Horseshoe is used to avoid the failures of horse's hooves due to extreme impact and wear loads. The horse's hooves are repeatedly subjected to loadings during walking, trotting, running and jumping. In this research, we introduce a newly developed horseshoes made of polymeric composite materials. The horseshoes are placed inside the leather boot; it is a specially designed for horse. The process of making horseshoes and horse boots were discussed and the responses of the horse shoes as well as horses were analyzed. The horses were subjected to a series of testing, e.g., walking, trotting, and running. The result of the tests indicate that horseshoes and horse boots are quite strong, light, and safe to be used on horses. The response of horses shows that the horseshoe and boots are quite comfortable for them. This can be seen because there are no significant behavioral changes of the horse before and after wearing the boot. After being used to, it was shown that there is no damage or crack of the horseshoe. Therefore, it can be concluded that the composite horseshoe is safe and good to be used as horseshoe material.

AbstractThe aim of this study was to investigate how difficult it was to halter and separate a horse (Equus caballus) from a group for riding or training purposes and to describe how human-horse interactions could affect this common procedure. A total of 20 different horse groups, with a minimum of five horses in each, were studied on 14 farms in Norway, from June to October 2007. On each farm, information about the facilities, the horse and the handler was recorded. In each group, the horse owner or keeper (handler) was asked to enter the group, approach his/her horse, halter it and lead it out through the gate, then keep the horse standing out of sight from other horses for two minutes. The entire procedure was video recorded and the behaviour of the target horse, handler and other horses was subsequently scored. Only one of the 100 horses moved away from the handler when approached. Ninety-six percent of the target horses followed their handler without showing any resistance. In 75% of the tests, the other horses did not interact with the target horse and/or handler. At the gate, 26% of the handlers did not turn the target horse around before closing the gate, thereby placing themselves in a vulnerable position, with their body in very close proximity to the horse's hind legs. In conclusion, separating a horse from its group can be considered relatively safe and unproblematic, provided good management practices and trained handlers.

The horses were trotted in a straight line, and the acceleration data were recorded from the movement of the horse’s head. Inertial sensors were used to collect the information. The sample entropy was used to characterize the dynamics of horse gait. The gait of sound and lame horses was compared, and the sound horses had smaller values of the sample entropy. The effects of sedative detomidine on the gait of lame horses were also examined. The values of sample entropy for sedated horses were smaller than the values of the sample entropy for untreated horses. The sample entropy can provide important information about the dynamics of the equine gait.

The article analyzes the evaluation of the horse’s behavior according to the methodology developed by the authors and designed for the selection of “hobby class” horses for use in amateur equestrian sports and horse riding. The methodology is a point-based system for evaluating behavior according to certain criteria, with each of them being assigned 0 to 4 points in the interaction between a horse and a person. The average score determines the degree of suitability of a horse as a “hobby class” animal. Mares were found to be the most suitable for use as amateur sport horses, while there were no breed or age differences in the behavior of the horses. Behavioral and economic indicators of horse use were also compared. It was found that animals with high behavior scores, 3.0 points and above, were more likely to be used by inexperienced riders. The income from this group of horses was higher compared to those with low behavior scores.

Texto completo da fonteResumo:
Obesity in horses and ponies, is according to many equine related charities (Blue Cross, BHS) becoming an increasing welfare problem. Recent studies have linked equine obesity and insulin resistance with development of debilitating laminitis (Vick et al., 2007). Poor nutritional management and sedentary lifestyles are to blame for the growing proportion of obese horses (Buff et al., 2005). The horse carer is responsible for the health and welfare of the horse and as such should monitor the weight, condition and exercise regime to ensure appropriate fitness levels to maintain health and performance. Indeed, Johnson (2002) reports that certain management practices tend to promote the development of obesity in mature horses as they enter their teenage years. Horse owners must therefore consider management practices throughout the horse’s life, as the provision of starch-rich and fat-supplemented rations to healthy horses that are relatively inactive may promote the development of obesity increasing the risk of laminitis (Johnson, 2002). The aims of this research were to ascertain the condition score and fitness levels of horses and ponies when diagnosed with laminitis, as reported by the horse carer and to gain insight into how these factors may influence the health and welfare of the domestic horse.

This work aims to describe the Mangalarga Marchador horse’s breeding systems in the Rio de Janeiro. The geographic distribution of the farms in the mesoregions of Rio de Janeiro State were defined, and the commercial and social importance the Mangalarga Marchador horse’s business is described in this study. Mangalarga Marchador horse breeders were interviewed through a survey. Sampling of the farms was stratified by the mesoregions. The state of Rio de Janeiro has 1,573 members Horse Breeder Association, with 92,162 registered horses, corresponding to 15.43% of the total of Mangalarga Marchador horses in Brazil. Approximately 95.2% of farms have their own area and more than half ranging between 100 to 500ha. Horse breeding is the main activity on 79.2% of the farms, and the main goal is the sale of horses (39%), followed by sports (32.7%) and leisure (18.6%). The properties have, on average, five registered employees. Most of the owners (90%) are male. The average number of horses at these farms is 100 heads, with an average number of 53 mares, maintained mainly on an extensive production system. About 39.9% of pastures are formed by the Brachiaria spp. grass, and Napier grass, also known as Elephant grass, the most used forage supplement. The average monthly consumption of forage and commercial concentrate feed is 12,866kg and 2,800kg respectively per farm. About 90% of breeders declared that the unskilled labor force is the biggest obstacle to the increase of the horse breeding in the Rio de Janeiro.

Background: The physiological status of a horse is an indicator of its health. Parameters that can be used to determine the health status of a horse include respiratory rate, heart rate, and body temperature. As the activity of a horse increases, its respiratory rate increases. By measuring respiratory rate, heart rate, and body temperature before and after training, changes in the physiological status of a horse can be determined. Purpose: This study aims to provide an overview of the physiological status of horses before and after training at Anantya Riding Club. Case: Physiological status of horses before and after training. Case Management: This study used a qualitative approach. Data on the physiological conditions of horses were collected before and after training. A digital thermometer was used to measure body temperature. A stethoscope was used to measure heart rate. Respiratory rate was measured by placing the back of the hand or the palm of the hand close to the horse's nose to feel its breath. These measurements were taken before and after training. Conclusion: This study concluded that the physiological status of horses after training showed an improvement. The average body temperatures of the horses before and after training were [37.6 ± 0.09]°C and [38.61 ± 0.03] °C, respectively. The average heart rates of the horses before and after training were 41.0 ± 2.4 beats/minute and 90.2 ± 3.5 beats/minute, respectively. Finally, the average respiratory rates of the horses before and after training exercise were 39.7 ± 3.0 breaths/minute and 101.2 ± 0.5 breaths/minute, respectively.

AbstractThe aim of this study was to examine the influence of an experienced rider and a novice rider on the stride kinematics of experienced riding horses. SVHS video recordings (50 Hz) were made of ten experienced riding horses jumping a 1.05 m-high vertical fence. The horses were randomly assigned to jump the fence under two experimental conditions: ridden by an experienced rider and ridden by a novice rider. Three trials for each ridden condition were analysed, and the effects of the rider type on four kinematic variables were examined using a repeated measures ANOVA. No significant differences were found between the riders for velocity and stride length during the approach, or for the take-off and landing distances from the fence. The results suggest that the rider's body position and body movement had no effect on the horse's jumping kinematics as measured in this study, and that each horse jumped the fence in its own manner, regardless of what the rider was doing. This is contrary to the current belief that a horse's jumping technique is strongly influenced by the rider. These findings have relevance for both horses and riders, in that if an experienced horse does not respond to a rider's instructions as expected, then the implications for training of the horse and the rider are considerable.

