  Title Auswirkungen verschiedener Gruppengrößen auf Bewegungsaktivität, Body Condition Score, Liege- und Sozialverhalten bei Jungpferden Type Journal Article
  Year 2010 Publication Züchtungskunde Abbreviated Journal (down) Züchtungskunde  
  Volume 82 Issue 4 Pages 282–291  
  Keywords Liegen, Aktivität, Gruppenhaltung, Jungpferde, Sozialverhalten, Body Condition Score [Lying behaviour, activity behaviour, group housing, young horses, social behaviour, Body Condition Score]  
  Abstract Ziel der Untersuchung war es, herauszufinden, welche Auswirkungen eine Erhöhung der

Gruppengröße bei Jungpferden auf die Bewegungsaktivität, das Liege- und Sozialverhalten

und die Körperkondition hat. Hierfür wurden insgesamt 42 Pferde im Alter von ein

bis zwei Jahren in Laufstallhaltung in die Untersuchung einbezogen. Die Jungpferde aus

der Bewegungs- und Liegeverhaltensanalyse waren in zwei Kleingruppen (acht und

11 Tiere) und einer Großgruppe (23 Tiere) aufgestallt.

In der Bewegungsaktivität waren deutliche Unterschiede zu erkennen. Es ließ sich ein

positiver Einfluss einer höheren Tierzahl nachweisen, aber kein Einfluss des Alters. Beim

Ruheverhalten konnten höhere Liegezeiten und -frequenzen mit einer Zunahme der

Gruppengröße und eine Abnahme der Liegezeit mit zunehmendem Alter ermittelt werden.

Eine Störung des Liegeverhaltens durch Gruppengrößen, die nicht der natürlichen

Herdenstruktur des Pferdes entsprechen, wurde nicht nachgewiesen. Jedoch hatte die

Haltung der Jährlinge in der großen Gruppe einen Anstieg der repulsiven Verhaltensweisen

zur Konsequenz. Zudem zeigte die Bestimmung des Body Condition Scores

Unterschiede in der Körperkondition bei den Jährlingen der Groß- bzw. der Kleingruppe.

Einem Mangel an Bewegung, der für das Auftreten von Gliedmaßenerkrankungen und

Verhaltensstörungen verantwortlich gemacht wird, kann durch die Haltung von Jungpferden

in großen Gruppen entgegengewirkt werden.

[It is often discussed that the inactivity of horses causes diseases of their musculoskeletal system. Due to these problems the objective of the investigation was to quantify if the size of a group has an effect on the behaviour of young horses. Data from 42 horses in the age of one to two years have been involved in the investigation. The data of two small groups were compared with data of one big group with 23 horses. The movement and lying behaviour of 28 horses were measured with ALT pedometers. The social behaviour of 33 yearlings was documented by direct observation. The results show that the median of the movement time of horses in group A is 82 minutes per day. In group B this increases to a median of 101 and group C reaches the highest median of 149. In the case of lying time an increasing group size leads to a longer duration and a higher frequency of lying, whereas an increase in the age reduces the lying duration. International research studies have shown that keeping of horses in big group husbandry systems is not very common by the owners of horses. In contrast these investigations have shown that horse keeping in big groups has no negative influence on the social behaviour and the Body Condition Score of young horses.]

  Title Development, level and prospects of the german horse breeding Type Journal Article

  Abstract The economic impact of the horses of the Federal Republic of Germany has gone up, the statistic numerals verify obviously that Germany took pride of place in Europe in terms of numbers of riders as well as numbers of horses. Successes of German branded horses let their breeders reach the summit worldwide. The carefully agreed breeding programme connects practical cognitions with those of science and permits the leading breeding areas unobstructed space to set their own priorities. Globalisation and rised demand of customers forces breeding associations towards a far-reaching reorganisation because just large powerful institutions can meet these requirements. An end of this process, which scarcely has just begun, cannot yet be conceivable seen. – Eugen Ulmer KG, Stuttgart.

