Ethical equitation: Capping the price horses pay for human glory

Ethical equitation is nowadays coming into sharp focus in equestrian culture. Concerns surround the ethics of sports based on controlling an animal's locomotory responses and in using animals such as horses in sport in general. Anthropomorphically labeled misinterpretations of the responses of trained horses, such as the use of terms like “mad,” “lazy,” “keen,” and “stubborn,” may be detrimental to optimal equine welfare. Similarly, the concept of the “equine athlete” may imply an ill-informed teleological explanation of the motives of the horse in sport. Despite problems in identifying the happy horse, rewarding optimal welfare and the absence of critical stress responses in performance horses is an important step forward.Horse racing is the source of many welfare concerns because of the use of the whip and the physical dangers to horses involved in hurdle racing and steeplechasing. The use of the whip in racing is controversial and, because it does not always lead to acceleration, problematic. There is a pressing need for learning theory to be adopted in all equestrian pursuits, because such an approach would obviate the need for whips, punishment, and the use of fear in escape learning. In other disciplines, practices such as hyperflexion and soring have a significant potential to compromise the welfare of the horse in sport.The future of horse sports should involve abandoning the mandatory use of primitive control devices, such as curb bits, that have a real potential to cause harm. International governing bodies and national equestrian federations ought to proceed with removing any requirements to use curb bits and judges should reward riders who use the most humane control devices at the higher levels of competition.Finally, horse breeding should also be scrutinized under an ethical spotlight. Selecting horses on the basis of temperament has inherent risks, including lowered motivation of riders and trainers to refine their training skill set, which may also lead to significant wastage. Pure breeding risks the health and welfare of horses owing to increases in homozygous deleterious genes expressing themselves.     

A Note on the Heritability of Reactivity Assessed at Field Tests for Danish Warmblood Horses

Temperament traits in horses, especially reactivity, are an important trait in relation to human–horse accidents and the welfare of the horses. However, so far, temperament is often not included in many horse breeding programs. Most of the behavioral genetic studies in horses have been based on indirect indications of a sire effect and not on estimations of the heritability of temperament traits. Therefore, the aim of this study was to estimate the heritability of behavior reactions related to reactivity observed in a practical situation, that is, during the evaluation of the conformation of the horse at field tests. The study included 323 3-year-old Warmblood horses. Data were analyzed according to an animal model, and the estimation was based on restricted maximum likelihood. Results showed a low (0.17) heritability of reactivity. Probably because of the limited number of horses in the study, a high standard error was untainted. Nevertheless, results suggested a genetic variation of reactivity when assessed at field tests, but further research is needed before reactivity can be incorporated as a selection criteria into a breeding program.     

Relationships between young stallions’ temperament and their behavioral reactions during standardized veterinary examinations

Horse handling and veterinary examination can induce hazardous stress reactions. Such reactions occur especially in young and less-trained horses, particularly stallions, and make their handling a risk for breeders, grooms, and medical staff. Moreover, these stressful situations will affect the animal’s health and welfare. Because stress reactivity is thought to be partly determined by genetic factors, scientists, veterinarians, and breeders are likely to be interested in adding temperament assessments to stallion selection schemes, as it is already done in some countries. This study assesses young stallions’ temperament and its comparison with their stress reactions during a standardized veterinary examination for studbook admission. The assessment consists of a general examination, a lameness examination including flexion tests, an endoscopy of the upper airway, and a standardized radiological examination. During the years 2008 and 2009, 93 stallions were evaluated. Stallions were observed from the moment they were unloaded from the trailer at the clinic until the end of veterinary examinations. In addition to the behavioral observations made by the experimenter, each staff member in charge of the examination filled in a short questionnaire about the horse’s temperament and the “easiness of manipulation” for the performed examinations. Breeders were asked to complete a longer questionnaire about their horse’s temperament. The assessments of “aggressiveness,” “sociability,” and “learning level” temperament traits were the most consistent, as shown by the significant Spearman correlations between judges’ assessments. Undesirable behaviors during veterinary examinations leading to handling difficulties were associated with a low “easiness of manipulation” score assessed by the clinical staff. These low “easiness of manipulation” scores were positively correlated to temperament traits such as “anxiousness” and “aggressiveness” and negatively correlated to others such as “sociability” or “learning level.” Temperament assessment and behavioral observations can therefore be used to anticipate behaviors that make a horse difficult to handle during veterinary examinations. Thus, it may be important to include temperament assessment as a feature in the selection of breeding stallions—as already practiced for some breeds in some countries. Such evaluations may promote the welfare of horses and ease of handling as well as safety for the handler.