This study aimed to perform a comparative analysis of the horses’ heart rate parameters and locomotor activity in a herd or isolation, with or without the company of goats. Twenty horses were tested in a paddock, accompanied (or not) by three goats. The experiment comprised four tests (a control test of a herd of horses without goats, a horse isolation test without goats, a test of a herd of horses with goats and a test of an isolated horse with goats). The horse’s locomotor behavior, and the HR, RR, rMSSD, LF, HF, and LF/HF were recorded. The data analysis included a 15-min rest, procedural and recovery HR/HRV periods, and a 5-min period at the beginning of the test. The duration of the horses standing in the company of goats increased significantly. The rMSSD parameter was the significantly lowest in the test of a herd of horses with goats. The company of goats in a paddock does not eliminate the emotional effects of the phenomenon. However, the locomotor behavior decreases. Goats in a paddock can provide a positive distraction for horses in a herd as a decrease in emotional excitability can be regarded as having a relaxing impact on a different animal species.

Texto completo da fonteResumo:
Regulation EC 1/2005 has stricter rules for transportation of unbroken (untamed) vs. broken (tamed) horses, but does not provide adequate tools for their identification. This study aimed to develop and validate such a tool. A behavioural test (Broken/Unbroken Test (BUT)) based on approaching, haltering, and leading was applied to 100 horses. Physiological and additional behavioural data were also collected, and the horses’ status (broken/unbroken) was assessed by the expert who administered the BUT. Each horse’s behaviour during the BUT was scored by four trained observers blinded to the horse’s history. The BUT score showed excellent inter-observer, intra-observer, and test–retest reliability (all intraclass correlation coefficients (ICCs) > 0.75). It was also negatively associated with respiratory rate, avoidance distance, and time needed to approach, halter, and lead the horse (p < 0.05 for all). The optimal BUT score cut-off for discrimination between broken and unbroken horses (gold standard: expert judgment) showed 97.8% sensitivity and 97.3% specificity. There was almost perfect agreement between BUT-based and expert classification of horses (ICC = 0.940). These findings confirm the BUT’s construct and criterion validity. The BUT could provide officials with a feasible, reliable, and valid tool to identify a horse’s broken/unbroken status and, consequently, direct stakeholders towards correct transport procedures.

Inadequate management conditions can impair the welfare of captive-bred horses. Understanding individuals’ viewpoints and the factors influencing their decisions about adopting or avoiding certain practices may provide insights into their motivations and decision-making processes. This is particularly relevant in the equestrian community, where equine practitioners and enthusiasts often engage in harmful practices. We explored the beliefs, knowledge, and attitudes of equine practitioners and enthusiasts about horse welfare and the barriers that prevent them from employing better management practices that are essential to promoting horses’ welfare. The study consisted of in-depth semi-structured interviews conducted in person with 31 individuals directly involved in the equestrian environment in Brazil. Responses were analyzed through thematic analysis with a data-driven deductive approach. Participants’ beliefs, knowledge and attitudes to horse welfare were divided into three themes. The first theme, “Let the horse be a horse”, captured participants’ perceptions about how physical and mental aspects related to the nature and welfare of horses. The second theme, “Everyone does it like that”, includes the social norms that influence decisions about the practices that impact on the welfare of the horses. The third theme, “Beyond utopia: how and why horses are managed the way they are”, covered barriers that participants perceived as impediments to the use of best practices for the welfare of horses. While participants demonstrated awareness of welfare issues and acknowledged factors that negatively impact horses, there was a notable discrepancy between this knowledge and the implementation of improved management practices. This could be explained by several perceived barriers to implementing management practices that could enhance horse welfare, including lack of financial resources, limited physical space, shortage of qualified labor, time constraints, inadequate tools, and insufficient knowledge. Additionally, we identified deeply rooted social norms within the equestrian community and culturally established practices that limit approaches to horse welfare. Participants underscored the influence of these norms and different interpretations of “letting the horse be a horse” based on the horse’s value and purpose. Concerning low-value horses, the primary justifications for stall housing and concentrated feeding were linked to elevated costs involved in spatial demands and labor; in contrast, for high-value horses used in performance and aesthetics, the arguments shifted to potential benefits to the horses’ well-being. From an ethical perspective, ideally, individuals should refrain from owning horses if they cannot ensure the animals’ welfare. Additionally, if the equestrian community neglects public attitudes towards animal welfare, it risks eroding its social license.

Texto completo da fonteResumo:
Equine-assisted therapies are becoming increasingly popular for addressing physical and psychological disabilities in clients. The role of the horse’s welfare in equine-assisted service receives increasing attention in research. Several studies have shown that horses are able to perceive human emotions and respond to human stress responses. However, no research has yet looked at the other side of the coin—whether and how humans perceive and react to equine stress levels during equine-assisted services. To fill this gap in the research, we employed a within-subjects design, in which horse-naïve participants had a standardized interaction with both an experimentally stressed horse and an experimentally relaxed horse. We assessed physiological indicators of stress (heart rate, heart rate variability, and salivary cortisol) in participants and horses, as well as psychological indicators of stress (state anxiety and positive and negative affect) in participants. Although our stress and relaxation manipulations were successful (indicated by horses’ physiological indicators of stress), we did not find any difference in the participants’ physiological or psychological indicators of stress between the interaction with a stressed and the interaction with a relaxed horse. Together with results from previous studies, this suggests that humans cannot intuitively recognize the (physiological) stress level of horses, which has important implications for effective communication and bonding between humans and horses and for the safety of equine activities.

Texto completo da fonteResumo:
The Equine Behaviour Assessment and Research Questionnaire (E-BARQ) was developed to obtain quantitative data on the domestic equine triad: training, management and behaviour. It can be taken repeatedly, thus collecting longitudinal data to enable evaluation of how changes in a horse’s training and management are reflected in that horse’s behaviour over time and how these changes can impact horse welfare in the longer term. Questionnaire validation and reliability were tested by determining (a) whether an owner’s subjective ratings of their horse’s problematic behaviours or undesirable temperament traits were reflected in the questionnaire scores obtained for that horse (construct validity), (b) whether two respondents, equally familiar with a particular horse, reported comparable scores for that horse through the questionnaire (inter-rater reliability), and (c) whether the same respondent, scoring the same horse after a known interval of time, recorded similar responses (intra-rater reliability). Construct validity testing of 1923 responses showed significant alignment between owners’ reported experience of focal horses’ behaviour and those horses’ E-BARQ scores, with scores varying from 1.13 to 1.34 for ridden horse behaviour (all p < 0.001) and from 1.06 to 1.43 for non-ridden horse behaviour (all p < 0.001). Inter-rater reliability testing of ten horse–rider pairs revealed that 203 of the 215 question items were significantly aligned (p < 0.001) when tested by two independent raters. Of the remaining 19 items, four had fair alignment (ĸ = 0.174–0.316; p = 0.281) and ten items, largely related to whether the horse shows behavioural signs related to anxiety when taken away from home, did not align (ĸ = 0; p = 1). Intra-rater reliability tests showed that the responses significantly aligned on all 215 question items tested (p < 0.001). The results of these tests confirmed the construct validity and reliability of E-BARQ as a standardised behavioural assessment tool for horses.

