Horse management encompasses the practices and techniques used to care for and maintain horses in various settings, including stables, pastures, and performance environments. This area of study covers a range of activities such as feeding, grooming, housing, exercise, and health monitoring to ensure the well-being and optimal performance of horses. Effective horse management requires an understanding of equine behavior, nutrition, and physiology, as well as the ability to implement routine care practices and respond to health issues. This page gathers peer-reviewed research studies and scholarly articles that explore the methods, strategies, and outcomes associated with different horse management practices.
Vacchina V, Ionescu C, Oguey S, Lobinski R.A method was developed for the quantification of Zn-, Cu- and Mn-glycinates in supplemented feed samples. The coupling of capillary electrophoresis (CE) with ICP MS detection after purification of the extract by ultrafiltration was shown to be efficient for the quantitative recovery of glycinates. The method developed was then applied to evaluate the bioaccessibility of glycinates using a sequential enzymolysis approach. The data obtained indicated a strong bioaccessibility of each element (79-94%). A new complex was also found to be formed during the digestion process. Bioavailability was the...
Zeyner A, Romanowski K, Vernunft A, Harris P, Kienzle E.Based on a series of exercise tests which included the estimation of sweat losses, this article proposes a novel sweat scoring system for exercising horses. This provides a practical estimate of individual animal exercise-induced sweat losses, based on visible appearance of sweat on the coat after work, which takes into account the effect of various influencing factors. In terms of accuracy and flexibility, the score seems to provide advantages over estimates based on current general recommendations from reference books. Additional studies are needed to validate this scoring system and its use...
Schemann K, Lewis FI, Firestone SM, Ward MP, Toribio JA, Taylor MR, Dhand NK.On-farm biosecurity practices have been promoted in many animal industries to protect animal populations from infections. Current approaches based on regression modelling techniques for assessing biosecurity perceptions and practices are limited for analysis of the interrelationships between multivariate data. A suitable approach, which does not require background knowledge of relationships, is provided by Bayesian network modelling. Here we apply such an approach to explore the complex interrelationships between the variables representing horse managers' perceptions of effectiveness of on-far...
Douthit TL, Bormann JM, Kouba JM.The objective of this study was to retrospectively analyze demographic variables and academic preparation of students to determine how these factors relate to student performance in ASI 521 Horse Science, an upper-level course offered in the Department of Animal Sciences and Industry (ASI) at Kansas State University (KSU). Data were collected for 264 students enrolled in the course from 2008 to 2010. Students who took the course in 2008 received greater final percentages than those who took the course in subsequent years (P = 0.0016). Females tended to receive greater percentages than males (P...
Yilmaz O, Wilson RT.Mules are known to have been used as carriage and riding animals in Mesopotamia and Anatolia as early as the beginning of the second millennium BC but may have been first bred in Anatolia in the Third Century BC. They have thus contributed to Turkey's cultural, social and economic heritage for more than 4,000 years and were an ancient component of its guild of domestic animals and overall biodiversity. Once bred country-wide most mules are now introduced "illegally" to the southeast and east from Iraq and Iran. Mules are now bred only in one small area in north-central Turkey close to the Blac...
Ivester KM, Smith K, Moore GE, Zimmerman NJ, Couëtilt LL.Exposure of horses to airborne particulates during stable confinement has been linked with airway inflammation in these animals. Understanding that link requires accurate measures of exposures and greater understanding of the sources of variability in these exposures. Objective: Area and breathing zone particulate concentrations were measured over time in order to determine the relative variability introduced by daily, monthly or between horse variations. Additionally, the relationship between area and breathing zone respirable particulate concentrations was examined. Methods: The study was co...
