  Title Einflussfaktoren auf das Grooming-Verhalten bei wilden und verwilderten Pferden [Influencing factors on grooming behaviour in wild living horses] Type Book Chapter

  Abstract Die soziale Fellpflege wurde bei Equiden intensiv erforscht. Es stellte sich heraus, dass diverse Faktoren das Grooming-Verhalten beeinflussen können. Neben saisonalen Gegebenheiten sind dies vor allem soziale Faktoren, wie das Alter und Geschlecht der Tiere, die Hierarchie und Gruppenzusammensetzung sowie die Verwandtschaftsverhältnisse der Tiere untereinander. Diese Faktoren können sowohl bei der Häufigkeit der sozialen Fellpflege, als auch bei der Wahl des Partners eine entscheidende Rolle spielen. Zudem konnte gezeigt werden, dass auch das Aggressivitätslevel in einer Gruppe Einfluss auf das soziale Verhalten und die soziale Fellpflege nehmen kann. Inwiefern zwei Individuen, die sich häufig groomen, auch bevorzugt beieinander stehen, konnte bislang noch nicht eindeutig gezeigt werden, da es hierzu diverse Studien mit konträren Ergebnisse gibt. Dieser Aspekt sollte zukünftig dringend untersucht werden, da die beiden Datensätze häufig gemeinsam verwendet werden, um soziale Bindungen zu berechnen, ohne dass bislang ein eindeutiger Zusammenhang zwischen ihnen ermittelt werden konnte.

[Summary

Social grooming has been investigated intensively in Equids during the last years and several factors are known to influence the grooming behaviour. Beside seasonal conditions these are especially social factors as age and sex, hierarchy and group composition as well as kinship. These factors can affect the grooming frequencies and influence the choice of the grooming partner. Moreover, it could be demonstrated that the groups’

aggression level can influence the social behaviour and the grooming intensity. If individuals which show an increased grooming frequency often stand in close proximity as well, has not been affirmed, as, so far, no distinct correlation has been demonstrated. This aspect has to be investigated urgently, as both data sets are often used in combination for calculating social bonds.]

  Title Non-invasive monitoring of stress hormones for welfare assessment in domestic and wild equids Type Conference Article
  Year 2015 Publication Proceedings of the 3. International Equine Science Meeting Abbreviated Journal Proc. 3. Int. Equine. Sci. Mtg  
  Volume (down) Issue Pages

  Abstract Stress responses play an important role in allowing animals to cope with challenges. Glucocorticoids, key elements in the neuroendocrine stress axis, are traditionally measured as a parameter for welfare assessment. As blood sample collection itself disturbs an animal, non-invasive or minimal invasive methods have gained importance for assessing stress. In horses saliva and faeces are most frequently used. Faecal samples offer the advantage that they can be collected easily and stress-free. In faecal samples circulating hormone levels are integrated over a certain period of time. As a consequence faecal glucocorticoid metabolites represent the cumulative secretion and they are less affected by short episodic fluctuations of hormone secretion.

However, in order to gain reliable information about an animal’s adrenocortical activity, certain criteria have to be met: Depending whether the impact of acute or chronic stressors is assessed, frequent sampling might be necessary whereas in other cases, single samples will suffice. Background knowledge regarding the metabolism and excretion of glucocorticoids is essential and a careful validation is obligatory. In addition, this presentation will address analytical issues regarding sample storage, extraction procedures, and immunoassays and various examples of a successful application in equids will be given. Applied properly, non-invasive techniques to monitor stress hormones are a useful tool for animal welfare assessment.

  Title Social Networks: Linking Form with Function in Equid Societies Type Conference Article

  Volume (down) Issue Pages

  Abstract Animal societies develop from interactions and relationships that occur among individuals within populations. The fundamental tenet of behavioral ecology is that ecological factors shape behavior and determine the distribution and associations of individuals on landscapes. As a result, different social systems emerge in different habitats and under different environmental conditions. Since characterizing social systems depends on time and motion studies of individual actions and interactions that are often bilateral, such characterizations are often coarse-grained. If social relationships can be characterized using social networks, however, seemingly similar social organizations often reveal informative differences in terms of deep structure. Thus social network theory should be able to provide insights in to the connections between social form and function. This talk will explore how the network structures of horses, zebras and asses can provide novel insights into the functioning of animal societies with respect to the spread of memes, genes and diseases.

  Title Effects of season, age, sex and housing on salivary cortisol concentrations in horses Type Journal Article
  Year 2015 Publication Domestic Animal Endocrinology Abbreviated Journal Domest. Anim. Endocrinol.  
  Volume (down) Issue Pages  
  Keywords horse; cortisol; diurnal rhythm; reproduction; housing  
  Abstract Abstract Analysis of salivary cortisol is increasingly used to assess stress responses in horses. Since spontaneous or experimentally induced increases in cortisol concentrations are often relatively small for stress studies proper controls are needed. This requires an understanding of factors affecting salivary cortisol over longer times. In this study, we have analysed salivary cortisol concentration over 6 mo in horses (n = 94) differing in age, sex, reproductive state and housing. Salivary cortisol followed a diurnal rhythm with highest concentrations in the morning and a decrease throughout the day (P < 0.001). This rhythm was disrupted in individual groups on individual days; however, alterations remained within the range of diurnal changes. Comparison between months showed highest cortisol concentrations in December (P < 0.001). Cortisol concentrations increased in breeding stallions during the breeding season (P < 0.001). No differences in salivary cortisol concentrations between non-pregnant mares with and without a corpus luteum existed. In stallions, mean daily salivary cortisol and plasma testosterone concentration were weakly correlated (r = 0.251, P < 0.01). No differences in salivary cortisol between female and male young horses and no consistent differences between horses of different age existed. Group housing and individual stabling did not affect salivary cortisol. In conclusion, salivary cortisol concentrations in horses follow a diurnal rhythm and are increased in active breeding sires. Time of the day and reproductive state of the horses are thus important for experiments that include analysis of cortisol in saliva.

  Title Dominance rank is associated with body condition in outdoor-living domestic horses (Equus caballus) Type Journal Article
  Year 2015 Publication Applied Animal Behaviour Science Abbreviated Journal  
  Volume (down) Issue Pages  
  Keywords Equine; fatness; obesity; social behaviour; displacement  
  Abstract Abstract The aim of our study was to explore the association between dominance rank and body condition in outdoor group-living domestic horses, Equus caballus. Social interactions were recorded using a video camera during a feeding test, applied to 203 horses in 42 herds. Dominance rank was assigned to 194 individuals. The outcome variable body condition score (BCS) was recorded using a 9-point scale. The variables age and height were recorded and considered as potential confounders or effect modifiers. Results were analysed using multivariable linear and logistic regression techniques, controlling for herd group as a random effect. More dominant (p = 0.001) individuals generally had a higher body condition score (p = 0.001) and this association was entirely independent of age and height. In addition, a greater proportion of dominant individuals fell into the obese category (BCS >= 7/9, p = 0.005). There were more displacement encounters and a greater level of interactivity in herds that had less variation in age and height, lending strength to the hypothesis that phenotypic variation may aid cohesion in group-living species. In addition there was a strong quadratic relationship between age and dominance rank (p < 0.001), where middle-aged individuals were most likely to be dominant. These results are the first to link behavioural predictors to body condition and obesity status in horses and should prompt the future consideration of behavioural and social factors when evaluating clinical disease risk in group-living animals.
