Dominance and Leadership: Useful Concepts in Human–Horse Interactions?
| Contributor(s):: Elke Hartmann, Janne W. Christensen, Paul D. McGreevy
Dominance hierarchies in horses primarily influence priority access to limited resources of any kind, resulting in predictable contest outcomes that potentially minimize aggressive encounters and associated risk of injury. Levels of aggression in group-kept horses under domestic conditions have...

Dog People and Cat People Differ on Dominance-Related Traits
| Contributor(s):: Alba, Beatrice, Haslam, Nick
Many people identify themselves as being either a “cat person” or a “dog person” based on their preference for these domestic animals. The purpose of this study was to test the common belief that there are personality differences between these types. Previous research has found differences...
Mounting behaviour in finishing pigs: Stable individual differences are not due to dominance or stage of sexual development
| Contributor(s):: Hintze, Sara, Scott, Desiree, Turner, Simon, Meddle, Simone L., D’Eath, Richard B.
Every year around 100 million male piglets are castrated in the EU, usually without anaesthesia or post-operative analgesia. This surgical intervention is painful and stressful. Several main players within the pig industry have voluntarily agreed to end the practice of surgical pig castration in...
Effects of restraint with or without blinds at the feed barrier on feeding and agonistic behaviour in horned and hornless goats
| Contributor(s):: Hillmann, Edna, Hilfiker, Sandra, Keil, Nina Maria
The strict dominance hierarchy in goats bears the risk of low-ranking goats not getting adequate access to feed, especially for goats in small groups. The aim of our study was to test the effect of restraint in headlocks with and without blinds at the feed barrier on feeding and agonistic...
Is the avoidance distance test for the assessment of animals’ responsiveness to humans influenced by either the dominant or flightiest animal in the group?
| Contributor(s):: Mazurek, Mickael, McGee, Mark, Minchin, William, Crowe, Mark A., Earley, Bernadette
A previously described (Windschnurer et al., 2009) avoidance distance test was used to assess animals’ fear of humans in order to quantify the human–animal relationship (HAR). This study investigated the influence of the dominant and flightiest animals within a group on the responsiveness of...
Effect of mares’ dominance rank on suckling behaviour in the loose housed domestic horses
| Contributor(s):: Komárková, Martina, Bartošová, Jitka, Dubcová, Jana
Suckling is a main part of maternal investment in equids. The suckling period is crucial for adequate physical as well as psychical development of the foal. The rank of the mother and her aggressiveness could be factors responsible for later reproductive or social success of the foal. We...
A bio-behavioral study of chronic idiopathic colitis in the rhesus macaque (Macaca mulatta)
| Contributor(s):: Howell, Sue, White, Daniel, Ingram, Sonya, Jackson, Raven, Larin, Jorge, Morales, Pablo, Garcia, Ana Patricia, Hicks, Chassey, Hopper, Kelly, Wagner, Joseph
This study focused on the bio-social factors that influence chronic idiopathic colitis (CIC) disease in rhesus macaques (Macaca mulatta). A retrospective study of CIC included all colony animals between 2007 and 2009. A prospective study included 36 rhesus macaques treated for CIC in 2008 and...
Agonistic behaviour after mixing in pigs under commercial farm conditions
| Contributor(s):: Stukenborg, Andreas, Traulsen, Imke, Puppe, Birger, Presuhn, Ulrich, Krieter, Joachim
The aim of the study was to investigate agonistic behaviour of pigs after regrouping pigs under commercial sow farm conditions. The behavioural patterns were observed over a 48-h period, directly after weaning (PIG-28; n=647) and 40 days later (growing pigs, PIG-68; n=224). Agonistic interactions...
Relationships between feeding behaviour, activity, dominance and feed efficiency in finishing beef steers
| Contributor(s):: Haskell, Marie J., Rooke, John A., Roehe, Rainer, Turner, Simon P., Hyslop, James J., Waterhouse, Anthony, Duthie, Carol-Anne
To increase the profitability and sustainability of beef production systems, the use of animals with high feed efficiency is preferred. Efficient animals eat less than their peers for the same or better growth. This efficiency can be measured using feed conversion ratios (FCR) and residual feed...
Important role of dominance in allogrooming behaviour in beef cattle
| Contributor(s):: Šárová, Radka, Gutmann, Anke Kristina, Špinka, Marek, Stěhulová, Ilona, Winckler, Christoph
In domestic cattle, the relationship between dominance and allogrooming behaviour has been investigated in several studies. However, the results do not show a consistent pattern. The aim of this study was to investigate this relationship in a stable female beef cattle herd using social network...
Temporal development of agonistic interactions as well as dominance indices and centrality parameters in pigs after mixing
| Contributor(s):: Büttner, Kathrin, Czycholl, Irena, Mees, Katharina, Krieter, Joachim
Previous studies showed that depending on different factors, such as age, level of familiarity or group size, the number of agonistic interactions in pigs directly after mixing can demonstrate a large variation: from groups which reveal a clear decline in agonistic interactions one day after...
Hierarchical status and body traits and reproductive characteristics of male pampas deer (Ozotoceros bezoarticus) maintained in all-male groups
| Contributor(s):: Villagrán, Matías, Beracochea, Florencia, Bartoš, Luděk, Ungerfeld, Rodolfo
An animal's social environment can influence individual physiological and reproductive status, which might have implications for the success of ex situ conservation programs. This study investigated the relationship between an individual's position in the social hierarchy, body and antler size,...
Leadership linked to group composition in Highland cattle (Bos taurus): Implications for livestock management
| Contributor(s):: Sueur, Cédric, Kuntz, Cédric, Debergue, Elise, Keller, Blandine, Robic, Florian, Siegwalt-Baudin, Flora, Richer, Camille, Ramos, Amandine, Pelé, Marie
Animals kept for livestock or conservation form strong cohesive groups when foraging and moving, in the same way as their wild counterparts. Collective decision-making involves making compromises by consensus to maintain group cohesion and synchronisation. This type of consensus can be observed...
