	Title	Development of an ethogram for a pain scoring system in ridden horses and its application to determine the presence of musculoskeletal pain			Type	Journal Article
	Year	2018	Publication	Journal of Veterinary Behavior	Abbreviated Journal
	Volume	23	Issue		Pages	47-57
	Keywords	Lameness; Equine behavior; Pain grading; Headshaking; Bucking; Rearing
	Abstract	There is evidence that more than 47% of the sports horse population in normal work may be lame, but the lameness is not recognized by owners or trainers. An alternative means of detecting pain may be recognition of behavioral changes in ridden horses. It has been demonstrated that there are differences in facial expressions in nonlame and lame horses. The purpose of this study was to develop a whole horse ethogram for ridden horses and to determine whether it could be applied repeatedly by 1 observer (repeatability study, 9 horses) and if, by application of a related pain behavior score, lame horses (n = 24) and nonlame horses (n = 13) could be differentiated. It was hypothesized that there would be some overlap in pain behavior scores among nonlame and lame horses; and that overall, nonlame horses would have a lower pain behavior score than lame horses. The ethogram was developed with 117 behavioral markers, and the horses were graded twice in random order by a trained specialist using video footage. Overall, there was a good correlation between the 2 assessments (P < 0.001; R2 = 0.91). Behavioral markers that were not consistent across the 2 assessments were omitted, reducing the ethogram to 70 markers. The modified ethogram was applied to video recordings of the nonlame horses and lame horses (ethogram evaluation). There was a strong correlation between 20 behavioral markers and the presence of lameness. The ethogram was subsequently simplified to 24 behavioral markers, by the amalgamation of similar behaviors which scored similarly and by omission of markers which showed unreliable results in relation to lameness. Following this, the maximum individual occurrence score for lame horses was 14 (out of 24 possible markers), with a median and mean score of 9 (±2 standard deviation) compared with a maximum score of 6 for nonlame horses, with a median and mean score of 2 (±1.4). For lame horses, the following behaviors occurred significantly more (P < 0.05, chi-square): ears back, mouth opening, tongue out, change in eye posture and expression, going above the bit, head tossing, tilting the head, unwillingness to go, crookedness, hurrying, changing gait spontaneously, poor quality canter, resisting, and stumbling and toe dragging. Recognition of these features as potential indicators of musculoskeletal pain may enable earlier recognition of lameness and avoidance of punishment-based training. Further research is necessary to verify this new ethogram for assessment of pain in ridden horses.

	Abstract	Zusammenfassung Die vorliegende Abhandlung entspringt dem Aufgabenkreis einer jungen Arbeitsgemeinschaft zwischen Geisteswissenschaft und vergleichender Psychologie, die das wichtigste Programm des neugegründeten Philosophischen Institutes der Albertus-Universität in Königsberg darstellt. Sie ist aus der einen Abteilung dieser Anstalt, dem Institut für vergleichende Psychologie hervorgegangen. Obwohl sie eine ganze Reihe unveröffentlichter neuer Beobachtungen und Versuche enthält, stehen diese nicht genug im Mittelpunkte der Untersuchung, um eine Zusammenfassung von Ergebnissen in jener Form möglich zu machen, wie sie sonst in der induktiven Naturforschung üblich ist. Immerhin aber herrscht die induktive Denkweise in der vorliegenden Arbeit so stark vor, daß eine kurze Zusammenfassung angebracht erscbeint, wenn sie auch notgedrungen die Form einer kurzen Inhaltsangabe annehmea muß.

	Title	Do horses with poor welfare show 'pessimistic' cognitive biases?			Type	Journal Article
	Year	2017	Publication	The Science of Nature	Abbreviated Journal	Sci. Nat.
	Volume	104	Issue	1	Pages	8
	Keywords
	Abstract	This field study tested the hypothesis that domestic horses living under putatively challenging-to-welfare conditions (for example involving social, spatial, feeding constraints) would present signs of poor welfare and co-occurring pessimistic judgement biases. Our subjects were 34 horses who had been housed for over 3 years in either restricted riding school situations (e.g. kept in single boxes, with limited roughage, ridden by inexperienced riders; N = 25) or under more naturalistic conditions (e.g. access to free-range, kept in stable social groups, leisure riding; N = 9). The horses' welfare was assessed by recording health-related, behavioural and postural indicators. Additionally, after learning a location task to discriminate a bucket containing either edible food ('positive' location) or unpalatable food ('negative' location), the horses were presented with a bucket located near the positive position, near the negative position and halfway between the positive and negative positions to assess their judgement biases. The riding school horses displayed the highest levels of behavioural and health-related problems and a pessimistic judgment bias, whereas the horses living under more naturalistic conditions displayed indications of good welfare and an optimistic bias. Moreover, pessimistic bias data strongly correlated with poor welfare data. This suggests that a lowered mood impacts a non-human species' perception of its environment and highlights cognitive biases as an appropriate tool to assess the impact of chronic living conditions on horse welfare.

