Observational studies in horses involve systematically assessing and recording behaviors, conditions, or other characteristics without manipulating the study environment. These studies provide insights into natural equine behaviors, health conditions, and interactions with their environment. Researchers often focus on aspects such as herd dynamics, feeding patterns, or responses to environmental changes. The data collected can help identify trends, correlations, and potential risk factors for certain conditions. This page compiles peer-reviewed research studies and scholarly articles that explore various observational methodologies and their applications in understanding equine behavior and health.
Jovanović V, Vučinić M, Voslarova E, Nenadović K.In Serbia, at present, there is very little information about the welfare of horses. The aim of this study was to identify the main welfare issues likely to be encountered in five different categories of horses (Western riding horses, riding school horses, leisure horses, jumping horses, and endurance horses) kept in stabled housing systems. A total of 50 horses were evaluated using the Animal Welfare Indicator (AWIN) welfare assessment protocol for horses. Identified welfare issues in horses were inadequate box dimensions (52%, 26/50), insufficient quantity of bedding material (34%, 17/50), d...
Meiseberg LK, Delarocque J, de Buhr N, Ohnesorge B.Equine asthma is a common, non-infectious, chronic lung disease that affects up to 80% of the horse population. Strict phenotyping and identification of subclinically asthmatic horses can be challenging. The aim of this study was to describe equine asthma phenotypes (mild, moderate, and severe asthma) defined by BALF cytology and occurrence of clinical signs in a population of privately owned horses and to identify the variables and examination steps with best discriminative potential. The standardised examination protocol included clinical examinations, blood work, airway endoscopy with bronc...
Mata F, Franca I, Araújo J, Paixão G, Lesniak K, Cerqueira JL.Hoof trimming and shoeing determine the horse's hoof shape and balance. Hoof conformation plays a crucial role in limb biomechanics and can consequently prevent or predispose to injury. This study investigated the relationship between the morphometric characteristics of the horse's hoof, specifically, the dorsal hoof wall angle (DHWA), the coronet band circumference (CBC), and lameness in 73 horses categorised as undertaking either show jumping, dressage, or riding school activities. Results from logistic regression indicated that horses with either a combination of acute DHWA with large CBC, ...
The increasing interest in the study of spontaneous (SY) and contagious yawning (CY) was so far focused on several taxa, especially primates. Here, we focused on SY and CY in horses, a suitable species due to their complex social dynamics that has been largely overlooked in research on these phenomena. By analyzing videos of 48 horses on pasture, we identified 2 yawning morphologies: Covered ( ) and Uncovered Teeth ( ). Using EquiFACS, we quantitatively demonstrated that and differ in terms of muscle recruitment. Moreover, we provide the first evidence for the presence of CY by comparing 2...
McDonald S, Harley JJ, Hockenhull J.Free-ranging native Dartmoor and Exmoor ponies have not only held strong cultural and environmental significance for thousands of years within their respective national parks, but their environmental benefits and naturally selected characteristics have also been acknowledged and harnessed for conservation grazing and rewilding programmes. Despite a wealth of literature regarding the welfare of sports, leisure and working horses, there is little information concerning the welfare of free-ranging and extensively grazing ponies. The present study compared the welfare of native Exmoor and Dartmoor...
Aoun R, Takawira C, Lopez MJ.To provide an overview of available research about effects of horseshoes on equine kinetics and kinematics. Methods: The terms, "horse/equine," "hoof," "shoes/horseshoes," "kinetics," and "kinematics" were searched in PubMed, Web of Science, Center for Agriculture and Bioscience International, and United States Department of Agriculture National Agricultural Library for manuscripts from first availability to 2024. Independent reviewers used preferred reporting items for systematic reviews and meta-analyses guidelines to map and extract evidence-based data from sources. Metrics included partici...
