Topic:Welfare

Equine welfare encompasses the physical and psychological well-being of horses, focusing on their health, comfort, and overall quality of life. This area of study addresses various aspects, including nutrition, housing, behavior, and management practices, aiming to ensure that horses are kept in environments that meet their physiological and behavioral needs. Research in equine welfare examines factors such as stress indicators, pain assessment, and the impact of human interactions on horse behavior and health. This page compiles peer-reviewed research studies and scholarly articles that explore the assessment, improvement, and implications of welfare practices in equine management.
A Review of Equine Sleep: Implications for Equine Welfare.
Frontiers in veterinary science    August 17, 2022   Volume 9 916737 doi: 10.3389/fvets.2022.916737
Greening L, McBride S.Sleep is a significant biological requirement for all living mammals due to its restorative properties and its cognitive role in memory consolidation. Sleep is ubiquitous amongst all mammals but sleep profiles differ between species dependent upon a range of biological and environmental factors. Given the functional importance of sleep, it is important to understand these differences in order to ensure good physical and psychological wellbeing for domesticated animals. This review focuses specifically on the domestic horse and aims to consolidate current information on equine sleep, in relatio...
Single housing but not changes in group composition causes stress-related immunomodulations in horses.
PloS one    August 17, 2022   Volume 17, Issue 8 e0272445 doi: 10.1371/journal.pone.0272445
Schmucker S, Preisler V, Marr I, Krüger K, Stefanski V.Domestic horses are currently often subject to management practices that can entail social stressors, which in turn can negatively influence immunocompetence and disease susceptibility. The present study therefore aimed to characterize the number of various blood leukocyte subsets in horses, focusing on two potentially stressful housing environments: changes in group composition and relocation to individual stabling. Immune measurements were conducted before as well as one and eight days after changes were made. They were complemented by an assessment of plasma cortisol concentrations as well ...
Journeys, Journey Conditions, and Welfare Assessment of Unbroken (Unhandled) Horses on Arrival at a Slaughterhouse in Italy.
Animals : an open access journal from MDPI    August 15, 2022   Volume 12, Issue 16 2083 doi: 10.3390/ani12162083
Zappaterra M, Nanni Costa L, Felici M, Minero M, Perniola F, Tullio D, Padalino B.Transportation of horses to slaughterhouses can pose a welfare concern, in particular when horses are unbroken/unhandled. This study aimed to describe their journeys and journey conditions, document their welfare status on arrival in a slaughterhouse in Italy, and investigate possible associations between journey conditions and welfare issues. A total of 395 unbroken draft horses in 20 different consignments were assessed with a standardized protocol. The most common departure point (16/20 consignments, 80%) was a French assembly center, but many of these horses had Spanish passports, suggesti...
Non-contact respiratory measurement in a horse in standing position using millimeter-wave array radar.
The Journal of veterinary medical science    August 9, 2022   Volume 84, Issue 10 1340-1344 doi: 10.1292/jvms.22-0238
Matsumoto T, Okumura S, Hirata S.This study aimed to apply radar technology to a large quadruped animal. We first developed a non-contact respiration measurement system using millimeter-wave array radar for a horse in standing position. Specifically, we measured the respiration of a stationary domestic horse in stables. Simultaneously, we measured the respiration rate using infrared thermography and developed a method for analyzing the radar information while verifying the rate of agreement. Our results suggested that the radar technology detected breathing and accurately measured the respiration of a horse, despite variation...
Social Licence to Operate: What Can Equestrian Sports Learn from Other Industries?
Animals : an open access journal from MDPI    August 5, 2022   Volume 12, Issue 15 1987 doi: 10.3390/ani12151987
Douglas J, Owers R, Campbell MLH.The concept of 'social licence to operate' (SLO) is relevant to all animal-use activities. An SLO is an intangible, implicit agreement between the public and an industry/group. Its existence allows that industry/group to pursue its activities with minimal formalised restrictions because such activities have widespread societal approval. In contrast, the imposition of legal restrictions-or even an outright ban-reflect qualified or lack of public support for an activity. This review discusses current threats to equestrianism's SLO and suggests actions that those across the equine sector need to ...