Suthers JM, Pinchbeck GL, Proudman CJ, Archer DC.Risk factors for large colon volvulus (LCV) in the horse have not been previously reported. Knowledge of these risk factors may allow the introduction of measures that could be taken to minimise the incidence of LCV. Objective: To investigate risk factors for LCV in the horse. Methods: A prospective, multicentre, unmatched case-control study was conducted over a 24 month period in the UK. Data on 69 cases and 204 control horses, from 4 veterinary hospitals, were obtained via telephone questionnaires. Multivariable logistic regression was used to identify associations between horse and manageme...
Slater J.The London 2012 Olympic and Paralympic Equestrian Games were the highest profile event in the 2012 equestrian calendar and were the culmination of four years of detailed and meticulous biosecurity planning to ensure that all horses arrived, competed and returned home safely and in good health. Josh Slater, Anthony Greenleaves and Andy Paterson describe how this was achieved.
Briefer Freymond S, Briefer EF, Von Niederhäusern R, Bachmann I.Horses are often kept in individual stables, rather than in outdoor groups, despite such housing system fulfilling many of their welfare needs, such as the access to social partners. Keeping domestic stallions in outdoor groups would mimic bachelor bands that are found in the wild. Unfortunately, the high level of aggression that unfamiliar stallions display when they first encounter each other discourages owners from keeping them in groups. However, this level of aggression is likely to be particularly important only during group integration, when the dominance hierarchy is being established,...
Relf VE, Morgan ER, Hodgkinson JE, Matthews JB.Few studies have described the combined effect of age, gender, management and control programmes on helminth prevalence and egg shedding in grazing equines. Here, fecal samples collected from 1221 Thoroughbred horses, residing at 22 studs in the UK, were analysed. The distribution of strongyle eggs amongst individuals in relation to age, gender and management practices was investigated. Fecal worm egg counts (FWECs), described as the number of eggs per gramme (epg) of feces, were determined using a modification of the salt flotation method. The FWEC prevalence (mean%) of strongyles, Parascaris...
Leung GN, Kwok WH, Wan TS, Lam KK, Schiff PJ.Formestane (4-hydroxyandrost-4-ene-3,17-dione) is an irreversible steroidal aromatase inhibitor with reported abuse in human sports. In 2011, our laboratory identified the presence of formestane in a horse urine sample from an overseas jurisdiction. This was the first reported case of formestane in a racehorse. The metabolism of formestane in humans has been reported previously; however, little is known about its metabolic fate in horses. This paper describes the in vitro and in vivo metabolic studies of formestane in horses, with the objective of identifying the target metabolite with the lon...
Guyton K, Houchen-Wise E, Peck E, Mayberry J.Horse-related injury can be severe and disabling. We investigated the causes, severity, and costs of equestrian injury with the goal of injury prevention. A retrospective review of horse-related injuries from 2001 to 2008 identified 231 patients with a mean age of 38 years and a mean Injury Severity Score of 11 (range, 1 to 45). Mean length of stay was 5.5 days. Fifty-nine patients (25%) required 84 surgeries. Helmet use was 20 per cent and of the 172 patients not wearing a helmet while mounted, 38 per cent received potentially preventable head injuries. There were three deaths of which two we...
Kwok WH, Ho EN, Lau MY, Leung GN, Wong AS, Wan TS.In recent years, there has been an ongoing focus for both human and equine doping control laboratories on developing detection methods to control the misuse of peptide therapeutics. Immunoaffinity purification is a common extraction method to isolate peptides from biological matrices and obtain sufficient detectability in subsequent instrumental analysis. However, monoclonal or polyclonal antibodies for immunoaffinity purification may not be commercially available, and even if available, such antibodies are usually very costly. In our study, a simple mixed-mode anion exchange solid-phase extra...
Hessler C, Eckert V, Meiners J, Jürgens C, Reicke B, Matthes G, Ekkernkamp A, Püschel K.Horse riding is associated with a high rate of injuries. The possibilities of prevention are limited because of deficient knowledge about the causes and mechanisms of equine-related accidents. In the present study 198 equine-related accidents were analyzed and based on these data risk groups were identified and guidelines to improve safety in horse riding were formulated. Methods: In this 2-center study the accidents of 169 riders over a period of 12 months were analyzed. Data on equine-related patterns of injury and the resulting treatment were collated from the clinical records. Additionally...