Ethical equitation: Applying a cost-benefit approach

Riding and training horses is the basis of a multi-billion dollar industry, but their use in the developed world is predominantly for recreational, competitive, entertainment, or performance purposes. However, when we consider the poor welfare outcomes for the horses involved, our ultimate focus on fun seems a poor justification for using horses in this way. This article is not intended to diminish the use of horses in the ridden context, rather it foreshadows a time when horse welfare and equestrian competition are as balanced and sustainable as possible.Any use of horses is inevitably associated with a range of activities and interventions that can, collectively, compromise welfare. Laws are unlikely to adequately protect horse welfare if they assume traditional practices, including the use of the whip to accelerate horses, to be “reasonable” and “acceptable” without regard to their effect. Objective measures of the influence of training and riding methods on horse welfare are needed, along with a more sophisticated ethical framework than legislation or codes currently provide.Using a cost-benefit analysis approach is one way to test the acceptability of our impacts on horses. This requires that welfare costs associated with an activity can be reliably estimated and balanced against the potential benefits of the activity to both humans and horses. To justify our use of horses for fun, we must have a strong moral obligation to ensure that we do everything possible to avoid jeopardizing their welfare.In other areas of animal use, particularly research, ethical models permit objective comparisons of the relative impact of different activities through “impact scales.” We propose the adaptation of such models for use in equestrian contexts to identify ways to improve ridden horse welfare.The challenge to equestrians is to maintain current levels of difficulty in competition without compromising horse welfare—for example, relying more on the skill of the trainer and rider and removing devices and training methods that negatively affect the horse.     

Rider and Horse Salivary Cortisol Levels During Competition and Impact on Performance

During competition, stress may affect riders and horses. This stress can affect health, welfare, and/or performance. Our aim was to quantify stress levels during competition in horses and riders. We also searched relationships between these stress levels and performance. Twenty riders and 23 horses were followed up during a show-jumping event (26 courses) held at a riding school. Regular saliva samples taken from horses and riders were assayed to evaluate cortisol levels. We studied salivary cortisol evolution during the days of competition. There was no correlation between instantaneous sampling on horses and their riders. However, we did find a parallel between horse and rider salivary cortisol evolution curves, with a similar peak, reached 20 minutes after the course. The increase was stronger in riders than in horses. Correlations appeared between salivary cortisol concentration and performance, but stress in both partners seems to have an opposite influence on performance. Riders who showed a higher salivary cortisol increase were awarded more penalties, whereas horses that showed a higher increase in salivary cortisol performed better. Stress level measurement in rider–horse pairs would thus lead to improvement in competition conditions and performance, for horses as well as for riders.     

Analysis of new temperament traits to better understand the trait spirit assessed in breeding field tests for Icelandic horses

This study investigated different aspects of the trait spirit that is routinely recorded in breeding field tests (BFTs) for Icelandic horses. Genetic parameters were estimated for spirit and six newly introduced temperament suppleness traits assessed by judges and riders in Icelandic BFTs, and for everyday life temperament traits assessed by owners of breeding horses in 2014 and 2015. The findings suggested moderate heritability for some temperament traits assessed by riders in BFTs and showed that the assessment method needs to be improved in order for judges to discern the variation in these traits. Furthermore, according to estimated correlations the score for spirit described only part of the general temperament of the horse, where aspects of general nerve strength was not well covered. Nevertheless, no clearly unfavourable correlations with spirit were found and the majority of horse owners surveyed in this study were satisfied with the assessment for spirit.     