An Initial Survey of Volunteer Perceptions of Horses in Equine-Assisted Services: Volunteer Experiences, Training, and Educational Needs.
Journal of equine veterinary science    July 29, 2022   Volume 117 104090 doi: 10.1016/j.jevs.2022.104090
Rudd C, Wheeler B, Pasiuk E, Schroeder K.Equine-Assisted Services (EAS) gained a foothold in the healthcare industry as a unique modality addressing the physical, cognitive, and psychological health issues for people across the lifespan. These services require a team approach, with volunteer support playing a prominent role in service delivery. Volunteers are a precious resource for EAS programs and step into a variety of support roles, including preparation and handling. However, little is known about the horse-volunteer relationship or factors that influence their working relationships. Therefore, the purpose of this web-based surv...
Horses’ attentional characteristics differ according to the type of work.
PloS one    July 25, 2022   Volume 17, Issue 7 e0269974 doi: 10.1371/journal.pone.0269974
Rochais C, Stomp M, Sébilleau M, Houdebine M, Henry S, Hausberger M.Attention is a central process of cognition and influences the execution of daily tasks. In humans, different types of work require different attentional skills and sport performance is associated with the ability to attention shift. Attention towards humans varies in dogs used for different types of work. Whether this variation is due to the recruitment of individuals suitable for specific types of work, or to the characteristics of the work, remains unclear. In the present study, we hypothesized that domestic horses (Equus caballus) trained for different types of work would also demonstrate ...
Horses wait for more and better rewards in a delay of gratification paradigm.
Frontiers in psychology    July 22, 2022   Volume 13 954472 doi: 10.3389/fpsyg.2022.954472
Brucks D, Härterich A, König von Borstel U.Self-control, defined as the ability to forgo immediate satisfaction in favor of better pay-offs in the future, has been extensively studied, revealing enormous variation between and within species. Horses are interesting in this regard because as a grazing species they are expected to show low self-control whereas its social complexity might be linked to high self-control abilities. Additionally, self-control may be a key factor in training and/or coping with potentially stressful husbandry conditions. We assessed horses' self-control abilities in a simplified delay of gratification test that...
Tool Use in Horses.
Animals : an open access journal from MDPI    July 22, 2022   Volume 12, Issue 15 1876 doi: 10.3390/ani12151876
Krueger K, Trager L, Farmer K, Byrne R.Tool use has not yet been confirmed in horses, mules or donkeys. As this subject is difficult to research with conventional methods, we used a crowdsourcing approach to gather data. We contacted equid owners and carers and asked them to report and video examples of "unusual" behaviour via a dedicated website. We also searched YouTube and Facebook for videos of equids showing tool use. From 635 reports, including 1014 behaviours, we found 20 cases of tool use, 13 of which were unambiguous in that it was clear that the behaviour was not trained, caused by reduced welfare, incidental or accidenta...
Quality of Life within Horse Welfare Assessment Tools: Informing Decisions for Chronically Ill and Geriatric Horses.
Animals : an open access journal from MDPI    July 17, 2022   Volume 12, Issue 14 doi: 10.3390/ani12141822
Long M, Dürnberger C, Jenner F, Kelemen Z, Auer U, Grimm H.Equine Quality of Life (QoL) is an important concern in decision making in veterinary medicine and is especially relevant for chronically ill or geriatric horses towards the end of their lives. To our knowledge, there is no currently available QoL assessment tool for chronically ill or geriatric horses that assesses equine QoL defined as the horse's evaluation of their life. However, tools exist to assess equine welfare in different contexts. Hence, the aims of this study were to analyse how equine welfare, QoL, well-being and happiness assessment tools label, define and operationalise the con...
Catastrophic Musculoskeletal Injuries in Thoroughbred Racehorses in Uruguay, 2011-2017.
