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.
Human Injuries Associated with the Transport of Horses by Road.
Animals : an open access journal from MDPI    May 10, 2023   Volume 13, Issue 10 1594 doi: 10.3390/ani13101594
Riley CB, Padalino B, Rogers CW, Thompson KR.There is an increased understanding of shared human-animal risk in terms of "one welfare", whereby when animals are at risk, so are people, so preventing injury to one species may also prevent injury to the other. Because transport-related injuries to horses are common, the authors considered this paradigm to study road equine transport-related injuries to humans in New Zealand. The aim was to determine their frequency and associated factors by distributing a survey to horse industry participants through industry organisations asking about their horse activities, road transport experiences, an...
Understanding and treating equine behavioural problems.
Veterinary journal (London, England : 1997)    April 29, 2023   Volume 296-297 105985 doi: 10.1016/j.tvjl.2023.105985
Carroll SL, Sykes BW, Mills PC.Behaviour-related issues are common in horses. Many 'undesirable behaviours' pose important safety concerns for the human handlers / riders / carers, as well as welfare concerns for the horse. Undesirable behaviours can also devalue a horse, or result in the horse being re-homed, relinquished, or euthanased. Undesirable behaviours occur for a range of reasons. These include physiological causes, poor management, and the use of inappropriate or poorly applied handling and training techniques. The potential contribution of each of these aspects must be considered when attempting to reduce or eli...
Updates on Diagnosis and Management of Colic in the Field and Criteria for Referral.
The Veterinary clinics of North America. Equine practice    April 28, 2023   Volume 39, Issue 2 175-195 doi: 10.1016/j.cveq.2023.03.001
Bookbinder L, Prisk A.Gastrointestinal colic is the most common primary care equine emergency and affects nearly one of four horses per year. Colic is a significant welfare concern for equine patients and a financial and emotional burden for owners. The primary care practitioner is instrumental in identifying critical cases quickly and making appropriate management recommendations to improve patient outcomes.
Mental Experiences in Wild Animals: Scientifically Validating Measurable Welfare Indicators in Free-Roaming Horses.
Animals : an open access journal from MDPI    April 28, 2023   Volume 13, Issue 9 1507 doi: 10.3390/ani13091507
Harvey AM, Beausoleil NJ, Ramp D, Mellor DJ.The mental experiences of animals are what characterises their welfare status. The Five Domains Model for assessing welfare aligns with the understanding that physical and mental states are linked. Following measurement of indicators within each of the four physical/functional Domains (1. Nutrition; 2. Physical environment; 3. Health; and 4. Behavioural interactions), the anticipated negative or positive affective consequences (mental experiences) are cautiously inferred and assigned to Domain 5. Those inferences derive credibility from validated knowledge of the underlying systems of physiolo...
Changes in Management Lead to Improvement and Healing of Equine Squamous Gastric Disease.
Animals : an open access journal from MDPI    April 28, 2023   Volume 13, Issue 9 1498 doi: 10.3390/ani13091498
Kranenburg LC, van der Poel SH, Warmelink TS, van Doorn DA, van den Boom R.Equine squamous gastric disease (ESGD) is common in horses and poses a serious welfare problem. Several risk factors have been identified and ESGD is routinely treated with omeprazole. Fourteen mares, previously used as embryo recipients and diagnosed with ESGD, were selected. Horses were confined to individual stalls, exercised once daily, and fed ad libitum hay, 1 kg of a low starch compound complementary feed and a mineral supplement. Half of the horses received a compound containing hydrolysed collagen (supplement) and the other half did not (control). At the start of the study, ESGD score...
Equine Social Behaviour: Love, War and Tolerance.
Animals : an open access journal from MDPI    April 26, 2023   Volume 13, Issue 9 1473 doi: 10.3390/ani13091473
Torres Borda L, Auer U, Jenner F.Sociality is an ethological need of horses that remained unchanged by domestication. Accordingly, it is essential to include horses' social behavioural requirements and the opportunity to establish stable affiliative bonds in equine management systems and welfare assessment. Thus, this systematic review aims to provide an up-to-date analysis of equine intraspecific social ethograms. A literature review yielded 27 papers that met the inclusion criteria by studying adult (≥2 years) equine social behaviour with conspecifics using a well-defined ethogram. Social interactions were observed in 851...
GLAD Scale for Ranking Welfare of Horses on Arrival after Transport to Slaughterhouses.
