Nutrition plays a critical role in equine health. The horse owner and/or manager has a multitude of equine nutrition sources available to them, with preferences for how, and from whom, this information is delivered. Despite this, poor feeding practices continue to negatively affect the health, wellness, and welfare of equids and have a detrimental impact on the environment. The veterinarian is the primary expected source of equine nutrition information; yet, little is known about their recognition and acceptance of such a role. Doubt has arisen concerning the quality and provision of nutrition education within the veterinary curriculum and subsequent continuing education. Moreover, the value equine nutrition education plays in the veterinarian's practice philosophy, and the resulting provision of such in clinical practice, remains under evaluated. This review examines the present state of equine nutrition and how horses are being fed in practice, in the United States. It considers feeding horses from the horse owner's perspective and the expected role the veterinarian plays in such. Last, it goes on to evaluate this expected role from the veterinarian's perspective, examining how current nutrition education and practices may be falling short and offering recommendations for future research. 相似文献

Nutrition is a critical component of equine health. Horse owners' knowledge of nutrition is likely to affect their feeding practices. The aim of this study was to survey feeding practices, dietary supplement use, and knowledge about equine nutrition in New England by surveying a subpopulation of horse owners (67/337 or 19.8%) who brought their horses to the Large Animal Hospital at the Cummings School of Veterinary Medicine at Tufts University between July and September 2008. All owners reported feeding hay, with the majority feeding grass or timothy hay. Most owners (96%) reported feeding a concentrate in addition to hay. Approximately 84% of owners reported including at least one dietary supplement in their horse's daily feeding. The most commonly used supplements were chondroprotectives, electrolytes, and multivitamins. Survey questions designed to assess the owner's knowledge of nutrition suggested that many owners may not have a basic understanding of principles of equine nutrition; less than 50% knew the daily water and hay requirements for a horse, and 69% lacked knowledge about the proper use of concentrates in a diet. Most of the surveyed owners consulted multiple sources of information concerning equine nutrition, including veterinarians (n = 36), trainers (n = 27), feed stores (n = 10), and the internet (n = 7). Although the major source of information was the veterinarian, it appears that the communication between horse owners and their veterinarian about optimal feeding practices could be enhanced. This survey demonstrated areas in the veterinarian–client dialog that need to be addressed when evaluating the health and well-being of the horse. 相似文献

The practice of horse rugging has important implications for horse welfare and performance, but in Australia, rugging practices have not been properly documented. The objective of this study was to obtain an understanding of Australian horse rugging practices. An online survey reviewed the management of 2659 Australian horses over 12 months. Of the reported horses a total of 84.8% were rugged, although most owners (69.5%) indicated that they were unsure whether horses needed to be rugged at all. Rugging was felt by 59.8% of owners to be a requirement for horses in competition. Riding and competition were significantly associated with the use of rugs. Nearly all respondents (89.0%) felt that ‘over-rugging’ was a concern. However, 4.8% of owners would use up to 4 rugs at any one time on their horse and 21.4% of horses were still rugged in temperatures above 20°C in Australia. Many Australian horse owners (42.8%) also believe that horses feel cold if they are not rugged. Anthropomorphism when it comes to rugging horses cannot be justified as the horse has a much wider thermoneutral zone (TNZ) than humans. Australian climate, owner opinions, equestrian discipline and whether a horse is used for riding influence Australian horse rugging practices. However, current practices are based on limited available research and are not necessarily to the benefit of the horse. The major limitation was that the survey likely attracted respondents who are interested in the topic creating a self-selection bias. 相似文献

This study aimed to characterise current practice relating to equine castration in the UK. A questionnaire was posted to all 655 veterinary practices specified to provide veterinary care for horses, or classified as specialist equine practices. Respondents were asked to cite the number of equine castrations performed annually by the practice, describe techniques used for castration, outline anaesthetic/sedative/analgesic drug protocols used and provide details of post-operative medication. There was a 43% response rate to the questionnaire. Considerable variation in techniques and analgesia provision was identified, with the majority of respondents using a number of sedation/anaesthetic protocols rather than a single technique. This characterisation of current practice provides a useful platform from which subsequent investigations into welfare implications of current equine castration techniques can be directed. 相似文献