Journal of equine veterinary science    July 9, 2022   Volume 117 104074 doi: 10.1016/j.jevs.2022.104074
Bimson NH, Morrice-West AV, Wong ASM, Hitchens PL, Rocca MR, Whitton RC.Catastrophic musculoskeletal injuries (CMI) pose a major welfare concern to horses and their riders, yet limited data are available describing their occurrence in South America. Using a retrospective cohort and case-control design, the objective of the study was to determine the incidence of CMI for Thoroughbreds in training and racing, and associated horse-level risk factors in Uruguay. Seventy-seven Thoroughbreds sustained a CMI, 37 of which were age- and sex-matched to 111 control horses in the same race. Training and racing data from 2011 to 2017 were collected. Incidence of race day CMI p...
Assessment of Welfare in Groups of Horses with Different Management, Environments and Activities by Measuring Cortisol in Horsehair, Using Liquid Chromatography Coupled to Hybrid Orbitrap High-Resolution Mass Spectrometry.
Animals : an open access journal from MDPI    July 6, 2022   Volume 12, Issue 14 doi: 10.3390/ani12141739
Cerasoli F, Podaliri Vulpiani M, Saluti G, Conte A, Ricci M, Savini G, D'Alterio N.Horses have always been animals used for companionship, work, transportation, and performance purposes over the history of humanity; there are different ways of managing horses, but studies on how horse welfare is influenced by different activities and managements are scanty. Understanding how the management, the environment, and the different uses of horses can affect the level of stress and well-being is important not only for people associated with horses. Three groups of horses with different management, environments, and activities were selected: (1) stabled horses ridden frequently, (2) ...
Does Feeding Management Make a Difference to Behavioural Activities and Welfare of Horses Reared for Meat Production?
Animals : an open access journal from MDPI    July 6, 2022   Volume 12, Issue 14 1740 doi: 10.3390/ani12141740
Raspa F, Tarantola M, Muca E, Bergero D, Soglia D, Cavallini D, Vervuert I, Bordin C, De Palo P, Valle E.Horses reared for meat production are generally fed a diet rich in starch with the aim of maximizing production performances. This study evaluated the effects of two feeding management systems on horse welfare by analysing the relative time spent engaged in different behavioural activities. Nineteen Bardigiano horses aged 14.3 ± 0.7 months were randomly assigned to one of two group pens: one group was fed high amounts of starch-rich concentrates (HCG; = 10), the other was fed a fibre-based diet (HFG; = 9). Behavioural activities performed by each horse were video-recorded over a 96-h period...
Is the Use of Bisphosphonates Putting Horses at Risk? An Osteoclast Perspective.
Animals : an open access journal from MDPI    July 3, 2022   Volume 12, Issue 13 doi: 10.3390/ani12131722
Vergara-Hernandez FB, Nielsen BD, Colbath AC.Osteoclasts are unique and vital bone cells involved in bone turnover. These cells are active throughout the individual's life and play an intricate role in growth and remodeling. However, extra-label bisphosphonate use may impair osteoclast function, which could result in skeletal microdamage and impaired healing without commonly associated pain, affecting bone remodeling, fracture healing, and growth. These effects could be heightened when administered to growing and exercising animals. Bisphosphonates (BPs) are unevenly distributed in the skeleton; blood supply and bone turnover rate determ...
Influence of Short and Medium Distance Road Transport on the Acute Phase Proteins in Horses.
Journal of equine veterinary science    July 3, 2022   Volume 117 104061 doi: 10.1016/j.jevs.2022.104061
Carvalho Filho WP, Souto PC, Orozco AMO, Jiménez AKA, Girardi FM, Bento LD, Fonseca LAD.Horse transport is a common practice and is usually associated as a cause of stress in animals, with consequences for their well-being. There are several of evidence that stress can increase an acute phase response. The aim of this study was to verify whether the road transport of horses over distances of 50 and 300 kilometers induces changes in the values of acute phase proteins. To do this, the serum SDS-PAGE was performed and the bands obtained were identified by mass spectrometry (MALDI-TOF). The blood samples were collected in tubes without anticoagulant to obtain the serum, and the evalu...
