Abstract |
Innovative behaviour achieved through exploration, learning and insight heavily depends on certain motivational, social and ecological conditions of short duration. We propose that more attention should be given to what these conditions are and where they are realized in natural groups of non-human primates. Only to the extent that such favourable conditions were frequently realized in a social structure or an extraspecific environment could selective pressures act on innovative abilities. There is hope that research into field conditions of innovative behaviour will help to identify its selectors in evolution. |

Abstract |
Horses are often stabled in individual boxes, a method that does not meet their natural needs and may cause psychical and
musculoskeletal diseases. This problem is particularly evident in Iceland, where horses often spend the long winter periods in cramped
boxes. The aim of this study was to analyze the suitability of a group housing system in Iceland, but the results are also applicable to
horses of other regions. Eight Icelandic horses were observed in an active stable system, and their behavior and time budget were
recorded. Movement and lying behavior were studied with ALT (Activity, Lying, Temperature detection) pedometers. The effect of an
automatic concentrate feeding station (CFS) on the horses’ behavior was examined. In the first period of investigation, the horses
were fed concentrates manually, and in the second period, they were fed with the CFS. Additional behavioral observations and a
determination of social hierarchy occurred directly or by video surveillance. The physical condition of the horses was recorded by body
weight (BW) measurement and body condition scoring (BCS). The results showed a significant increase between the first and second
trial periods in both the activity (P,0.001) and the lying time (P50.003) of the horses with use of the CFS. However, there was no
significant change in BW during the first period without the CFS (P50.884) or during the second period with the CFS (P50.540).
The BCS of the horses was constant at a very good level during both trial periods, and the horses showed a low level of aggression, a
firm social hierarchy and behavioral synchronization. This study concludes that group housing according to the active stable principle is
a welfare-friendly option for keeping horses and is a suitable alternative to conventional individual boxes. |

Abstract |
Das Droh- und Meideverhalten von 270 Pferden wurde im Fressbereich von 10 Offenlaufställen
mit Fressständen und 11 Offenlaufställen mit computergesteuerten Abrufstationen
anhand von visuellen kontinuierlichen Direktbeobachtungen erfasst. Diese erfolgten je Betrieb
über einen 24-Stunden-Tag, der nach dem Tortenstückverfahren (6x4 Stunden) zusammengesetzt
war.
Insgesamt wurden 6297 agonistische Verhaltensweisen in, vor und hinter den
Fütterungseinrichtungen registriert (Meiden 40,6 %, Verdrängen 12,8 %, Beißen/ Hinterhandschlag/
Angehen 12,7 % und Drohen/ Drohbeißen/ Hinterhanddrohen 33,9 %). In den
Futterstationen wurden 22,5 % dieses Verhaltens beobachtet, vor und hinter den Futterstationen
77,5 %. Bei den Betrieben mit Fressständen fanden 31 % der agonistischen Verhaltensweisen
in den Ständen statt, bei den Betrieben mit Abruffütterung 21 %.
Der Einfl uss des einzelnen Betriebes (innerhalb Fütterungssystem) auf die agonistischen
Verhaltensweisen vor und hinter den Fütterungseinrichtungen war signifi kant. Die Auswertung
ergab, dass Drohgesten im Wartebereich von Abrufstationen häufi ger auftreten
als in dem von Fressständen. Demgegenüber können Pferde in Abrufstationen ungestörter
fressen. Insgesamt betrachtet war jedoch die Anzahl an sozionegativen Interaktionen im
Bereich der Futtereinrichtungen bei beiden Fütterungssystemen gering. Die agonistischen
Verhaltensweisen wurden zusätzlich noch von der Heumenge und dem Konstitutionstyp
beeinfl usst.
Der Betrieb erwies sich als maßgeblicher Einfl ussfaktor. Als Resümee ergibt sich, dass
bei ordnungsgemäßer Gruppenhaltung mit fachgerechtem Management beide Fütterungssysteme
für Pferde im Offenlaufstall geeignet sind.
[The threatening and avoiding behaviour of 270 horses living in run-out sheds was observed
at 10 stables with feeding stalls and at 11 stables with automatic feeding systems for hay
and concentrates. Every group of horses was observed on five succeeding days visually
and immediately for 6 sessions, each of 4 hours. These 6 slices form together 24 hours, a
complete day.
Altogether, 6297 agonistic behaviour patterns were registered in front of, inside and
behind the feeding stations (avoiding behaviour 40.6 %, edging out of others 12.8 %,
Auseinandersetzungen an automatischer Abruffütterung und Fressständen
KTBL-Schrift 471 79
biting/rear leg kicking/charging 12.7 % und threatening/biting threats/rear leg kicking
threats 33.9 %). 22.5 % of these types of behaviour were recorded in the feeding stations,
77.5 % together in front and behind of these. In the stables with feeding stalls there were
31 % of the observed threatening gestures inside the feeding stations, in the stables with
automatic feeders only 21 %.
The individual farm showed signifi cant infl uence on the modes of agonistic behaviour
in front and behind the feeding facilities. Threatening gestures happen more often in the
waiting area of automatic feeders than in that of feeding stalls. On the other hand horses
in computer controlled systems will be less disturbed at eating. All together the number
of negative interactions in the feeding area at both feeding systems was relatively low.
In addition the agonistic behaviour was infl uenced by the quantity of hay and the constitutional
typ of the horses.
Because of the management of the individual stable exercises the most substantial
infl uence on the behaviour of the horses, it can be said, that, correct group keeping with
professional management provided, both feeding systems are suitable for horses in run-in
sheds.] |