Animals : an open access journal from MDPI    April 25, 2023   Volume 13, Issue 9 1465 doi: 10.3390/ani13091465
Padalino B, Benedetti B, Felici M, Bicout DJ.To date, there is no official method for measuring horse welfare after transport. This study aimed to develop a scale to classify horses into four categories: good shape; light affected; affected; down (GLAD) based on their welfare impairment measured at unloading. To this end, 15 animal-based measures (ABMs), previously recorded from 1019 horses, were scored. Weight and severity scores provided by welfare experts, alongside the number of welfare principles highlighted by the ABM, were assigned to each ABM. The welfare impairment () of each horse was then calculated as the weighted sum of the ...
Social Box: A New Housing System Increases Social Interactions among Stallions.
Animals : an open access journal from MDPI    April 20, 2023   Volume 13, Issue 8 1408 doi: 10.3390/ani13081408
Zollinger A, Wyss C, Bardou D, Bachmann I.In domestic conditions, adult stallions are mostly housed individually in internal stables to reduce the risk of injuries during social interactions. Social deprivation in horses results in physiological stress and behavioural problems. The aim of this study was to test the "social box" (SB), which allows closer physical contact between neighbouring horses. Eight pairs of stallions (n = 16) were filmed over a 24 h period in the SB and in their usual box stables, "conventional boxes" (CB), which strongly restrict tactile contact. The effect of housing in the SB on behaviour and the occurrence a...
The effects of obesity and insulin dysregulation on mare reproduction, pregnancy, and foal health: a review.
Frontiers in veterinary science    April 20, 2023   Volume 10 1180622 doi: 10.3389/fvets.2023.1180622
Hallman I, Karikoski N, Kareskoski M.Obesity is a growing welfare concern in modern equine populations and predisposes horses to disturbances in energy metabolism such as insulin dysregulation. However, equine metabolic syndrome has only been recognized in recent decades. Functioning energy metabolism is pivotal to normal body homeostasis and affects essentially all organ systems, including reproduction. Previous literature suggests that obesity has an effect not only on the reproductive processes in mares but also on offspring health, predisposing the offspring to later-onset orthopedic and metabolic problems. This review focuse...
Evaluation of thermoregulation of horses (Equus caballus) submitted to two methods of post-exercise cooling, in hot and humid climate conditions, in the Eastern Amazon.
Frontiers in veterinary science    April 17, 2023   Volume 10 1150763 doi: 10.3389/fvets.2023.1150763
Lisboa BRF, da Silva JAR, da Silva WC, Barbosa AVC, Silva LKX, Lourenço-Júnior JB.In Brazil, the study on equine thermoregulation has not shown considerable advances, moreover, in the Amazon, this is a little explored aspect. This study aims to evaluate the thermoregulation of horses submitted to two methods of post-exercise cooling, in the climatic conditions of the Eastern Amazon. The experiment was conducted at Centro Hipico, Ananindeua, Para, for 15 days. Ten male horses, castrated of the Brazilian breed, aged 13 years and with an average weight of 482.3 kg were used. Equestrianism, which was exercised with pre-established protocol in the arena and track, for 30 min. Af...
Heat stress in horses: a literature review.
International journal of biometeorology    April 15, 2023   Volume 67, Issue 6 957-973 doi: 10.1007/s00484-023-02467-7
Kang H, Zsoldos RR, Sole-Guitart A, Narayan E, Cawdell-Smith AJ, Gaughan JB.Healthy adult horses can balance accumulation and dissipation of body heat to maintain their body temperature between 37.5 and 38.5 °C, when they are in their thermoneutral zone (5 to 25 °C). However, under some circumstances, such as following strenuous exercise under hot, or hot and humid conditions, the accumulation of body heat exceeds dissipation and horses can suffer from heat stress. Prolonged or severe heat stress can lead to anhidrosis, heat stroke, or brain damage in the horse. To ameliorate the negative effects of high heat load in the body, early detection of heat stress and im...
Factors Affecting Thoroughbred Online Auction Prices in Non/Post-Racing Careers.
Animals : an open access journal from MDPI    April 13, 2023   Volume 13, Issue 8 doi: 10.3390/ani13081329
Camp M, Kibler ML, Ivey JLZ, Thompson JM.Racehorse welfare is a prominent, public issue which affects nearly every aspect of the racing industry. Thoroughbred care after race career completion has garnered increasing attention from the equine industry, general public, and animal welfare groups alike. As the average racehorse's career lasts just 4.5 years, owner demand for thoroughbreds is essential for post-race careers and acceptable welfare standards. This study utilized data from and hedonic pricing models to analyze buyer demand for thoroughbreds sold in online auctions held from 2012 to 2020. The results indicate buyer preferenc...
