  Title Effects on behaviour and rein tension on horses ridden with or without martingales and rein inserts Type Journal Article
  Year 2009 Publication The Veterinary Journal Abbreviated Journal  
  Volume 181 Issue 1 Pages 56-62  
  Keywords Horse behaviour; Horse welfare; Equitation science; Rein tension; Martingales  
  Abstract Unsteady hand position can cause discomfort to the horse, potentially leading to conflict behaviours (CB) such as head tossing or tail lashing. Some instructors feel that martingales or elastic rein inserts can reduce discomfort caused by inexperienced and unsteady hands. Others consider these devices to be inappropriate [`]crutches'. Four horses and nine riders were tested under three conditions in random order: plain reins, adjustable training martingales (TM), and elasticised rein inserts (RI). Rein-tension data (7 s) and behavioural data (30 s) were collected in each direction. Rein-tension data were collected via strain-gauge transducers. Behavioural data were assessed using an ethogram of defined behaviours. No differences in the number of CB were observed. Mean rein tension for TM was higher than that of RI or controls. Relative to the withers, the head was lower for horses ridden with martingales. Carefully fitted martingales may have a place in riding schools that teach novices.

  Title Injuries in the event horse: Training versus competition Type Journal Article
  Year 2008 Publication The Veterinary Journal Abbreviated Journal  
  Volume 175 Issue 1 Pages 76-81  
  Keywords Event horse; Superficial digital flexor tendonitis; Suspensory ligament desmitis; Exertional rhabdomyolysis  
  Abstract Two related studies on injuries sustained by event horses during competition and during training are reported. During the cross-country phase of competition, the most common injuries were lacerations and abrasions to the carpus and stifle. Superficial digital flexor tendonitis and exertional rhabdomyolysis were significantly more common during Cours Complete Internationale (CCI) competitions compared to one-day event (ODE) competitions. The difference in injury types at ODEs and CCI competitions probably relates to the increased athletic demands of the CCI and the closer veterinary observation at these competitions. The results of the training study indicate that 21% of horses intending to compete in a CCI did not start due to injury. Forty-three percent of these injuries involved soft tissue structures with injuries to the superficial digital flexor tendon and the suspensory ligament each accounting for 33%. The most important area for future research is investigation of the risk factors for these career-threatening soft tissue injuries.

  Title Horse injuries and racing practices in National Hunt racehorses in the UK: the results of a prospective cohort study Type Journal Article
  Year 2004 Publication The Veterinary Journal Abbreviated Journal  
  Volume 167 Issue 1 Pages 45-52  
  Keywords Racehorse; Horse; Injury; Cohort; National Hunt  
  Abstract A prospective cohort study was conducted on horses starting in hurdle and steeplechase races on six UK racecourses in 2000 and 2001. Trainers or carers were questioned on the horses' pre-race routine and observational data were collected in the stables and parade ring. Some practices were common to many starters, such as withholding food and water before racing whereas other practices, such as schooling frequency, were more variable. There was a total of 2879 starts and a total of 83 injuries or medical events (28.8/1000 starts). The commonest types of injury were tendon/suspensory injuries and lacerations/wounds. Multivariable logistic regression models were used to identify the relationship between predictor variables and the risk of injury. Risk of injury or medical event was associated with distance of the race and weight carried. The risk of injury, excluding medical events, was associated with the speed of the race and foot conformation.

  Title Social organization and dispersion of introduced kulans (Equus hemionus kulan) and Przewalski horses (Equus przewalski) in the Bukhara Reserve, Uzbekistan Type Journal Article
  Year 2001 Publication Journal of Arid Environments Abbreviated Journal J. Arid. Environ.  
  Volume 47 Issue 3 Pages 309-323  
  Keywords Przewalski horses; kulans; Central Asia; home range; behaviour  
  Abstract Asiatic wild asses and Przewalski horses initially inhabited steppe, semi-desert and desert areas, but Przewalski horses became extinct in the wild, and kulans disappeared at the beginning of the 20th century, except for a small population in Turkmenistan. The Bukhara Breeding Centre (Uzbekistan) was created in 1976 for reintroduction and conservation of wild ungulate species. In 1977-1978, five kulans (two males and three females), from Barsa-Kelmes island on the Aral sea, were introduced into the reserve. The group increased to 25-30 animals in 1989-1990, when eight Przewalski horses from Moscow and St Petersburg zoos were introduced. We analysed the home ranges, preferred habitats and social interactions of these closely related species during 1995-1998 by seasonal and group composition. Horses and asses formed a reproductive group and a secondary non-reproductive group. The home range of the secondary group was larger than the reproductive group and seemed to be less dependent from the watering places. Przewalski horses were less adapted to semi-desert conditions (both water and vegetation needs) than kulan.

