Valori ematologici ed ematochimici in cavalli trottatori in funzione della categoria da corsa

The influence of race-category (2 years, 3 years, 4 years old horses and "5 years old and more" horses) on haematological parameters in Standardbred Trotters trained in Puglia was studied. The research's duration was one year and a blood sample was collected, a week after the last race, from 75 health Trotters with good records. The datum acquired were studied to show statistical difference on the basis of race-category and the mean values were compared with normal range reported in bibliography for "warm blood horses".The category of "2 years old horses" showed packed cells volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) lower and alkaline phosphatase (AP), calcium and phosphorus higher than other race-category. "3 years old horses" category showed maximal value of leukocytes, alpha and gamma globulins. Values of "4 years old horses" category were always in normal range. The race-category of "5 years old and more horses" showed maximal value for MCV, MCH and bilirubin