Analysis of Various Facial Expressions of Horses as a Welfare Indicator Using Deep Learning.
Veterinary sciences    April 10, 2023   Volume 10, Issue 4 283 doi: 10.3390/vetsci10040283
Kim SM, Cho GJ.This study aimed to prove that deep learning can be effectively used for identifying various equine facial expressions as welfare indicators. In this study, a total of 749 horses (healthy: 586 and experiencing pain: 163) were investigated. Moreover, a model for recognizing facial expressions based on images and their classification into four categories, i.e., resting horses (RH), horses with pain (HP), horses immediately after exercise (HE), and horseshoeing horses (HH), was developed. The normalization of equine facial posture revealed that the profile (99.45%) had higher accuracy than the fr...
The Effect of Insect Bite Hypersensitivity on Movement Activity and Behaviour of the Horse.
Animals : an open access journal from MDPI    April 8, 2023   Volume 13, Issue 8 1283 doi: 10.3390/ani13081283
Söderroos D, Ignell R, Haubro Andersen P, Bergvall K, Riihimäki M.Insect bite hypersensitivity (IBH) associated with biting midges is a common allergic skin disease in horses, reducing the welfare of affected horses. This study investigated the effect of IBH on animal welfare and behaviour and assessed a new prophylactic insect repellent. In total, 30 horses were recruited for a prospective cross-over and case-control study. Clinical signs of IBH, inflammatory markers in skin biopsies and behavioural data (direct observations, motion index) were scored longitudinally during two consecutive summers. No differences were observed in the total number of itching...
Rate of obesity within a mixed-breed group of horses in Ireland and their owners’ perceptions of body condition and useability of an equine body condition scoring scale.
Irish veterinary journal    April 6, 2023   Volume 76, Issue 1 9 doi: 10.1186/s13620-023-00237-w
Golding E, Al Ansari ASA, Sutton GA, Walshe N, Duggan V.Equine obesity is a significant health and welfare concern. The proportion of domestic horse populations that are overweight are as high as 45%. As the primary decision-makers for their horses' care, owners are theoretically ideally placed to identify whether their horses are appropriately conditioned, however, research in other countries has shown that many owners are unable to accurately judge their horse's body condition. In this study, through the comparison of body condition scoring (BCS) performed by an expert and the horse owners and interviews with owners, we aimed to identify the prop...
Integrative genomics analysis highlights functionally relevant genes for equine behaviour.
Animal genetics    March 27, 2023   Volume 54, Issue 4 457-469 doi: 10.1111/age.13320
Holtby AR, Hall TJ, McGivney BA, Han H, Murphy KJ, MacHugh DE, Katz LM, Hill EW.Behavioural plasticity enables horses entering an exercise training programme to adapt with reduced stress. We characterised SNPs associated with behaviour in yearling Thoroughbred horses using genomics analyses for two phenotypes: (1) handler-assessed coping with early training events [coping] (n = 96); and (2) variation in salivary cortisol concentration at the first backing event [cortisol] (n = 34). Using RNA-seq derived gene expression data for amygdala and hippocampus tissues from n = 2 Thoroughbred stallions, we refined the SNPs to those with functional relevance to behaviour by c...
The Social and Reproductive Challenges Faced by Free-Roaming Horse (Equus caballus) Stallions.
Animals : an open access journal from MDPI    March 24, 2023   Volume 13, Issue 7 1151 doi: 10.3390/ani13071151
Górecka-Bruzda A, Jaworska J, Stanley CR.In captivity, intact male horses, due to their sexual drive, are usually socially isolated from other horses. This lifestyle strongly contrasts with that experienced by horses living in free-roaming, feral, or semi-feral conditions, where adult stallions have several roles in their social group, with successful reproduction being their primary drive. Reproductive skew in wild populations is high; many stallions will fail to reproduce at all, while others achieve high levels of reproductive success, siring a large number of foals. Successful stallions are those with particular characteristics a...
Evaluation of Substance P as a New Stress Parameter in Horses in a Stress Model Involving Four Different Stress Levels.