Diversity in horse enthusiasts with respect to horse welfare: An explorative study

A reduced level of welfare of horses is related to management factors such as low forage feeding, short feeding time, social isolation, and lack of unrestrained exercise. It has been assumed that welfare problems can be reduced and/or partly prevented by improving the knowledge and skills of horse enthusiasts. It has also been assumed that to improve the provision of information to horse enthusiasts, it is important to explore and gain more insight into horse enthusiasts’ motives, knowledge, and behavior. The aim of this exploratory study was to identify the diversity of horse enthusiasts in the Netherlands, with respect to the way they search and find out information, their emotional involvement with horses, and their attitude, their knowledge, and daily practices with regard to equine welfare. A Web-based survey using a 30-item questionnaire resulted in 4,267 respondents. Most respondents (84.6%) were female; the average age of the respondents was 34.2 (±13.5) years. More than half of the respondents (64.5%) believed that there were welfare problems throughout the whole horse industry. The most important reported source for information was the personal contact with other horse enthusiasts (82.8%), with veterinarians (74.5%), and with farriers (69.5%). It is, therefore, recommended that to disseminate relevant knowledge on equine welfare, particular attention should be paid to the acquisition and dissemination skills within the education programs of veterinarians and farriers. Although most respondents were aware of the issues that can compromise welfare, their knowledge did not always result in appropriate practices. Furthermore, a cluster analysis showed that horse enthusiasts can be categorized into 4 clusters from the way they search and find out information, their emotional involvement with horses, and their attitude, their knowledge, and daily practices with regard to the welfare of horses. To improve the provision of information to horse enthusiasts, it is recommended that the information provision to horse enthusiasts is organized around these 4 clusters of horse enthusiasts.     

Assessment of ridden horse behavior

Assessments of the behavior of ridden horses form the basis of performance evaluation. The purpose of any performance being evaluated will determine the factors considered important, factors indicative of “poor” performance, and what makes a successful equine athlete. Currently, there is no consistent objective means of assessing ridden horse behavior, and inevitably, given the different equestrian disciplines, the likelihood of a universal standard of good and bad performance is remote. Nevertheless, to protect the welfare of the ridden horse regardless of its specific role, we should strive for consensus on an objective means of identifying behavioral signs indicative of mental state. Current technological developments enable objective evaluation of movement patterns, but many aspects of the assessment of ridden behavior still rely on subjective judgment. The development of a list of behaviors exhibited by ridden horses, a ridden horse ethogram, will facilitate recording of observable behavioral events. However, without objective evidence of the relevance of these behavioral events, such a resource has limited value. The aim of this review was to investigate potential sources of such evidence and relate these to the assessment of ridden horse behavior. The current and potential contribution that further objective measures can make in this process is evaluated. We believe that the only way to improve the welfare of the ridden horse is by objectively identifying behavioral signs that indicate that the horse is either comfortable or uncomfortable with the activity in which it is participating. After there is clear evidence to support this, appropriate adaptation of performance criteria in all disciplines can proceed along with alignment in training systems that ensures a mutually positive experience for both horse and human partners.     

Heritability of foot conformation and its relationship to sports performance in a Dutch Warmblood horse population