: The Jinjiang horse is a unique Chinese indigenous horse breed distributed in the southern coastal areas, but the ancestry of Jinjiang horses is not well understood. Here, we used Equine SNP70 Bead Array technology to genotype 301 horses representing 10 Chinese indigenous horse breeds, and we integrated the published genotyped data of 352 individuals from 14 foreign horse breeds to study the relationships between Jinjiang horses and horse breeds from around the world. Principal component analysis (PCA), linkage disequilibrium (LD), runs of homozygosity (ROH) analysis, and ancestry estimating methods were conducted to study the population relationships and the ancestral sources and genetic structure of Jinjiang horses. The results showed that there is no close relationship between foreign horse breeds and Jinjiang horses, and Jinjiang horses shared a similar genetic background with Baise horses. TreeMix analysis revealed that there was gene flow from Chakouyi horses to Jinjiang horses. The ancestry analysis showed that Baise horses and Chakouyi horses are the most closely related ancestors of Jinjiang horses. In conclusion, our results showed that Jinjiang horses have a native origin and that Baise horses and Chakouyi horses were key ancestral sources of Jinjiang horses. The study also suggested that ancient trade activities and the migration of human beings had important effects on indigenous horse breeds in China.

Texto completo da fonteResumo:
Horses are herbivores and are designed to eat a diet high in fibre and low in starch, obtained through freedom of movement to select and forage from a diverse range of plants in the company of other horses. Forage fed to domesticated horses is often provided in various devices designed to replicate more natural feeding patterns, but can result in frustration behaviours even though horses are adept at learning to manipulate such devices to surmount feeding challenges. Because domesticated horses are often required to perform in a range of spheres, which in turn requires higher energy output, many horses have their fibre rations restricted in favour of feeding high-starch substrates. This can lead to significant changes in the microbial environment of the gut, which compromises gastrointestinal health and can cause a range of undesirable behaviours. Diet-related disorders such as gastric ulcers are commonly seen when restricting forage rations and/or overfeeding starch in the horse, and behavioural consequences include frustration-related behaviours, aggression and oral and locomotory stereotypies, all of which compromise the horse's welfare. Meeting the behavioural needs of the horse by giving them agency to access the 3 Fs – friends, forage and freedom – is inextricably linked with their natural feeding behaviour. It is fundamental to ensure that horses are provided with the opportunity for positive feeding experiences to improve both physical and mental welfare.

Texto completo da fonteResumo:
One of the key welfare concerns for horses in the United Kingdom is lack of recognition of fear in horses. This study aimed to gain an understanding of how well horse care givers recognise fear and/or anxiety in horses by interviewing equine behaviourists (who interact with large numbers of horse care givers and talk to them about this topic routinely). The experiences of Animal Behaviour and Training Council (ABTC)-registered equine behaviourists working with horse caregivers were examined, including the ability of clients to recognise fear and/or anxiety in horses, how clients respond when discussing fear as the reason for their horse’s behaviour, and what explanations the participants use to explain fear and anxiety. Semi-structured interviews were conducted with nine participants and analysed using thematic analysis before being written up to reflect the discussion points. When asked how well horse caregivers recognise fear and/or anxiety in horses, three key response themes emerged: caregivers are extremely poor at recognizing fear and anxiety in horses; some clients do recognise behavioural signs indicating fear and/or anxiety but only the overt signs (e.g., rearing, running away) rather than the more subtle signs (e.g., tension in face, subtle avoidance behaviours such as a hesitant gait); and fear and/or anxiety behaviour is often misinterpreted or mislabelled. These key themes recurred throughout several other interview questions. This study has provided initial insights into the lack of recognition of fear and anxiety of horses by their caregivers in the United Kingdom as well as tried and tested approaches to conversations to change this. Such synthesis of experience and techniques across the equine behaviour sector, together with the information gained regarding perception of equine caregivers, could be a valuable approach to improve the effectiveness of behaviour consultations and welfare initiatives.

Texto completo da fonteResumo:
The presence of horses in archaeological sites across North America is often noted in research as an indicator of European contact. Fewer studies, however, have considered how Indigenous peoples incorporated horses as an intrinsic aspect of their lives. Research that considers Indigenous peoples’ relationships with horses typically focuses on Southern Plains groups and does not feature Northern Plains communities as a central aspect. Looking specifically at one Northern Great Plains Indigenous people, this paper analyzes how Blackfoot lifeways were altered as a result of the protohistoric (seventeenth to eighteenth century) reintroduction of the horse. Blackfoot lives were transformed as their relationship with the land evolved, economic systems reformed, and trade, religion, and war became centered around the horse. Almost all Blackfoot people would have felt the effects of the horse’s introduction, however not necessarily equally as these changes caused a shift in hierarchy. These impacts and changes on lifeways are evidenced by European historical accounts, Indigenous oral histories, and the archaeological record. Examining the relationship that the Blackfoot formed with horses demonstrates the significant influence that animals can have over people’s lives. Horses’ introduction to Blackfoot peoples proved to cause significant changes in the ways many conducted their lives, such as through the establishment of nomadic pastoralism and trade routes centered around the horse. This paper additionally calls for further research into the continued relationship between the Blackfoot peoples and the horse.

The aim of the study was to assess whether observations of a horse’s reactions during everyday activities can be used to predict its behaviour during riding. The study was conducted on 60 horses of the Malopolski breed, aged 5 to 15 years. The horses were kept in three riding stables, in a box system. The data were obtained from an interview conducted with a person responsible for the daily grooming and handling of the horses. Observations covered at least half a year of daily contact with the horse. The horses’ behaviour was analysed before feeding, during preparation for riding, and during riding. The research shows that aggressive behaviours before feeding may be a marker of inappropriate reactions before and during recreational riding. Initial activities preparing the horse, i.e. approaching the animal, grooming, bridling and saddling, can be used as a ‘test’ to evaluate and predict the quality of the ride. Problems with these procedures also suggest significant problems during riding. The behaviour of the animal before feeding and during preparations for riding should be considered an important indicator of riding safety and comfort.

