Leblanc, M. - A. (2013). The mind of the horse, An Introduction to Equine Cognition. Harvard, MA: Harvard University Press.
Abstract: Horses were first domesticated about 6,000 years ago on the vast Eurasian steppe extending from Mongolia to the Carpathian Mountains. Yet only in the last two decades have scientists begun to explore the specific mental capacities of these animals. Responding to a surge of interest in fields from ethology to comparative psychology and evolutionary biology, Michel-Antoine Leblanc presents an encyclopedic synthesis of scientific knowledge about equine behavior and cognition. The Mind of the Horse provides experts and enthusiasts alike with an up-to-date understanding of how horses perceive, think about, and adapt to their physical and social worlds.
Much of what we know—or think we know—about “the intelligence of the horse” derives from fragmentary reports and anecdotal evidence. Putting this accumulated wisdom to the test, Leblanc introduces readers to rigorous experimental investigations into how horses make sense of their world under varying conditions. He describes the anatomical and neurophysiological characteristics of the horse’s brain, and offers an evolutionary perspective by comparing these features with those of other species. A horseman himself, Leblanc also considers the opinions of renowned riding masters, as well as controversies surrounding the extraordinary powers of the horse’s mind that have stirred in equestrian and scientific circles.
Although scientists understand more today about how horses think than at any time in our species’ long acquaintance with these animals, much remains in the dark. The Mind of the Horse brings together the current state of equine research and will likely stimulate surprising new discoveries.

Graf, P., Schneider, T., KönigvonBorstel, U., & Gauly M. (2013). Kosten-Nutzen-Analyse einer objektivierten Temperamentbeurteilung bei Pferden [Economic evaluation of an objective temperament assessment in horses]. Züchtungskunde, 85(2), 129–142.
Abstract: Das Ziel der vorliegenden Studie war die Ermittlung der Kosten eines Verhaltenstests zur
objektiven Temperamentbeurteilung. Sie wurde an 1028 Pferden auf 55 Zuchtveranstaltungen
und Privatbetrieben ermittelt.
Weiterhin wurde eine Befragung zur allgemeinen Akzeptanz einer solchen Beurteilung
bei Reitpferden durchgeführt. Zusätzlich wurde mit Hilfe einer Online-Umfrage die
Meinung zu den Kosten und dem Aufwand einer solchen Beurteilung ermittelt. Die
Kosten der Einführung einer objektiven Temperamentbeurteilung entsprechen nach Einbeziehung
aller Faktoren ca. 18 Euro je Pferd. Den Kosten steht die Zahlungsbereitschaft
für eine verbesserte, da objektivierte Temperamentbeurteilung gegenüber. Insgesamt
56,7% der Befragten wären bereit, mehr als 11 Euro für eine objektive Interieurbeurteilung
auf Leistungsprüfungen im Feld zu investieren. Im Rahmen von Stationsprüfungen
wären sie sogar bereit mehr als 30 Euro aufzuwenden. Die Wertsteigerung eines im
Rahmen des Verfahrens positiv bewerteten Pferdes um 5%, die von den Teilnehmern der
Umfrage durchschnittlich angenommen wird, würde zusätzlich den Gewinn beim Pferdeverkauf
steigern. Die Ergebnisse zeigen, dass die Kosten einer objektiven Temperamentbeurteilung
durch eine erhöhte Zahlungsbereitschaft der Käufer scheinbar kompensiert
werden können, so dass die Einführung eines Temperamenttests zur objektiven Interieurbeurteilung
in Form der vorgestellten Untersuchungen grundsätzlich finanzierbar ist.
[The aim of the present study was to assess costs as well as riders’ acceptance of an
objective temperament evaluation in riding horses. Costs were determined based on a
novel object test conducted in 1028 horses tested on 65 occasions during performance
tests or in private stables. In addition, an online survey was used to identify riders’
opinion about the costs and benefits of such an assessment. Based on the conditions
assumed in the present study the costs for temperament testing have amount 18 Euro per
horse. More than 50% of the respondents were willing to pay more than 11 Euro for an
objective temperament assessment in their horses during performance tests in field.
Within performance tests on station they would spend more than 30 Euro for an objective temperament assessment. Participants further assumed a rise in value of favourably
assessed horses by 5%, leading to increased profits when selling the horse. In conclusion,
riders appear to be willing to cover the additional costs accrued from the temperament
test. Therefore, the introduction of an objective temperament assessment is likely to pay
off.]

Abstract: Faecal steroid hormone metabolites are becoming increasingly popular as parameters for reproductive functions and stress. The extraction of the steroids from the faecal matrix represents the initial step before quantification can be performed. The steroid metabolites present in the faecal matrix are of varying polarity and composition, so selection of a proper extraction procedure is essential. There have been some studies to address this complex but often neglected point. Radiolabelled steroids (e.g. cortisol or progesterone) have frequently been added to faecal samples to estimate the efficiency of the extraction procedures used. However, native, unmetabolized steroids are normally not present in the faeces and therefore the results are artifi- cial and do not accurately reflect the actual recoveries of the substances of interest. In this respect, recovery experiments based on faecal samples from radiometabolism studies are more informative. In these samples, the metabolite content accurately reflects the mixture of metabolites present in the given species. As a result, it is possible to evaluate different extraction methods for use with faecal samples. We present studies on sheep, horses, pigs, hares and dogs that utilized samples containing naturally metabolized, 14C-labelled steroids. We recommend extracting faecal steroids by simply suspending the faeces in a high percentage of a primary alcohol (for glucocorticoid metabolites 80% aqueous methanol proved best suited for virtually all mammalian species tested so far). Not only does the procedure significantly increase the total amount of recovered radioactivity, it also increases the percentage of unconjugated metabolites, which are more likely to be recognized by the antibodies used in various immunoassays. The advantages of this extraction procedure are clear: it is very easy to use (no evaporation step is needed), it yields high recoveries and variation based on the extraction procedure is reduced to a minimum.
