Growth and the Somatotropic Axis in Young Thoroughbreds
… between ADG and IGF-I was described in Thoroughbreds from birth to 16 mo of age. Feeding diets to the foal that influence the somatotropic axis during growth may affect development of growth cartilage in unexpected or detrimental ways. The pattern of weight in Thoroughbred foals from …

Environmental factors, pasture composition, growth rate and puberty in growing Thoroughbreds
… measures from birth through 16 mo in young Thoroughbreds. Growth data and plasma samples were collected monthly from 3 annual crops of 20 foals. Plasma progesterone (P4) and insulin like growth factor one (IGF-I) concentrations were measured with previously validated radio immunoassay's …

Growth of Thoroughbreds fed Different Levels of Protein and Supplemented with Lysine and Threonine
Currently accepted optimum protein levels for growth in the horse may be reduced with amino acid supplementation. This study investigated the effects on growth and protein status of Thoroughbred foals offered a supplement with a typical CP level to a supplement that had a lower CP level fortified …

Estimation of relatedness of thoroughbreds and eight breeds of horses using DNA fingerprinting of whole blood
… the probes screened. The level of inbreeding in Thoroughbreds has been estimated by comparing the number of bands shared among these animals to a quasi-natural population (Mustang) and a theoretically known genetic relationship (a sire and his offspring). Using the probes CAC5 and YNZ 132 …

An Investigation of Humeral Stress Fractures in Racing Thoroughbreds Using a 3D Finite Element Model in Conjunction with a Bone Remodeling Algorithm
The humerus of a racing horse Thoroughbred is highly susceptible to stress fractures at a characteristic location as a result of cyclic loading. The propensity of a Thoroughbred to exhibit humeral fracture has made equines useful models in the epidemiology of stress fractures. In this study, a …

METABOLIC CHARACTERISTICS AND SUSCEPTIBILITY TO LAMINITIS IN MORGAN AND THOROUGHBRED HORSES
… In practices limited to either Quarter Horses or Thoroughbreds (the two most common breeds in the United States), the Quarter Horse was found to have an incidence of laminitis eight times greater than the Thoroughbred, and the recovery rate of the Quarter Horse is 1.3 times higher. Thoroughbreds, …

The effects of hyaluronic acid and exercise on equine skeletal muscle
… for anti-inflammatory properties. Unfit, adult Thoroughbreds were intravenously injected three times with HA or received no injection at all (CON) over a 3-week period before performing a single submaximal exercise test. Gluteal muscle biopsies were collected before and 1 h after the completion …

PULMONARY ARTERY STIFFNESS IN RACEHORSES AFFECTED BY EXERCISE-INDUCED PULMONARY HEMORRHAGE
… EIPH itself. Third, PAS was measured in 40 Thoroughbreds using the left parasternal angled view of the right-ventricular outflow tract, and repeatability/reproducibility were assessed. Intra-operator agreement was excellent, while inter-operator agreement ranged from moderate to excellent. A …

Vitamin E Status of Thoroughbred Horses and the Antioxidant Status of Endurance Horses
… in horses to a limited degree but not in grazing Thoroughbreds, thus the MARE Center gave me the opportunity to study vitamin E in Thoroughbred mares and foals. Middleburg is located in the Blue Ridge Mountains on Northern Virginia close to the site of one of the toughest endurance races in the …

Genetic investigation of recurrent exertional rhabdomyolysis risk and performance in racehorses
… further demonstrate the complex nature of RER in Thoroughbreds and Standardbreds. The majority of the heritability was explained by SNPs with large and medium effect sizes, providing evidence for the feasibility of a multi-marker assay for RER risk prediction in these two breeds. Single- and …

Impact of Training Method on Behavioral, Physiological, and Relationship Measures in Horses
With a rise in concern for animal welfare, the equine world has started using positive reinforcement (R+); as such, horses often experience a combination of negative reinforcement (R-) and R+. I compared the effects of R- to a combination of positive and negative reinforcement (R-/R+) training. …