Objective To determine whether horses in New York should be vaccinated against equine monocytic ehrlichiosis (EME). Design Decision-tree analyses of data from a cross-sectional study and a case-control study. Sample Population Horses in New York. Procedure Annual expected monetary loss per horse attributable to EME was calculated for vaccinated and nonvaccinated horses in New York. Because risk of being seropositive was dependent on county in which the horse was located, farm elevation, and use of each horse, decision-tree analyses were stratified by these factors. Results Annual expected monetary loss per horse attributable to EME for horses vaccinated by veterinarians ranged from $21 to $21.83/horse/y; for horses vaccinated by owners ranged from $10 to $10.83/horse/y; and for nonvaccinated horses ranged from $0 to $4.03/horse/y. Assuming 78% of vaccinated horses were protected and mean losses associated with EME included costs for horses that died, annual incidence density at which expected monetary loss for vaccinated horses was equal to that for nonvaccinated horses was 12 cases/1,000 horses/y and 25 cases/1,000 horses/y for horses vaccinated by owners or by veterinarians, respectively. Clinical Implications Annual vaccination minimizes monetary losses attributable to EME only when the annual incidence density exceeds 12 to 25 cases/1,000 horses/y. In New York, expected monetary losses are minimized when horses are not vaccinated because of the low annual incidence density in most regions. (J Am Vet Med Assoc 1996;208: 1290–1294)

Horse colour is important. People chose horses for their colour pattern diversity, according to archaeological investigations and biological evidence. Horses were generally dark coloured before domestication, according to molecular testing. After domestication, the genes for white patterns and dilutions appeared. The appearance of their horses, as well as their competence and willingness to work, must have been important to early people. In many cases, the genes that impact coat colour patterns in one species also influence coat colour patterns in another. In horses, humans, cattle, dogs, and other species, the MC1R gene encodes the alleles for red and black of the Extension locus. White spotting is caused by mutations in the KIT gene in horses (tobiano, roan, sabino, dominant white), mice, and humans. Because of its similarity to a white hair gene seen in humans with Hirschprung's illness, the gene for overo in horses was discovered. The genes that impact coat colour patterns in one species generally play a similar role in another, according to molecular studies. It came as no surprise. Earlier geneticists claimed that coat colours in horses were caused by the action of genes similar to those observed in other species based solely on phenotype. This is a crucial lesson for genetic studies: we can apply what we have learned from other species to our own. All in all, the study of coat colour variations in the horse is a study of the horse's nature.

Traits such as shape, size, and color often influence the economic and sentimental value of a horse. Around the world, horses are bred and prized for the colors and markings that make their unique coat patterns stand out from the crowd. The underlying genetic mechanisms determining the color of a horse’s coat can vary greatly in their complexity. For example, only two genetic markers are used to determine a horse’s base coat color, whereas over 50 genetic variations have been discovered to cause white patterning in horses. Some of these white-causing mutations are benign and beautiful, while others have a notable impact on horse health. Negative effects range from slightly more innocuous defects, like deafness, to more pernicious defects, such as the lethal developmental defect incurred when a horse inherits two copies of the Lethal White Overo allele. In this review, we explore, in detail, the etiology of white spotting and its overall effect on the domestic horse to Spot the Pattern of these beautiful (and sometimes dangerous) white mutations.

Selective breeding is in vogue since centuries to improve horse’ breed. It aims at production of horses with special performance and bodily characteristics. It is a complex, costly and time-consuming occupation. But the characteristics of horses depends upon market demands. Many a times a horse, which possesses planned kineto, behavior, exterior characteristics, is not in demand anymore. For many years we performed horse “homeopathic correction†studies at ‘Griffon’ Stud Farm and Horse Club on the basis of A.A. Komissarenko’s theoretical developments. We have established that not only physical characteristics of studs are inherited, but also their psychic traits, which fit into a certain constitutional type of the stud. Among such different types it is possible to identify both harmonious and disharmonious type of animals. It has been established the homeopathic remedy regimen depends on the age of an animal. In our experience, efficient homeopathic correction should be performed once in three months during the entire life-time of a horse, to maintain their bodily and psychic characters.
It is advisable to differentiate the constitutional characteristics of growing horses before fence training, as it may make it easier for the horse to grow and mature. In this case young horses attain good standard, have good height and psychic and physical characteristics.
At the farm we performed homeopathic correction of pregnant animals once in the eight month of pregnancy that is at three months before colt delivery. Four colts were born, which were rated as top grade on the zootechnic scale of All-Russia’s Horse-breeding Research Institute (VNIIKВ). The evaluation is based on the animal activity at different times, during the first three years of the life.
In our observation, colts born after homeopathic correction in the pregnancy period present better exterior and behavioural characteristics than others in their ancestor line.
The outcome of our research is the conclusion that in horse breeding it makes sense to have early homeopathic correction. It improves animal’s performance, the rapport between horses and men and ensures horse’s career success.
Achievements in production of impeccable growing horses were highly appreciated by Trakehner Union in Russia, and the Griffon Stud Farm became a full-fledged member of the Union in 2015.
Utilization of homeopathy resources allows advance of zootechnic industry, as well as prompt response to market demand; the earlier such work begins, the more efficient and cost-effective it becomes.

Since interest in equine manual therapy and rehabilitation is constantly growing, the need for quantification of the horse’s postural response to used alternative therapy has increased. This study implemented geometric morphometrics (GM) for a dorsal profile comparison between the horse groups. The dorsal profile was represented by the centroid size and the centroid shape. The horse groups were defined using four classifiers: horse’s age, height at the withers, time lap in the massage session, and technique of the massage (dorsal, ventral, and dorso–ventral). Out of a total of 900 photographs of 20 horses, 180 photos were analyzed using GM, including thirty landmarks. Variation of the principal components (PCs) representing consecutive dorsal profiles were reported for the first three PSs as 59.50% for PC1, 14.36% for PC2, and 9.01% for PC3. The dorsal profiles differed depending on the classifier ‘height’ in terms of centroid size (p < 0.0001) as well as classifier ‘time’ (p < 0.0001) and classifier ‘technique’ (p < 0.0001) in terms of centroid shape, but not depending on the classifier ‘age’ (p > 0.05). GM allows visualizing the differences in the horses’ posture resulting from the selected manual rehabilitation techniques. The quantification of the horse’s body posture in the studied protocol indicates horses’ body posture after being warmed-up and massaged using the dorso–ventral technique is the most desirable.

Texto completo da fonteResumo:
Feral horses, also known as brumbies, are widely distributed across Australia with some populations being managed largely by human intervention. Rehoming of suitable feral horses following passive trapping has wide community acceptance as a management tool. However, there is little information about the number and relative economic value of feral horses compared with cohorts in the riding horse market. We examined 15,404 advertisements of horses for sale in 53 editions of Horse Deals, published from February 2017 to July 2022. Despite the considerable media attention and public scrutiny surrounding feral horse management, rehomed feral horses represented only a tiny fraction of the horse market in the current study. Of the 15,404 advertisements examined, only 128 (0.0083%) were for feral horses. We recorded phrases used to describe behavioural characteristics and other variables. The following variables were found to be not independent: Ridden Status, Height, Age, Sex, Colour, and Warning terms/more work. Using descriptive statistics to describe basic features of the data, the average price for feral horses ($1408) was lower than that for domestic horses ($1790) with the maximum price for a domestic horse being nearly twice the maximum for a feral horse. Univariate analysis showed feral horses were over-represented among “Unbroken” horses and underrepresented among “Ridden”, “Broodmare” and “Harness” horses compared with domestic bred horses (p < 0.001). Feral horses appeared over-represented at shorter heights, among younger age groups (3 years or younger and 3.1 to 6 years) (p < 0.001) and in the dilute colour category (p = 0.008). The multivariable mixed model on price revealed that for domestic horses, the highest estimated marginal mean price averaged across the colour categories was for ridden horses aged 6.1–10-year-old at $1657.04 (95% CI $1320.56–$2074.66). In contrast, for feral horses, the multivariable mixed model demonstrated the similar highest estimated marginal mean averaged was for green broken 3–6-year-old horses that have undergone foundation training under saddle at $2526.97 (95% CI $1505.63–$4208.27). Australian feral horses were valued differently tfromsimilar domestic horses in the recreational riding horse market and further research is warranted to determine appropriate target markets and boost the sustainability of rehoming as a feral horse management tool.

