Body weight, hematologic findings, and serum and plasma biochemical findings of horses competing in a 48-, 83-, or 159-km endurance ride under similar terrain and weather conditions.
This study was conducted to compare physiologic, hematologic, and selected serum and plasma biochemical variables obtained from horses competing in 48-, 83-, or 159-km endurance rides before competition and at the same cumulative distance points. The authors executed weight and rectal temperature measurements and also blood samples were obtained from 83 horses before, during, and after 1 of 3 rides conducted on the same day. Plasma protein (PP), lactate, WBC, serum electrolyte, and calcium concentrations; PCV; and creatine kinase (CK) activity were determined. A practical conclusion of the authors was that electrolyte and water supplementation and earlier arrival at the event may be beneficial for horses that are transported long distances to endurance competition.