Nyerges-Bohák Z, Kovács L, Povázsai Á, Hamar E, Póti P, Ladányi M.Equine asthma in severe form (severe equine asthma [sEA]) shares remarkable similarities with human asthma. Human studies detected changes in the autonomic nervous system function in asthmatic patients based on heart rate variability (HRV) analysis. Methods: Observational study. Objective: To investigate the relationship between sEA and HRV in horses. Methods: Twenty horses diagnosed with sEA and 20 asymptomatic (non-sEA) horses were investigated. SEA horses showed clinical signs. The RR intervals of the ECG were recorded for 1 h at rest between 9 AM and 11 AM using a heart rate (HR) mon...
Tranquille CA, Chojnacka K, Murray RC.There has been little investigation into the health patterns of the eventing horse population outside veterinary clinics. To target health problems in the eventing horse population, it is important to determine the relative impact of different health problems. The objectives were to describe the prevalence and patterns of lameness/illness in registered British eventing horses. An online survey was released for all horses registered with British eventing in 2018. Data were collated and descriptive analyses undertaken. A total of 1677 surveys were completed, among which 49.4% reported a previous...
Haase L, Sedlmayr B, Jung IC, Sedlmayr M, Monett D, Winter J.Existing research agrees that a well-thought design of the user interface is a key point for an mHealth application for animal owners, supporting them obtain information and make decisions regarding their pet's specific situation. However, there is currently a lack of specific advice on the design of such an application. Methods: As part of a user-centered design (UCD) process, a formative, explorative usability test with n = 5 users was conducted for collecting design ideas. The test was conducted for two applications that were already available on the market. Results: The need of supporting ...
Laleye BOFV, Seye M, Chiavaccini L.Limited knowledge exists on recognition and treatment of equine abdominal pain in low- and middle-income countries. This study aimed at finding indicators for recognizing abdominal pain, evaluating responses to clinical and behavioral changes, and assessing the impact of timely referral on colic outcomes in a suburban region of Senegal. The final goal was to identify factors that may be leveraged to improve the outcome of horses presented for abdominal pain in Senegal. Unassigned: Retrospective, observational cohort study. Unassigned: Data from 26 foals and 40 adult horses referred for acute a...
Kim LD, Kreitner K, Scott DM, Seabaugh K, Duncan CG, Magzamen S.Limited research exists on impacts of air pollution on non-human mammals, particularly animal athletes such as Thoroughbred racehorses. Athletes have a greater risk of exposure as heightened exertion and increased airflow carry more pollutants deeper into the respiratory tract. Objective: To provide insights into the impact of ambient air pollution, particularly fine particulate matter (PM), on race speed. Methods: Retrospective observational study. Methods: Data were obtained from The Jockey Club Information Systems, covering 31 407 winning races by Thoroughbred horses in California spannin...
Peters BC, Gabriels RL, Schmid AA, Pan Z, Merritt T, Hoffman A, Hepburn S.The current paper aimed to assess the feasibility of a modified intervention protocol named "Occupational Therapy using Zones of Regulation Concepts in an Equine Environment" (OT-ZOR Equine). Unassigned: A single arm A-B feasibility study was conducted, involving 14 autistic youth ages 6-13 years who first received 10-weeks of occupational therapy without horses (OT-ZOR Clinic) followed by 10-weeks of OT-ZOR Equine. Unassigned: All participants completed the study and attended 95% of OT-ZOR Equine sessions. Occupational therapists maintained 91% fidelity to the OT-ZOR Equine intervention proto...
Grandgeorge M, Lerch N, Delarue A, Hausberger M.Equine-assisted intervention (EAI) studies deal with clients, whereas very few studies focused on the effects on animals. EAI equids are also submitted to management, which influences their welfare. Management and working conditions depend on human decisions and perception. We gathered information through a survey about facilities managers' strategies (n = 51) and obtained direct information on management and working practices and their consequences on equids' welfare through an observational study (n = eight facilities, 174 equids). Differences in managers' perceptions of good management prac...
Kreuzer L, Naber A, Zink R, Millesi E, Palme R, Hediger K, Glenk LM.Research on equine-assisted therapy (EAT) has primarily been centered on human health. Relatively few studies have addressed the impact of EAT on horses. This study sought to monitor four experienced therapy horses' cardiovascular and glucocorticoid activity over the course of standardized EAT sessions designed to support women with intellectual disability. In the control condition, horses completed the EAT protocol solely with the therapist, thereby resembling a training session. Descriptive data analysis revealed higher levels of heart rate during an experimental EAT session and increased sa...