Inbreeding depression and the probability of racing in the Thoroughbred horse.
Proceedings. Biological sciences    June 29, 2022   Volume 289, Issue 1977 20220487 doi: 10.1098/rspb.2022.0487
Hill EW, Stoffel MA, McGivney BA, MacHugh DE, Pemberton JM.Small effective population sizes and active inbreeding can lead to inbreeding depression due to deleterious recessive mutations exposed in the homozygous state. The Thoroughbred racehorse has low levels of population genetic diversity, but the effects of genomic inbreeding in the population are unknown. Here, we quantified inbreeding based on runs of homozygosity (ROH) using 297 K SNP genotypes from 6128 horses born in Europe and Australia, of which 13.2% were unraced. We show that a 10% increase in inbreeding () is associated with a 7% lower probability of ever racing. Moreover, a ROH-based g...
Severe Skin Lesions Caused by Persistent Bites of the Stable Fly Stomoxys calcitrans (Diptera: Muscidae) in a Donkey Sanctuary of Western Spain.
Journal of equine veterinary science    June 23, 2022   Volume 116 104056 doi: 10.1016/j.jevs.2022.104056
González MA, Bravo-Barriga D, Fernández EB, Frontera E, Ruiz-Arrondo I.Animal sanctuaries are important organisations that promote animal welfare and health as well as social awareness. Following the appearance of several donkeys with severe and distinctive skin lesions in a sanctuary from western Spain in 2021, a multicomponent study was performed to rule out the possible causes. The lesions were mainly concentrated on the extremities and, to a lesser extent, on the face and/or chest. The use of cotton leggings on their extremities as an external barrier to prevent them from bites and treatments with antiparasitic, antiseptic washes and dermatitis lotion showed ...
Tracking the Impact of Weather on Equine Activity While Pastured.
Journal of equine veterinary science    June 22, 2022   Volume 116 104052 doi: 10.1016/j.jevs.2022.104052
Keller GA, Nielsen BD, Vergara-Hernandez FB, Robison CI.Keeping horses outdoors on pasture full-time with free access to shelter holds numerous advantages over housing in stalls, promoting both better mental and physical health. One reason for these benefits is the potential for increased physical activity in horses outdoors on pasture versus those confined to stalls. However, it is not guaranteed the horse will take advantage of this opportunity for greater movement. For this reason, it is important to understand the various reasons why horse activity patterns change. The objective of this study was to investigate how various weather factors - inc...
Scoping review of end-of-life decision-making models used in dogs, cats and equids.
The Veterinary record    June 15, 2022   Volume 191, Issue 4 e1730 doi: 10.1002/vetr.1730
Cameron A, Pollock K, Wilson E, Burford J, England G, Freeman S.End-of-life decisions for companion animals can be stressful for veterinarians and owners, and when delayed result in poor animal welfare. Delayed euthanasia has been identified as a particularly prominent issue for horses. This scoping review aimed to identify the available literature on veterinary decision-making models, which can support end-of-life planning. A protocol was preregistered, and a structured literature search was performed on six electronic databases. Publications were reviewed against specifically developed eligibility criteria. Data from original studies and narrative-type r...
Survey of the knowledge and perceptions of horse owners in Ireland of common clinical conditions and their impact.
Equine veterinary journal    June 15, 2022   Volume 55, Issue 2 270-281 doi: 10.1111/evj.13589
Golding E, Neavyn Neita A, Walshe N, Hanlon A, Mulcahy G, Duggan V.As the primary decision-maker for their horse's health and welfare, owners' knowledge of clinical conditions may impact their horse's health. Anecdotal evidence suggests that the emotional impact of equine illness on the owner can be severe but research is lacking. Objective: To evaluate horse owners' self-declared knowledge of eight common equine health conditions and perceptions of the quality of information available; to ascertain respondents' perceptions of the severity of impact on their horse of the conditions and potential emotional impact on themselves and to establish the factors of g...
