Title | Positive interactions lead to lasting positive memories in horses, Equus caballus | Type | Journal Article | ||
Year | 2010 | Publication | Animal Behaviour | Abbreviated Journal | Anim. Behav. |
Volume | 79 | Issue | 4 | Pages | 869-875 |
Keywords | Equus caballus; horse; human–animal relationship; learning; memory; positive interaction; social cognition | ||||
Abstract | Social relationships are important in social species. These relationships, based on repeated interactions, define each partner's expectations during the following encounters. The creation of a relationship implies high social cognitive abilities which require that each partner is able to associate the positive or negative content of an interaction with a specific partner and to recall this association. In this study, we tested the effects of repeated interactions on the memory kept by 23 young horses about humans, after 6 and 8 months of separation. The association of a reward with a learning task in an interactional context induced positive reactions towards humans during training. It also increased contact and interest, not only just after training, but also several months later, despite no further interaction with humans. In addition, this ‘positive memory’ of humans extended to novel persons. Overall, positive reinforcement enhanced learning and memorization of the task itself. These findings suggest remarkable social cognitive abilities that can be transposed from intraspecific to interspecific social contexts. | ||||

Title | Automatic feeding systems for horses in group housing systems with regard to animal welfare. Part 1: Feeding stalls versus automatic feeding systems | Type | Journal Article | ||
Year | 2010 | Publication | Tierärztliche Praxis Großtiere | Abbreviated Journal | Tierärztl Prax |
Volume | 38 | Issue | G | Pages | 363-370 |

Abstract | Gegenstand und Ziel: Überprüfung der Tiergerechtheit von Abrufstationen für Kraftfutter und Heu in der Gruppenhaltung von Pferden anhand ethologischer und physiologischer Parameter im Vergleich zu konventionellen Fressständen. Material und Methoden: Die Verhaltensbeobachtungen fanden in 11 bzw. 10 Offenlaufställen mit Abrufstationen bzw. Fressständen statt. 270 Pferde wurden individuell unterschieden. Untersuchungsparameter waren: Drohverhalten mit und ohne Verletzungsrisiko, Meideverhalten, Verdrängung aus dem Fressstand sowie Herzfrequenz und Integumentverletzungen. In jedem Betrieb erfolgten kontinuierliche Direktbeobachtungen für je einen 24-Stunden-Tag (Tortenstückverfahren). Ergebnisse: Im Wartebereich der Abrufautomaten traten signifikant mehr Drohgesten ohne bzw. mit Verletzungsgefahr je Pferd und Tag (8,6 bzw. 3,0) auf als im Wartebereich der Fressstände (3,4 bzw. 0,9). Demgegenüber konnten die Pferde in Abrufstationen (1,4 Drohgesten je Pferd und Tag) ungestörter fressen als in Fressständen (3,2 Drohgesten je Pferd und Tag). Insgesamt betrachtet ergab sich jedoch bei beiden Fütterungssystemen eine geringe Anzahl an sozionegativen Interaktionen im Bereich der Futtereinrichtungen. Die Herzfrequenz lag im Warteareal im Durchschnitt im physiologischen Bereich (44,59 ± 11,73 Schläge/min). Integumentverletzungen im Zusammenhang mit dem Fütterungssystem traten nicht auf. Der wichtigste Einflussfaktor auf die Untersuchungskriterien war der Betrieb (Fläche, Konzeption, Management). Schlussfolgerung: Unter dem Aspekt der Tiergerechtheit hinsichtlich des Stress- und Verletzungsrisikos durch soziale Interaktionen eignen sich bei ordnungsgemäßer Gruppenhaltung mit fachgerechtem Management sowohl Fressstände als auch Abrufstationen für Pferde im Offenlaufstall. [Objective: A comparison with regard to animal welfare of feeding stalls and automatic feeding systems for hay and concentrates in group housing systems for horses using parameters of ethology and physiology. Material and method: The observations of animal behaviour took place in 10 stables with feeding stalls and in 11 stables with automatic feeding systems. The field around the feeding systems was divided into three areas with comparable dimensions (waiting area, exit area and inside of the feeding system). 270 horses were individually observed. Parameters of research comprised: threatening behaviour with and without risk of injury, avoiding behaviour, ”chasing away from the feeding place”, as well as heart rate and injuries of the integument. Every group of horses was continuously observed for 24 hours. This observation took place on four different days and comprised six sessions, each of 4 hours. Results: In the waiting area of the automatic systems there were significantly more threatening gestures with and without risk of injuries for each horse and day (8.6 and 3.0, respectively) than in the waiting area of the feeding stalls. In contrast, the horses could eat more relaxed in the automatic systems (1.4 threatening gestures for each horse and day) than in the feeding stalls (3.2 threatening gestures for each horse and day). All together the number of negative interactions in the feeding area of both feeding systems was relatively low. The heart rate was within the physiological range (44,59 ± 11,73 beats/min) in the waiting area. There were no injuries of the integument in correlation with the feeding systems. The most important factor of the observation criteria was the individual group housing system with its different dimension, conception and management. Conclusion: Under the aspect of animal welfare both feeding systems are suitable for horses with respect to the risk of stress and injuries by social interactions and under the condition of proper group housing with professional management.] |

