The relationship between horse owners and horses encompasses various aspects of equine management, care, and interaction. This topic explores the dynamics between humans and horses, focusing on areas such as husbandry practices, welfare considerations, and the psychological and physical effects of human interaction on horses. It includes studies on training methods, behavioral assessments, and the impact of owner expertise on horse health and performance. Additionally, the topic examines the influence of human-animal bonds on horse behavior and well-being. This page compiles peer-reviewed research studies and scholarly articles that investigate these interactions and their implications for equine management and welfare.
Chandler KJ, Billson FM, Mellor DJ.Ophthalmic lesions were detected in 67 of 83 horses and ponies aged 15 years or more. Degeneration of the vitreous, followed by senile retinopathy, were the most common lesions and both of them became more common with advancing age, although few of the owners reported disturbances of vision in their animals.
Robinson VL, Smith BB, Arnone A.In 1947, Perutz and co-workers reported that crystalline horse methemoglobin undergoes a large lattice transition as the pH is decreased from 7.1 to 5.4. We have determined the pH 7.1 and 5.4 crystal structures of horse methemoglobin at 1.6 and 2.1 A resolution, respectively, and find that this lattice transition involves a 23 A translation of adjacent hemoglobin tetramers as well as changes in alpha heme ligation and the tertiary structure of the alpha subunits. Specifically, when the pH is lowered from 7.1 to 5.4, the Fe(3+) alpha heme groups (but not the beta heme groups) are converted from...
Dixon PM, McGorum BC, Railton DI, Hawe C, Tremaine WH, Dacre K, McCann J.There is continuing debate on the clinical benefit of laryngoplasty (LP) in the treatment of equine laryngeal paralysis. In particular, there is little information available on the clinical value of this surgery in older horses, in non-Thoroughbreds or in sports or pleasure horses; nor on the relationship between the degree of LP abduction achieved and the clinical value of LP. Objective: To evaluate the owner's assessment of the value of LP (and combined ventriculocordectomy) in an older, mixed breed and mixed workload population of horses and to also assess the relationship between the degre...
Brosnahan MM, Paradis MR.To describe the demographic and clinical characteristics, management practices, and owner perception of a population of geriatric horses, and to compare these data with findings in a group of younger horses. Methods: Original study. Methods: 218 horses. Methods: Data were collected via a survey tool from owners of 165 horses that were > or = 20 years of age and 53 horses that were < 20 years of age. Results: Compared with young horses, the geriatric group included a significantly greater number of ponies; geriatric horses were also more likely to have a history of colic, dental disease, ...
Roy MF, Lavoie JP.Respiratory disorders are among the most common problems leading horse owners to seek veterinary attention. Accurate diagnosis of these conditions allows for proper treatment to be instituted, much to the benefit of the patient and satisfaction of the client. As an introduction to this issue on equine respiratory disorders, we review some of the tools that are available to equine veterinarians for the diagnosis of respiratory disorders. Physical and endoscopic examination, radiology, diagnostic ultrasound, techniques for sampling the respiratory tract, hematology, blood gas analysis, respirato...
Matthee S, Dreyer FH, Hoffmann WA, van Niekerk FE.Fifty-one per cent of 110 questionnaires, designed for obtaining information on helminth control practices and management on Thoroughbred stud farms in South Africa, were completed by farmers during 2000. The number of horses per farm included in the questionnaire survey ranged from 15 to 410. Foals, yearlings and adult horses were treated with anthelmintics at a mean of 7.3 +/- 3.0, 6.6 +/- 2.7 and 5.3 +/- 2.3 times per year, respectively. An average of 3.4 different drugs were used annually, with ivermectin being used bymost farmers during 1997-2000. On 43% of farms the weights of horses wer...
Wagner IP, Rees CA, Dunstan RW, Credille KM, Hood DM.To determine whether systemic immunologic hyperreactivity exists in horses with chronic laminitis, compared with responses for nonlaminitic horses. Methods: 7 nonlaminitic horses and 7 CL horses. Methods: In experiment 1, intradermal testing (IDT) was performed on 7 nonlaminitic and 7 CL horses to evaluate the response to a combination of 70 allergens at 15 and 30 minutes and 4 and 24 hours after injection. Three nonlaminitic and 3 CL horses used in experiment 1 were used in experiment 2 to determine whether histologic differences existed between the 2 groups. The H&E-stained tissue sectio...