Animals : an open access journal from MDPI    March 24, 2023   Volume 13, Issue 7 doi: 10.3390/ani13071142
Scholler D, Zablotski Y, May A.Stress has a significant impact on equine welfare. There are some studies on the stress response in horses ridden with tight nosebands, but little is known about other stress parameters than cortisol, which potentially could address an emotional component. In this study, blood samples of a total of 74 warmblood horses were used to establish reference values for plasma substance P (SP) concentrations. Moreover, 16 of these warmblood horses were included in a stress model. Four different stress levels (level 1: horses ridden with loose noseband, level 2: tight noseband, level 3: loose noseband a...
The impact of strategic ventilation adjustments on stress responses in horses housed full-time in a vector-protected barn during the African horse sickness outbreak in Thailand.
Animal welfare (South Mimms, England)    March 23, 2023   Volume 32 e19 doi: 10.1017/awf.2023.10
Poochipakorn C, Joongpan W, Tongsangiam P, Phooseerit A, Leelahapongsathon K, Chanda M.The severe outbreak of African horse sickness (AHS) in Thailand has forced horses to reside full-time inside barns that are covered by a small mesh net to prevent minuscule AHS insect vectors from gaining access. However, housing in the net-covered barn induces stress in horses, which compromises their welfare. Implementing strategic airflow adjustment while retaining the vector-protection characteristics has been proposed to help alleviate this problem. The present study aimed to investigate the effect of strategic ventilation adjustment on blood cortisol levels, heart rate and behaviour in h...

The Effect of Stabling Routines on Potential Behavioural Indicators of Affective State in Horses and Their Use in Assessing Quality of Life.
Animals : an open access journal from MDPI    March 15, 2023   Volume 13, Issue 6 1065 doi: 10.3390/ani13061065
Bradshaw-Wiley E, Randle H.Increasing interest in equine welfare has emphasised the need for objective and reliable behavioural indicators of horses' affective state. However, research has yielded mixed results regarding behaviours suited for industry use largely because they are subject to anthropomorphic interpretation. Stabling is commonly used to manage domesticated horses despite research indicating that it can negatively impact horse welfare, but its effect on their affective state is yet to be quantified. Ten adult horses (11.8 ± 4.4 years) were observed either on a day- (DS) or night-stabling (NS) schedule over...
Risk factors for, and prediction of, exertional heat illness in Thoroughbred racehorses at British racecourses.
Scientific reports    March 14, 2023   Volume 13, Issue 1 3063 doi: 10.1038/s41598-023-27892-x
Trigg LE, Lyons S, Mullan S.The development of exertional heat illness (EHI) is a health, welfare and performance concern for racehorses. However, there has been limited multivariable assessment of the possible risk factors for EHI in racehorses, despite such information being vital for regulators to effectively manage the condition. Consequently, this study aimed to identify the risk factors associated with the occurrence of EHI in Thoroughbred racehorses and assess the ability of the risk factor model to predict the occurrence of EHI in racehorses to assist in early identification. Runners at British racecourses record...
Comparison of Asymmetry During Trot In-Hand With Evaluations of Discomfort and Pain in Horses While Exercised.
Journal of equine veterinary science    March 11, 2023   Volume 126 104282 doi: 10.1016/j.jevs.2023.104282
Soiluva J, Häyrinen L, Gangini G, Öistämö R, Gracia-Calvo LA, Raekallio MR.Traditional visual lameness assessment is subjective. Ethograms have been developed for evaluating pain and objective sensors to detect lameness. Heart rate (HR) and heart rate variability (HRV) have been used to evaluate stress and pain. The aim of our study was to compare subjective and behavioral lameness scores, a sensor system measuring movement asymmetry, HR, and HRV. We hypothesized that these measures would show related trends. In 30 horses, an inertial sensor system was used to measure movement asymmetries during trot in-hand. A horse was categorized as sound if each asymmetry was les...
Social License to Operate-Why Public Perception Matters for Horse Sport-Some Personal Reflections.
Journal of equine veterinary science    March 8, 2023   Volume 124 104266 doi: 10.1016/j.jevs.2023.104266
Heleski CR.What is a social license to operate (SLO)? Why would this concept matter for horse sport? In perhaps its simplest form, "social license to operate" is the public's perception of an industry or activity. It is a challenging concept to fully grasp because it does not arrive as a document given by a government agency. Yet it is every bit as important-perhaps more so. Does the industry in question operate with transparency? Does the public believe in the integrity of the stakeholders who are most likely to benefit from the activity? Do people believe there is legitimacy in the scrutinized industry...
Changes in eating time, chewing activity and dust concentration in horses fed either alfalfa cubes or long-stem hay.