Title | Close social associations in animals and humans: functions and mechanisms of friendship | Type | |||
Year | 2010 | Publication | Behaviour | Abbreviated Journal | |
Volume | 147 | Issue | 11 | Pages | 1379 |
Keywords | Both humans and group-living animals associate and behave affiliatively more with some individuals than others. Human friendship has long been acknowledged, and recently scientists studying animal behaviour have started using the term friendship for close social associates in animals. Yet, while biologists describe friends as social tools to enhance fitness, social scientists describe human friendship as unconditional. We investigate whether these different descriptions reflect true differences in human friendship and animal close social associations or are a by-product of different research approaches: namely social scientists focussing on proximate and biologists on ultimate explanations. We first stress the importance of similar measures to determine close social associations, thereafter examine their ultimate benefits and proximate motivations, and discuss the latest findings on the central-neural regulation of social bonds. We conclude that both human friendship and animal close social associations are ultimately beneficial. On the proximate level, motivations for friendship in humans and for close social associations in animals are not necessarily based on benefits and are often unconditional. Moreover, humans share with many animals a similar physiological basis of sociality. Therefore, biologists and social scientist describe the same phenomenon, and the use of the term friendship for animals seems justified. | ||||

Title | Effects of enrichment items on activity and social interactions in domestic horses (Equus caballus) | Type | Journal Article | ||
Year | 2011 | Publication | Applied Animal Behaviour Science | Abbreviated Journal | Appl. Anim. Behav. Sci. |
Volume | 129 | Issue | 2-4 | Pages | 100-110 |
Keywords | Horse; Activity; Behaviour; Item; Enrichment; Social interactions | ||||
Abstract | The aim of this study was to investigate the use of items intended to provide enrichment during turnout, both for individual and group kept horses in an attempt to reduce the amount of passive behaviours. The study was divided into two parts, where study 1 involved eight horses rotated through eight individual paddocks, each containing one of seven enrichment items and one paddock being kept without item, functioning as a control. The horses' item-directed behaviours; passive behaviours or other non-item related activities were scored using instantaneous sampling, every minute for 1 h at the beginning and the end of the turnout period. Study 2 involved six horse groups (3-6 horses) and the same scoring methods and ethogram as in study 1. The four items that the horses interacted the most with during study 1 (straw STRA, ball filled with concentrates CBALL, branches BRAN and scratching pole POLE) are investigated in study 2. In addition, the amount of social interactions was recorded. Both horses kept individually (P < 0.05) and in groups (P < 0.0001) performed significantly more item-directed behaviours towards edible items like STRA and CBALL than other objects. There was, however, no overall relation between the numbers of item-directed behaviours and the number of passive behaviours observed, indicating that the enrichment items did not alone reduce the amount of passive behaviours during turnout periods. Such a reduction was, however, only apparent when horses spent more time eating green leaves growing on the paddock surface (R = -0.97 study 1, R = -0.67 study 2, P < 0.0001). Access to STRA in group kept horses also seemed to reduce the amount of agonistic behaviours (P < 0.0001). In conclusion, if grass is not available in paddocks, the provision of roughage reduces the amount of passive behaviours in singly kept horses and it also reduces the risk of agonistic interactions between horses kept in group. | ||||

