| Abstract | Equine welfare can be enhanced by applying species specific training. This may incorporate social learning, as horses are highly social and social stimuli are of primary importance. Social learning is comparable to individual learning in its learning mechanisms, differing primarily in the way it is stimulated. Our initial study showed that horses of different breeds (N = 38) follow humans after observing other horses doing so, but only if the observed horse was familiar to and higher ranking than the observer (Fisher's exact test: N = 12, P = 0.003). A second study showed that horses and ponies (N = 25) learned to pull a rope to open a feeding apparatus after observing demonstrations by conspecifics, again, only if the demonstrating horse was older and higher ranking than the observer (Fisher's combination test, N = 3, v2 = 27.71, p = 0.006). Our third approach showed that horses and ponies (N = 24) learned to press a switch to open a feeding apparatus after observing a familiar person (GzLM: N = 24, z = 2.33, P = 0.02). Most recently, we confronted horses and ponies (N = 50) with persons demonstrating different techniques for opening a feeding apparatus. In this study we investigated whether the horses would copy the demonstrators' techniques or apply their own. Here only some horses copied the technique, and most of the successful learners used their mouths irrespective of the demonstrators' postures (Chi Square Test: N = 40, df = 2, χ2 = 31.4, p < 0.001). In all the approaches social stimuli elicited learning processes in the test horses, while only a few individuals in the control groups mastered the tasks by individual learning. The following behaviour observed in the initial study may have been facilitated by a social stimuli (social facilitation), and the opening of the feed boxes in the subsequent studies appear to be mostly the result of enhancement (social enhancement). Some horses may have used the social stimuli at first and continued their learning process by individual trial and error. However, the horses were also selective in whom and some in how to copy. This may have been conditioned (socially conditioned) or the result of simple forms of reasoning on the reliability of the particular information provided by demonstrators of certain social ranks or social positions, as high ranking and familiar horses and familiar persons were copied and some imitated exactly. Lay person message: Traditional riding instructions suggest that horses learn by observing other horses. For example, older, more experienced driving horses are used for initial training of young driving horses. We have shown that horses indeed use learning stimuli provided by other horse, as well as by humans. Horses readily accept stimuli observed in high ranking and familiar horses, and familiar persons. Such stimuli elicit learning processes which are comparable to individual learning. We suggest applying social learning whenever possible, as it is much faster and less stressful than individual learning, where learners experience negative outcomes in trial and error learning. |

| Title | Fallstudie zum Platzangebot, Verhalten und Wohlbefinden der Pferde (Equus caballus) in Mehrraum-Außenlaufställen mit Aus-lauf und Bewegungsställen [A case study to space, behavior and well-being of horses (Equus caballus) in open stables and open active stables] | Type | Manuscript | ||

| Abstract | Verhaltensbeobachtungen erfolgten an 112 Pferden in Mehrraum-Außenlaufställen mit Auslauf und Bewegungsställen. Bei vermehrtem Platzangebot sinkt das agonistische Verhalten in Bewegungsställen außerhalb des Fressbereiches. Mit zunehmender Stallgröße (überdachte Fläche und Auslauf) steigt in beiden Haltungsverfahren das affiliative Verhalten während das agonistische Verhalten mit Verletzungsrisiko sinkt. Daher wird für beide Haltungsverfahren ein möglichst großzügiger Stall je Pferd empfohlen. Die beobachteten Erkrankungen der letzten zwölf Monate zeigen vermehrt Hautkrankheiten in den Mehrraum-Außenlaufställen mit Auslauf, wohingegen Hufgeschwüre in Bewegungsställen auftraten. Wird der Fütterungsaspekt in den Bewegungsställen betrachtet, so ist die Transponderfütterung in Kombination mit ad libitum Fütterung aufgrund des deutlich geringeren, agonistischen Verhaltens beim Fressen, der reinen Transponderfütterung vorzuziehen. Mehrraum-Außenlaufställe mit Auslauf haben den Vorteil der synchronen Nahrungsaufnahme. [The behaviour of 112 horses was observed in open stables and open active stables. Horses show less agonistic behaviour outside of the feeding area in open active stables as the space for each horse is augmented. Also the affiliative behaviour increases as a function of more space per horse while agonistic behaviour with a risk for injury decreases. These results are independent from the husbandry system. Due to this fact a stable with a larger area per horse is recommended. Diseases of the last twelve month were recorded and show skin diseases in open stables and abscesses in the hooves in open active stables. To consider the feeding in open active stables it was found that horses which were fed with hay controlled by transponders showed more agonistic behaviour in contrast to horses being fed using transponders but with access to hay ad libitum. Thus transponder feeding in combination with ad libitum feeding is recommended. Open stables have the advantage of synchronized feeding.] |

| Abstract | Basic Commercial Court in Ankara wanted a report from our department of forensic medicine about two injury cases due to animal vehicle collision. The reports should include the disability rate and the duration of unfunctionality. After the examination we prepared the reports. Both vehicle collisions happened due to free ranging horse crossing the motorway. Both cases had different types of injury due to trauma. Vehicle collision due to horse crossing the motorway is rarely met in Turkey. Our first case is a man that had upper extremity and facial injury. He uses prothesis due to ear amputation. He has a scar tissue on the right side of his face and left forearm. The other case is three-years-old boy that had cranial bone fracture and cranial hematoma. He has also hemiparesis of the right side of body. Both cases have neurologic sequels but they have no psychiatric sequels. In literature, animal vehicle collisions involve lots of animal species such as kangaroo, deer, camel and moose. Animal vehicle collision involving the horses is rarely met. Forensic medicine specialists should state the causal link between traumatic events and disabilities in order to help justice. Our aim to present the current two cases is investigation of injuries of animal related collision and makes forensic medicine specialists pay attention to the subject of preparing reports about such cases. |