Veterinary medicine and science    March 6, 2023   Volume 9, Issue 3 1154-1162 doi: 10.1002/vms3.1102
Petz V, Khiaosa-Ard R, Iben C, Zebeli Q.Chewing is an essential physiological process in horses; yet, the physical form of feeds may affect their chewing and feeding behaviour with consequences for equine digestion and health. The present study evaluated the potential of a commercial forage cubes made from alfalfa and mixed meadow grasses to maintain chewing activity when compared with a traditional long and fibre-rich hay. An additional aim was to measure the dust formation during feeding. The experiment was a crossover design with six horses (11 ± 4 years old, mean ± SD), fed with 5 kg (as-fed basis) of their feed (long hay...
Electrocardiographic and Echocardiographic Parameters in Pega Breed Donkeys: A Descriptive Study.
Animals : an open access journal from MDPI    February 27, 2023   Volume 13, Issue 5 861 doi: 10.3390/ani13050861
Cruz-Aleixo AS, de Oliveira KC, de Oliveira Ferreira LV, Cedeo Quevedo DA, Cruz RKS, Tsunemi MH, Chiacchio SB, Lourenço MLG.Clinical, electrocardiographic and echocardiographic parameters in Pega donkeys are scarce in the literature; hence, this study was performed to describe the echocardiographic and electrocardiographic measurements in Pega breed donkeys. The objectives of this study were to describe and illustrate the clinical, electrocardiographic, and echocardiographic parameters in Pega donkeys used for reproduction. Fifty Pega breed donkeys were evaluated, with an average age of 3.4 years and with 20 males and 30 females. In each animal, the electrocardiographic examination at rest was performed using the T...
Does housing system affect horse welfare? The AWIN welfare assessment protocol applied to horses kept in an outdoor group-housing system: The ‘parcours’.
Animal welfare (South Mimms, England)    February 27, 2023   Volume 32 e22 doi: 10.1017/awf.2023.9
Dai F, Dalla Costa E, Minero M, Briant C.Outdoor group housing is generally reported as being beneficial to the welfare of horses compared to single boxes, being considered to show greater similarities with the living conditions of feral horses, allowing full expression of behaviours such as grazing, social interactions and free movement. However, concerns persist regarding the ability to maintain a good nutritional state and the possibility of acquiring injury. No data reporting a comprehensive assessment of welfare for horses in outdoor group-housing systems are currently available. The present study aimed at applying a scientifica...
Welfare of extensively managed Swedish Gotland ponies.
Animal welfare (South Mimms, England)    February 23, 2023   Volume 32 e21 doi: 10.1017/awf.2023.20
Viksten SM, Hartmann E, Schneller K, Steen M.It has been suggested that grazing horses could be used as a credible tool for landscape conservation which would, at the same time, improve horse welfare as opposed to conventional housing. A study was conducted between May 2014 and April 2015 on 12 one year old Gotland ponies managed extensively without supplementary feed. Monthly animal welfare assessments (n = 13) revealed welfare issues in most of the horses, i.e. low body condition score (BCS < 3/5), recurring poor skin condition in 11/12 horses and ocular discharge in 7/12 horses. At the end of the study, compared to the beginning, ch...
Changing Hearts and Minds in the Equestrian World One Behaviour at a Time.
Animals : an open access journal from MDPI    February 19, 2023   Volume 13, Issue 4 748 doi: 10.3390/ani13040748
Wolframm IA, Douglas J, Pearson G.Equestrianism is currently facing a range of pressing challenges. These challenges, which are largely based on evolving attitudes to ethics and equine wellbeing, have consequences for the sport's social licence to operate. The factors that may have contributed to the current situation include overarching societal trends, specific aspects of the equestrian sector, and factors rooted in human nature. If equestrianism is to flourish, it is evident that much needs to change, not the least, human behaviour. To this end, using established behaviour change frameworks that have been scientifically val...
How to Understand Them? A Review of Emotional Indicators in Horses.
Journal of equine veterinary science    February 16, 2023   Volume 126 104249 doi: 10.1016/j.jevs.2023.104249
Maurício LS, Leme DP, Hötzel MJ.Stabled horses often experience negative emotions due to the inappropriate living conditions imposed by humans. However, identifying what emotions horses experience and what can trigger positive and negative emotions in stabled horses can be challenging. In this article we present a brief history of the study of emotions and models that explain emotions from a scientific point of view and the physiological bases and functions of emotions. We then review and discuss physiological and behavioral indicators and cognitive bias tests developed to assess emotions in horses. Hormone concentrations, b...