Limited research has assessed the “human dimension” of horse care. The aims of this study were to (1) understand horse owner attitudes toward horse welfare when kept outdoors versus indoors and in groups versus individually, (2) compare horse owner attitudes toward horse welfare with the ways in which they house their horses, and (3) explore horse owner reasons for and challenges with their horses’ housing. Seventy-six horse owners in Prince Edward Island, Canada completed a questionnaire. Non-parametric tests and quantitative content analysis were used for data analysis. Consistent with the way horses were kept, most (82–96%) owners agreed that horses’ physical health, mental well-being, and natural living were better when kept outdoors and in groups. Fewer (64–68%) participants agreed that the horses’ standard of care was better when kept outdoors or in groups. Results show associations between owners whose attitudes suggest indoor and/or individual housing is better for horse welfare and keeping their horses indoors part-time and/or individually. Two overarching themes were developed from owners’ responses regarding their reasons and challenges related to the ways in which horses were housed: horse-centered and owner-centered care. The results indicate that horse owners’ choices about their horses’ housing correspond to beliefs about improved horse welfare.

Texto completo da fonteResumo:
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.

Texto completo da fonteResumo:
The structure and changes occurring to horses’ teeth during ontogeny are not only used to assess the degree of somatic maturity but also the development of universal patterns and is therefore used to determine the age of horses. Research shows that methods of assessing the age of horses based on the appearance of teeth tend to suffer from relatively large errors. This is probably influenced by the results of intensive selection and being kept in living conditions that differ substantially from their natural environment. This study aimed to assess the suitability of selected features of the incisors to determine the age of Icelandic horses. One hundred and twenty-six Icelandic horses (78 mares and 48 stallions) of different ages (range: 0–24 years; groups: 0–2 years, >2–5 years, >5–11 years, and >11 years) were examined by an experienced horse person who was blinded to the actual age of the horse and did not know which age group horses were in. Age was determined by the inspection of each horse’s teeth and was compared to the actual age of the horse recorded in the breeding documentation, and the percentage of mistakes made regarding the age group was calculated. The estimated age did not match the real age in 36.5% of the horses. The age was more often underestimated (19.0%) by, on average, 0.9 ± 1.0 years than overestimated (17.5%) by, on average, 1.3 ± 1.4 years. Within age groups, the least number of errors in determining age were made in young horses aged 0–2 years, when the eruption and growing of the deciduous incisors and the disappearance of the cups was considered. The average percentage of errors in this group (2.1%) was significantly lower (p < 0.01) than for older horses, whose age was estimated based on the exchange of deciduous to permanent teeth (55.8%), disappearance of the cups (68.0%), and shape changes on the grinding surface (40.0%). Significantly more frequent underestimation of age based on replacing deciduous for permanent incisors and significantly more frequent overestimation of age on the basis of the disappearance of the cup may indicate that Icelandic horses up to 5 years of age are characterized by a slower rate of growth than horses of other breeds, especially warmblood horses. These results suggest that patterns used to determine the real age of horses based on changes occurring on the incisors should be modified in order to consider the specificity of the course of growth and maturation processes of horses of various types and breeds.

Texto completo da fonteResumo:
A treadmill is an important tool in the equine analysis of gait, lameness, and hoof balance, as well as for the evaluation of horse rehabilitation or poor performance including dynamic endoscopy. Before all of these uses, horses have to be habituated to a treadmill locomotion. We used principal component analysis to evaluate the relationship between aspects of the horse’s temperament and emotional response, and progress in the behavioral habituation to a treadmill. Fourteen horses were tested, by the same familiar handler, using the novel object test, the handling test, and both positive and negative emotional response tests. Then, four stages of gradual habituation of the first work on a treadmill were conducted. Each time, the horse’s behavior was filmed. Data obtained from ethograms and heart rate measurements were tested. Four principal components were identified in examined horses: “Flightiness”, “Freeziness”, “Curiosity”, and “Timidity”. Flightiness was connected with nervousness, agitation by new objects, and easy excitability, and gradually decreased of features during habituation. Timidity was associated with a lack of courage and stress in new situations, and those features strongly increased when the treadmill was introduced. Freeziness and Curiosity features showed strong stability throughout the whole habituation. The results of this study provide evidence for a connection between temperament, emotional response, and habituation process in a horse.

Current evidence of how human sex-related differences in riders and handlers may influence horse behaviour is limited. The Equine Behaviour Assessment and Research Questionnaire (E-BARQ) was used to collect demographic data on riders and handlers (n = 1420) and behavioural data on their horses. It includes demographic items about the sex of the respondent and how frequently the horse has been ridden or handled by male and female humans. The questionnaire then gathers observations on the horse’s behaviour on the ground and under saddle or when driven. Using E-BARQ’s battery of 97 questions, the current study showed differences in ridden and non-ridden horse behaviour that were related to the sex of the rider or handler. Data were evaluated using multivariate analysis and revealed that horses handled by male humans were significantly more difficult to catch (t-value = −3.11; p = 0.002) and significantly more defensive when approached (t-value = −2.104; p = 0.035), but significantly less likely to pull on the reins/brace the neck or toss their head (t-value 1.980; p = 0.048) than horses handled more frequently by female humans. The differences found between male and female horse handlers suggest that sex is an important factor to consider when understanding equine behaviour. Our study explored reported differences in confidence, handling and working compliance and touch sensitivity among horses ridden and handled by male and female humans and suggested further research into how these differences are gendered.

Texto completo da fonteResumo:
It is logical to assume that horses with multiple riders encounter variation in application of training cues. When training cues are inconsistent, we expect to see a decrease in trained responses or an increase in conflict behaviours. This study investigated the relationship between the number of people that regularly ride or handle a horse and the horse’s response to operant cues. Data on 1819 equids were obtained from the Equine Behavior Assessment and Research Questionnaire (E-BARQ), an online global survey of horse owners and caregivers. Three mutually independent indices (acceleration, deceleration, and responsiveness) were derived from a parallel analysis of E-BARQ items related to acceleration and deceleration cues. These indices were then subjected to multivariable modelling against a range of dependent variables including horse and human demographics, horse management, and the number of riders or handlers. The number of riders or handlers was a significant predictor for two out of three indices. As the number of riders or handlers increased, horses were more difficult to accelerate (regression coefficient = 0.0148 ± 0.0071; p = 0.0366) and less difficult to decelerate (regression coefficient = −0.017 ± 0.008; p = 0.030) than those with fewer riders or handlers. These findings suggest that horses’ responses to rein tension cues are more persistent than their responses to leg pressure or whip cues. Alternatively, horses with these responses may be actively selected for multiple rider roles. Longitudinal studies of this sort should reveal how the number of riders or handlers affects horse behaviour and could lead to safer and more humane equestrian practices.

