Abstract

Objective : Among experimental animal models, horses are the most adaptable to exercise and this ability has been extensively studied. Research on equine exercise physiology is mostly focused on genetics, and few integrated studies have focused on equine metabolomics. This study were conducted to analyze metabolites in plasma, urine, and sweat samples collected from Jeju pony and thoroughbred horses before and after exercise. In this study, we analyze the various equine samples using NMR (nuclear magnetic resonance) spectroscopy. Methods : 1 H NMR spectroscopy analysis were conducted with equine plasma, urine, and sweat samples collected from Jeju pony and thoroughbred horses before and after exercise. Relative metabolite levels between three types of were compared under exercise stimuli and by breeds. Results : A total 26, 39, and 36 metabolites were identified in each of plasma, sweat, and urine samples, respectively, of both thoroughbred and Jeju pony. A total 3, 12, 15 metabolites were exclusively detected in plasma, sweat, and urine samples, respectively, and 15 metabolites were detected in all samples at the same time. In addition, total 8 and 5 metabolites were detected after exercise in plasma and urine samples. Additionally, we obtained 16, 6, and 30 metabolites in plasma, urine, and sweat by breeds.