Dwyer J, Roshier AL, Campbell M, Hill B, Freeman SL.Weaning represents one of the most stressful events in the life of a horse, and may have long-term impacts on behaviour. There are a range of approaches used to wean foals from mares, including abrupt and progressive separation methods. There is currently a lack of consensus on how stress and impact are measured. Objective: To conduct a scoping review to identify and chart measures of weaning-related stress on the mare and foal. Methods: Scoping review. Methods: The scoping review was conducted using the PRISMA extension for scoping reviews. Systematic searches were conducted in three scientif...
Watney M, Lancaster B, Randle H.The aims of this study were to first determine the extent of owners' fundamental knowledge of equine care, second, gain their opinions on the implementation of a mandatory certificate of knowledge and third, to investigate the association of certification on horse owner knowledge. An online survey comprising 23 questions (18 closed, 5 open) was distributed worldwide via snowball sampling, and completed by 1847 horse owners who were all ≥18 years old from 17 different countries. Almost all (96%, n = 1781) completed surveys were usable. Just over half (52%) of participants held a curre...
Fiedler JM, Ayre ML, Rosanowski S, Slater JD.Anthropomorphizing can misinform the making of inferences about animal mental experiences. This is a consideration when implementing the Five Domains Model for animal welfare assessment. An online survey run in 2021 captured horse sector participants' perspectives about anthropomorphism and wellbeing in relation to horses. Most respondents, 82.9% ( = 431/520), believed that anthropomorphism could influence horse welfare and wellbeing. These respondents were then asked how, in their opinion, anthropomorphism might relate to horse welfare. A thematic analysis identified two themes: (1) 'Anthropo...
Bonilla Lemos Pizzi GL, Holz K, Kowalski ÉA, Fonseca Ribeiro P, Blake R, Ferreira Martins C.The esbarrada and volta sobre patas manoeuvres are critical in Criollo horse equestrian activities, yet their kinematics remain largely unexplored. This observational study aimed to kinematically describe the manoeuvres in Criollo breed horses and explore the relationship between static goniometry and dynamics. A 2D kinematic analysis was conducted on 31 Criollo horses performing the manoeuvres using high-speed cameras. Joint angles were measured using static goniometry and analysed in relation to dynamic performance. The esbarrada covered a distance of 4.28 ± 0.99 m in 1.15 ± 0.11 s at a ve...
Nankervis K, Tranquille C, Tacey J, Deckers I, MacKechnie-Guire R, Walker V, Hopkins E, Newton R, Murray R.Repeated exposure to water treadmill (WT) exercise could elicit kinematic responses reflecting adaptation to WT exercise. The study's aim was to compare the responses of a group of sport horses to a standardised WT exercise test (WTSET) carried out at three time points, week 0 (n = 48), week 20 (n = 38), and week 40 (n = 29), throughout a normal training programme incorporating WT exercise. Horses were recruited from the existing client populations of two commercial water treadmill venues for the purpose of this longitudinal, observational study. Limb, back, poll, wither, and pelvic kinematics...
Johns LT, Smythe MP, Dewberry LS, Staiger EA, Allen K, Brooks SA.In international equestrian sport, visual inspections assess gait and lameness to protect the welfare of performance horses during competition. Horses competing internationally in three-day eventing must pass two mandatory inspections (pre-competition and post-cross country) before attempting the final phase: the jumping test (JT). We hypothesized that digitally quantifying objective gait parameters captured during the two mandatory inspections will identify locomotor characteristics that predict success during the jumping test. Utilizing the DeepLabCut (DLC) software package for labeling of a...
Flores JEM, Terrazas A, Lara Sagahon AV, Aleman M.Parasympathetic tone activity (PTA) in response to nociceptive stimulus in conscious non-sedated horses is unknown. Objective: Study PTA, heart rate (HR), and horse grimace scale (HGS) at rest and during mechanical nociceptive stimulation. Methods: Ninety healthy young adult horses (females, males): 30 each of Friesians, Quarter Horses, and Warmbloods. Methods: Prospective control study. The study consisted of habituation to equipment (Day 1), baseline recordings (Days 2 and 3), and nociceptive testing applying mild pressure to the metacarpus (Day 4). Parasympathetic tone, HR, and HGS were rec...