Reasons for performing study: Significant potential threats to the health and welfare of horses exist in Ireland when supply exceeds demand and the identification system for horses is not yet robust. Objectives: To secure engagement with stakeholder groups and determine their perception of equine welfare in Ireland and encourage the development of inclusive, rather than imposed, policy solutions. Methods: A 3 round, web‐based Policy Delphi incorporating novel vignette methodology was conducted from November 2007–March 2008 to canvass opinion (in both quantitative and qualitative forms) on the perceived most significant equine welfare issues. Vignettes (narratives depicting potential compromise to equine welfare) were employed. Quantitative data were collected in the form of scoring on a 9 point Likert scale with labelled end‐points, qualitative information as text subsequently analysed for themes. Results: All 44 respondents completed all rounds. Major equine welfare issues were identified as welfare of horses during the disposal process and at unregulated gatherings. Assessed quantitatively on a 9 point Likert scale (0 = minimal; 8 = maximal), respondents scored the desirability and feasibility of improving standards, median 8 and 6, respectively, for both issues identified. Basic themes identified in respondents' quotes as reasons to raise equine welfare standards were ideological, protection of animal welfare, safe‐guarding the reputation of the equine industry and safety (of people, horses and environment). Themes for reasons for low standards were societal norms, fiscal pressures, indolence, indifference and ignorance. Themes underpinning potential means for achieving meaningful change (solutions) were legislation, enforcement, education/training, fiscal remedies, increasing awareness and a combination of these. Conclusions: Mechanisms aimed at raising standards must be based on an understanding of motivational drivers for currently low standards. Potential relevance: The challenge is to translate the findings and this heightened awareness into meaningful change to the benefit of horses and those who care for them. 相似文献

Following the first ever equine influenza outbreak in Australia in 2007, a study was conducted involving 200 horse owners and managers to determine their perceptions about effectiveness of biosecurity measures and the factors associated with these perceptions. Face-to-face interviews were conducted with horse owners/managers to obtain information about their perceptions of the effectiveness of biosecurity practices, their sources of information about infection control during the outbreak and their horse industry involvement. Two outcome variables were created from horse owners' responses to a 17-item question on the perceived effectiveness of various recommended equine influenza biosecurity measures: (a) a binary outcome variable (Low/High biosecurity effectiveness) and (b) a continuous outcome variable (the proportion of the 17 measures considered 'very effective'). These outcomes were used in binomial logistic and linear regression analyses, respectively, to determine factors associated with perceptions of biosecurity effectiveness. Variables with a p-value <0.05 in multivariable models were retained in the final models. The majority (83%) of the 200 horse owners and managers interviewed believed that more than half of the recommended equine influenza biosecurity measures were very effective for protecting their horses from equine influenza infection in the event of a future outbreak. Interviewees that were more likely to judge on-farm biosecurity measures as effective were those who received infection control information from a veterinarian during the outbreak, did not experience equine influenza infection in their horses, and those on small acreage premises (homes with horses on site). Greater levels of preparedness for a future equine influenza outbreak and greater interest in information about infection control were associated with a better perception about effectiveness of biosecurity measures. This study identified factors associated with horse owners' and managers' perception of effectiveness of biosecurity measures. These findings should be considered in the design of infection control programs. 相似文献

The number of donkeys and mules throughout the world is stable, and awareness of their use and concern for welfare, pain recognition and treatment are receiving increasing veterinary interest. Therefore, accurate information about anaesthesia and analgesia in donkeys and mules is important to ever more equine practitioners. Since donkeys are physiologically and pharmacologically different from horses, knowledge on species specific aspects of anaesthesia and analgesia are very important. Mules combine elements from both donkey and horse backgrounds, leading to great diversity in size, temperament and body type. Physiologically, they seem to resemble horses more than donkeys. This review highlights the current knowledge on various anaesthetic and analgesic approaches in donkeys and mules. There is still much information that is not available about donkeys; in many circumstances, the clinician must use available equine information to treat the patient, while monitoring carefully to observe for differences in response to therapy compared to the horse. 相似文献