Bachmann I, Audigé L, Staﾬher M.Studies on the prevalence of behavioural disorders in horses and on associated risk factors have revealed inconsistent results. There are many studies on the neuropharmacological, surgical or mechanical therapy of stereotypies, but little is known about their causation. Objective: To explore risk factors associated with the occurrence of behavioural disorders in horses. Methods: A sample of horse owners, selected randomly and representative for Switzerland, was contacted in a postal survey. Answers were provided for 622 stables (response rate 35.2%). Individual data of 2,341 horses were examin...
Mills DS, Taylor K.Thirty-six owners of seasonally headshaking horses took part in a trial to compare the effectiveness of three types of nose net, a traditional cylindrical net (full net) and two forms of larger mesh nets which cover only the nostrils and dorsorostral muzzle (half nets). Baseline data relating to the overall severity of the problem and 18 specific behaviours describing the nature of the problem were recorded on a check sheet by the owners. A within-subjects repeated measures design experiment, with each net used for a week before reassessment, was then used to assess the effect of the nets on t...
Paradis MR.Owners of older horses have generally owned them for a long time. They have developed a bond that is similar to that seen with companion animals. Their desire to have their animal(s) age gracefully with comfort and mobility has stirred research in the field of equine geriatric medicine. Equine geriatric medicine is to the first decade of the twenty-first century as neonatal medicine was to the 1980s. Hopefully, the demographics discussed in this article highlight area where research can be most helpful.
Graham BP.Dental care in any horse need not be looked at as the difficult challenge it used to be before the days of sedation and tungsten carbide and diamond cutting wheels. Horses are living longer and more comfortable lives thanks, in part, to the advancements of dental care and special dietary rations. With the evolution of the horse's place in family circles today, people want the best care possible for their animals. Dentistry has become an important part of that care.
O'Meara B, Mulcahy G.We report the results of a survey to assess the attitudes of horse owners and managers of equine businesses in Ireland to the control of helminth parasites, and the extent to which veterinary practitioners are involved in providing advice on parasite control of horses. Replies to our questionnaire indicated that there is a high level of awareness on the need for helminth control, typically leading to several doses of anthelmintic being administered to each animal every year. While a majority of respondents (61%) were concerned about the issue of anthelmintic resistance, only a few were of the ...
Larsen MM, Lendal S, Chriél M, Olsen SN, Bjørn H.A questionnaire survey regarding endoparasite control practices in Danish horse herds was carried out in 1995. The participating veterinarians and herd owners were sampled using convenience and purposive sampling. In the analysis of risk factors for development of a high endoparasitic burden (> 200 eggs per gram faeces) 903 horses were sampled and the analysis of the efficiency of a single anthelmintic treatment was based on 605 horses. The following factors had a significant effect on the endoparasitic burden: herd type, age of the horses, use of pasture rotation, anthelmintic treatment of ho...
Fisher J.The life and work is told of John Pottie (1832-1908), a Scotsman who graduated from Edinburgh Veterinary College in 1858. A year later, he contracted to provide veterinary care to a consignment of horses bound for Australia. Once there, he founded a firm that has survived to the present day, still marketing products that originated in his own veterinary remedies. John Pottie brought with him a European tradition of livestock care and treatment that was epitomised in Clater's title and book, Every man his own farrier. His career is of interest for several reasons. Firstly it is because he used ...
Bates A.1. Horses, just by their large, gentle presence, put people therapeutically in touch with the vitality of being alive. 2. People who ordinarily shun physical and emotional closeness often can accept closeness from a horse and through therapy can transfer these skills to their daily lives. 3. The behavior of a sensitive horse display the rider's emotions to the therapist and provides a vehicle the therapist can use to teach the patient coping skills. 4. Therapists with an interest in horses can learn more about how to become involved in an equine-facilitated psychotherapy practice through the N...
McCauley CT, Hawkins JF, Adams SB, Fessler JF.To determine outcome of horses in which cutaneous masses were removed with a carbon dioxide laser. Methods: Retrospective study. Methods: 32 horses. Methods: Medical records of horses with 1 or more cutaneous masses treated with a carbon dioxide laser were examined. Follow-up information was obtained through telephone interviews with owners and referring veterinarians. Results: Cutaneous masses were classified as sarcoids (15 horses), neoplastic masses other than sarcoids (squamous cell carcinoma [91; fibroma [1]; and melanoma [1]), and nonneoplastic masses (6). Minimum follow-up time was 6 mo...