Marunova E, Hernlund E, Persson-Sjödin E.Head and pelvis vertical movement asymmetries in horses are often evaluated under different conditions yet better understanding is required of how these asymmetries are altered by factors such as surface type or circle size. This study investigated how stride duration, surface and lungeing in circles of different sizes influenced objectively measured head and pelvis movement asymmetries in riding horses in full training. Movement asymmetries were recorded with body mounted accelerometers and were based on the differences between the two vertical displacement minima or maxima of head (HDmin, HD...
McGill S, Coleman R, Hayes M.Indoor arenas do not always include mechanical ventilation or stirring fans and occupancy by horses and humans can be sporadic and inconsistent, which creates a challenging space for understanding and predicting variations in temperature, moisture, and airflow. To understand the interior environment within indoor arenas, monitoring was conducted at 15 facilities within 200 kilometres of Lexington, KY. Environmental monitoring of dry bulb temperature, relative humidity, dew point temperature, air speeds, and solar radiation took place over 7 days in the winter and summer to examine temporal var...
Werner LC, de Oliveira GM, Daros RR, Costa ED, Michelotto PV.The use of grimace scales enables the clinical identification of changes in the facial expressions of animals caused by pain. The Horse Grimace Scale (HGS) is one such tool, comprising a pain coding system based on facial expressions and assessing six Facial Action Units (FAUs). Each FAU is accompanied by descriptions and anatomical details to assist the evaluator. However, the morphological descriptions for certain FAUs in the HGS are not sufficiently detailed, potentially hindering accurate interpretation. This study is an analytical investigation aimed at enhancing the morphoanatomical deta...
Long M, Grimm H, Jenner F, Cavalleri JV, Springer S.Quality of life (QoL) provides a comprehensive concept underpinning veterinary decision-making that encompasses factors beyond physical health. It becomes particularly pertinent when seeking responsible choices for chronically ill or old horses that emphasise their well-being and a good QoL over the extension of life. How different stakeholders use the concept of QoL is highly relevant when considering the complexity of these decisions in real-life situations. Methods: Seven focus group discussions (N = 39) were conducted to gain insights into how stakeholders assess and use equine QoL in ...
Herbst AC, Coleman MC, Macon EL, Harris PA, Adams AA.Information on health care and health status of U.S. senior horses (≥15 years of age) is currently sparse. Objective: (A) Provide an overview of owner-reported (1) medical conditions, (2) management/treatment practices for equine metabolic syndrome and pituitary pars intermedia dysfunction (PPID), (3) frequencies of routine health care practices and (4) supplement and pharmaceutical use in U.S. senior horses (≥15 years of age). (B) Evaluate potential risk factors for certain medical conditions and for low routine health care. Methods: Online survey. Methods: Descriptive and inferential...
Elzahaby D, Mirra A, Levionnois OL, Spadavecchia C.Inhalational anaesthetic agents are routinely used in veterinary anaesthesia practices, yet their consumption contributes significantly to greenhouse gas emissions and environmental impact. We conducted a 55-day observational study at a veterinary teaching hospital in Switzerland, monitoring isoflurane and sevoflurane consumption across small, equine and farm animal clinics and analysed the resulting environmental impact. Results revealed that in total, 9.36 L of isoflurane and 1.27 L of sevoflurane were used to anaesthetise 409 animals across 1,489 h. Consumption rates varied among species...
Peat FJ, Kawcak CE, McIlwraith CW, Berk JT, Keenan DP.Changes in the proximal sesamoid bones (sesamoids) and the insertional region of the adjacent suspensory ligament branch (branch) are of particular importance in young Thoroughbreds sold at public auction. Little is known about the prevalence of concurrent ultrasonographical branch change, relative to the various grades of radiological sesamoid appearance. Objective: To examine the existence of concurrent radiological and ultrasonographical findings in individual sesamoid-branch units in sales horses; to determine whether there are any radiological findings that are consistently accompanied by...
