  Title Horse signals: The sounds and scents of fury Type Journal Article
  Year 1992 Publication Evolutionary Ecology Abbreviated Journal Evol. Ecol.  
  Volume 6 Issue 3 Pages 254-260  
  Keywords ommunication – combat – fighting ability – individual identity – signals – information – assessment – displays  
  Abstract During contests animals typically exchange information about fighting ability. Among feral horses these signals involve olfactory or acoustical elements and each type can effectively terminate contests before physical contact becomes necessary. Dung transplant experiments show that for stallions, irrespective of rank, olfactory signals such as dung sniffing encode information about familiarity suggesting that such signals can be used as signatures. As such they can provide indirect information about fighting ability as long as opponents associate identity with past performance. Play-back experiments, however, show that vocalizations, such as squeals, directly provide information about status regardless of stallion familiarity. Sonographs reveal that squeals of dominants are longer than those of subordinates and that only those of dominants have at their onset high-frequency components.

  Title How reliable is temperament assessment in the domestic horse (Equus caballus)? Type Journal Article
  Year 2002 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 78 Issue 2-4 Pages 175-191  
  Keywords Temperament assessment; Behavioural tests; Horses; Active and passive copers; Factor analysis  
  Abstract Differences in behavioural characteristics between individuals of the same species are often described as being due to the temperament of the individuals. These differences can have enormous implications for welfare with some individuals apparently being able to adapt to environmental challenge more easily than others. Such differences have resulted in animals often being described as either `active' copers, which try to escape from or remove an aversive stimulus, or `passive' copers, which show no outward signs of a situation being aversive, thus, appearing to be unaffected. Tests previously developed to assess the temperament of animals have been criticised for several reasons. Behaviour is often recorded and categorised using methods that are not objective and tests are generally carried out once with no consideration of whether or not behavioural responses are consistent over time. This study takes these factors into account. The behaviour of 33 horses was recorded in three types of test--an arena test, response to a person and response to an object. In order to test whether or not responses were consistent over time, the tests were repeated three times with an average of 9 days between trials. Test results were validated using responses from questionnaires completed by the farm team leader. The data were analysed using an initial principal component analysis (PCA) and factor analysis. The horses were found to behave consistently over the three trials in their responses in the arena test. The responses to the person test and the object test were similar to each other; however, these responses were not consistent over trials. The behaviour in the arena test was unable to be used to make a prediction of behaviour in the person and object tests and vice versa. The responses shown by the horses did not enable them to be categorised as either active or passive copers. Behavioural responses in the tests were not predictive of the response to a startle test (water spray), nor could they be used to predict status or response to being reintroduced to the group after testing. There was no relationship between the responses in the tests and the ratings given by the farm team leader. It was concluded that horses vary widely in their responses to artificial behavioural tests, with only the responses to an open-field arena test being consistent over time, and therefore, the only type of test which can indicate some core factor of temperament.

  Title Assessing the human-animal relationship in farmed species: A critical review Type Journal Article
  Year 2006 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 101 Issue 3-4 Pages 185-242  
  Keywords Human-animal relationships; Farm animals; Tests; Assessment; Welfare  
  Abstract The present paper focuses on six main issues. First, we briefly explain why an increased understanding of the human-animal relationship (HAR) is an essential component of any strategy intended to improve the welfare of farmed animals and their stockpersons. Second, we list the main internal and external factors that can influence the nature of the relationship and the interactions between human beings and farm animals. Third, we argue that the numerous tests that have been used to assess the HAR fall into three main categories (stationary human, moving human, handling/restraint), according to the degree of human involvement. Fourth, the requirements that any test of HAR must fulfil before it can be considered effective, and the ways in which the tests can be validated are discussed. Fifth, the various types of test procedures that have been used to assess the HAR in a range of farmed species are reviewed and critically discussed. Finally, some research perspectives that merit further attention are shown. The present review embraces a range of farmed animals. Our primary reasons for including a particular species were: whether or not general interest has been expressed in its welfare and its relationship with humans, whether relevant literature was available, and whether it is farmed in at least some European countries. Therefore, we include large and small ruminants (cattle, sheep, goats), pigs, poultry (chickens), fur animals (foxes, mink) and horses. Although horses are primarily used for sport, leisure or therapy they are farmed as draught, food or breeding animals in many countries. Literature on the HAR in other species was relatively scarce so they receive no further mention here.