Reasons for performing study: Warmblood horse studbooks aim to breed horses with a conformation that will enable elite future performance, but reduce the risk of injuries and lameness. Negative conformational traits, such as asymmetrical or ‘uneven’ forefeet would possibly diminish performance. Objectives: To assess the prevalence and heritability of uneven feet and its genetic relationship to other conformation traits as well as to sporting performance later in life in Warmblood riding horses. Methods: The databases of the Royal Dutch Warmblood Studbook (KWPN, n = 44,840 horses) and Royal Dutch Equestrian Sports Federation (KNHS, n = 33,459 horses in dressage and n = 30,474 horses in showjumping) were linked through the unique number of each registered horse. Therefore, heritabilities and genetic and phenotypic correlations could be estimated from the scores of the jury at studbook admission and the sports performance of that population in dressage and jumping over the period 1990–2002. Results: The prevalence of uneven feet was 5.3% on average, and increased from under 4.5% during the first 3 years of recording to over 8% in the years from 2000 onwards. Heritability estimates of foot conformation traits were moderate and ranged from 0.16 for heel height to 0.27 for hoof shape. The genetic correlation between the trait of uneven feet and performance in competition was negative but weak: ?0.09 with dressage and ?0.12 with showjumping. Conclusions: Predisposition to uneven feet can be reduced by selection. Because of weak genetic correlations, the increased prevalence is not directly associated with selection for better sports performance or higher conformation grade. If the trait ‘uneven feet’ arises from a disproportionate relationship between height at the withers and neck length, then selection on conformation grade might result in development of uneven feet. In general, limb conformation has a moderate genetic relationship to conformation grade and foot conformation traits have a genetic relationship to sporting performance. Reducing occurrence of uneven feet by selection is possible, without limiting progress in sport performance.     

Morphological analysis and effect of selection for conformation in the Noriker draught horse population

To evaluate the breeding program in the Austrian Noriker draught horse population, which is mostly based on conformation, 31 body measurements from 497 horses in seven breeding areas of Austria were recorded. In addition, the data of 2376 horses (the current breeding population) from the studbook, containing 10 scored conformation traits and 4 body measurements per individual, were analysed. We assumed breeding regions, coat colour strains and breeding classes assigned according to conformation evaluation to be the main factors in phenotypic diversity of this Austrian draught horse breed. Significant differences and distances were found for all of these factors. Whereas differences between breeding areas mostly are due to housing conditions and feeding strategies, the breeding classes provide a very distinct picture of the current trends in Noriker breeding. Breeding organisations favour a long and high Noriker draught horse, a tendency that is the same for all departments. Heritability estimates for morphological traits vary from 0 to 0.67, and from 0.08 to 0.37 for linear type traits.     

Genetic parameters estimation in an Italian horse native breed to support the conversion from agricultural uses to riding purposes

Horses are nowadays mainly used for sport and leisure purposes, and several local breeds, traditionally used in agriculture, are exposed to the risk of extinction. The long-term survival of local horse breeds depends on strategies to both monitor their genetic diversity and to find their sustainable role in the equine market. Thus, several local horse breeds need to adapt their breeding objective to allow a modernization process. The Bardigiano is an example of such horse breeds; we, therefore, studied the existing evaluation protocol from a genetic standpoint to assess the protocol's suitability to convert the Bardigiano from an agricultural to a riding horse. To this end, we estimated genetic parameters for four conformation measurements, ten grading traits and 23 linear traits. For conformation measurements, the heritabilities ranged from 0.31 for cannon bone circumference to 0.63 for height at withers. For conformation and attitude grading traits, the highest heritability (0.34) was estimated for development and the lowest (0.09) for gaits. The heritabilities for linear traits ranged from 0.05 for the leg straightness to 0.32 for the coat colour. Genetic correlations between linear traits and corresponding grading traits varied considerably, ranging from −0.42 to 0.98. This study showed that the current evaluation protocol in the Bardigiano horse is appropriate for genetic evaluation. Genetic parameters estimation can, in turn, be used to develop novel breeding values to help this conversion. Our study paves the way to optimize the Bardigiano horse breeding programme, and it may help several other local horse breeds experiencing similar issues.     