Magnusson LE, Ekman S.Osteoarthrosis (OA) of the antebrachiocarpal joint from 7 riding horses is described. The horses were old mares and developed severe OA, with ankylosis in some of the joints. The lesions were bilateral, and the owners noticed the lameness in a late event. The cause of severe OA in these mares is not clear. The fact that OA was bilateral indicates that a single traumatic injury is unlikely as an etiologic factor. Considering the severe joint lesions it took long time before the horse-owners noticed the lameness. It is discussed if the threshold of pain is higher in the antebrachiocarpal joint c...
Mills DS, Cook S, Taylor K, Jones B.A national survey of headshaking in 254 horses was undertaken to describe the clinical signs of the condition as observed by horse owners. Principal component analysis was used to determine the underlying structure of 11 signs and the criteria by which the affected horses could be most effectively differentiated; the analysis suggested five components with a variance greater than one which together explained over 60 per cent of the total variance. Other analyses of the data indicated that headshaking could develop at any age and that twice as many males were affected as females; 64 per cent of...
Barr AC, Reagor JC.Horses poisoned by a plant may show a myriad of clinical signs. Awareness of the poisonous plants growing in a given area and those that are likely to appear in hay and their associated clinical signs can be instrumental in making diagnoses. More importantly, the information can be shared with clients to help prevent plant poisonings in horses.
Poppenga RH.The use of dietary supplements (herbs, vitamins, minerals, amino acids, enzymes, and other compounds) is common in horses. They are heavily marketed in retail stores, magazines, and on the Internet. There is the perception that since these compounds are "natural" they are devoid of toxicity, and, therefore, they are safe to use. Some of the active compounds in supplements, however, have inherent toxicity, and using them may cause adverse effects. Even relatively non-toxic ingredients may be toxic if used over-zealously or for a long period of time. By and large, these compounds have not been t...
Puschner B, Galey FD.Poisoning in the horse can present a highly complex case. The practitioner, owner, toxicologist, and pathologist play important roles, and all contribute information that may be important to the case. Once all the information is available, all the evidence is collected (historical, clinical, pathologic, and analytic), and proper sampling of specimens has occurred, a complete summary of the findings can be provided to the client. Based on identification of a potential toxic source and, ultimately, the diagnosis, specific treatment of affected animals and prevention of additional cases can be in...
Mellor DJ, Love S, Walker R, Gettinby G, Reid SW.Details of the management, feeding, level of activity and routine health care of horses in Scotland and the five northernmost counties in England were recorded through a stratified random sample of horse owners who had responded to a previous survey. Sixty-eight per cent of the horses were kept where their owners resided, and 32 per cent were kept away from the owner's home. More than 99 per cent were turned out to grazing for at least part of the year and 81 per cent were stabled for at least part of the time, most commonly bedded on straw (50 per cent) or shavings (34 per cent). Hay was fed ...
Bohanon TC, Beard WL, Robertson JT.Case records of 27 draft horses with laryngeal hemiplegia were reviewed. Twenty-one horses were treated by ventriculectomy with or without prosthetic laryngoplasty, and 17 owners were contacted to determine the results. Fifteen horses improved after surgery and were able to perform to the owners' expectations. Performance improved significantly and hospitalization was shorter after ventriculectomy alone. Results of this study indicate that the clinical signs of exercise intolerance and excessive inspiratory noise associated with left laryngeal hemiplegia in draft horses can be treated successf...
Grubbs ST, Amodie D, Rulli D, Wulster-Radcliffe M, Reinemeyer C, Yazwinski T, Tucker C, Hutchens D, Smith L, Patterson D.The safety and efficacy of 2% moxidectin/12.5% praziquantel oral gel administered at a rate of 0.4 mg moxidectin and 2.5 mg praziquantel/kg was studied in client-owned horses under field use conditions. Four hundred horses (300 treated with moxidectin/praziquantel oral gel and 100 treated with vehicle) were enrolled, feces were collected, and eggs were counted. Investigators as well as horse owners were masked to treatment assignment. No adverse reactions to treatment were observed in any horses. Moxidectin/praziquantel gel reduced Anoplocephala spp by more than 99% and provided a significant ...
Gehlen H, Loschelder J, Walther M.Euthanasia represents a procedure with high responsibility for veterinarians in equine practice. The procedure should avoid pain and suffering for the horse and be carried out with the least possible stress for the patient and its owner. The presented study investigated the emotional impact of a horse's euthanasia procedure on the owner in order to enable development of future recommendations in improving the management of this procedure in horses. Methods: Questionnaires concerning euthanasia of a horse for horse owners and veterinarians, respectively were developed and sent by mail or publis...