Stothart MR, McLoughlin PD, Medill SA, Greuel RJ, Wilson AJ, Poissant J.Gut microbiomes are widely hypothesised to influence host fitness and have been experimentally shown to affect host health and phenotypes under laboratory conditions. However, the extent to which they do so in free-living animal populations and the proximate mechanisms involved remain open questions. In this study, using long-term, individual-based life history and shallow shotgun metagenomic sequencing data (2394 fecal samples from 794 individuals collected between 2013-2019), we quantify relationships between gut microbiome variation and survival in a feral population of horses under natural...

Gmel AI, Haraldsdóttir EH, Serra-Bragança F, Lamas LP, Rosa TV, Stefaniuk-Szmukier M, Klecel W, Neuditschko M, Weishaupt MA.Horses have been used and bred for centuries for their movements. However, specific breeds are expected to have different movement capabilities. We have measured 425 horses from four different breeds at walk and trot on a straight line using an inertial measurement unit (IMU) system (EquiMoves®). This article describes how the data was collected, filtered and analysed to provide a useable dataset of 28 movement variables. It provides a full protocol for field measurements and requirements for adequate trials for analysis. Intra-class correlation coefficient estimates are also provided to asse...

Methods: Patients were identified using the term "sports injury-horse riding" from the departmental database for one calendar year from February 2000. Data were collected regarding demographics, injuries, protective clothing, and outcome. The data were then analysed and compared with the previously published literature. Results: 260 patients' records were analysed. The ...
Buhl R, Ersbøll AK, Eriksen L, Koch J.To evaluate changes over time in echocardiographic measurements in young Standardbred racehorses undergoing training and racing and determine whether there was any relationship between cardiac dimensions and racing performance. Methods: Longitudinal observational study. Methods: 103 horses. Methods: 2-dimensional and M-mode echocardiography was performed 4 times at 6-month intervals. Results: Significant cardiac enlargement took place during the study period as indicated by increases in left ventricular internal diameter in diastole (LVIDd), estimated left ventricular muscle mass (LV mass), an...
Proudman CJ.The records of 200 colic episodes, collected prospectively, over a two year period, from first opinion cases, were analysed and compared with a control sample selected at random from the same population. Analysis by colic type revealed 72% spasmodic/undiagnosed; 7% surgical; 5.5% flatulent; 5% pelvic flexure impactions; 9.5% other implications and 1% colitis. A possible predisposing cause was identified in 43% of the spasmodic/undiagnosed cases. The total incidence of colic in each age group showed no statistically significant differences from the control population. Stallions were significant...
Hausberger M, Fureix C, Bourjade M, Wessel-Robert S, Richard-Yris MA.Play remains a mystery and adult play even more so. More typical of young stages in healthy individuals, it occurs rarely at adult stages but then more often in captive/domestic animals, which can imply spatial, social and/or feeding deprivations or restrictions that are challenging to welfare, than in animals living in natural conditions. Here, we tested the hypothesis that adult play may reflect altered welfare states and chronic stress in horses, in which, as in several species, play rarely occurs at adult stages in natural conditions. We observed the behaviour (in particular, social play) ...
Christensen JW, Beekmans M, van Dalum M, VanDierendonck M.The effects of hyperflexion on the welfare of dressage horses have been debated. This study aimed to investigate acute stress responses of dressage horses ridden in three different Head-and-Neck-positions (HNPs). Fifteen dressage horses were ridden by their usual rider in a standardised 10-min dressage programme in either the competition frame (CF), hyperflexion ("Low-Deep-and-Round"; LDR) or a looser frame (LF) in a balanced order on three separate test days. Heart rate (HR), heart rate variability parameters (HRV), behaviour and rein tension were recorded during the test. Salivary cortisol c...