Changes in Eye Temperature and Stress Assessment in Horses During Show Jumping Competitions

High stress levels in horses during sporting events can influence the animal’s performance in competitions as well as their welfare. This study investigated the use of infrared thermography (IRT) measurement as a rapid, noninvasive, and accurate method for stress assessment in horses during sport competitions and compared IRT with a commonly used physiological method used for stress assessment and salivary cortisol. IRT and salivary cortisol responses were measured 3 hours before the competition, immediately following the competition, and 3 hours after the competition, each day during the 3 days of a show jumping event. Salivary cortisol values ranged from −0.11 ± 4.51 ng/mL in 5-year-old animals to 1.10 ± 2.20 ng/mL in 4-year-old animals, whereas eye temperature values ranged from 35.84 ± 1.16°C in 6-year-old animals to 36.08 ± 1.11°C in 5-year-old animals. The results obtained suggested that IRT measurements constitute an effective method for detecting stress in horses subjected to the acute events of show jumping.     

Owners' perceptions of the health and performance of Pony Club horses in Australia

Pony Club is one of the leading junior equestrian organisations in the world, and was established to teach young people the many aspects of horsemanship. The aim of this study was to gain an understanding of the health and performance of Pony Club horses from the perspective of their owners. In-depth interviews were conducted with Pony Club members at two sites in Australia, and topics relating to participants' background with horses, horse attributes valued by participants, horse health and performance, and Pony Club-related matters. The in-depth interviews were taped, transcribed and analysed, by describing the themes and issues recorded in the dialogue and conducting cross-case analysis (finding similarities and dissimilarities between participants with respect to each of the above-mentioned topics). A total of 32 interviews were conducted. The participants' background with horses varied greatly. The horse attributes valued by > or =59% of participants included temperament, size, ability and suitability for riders. A range of issues relating to health and performance were important to > or =53% of participants, including horse temperament, nutrition, internal parasites, lameness and foot-care, and colic. Soundness and preventive health measures were rarely mentioned (< or =16% of participants). Friends or knowledgeable horse people were identified as the first point of contact for horse-health matters, and veterinarians were only used as a last resort or for serious problems. Members of Pony Club learned about their horses by trial and error. Optimal performance was described as a horse that was willing to do as the rider asked. Poor performance was usually the result of the horse misbehaving, and could include a resistance to rider commands, pigrooting and bucking.     

Stress Reactivity and Coping in Horse Adaptation to Environment

“Coping” or “coping strategy”, defined as the behavioral and physiological efforts of animal to master the situation, is more and more in interest of researchers dealing with applied animal behavior and welfare. Knowledge about “coping styles” may be helpful in understanding individual adaptive capacity to stressful events. At least two types of animal coping strategy (or coping style) can be involved: (1) active copers (proactive) and (2) passive copers (reactive). The individual differences in stress response to threatening situations have been found in horses, and these animals can show specific coping strategies such as other species. This article reviews the set of behavioral, psychoneuroendocrine, and psychoneuroimmune mechanisms involved in animal adaptation to environmental challenges and discusses the relationship between behavioral and physiological factors involved in stress response of the horse. Exploring coping strategies in horses and in any captive animal can be successful when a multidimensional approach including behavioral, neural, hormonal, and hematological measures is considered. Knowledge on stress coping styles can provide valuable information to predict the behavior of individuals during response to specific challenging situations. Moreover, assessing individual differences in adaptation strategies can be useful in horse selection to different exploitation tasks and reproduction.     

Practical considerations regarding the implementation of a temperament test into horse performance tests: Results of a large-scale test run

