The Reported Use of Tongue-Ties and Nosebands in Thoroughbred and Standardbred Horse Racing-A Pilot Study.

ABSTRACT: This article reports on the results of a survey of racehorse trainers (n = 112) outlining the reasons for tongue-tie (TT) and noseband (NB) use by Thoroughbred trainers (TBTs) (n = 72) and Standardbred trainers (SBTs) (n = 40). The study also investigated the reported effectiveness of TTs and possible complications arising from their use. Tongue-tie use was reported by 62.5% (n = 70) of racehorse trainers. The reasons for TT use varied between TBTs and SBTs. For TBTs, the most common reason for TT use was to prevent or reduce airway obstruction (72.3%, n = 34), followed closely by to prevent or reduce airway noise (55.3%, n = 16). Standardbred trainers assigned equal importance for TT use [to prevent or reduce airway obstruction (69.6%, n = 16) and to prevent the horse from moving its tongue over the bit (69.6%, n = 16)]. Tongue-ties were considered significantly less effective at improving performance than at reducing airway obstruction and preventing the tongue from moving over the bit (t = -2.700, p = 0.0007). For respondents who used both TTs and NBs, there was a mild to moderate positive association between the reasons for using TTs and NBs. Of the 70 TT-using respondents, 51.4% (n = 36) recorded having encountered either a physical or behavioural complication due to TT use, with redness/bruising of the tongue (20.0%, n = 14) being the most common physical complication reported. Duration of use influenced the risk of observing complications. The likelihood of a respondent reporting a behavioural complication due to TT use increased with every minute of reported application and a nine-minute increment in application period doubled the odds of a respondent reporting a complication. Tightness was a risk factor for physical complications: Checking TT tightness by noting the tongue as not moving was associated with increased reporting of physical complications (OR = 6.59; CI 1.1-67.5). This pilot study provides some insight into how and why TTs are applied by some racehorse trainers, and the potential risks associated with their use. A further study of a larger cohort is recommended because these results are valid for only the 112 trainers who responded and cannot be generalized to the equine industry.

Project description:Reasons for performing studyPalmar/plantar osteochondral disease (POD) is a common, debilitating condition in Thoroughbred racehorses; however, training- and racing-related factors associated with this disease are unknown.ObjectivesTo determine horse-, racing- and training-related risk factors for POD. The general hypotheses were that early training and racing, and increased intensity of racing and training, lead to increased severity of POD.MethodsThe metacarpo/metatarsophalangeal joints of 164 Thoroughbred racehorses were examined at post mortem and graded for third metacarpal and metatarsal POD. The relationships between training- and racing-related factors and grade of POD in each condyle were determined using multilevel, multivariable, ordinal logistic regression models.ResultsA total of 1288 condyles were graded. Factors associated with higher grades of POD were the total lifetime number of races, an increase in gallop sessions in the previous season, racing before import to Hong Kong and an increase in the number of short (8-16 weeks) between-race intervals per season. Horses in their first racing season were more likely to have lower POD grades, while horses that had a long between-race interval (greater than 16 weeks) in the season prior to euthanasia were also more likely to have lower POD grades. Lower POD grades were significantly more likely as days since last race increased up to 400 days. Age at first race was not significantly associated with grade of POD.Conclusions and potential relevanceCumulative racing exposure and training intensity in the previous season were associated with higher grades of POD, supporting the hypothesis that the disease is due to repetitive loading. Longer between-race intervals and increased time since racing were associated with lower POD grades, which may indicate that lesions heal. Further work is required to enable optimisation of racing and training programmes to reduce the frequency and severity of this disease.

Project description:Simple Summary Many subclinical medical disorders are considered as possible causes of decreased performance in racehorses. The present study aims to evaluate the associations between different disorders diagnosed in 248 poorly performing Standardbreds and their racing outcomes in the periods of time around hospitalization and their lifetime careers. In particular, the effects of respiratory, cardiovascular, gastric, and muscular conditions on number of starts, wins, placings, and earnings were investigated. Inflammation of the lower airways was associated with worse racing results in the periods before and after hospitalization and with a shorter and less successful career, confirming its role in performance impairment. Other conditions negatively influencing short-term racing outcomes included dynamic obstructions of the upper airway and gastric ulcers, while the role of exertional rhabdomyolysis was not clear. Finally, exercise-induced pulmonary hemorrhage and cardiac arrhythmias did not seem to affect Standardbred trotters’ performance. Abstract Poor performance in racehorses is commonly associated with subclinical diseases. This study aims to evaluate the associations between medical disorders and racing results in Standardbred trotters. The clinical records of 248 poorly performing Standardbreds were retrospectively reviewed, and their racing results were extracted from an online database, concerning the periods 3 months before and 6 months after hospitalization and the entire lifetime. Generalized linear models were used to evaluate the effects of different disorders on racing outcomes. Airway neutrophilia was associated with limiting lifetime starts and wins pre- and post-hospitalization, while mastocytosis was associated with less wins in the post-hospitalization period. Therefore, lower airway inflammation showed both short- and long-term impacts on racing performance. Severe upper airway obstructions and gastric ulcers showed associations with less placings in the post-discharge period but no long-term influence on performance. The significance of exertional rhabdomyolysis was indeterminable, yet interference with the number of starts in the post-discharge period was reported and associated with lower total career earnings. Exercise-induced pulmonary hemorrhage and cardiac arrhythmias were not associated with worse racing outcomes: therefore, their role in poor performance remains unclear.

Project description:This article reports on the results of a survey designed to explore the types of nosebands that owners, riders and trainers use in training and competition, their reasons for using nosebands, the design preferences in different disciplines and approaches to noseband tightness and monitoring, as well as the incidence of negative impacts related to noseband usage. Respondents (n = 3040) were asked to specify the type of noseband they were currently using and to rate how effective they were in achieving these stated reasons. Respondents who used nosebands (n = 2332) most commonly used Plain Cavesson (46.6%, n = 1087) and Hanoverian (24.8%, n = 579) nosebands. The reasons provided in the survey for noseband usage were grouped into three broad, mutually exclusive categories: Anatomical; Consequential and Passive. Responses across these categories were fairly evenly distributed overall: Anatomical (29.5%, n = 1501), Consequential (30.6%, n = 1560), Passive (32.9%, n = 1673) and other reasons (7.0%, n = 358). Across all respondents (n = 2332), the most common Anatomical reason given was to prevent the horse's tongue from moving over the bit (20.8%, n = 485), the most common Consequential reason was to improve the appearance of the horse (20.4%, n = 476), with aligning with the rules of the sport (30.2%, n = 705) the most popular Passive reason. Of the respondents who answered the question of checking noseband tightness (n = 2295), most reported checking noseband tightness at the bridge of the nose (62.1%, n = 1426), some (10.4%, n = 238) reported checking for tightness on the side of the face and others under the chin (21.5%, n = 496). This survey also revealed some of the potential issues associated with noseband use, with 18.6% (n = 434) reporting at least one physical or behavioural complication. The most common complication was hair loss under the noseband (39.9%, n = 173). Crank systems were reported to be used by 28.9% (n = 665) of respondents. This is of concern as these devices can be excessively tightened, minimising jaw and tongue movement and may compromise horse welfare. Indeed, the current data in our study show that these devices are associated with an increased risk of complications being reported. Against the backdrop of potential harm to horse welfare associated with restrictive nosebands, this report may serve as a guide for future regulations and research. It helps improve our understanding of noseband preferences and their use in different disciplines.