	Title	Does Carrying a Rider Change Motor and Sensory Laterality in Horses?			Type	Journal Article
	Year	2022	Publication	Animals	Abbreviated Journal	Animals
	Volume	12	Issue	8	Pages	992
	Keywords	laterality; horse; rider; sensory laterality; motor laterality; novel object; side preference
	Abstract	Laterality in horses has been studied in recent decades. Although most horses are kept for riding purposes, there has been almost no research on how laterality may be affected by carrying a rider. In this study, 23 horses were tested for lateral preferences, both with and without a rider, in three different experiments. The rider gave minimal aids and rode on a long rein to allow the horse free choice. Firstly, motor laterality was assessed by observing forelimb preference when stepping over a pole. Secondly, sensory laterality was assessed by observing perceptual side preferences when the horse was confronted with (a) an unfamiliar person or (b) a novel object. After applying a generalised linear model, this preliminary study found that a rider increased the strength of motor laterality (p = 0.01) but did not affect sensory laterality (p = 0.8). This suggests that carrying a rider who is as passive as possible does not have an adverse effect on a horse�s stress levels and mental state.

	Title	Does Music Influence Emotional State in Race Horses?			Type	Journal Article
	Year	2015	Publication	Journal of Equine Veterinary Science	Abbreviated Journal
	Volume	35	Issue	8	Pages	650-656
	Keywords	Cardiac activity; Emotional state; Music; Race horse
	Abstract	The aim of the study was to determine the effect of music featured in the barn, on the emotional state of race horses. Seventy 3-year-old Purebred Arabian horses in their first race season were divided into experimental group (EXP) of 40 horses and control group (CNT) of 30 horses and placed in separate barns. The EXP was subject to specifically composed music featured in the barn for 5 hours in the afternoon during the whole study. The emotional state in the horses was assessed at rest, saddling, and warm-up walk under rider. Measurements were taken six times, every 30 to 35 days, starting from the beginning of featuring the music. The horse's emotional state was assessed by cardiac activity variables. The music effect on the emotional state was also considered with regard to the horse's performance estimated by race records. The cardiac activity variables were compared with repeated measures design, whereas race records were analyzed with analysis of variance generalized linear model. The music positively affected the emotional state in race horses. The influence was noticeable already after the first month of featuring the music and increased in the second and third months. Despite the fact that later the variables began to return to initial levels, a positive effect of the music on prizes won by the horses in the EXP compared to the CNT was found (P < .05). The results suggest that the music may be featured in the barn, preferably for 2 to 3 months as a means of improving the welfare of race horses.

	Title	Dominance and Leadership: Useful Concepts in Human-Horse Interactions?			Type	Journal Article
	Year	2017	Publication	Journal of Equine Veterinary Science	Abbreviated Journal	Proceedings of the 2017 Equine Science Symposium
	Volume	52	Issue		Pages	1-9
	Keywords	Horse; Social order; Dominance hierarchy; Aggression; Injury; Learning; Training
	Abstract	Dominance hierarchies in horses primarily influence priority access to limited resources of any kind, resulting in predictable contest outcomes that potentially minimize aggressive encounters and associated risk of injury. Levels of aggression in group-kept horses under domestic conditions have been reported to be higher than in their feral counterparts but can often be attributed to suboptimal management. Horse owners often express concerns about the risk of injuries occurring in group-kept horses, but these concerns have not been substantiated by empirical investigations. What has not yet been sufficiently addressed are human safety aspects related to approaching and handling group-kept horses. Given horse's natural tendency to synchronize activity to promote group cohesion, questions remain about how group dynamics influence human-horse interactions. Group dynamics influence a variety of management scenarios, ranging from taking a horse out of its social group to the prospect of humans mimicking the horse's social system by taking a putative leadership role and seeking after an alpha position in the dominance hierarchy to achieve compliance. Yet, there is considerable debate about whether the roles horses attain in their social group are of any relevance in their reactions to humans. This article reviews the empirical data on social dynamics in horses, focusing on dominance and leadership theories and the merits of incorporating those concepts into the human-horse context. This will provide a constructive framework for informed debate and valuable guidance for owners managing group-kept horses and for optimizing human-horse interactions.

	Title	Dynamic evolution of bitter taste receptor genes in vertebrates			Type	Journal Article
	Year	2009	Publication	BMC Evolutionary Biology	Abbreviated Journal
	Volume	9	Issue	1	Pages	12
	Keywords
	Abstract	Sensing bitter tastes is crucial for many animals because it can prevent them from ingesting harmful foods. This process is mainly mediated by the bitter taste receptors (T2R), which are largely expressed in the taste buds. Previous studies have identified some T2R gene repertoires, and marked variation in repertoire size has been noted among species. However, the mechanisms underlying the evolution of vertebrate T2R genes remain poorly understood.

	Title	Early development of gait asymmetries in trotting Standardbred colts			Type	Journal Article
	Year	1987	Publication	Equine Veterinary Journal	Abbreviated Journal	Equine. Vet. J.
	Volume	19	Issue	3	Pages	189-191
	Keywords
	Abstract	Summary Ten trotting Standardbred colts were recorded by high-speed cinematography at the ages of eight, 12 and 18 months. The horses were trotting on a treadmill operating at 4.0 m/secs. Five horses were subjected to a programme of intensified training from eight months of age, whereas the others were not trained and acted as controls. The films were analysed on a semi-automatic film-reading equipment and a number of variables used to demonstrate the gait symmetry were calculated and scaled by computer. Certain differences between left and right diagonal and contralateral pair of limbs, respectively, were noted, suggesting that laterality in horses may be inherited. The most pronounced systematic differences were found in 18-month old horses in the trained group. The results show the importance of careful gait examination and comprehensive coordination training at an early age.
