horses must be voluntary and not caused by bad weather conditions or lack of space. Therefore the context must be considered. For temporary direct observations the frequency in group-housing systems is sufficient (0.57 ± 0.67 per horse per 20 minutes). That´s why in our study „being-together“ is considered as a feasible indicator for well-being for horses in permanent or temporary groups. It is intended to conduct further studies on its validity.

Other behaviours such as „social play“ is not only linked with positive emotional states in adult horses. Several studies showed that horses use „social play“ as a stress relief. However, it is too seldom to collect in an on-farm assessment system. Because of the lack of feasibility and validity we excluded „social play“ as an indicator for well-being.

Feasible behavioural indicators for suffering

Horses show „abnormal behaviour“ in distress, frustration, deprivation or conflict situations. The present studies showed a relatively high frequency in single-stabled horses (3.3 ± 6.45 per horse per 20 minutes). Hence „abnormal behaviour“ is a feasible and valid indicator for suffering. However, established stereotypes need to be excluded, because they may indicate a previous welfare status rather than the current welfare status.

Horses use „agonistic behaviour“ to regulate social relations, to defend themselves or to defend resources. If husbandry or management is inadequate, „agonistic behaviour“ increases and thereby the frequency of injuries caused by social conflicts. A high frequency of „agonistic behaviour“ indicates a high aggression level in group-housed horses and therefore distress and suffering. The mean frequency of group-housed horses is sufficient for temporary observations (2.6 ± 2.26 per horse per 20 minutes). As a result „agonistic behaviour“ is a feasible and vaild indicator for suffering. Further studies need to be done on the scoring and severity.

  Title What eye wrinkles in horses tell us about their emotional state Type Conference Article

  Volume Issue Pages (up)

  Abstract Wrinkles above the eye ball are common in domestic horses but may differ in number and shape both between and within individuals. They are caused by contraction of the inner eye brow raiser, and some people working with horses call them “worry wrinkles”, considering them to reflect emotional states. However, as yet no study has formally investigated the relationship between eye wrinkles and emotional state in horses.

The aim of the present study was to induce states of different emotional valence and to assess whether positive emotional states would reduce the expression of eye wrinkles while negative emotional states would increase it. Sixteen horses were confronted in a balanced order with two presumably positively and two negatively valenced situations each. Positive situations included anticipation of a food reward (FA) and petting (P), negative situations included food competition (FC) and waving a plastic bag (PB). Each situation lasted for 60s (TRT) and was preceded by a 60s control phase (CON). Throughout CON and TRT pictures of the eyes were taken, and for each horse four pictures per situation (FA, P, FC, PB) and phase (CON and TRT) were randomly selected (n = 512) and scored in random order and blind to treatment for six outcome variables: overall impression (qualitative), number, angle and markedness of eye wrinkles, presence of eye white, and shape of eye lid.

Data were analysed separately for the right and left eye using linear mixed effects models (angle, number), generalised linear mixed models (eye white, markedness), and ordered logistic regression (qualitative, shape of eye lid), with “situation” (FA, P, FC, PB), “phase” (CON, TRT) and their two-way interaction as fixed effects.

Expression of eye wrinkles did not vary consistently across “situation” and “phase”. Independent of phase, eye white appeared less frequently during P than during FA (z=-3.15, p=0.009), FC (z=-2.94, p=0.02), and PB (z=4.17, p<0.001) in the left eye and during PB (z=4.10, p 0.001) in the right eye. Similarly, wrinkles were less marked during P compared to the other situations in the left eye (FA: z=3.15, p=0.009; FC: z=-2.94, p=0.017; PB: z=4.17, p<0.001) and compared to PB in the right eye (z=4.10, p=0.001), while no differences between situations occurred in number of wrinkles, overall impression and shape of eye lid for both eyes. Consistent with our hypothesis, P induced relaxation of the underlying muscle in the right eye resulting in a wider angle compared to its control phase (interaction situation*phase: F3,10=3.71, p=0.055; post-hoc comparison: z=-3.57, p=0.009), while FC induced muscle contraction, resulting in a sharper angle in the left eye (interaction situation*phase: F3,11=6.57, p=0.011; z=3.73, p=0.005).

We conclude that emotional valence may affect characteristics of eye winkle expression in horses which might therefore be a promising indicator of horses’ emotional states, but further research is needed to validate the relevant outcome variables.

  Title Sex, but not relatedness nor age, affect the social network of horses in a semi-natural reserve Type Conference Article
  Year 2015 Publication Proceedings of the 3. International Equine Science Meeting Abbreviated Journal Proc. 3. Int. Equine. Sci. Mtg