Behavioural responses of Konik Polski horses to natural, familiar sound of thunderstorm, and unfamiliar similar-sounding sounds of volcanic eruption and sea storms.
BMC veterinary research    May 30, 2022   Volume 18, Issue 1 207 doi: 10.1186/s12917-022-03314-4
WiÅ›niewska A, Janczarek I, Ryżak M, Tkaczyk E, KÄ™dzierski W.It is not clear, if modern Konik Polski horses have retained the ability to identify sounds in terms of danger. The aim of the study was to identify differences in their behaviour in response to the reproduction of volcanic eruption and sea storm sounds, assumed to be unfamiliar to these horses, as compared to their response to a thunderclap sound, considered by the horses as potentially dangerous. The study included 13 adult mares of the Konik Polski breed, kept under a free-range system. Their behavioural responses to the reproduction of the three natural sounds with an intensity of over 50â...
‘First Case of Stiff-Horse Syndrome in United Kingdom’.
Journal of equine veterinary science    May 29, 2022   Volume 116 104022 doi: 10.1016/j.jevs.2022.104022
Cantatore F, Marcatili M, Withers J.Stiff-person syndrome is a well-recognised disease in humans, whilst cases of stiff-horse syndrome (SHS) have been rarely reported in the veterinary medicine literature. SHS is a progressive immunomediated disorder of the central nervous system leading to a disturbance of gamma amino butyric acid transmission at the neuromuscular junction in which antibodies are produced against the enzyme glutamic acid decarboxylase. A 6 year-old Irish Sport Horse was presented for investigation of involuntary violent contraction of hindlimb and back muscles triggered by stress. The diagnosis of SHS was made ...
Comparison of the Current Situation of Equine Headshaking Syndrome in France and Switzerland Based on an Online Survey.
Animals : an open access journal from MDPI    May 28, 2022   Volume 12, Issue 11 1393 doi: 10.3390/ani12111393
Stange LM, Krieter J, Czycholl I.Equine headshaking syndrome (EHS) is characterised as non-physical and involuntary movement of the horse's head and neck. Although EHS is clinically simple to diagnose, its aetiopathogenesis often remains unclear. The aim of this study was to gain an overview of signalment and therapy possibilities used in France and Switzerland. To do this, an online survey was developed and distributed via newsletters. A total of 933 complete, answered surveys from France ( = 804) and Switzerland ( = 129) were evaluated. The median age in France was 12.4 years (CH = 14.3). Mostly geldings were affected (58.5...
Welfare Concerns for Mounted Load Carrying by Working Donkeys in Pakistan.
Frontiers in veterinary science    May 27, 2022   Volume 9 886020 doi: 10.3389/fvets.2022.886020
Bukhari SSUH, Rosanowski SM, McElligott AG, Parkes RSV.Working donkeys () are vital to people's livelihoods. They are essential for carrying goods, however, globally, overloading is one of the primary welfare concerns for working donkeys. We studied mounted load carrying by donkeys and associated factors in Pakistan. A cross-sectional study of donkey owners ( = 332) was conducted, and interviews were undertaken based on a questionnaire. Owners estimated that the median weight of their donkeys was 110 kg [interquartile range (IQR) 100-120 kg], and that they carried a median mounted load of 81.5 kg (IQR 63-99 kg). We found that 87.4% of donkeys carr...
Is Continuous Monitoring of Skin Surface Temperature a Reliable Proxy to Assess the Thermoregulatory Response in Endurance Horses During Field Exercise?
Frontiers in veterinary science    May 27, 2022   Volume 9 894146 doi: 10.3389/fvets.2022.894146
Verdegaal EJMM, Howarth GS, McWhorter TJ, Delesalle CJG.Hyperthermia is a performance and welfare issue for exercising horses. The thermoregulatory stressors associated with exercise have typically been estimated by responses in the laboratory. However, monitoring surface skin temperature (T ) coincident with core temperature (T ) has not previously been investigated in horses exercising in the field. We investigated the suitability of monitoring surface T as a metric of the thermoregulatory response, and simultaneously investigated its relationship with T using gastrointestinal (GI) temperature. We evaluated T in 13 endurance horses competing...