  Title Public information for the assessment of quality: a widespread social phenomenon Type Journal Article
  Year 2002 Publication Philosophical Transactions of the Royal Society B: Biological Sciences Abbreviated Journal Phil. Trans. Biol. Sci.  
  Volume 357 Issue 1427 Pages 1549-1557  
  Keywords Breeding Patch Assessment Eavesdropping Fighting Mate Choice Copying Sociality Vicarious Sampling  
  Abstract We propose that the use of public information about the quality of environmental resources, obtained by monitoring the sampling behaviour of others, may be a widespread social phenomenon allowing individuals to make faster, more accurate assessments of their environment. To demonstrate this (i) we define public information and distinguish it from other kinds of social information; (ii) we review empirical work demonstrating the benefits and costs of using public information to estimate food patch quality; (iii) we examine recent work showing that individuals may also be using public information to improve their estimates of the quality of such disparate environmental parameters as breeding patches, opponents and mates; and finally (iv) we suggest avenues of future work to better understand the nature of public information use and when it might be used or ignored. Such work should lead to a more complete understanding of the behaviour of individuals in social aggregations.

  Title Horse personality: Variation between breeds Type Journal Article
  Year 2008 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 112 Issue 3-4 Pages 369-383  
  Keywords Horse personality; Breed; Assessment; Questionnaire survey; Animal  
  Abstract Anecdotal evidence from horse owners and handlers suggests the existence of breed typical behaviour and personality in horses. This is further supported by current research on heritability of personality characteristics in a range of species. The Horse Personality Questionnaire (HPQ) is a 25-item rating method that has previously been shown to be reliable for the assessment of personality in horses. Principal component analysis on HPQ data has identified six underlying personality components in horses. These are Dominance, Anxiousness, Excitability, Protection, Sociability and Inquisitiveness. Using the HPQ a survey of 1223 horses of eight different breeds was completed. Data were analysed to explore any differences in personality between breeds across the six personality components. Breed differences in personality were identified, and it was noted that variability between breeds varied between personality components. Anxiousness and Excitability showed the most variation between breeds, whilst Dominance and Protection showed the least variance. The results identified breed typical personalities that were comparable to results from previous studies as well as anecdotal evidence provided by the popular equine literature. The results are discussed in terms of the potential selection pressures that may have resulted in these differences.

  Title Relative importance of initial individual differences, agonistic experience, and assessment accuracy during hierarchy formation: a simulation study Type Journal Article
  Year 1997 Publication Behavioural Processes Abbreviated Journal Behav. Process.  
  Volume 41 Issue Pages 177-192  
  Keywords Dominance; Hierarchy formation; RHP; Agonistic experience; Assessment; Self-organization; Simulation  
  Abstract This simulation study explores some conditions leading to transitivity within dominance orders. Combinations of three parameters were varied to study their consequences upon hierarchy formation and upon the degree of linearity of resultant structures. The factors studied were: (1) the importance of initial resource holding potentials (RHPs); (2) changes brought in RHPs by successive victories and defeats; and (3) accuracy of RHP assessment made by opponents. Results show that initial differences in RHP always lead to perfectly transitive chains whose rank order reflects the importance of initial differences. Even when simulated animals make important errors while assessing each other during round robin tournaments, emerging dominance structures are perfectly linear and ranks obtained in the structure are highly correlated with initial values in RHPs. Moreover, accumulated experiences of victory and/or defeat alone always lead to perfectly linear hierarchies. Their combination with initial individual differences in RHP led to the same conclusion. Even when assessment was far from being perfect, not only perfect chains were formed but initial values in RHPs significantly influenced rank order when the contribution of victory and defeat to RHP was relatively unimportant. The higher the importance of victory and defeat to RHP as compared to that of initial RHP values, the lower was the correlation between initial RHP values and the ranks order reached by individuals in the resultant hierarchies. In general also, the lower the variation within initial RHPs, the lower was the correlation between initial RHPs and ranks in the hierarchy. At a given level of initial RHP dispersion, increasing the contribution of victory and defeat to RHP diminished the correlation between initial RHP values and obtained ranks. In addition, inaccurate assessment reduced the overall correlation, especially when dispersion of initial RHP values was low and the contribution of victory and defeat relatively unimportant. These results shed some light on the controversy about the respective roles of initial individual attributes and that of patterns of resolution in the formation of animal hierarchies. We present the emergence of social order within closed systems as those simulated here as a case of self-organization.

