The purpose of the present study was to investigate changes in hematological and serum biochemical parameters in ponies exercising 3 times a day. The study included 10 healthy 4- to 5-year-old Jeju crossbred ponies used in riding lessons at an equestrian riding school. Hematology and serum chemistry samples were obtained before the initial lesson and after the last lesson of the day. The post-exercise results showed that packed cell volume, white blood cell, red blood cell, hemoglobin, and total protein levels increased significantly (p < 0.05). Serum Na+ also increased significantly (p < 0.01), but serum Ca++ decreased significantly (p < 0.01). Creatinine kinase, aspartate amino transferase, gamma glutamyl transferase, blood urea nitrogen, creatinine, and bilirubin levels increased significantly (p < 0.05), but the glucose level decreased significantly (p < 0.05). Furthermore, the serum cortisol hormone level increased significantly (p < 0.01). The results suggest that participating in riding lessons three times a day may result in various physiological changes, indicating the presence of exercise-related stress in riding ponies.