Title | Is the avoidance distance test for the assessment of animals' responsiveness to humans influenced by either the dominant or flightiest animal in the group? | Type | Journal Article | ||
Year | 2011 | Publication | Applied Animal Behaviour Science | Abbreviated Journal | Appl. Anim. Behav. Sci. |

Keywords | Cattle; Avoidance distance; Human-animal relationship (HAR); Dominance | ||||
Abstract | 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 animals during the avoidance distance test. Eighty-eight pregnant heifers comprised of four different genotypes were used (22 animals per genotype): Limousin × Holstein-Friesian, Limousin × Simmental, Charolais × Limousin, and Charolais × Simmental. Sixty of the 88 heifers were group housed (n = 5) into 12 pens with 3 pens per breed, while 28 heifers were singly housed (seven heifers per breed). A reactivity test was performed on days 10, 18, 25 and 30 post-housing on the singly housed heifers, and then on the group housed heifers, on the same days, to calculate a reactivity score. On days 33 and 37 flight and dominance tests, respectively, were performed to identify the flightiest and the dominant animal within each group. On day 41, an avoidance test, measuring both the avoidance distance towards a familiar and an unfamiliar human, was performed on all heifers. No difference (P > 0.05) in reactivity scores was found between the genotypes, between pens for the group housed heifers or between singly housed and group housed heifers (P = 0.28). The avoidance distance (AD) of singly (S) housed heifers towards a familiar (F) (ADSF) human was shorter (P < 0.001) than the avoidance distance of group (G) housed heifers towards an unfamiliar human (ADSU). The ADSF and ADGF were correlated with the ADSU and ADGU (R = 0.87 for singly housed heifers; R = 0.61 for group housed heifers, P < 0.001). For the singly housed heifers, no correlation was observed between reactivity score and ADSF (R = 0.36, P = 0.18), whereas the reactivity score and ADSU were correlated (R = 0.68, P = 0.004). For the group housed heifers no significant correlation was detected between the reactivity score and ADGF (R = 0.18, P = 0.22) or ADGU (R = −0.11, P = 0.39). No influence of the most dominant animal and the flightiest animals was found on the behaviour of the group in term of avoidance distance and reactivity (P > 0.05). It is concluded that the assessment of the fear of the animals towards humans using the avoidance test at the feed bunk may be useful for singly and group housed heifers and that the leaders of a group such as the flightiest animal or the dominant animal did not influence the avoidance distance test. | ||||

Title | Three-dimensional analysis of horse and human gaits in therapeutic riding | Type | Journal Article | ||
Year | 2011 | Publication | Applied Animal Behaviour Science | Abbreviated Journal | Appl. Anim. Behav. Sci. |
Volume | 135 | Issue | 4 | Pages | 271-276 |
Keywords | Equine-facilitated interventions; Horse gait; Human gait; Three-dimensional analysis; Horse riding | ||||
Abstract | Therapeutic horse riding or hippotherapy is used as an intervention for treating individuals with mental and physical disabilities. Equine-assisted interventions are based on the hypothesis that the movement of the horse's pelvis during horseback riding resembles human ambulation, and thus provides motor and sensory inputs similar to those received during human walking. However, this hypothesis has not been investigated quantitatively and qualitatively. This study aimed to verify the hypothesis by conducting a three-dimensional analysis of the horse's movements while walking and human ambulation. Using four sets of equipments, we analysed the acceleration patterns of walking in 50 healthy humans and 11 horses. In addition, we analysed the exercise intensity by comparing the heart rate, breathing rate, and blood pressure of 127 healthy individuals before and after walking and horse riding. The acceleration data series of the stride phase of horse walking were compared with those of human walking, and the frequencies (in Hz) were analysed by Fast Fourier transform. The acceleration curves of human walking overlapped with those of horse walking, with the frequency band of human walking corresponding with that of horse walking. Exercise intensity, as measured by the heart rate and breathing rate, was not significantly different between horse riding and human walking. The levels of diastolic blood pressure were slightly higher during horse riding than during walking, but were lower during both conditions compared with those in normal conditions (P < 0.01). The present study shows that, although not completely matched, the accelerations of the horse and human walking are comparable quantitatively and qualitatively. Horse riding at a walking gait could generate motor and sensory inputs similar to those produced by human walking, and thus could provide optimum benefits to persons with ambulatory difficulties. | ||||

