Blood samples were collected at 4 time points under different environmental conditions (T1, T2, T3 and T4) and analysed for haematological parameters.

The majority of haematological values obtained in the present study, even though within the physiological range for cattle, showed that variations in haematological parameters are related to changes in ambient temperature, relative humidity and temperature-humidity index. These results provide insight into the physiological responses of Piemontese cows to different environmental conditions, allowing to better evaluate its ability to adapt and cope with environmental stress.
