| Abstract | The influence of recipient mares in commercial embryo transfer (ET) programs on behavior of the ET foals is a matter of great interest and controversial discussion. Presently, no interdisciplinary ethological and reproductive studies on this topic exist. However, empirical experience suggests that behavioral traits of the recipient mare do not influence those of the foal, thus implying a predominantly genetic origin of a horse“s basic character. Aim: The aim of the present study was to investigate the influence of recipient mares on behavioural traits of their ET products. Materials and Methods: Based on records of the embryo transfer program in Warmblood horses since 1990 at the Swiss National Stud, questionnaires concerning behavior, stereotypies and mother-foal-relationship were designed and completed by telephone interview: 18 scientifically assessed questions provided the basis for a linear description (Equine Personality Assessment Questionnaire, Lloyd et al., 2007). They were grouped in a) emotivity, b) social motivation, c) general level of activity, d) stress behavior, e) learning capacity and f) reactions towards humans. Questionnaires were designed for the owners of the ET offspring (minimum of three years of age), the sires, donor mares and the recipient mares. Out of 200 questionnaires, 25 complete ET families have emerged so far and were analysed. All genetic parents were Warmblood horses, as were 23 of the recipient mares, the other two were Franches-Montagnes horses. Results: Comparing the mean values of the four groups (genetic dam and sire, recipient mare and ET product), significant differences were found for the parameters emotivity (sires lower, p<0.001), learning behaviour (recipient mares lower, p<0.05) and activity (recipient mares lower, p<0.05). With only one exception, the multiple variable regression analysis found no significant influence of the recipient mare on the ET product. The only significant effect observed, was that of the social motivation of the recipient mare on the learning capacity of the ET offspring (r2= -0.421, p<0.05). In contrast, numerous significant effects of behavioural traits of the genetic dams and sires on their ET offspring (10 and 8, respectively) were observed. Conclusions: These preliminary results confirm field observations that the influence of the recipient mare does not play an important role in character development of the ET offspring. However, the investigated parameters indicate that the behavioural traits of the genetic parents appear to have a strong influence on the offspring”s behaviour.. This study model promises new achievements in the evaluation of genetic and environmental effects on the behavior of a horse.

| Title | Stressbelastung und Verhalten von Pferden in stromführenden gegenüber nicht stromführenden Führanlagen | Type | Journal Article | ||

| Abstract | Um die Stressbelastung von Pferden in Führanlagen zu vergleichen, wurden 12 Pferde während 3 Wochen in einer Führanlage mit und ohne stromführenden (3.7 kV) Abtrennungen bewegt. Zur Ermittlung der Stressbelastung wurden die Cortisolwerte im Blut gemessen, die Herzschlagfrequenz mittels Polar® registriert und das Verhalten erfasst. Weder die Cortisol- noch die Herzfrequenzmessungen zeigten einen bedeutenden signifikanten Unterschied zwischen Pferden, die in einer stromführenden beziehungsweise nicht stromführenden Führanlage gingen. Die höchsten Cortisol- und Herzfrequenzwerte wurden in der ersten Woche (Angewöhnungsphase) verzeichnet. Signifikante Unterschiede wurden bei den Verhaltensparametern «Spontanes Wechseln des Abteils» und «Kontakt mit der Trennwand» beobachtet: Während solche vor allem in der ersten Woche und vor dem ersten Stromeinsatz vorkamen, zeigte kein Pferd einen Abteilwechsel während und nach dem Stromeinsatz. Die Resultate dieser Studie deuten darauf hin, dass der Einsatz von stromführenden Abtrennungen in Führanlagen für Pferde keinen bedeutenden messbaren Stress verursacht. | ||||

| Abstract | A study carried out on 49 horses showed that it is possible to measure the attention time by operant conditioning. After teaching horses an instrumental task using a signal, we were then able to test their attention time by asking them to prolong it increasingly while setting success and failure criteria. Two tests were performed 3 weeks apart. The 2nd test was feasible without relearning, a proof of memory, and was repeatable, a proof of consistency in the attention time. A significant difference was observed between the 3 age groups. Young horses often performed very well during the 1st test but their attention dropped in the 2nd test while older horses were more stable with respect to attention and even increased it slightly. The study shows that there are individual differences but it was not possible to prove a significant influence of breed, gender and paternal influence. Consequently, learning appears to be one of the most interesting approaches for evaluating the attention of horses and for observing their behaviour. | ||||