Texto completo da fonteResumo:
A plasma cortisol measurement and behavioral assessment of five horses was performed, to determine whether there was a correlation between plasma cortisol and their reactivity. A subjective emotionality survey for each horse was completed by the horse's owners and an objective novel stimulus reactivity test was performed. The horses reactions were used to calculate reactivity scores on a reactivity assessment sheet we specially designed. Concentration of plasma cortisol was also measured and reactions to the blood sampling were quantified. Associations were made between those different parameters. All five horses appeared to be hypo reactive and their cortisol levels were also very low. Behavioral assessed reactivity seemed to correlate directly with the plasma cortisol, all values showing a marked hypo reactivity in all horses. The data obtained provided evidence that low plasma cortisol is a good marker of reactivity in hypo reactive horses and also that the designed sheets for the assessment of objective and subjective reactivity may be used, in correlation with plasma cortisol as an assessment tool in the current practice.

Since ancient times in Uzbekistan, special attention has been paid to horse breeding. We can see this in dastans and traditions, where poets and bakhshis sang about mythical horses. And most importantly, the horse was very much appreciated as a companion of a horse. As in other regions of the republic, special attention was paid to the development of horse breeding in the Surkhan oasis. Several breeds of horses were bred in the oasis, they were called ‘adobe’, ‘jiyran’, ‘turik’, ‘buz’ and others by color. Uzbeks mainly bred ‘Karabair’, ‘Lakay’, ‘Turkman’, and sometimes Arab ones. For breeding local breeds of horses ‘Karabair’ were used breeds of Turkmen, Arab and Mongolian horses. By breeding horses such breeds of ‘Karabair’ horses as ‘Uzbek’, ‘Miyenkul’, ‘Urgut’ and others were bred. Also, horses were named for their age. A newborn horse was called a ‘kulun’, up to one year a foal, from a year and a half to two years a strigunok, a two-three year old foal, a third year a gunan, a three-four year old dunan, a male after four years a stallion, a female mare. In the Surkhan oasis, Turkmen horses were widely used as a vehicle, they participated in horse racing, racing and kupkari (equestrian competition in which the participants of the competition rip out goat carcass from each other). Responsible for the conservation and reproduction of horse breeds were men. They promptly gave horses food, took them for a walk. The horses that took part in the races, kupkari were raised according to special methods and customs. Such horses were fed from spring to late autumn, with the arrival of autumn they were walked and prepared for competitions. Horses were considered not only a vehicle; they were the most expensive and valuable commodity. At that time, the best horses were estimated from 400 to 600 rubles, and Turkmen horses to 1000 rubles. In a word, horses were not only expensive goods; they were considered the best friend and helper of a horseman.

Summary Records of 6 horses with pericarditis were reviewed. Septic pericarditis was suspected in all horses, based on historic and clinical findings. In horses 1, 2, and 4, cytologic examination of the pericardial effusion revealed acute inflammation with severe neutrophil degeneration. In horses 3 and 5, cytologic examination of pericardial fluid revealed subacute inflammation with degenerated neutrophils, and in horse 6, chronic active inflammation, with well preserved neutrophils. In horses 1 and 3, bacteria were identified on cytologic examination of pericardial fluid. Results of microbiologic cultures of pericardial fluid were positive in horse 3. All horses were treated with broad-spectrum antibiotics. An indwelling pericardial catheter was used to lavage and directly administer antibiotics into the pericardial sac. Horses 1, 4, 5, and 6 survived, horse 2 died of unrelated causes, and horse 3 was euthanatized at the owner's request. Surviving horses returned to athletic performance.

The influence of a horse’s appearance on health, sentimental and monetary value has driven the desire to understand the etiology of coat color. White markings on the coat define inclusion for multiple horse breeds, but they may disqualify a horse from registration in other breeds. In domesticated horses (Equus caballus), 35 KIT alleles are associated with or cause depigmentation and white spotting. It is a common misconception among the general public that a horse can possess only two KIT variants. To correct this misconception, we used BEAGLE 5.4-phased NGS data to identify 15 haplotypes possessing two or more KIT variants previously associated with depigmentation phenotypes. We sourced photos for 161 horses comprising 12 compound genotypes with three or more KIT variants and employed a standardized method to grade depigmentation, yielding average white scores for each unique compound genotype. We found that 7 of the 12 multi-variant haplotypes resulted in significantly more depigmentation relative to the single-variant haplotypes (ANOVA). It is clear horses can possess more than two KIT variants, and future work aims to document phenotypic variations for each compound genotype.

Equestrian sport is considered a high-risk environment for equine injury. Due to the close bond between horse and rider, it could be theorised that riders may be impacted psychologically by their horses’ injuries, as seen in athletic pairs and with companion animal ownership. The extensive time commitment and responsibility of care within equestrian sport means that horse riders’ day-to-day life is impacted in a way not seen in other sporting or leisure environments, thus providing a unique opportunity to investigate the psychological responses of riders to their horse’s injury. The aims of this study were to investigate the psychological responses that amateur riders experienced when their horses were injured. 308 amateur horse riders (16 male and 292 female, median age 25-30 category) completed the Psychological Response to Sport Injury Inventory (19-item) (PRSII) and questions regarding demographics, investment in equestrian sport, the horse’s injury and the length of rehabilitation. Devastation was significantly affected by the weekly time investment of riders (H(3)=8.255, P=0.041) and the length of ownership prior to the injury (H(2)=7.690, P=0.021). ‘Devastation’, ‘feeling cheated’, ‘restlessness’ and ‘isolation’ were all significantly affected by the length of rehabilitation for the horse (H(7)=70.825, P=0.000, H(7)=37.799, P=0.000, H(7)=37.799, P=0.004, and H(7)=27.486, P=0.000, respectively). These findings suggest that amateur horse riders are at risk of psychological distress when their horse becomes injured. Whilst the industry has developed strategies to support owners following euthanasia which are already in place, psychological support following horse injury may be necessary to buffer psychological ‘devastation’ within amateur horse owners.

Objective To analyze medical records and identify factors that veterinarians can use to prevent pulmonary aspergillosis in horses or that would enable them to diagnose it as early as possible. Design Retrospective study. Animals 29 horses. Procedure Medical records were reviewed for horses with pulmonary aspergillosis diagnosed on the basis of characteristic postmortem findings. Information on history, clinical signs, disease progression, and postmortem findings was obtained. Results 25 of 29 (86.2%) horses had primary (n = 20) or secondary (5) disease compatible with loss of integrity of the gastrointestinal (GI) tract. The remaining 4 horses had a non-GI tract disorder; only 1 of these 4 had clinical signs associated with the respiratory tract (ie, pleuropneumonia). Although 22 (75.9%) horses had various signs of respiratory tract disorders, an antemortem diagnosis of Aspergillus pneumonia was made in only 1 horse and was suspected in only 1 other. Fungal organisms were seen histologically in tissues other than the lung in 12 (41.4%) horses. Clinical Implications Horses with enteritis, colitis, typhlitis, or other diseases of the GI tract that result in mucosal compromise, and horses with clinical signs of respiratory tract disease, particularly if the horse's condition is unresponsive to treatment with antimicrobial agents, should be considered at high risk of having pulmonary aspergillosis. Immunosuppression from debilitating disease may also predispose horses to aspergillosis. Because invasive pulmonary aspergillosis can be difficult to diagnose, clinicians should be aware of clinical and epidemiologic settings in which this disease would develop.

