INFLUENCE OF TROTTING END GALLOPING EXERCISES ON ERYTHROGRAM OF ANDALUSIAN HORSE STALLIONS

Possible alterations in the erythrogram and in red blood cell volume i ndices were studied in ten Andalusian stallions subjected to two diffe rent types of exercise (trotting and galloping). For this purpose, the changes in these blood parameters were measured during resting, immed iately after the exercise finished, and at 5, 10 and 30 min. of recove ry. From the results it was deduced that the red blood cell count (RBC ), the hematocrit value (PCV) and the concentration of hemoglobin (HE) increased significantly (p less than or equal to 0.05) after finishin g both types of exercise, with a greater increase with galloping. The return to baseline values was faster for trotting than for galloping. However, the RBC volume indices (mean corpuscular volume, mean corpusc ular hemoglobin and mean corpuscular hemoglobin concentration) did not undergo any significant changes with either type of exercise.