The Impact of Noise Anxiety on Behavior and Welfare of Horses from UK and US Owner’s Perspective.
Animals : an open access journal from MDPI    May 21, 2022   Volume 12, Issue 10 1319 doi: 10.3390/ani12101319
Riva MG, Dai F, Huhtinen M, Minero M, Barbieri S, Dalla Costa E.Noise anxiety is an over-reaction to loud noises commonly detected among pets and can greatly impact on their welfare and on their management. When exposed to noisy events, horses can show intense escape attempts, which may cause severe accidents for the horse and the rider/handler. The aim of the present study was to investigate, through a web survey, UK and US owners' perception of noise anxiety severity in their horses, their management strategies and perceived efficacy. The questionnaire was shared via social networking and advertised as "What is your horse afraid of?". Over a total of 183...
Oral Dimensions Related to Bit Size in Adult Horses and Ponies.
Frontiers in veterinary science    May 12, 2022   Volume 9 879048 doi: 10.3389/fvets.2022.879048
Anttila M, Raekallio M, Valros A.A bit that fits is essential for horse welfare and good communication with the ridden, driven or led horses. The bit causes pressure on the sensitive structures of the horse mouth. The aim of this study was to investigate variation in oral dimensions related to bit fit in adult horses and ponies and to evaluate bit fit by comparing oral dimensions with the currently used bit size selected by the horse owner. The study population consisted of 554 horses and ponies, 308 geldings and 246 mares, age 5-29 years, presented for routine dental care. Oral dimensions: mouth width, distance between upper...
Owner reported clinical signs and -treatment decisions in equine pastern dermatitis.
Schweizer Archiv fur Tierheilkunde    May 5, 2022   Volume 164, Issue 5 401-412 doi: 10.17236/sat00356
Oesch S, Kaiser-Thom S, Vidondo B, Gerber V.Equine pastern dermatitis has a high prevalence in the equine population, especially in draft breeds. This skin condition is difficult to treat, and it is suspected that owners often decide on a treatment without consulting a veterinarian. The objectives of this study were to describe owner-reported clinical signs, severity, and reasons to consult a veterinarian. Moreover, we inquired about preventive measures and treatments, both instituted by owners without previous consultation or prescribed by their veterinarians. A total of 123 horses (owners recruited over social media) were included in ...
Champing at the Bit for Improvements: A Review of Equine Welfare in Equestrian Sports in the United Kingdom.
Animals : an open access journal from MDPI    May 5, 2022   Volume 12, Issue 9 1186 doi: 10.3390/ani12091186
Holmes TQ, Brown AF.Equestrian sports, including racing (e.g., flat, steeple-chasing, harness or donkey derby); show-jumping; cross-country; dressage; polo; polocrosse; endurance; carriage driving; vaulting and hunting; are hugely popular in the UK, and they involve a significant number of people, both as participants and spectators, and tens of thousands of equids. In this paper, we discuss animal welfare as a complex and disputed issue, clarifying what the term means and how it can be measured. We review many aspects of welfare risk to equids used for sport, addressing issues encountered throughout their lives,...
Cross sectional epidemiological study of the severity of buccal ulceration and sharp enamel points in ridden and unridden horses.
Journal of applied animal welfare science : JAAWS    April 28, 2022   1-7 doi: 10.1080/10888705.2022.2070844
Mata F, Johnson C, Wilding L.The process of domestication of the horse introduced changes limiting accessibility to graze land and roughage while increasing highly digestible carbohydrates content of meal-fedrations. We have tested whether the effect of a higher degree of human contact impacts horses' welfare by assessing the development of sharp enamel points (SEP) and buccal ulcerations (BU) in ridden and unridden horses. We were able to fit logistic regression models significantly differentiating the impact of these two conditions in both groups of horses (p < 0.001 for SEP and p < 0.01 for BU). The impact is higher...