  Title Dominance in vertebrate broods and litters Type Journal Article
  Year 2006 Publication Quarterly Review of Biology Abbreviated Journal  
  Volume 81 Issue 1 Pages 3-32  
  Keywords Aggression; Assessment; Dominance; Individual recognition; Sibling conflict; Trained losing  
  Abstract Drawing on the concepts and theory of dominance in adult vertebrates, this article categorizes the relationships of dominance between infant siblings, identifies the behavioral mechanisms that give rise to those relationships, and proposes a model to explain their evolution. Dominance relationships in avian broods can be classified according to the agonistic roles of dominants and subordinates as “aggression-submission,” “aggression-resistance, ” “aggression-aggression,” “aggression-avoidance,” “rotating dominance,” and “flock dominance.” These relationships differ mainly in the submissiveness/pugnacity of subordinates, which is pivotal, and in the specificity/generality of the learning processes that underlie them. As in the dominance hierarchies of adult vertebrates, agonistic roles are engendered and maintained by several mechanisms, including differential fighting ability, assessment, trained winning and losing (especially in altricial species), learned individual relationships (especially in precocial species), site-specific learning, and probably group-level effects. An evolutionary framework in which the species-typical dominance relationship is determined by feeding mode, confinement, cost of subordination, and capacity for individual recognition, can be extended to mammalian litters and account for the aggression-submission and aggression-resistance observed in distinct populations of spotted hyenas and the “site-specific dominance” (teat ownership) of some pigs, felids, and hyraxes. Little is known about agonism in the litters of other mammals or broods of poikilotherms, but some species of fish and crocodilians have the potential for dominance among broodmates.

  Title Using the Five Domains Model to Assess the Adverse Impacts of Husbandry, Veterinary, and Equitation Interventions on Horse Welfare. Type Journal Article
  Year 2018 Publication Animals Abbreviated Journal Animals  
  Volume 8 Issue 3 Pages 41  
  Keywords horse; welfare assessment; equitation; husbandry; five domains  
  Abstract The aim of this study was to conduct a series of paper-based exercises in order to assess the negative (adverse) welfare impacts, if any, of common interventions on domestic horses across a broad range of different contexts of equine care and training. An international panel (with professional expertise in psychology, equitation science, veterinary science, education, welfare, equestrian coaching, advocacy, and community engagement; n = 16) met over a four-day period to define and assess these interventions, using an adaptation of the domain-based assessment model. The interventions were considered within 14 contexts: C1 Weaning; C2 Diet; C3 Housing; C4 Foundation training; C5 Ill-health and veterinary interventions (chiefly medical); C6 Ill-health and veterinary interventions (chiefly surgical); C7 Elective procedures; C8 Care procedures; C9 Restraint for management procedures; C10 Road transport; C11 Activity—competition; C12 Activity—work; C13 Activity—breeding females; and C14 Activity—breeding males. Scores on a 1–10 scale for Domain 5 (the mental domain) gathered during the workshop were compared with overall impact scores on a 1–10 scale assigned by the same panellists individually before the workshop. The most severe (median and interquartile range, IQR) impacts within each context were identified during the workshop as: C1 abrupt, individual weaning (10 IQR 1); C2 feeding 100% low-energy concentrate (8 IQR 2.5); C3 indoor tie stalls with no social contact (9 IQR 1.5); C4 both (i) dropping horse with ropes (9 IQR 0.5) and forced flexion (9 IQR 0.5); C5 long-term curative medical treatments (8 IQR 3); C6 major deep intracavity surgery (8.5 IQR 1); C7 castration without veterinary supervision (10 IQR 1); C8 both (i) tongue ties (8 IQR 2.5) and (ii) restrictive nosebands (8 IQR 2.5); C9 ear twitch (8 IQR 1); C10 both (i) individual transport (7.00 IQR 1.5) and group transport with unfamiliar companions (7 IQR 1.5); C11 both (i) jumps racing (8 IQR 2.5) and Western performance (8 IQR 1.5); C12 carriage and haulage work (6 IQR 1.5); C13 wet nurse during transition between foals (7.5 IQR 3.75); and C14 teaser horse (7 IQR 8). Associations between pre-workshop and workshop scores were high, but some rankings changed after workshop participation, particularly relating to breeding practices. Domain 1 had the weakest association with Domain 5. The current article discusses the use of the domain-based model in equine welfare assessment, and offers a series of assumptions within each context that future users of the same approach may make when assessing animal welfare under the categories reported here. It also discusses some limitations in the framework that was used to apply the model.

