| Abstract | Finding the right horse for each rider is a difficult task as it is just as important that the temperament of the horse fits the rider as it is that the horse is of the right size. Even though it is a commonly experienced problem, no objective method of easily measuring the horse“s temperament has yet been developed. If it is possible to test horses and get an objective measure of how reactive (emotional) they are, it could be a big help in finding the right horse for each rider. It would be desirable to have a way of testing the horse”s reaction in an unfamiliar (and potentially frightening) situation. In practice this test should be just as easy as it is getting a judgement of its conformation and gaits. The aim of the present study was to measure individual variation in HR response to different novel objects in horses of the same age, breed and reared in the same environment. We wanted to see whether certain horses (i.e. more emotional horses) react more to novel stimuli, in general, than other horses (i.e. less emotional), irrespective of the type of stimulus. We also wanted to see if different novel stimuli elicited different responses within individuals. The hypothesis was that individuals will react in a similar way to various stimuli. Twenty four Danish warmblood horses were included in this study. All horses were 2 year-old stallions, reared under similar environmental conditions. They had received a minimum of handling prior to the experimental period. Three different stimuli were used. They were chosen because they were novel to the horses and would elicit measurable fear-reactions in all horses, but not so much that the horses did not approach the feed within the duration of the test. The visual stimulus consisted of a 1meter high orange traffic cone with reflex stripes, placed 1 m in front of the tub, the olfactory stimulus was eucalyptus oil and the auditory stimulus was a radio tuned to white noise. The control was an empty arena. The result was that only the HR response to the auditory and visual stimuli differed significantly from the control days. The olfactory stimulus did not seem to alarm the horses the way the other stimuli did. We found a tendency towards a correlation in reaction between the olfactory and auditory stimuli and between the auditory and visual stimuli within individuals. These results indicate that horses do not generalize completely in their reaction between different stimuli. |

| Title | Is it possible to measure the welfare of the ridden horse? | Type |
Manuscript | ||

| Abstract | Since the time of domestication, humans have trained horses for the purpose of serving man. Different training methods have been developed throughout the centuries; some were developed with consideration for the horse's welfare, while others disregarded welfare to a great extent. Most present day training is based upon making the horse perform a desired behaviour through dominance and subordination. Although cooperative training techniques have gained popularity, everyday training lacks the application of learning theory or neglects the horse's learning capacities and their species' specific behaviour. Thus, the horse's welfare may be jeopardised. The aim with this review is to consider methods that allow an objective assessment of the welfare of horses undergoing training. The review gives a brief insight into the history of horse training and handling. It proceeds with an overview of the horse"s learning abilities which is argued to be of paramount importance for effective training. The review then describes a few selected training techniques that are used today, based on negative and positive reinforcement, and discusses parameters from which it could be possible to assess the welfare of the ridden horse. The work concludes with suggestion for future |

| Title | Is social learning correlated with innovation in birds? An inter-and an interspecific test | Type |

| Abstract | This thesis focuses on the relationship between innovation and social learning in the foraging context, across and within bird species, using two different sources of data: anecdotal reports from the literature, and experimental tests in the laboratory and the field. In chapter 1, I review the trends in innovation and social learning in the avian literature, and contrast them with trends in mammals, especially primates. In chapter 2, I use anecdotal reports of feeding innovation and social learning in the literature to assess taxonomic trends and to study the relationship between the two traits at the interspecific level. In chapter 3, I investigate the relationship between innovation and social learning at the intraspecific level in captive feral pigeons (Columba livia). Innovation is estimated from the ability to solve an innovative foraging problem, and social learning is measured as the number of trials required to learn a foraging task from a proficient demonstrator.

| Title | Einfluss reduzierter Futterzuteilung zweier verschiedener Heuqualitäten auf Passagedauer und Verdaulichkeit bei Ponies | Type |
Manuscript | ||
| Year | 2006 | Publication | Abbreviated Journal | ||
| Volume | Issue | Pages | |||
| Keywords | |||||
| Abstract | Über die Auswirkungen der Futtermenge und der Futterqualität auf die scheinbare Verdaulichkeit und die mittlere Retentionszeit beim Pferd gibt es zahlreiche Arbeiten mit zum Teil recht widersprüchlichen Ergebnissen. So existiert eine Hypothese, wonach bei geringerer Energiedichte im Futter die TS-Aufnahme steigt und die mittlere Retentionszeit abnimmt. Dadurch soll bei Equiden eine ausreichende Energieaufnahme trotz geringer Energiedichte im Futter erreicht werden (JANIS 1976, DUNCAN et al.1990). In nahezu allen Studien zu diesem Thema wurden Futter mit unterschiedlichem Nährstoffgehalt bei konstanter Futteraufnahme bzw. ad libitum Fütterung untersucht. Nur bei PEARSON et al. (2001 und 2006) findet sich für jedes Futter ein Vergleich von zwei verschiedenen Futtermengen, nämlich ad libitum und 70% der ad libitum Futteraufnahme. Systematische Untersuchungen bei Pferden zu Futtermengen, die unterhalb des Erhaltungsbedarfes liegen, fehlen bisher. In der vorliegenden Arbeit sollen deshalb im Wesentlichen drei Fragen geklärt werden: · Gibt es einen Einfluss von Futtermengen unterhalb des Erhaltungsbedarfes auf die mittlere Retentionszeit? · Haben Veränderungen der mittleren Retentionszeit einen Einfluss auf die scheinbare Verdaulichkeit? · Wie unterscheiden sich diese Effekte in Abhängigkeit von der Futterzusammensetzung? Die Ergebnisse dieser Studie sollen vor allem bezüglich ihrer Auswirkungen auf die praktische Pferdefütterung betrachtet werden. |

| Title | Untersuchungen zum Einfluss der Fütterung auf den Säure-Basen-Haushalt bei Ponys | Type |
Manuscript | ||
| Year | 2005 | Publication | Abbreviated Journal | ||
| Volume | Issue | Pages | |||
| Keywords | |||||
| 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. |