In horse breeding, it is important to introduce affordable methods for assessing the potential of the horse’s body to perform work of varying severity and in different terrain conditions (altitude, landscape features, type of work). The applicability of the method of dosing the load of working horses in highland conditions has been established on the basis of the value of the horse’s body weight calculated using the “heart girth” measurement, but the work should already be classified as heavy at a load weight of 15% of the horse’s body weight. The arterial molecular oxygen saturation of the blood and the pulse rate are sufficient to assess the state of respiratory function and the nature of the involvement of associated systems. The studies carried out on 14 mature working horses and also on 5 young horses used for work in lowland and highland conditions have made it possible to recommend the widespread use of the pulse oximeter for rapid analysis of blood oxygen saturation and pulse rate in order to dose the workload of these animals appropriately. Veterinary examination of horses with abnormal oxygen saturation and pulse pattern detected by the pulse oximeter confirmed the presence of clinical signs and laboratory markers of disorders in the body of a stallion and a repair mare, excluding the use of these animals as working animals. Early detection of inadequate respiratory function in young animals can allow a balanced decision to be made to refuse special training and prevent economic losses.

Texto completo da fonteResumo:
Mosquitoes are pests of horses, but mosquito trap efficacy data, especially the ability of traps to protect horses, are lacking. Studies were conducted to investigate the comparative attraction between traps and horses, increase trap attraction by adding horse odors to the airstream of a trap, determine the spatial distribution of adult mosquitoes, estimate the numbers of mosquitoes feeding on horses, determine the relative attraction of horses to mosquitoes, and estimate the range of mosquitoes’ attraction between two horses. When a horse and a mosquito trap were placed 3.5 m apart, there was a significant reduction in mosquitoes entering the trap. Adding horse odors to the airstream of a trap produced equivocal results because the horse providing the odors influenced the trap catches. Mosquitoes were not evenly distributed across the study site, which emphasized the importance of trap placement. Vacuuming mosquitoes from the horses in different seasons demonstrated that 324 and 359 mosquitoes per hour were feeding during the two studies. Separate analysis of data from the two horses vacuumed simultaneously revealed that one horse attracted twice as many mosquitoes as the other. This caused the results of a study to determine the attraction range of two horses moved from 3.5 to 20.4 m apart to be inconclusive.

It was assumed that a horse with its rider body weight found in the upper limit may negatively impact the horse’s welfare. The objective of this paper was to analyze the differences in body temperature and selected heart rate parameters in horses in response to physical exercise accompanied by various rider’s body weight loads. The study was carried out on 12 leisure, 10–15-year-old warmblood geldings. The horses were ridden by two equally qualified riders whose body weights were about 20% and 10% of the average body weight (BW) of the animals (about 470 kg). Each rider rode each of the 12 horses for 13 min walking and 20 min of trotting. Images of the horse at rest, after physical exercise directly after unsaddling, and during the recovery phase (10 min after unsaddling) were taken with an infrared thermography camera. For analysis, the temperatures of selected body parts were measured on the surface of the head, neck, front, middle, and back (croup) parts of the trunk, forelimb, and hind limb. Immediately after the infrared thermography images were taken, the rectal temperature of the horse was measured. The heart rate parameters were measured at rest for 10 min directly before, during, and 10 min following the end of a training session. A multivariate analysis of variance (ANOVA) for repeated measurements was performed. Statistical significance was accepted for p < 0.05. A rider BW load on a horse of approximately 20% of the horse’s BW led to a substantial increase in the superficial temperatures of the neck, front, middle, and back parts of the trunk in relation to these body parts’ average temperatures when the load was about 10% BW. The head and limb average temperatures were not significantly affected by the load of the exercised horse. A horse’s load above 20% of his body weight, even with little effort, affects changes in surface temperature and the activity of the autonomic nervous system.

In the scientific article “Meanings of war horse colours and epic tradition” the typological similarities of poetic description of heroic epics of Turkic-speaking peoples and Siberia formed in the context of the epic “Manas” are considered. The etymological meanings of war horse colours in the artistic structure of the epic “Manas” are also analysed. The epic “Manas” has brought to our days a whole range of images of horses, starting with fantastic mythological images of horses and ending with realistic ones. Descriptions of the horse’s colours, the peculiarities of its walking and running, its ability to understand not only the master’s orders but also its state of mind occupy a large place in the narrative. Each horse is endowed with a nickname, each is characterised by some qualities peculiar only to it. It is known that different time layers are present in the epic, and from this it is possible to reveal the images of the Tulpar in their stadial evolution, which makes it possible to consider their essence in hyperpolarity. In the epic “Manas” there are more than 150 names of war horses of different colours. The totality of artistic images of war horses depicted in the context of “myth and reality” as endowing them with wings, human speech, and the ability to transform through transformation into werewolves is a real cultural treasure of the epics and a subject of scientific interest of hundreds of researchers. In the process of evolution each national epic preserving the given properties of the archetype, at the same time transformed into the poetic image of horses some specific properties, developing and glorifying some special qualities inherent only to the given epic.

Texto completo da fonteResumo:
Summary Loop colostomy was performed in 10 horses as treatment for grade-III rectal tears (n = 6 horses), small-colon infarction (n = 2 horses), perirectal abscess and stenosis (n = 1 horse), and small-colon stricture (n = 1 horse). In 7 horses, the colostomy was constructed through a single incision low in the left flank, with closure of the incision around the stoma (single-incision technique). In 3 horses, 2 of which had colostomy performed as a standing procedure, the selected segment of small colon was placed from a flank incision into a separate, small incision low in the left flank (double-incision technique). Five horses underwent colostomy reversal (at 18 to 63 days) and 2 of these horses, both with grade-III rectal tears, recovered completely. Of 8 horses that did not survive, 6 died from the primary disease or associated complications. Technical problems associated with colostomy accounted for death of 2 horses. One horse had gastric rupture attributable to suture occlusion of the small intestine after colostomy reversal, and another horse had complications of incisional infection after repair of a peristomal hernia. Small-colon prolapse through the stoma necessitated premature reversal of the colostomy in a horse that was euthanatized because of worsening laminitis. Minor complications of the colostomy procedure were partial stomal dehiscence (n = 4 horses), partial dehiscence of the flank wound after colostomy reversal (n = 2 horses), and small ventral midline hernia after colostomy reversal (n = 1 horse). Loop colostomy may be of benefit to horses with rectal tears, provided it is done soon after the tear occurs. The double-incision technique for loop colostomy is recommended, because it appeared to reduce the risks of peristomal herniation and stomal prolapse. Other recommendations are made to reduce complications of colostomy and facilitate reversal.

