Abstract

Blood samples were collected from 16 Thoroughbred horses before, during and after the second day of a 3-day event. Plasma osmolality, concentrations of sodium, potassium, chloride, urea, creatinine, glucose, bilirubin, iron, total protein, albumin, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, creatine kinase, calcium, inorganic phosphate, uric acid, cholesterol, triglycerides and non-esterified fatty acids were measured. Significant differences from pre-event values were found in all parameters with the greatest changes being found after the cross-country phase. Most parameters showed significant rises following exercise, except calcium and chloride, which decreased. It was deduced from the changes in biochemistry that dehydration, reduced glomerular filtration rate, increased glycogenolysis and increased lipid metabolism, were a result of this form of competitive exercise.