  Abstract For some time now, social network analysis provides tools to describe concisely the social structure of animals. Nevertheless, the factors that shape the social network and determine the frequency of different types of affiliations are often unclear. For example, the effects of relatedness on social networks have been only studied on relatively few species. Both among social or sub-social species the effects ranged from no effect to a substantial effect. Here we test the hypothesis that relatedness has an effect on the social network of horses (Equus caballus) that live freely in semi-natural conditions, and specifically, that individuals with high values of relatedness to their neighbors in the network will have fewer links Wolf et al, 2011). This hypothesis is based on the notion that related individuals have common interests and are likely to assist each other, and may need less links to other, unrelated individuals. In addition, individuals of similar age and sex are likely to have common needs, and thus are more likely to be associated. We thus tested a second hypothesis: homophily to individuals with similar age and sex will have a role in determining the associations within the social network. The field study was conducted on 27 horses in the Blauwe Kamer reserve in the Netherlands (1.1 sq km). We videotaped horses and their groups and used the information from 22 horses, after excluding the five foals from the analysis. Relatedness was calculated from the pedigree, which was based on parentage, determined by DNA analysis. The social network was constructed based on spatial proximity data. We assessed the influence of relatedness, age-homophily and sex-homophily on the network structure with Multiple Regression Quadratic Assignment Procedure (MRQAP) (Krackhardt 1988), with the R package sna. The results show that there was no significant effect of relatedness on the network, nor an effect of age-homophily. Nevertheless, we found a significant effect of sex-homophily, the tendency of individuals to associate with individuals of the same sex. We argue that the lack of a relatedness effect is not likely to have been caused due to the inability to detect who is kin. The structured social system in horses includes strong associations between often unrelated individuals, alongside with young individuals leaving their natal harem as part of the inherent inbreeding avoidance (Linklater & Cameron 2009; Boyd et al. in press). The significant effect of sex-homophily could stem from the protection females get from associations with other females, e.g., in the reduction of harassment from males. Previous studies on feral horses showed that mares that were better connected with other females in their harem benefited from higher survival rates to their foals (Cameron et al. 2009). The associations among bachelor males could also contribute to the strength of the sex-homophily effect.

In order to generalize from our results, one needs to examine additional populations of horses, because the conditions in the Blauwe Kamer reserve may not be representative, mainly due to the limited opportunity for dispersal in a restricted area.

  Title The impact of paddock design on the behaviour of the domestic horse (Equus caballus) Type Conference Article

  Abstract The design of a captive environment should facilitate the expression of the natural behavioural repertoire of the species concerned. The domestic horse (Equus caballus) is a social, herd dwelling species that is often housed in isolation from con-specifics or kept in groups in paddock enclosures. Although the latter allows for social interaction and does not restrict movement per se, it may not promote natural activity patterns or group cohesion. The aim of the current study was to assess the impact of two different paddock designs on the behaviour of a stable group of horses (n=6: 2 mares, 4 geldings).

The paddock designs tested were adjacent and grassed similarly, but configured differently. A central paddock (75 x 75m) designated NT, was surrounded by a track 1.6-5.5m wide, designated T. The horses were turned out in their group into T or NT for 3 consecutive days. Their behaviour was recorded for one hour three times each day (10.00, 13.00, 16.00 hrs). Within each observation period of one hour focal sampling was used, each individual horse being observed for a 10 minute period. They were then moved to the other enclosure type for a further 3 consecutive days, followed by a repeat of each condition. When turned out the horses were fitted with a global positioning system device (Garmin Forerunner 305) to monitor distance travelled and speed for the period 10.00-17.00 hrs. The mean percentage of time spent in each behavioural state (standing alert, standing resting, walk/trot, grazing, lying, social interaction) during the periods observed was calculated. Behaviour during social interactions was classified as either affiliative (approach, follow, friendly contacts, mutual grooming) or agonistic (approach and retreat, bite, chase, head threat).

The horses travelled significantly further in T than in NT (paired samples t-test: t (5) = 11.74, p<0.001) and moved significantly faster (Wilcoxon signed rank test: z = -2.21, p=0.03). See Table 1. When the percentage of time spent in each behavioural state in T and NT was compared some significant differences were found. A significantly higher percentage of time was spent active (walking /trotting) in T than in NT (paired samples t-test: t (5) = 5.74, p=0.002). Standing alert was only recorded in T (paired samples t-test: t (5) = 3.48, p=0.02). A significantly higher percentage of time was spent grazing in NT than in T (paired samples t-test: t (5) = -3.58, p=0.016). Significantly more social interaction occurred in T than in NT (paired samples t-test: t (5) = 5.93, p=0.002). See Figure 1. In T, 91% of social interactions were affiliative and 9% agonistic, whereas in NT 29% were affiliative and 71% agonistic. No difference was found in the percentage of time spent standing resting or lying down in T and NT.

The benefits of housing horses in groups as opposed to individually have been demonstrated in previous studies. In addition to better satisfying the behavioural needs of the horse it has been found that group housed horses adapt more easily to training and display less undesirable behaviour than those housed individually (Rivera et al. 2002; Søndergaard and Ladewig 2004; Visser et al. 2008). However, individual housing is frequently selected by horse owners in preference to group housing to avoid the risk of injury during agonistic encounters. Fureix et al. (2012) suggest that management practices may well contribute to aggressiveness in horses and that the conditions under which we keep horses should be reviewed. The findings of the present study indicate that the design of the enclosure in which groups of horses are kept affects the nature of social interactions. The T paddock design resulted in reduced intra-group aggression. However, this paddock design also reduced the time spent grazing and increased vigilant behaviour. Although the results demonstrate that a paddock system including tracks may facilitate group cohesion and more natural movement patterns, the long-term impact on behaviour and welfare requires further investigation.