Cook WR, Mills DS.The study tested the null hypothesis that if a horse is ridden in a snaffle bridle and then a crossunder bitless bridle, there will be no change in its behaviour. It was predicted that there would be change and that behaviour would improve when bitless. Four horses, none of which had ever been ridden in a crossunder bitless bridle, were ridden through two 4 min, exercise tests, first bitted then bitless. An independent judge marked the 27 phases of each test on a 10 point scale and comments and scores were recorded on a video soundtrack. The results refuted the null hypothesis and upheld the p...
McGreevy PD, Nicol CJ.Crib-biting is a common oral stereotype. Because of perceived deleterious effects on the health and appearance of subjects the prevention of crib-biting is regularly attempted. The resourcefulness of horses in satisfying their motivation to perform this behaviour often frustrates owners' efforts at prevention. This paper reviews the efficacy and observable consequences of attempting to prevent crib-biting by a variety of methods. These include attempts to prevent the grasping of objects, to interfere with air-engulfing and to introduce punishment for grasping and neck-flexion. Other approaches...
Li J, López Adán E, de la Rubia Riaza A.China competed in equestrian sports for the first time at the 2008 Beijing Olympics. China's modern equine business has developed significantly over the past decade, and the lessons from the expansion between 2015 and 2020 are important considerations as China implements further legislation to aid in the development of its modern equestrian sports. Equestrian sports can propel the Chinese horse industry forward, and the horse industry is a unique business in that it integrates one, two, and three industries, with much growth potential. This paper assesses the development of equestrianism in Ch...
Rohlf CM, Garcia TC, Fyhrie DP, le Jeune SS, Peterson ML, Stover SM.Shear forces at the surface-hoof interface affect hoof slide, surface grip, forces transferred to the limb, and injury risk. However, the variation in shear forces among surfaces with different compositions have not been quantified. Shear ground reaction forces were measured on five dirt and seven synthetic arena surfaces. Cohesion/adhesion and angle of internal friction/coefficient of friction were calculated. Surface composition, surface temperature, cushion depth, and moisture content were also measured. The effects of surface material (dirt/synthetic) on shear properties were assessed usin...
Pratt-Phillips S, Munjizun A, Janicki K.Obesity is a critical problem in the equine industry, with ponies being at particularly high risk of developing obesity-related conditions such as metabolic syndrome and laminitis. The purpose of this study was to estimate the level of adiposity in an elite level of competitive show ponies, and to determine if adiposity was related to performance based on their model score (judged on conformation and appearance). Two researchers visually evaluated the body condition score (BCS) and cresty neck score (CNS) of 377 ponies at a national hunter competition. Thirty five percent of the ponies in the ...
Yamada M, Aramaki S, Kurosawa M, Kijima-Suda I, Saito K, Nakazawa H.The use of anabolic steroids in racehorses is strictly regulated. We have developed a method for the simultaneous analysis of 11 anabolic steroids: fluoxymesterone, 17alpha-methyltestosterone, mestanolone, methandienone, methandriol, oxymetholone, boldenone, furazabol, methenolone, nandrolone, and stanozolol, for possible application to a doping test in racehorses. We selected 15 kinds of target substances for a doping test from the main metabolites of these anabolic steroids, and established a method for simultaneous analysis. Urine was hydrolyzed and subjected to solid-phase extraction. Then...
Karasu GK, Rogers CW, Gee EK.Sustainability is the balancing act of optimizing the use of current resources without compromising the current or future environment. Within the agriculture sector the primary focus of sustainability has been to reduce environmental pollution, specifically greenhouse gasses (GHG) emissions, nitrogen emissions, and leaching. For the equine industry the first step towards sustainability is the documentation and critique of current feeding and management practices to permit modifications to enable the industry meet social and legislative obligations. As a monogastric hindgut fermenter on a per k...
