Blood phagocyte activity after race training sessions in Thoroughbred and Arabian horses

Intensive exercise and exertion during competition promote many changes that may result in the impairment of immunity and increased susceptibility to infections.

Description
Summary:Intensive exercise and exertion during competition promote many changes that may result in the impairment of immunity and increased susceptibility to infections. The aim of this study was to evaluate the activity of “the first line of defense”: neutrophils and monocytes in racing Thoroughbred and Arabian horses after routine training sessions. Twenty-three (12 Thoroughbred and 11 Arabian) horses were examined. Routine haematological (number of red blood cells – RBC, haemoglobin concentration – HGB, haematocrit – HCT, total number of white blood cells – WBC), biochemical (creatine phosphokinase activity – CPK and total protein concentration – TP) parameters, cortisol concentration as well as phagocytic and oxidative burst activity of neutrophils and monocytes were determined. The values of basic parameters and the activity of phagocytes differed between breeds and distinct patterns of exercise-induced changes were observed. The training sessions did not produce the decrease in phagocyte activity that might lead to the suppression of immunity.