Abstract |
In 32 Offenlaufställen mit computergesteuerten Abrufstationen wurden die Aufenthaltsdauer
und Besuchshäufigkeit sowie das Droh- und Meideverhalten von 439 Pferden im
Füttererungsbereich erfasst. Je Betrieb erfolgten visuelle kontinuierliche Direktbeobachtungen
nach dem Tortenstückverfahren (6 x 4 Stunden) für je einen 24-Stunden-Tag.
Ziel war die Überprüfung der verschiedenen Bauausführungen der Abrufstationen unter
dem Aspekt der Tiergerechtheit. Eine Einwegstation reduzierte signifikant die Anzahl an Auseinandersetzungen
im Fütterungsbereich. Demgegenüber führten die für das fressende Pferd
tiergerechten Varianten (Fressstand mit Eingangssperre und ohne Austreibehilfe) zu einer
Erhöhung der Besuchshäufigkeit und Aufenthaltsdauer und somit auch zu einer erhöhten
Anzahl an Drohgesten. Doch insgesamt betrachtet, kann die Anzahl an sozionegativen
Interaktionen im Fütterungsbereich der Abrufstationen als relativ gering eingestuft werden.
Da sich außerdem der Betrieb (Management, Fläche, Konzeption) als maßgeblicher Einflussfaktor
auf die überprüften Parameter erwies, dürften die Unterschiede in der Bauausführung
der derzeitigen Abrufstationen für Pferde eher von untergeordneter Bedeutung sein.
[Duration of stay, frequency of visit, threatening gestures and behaviour of avoidance of
439 horses was observed at the feeding area of 32 run-out-sheds. The observation was based
on the method of visual continuously direct watching after the pie chart system (6 x 4 hours)
over a period of 24 hours. The observation should show which construction of the different
automatic feeding systems corresponded best under the aspect of animal welfare.
It was obvious that the one-way-station reduced significantly the number of conflicts
in the feeding area, whereas those systems which are appropriate for the eating horses
(feeding station with access barrier and without stimulation device by electric shock) led
to a higher frequency of visits and duration of stay as well as to more threatening gestures.
Considering altogether, the number of negative interactions in the feeding area of the feeding
systems can be classified as comparatively unimportant. As it showed that the stable
(management, stable area, conception) was of important influence on the surveyed parameters,
the differences between the constructions of feeding stations for horses of present
systems are probably of less meaning.] |

Abstract |
Abstract: Recent studies have reported an association between exposure to childhood abuse or neglect and alterations in brain structure or function. One limitation of these studies is that they are correlational and do not provide evidence of a cause–effect relationship. Preclinical studies on the effects of exposure to early life stress can demonstrate causality, and can enrich our understanding of the clinical research if we hypothesize that the consequences of early abuse are predominantly mediated through the induction of stress responses. Exposure to early abuse and early stress has each been associated with the emergence of epileptiform electroencephalogram (EEG) abnormalities, alterations in corpous callosum area, and reduced volume or synaptic density of the hippocampus.Further, there is evidence that different brain regions have unique periods when they are maximally sensitive to the effects of early stress. To date, preclinical studies have guided clinical investigations and will continue to provide important insight into studies on molecular mechanisms and gene–environment interactions. |

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. |

Abstract |
It can be a challenge to find a conventional saddle that is a good fit for both horse and rider. An increasing number of riders are purchasing treeless saddles because they are thought to fit a wider range of equine back shapes, but there is only limited research to support this theory. The objective of this study was to compare the total force and pressure distribution patterns on the horse’s back with conventional and treeless saddles. The experimental hypotheses were that the conventional saddle would distribute the force over a larger area with lower mean and maximal pressures than the treeless saddle. Eight horses were ridden by a single rider at sitting trot with conventional and treeless saddles. An electronic pressure mat measured total force, area of saddle contact, maximal pressure and area with mean pressure >11 kPa for 10 strides with each saddle. Univariate ANOVA (P < 0.05) was used to detect differences between saddles. Compared with the treeless saddle, the conventional saddle distributed the rider’s bodyweight over a larger area, had lower mean and maximal pressures and fewer sensors recording mean pressure >11 kPa. These findings suggested that the saddle tree was effective in distributing the weight of the saddle and rider over a larger area and in avoiding localized areas of force concentration. |

Abstract |
A permanent herd of Icelandic horses with four stallions and their harems was studied for a total of 316 hours in a large pasture (215 ha) in May 2007 in Iceland. Interactions between stallions of different harems and other aspects of the horses' behaviour were studied. One stallion and nine horses were introduced into the pasture prior to the study to examine the reactions of the resident stallions to a newcomer. The stallions spent significantly less time grazing than other horses and were more vigilant. Home ranges overlapped, but harems never mixed. The stallions prevented interactions between members of different harems indirectly by herding. Generally, interactions between resident stallions were nonviolent. However, encounters with the introduced stallion were more aggressive and more frequent than between the other stallions. Here, we show that four harems can share the same enclosure peacefully. The social network seems to keep aggression at a low level both within the harems and the herd as a whole. We encourage horse owners to consider the feasibility of keeping their horses in large groups because of low aggression and because such a strategy gives the young horses good opportunities to develop normally, both physically and socially. |