Abstract | Horses are a highly social species living in complex social systems which should require them to memorise and generalise social experiences and distinguish between familiar and unfamiliar conspecifics. In the main part of my thesis I concentrated on the specific conflict situation of a horse being introduced into a new social group, and investigated its behaviour and stress level. Horses were either introduced (1) immediately, (2) after an observation period, or (3) together with an integration horse after an observation period. Additionally, in the second part of my thesis I arranged several experiments to elaborate additional aspects which could affect the behaviour of horses during introductions. In this study I could describe a simplified method for measuring stress through the analysis of faecal GCMs in horses. An enzyme immunoassay (EIA) for 11-oxoaetiocholanolone using 11-oxoaetiocholanolone-17-CMO: BSA (3?,11-oxo-A EIA) as antigen showed high amounts of immunoreactive substances. The new assay increases the accuracy of the test and lowers the expenses per sample; also storing of samples at room temperature after collection is less critical. This is a big advantage both in the field of wildlife management of equids and in the field of equestrian sports (chapter 1). Comparing the different introduction techniques, the introduction with an integration horse led to significantly less total interactions and lower levels of aggression than the introduction of single horses, both immediately and after several days of observing the new group. Additionally, by observing the behaviour of the horses during everyday sociality I could develop a formula describing the interrelationship between expected aggression level and enclosure size per horse. The curve takes an exponential shape. Starting from a space allowance of 300 m2 and more per horse, the amount of aggressions per hour approaches zero. For the reduction of aggression levels and injury risks in socially kept horses I recommend an enclosure size of at least 300 m2 per horse (chapter 2). I further investigated the stress level of the introduced animals. Horses which were immediately introduced did not show elevated faecal GCMs. In contrast, horses which were introduced after an observation period had slightly elevated values 2 and 3 days after the introduction. For horses introduced together with an integration horse faecal GCMs were significantly above the baseline value on the day of introduction and 1 day after it. These differences between introduction techniques indicate that the introduction event itself is not as stressful as previously assumed. Rather standing together with an integration horse and not being able to integrate immediately into the complete group elicits stress in horses (chapter 3). In the commentary of chapter 4 several studies are discussed which failed to demonstrate social learning in horses. It is argued that they did not consider important aspects which could have an influence, such as the dominance status or the social background of the horses (chapter 4). In chapter 5 a social feeding situation was investigated. The social rank as well as the position of conspecifics affected the feeding strategy of horses. Domestic horses used social cognition and strategic decision making in order to decide where to feed. When possible they tended to return to the same, continuously supplied feeding site and switched to an ?avoidance tendency? in the presence of dominant horses or when another horse was already feeding there (chapter 5). One possibility to recognize group members is through olfactory recognition. In chapter 6 it is shown that horses are able to distinguish their own from their conspecifics? faeces. In addition, they paid most attention to the faeces of those group members from which they received the highest amount of aggressive behaviour (chapter 6). Horses show cognitive abilities because they are able to use humans as local enhancement cues when searching for food, independently of their body posture or gaze consistency when the persons face them. Moreover, they seem to orientate on the attention of familiar persons more than of unfamiliar persons (chapter 7). Altogether, the results of this thesis provide further support for the view that horses show good conflict resolution strategies. They are perfectly able to deal with the conflict situation of being introduced to new group members, and the introduction event itself is not as stressful as previously assumed. It is rather suggested that standing together with an integration horse and not being able to integrate immediately into the complete group elicits stress in horses. All additional experimental set-ups could demonstrate that horses are well capable of social cognition. | ||||