  Title Changes in cortisol release and heart rate and heart rate variability during the initial training of 3-year-old sport horses Type Journal Article
  Year 2010 Publication Hormones and Behavior Abbreviated Journal Horm Behav  
  Volume 58 Issue 4 Pages 628-636  
  Keywords Horse; Initial training; Cortisol; Heart rate variability  
  Abstract Based on cortisol release, a variety of situations to which domestic horses are exposed have been classified as stressors but studies on the stress during equestrian training are limited. In the present study, Warmblood stallions (n = 9) and mares (n = 7) were followed through a 9 respective 12-week initial training program in order to determine potentially stressful training steps. Salivary cortisol concentrations, beat-to-beat (RR) interval and heart rate variability (HRV) were determined. The HRV variables standard deviation of the RR interval (SDRR), RMSSD (root mean square of successive RR differences) and the geometric means standard deviation 1 (SD1) and 2 (SD2) were calculated. Nearly each training unit was associated with an increase in salivary cortisol concentrations (p < 0.01). Cortisol release varied between training units and occasionally was more pronounced in mares than in stallions (p < 0.05). The RR interval decreased slightly in response to lunging before mounting of the rider. A pronounced decrease occurred when the rider was mounting, but before the horse showed physical activity (p < 0.001). The HRV variables SDRR, RMSSD and SD1 decreased in response to training and lowest values were reached during mounting of a rider (p < 0.001). Thereafter RR interval and HRV variables increased again. In contrast, SD2 increased with the beginning of lunging (p < 0.05) and no changes in response to mounting were detectable. In conclusion, initial training is a stressor for horses. The most pronounced reaction occurred in response to mounting by a rider, a situation resembling a potentially lethal threat under natural conditions.

  Title Cortisol release and heart rate variability in horses during road transport Type Journal Article
  Year 2010 Publication Hormones and Behavior Abbreviated Journal Horm. Behav.  
  Volume 57 Issue 2 Pages 209-215  
  Keywords Horse; Transport; Cortisol; Heart rate variability  
  Abstract Based on plasma cortisol concentrations it is widely accepted that transport is stressful to horses. So far, cortisol release during transport has not been evaluated in depth by non-invasive techniques such as analysis of salivary cortisol and faecal cortisol metabolites. Transport also causes changes in heart rate and heart rate variability (HRV). In this study, salivary cortisol, faecal cortisol metabolites, heart rate and HRV in horses transported by road for short (one and 3.5 h) and medium duration (8 h) were determined. With the onset of transport, salivary cortisol increased immediately but highest concentrations were measured towards the end of transport (4.1 ± 1.6, 4.5 ± 2.6, 6.5 ± 1.8 ng/ml in horses transported for one, 3.5 and 8 h, respectively). Faecal cortisol metabolite concentrations did not change during transport, but 1 day after transport for 3.5 and 8 h had increased significantly (p < 0.01), reflecting intestinal passage time. Compared to salivary cortisol, changes in faecal cortisol metabolites were less pronounced. Heart rate increased and beat-to-beat (RR) interval decreased (p < 0.05) with the onset of transport. Standard deviation of heart rate increased while root mean square of successive RR differences (RMSSD) decreased in horses transported for 3.5 (from 74 ± 5 to 45 ± 6 ms) and 8 h (from 89.7 ± 7 to 59 ± 7 ms), indicating a reduction in vagal tone. In conclusion, transport of horses over short and medium distances leads to increased cortisol release and changes in heart rate and HRV indicative of stress. The degree of these changes is related to the duration of transport. Salivary cortisol is a sensitive parameter to detect transient changes in cortisol release.

  Title The use of human-given cues by domestic horses, Equus caballus, during an object choice task Type Journal Article
  Year 2010 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 79 Issue 6 Pages 1205-1209  
  Keywords domestication; Equus caballus; horse; interspecific communication; marker cue; pointing; social cognition  
  Abstract Selection pressures during domestication are thought to lead to an enhanced ability to use human-given cues. Horses fulfil a wide variety of roles for humans and have been domesticated for at least 5000 years but their ability to read human cues has not been widely studied. We tested the ability of 28 horses to attend to human-given cues in an object choice task. We included five different cues: distal sustained pointing, momentary tapping, marker placement, body orientation and gaze (head) alternation. Horses were able to use the pointing and marker placement cues spontaneously but not the tapping, body orientation and gaze alternation cues. The overall pattern of responding suggests that horses may use cues that provide stimulus enhancement at the time of choice and do not have an understanding of the communicative nature of the cues given. As such, their proficiency at this task appears to be inferior to that of domestic dogs, Canis lupus familiaris, but similar to that of domestic goats, Caprus hircus.