Bischoff K, Moiseff J.Feed as a cause of poisoning in horses can occur on small or large scales. It is challenging to work up cases of suspected feed contamination, but there are resources available to veterinarians and owners. Feed contamination can be chemical or biological. This article focuses on and provides examples of chemical feed contamination including misformulation, adulteration, and natural contaminants. Additionally, recommendations for feed sampling and diagnostic submission, including legal documentation, are included.
Lacroix G, Lacroix C.This article discusses equine associate employment agreements from the employer's perspective. It should also be of interest to prospective equine associates. The substantive issues and questions are the same, and neither employers nor employees are likely to get far unless they "walk a mile in the other's moccasins".
Peitzmeier MD, Koontz ZD, Lynch TM, Hughes FE, Slone DE.This retrospective study provides long-term results of medial patellar ligament (MPL) desmoplasty in horses with intermittent upward fixation of the patella (UFP) that were treated at a single referral hospital over a 7-year period. Follow-up interviews were conducted with owners, trainers, or referring veterinarians using a standardized questionnaire. Overall, 71% of horses returned to their intended use with only 18% at a higher level. Recurrence of UFP was noted in 33% of cases. Satisfaction with the procedure was generally low, with only 50% of owners being completely satisfied. Further in...
Weaver MP, Wilant L.A postal survey of the owners of Clydesdale horses in the UK and USA was conducted to obtain information on tarsocrural effusion ('bog spavin') as an indicator of osteochondrosis from 935 horses. Additional information requested included details of how this condition was investigated and treated. The reported tarsocrural effusion incidence was 10 per cent. The majority of respondents believed the condition to be of concern to Clydesdale owners, but only a minority were aware of the implications of tarsocrural effusion, suggesting that owner education would be of benefit.
Evans DR.In reporting the results of the medical examination for purchase, the veterinarian should not make an evaluation as to the animal's suitability for the purpose intended but should rather reveal all of the abnormal and undesirable findings and give his or her opinion as to the effect these findings will have on the performance of the horse for the purpose intended. A written report should be provided, and any factors that have had an influence on the opinion rendered should be a part of the report. A record of all procedures performed, the results of these procedures, the names and addresses of...
Gill Harris reports from this year's National Equine Forum, where one of the main themes was the horse industry and government. The forum, held in London on March 5, was attended by more than 200 people with a connection to the equestrian industry. Lord de Mauley, parliamentary undersecretary of state for natural environment and science at Defra, set the course of the proceedings.
Löfqvist L, Pinzke S.The horse industry in Sweden has rapidly expanded in recent years. This increasing number of horses implies a greater need for more farriers. Shoeing a horse is hard physical work, and includes awkward work postures and repetitive movements. It is well known that hard physical work increases the risk of injuries and musculoskeletal problems. The risk is especially high for musculoskeletal disorders when certain movements are constantly repeated. Heavy or repeated unilateral loads lead to considerable stress on the muscles, which can lead to rupture and fatigue that can cause long term problems...
Haussler KK.Integrative medicine is based on a model of being proactive and promoting health and wellness, rather than being reactive and solely focusing on episodic disease processes. Integrative medicine incorporates a holistic approach to clinical practice that encourages owner involvement with a focus on individualized care, maintained wellness, optimized performance, and disease prevention. Health promotion and preventative care require a different set of clinical skills and perspectives than is typically provided by a traditional veterinary education. Productive interprofessional collaborations are ...
Werner SH.Quality medical records are the cornerstone of successful equine veterinary practice. The scope and integrity of the information contained in a practice's medical records influence the quality of patient care and client service and affect liability risk, practice productivity, and overall practice value.
Harman J.Examining the fit of the saddle is perhaps the most important aspect of examining a horse with a suspected back problem. If the back problem is corrected and a poorly fitting saddle is placed on the back, the problems will return. An ill-fitting saddle contributes to direct and compensatory lower leg lameness making it even more imperative to correct the fit. A correctly fitting saddle enhances both the horse and rider's ability to perform with accuracy, lightness, and freedom of movement.
Lesser FR, Cowles RR.In this article, the author discusses the design of an equine ambulatory practice. He suggests a more systematic approach to the design of an ambulatory practice that should answer the needs of group and solo practices. Today's practitioners must actively manage their practices so that their resources can be leveraged in such a fashion that a return can be realized on their capital investment and the hours spent in practice.
