Abstract: To establish a method for assessing equine temperament by use of a questionnaire, we carried out two surveys. The subject animals were all thoroughbreds maintained at the same farm. Respondents were the primary caretaker and two colleagues working with each horse. Factor analysis was performed on the responses to each survey. In both surveys, five factors were extracted and four of them were common between the two surveys. The common factors were [`]Anxiety', [`]Trainability', [`]Affability', and [`]Gate entrance'. There were sufficient internal consistencies in responses about [`]Anxiety', [`]Trainability', and [`]Affability' in the two surveys to indicate the validity of this questionnaire in evaluating these factors in equine temperament.

Stürmer, K. (2005). Untersuchungen zum Einfluss der Fütterung auf den Säure-Basen-Haushalt bei Ponys. Ph.D. thesis, , .
Abstract: In der praktischen Pferdefütterung kommen regelmäßig Substanzen zum Einsatz, die
einen erheblichen Einfluss auf den Säure-Basen-Haushalt ausüben. Andererseits können
Manipulationen des Säure-Basen-Haushaltes in der Diätetik erwünscht sein, z.B. bei
Harnsteinen oder hyperkaliämischer periodischer Paralyse. Verschiebungen im Säure-
Basen-Gleichgewicht treten – unabhängig von der Fütterung – außerdem bei starker
körperlicher Aktivität auf, eine eventuelle Prophylaxe durch die Ernährung wird
ebenfalls diskutiert. Der Einfluss der Fütterung auf den Säure-Basen-Haushalt ist beim
Pferd bisher nur wenig und nicht systematisch untersucht, während sich viele Arbeiten
mit dem Effekt körperlicher Belastung beschäftigen. Analogieschlüsse zu anderen
Spezies müssen äußerst vorsichtig betrachtet werden, da die Absorption von am Säure-
Basen-Haushalt beteiligten Substanzen beim Pferd Unterschiede zu anderen Spezies
aufweist (Meyer, 1982).
In der vorliegenden Untersuchung sollte daher der Effekt von verschiedenen Chloriden
(Natriumchlorid, Kalziumchlorid, Ammoniumchlorid) auf den Säure-Basen-Haushalt bei
Ponys geprüft werden. In den ersten Versuchsdurchgängen wurden für Kleinpferde im
Erhaltungsstoffwechsel für diesen Zweck Rationen mit sehr hohen Heuanteilen
verwendet. Trotz hoher Dosen des bei verschiedenen Spezies stark säuernden
Ammoniumchlorids traten bei den Ponys nur relativ kleine Effekte auf. Bei der weiteren
Durchsicht des Schrifttums fiel auf, dass Einzelbeobachtungen zu stark säuernden
Effekten nur bei Rationen mit hohem Anteil an Kraftfutter und geringem Anteil an
Rauhfutter auftraten. Daher wurde der Effekt von Ammoniumchlorid auf einer stark
kraftfutterhaltigen Ration nochmals überprüft.

Abstract: It is known that the right and left brain hemispheres differ in their ability to regulate autonomic processes in the organism. Direct unilateral stimulation of the brain provokes side-dependent endocrine, immune and other visceral reactions. Since brain hemispheres are mainly involved in the regulation of muscles and sensory organs on the contra lateral side of the body the activation of behavioural asymmetry stimulates the contra lateral half of the brain. The important theoretical and practical question of whether autonomic processes can be regulated via the behavioural asymmetry route remains unexplored. In this study, we report that the chronic presentation of an emotionally important stimulus--food--from the left side, improves reproductive performance in animals in a broad range of feeding conditions. The unilateral presentation of food can also influence lactation, but in this case the side-dependent effects are different under varying feeding conditions. This finding opens a simple practical approach to influence basic somatic functions in the organism.

Kilian, A., Fersen, L. von, & Güntürkün, O. (2005). Left hemispheric advantage for numerical abilities in the bottlenose dolphin. Behav. Process., 68(2), 179–184.
Abstract: In a two-choice discrimination paradigm, a bottlenose dolphin discriminated relational dimensions between visual numerosity stimuli under monocular viewing conditions. After prior binocular acquisition of the task, two monocular test series with different number stimuli were conducted. In accordance with recent studies on visual lateralization in the bottlenose dolphin, our results revealed an overall advantage of the right visual field. Due to the complete decussation of the optic nerve fibers, this suggests a specialization of the left hemisphere for analysing relational features between stimuli as required in tests for numerical abilities. These processes are typically right hemisphere-based in other mammals (including humans) and birds. The present data provide further evidence for a general right visual field advantage in bottlenose dolphins for visual information processing. It is thus assumed that dolphins possess a unique functional architecture of their cerebral asymmetries.

Abstract: We recorded preferential use of the left and right monocular visual field in black-winged stilts, Himantopus himantopus, during predatory pecking and during courtship and mating behaviour in a naturalistic setting. The stilts had a population-level preference for using their right monocular visual field before predatory pecking; pecks that followed right-hemifield detection were more likely to be successful than pecks that followed left-hemifield detection, as evinced by the occurrence of swallowing and shaking head movements after pecking. In contrast, shaking behaviour, a component of courtship displays, and copulatory attempts by males were more likely to occur when females were seen with the left monocular visual field. Asymmetric hemifield use observed in natural conditions raises interesting issues as to the costs and benefits of population-level behavioural lateralization in wild animals.

Güntürkün, O. (2005). How asymmetry in animals starts. European Review, 13(2), 105–118.
Abstract: This review aims to present a speculation about mechanisms that shape the brains of humans and other animals into an asymmetrical organization. To this end, I will proceed in two steps: first, I want to recapitulate evidence from various experiments that show that some but not all asymmetries of the avian brain result from a prehatch light stimulation asymmetry. This should make it clear that avian embryos have a genetic predisposition to turn their head to the right. This results in a higher level of prehatch light stimulation of their right eye. The concomitant left–right difference in sensory input alters the brain circuits of the animal for the entire lifespan in a lateralized way. In the second part of the paper I will present evidence that some of the asymmetries of the human brain take a similar ontogenetic path as those observed in birds. This review provides the evidence that critical ontogenetic processes discovered in animal models could also be involved in the ontogeny of human cerebral asymmetries.