Arango-Sabogal JC, Mouncey R, de Mestre AM, Verheyen K.Thoroughbred breeders aim to have foals born early in the season, but scientific evidence on the advantages for race performance is scarce and contradictory. Unassigned: The association between date of birth and purchase price as foal/yearling, with race performance by the end of the second and third years of life of Thoroughbreds racing in flat races in the United Kingdom (UK) and Ireland (IRE) was assessed using negative binomial and zero-inflated negative binomial models on the entire 2014-2015 UK/IRE foal crops (Â = 28,282). Unassigned: In total, 6666 and 9456 horses raced in UK/IRE flat r...
Wilson AJ, Rambaut A.Horse racing is a multi-million pound industry, in which genetic information is increasingly used to optimize breeding programmes. To maximize the probability of producing a successful offspring, the owner of a mare should mate her with a high-quality stallion. However, stallions with big reputations command higher stud fees and paying these is only a sensible strategy if, (i) there is a genetic variation for success on the racecourse and (ii) stud fees are an honest signal of a stallion's genetic quality. Using data on thoroughbred racehorses, and lifetime earnings from prize money (LE) as a ...
McDonnell SM, Freeman DA, Cymbaluk NF, Schott HC, Hinchcliff K, Kyle B.To compare quantitative measures and clinical assessments of behavior as an indication of psychologic well-being of stabled horses provided drinking water continuously or via 1 of 3 intermittent delivery systems. Methods: 22 Quarter Horse (QH) or QH-crossbred mares and 17 Belgian or Belgian-crossbred mares (study 1) and 24 QH or QH-crossbred mares and 18 Belgian or Belgian-crossbred mares (study 2). Methods: Stabled horses were provided water continuously or via 1 of 3 intermittent water delivery systems in 2 study periods during a 2-year period. Continuous 24-hour videotaped samples were used...
Wilson M, Williams J, Montrose VT, Williams J.Most stallions within breeding programmes are expected to breed and compete concurrently. The exercising of stallions with regards to training regimes during the breeding season is a controversial subject. Daily exercise at low intensities is important for the mental and reproductive well-being of the stallion, however higher intensities of exercise, as seen in competing stallions, may have detrimental effects on seminal quality. To calculate if competition does affect semen quality, this study investigated the effect that equestrian discipline and timing of competition had on a range of stall...
van Proosdij R, Frietman S.Geriatric horses (>15 years) represent a substantial proportion of the equine population. The objective of this study was to (1) report on the cause of death in geriatric horses on a single retirement centre, (2) to evaluate the relationship between PPID status, and mortality rate. Data of 194 horses was collected over an eight-year period. This providing data for 80 geriatric cases of mortality. The average age of horses that died was 26.2 years (±4.8 years). The majority (95%) of mortalities were euthanised, most frequently due to colic (20%), old age (19%), and lameness (15%). Overall m...
Hodgson S, Bennett-Skinner P, Lancaster B, Upton S, Harris P, Ellis AD.These studies assessed the pressure forces exerted by horses to extract forage from haynets. Study 1 measured horse posture and pressure in Newtons (10 N = 1 kg Force) exerted on haynets when feeding from either a single (SH) or double layered (DH) haynet (3 kg Hay), hung low or high. Mean and maximum pull forces were higher for the DH vs. SH (DH: 81 ± 2 N, max 156 N; SH: 74 ± 2.9 N, max 121 N; p < 0.01). Horses pulled harder on low (max pull 144 ± 8 N) compared to high (109 ± 8 N; p < 0.05) hung haynets. Mean maximum angles (nose-poll-withers) recorded were 90° ± 9 for SH and 127Â...