Landman MA, de Blaauw JA, van Weeren PR, Hofland LJ.A population of 805 horses (70 per cent dressage, 20 per cent show jumpers and 10 per cent trotters) with orthopaedic problems was examined for signs of lameness and back problems, irrespective of their original complaints. In the horses with a back problem the prevalence of lameness was 74 per cent, and back problems were diagnosed in 32 per cent of the lame horses. These percentages were significantly higher than those recorded in a control population of 399 horses, of which 20 per cent were lame and 12 per cent had back problems. In the group of horses with orthopaedic problems there was a ...
Anderson S, Meints K.Equine-assisted activities and therapies are increasing in popularity for treatment of ASD symptoms. This research evaluated effects of a 5-week programme of therapeutic riding on social functioning of children/adolescents (N = 15) with ASD. The effectiveness of the programme was evaluated using the autism spectrum quotient, the Vineland Adaptive Behaviour Scale and the empathising and systemising quotient. Results established that the TR intervention increased empathising and reduced maladaptive behaviours. The findings also indicated that specific adaptive behaviours like socialization and...
Trösch M, Pellon S, Cuzol F, Parias C, Nowak R, Calandreau L, Lansade L.Animals can indirectly gather meaningful information about other individuals by eavesdropping on their third-party interactions. In particular, eavesdropping can be used to indirectly attribute a negative or positive valence to an individual and to adjust one's future behavior towards that individual. Few studies have focused on this ability in nonhuman animals, especially in nonprimate species. Here, we investigated this ability for the first time in domestic horses (Equus caballus) by projecting videos of positive and negative interactions between an unknown human experimenter (a "positive" ...
Souris AC, Kaczensky P, Julliard R, Walzer C.The Przewalski's horse (Equus ferus przewalskii) became extinct in the wild in the 1960s, but survived as a species due to captive breeding. There have been several initiatives to re-introduce the species in central Asia, but until now only two projects in Mongolia establish free-ranging populations. Data on basic ecology and behavior of the species prior to extinction is largely lacking and a good documentation of the re-introduction process is essential. Between 13 May and 2 September 2003 we documented the time budget-, group synchrony and body score development of a newly released Przewals...
Potter SJ, Bamford NJ, Harris PA, Bailey SR.To determine the prevalence of obesity within a population of pleasure horses and ponies in Victoria, Australia, and to compare owners' perceptions of their animals' body condition with researchers' assessments. Methods: An observational study plus owner questionnaire. Methods: Ten Pony Club rallies in different regions of Victoria were attended. Information regarding 229 horses and ponies were obtained from owner questionnaires, and owners' perceptions of the current body condition of their animals were assessed using a visual analogue scale. Body condition score (BCS) was assessed by the res...
Richard EA, Depecker M, Defontis M, Leleu C, Fortier G, Pitel PH, Couroucé-Malblanc A.Multiple cytological patterns occur in bronchoalveolar lavage fluid (BALF) of horses with inflammatory airway disease (IAD). Only few data on BALF cytokine profiles are available for horses with IAD, and are limited to mRNA expression. Objective: Cytological profiles of IAD are associated with different BALF immunological pathways. To investigate BALF cytokine concentrations in a large number of horses with neutrophilic IAD. Methods: One hundred and thirty-eight client-owned Standardbred racehorses in active training. Methods: Prospective observational study. BALF samples were obtained from le...
Ireland JL, McGowan CM, Clegg PD, Chandler KJ, Pinchbeck GL.This study reports on aspects of preventive health care and on the prevalence of disease in geriatric (≥30 years old) horses and ponies in North-West England and North Wales. Of 128 questionnaires mailed to horse owners, 87 useable responses were received and 69 horses were subject to veterinary examination. Of the animals examined, 16% were underweight with body condition scores (BCS)3/5). This contrasted with the owner responses that reported 23% of the animals surveyed to be underweight and only 3% to be overweight. When assessed at trot, 77% of the horses were lame on at least one limb, ...
Nathan H, Gloobe H.The myocardial fibres of the posterior wall of the atrio-venous junctions were examined in 35 large domestic mammals. In the majority of specimens a common pattern in the course and organization of the fibres could be observed. The most obvious features were the following: (1) a main circular fascicle surrounding the pulmonary trunks; (2) fibres encircling the atriovenous junctions; and (3) myocardial sleeves extending along the veins, occasionally as far as the lung. The superior part of the left atrial wall was consistently thicker than the inferior section. Individual variations of this wal...