In the Swiss horse population, the prevalence of conspicuous behaviours (behavioural disorders and stable vices) was recorded with a written questionnaire in a representative survey among 1861 horse yards, and the occurrence of the stereotypic behavioural disorders crib-biting, weaving and boxwalking was analysed with emphasis on their association with horse specific (breed, age, sex) and environmental factors (e.g. housing system, nutrition, management and utilisation). 622 horse yards with a total number of 2536 horses answered to the questionnaire, and conspicuous behaviours were described for 418 horses (16.5%). Thereof, the most common stereotypic behavioural disorders with a potential negative impact on animal welfare, crib-biting, weaving, and/or boxwalking were named for 89 horses (3.5%). Stable vices (e.g. shying, bucking, aggressivity against humans) were noted for 47 horses (1.9%). For 281 horses (11.1%) conspicuous behaviours such as pawing, lip-liking, head shacking, kicking stall were given; these can be categorised as behavioural disorders or as stable vices depending on their intensity and causation. Data analysis data revealed a number of statistically significant associations between genetic factors (breed), housing, management practices, utilisation and the three stereotypies. The strongest influence on the degree of behavioural disorders had the breed as well as the extent of direct social contact with other horses, free movement on pasture, feeding pattern and regular utilisation. 相似文献

Equine welfare charities have identified the education of (primarily novice) horse owners as the principal route to tackling the majority of equine welfare problems in the United Kingdom. To reach and educate owners effectively, we must understand where they seek advice about issues that arise when owning or caring for a horse. Questions regarding information-seeking behavior were included in an Internet survey completed by a convenience sample of 1,326 UK leisure horse owners, recruited online and through electronic and postal mail shots to equestrian clubs and establishments. The questions asked where the owners sought advice regarding 4 different subject areas: horse behavior, health, stable care, and training. Respondents were asked to select their main sources of information from a list of 7—books/magazines, vet/farrier, instructor, Internet/forums, friends/family, tack shops, and other. Although books/magazines were the most frequently used information source across all 4 subject areas overall, there were differences between the 4 subject areas in the most commonly selected sources (χ2 = 992, P < 0.001) and the number of sources consulted (χ2 = 254, P < 0.001). Vets/farriers were the source consulted most frequently for health advice (Z = ?13.32, P < 0.001), instructors for training advice (Z = ?3.93, P < 0.001), and books/magazines for advice regarding both behavior (Z = ?9.49, P < 0.001) and stable care (Z = ?8.26, P < 0.001). Despite the survey mode and that many participants were recruited online, Internet/forums were only the third to the fifth most used of the 7 information sources, depending on the subject area. Logistic regression analyses identified significant associations between owner demographics (age, self-rated skill level, and self-reported rider type) and the likelihood of selecting a particular source for advice regarding a specific subject area. The findings have important implications for those trying to reach the horse-owning population to disseminate research findings and ultimately improve the welfare of their horses. 相似文献

Genetic testing offers precise and accurate data to horse owners concerning their horse’s health and offers potential economic value increases of foal crops via genome-assisted selection. Despite availability of at least 96 commercially available markers, fewer than 20 are commonly used. This project seeks to identify the barriers to the incorporation of genomic tools in diverse equine operations. Based on studies examining public opinion of human medical testing, we expected that lack of genetic education and few industry requirements for testing may contribute to neutral or negative opinions regarding genomic tools for horses. We developed a 20 total question survey to capture demographic information such as facility size, type, and primary breed, as well as horse owner familiarity, use, and outlook regarding equine genetic testing. Question types included multiple choice, Likert-type scale, and open-ended response. Recruitment through county extension agents and breed organizations supplied a broad sampling of the Florida horse industry. Responses were collected from February through May 2019. Data showed that 25% of horse owners had genetically tested their horses (n = 60). Of these consumers, 80% rated the quality of their experience as “excellent” or “good” (n = 15). There was a significant positive association between genetic education and likelihood to genetically test. Most respondents (65%) were interested in receiving information regarding genetic testing. Study participants preferred to find materials on genetic testing through Web-based articles and veterinarians. Results of this study will provide researchers with critical knowledge of their audience’s needs and a roadmap to tailor future educational resources. 相似文献

