Summary This report describes a case of chronic haematoma formation secondary to repeated hindlimb interference injuries in a 4‐year‐old Standardbred trotter racehorse. Physical examination, radiography and ultrasonographic investigations identified a firm, encapsulated soft tissue mass on the medial aspect of the left mid‐metatarsal region. After surgical removal, histopathological examination confirmed a chronic haematoma. The horse responded well to surgical management of the condition. To the authors’ knowledge, this is the first report of surgical intervention to resolve the common problem of repetitive interference injuries in Standardbred racehorses.

“…In addition, 5% have rhabdomyolysis yearly (Isgren et al, 2010), and up to 5.7% of Standardbred horses and 25.6% of Thoroughbred horses show stereotypic behavior (Redbo et al, 1998). However, the most common problem among both Standardbred and Thoroughbred horses appears to be lameness (Vigre et al, 2002;Dyson et al, 2008). Taken together, these figures indicate that there is a need for improved management of racehorses to prevent health-related problems and promote a successful career.…”

“…Surprisingly, there are very few, if any, holistic studies in which training, diet, growth and health in young racehorses have been documented and evaluated under longterm, controlled conditions. However, there are some field -E-mail: anna.jansson@huv.slu.se studies documenting age and/or training-induced metabolic changes (Lindholm and Piehl, 1974), growth (Thompson, 1995) and health (Vigre et al, 2002;Dyson et al, 2008) separately.…”

The aim of this study was to, from a holistic perspective, describe the effects of a forage-only feeding system and a conventional training program on young Standardbred horses and compare data with similar observations from the literature. Sixteen Standardbred colts fed a forage-only diet for 4 months from breaking (August to December) and with the goal to vigorously trot 5 to 7 km at a speed of 5.6 m/s (3 min/km) were studied. The horses were fed grass haylage (56 to 61% dry matter (DM), 2.80 to 3.02 Mcal DE/kg DM and 130 to 152 g CP/kg DM) ad libitum, 1 kg of a lucerne product and minerals. The amount of training and number of training sessions were documented daily, and feed intake and body development were measured once every month. Heart rate (HR) was measured during and after a standardized exercise test in October and December. In December, a postexercise venous blood sample was collected and analyzed for plasma lactate concentration. Muscle biopsies (m. gluteus medius) were taken and analyzed for glycogen and fiber composition. Health was assessed in October and November by an independent veterinarian using a standardized health scoring protocol. BW and height at withers increased from 402 to 453 kg (root mean square error (RMSE) 6) and from 148.7 to 154.1 cm (RMSE 0.7), respectively, and the body condition score was 4.9 (RMSE 0.2) at the end of the study. Muscle glycogen content was 532 mmol/kg dry weight (s.d. 56). There was a significant decrease in postexercise HR (81 v. 73 bpm, RMSE 8), and the individual amount of training was negatively correlated with HR during and after exercise. Health scores were high and similar at both assessments (8.4 and 8.4 (RMSE 1.0) out of 10; P . 0.05), and the number of lost training days per month due to health problems was ,0.9, with the exception of November (5.3 days). It is concluded that yearlings in training fed high-energy forage ad libitum can reach a conventional training goal and grow at least as well as earlier observations on yearlings of other light breeds.

“…Trotting horse trainers consider soundness as a lack of injuries because injuries have a negative influence on training and racing (Magnusson & Thafvelin 1990). Racing success of trotters depends partially on good health which enables optimal training (Saastamoinen 1991; Vigre et al. 2002).…”

Genetic correlations for body measurements and conformation and functional traits in foals and studbook horses with racing traits were estimated in the Finnhorse and Standardbred. Genetic response and accuracy were estimated using records of animal, half-sibs and parents in selection scenarios for racing traits, for foal and racing traits, for studbook and racing traits, and using records of animal, half-sibs and parents for foal traits and racing traits of parents. Racing time and earnings were the breeding objective. Low-to-moderate genetic correlations for body measurements and racing traits indicated that selection favours bigger horses at all ages. Being mainly favourable for the breeding objective, genetic correlations for conformation and functional traits with racing traits were highest for the foal traits of type, trot and overall grade and for the studbook traits of character and movements. Genetic correlations for foal and studbook conformation with racing traits were low in the Finnhorse and moderate to high in the Standardbred. In foals, the highest genetic correlations were for trot with racing time (-0.54) and with earnings (0.52) in the Finnhorse, and for overall grade with racing time (-0.54) and with earnings (0.54) in the Standardbred. In studbook horses, genetic correlations were high for character with racing time and earnings in the Finnhorse (-0.68, 0.61) and in the Standardbred (-0.63, 0.70), and for movements with racing time and earnings in the Finnhorse (-0.70, 0.69) and in the Standardbred (-0.90, 0.88). To increase accuracy of conformation and functional traits, foal traits would be more useful in the index with racing traits, as being less preselected than studbook traits. The foal traits (type, trot, overall grade) having moderate heritability and genetic correlations with racing traits would be useful in multi-trait index before a racing career, where the greatest gain is because of a shorter generation interval. It would be feasible to implement for AI stallions.
