Cravana, C. and Manera, M. and Medica, Pietro and Fazio, Esterina and Ferlazzo, Adriana (2013) Modificazioni endocrino-ematologiche in cavalli P.S.I. in corso di prove di cross-country a differente altitudine.

The endocrine and hematological changes were studied in 24 healthy horses before and after cross-country sessions, performed at different altitudes. On the basis of different altitude and stabling, horses were distinguished in group I (200 m), group II (500 m), group III (800 m), group IV (control group: 1200 m). Compared to basal values, horses submitted to cross-country sessions showed higher cortisol levels post exercise, both at T1 (after the 1st hour) and T2 (after the 2nd hour), irrespective of different altitude, with significant effects of exercise on cortisol changes. Significant effects of different altitude were observed on the post-exercise cortisol changes in group I and III. Compared to basal values, Wbc, Rbc Hgb, Plt and Pct were higher after exercise, at T1, both in group I and group II, with higher Plt and Pct after exercise (T1) in group III. Basal Wbc, Rbc, Hgb, Hct and Plt values of groups III and IV were significantly higher than basal values of group I. Statistical analysis showed significant effects of exercise and altitude on the hematological variables.