Horse breeding in the Republic of Croatia, before its entrance into European Union, is in the transitional period. In the breeding sense, Croatian horse breeding is set according to the model of European countries and is trying to counteract with ?modern horse breeding countries?. Croatian Center for Horse Breeding - Djakovo and Lipik State Stud Farms (CCHB), with the Central register of equidae is, as the head national institution, responsible for running and maintaining national central equidae database (49 registers of horses and 27 registers of breeding types). Croatia has registered total of 21.796 equidae, from which 19.306 animals are horses. Registered horses according to groups make the total proportion of 37% warmblood horses, 59% coldblood horses and 4% ponies. Horse breeders are organized in breeders associations, which form federations of associations referring to separate horse breeds. Currently in Croatia there are four federations of breeders associations (with 43 associations and 11 private stud farms). Those verified breeding organizations are conducting independently breeding programs and fully maintain breeding and selection obligations for horse breeds for which they have approval of the Croatian Ministry. Native breeds in Croatia are Croatian Coldblood, Croatian Posavac and Medjimurje horse (Murinsulaner), while Lipizzan horse is considered as protected breed. Development of horse breeding is considerably supported with national subsidies. Internationally verified breeds which are bred in Croatia are Lipizzan horse, Pure Arabian horses, Thoroughbred, Haflinger and Gidran horses. The horse breeding in Croatia is developing in four different directions. Ecological breeding implies native horse breeds and is spread on the areas of protected nature resorts in Croatia. Croatians are through their history connected to horse breeding, which is even today irreplaceable in traditional cultural manifestations (Djakovacki vezovi, Vinkovacke jeseni, Sinjska alka, etc.), various horse shows and fairs and also in more ?modern? ways through recreation and entertainment. The third direction of development of horse breeding in Croatia is therapeutic riding, which includes 26 associations, over one hundred horses and over one thousand users organized under the Therapeutic Riding Association of Croatia. Sports horse breeding represents fourth direction in Croatian horse breeding. It is formed by four federations: Croatian Trotting Federation (trotting), Croatian Gallop Federation (gallop sport) and Croatian Equestrian Federation (endurance, dressage, military, show jumping, driving). Croatian Equestrian Federation includes 49 equestrian clubs. In the last four years between 455 and 582 competitors and between 495 and 581 horses (for show jumping 45%, dressage 31%, endurance 19%, driving 5% and military) were licensed annually. Croatia achieved noticeable results on the international scene in driving sports and in Paralympics. In all mentioned directions of Croatian horse breeding, the tendency should be directed to achieving higher breeding standards (nutrition, stabling, transport, training) and more rational using of horses. Such breeding and using of horses will lead to top bred horses and successful sport horses. This implies synchronized work through long period of time, respecting institutional and breeding rules.

Texto completo da fonteResumo:
Travellers and Gypsies are recognised ethnic groups in the UK and Ireland. Horse ownership is an important cultural tradition, however, practices associated with poor welfare are often perceived to be linked to these horse owning communities. Despite this, empirical studies on the welfare status of Traveller and Gypsy owned horses are lacking. To determine the welfare status of Traveller and Gypsy owned horses, 104 horses were assessed using a bespoke horse welfare protocol. This protocol assessed animal, resource and management-based measures. In addition, Qualitative Behaviour Assessment (QBA) identified horses’ emotional state. Results indicated that 81% of horses had an optimal body condition score, with no horse recorded as very thin/fat. The absence of limb conditions (95%), ocular (98%) and nasal (93%) discharges were evident in most horses, and 81% of horses responded positively to the voluntary animal approach test. The most commonly observed welfare issues were hoof neglect (27%), with hoof cracks/breakages (19%) being the most prevalent. QBA indicated that positive emotional states were more commonplace than negative. A relationship between QBA and other horse welfare measures was observed, e.g., improved mood was associated with better water availability. This research provides novel data in the under-researched area of the welfare of Traveller and Gypsy owned horses and counters perceptions of a poor welfare state in this group of horses.

Colic is a common and potentially life-threatening condition of horses. Multiple risk factors have been previously identified and it is known that a careful management routine can help reduce colic rates. The British military working horse population represents a unique cohort of horses that are intensively managed with a strict regimen. This retrospective study examined the incidence and mortality rate of colic within this population, as well as the signalment of affected horses, and compared these with the general population. Data for 717 horses over a five-year period (2008–2012) were analysed. Of these, 163 horses (22.7 per cent) experienced 267 colic episodes and 13 horses (1.8 per cent) died because of colic. Recurrent colic was experienced by 35 per cent (57/163) of horses. The incidence of colic was 11.1 episodes per 100 horse-years and of colic-related death was 0.5 deaths per 100 horse-years. Horses purchased from mainland Europe were more likely to suffer from colic (OR 4.6; P<0.001) and from recurrent colic (OR 6.0; P=0.005) than horses purchased from Ireland. Only 3 per cent (8/267) of colic episodes were treated surgically. It was concluded that the incidences of colic and colic-related deaths within the British military working horse population are similar to those of the general horse population.

The objective of the present study was to analyse the numbers and division of horses of undefined breed. At the present time this group is the most numerous in the entire population of horses. Horses of undefined breed do not come under any breeder union which would provide reports about these horses; these horses are only registered and breeders are informed only about their numbers. Our study is the first to deal with the problem of increasing numbers of horses of undefined breed. The database contained 22 211 horses not entered registered in any of the stud books. In the database we filed approved horses born between 1972 and 1 September 2012 and horses registered from 1987. The data were processed in the Excel programme and results were evaluated in graphs. The most frequent horse in this group was the warm-blood type (n = 9 303), pony type (n = 6 285), cold-blooded type (n = 2 663) and unlisted horses (n = 2 278). Since 2001 the number of registered horses of undefined breed has increased. The most numerous dams of horses of undefined breed is the Czech warm-blood with 1 912 offspring; dams of the English Thoroughbred with 552 offspring and mares of the utility Huzule horse with 492 offspring. In the group of registered horses of undefined breed the Czech warm-blood appears in the pedigree of 507 colts and the American Paint Horse in the pedigree of sires of 506 colts. Why the numbers of horses of undefined breed are increasing is the boom of leisure horsemanship and unqualified horse breeding.

Infrared thermography is a painless, non-invasive method that can be used to improve the physiological assessment and health of the horse, and as an alternative, or in combination with other imaging methods and diagnostic procedures. The main advantage of thermography is the detection of subclinical signs of inflammation before the onset of clinical signs of pathology. The aim of this pilot study was to determine the surface body temperature of six clinically healthy horses in indoor conditions. The horses` bodies were laterally scanned on the left and right sides and were divided into the following regions: neck, shoulder, thoracic limb, back, thigh and pelvic limb. The abdominal region of the horses was scanned individually in ventral projection. The average temperature of each region was calculated. An approximately equal thermal symmetry was observed between both sides of the horse’s body.

Twelve clinical cases of cyathostomosis in horses treated at the Equine Clinic University of Veterinary and Pharmaceutical Sciences in Brno, the Czech Republic, between the years 1999 and 2008 are described in this report. Six cases (50%) were hospitalized in the period from 2007 to 2008. Eleven of them were hospitalized in the period from December to March. Only one case was admitted in June, but the clinical signs had appeared for the first time in January. All horses described in these cases were younger than six years of age. Diarrhoea as a predominant clinical sign was present in four horses and colic in four horses. One horse showed both colic and diarrhoea whilst three horses had weight loss and subcutaneous oedema. Metabolic acidosis was found in three horses, eight patients had leucocytosis. Hypoproteinemia was found in four horses, hypoalbuminemia in seven horses, hypokalemia in three horses and increased alkaline phosphatase (ALP) activity in five horses. Seven horses recovered, one horse died and four horses were euthanized.