A cross-sectional study was conducted involving 759 Australian horse owners to determine their biosecurity practices and perceptions one year after the 2007 equine influenza outbreak and to investigate the factors influencing these perceptions and practices. A web link to an online questionnaire was sent to 1224 horse owners as a follow-up to a previous study to obtain information about biosecurity perceptions and practices, impacts of the 2007 EI outbreak, demographic information and information about horse industry involvement. Ordinal logistic regression analyses were conducted to determine factors associated with poor biosecurity practices. Biosecurity compliance (low, medium, high), as determined by horse owners' responses to a 16-item question on the frequency of various biosecurity measures, was used as the outcome variable in ordinal logistic regression analyses. Variables with a univariable p-value ≤0.2 were eligible for inclusion in multivariable models built using a manual stepwise approach. Variables with a p-value <0.05 in multivariable models were retained in the final model. Two potential confounders - age and gender of participants - were included in the final model irrespective of their p-values. Thirty percent of the respondents had low biosecurity compliance and were performing biosecurity practices 'not very often' or 'never'. Younger people, people with two or more children, those who were not involved with horses commercially and those who had no long-term business impacts resulting from the 2007 EI outbreak were more likely to have lower biosecurity compliance. People who were not fearful of a future outbreak of equine influenza in Australia and those who thought their current hygiene and access control practices were not very effective in protecting their horses also had poor biosecurity practices. In this observational study we identified factors associated with a group of horse owners with low levels of biosecurity compliance. As this cross-sectional study only assesses associations, the identified factors should be further investigated in order to be considered in the design of extension activities to increase horse owners' biosecurity compliance. 相似文献

Reasons for performing study: Geriatric horses (aged ≥15 years) represent a substantial proportion of the equine population, yet very few studies have investigated the prevalence of diseases within the UK equine geriatric population. Objectives: To describe the provision of routine preventive health care measures, prevalence of clinical signs of disease and the prevalence of owner reported diseases. Additionally, the effect of increasing age on the provision of preventive health care and the presence or absence of clinical signs and disease was assessed. Methods: A cross‐sectional study was conducted, surveying a randomly selected sample of veterinary registered owners with horses aged ≥15 years, using a self‐administered postal questionnaire. Results: As geriatric horses increased in age, there was a reduction in the provision of preventive health care measures, such as vaccination, farrier care and routine veterinary checks. Only 68.7% of horses had received a routine veterinary visit within the previous 12 months. Owners frequently observed clinical signs in their animals, with 77% reporting at least one clinical sign of disease. Increasing age was associated with increased reporting of many clinical signs of disease. Over half (58%) of horses had at least one episode of disease within the previous 12 months, yet only 31% of owners reported that their animal currently suffered from a known disease or disorder. Conclusions and potential relevance: Although owners frequently observed clinical signs in their aged horse, there may be incorrect or under recognition of many diseases and health problems. Reduced frequency of routine preventive health care measures, along with suboptimal owner recognition of health and welfare problems may lead to compromised welfare in the geriatric population. 相似文献

The 2007 epidemic of equine influenza in Australia provided an opportunity to investigate the effectiveness of on-farm biosecurity measures in preventing the spread of a novel pathogen in a largely naive population. We conducted a case-control study of 200 horse premises from highly affected regions of the state of New South Wales (NSW), to investigate risk factors for the spread of equine influenza onto horse premises, specifically, non-compliance with biosecurity measures recommended to horse owners by the relevant animal health authority, the NSW Department of Primary Industries. The study was restricted to cases occurring during the first seven weeks of the epidemic, a period prior to vaccination and the relaxation of some movement restrictions. Case and control premises were selected from a laboratory testing dataset and interviews were conducted with horse owners and managers on premises between July and November 2009. The proximity of premises to the nearest infected premises was the factor most strongly associated with case status. Case premises were more likely than control premises to be within 5 km and beyond 10 km of an infected premises. Having a footbath in place on the premises before any horses were infected was associated with a nearly four-fold reduction in odds of infection (odds ratio=0.27; 95% confidence interval: 0.09, 0.83). This protective association may have reflected overall premises biosecurity standards related to the fomite transmission of equine influenza. Compliance with certain on-farm biosecurity practices seemingly prevented horses on premises in high risk areas being infected with equine influenza during the 2007 outbreak in Australia. In future outbreaks, in addition to broader disease control measures, on-farm biosecurity practices should be adopted by horse owners and managers to prevent equine influenza spread. 相似文献