Soroko M, Howell K, Dudek K.The aim of the study was to describe the dependence on ambient temperature of distal joint temperature at the forelimbs of racehorses. The study also investigated the influence of differing ambient temperatures on the temperature difference between joints: this was measured ipsilaterally (i.e. between the carpal and fetlock joints along each forelimb) and contralaterally (i.e. between the same joints of the left and right forelimbs). Sixty-four healthy racehorses were monitored over 10 months. At each session, three thermographic images were taken of the dorsal, lateral and medial aspects of t...
Lanning BA, Baier ME, Ivey-Hatz J, Krenek N, Tubbs JD.Quality of life assessments were used in this study to determine the behavioral changes of children diagnosed with autism spectrum disorder (ASD) who participated in equine assisted activities. Behavioral changes of children with ASD participating in 9 weeks of equines assisted activities (EAA) (N = 10) were compared to behavioral changes of children who participated in a non-equine intervention (N = 8). Parents noted significant improvements in their child's physical, emotional and social functioning following the first 6 weeks of EAA. The children participating in the non-equine program also...
Riihimäki M, Raine A, Elfman L, Pringle J.Airborne factors in a conventionally managed racing stable and markers of pulmonary inflammation in the stabled horses were investigated on 3 occasions at 6-month intervals, including 2 winter periods and the intervening summer period. The stable measurements included inside and outside ambient temperature and relative humidity, levels of total and respirable dust, endotoxin, and 1,3-beta-glucan. Horses (n = 12) were examined in detail clinically as well as by endoscopy, bronchoalveolar lavage (BAL) cytology, and real-time polymerase chain reaction (RT-PCR) analysis of BAL-cells for IL-6 and I...
Martin BB, Klide AM.The diagnosis of back pain is often a diagnosis of exclusion of other problems in the face of poor performance. It requires careful observation, thought, an open mind, and experience. The signs of back pain can be extremely variable and range from subtle to obvious. Obvious forelimb or hind limb lameness is not usually a sign of back pain. The most common differential diagnosis may be back pain secondary to degenerative joint disease of the hocks, fetlocks, or stifle. These diseases can mimic signs of back pain including lack of impulsion, shortening of the stride length, and change in the str...
Lloyd RG.All horse-related injuries presenting to an Accident Service over a two-year period were investigated. 237 patients presented. The injuries were not considerable in absolute number but were in severity. There was a high morbidity with 22% of all patients requiring admission to hospital, 50% of all admissions because of head injuries. At least seven life-threatening injuries were identified and there were other severe pelvic and spinal injuries. The wearing of protective head gear remains the most important safety measure.

Barber HM.Horse-riding is increasing in popularity. During 1971 and 1972 154 patients had horse-related injuries of sufficient severity to warrant admission to the Radcliffe Infirmary. The injuries sustained are more common and more severe than generally appreciated and are comparable to those sustained by motor-cyclists. Supervision of children is often insufficient and protective leg and head gear is commonly quite inadequate, even when worn.
Schemann K, Taylor MR, Toribio JA, Dhand NK.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...
Ireland JL, Clegg PD, McGowan CM, McKane SA, Pinchbeck GL.With growing numbers of aged horses, geriatric medicine is becoming increasingly important in equine veterinary practice; however, there is a paucity of information on the UK equine geriatric population. Objective: To describe the demographic characteristics of the equine geriatric population and to assess management practices undertaken by owners of geriatric horses (aged≥15 years). 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: Horses a...
Sutton GA, Dahan R, Turner D, Paltiel O.A validated tool for assessing the severity of acute abdominal pain is needed for the effective management of colic in horses. Two behaviour-based colic pain scales were constructed by combining together mathematical and judgemental approaches. The mathematical approach identified easily-recognised pain behaviours to select as items. The judgemental approach further modified the items and weighted them based on expert-opinion. Thirty equine practitioners assessed the level of pain demonstrated in 23 film clips of clinical cases exhibiting signs of acute abdominal pain prospectively using a 10c...