Marsella R, Akucewich L.The purpose of this prospective, double-blinded, placebo-controlled clinical trial was to investigate the efficacy and tolerability of a novel gel containing 0.4% stannous fluoride (MedEquine) for the treatment of cutaneous bacterial infections in horses. Twenty privately owned horses diagnosed with bacterial skin infections based on physical findings and cytology results were enrolled and randomly assigned to either a placebo or an active ingredient treatment group. The product was applied on affected areas daily for 4 weeks. Cytology and clinical evaluations were done by the same investigato...
Bookbinder L, Prisk A.Gastrointestinal colic is the most common primary care equine emergency and affects nearly one of four horses per year. Colic is a significant welfare concern for equine patients and a financial and emotional burden for owners. The primary care practitioner is instrumental in identifying critical cases quickly and making appropriate management recommendations to improve patient outcomes.
Caudle AB, Pugh DG.The object of restraint is to limit, restrict, and keep under control the animal's movement while performing different procedures. The author discusses the importance of evaluating the horse and its owner prior to employing any type of restraint, various concepts of restraint, and examples of situations in which restraint may be required.
Tivey ML.Mary-Ellen Lloyd Tivey of the Royal Veterinary College, suggests that greater collaboration and encouraging engagement from horse owners and vets is key to strengthening scanning surveillance in equine populations.
Wallace J.With concerns growing globally about anthelmintic resistance in equine endoparasites, James Wallace's practice undertook some research among its horse-owning clients and introduced a fixed-fee parasite management programme to help ensure the most effective use of these valuable medicines.
Farchati H, Merlin A, Saussac M, Dornier X, Dhollande M, Garon D, Tapprest J, Sala C.Identifying and tracking equines are key activities in equine health prevention. France is one of the few European countries with an operational centralized database that records information on equines, owners, and keepers but not on the location and keeping conditions of equines. The objective of our study was to collect information on keeping habits of equines and the relative location of a wide range of equines, owners, and keepers and discuss their implication for surveillance and control of outbreak improvement. A national email survey was conducted among the 1.9% of people registered as ...
Rollin B.This research paper discusses the responsibility of humans towards animals they own, focusing specifically on the concept of the “unwanted horse”. The author argues that once a human acquires an […]
Romero MH, Meneses F, Sanchez JA.The welfare of working equids in developing countries is sometimes threatened due to the limited resources and/or knowledge of their owners. The objective of this study is to evaluate the welfare of creole horses and mules using a validated protocol that assesses animal-based indicators. A total of 160 horses and 40 mules from three municipalities in the Colombian coffee-growing region were evaluated by means of direct observation of health and behavioral parameters. A descriptive analysis of the variables expressed in proportions was performed. Interactions between the different measurements ...
Sill S, Zhao L, Houpt K.Salt (NaCl) is an essential nutrient for horses because their diet is low in sodium and they lose salt in sweat. Given the many types of salt block available, 342 horse owners were surveyed to see what type they offered their horses. The owners most often offered plain(30%) mineralized (29%) or Himalayan salt blocks. Next, adult mares were given two choice preference tests between plain (white) and mineralized (red) salt blocks, between mineralized and selenium (green) blocks, between plain and selenium, between Himalayan (pink) and plain and between Himalayan and selenium salt blocks. The hor...
Ramadan MM, Dailey D.This is the first account of fatal toxicity in horses resulting from grazing on the pasture plant creeping indigo, , on the island of Oahu, in the Hawaiian Islands. A survey in the town of Waialua on the north shore of Oahu island indicated that creeping indigo is common and abundant on grazing lands during the rainy season and requires intensive chemical and physical control measures. Four pastures were surveyed where ranchers reported mortality of more than 17 horses since 2020. We document these incidents to alert state animal and livestock support officials, groups monitoring invasive spec...
Dickey JP, Carmalt JL, Reiswig JD.The determination of a horse's age by its dentition is a technique that has been employed by horse owners and professionals since at least 600 BC. While aging teeth based on incisor wear patterns is common, wear patterns in the cheek teeth may also be useful. As horses continue to live longer, we routinely examine horses into their 20's and 30's, and it is becoming more common to observe aging changes in the cheek teeth. To our knowledge, this study is the first to use easily obtained clinical observation of the expiration of cheek teeth infundibula to age horses of advanced ages (16 to 35 yea...