Economic stress and geographic isolation are barriers to proper veterinary care for horses on Native American reservations. The 2011 South Dakota (SD) Equitarian Survey was distributed to 135 equine veterinarians in SD to detect perceptions of effectiveness and best methodologies for improving reservation equine welfare. There was a positive correlation (P < .005) between the perceived importance and effectiveness of increased veterinary access and the importance of free care and owner knowledge in changing the health and welfare of SD’s reservation equine population. Thirty-nine percent of respondents claimed to have an interest in providing help for reservation equines; those with no veterinary experience on reservations tended not to have interest (P = .05). Previous experience practicing on a reservation impacted how crucial they believed horse owner knowledge or awareness was in changing the health and welfare of reservation equines (P < .04). The most commonly noted health threat and strength were poor nutrition and the absence of internal disease, respectively. In a subsequent analysis, 299 horses on the Cheyenne River Sioux Reservation were observed for welfare indicators and divided into groups by use: saddle, production, bucking stock, and performance. Average body condition score was 5 of 9 and did not differ between the four groups. Coat (P < .001) and hoof (P < .007) conditions varied between groups, with optimal conditions in the performance and saddle horse groups, respectively. Variable hoof, coat, and vaccination practices among the groups of reservation equines present an opportunity for health care education and welfare improvement. 相似文献

Substrate depletion and end product accumulation are two important factors in exercise fatigue. Fatigue during long-term exercise results from a depletion of muscle and liver glycogen and coincides with an inability to maintain blood glucose levels. During high intensity exercise, the rapid catabolism of carbohydrate and the resultant production of lactate and hydrogen ions cause a reduction in muscle pH that inhibits maximum force generation. Dietary manipulations that can influence carbohydrate status or lactate accumulation may be beneficial to performance. In human athletes, carbohydrate loading and carbohydrate supplementation can enhance endurance time during long-term exercise. These practices have not been explored extensively in the equine athlete, although glycogen loading does not enhance the performance of horses during short-term intense work. Short-term work can be detrimentally affected if glycogen levels are inadequate. The most marked effect of exercise on nutrient requirements is in the energy requirement. Horses in heavy training may require more energy than they can consume on a conventional diet. Fat has been added to horse diets to increase energy density, usually at levels between 6% and 12% of the total diet. Although protein requirements may be slightly increased in the working horse, supplementing protein as a means of adding calories is not an efficient practice. In addition, although studies with horses are not available, human studies indicate that there are no benefits to vitamin supplementation above required levels. At this point, more is unknown than is known about feeding performance horses. Most information on fuel utilization is extrapolated from studies with rats and humans. Areas that have received little attention but are critical to optimizing feeding practices are the timing of pre-event feeding and the determination of ideal body composition in equine athletes of different types. 相似文献

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. 相似文献

Intense selection for speed, endurance or pulling power in the domestic horse (Equus caballus) has resulted in a number of adaptive changes in the phenotype required for elite athletic performance. To date, studies in humans have revealed a large number of genes involved in elite athletic performance, but studies in horses are rare. The horse genome assembly and bioinformation tools for genome analyses have been used to compare human performance genes with their equine orthologues, both to retrieve pathways for these genes and to investigate their chromosomal distribution. In this review, 28 candidate genes for equine performance are presented that have polymorphisms associated with human elite athletic performance and may have impact on athletic performance in horses. A significant accumulation of candidate genes was found on horse chromosomes 4 and 12. Genes involved in pathways for focal adhesion, regulation of actin cytoskeleton, neuroactive ligand-receptor interaction, and calcium signalling were over-represented. Genome-wide association studies for athletic performance in horses may benefit from the strong conserved synteny of the chromosomal arrangement of genes in humans and horses. 相似文献
