Endurance horses are able to run at more than 20 km/h for 160 km (in bouts of 30-40 km). This level of performance is based on intense aerobic metabolism, effective body heat dissipation and the ability to endure painful exercise. The known heritabilities of endurance performance and exercise-related physiological traits in Arabian horses suggest that adaptation to extreme endurance exercise is...

BACKGROUND: Equine metabolic syndrome is an endocrinopathy that affects different breeds of horses and ponies. This metabolic disorder is a multifactorial syndrome and it is primarily linked to obesity, dyslipidemia and insulin resistance.

DESIGN Cohort study of ocular structures and retrospective case series of horses with and wit...

The medical records of 41 racing Standardbreds, diagnosed as having dorsal displacement of the soft palate (DDSP), that underwent sternothyroideus myotomy and soft palate resection were reviewed. All horses had endoscopy of their upper respiratory tract, but not necessarily by Dr. Llewellyn.a The history had to confirm the diagnosis of DDSP. Surgery in each patient was performed by Dr. Llewelly...

The purpose of this study was to assess the efficacy riboflavin/UV-A corneal phototherapy in comparison with topical antimicrobials for treatment ulcers horses. Nineteen horses a diagnosis ulceration were randomised receive either (11 horses) or antimicrobial therapy (8 horses). consisted application riboflavin-enriched ophthalmic solution onto cornea 20 min followed by UV-A irradiation at 30 m...

The intestinal tract houses one of the richest and most complex microbial populations on the planet, and plays a critical role in health and a wide range of diseases. Limited studies using new sequencing technologies in horses are available. The objective of this study was to characterize the fecal microbiome of healthy horses and to compare the fecal microbiome of healthy horses to that of hor...