Abstract | Ziel: Überprüfung der Tiergerechtheit von in der Bauweise unterschiedlichen Futterabrufstationen für Pferde in Gruppenhaltung anhand ethologischer und physiologischer Parameter. Material und Methoden: In 32 Offenlaufställen (452 Pferde) mit computergesteuerten Abrufstationen für Kraftfutter und Heu erfolgten kontinuierliche Direktbeobachtungen für je einen 24-Stunden-Tag (Tortenstückverfahren). Erfasst wurden: Aufenthaltsdauer, Besuchshäufigkeit, Droh- und Meideverhalten im Fütterungsbereich, Blockaden sowie Herzfrequenz und Integumentverletzungen. Ergebnisse: Eine Durchlaufstation reduzierte die Zahl der Auseinandersetzungen im Fütterungsbereich signifikant. Ansonsten erhöhten die für das fressende Pferd tiergerechten Varianten (Fressstand mit Eingangssperre, ohne Austreibehilfe) Besuchshäufigkeit und Aufenthaltsdauer und steigerten somit auch die Anzahl an Drohgesten je Tier und Tag. Insgesamt betrachtet kann jedoch die Anzahl an sozionegativen Interaktionen im Fütterungsbereich der Abrufstationen als relativ gering eingestuft werden. Die Herzfrequenz lag im Warteareal bei den meisten Pferden im physiologischen Bereich (45,1 ± 12,42 Schläge/min), erhöhte sich jedoch in der Abrufstation um ca. 20 Schläge/min. Einige Tiere zeigten möglicherweise stressbedingt kurzfristig auffallend hohe Werte (≥ 100 Schläge/ min). Integumentverletzungen im Zusammenhang mit dem Fütterungssystem traten nicht auf. Der wichtigste Einflussfaktor auf die Untersuchungskriterien war der Betrieb (Fläche, Konzeption, Management). Schlussfolgerung: Durchlaufstationen sind pferdegerechter als Rücklaufstationen. Nicht tiergerecht sind Stationen mit stromführender Austreibehilfe. Weitere bauliche Unterschiede der derzeitigen Futterabrufstationen dürften eher von untergeordneter Bedeutung sein, vor allem da Flächengebot und Konzeption der Offenstallanlage sowie das Management die überprüften Kriterien zur Tiergerechtheit maßgeblich beeinflussen. Untersuchungen zur Abklärung der Ursache für die vereinzelt aufgetretenen sehr hohen Herzfrequenzwerte sollten durchgeführt werden. Objective: Comparison with regard to animal welfare of different automatic feeding systems for hay and concentrate in group housing systems for horses using parameters of ethology and physiology. Material and methods: Parameters of research comprised: duration of stay, frequency of visit, threatening behaviour with and without risk of injury, and avoiding behaviour as well as heart rate and injuries of the integument. 452 horses were observed at the feeding area of 32 run-out-sheds. Every group of horses was continuously observed following the pie chart system for 24 hours. Results: The “walk-through” station significantly reduced the number of conflicts in the feeding area, whereas those systems which are appropriate for the feeding horses (feeding station with access barrier and without stimulation device by electric shock) led to a higher frequency of visits and a longer duration of stay resulting in more threatening gestures. However, the number of negative interactions in the feeding area of the feeding systems can all together be classified as relatively insignificant. The heart rate was within the physiological range (45.1 ± 12.42 beats/min) in the waiting area, but increased by approximately 20 beats/min on average within the feeding station. Some horses showed a very high heart rate (≥ 100 beats/min) while entering the feeding station, possibly stress-related. There were no injuries of the integument associated with the feeding systems. The most important factor of the observation criteria was the individual group housing system with its different dimensions, conception and management. Conclusion: “Walk-through” stations are better than ”walk-back” stations with regard to animal welfare. Likewise, automatic feeding stations with a current-carrying stimulation device are not supportive of good welfare. The other differences between the constructions of feeding stations of present systems are probably of less importance, particularly as it was shown that the stable (management, stable area, conception) had a significant influence on the surveyed parameters. Investigations to obtain information on the cause for the sporadic occurrence of very high heart rate values should be undertaken.] |

Abstract | Citizen science is a form of research collaboration involving members of the public in scientific research projects to address real-world problems. Often organized as a virtual collaboration, these projects are a type of open movement, with collective goals addressed through open participation in research tasks. Existing typologies of citizen science projects focus primarily on the structure of participation, paying little attention to the organizational and macrostructural properties that are important to designing and managing effective projects and technologies. By examining a variety of project characteristics, we identified five types-Action, Conservation, Investigation, Virtual, and Education- that differ in primary project goals and the importance of physical environment to participation. | ||||

In conclusion, if grass is not available in paddocks, the provision of roughage reduces the amount of passive behaviours in singly kept horses and it also reduces the risk of agonistic interactions between horses kept in group. | ||||