MacKechnie-Guire R, Fisher M, Pfau T.Using a half pad beneath a saddle can be beneficial for improving saddle fit. However, there is a paucity of evidence on half pad use when used beneath a correctly fitted saddle. The aim was to quantify the effect that three different half pads have on pressure distribution beneath a saddle fitted following industry guidelines. Twelve nonlame horses were ridden by experienced riders in sitting trot and canter on each rein (three repeats). Saddle fit, with a high-withered cotton saddle cloth (control) compared with three half pads (viscoelastic gel, wool, and medical-grade, closed-cell foam), w...
Durando MM, MacKay RJ, Staller GS, Cooper BJ, Ginn PE, Meneghetti N.Septic cholangiohepatitis was diagnosed in an 11-year-old Warmblood gelding with a history of intermittent colic and fever. Klebsiella pneumoniae, susceptible to gentamicin, was cultured from the biopsy specimen. However, treatment with gentamicin was unsuccessful, and histologic examination and bacteriologic culture of a biopsy specimen obtained 3 weeks later revealed progression of the hepatic inflammation and yielded growth of gentamicin-resistant K pneumoniae. At this time, several discrete hyperechoic structures, suggestive of biliary calculi, were seen ultrasonographically. A change in a...
Burke CJ, Whishaw IQ.Spontaneous locomotor behavior in a novel space reveals insights into an animal's world view or Umwelt. For example, in many animal species, spontaneous behavior in a novel environment is parsed into activities at a home base and excursions from the home base. Domestic horses (Equus ferus caballas) are frequently ridden for recreation or in performance events in an equestrian arena but there has been no description of horse behavior in an arena when they are unconstrained and "exploring" or when moving freely under saddle. The present examination of exploration provides insights into horse ada...
Hesta M, Shepherd M.Inappropriate nutrition is a priority welfare challenge. Nutritional mistakes are common and can lead to adverse events, such as poor growth and performance, colic, laminitis, and obesity. A detailed nutritional assessment involving evaluating the equine patient, current diet/ration, and management is essential in creating an effective nutritional plan. Goal(s) should be established and used to inform the plan. Management or resource barriers should be considered. Effective communication and a team-based approach versus an authoritarian one are likely to enhance the success of the nutritional ...
Lindinger MI.Horses that sweat for prolonged periods lose considerable amounts of water and electrolytes. Maintenance of hydration and prevention of dehydration requires that water and electrolytes are replaced. Dehydration is common in equine disciplines and can be avoided, thus promoting equine wellness, improved performance and enhanced horse and rider safety. Significant dehydration occurs through exercise or transport lasting one hour or more. Oral electrolyte supplementation is an effective strategy to replace water and electrolytes lost through sweating. The stomach and small intestine serve as a re...
Cameron A, Longland A, Pfau T, Pinnegar S, Brackston I, Hockenhull J, Harris PA, Menzies-Gow NJ.This work aimed to determine the effect of strip grazing on physical activity in ponies using behavioral observations alongside accelerometers positioned at the poll. In study one, ten British native breed ponies were randomly assigned to paddock A (50 × 110 m) or B (50 × 110 m divided into seven equal strips with access to one additional strip per day) for seven days (n = 5/paddock). In study two, ten different British native breed ponies were randomly assigned for 14 days individually to (1) a control field where the animal was allowed complete access to their allotted area (n = 4)...
Putnam JR, Holmes LM, Green MJ, Freeman SL.Lameness is a common problem in the horse. Despite this, information on the incidence of lameness in horses in the UK is restricted to studies of lameness in performance horses, racehorses or referral hospital populations. Objective: To determine the overall incidence and common causes of lameness in a working horse population and incidence, duration and outcome of conditions observed. Methods: Prospective questionnaire study. Methods: Questionnaires were used to record lameness episodes in 294 horses in an equine military establishment. Information recorded included age, years of service, typ...