  Title Animal learning and memory: an integration of cognition and ecology Type Journal Article
  Year 2002 Publication Zoology Abbreviated Journal (down) Zoology  
  Volume 105 Issue 4 Pages 321-327  
  Keywords cognitive ecology; spatial learning and memory; adaptive specialisation  
  Abstract Summary A wonderfully lucid framework for the ways to understand animal behaviour is that represented by the four [`]whys' proposed by Tinbergen (1963). For much of the past three decades, however, these four avenues have been pursued more or less in parallel. Functional questions, for example, have been addressed by behavioural ecologists, mechanistic questions by psychologists and ethologists, ontogenetic questions by developmental biologists and neuroscientists and phylogenetic questions by evolutionary biologists. More recently, the value of integration between these differing views has become apparent. In this brief review, we concentrate especially on current attempts to integrate mechanistic and functional approaches. Most of our understanding of learning and memory in animals comes from the psychological literature, which tends to use only rats or pigeons, and more occasionally primates, as subjects. The underlying psychological assumption is of general processes that are similar across species and contexts rather than a range of specific abilities. However, this does not seem to be entirely true as several learned behaviours have been described that are specific to particular species or contexts. The first conspicuous exception to the generalist assumption was the demonstration of long delay taste aversion learning in rats (Garcia et al., 1955), in which it was shown that a stimulus need not be temporally contiguous with a response for the animal to make an association between food and illness. Subsequently, a number of other examples, such as imprinting and song learning in birds (e.g., Bolhuis and Honey, 1998; Catchpole and Slater, 1995; Horn, 1998), have been thoroughly researched. Even in these cases, however, it has been typical for only a few species to be studied (domestic chicks provide the [`]model' imprinting species and canaries and zebra finches the song learning [`]models'). As a result, a great deal is understood about the neural underpinnings and development of the behaviour, but substantially less is understood about interspecific variation and whether variation in behaviour is correlated with variation in neural processing (see review by Tramontin and Brenowitz, 2000 but see ten Cate and Vos, 1999).

  Title Behaviour of Bachelor Males of the Przewalski Horse (Equus ferus przewalskii) at the Reserve Askania Nova Type Journal Article
  Year 2009 Publication Der Zoologische Garten Abbreviated Journal (down) Zoologische Garten  
  Volume 78 Issue 5-6 Pages 282-299  
  Keywords Equid; Przewalski horse (Equus ferus przewalskii); Bachelor group; Social behaviour  
  Abstract The aim of this study was to investigate social relationships between Przewalski horses at a high density in a bachelor group housed in a 3.5-ha enclosure. The group consisted of 16 males aged 5 to 16. Behavioural data were collected during 18 days, total 216 h. Fifteen minute focal animal sampling was used; each horse was observed three times a day for a total of 45 min. The occurrence of 25 behaviours was recorded, and group spacing behaviour was studied using nearest neighbour recordings. The group divided into four subgroups; this supports earlier findings of bachelor groups (n>=10) dividing into two or more subgroups if they included several males aged >5 years. The total frequency of social interactions was 14.6±1.1 h-1. Although the density of the group in this study was higher than in other zoos, the males interacted agonistically only 3.6 h-1. The most frequently observed social behaviour categories were friendly interactions. This study shows possibilities to use some investigative behaviours (marking, flehmen, olfactory investigation, etc.) as indicators of social status of animals in a group.

  Title The mind through chick eyes: memory, cognition and anticipation Type Journal Article
  Year 2003 Publication Zoological Science Abbreviated Journal (down) Zoolog Sci  
  Volume 20 Issue 4 Pages 395-408  
  Keywords Animals; Birds/anatomy & histology/*physiology; Brain/anatomy & histology/cytology/physiology; Cognition/*physiology; Memory/*physiology; Perception/physiology  
  Abstract To understand the animal mind, we have to reconstruct how animals recognize the external world through their own eyes. For the reconstruction to be realistic, explanations must be made both in their proximate causes (brain mechanisms) as well as ultimate causes (evolutionary backgrounds). Here, we review recent advances in the behavioral, psychological, and system-neuroscience studies accomplished using the domestic chick as subjects. Diverse behavioral paradigms are compared (such as filial imprinting, sexual imprinting, one-trial passive avoidance learning, and reinforcement operant conditioning) in their behavioral characterizations (development, sensory and motor aspects of functions, fitness gains) and relevant brain mechanisms. We will stress that common brain regions are shared by these distinct paradigms, particularly those in the ventral telencephalic structures such as AIv (in the archistriatum) and LPO (in the medial striatum). Neuronal ensembles in these regions could code the chick's anticipation for forthcoming events, particularly the quality/quantity and the temporal proximity of rewards. Without the internal representation of the anticipated proximity in LPO, behavioral tolerance will be lost, and the chick makes impulsive choice for a less optimized option. Functional roles of these regions proved compatible with their anatomical counterparts in the mammalian brain, thus suggesting that the neural systems linking between the memorized past and the anticipated future have remained highly conservative through the evolution of the amniotic vertebrates during the last 300 million years. With the conservative nature in mind, research efforts should be oriented toward a unifying theory, which could explain behavioral deviations from optimized foraging, such as “naive curiosity,” “contra-freeloading,” “Concorde fallacy,” and “altruism.”