  Title Kosten-Nutzen-Analyse einer objektivierten Temperamentbeurteilung bei Pferden [Economic evaluation of an objective temperament assessment in horses] Type Journal Article
  Year 2013 Publication Züchtungskunde Abbreviated Journal  
  Volume 85 Issue 2 Pages 129-142  
  Keywords Kosten, Nutzen, Interieurbeurteilung, Pferd, Temperament [Economy, personality assessment, horse, temperament]  
  Abstract Das Ziel der vorliegenden Studie war die Ermittlung der Kosten eines Verhaltenstests zur

objektiven Temperamentbeurteilung. Sie wurde an 1028 Pferden auf 55 Zuchtveranstaltungen

und Privatbetrieben ermittelt.

Weiterhin wurde eine Befragung zur allgemeinen Akzeptanz einer solchen Beurteilung

bei Reitpferden durchgeführt. Zusätzlich wurde mit Hilfe einer Online-Umfrage die

Meinung zu den Kosten und dem Aufwand einer solchen Beurteilung ermittelt. Die

Kosten der Einführung einer objektiven Temperamentbeurteilung entsprechen nach Einbeziehung

aller Faktoren ca. 18 Euro je Pferd. Den Kosten steht die Zahlungsbereitschaft

für eine verbesserte, da objektivierte Temperamentbeurteilung gegenüber. Insgesamt

56,7% der Befragten wären bereit, mehr als 11 Euro für eine objektive Interieurbeurteilung

auf Leistungsprüfungen im Feld zu investieren. Im Rahmen von Stationsprüfungen

wären sie sogar bereit mehr als 30 Euro aufzuwenden. Die Wertsteigerung eines im

Rahmen des Verfahrens positiv bewerteten Pferdes um 5%, die von den Teilnehmern der

Umfrage durchschnittlich angenommen wird, würde zusätzlich den Gewinn beim Pferdeverkauf

steigern. Die Ergebnisse zeigen, dass die Kosten einer objektiven Temperamentbeurteilung

durch eine erhöhte Zahlungsbereitschaft der Käufer scheinbar kompensiert

werden können, so dass die Einführung eines Temperamenttests zur objektiven Interieurbeurteilung

in Form der vorgestellten Untersuchungen grundsätzlich finanzierbar ist.

[The aim of the present study was to assess costs as well as riders’ acceptance of an

objective temperament evaluation in riding horses. Costs were determined based on a

novel object test conducted in 1028 horses tested on 65 occasions during performance

tests or in private stables. In addition, an online survey was used to identify riders’

opinion about the costs and benefits of such an assessment. Based on the conditions

assumed in the present study the costs for temperament testing have amount 18 Euro per

horse. More than 50% of the respondents were willing to pay more than 11 Euro for an

objective temperament assessment in their horses during performance tests in field.

Within performance tests on station they would spend more than 30 Euro for an objective temperament assessment. Participants further assumed a rise in value of favourably

assessed horses by 5%, leading to increased profits when selling the horse. In conclusion,

riders appear to be willing to cover the additional costs accrued from the temperament

test. Therefore, the introduction of an objective temperament assessment is likely to pay

off.]