Pfister JA, Stegelmeier BL, Cheney CD, Ralphs MH, Gardner DR.Locoweed (Oxytropis sericea) is a serious poisoning problem for horses grazing on infested rangelands in the western United States. Our objectives were to determine 1) whether lithium chloride or apomorphine would condition aversions to palatable foods, and at what doses, and 2) whether horses could be averted to fresh locoweed in a pen and grazing situation. Apomorphine was not an acceptable aversive agent because at the dose required to condition an aversion (> or = 0.17 mg/kg BW), apomorphine induced unacceptable behavioral effects. Lithium chloride given via stomach tube at 190 mg/kg BW...
Kim SH, Lee JS, Lee JH, Kim YJ, Choi JG, Lee SK, Kim HJ, Yang SJ, Park T, Lee SK, Kang HE, Jeoung HY, Park JY.Venereal diseases caused by bacteria are important to the equine industry due to economic losses caused by decline of conception rate in breeding horses. Therefore, identification of infected animals as well as the implementation of appropriate managerial procedures based on accurate diagnosis is critical. In this study, two types of multiplex real-time polymerase chain reaction with high sensitivity and specificity were developed for the simultaneous detection and differentiation of five commonly associated bacterial pathogens of venereal diseases in horses, consisting of Taylorella equigenit...
Jaqueth AL, Turner TR, Iwaniuk ME, McIntosh BJ, Burk AO.Warm season wear-tolerant turfgrasses, such as those used on golf courses and athletic fields, may be valuable forages on equine operations because of their potential to remain viable during heavy hoof traffic. Crabgrass may also be suitable as it thrives in conditions where other grasses have limited success. The objective of this study was to assess the relative traffic tolerance and nutritional composition of five warm-season (WS) turfgrass cultivars of bermudagrass and zoysiagrass and one WS forage-type crabgrass. All cultivars were established by seed in replicated monoculture plots. Simu...
Rankins EM, Malinowski K.The New Jersey horse racing industry has declined over the last 5 years as indicated by decreases in the number of racing days, stallions standing, mares bred, and foals registered. These changes were hypothesized to have potential negative consequences for veterinary practices. The objective of the survey was to investigate changes in veterinary practice revenue and staff over a five-year period. Members of the New Jersey Association of Equine Practitioners completed a survey detailing their involvement in the horse racing industry and breeding of racehorses. A response rate of 49% was achiev...
Stojiljkovic N, Leroux F, Bubanj S, Popot MA, Paris A, Tabet JC, Junot C.There is an urgent need to implement holistic and untargeted doping control protocols with improved discriminatory power, compared to conventional methods that only target doping agents. Metabolomics, which aims to characterize all metabolites present in biological matrices, could fulfill this need. In this context, the aim of this study was to evaluate the impact of environmental factors on the ability to obtain a metabolic signature of stanozolol administration in horse doping situation. Urine samples from 16 horses breeded in two different places were collected over a one-year period, befor...
Lofgren EA, Rice BMG, Brady CM.Horse welfare is a sensitive topic that often results in a variety of strong feelings when discussed in the horse-owning public. This study used a scenario-based questionnaire in a positive psychology approach to assess the public's feelings and discussions about horse welfare. Results indicated themes in important welfare qualities such as turnout, shelter, and ability to express natural behaviors, as well as a positive discussion about welfare. This study provides future implications for further research techniques in this area as well as communicative strategies surrounding equine welfare p...
Miller SK.1. Results of laboratory experiments which compared horse and human serum butyrylcholinesterase (EC 3.1.1.8) with respect to their acid inactivation and ammonium sulfate protection show: 2. Horse serum butyrylcholinesterase is more resistant to inactivation at pH 3.0 than human serum butyrylcholinesterase. 3. The loss of activity at pH 3.0 for both horse and human butyrylcholinesterase does not follow first order kinetics. 4. Both human and horse serum butyrylcholinesterase are protected from pH 3.0 inactivation by ammonium sulfate concentrations up to 33% saturation (1.37 M).