  Title Maternal investment results in better foal condition through increased play behaviour in horses Type Journal Article
  Year 2008 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.  
  Volume 76 Issue 5 Pages 1511-1518  
  Keywords Equus caballus; feral horse; maternal investment; play  
  Abstract Play behaviour is widespread in mammals, but benefits to play have been difficult to demonstrate. Physical training is one of the many proposed hypotheses, suggesting that males and females should play differently, that increased maternal investment should lead to increases in play, and that increases in play should result in physical advantages. In a population of feral horses, Equus caballus, males and females did not differ in their play behaviour except that males initiated more of their play bouts than females. Maternal condition influenced play behaviour only in males, with sons of mothers in good condition playing more. However, when we controlled for maternal effects by comparing a son and a daughter of the same mother, daughters played more when their mother was in poor condition and sons played more when their mother was in good condition. Mothers of foals that played more lost more condition. Therefore, the difference in play behaviour could not be explained by offspring sex or maternal condition alone, but play behaviour mirrored variation in maternal investment. In addition, those individuals that played more survived better and had better body condition as yearlings despite weaning earlier. Since increased activity has been linked to enhanced musculoskeletal development in domestic horses, we suggest that play provides a link between increased maternal investment, increased body condition and future reproductive success in feral horses, and probably in other species.

  Title Behavioural adaptation in the domestic horse: potential role of apparently abnormal responses including stereotypic behaviour Type Journal Article
  Year 2005 Publication Livestock Production Science Abbreviated Journal Livest. Prod. Sci.  
  Volume 92 Issue 2 Pages 177-182  
  Keywords Behavioural adaptation; Horse; Stereotypic behaviour  
  Abstract Classically, biologists have considered adaptation of behavioural characteristics in terms of long-term functional benefits to the individual, such as survival or reproductive fitness. In captive species, including the domestic horse, this level of explanation is limited, as for the most part, horses are housed in conditions that differ markedly from those in which they evolved. In addition, an individual horse's reproductive fitness is largely determined by man rather than its own behavioural strategies. Perhaps for reasons of this kind, explanations of behavioural adaptation to environmental challenges by domestic animals, including the capacity to learn new responses to these challenges, tend to concentrate on the proximate causes of behaviour. However, understanding the original function of these adaptive responses can help us explain why animals perform apparently novel or functionless activities in certain housing conditions and may help us to appreciate what the animal welfare implications might be. This paper reviews the behavioural adaptation of the domestic horse to captivity and discusses how apparently abnormal behaviour may not only provide a useful practical indicator of specific environmental deficiencies but may also serve the animal as an adaptive response to these deficiencies in an “abnormal” environment.

  Title Changes in cortisol release and heart rate variability in sport horses during long-distance road transport Type Journal Article
  Year 2010 Publication Domestic Animal Endocrinology Abbreviated Journal Domest Anim Endocrinol  
  Volume 38 Issue 3 Pages 179-189  
  Keywords Horse; Transport; Cortisol; Heart rate variability  
  Abstract It is widely accepted that transport is stressful for horses, but only a few studies are available involving horses that are transported regularly and are accustomed to transport. We determined salivary cortisol immunoreactivity (IR), fecal cortisol metabolites, beat-to-beat (RR) interval, and heart rate variability (HRV) in transport-experienced horses (N = 7) in response to a 2-d outbound road transport over 1370 km and 2-d return transport 8 d later. Salivary cortisol IR was low until 60 min before transport but had increased (P < 0.05) 30 min before loading. Transport caused a further marked increase (P < 0.001), but the response tended to decrease with each day of transport. Concentrations of fecal cortisol metabolites increased on the second day of both outbound and return transports and reached a maximum the following day (P < 0.001). During the first 90 min on Day 1 of outbound transport, mean RR interval decreased (P < 0.001). Standard deviations of RR interval (SDRR) decreased transiently (P < 0.01). The root mean square of successive RR differences (RMSSD) decreased at the beginning of the outbound and return transports (P < 0.01), reflecting reduced parasympathetic tone. On the first day of both outbound and return transports, a transient rise in geometric HRV variable standard deviation 2 (SD2) occurred (P < 0.01), indicating increased sympathetic activity. In conclusion, transport of experienced horses leads to increased cortisol release and changes in heart rate and HRV, which is indicative of stress. The degree of these changes tended to be most pronounced on the first day of both outbound and return transport.