Considering the ever-growing demand of various breeding organizations for an objective, inexpensive, reliable, and easily conducted assessment of the behavior of horses, the aim of our study was to implement a novel-object test and a startling test into any kind of breeding performance testing to assess horses' temperament. Additionally, the influence of testing areas (familiar or unfamiliar), riders, and horse factors such as levels of training, breed, and age were of interest. Furthermore, recommendations for the practical implementation concerning the parameters should be given. Therefore, 1,028 horses over a period of 3 years participated in a temperament test consisting of 5 different stimuli. The horses were either ridden (61.8 %) or led by hand (38.2 %) by an unfamiliar professional rider (N = 43) or a familiar rider (N = 20). Live behavioral observations were taken by a trained observer. Overall, horses' scores for reactivity in the present temperament test were distributed over the whole scale, with lower means and higher standard deviations (6.7 ± 2.2-7.6 ± 2.1) than corresponding scores from the conventional personality evaluation in performance tests (7.7 ± 0.8-8.2 ± 0.5; P < 0.01). High correlations (r = 0.3-0.9; P < 0.001) between the scores for reactivity and the other behavioral parameters (emotional expression, activity, time to calm down, rider's aids) show a large influence of these parameters in assessing the horses' temperament. Factors like breed type, sex, and age had significant influences (P < 0.001) on different scores of the temperament test. In most cases, the rider or handler had no influence on the different scores assessed during the temperament test. The training level and the testing modus never had a significant influence on different scores. Only the testing station or location had a small influence on the scores for the stimulus “bridge” in some horses. Based on the results, it could be concluded that an implementation of a temperament tests into performance testing is possible during various types of testing procedure. Especially the assessment of reactivity, emotional expression, interest in the stimulus and rider's aids during and after passing the stimulus, as well as the time to calm down are important parameters for analyzing the horses' personality.     

Diagnosis, treatment, and farriery for horses with chronic heel pain.

In conclusion, horses with heel or navicular area pain vary, and no one treatment option is suitable for all horses. Each horse must be evaluated individually to determine which structure in the palmar aspect of the foot is injured, severity of disease, horse and hoof conformation, and horse use and level of performance expectation before a treatment plan can be developed. Overall, there are many treatment options to help these horses to perform their intended athletic event.     

How riding may affect welfare: What the equine veterinarian needs to know

Veterinarians generally focus on keeping the performance horse in work but they need to be mindful of ways in which the work itself may jeopardise the animal's welfare and health. Elements of a horse's work may expose it to the risk of injury but insults to wellbeing, which are far more common and far more sustained, although less overt, also deserve consideration. A good example is the way in which chronic physiological stress responses arising from inhumane training techniques may compromise immunity and tissue repair. This article explores the physiological and musculoskeletal insults that can result from ridden work, alongside the gear and training paradigms that can compromise welfare. It also considers issues relating to the use of pharmaceuticals in the ridden horse. With stress reduction as a primary focus, it emerges that veterinarians are uniquely placed to comment on the somatic effects of psychological stressors, including the social and ethological challenges resulting from the work required of the so‐called elite equine athlete. Whether the profession will step up to meet this significant challenge is also discussed.     

Genetic correlations between competition traits and traits scored at breeding field-tests in Icelandic horses

Relationships between breeding field-test traits and competition traits were studied to investigate whether the latter could be usefully included in the genetic evaluation of Icelandic horses. The current method of genetic evaluation is based on records from breeding field-tests only. The breeding field-test data included 16 401 individual records of Icelandic horses evaluated in 11 countries during 1990–2005. Competition results included 18 982 records of 3790 horses competing in sport and gæðinga competitions in Iceland and Sweden during 1998–2004. In the breeding field-tests, eight conformation traits and eight riding ability traits were scored; height of withers was also recorded. These traits were analysed together with the competition traits tölt(comp), 4-gait, 5-gait and pace test, in bivariate analyses. Animal models were used; the fixed effects for breeding field-test traits included sex by age interaction and country by year interaction. For the competition traits the model included fixed effects of sex, age and event, and a random permanent environmental effect. Estimated heritabilities and genetic correlations for breeding field-test traits were consistent with earlier results; heritabilities ranged from 0.20 to 0.67, and moderate to high genetic correlations were estimated between many of the riding ability traits, and between riding ability traits and some conformation traits. The estimated heritabilities for competition traits were about 0.20, and genetic correlations between competition traits varied from − 0.12 to 1.00. In general, high genetic correlations were estimated between breeding field-test riding ability traits and competition traits. Moderately positive genetic correlations were found between some breeding field-test conformation traits and competition traits. Competition traits add information relating to the breeding goal of the Icelandic horse; they should therefore be added to genetic evaluation in future.