Parkin TD.This article describes the development of epidemiologic analyses of racetrack injury in racehorses. The risk or rate of fatal and nonfatal injury in racing and training around the world is examined. The focus is on the importance of global collaboration and the identification of modifiable risk factors. In particular, exercise-related risk factors for injury are evaluated and the potential impact of interventions discussed.
Hintze S, Smith S, Patt A, Bachmann I, Würbel H.Finding valid indicators of emotional states is one of the biggest challenges in animal welfare science. Here, we investigated in horses whether variation in the expression of eye wrinkles caused by contraction of the inner eyebrow raiser reflects emotional valence. By confronting horses with positive and negative conditions, we aimed to induce positive and negative emotional states, hypothesising that positive emotions would reduce whereas negative emotions would increase eye wrinkle expression. Sixteen horses were individually exposed in a balanced order to two positive (grooming, food antic...
Mach N, Ruet A, Clark A, Bars-Cortina D, Ramayo-Caldas Y, Crisci E, Pennarun S, Dhorne-Pollet S, Foury A, Moisan MP, Lansade L.We simultaneously measured the fecal microbiota and multiple environmental and host-related variables in a cohort of 185 healthy horses reared in similar conditions during a period of eight months. The pattern of rare bacteria varied from host to host and was largely different between two time points. Among a suite of variables examined, equitation factors were highly associated with the gut microbiota variability, evoking a relationship between gut microbiota and high levels of physical and mental stressors. Behavioral indicators that pointed toward a compromised welfare state (e.g. stereotyp...
Fureix C, Pagès M, Bon R, Lassalle JM, Kuntz P, Gonzalez G.Handling is a crucial component of the human-horse relationship. Here, we report data from an experiment conducted to assess and compare the effect of two training methods. Two groups of six Welsh mares were trained during four sessions of 50 min, one handled with traditional exercises (halter leading, grooming/brushing, lifting feet, lunging and pseudo-saddling (using only girth and saddle pad) and the second group with natural horsemanship exercises (desensitization, yielding to body pressure, lunging and free-lunging). Emotional reactivity (ER) and the human-horse relationship (HHR) were as...
Ringhofer M, Yamamoto S.Some domestic animals are thought to be skilled at social communication with humans due to the process of domestication. Horses, being in close relationship with humans, similar to dogs, might be skilled at communication with humans. Previous studies have indicated that they are sensitive to bodily signals and the attentional state of humans; however, there are few studies that investigate communication with humans and responses to the knowledge state of humans. Our first question was whether and how horses send signals to their potentially helpful but ignorant caretakers in a problem-solving ...
Pfau T, Stubbs NC, Kaiser LJ, Brown LE, Clayton HM.To determine whether body lean angle could be predicted from circle radius and speed in horses during lunging and whether an increase in that angle would decrease the degree of movement symmetry (MS). Methods: 11 medium- to high-level dressage horses in competition training. Methods: Body lean angle, head MS, and trunk MS were quantified during trotting while horses were instrumented with a 5-sensor global positioning system-enhanced inertial sensor system and lunged on a soft surface. Speed and circle radius were varied and used to calculate predicted body lean angle. Agreement between observ...
Luna D, Vásquez RA, Rojas M, Tadich TA.Appropriate interventions to improve working equine welfare should be proposed according to scientific evidence that arises from different geo-cultural contexts. This study aims to assess and compare the welfare status of working horses in two administrative regions of Chile and to determine how owners perceive their horses. Horses' welfare status was assessed through direct indicators (direct observation and clinical examination) and indirect indicators (an interview with the owner). Owners' perceptions of their horses were determined through a discourse analysis of their statements. In total...
König von Borstel U, Glißman C.Rideability, i.e. the ease and comfort with which a horse can be ridden, is considered to be one of the most important traits in riding horses. However, at present rideability is evaluated rather subjectively in breeding horse performance tests. The aim of the present study was to evaluate the role horse behaviour as well as degree and quality of rein tension might play in judges' evaluation of horses' rideability. Mares (n=33) and stallions (n=13) from two different mare- and one stallion-testing station were observed twice during their performance test dressage training. During these rides, ...
