Abstract:
This study was an effort to find out if season influences the key physiological and haematological parameters in Sahiwal indicine cows. The physiological data of 50 Sahiwal cows, and haematology of 15 Sahiwal cows per season was evaluated, so that a total of 400 physiological observations and 60 haematological observations across four seasons spanning one year was made. The prevailing microclimatic variables (temperature and relative humidity) were recorded to derive the Temperature Humidity Index (THI). The effect of seasons was evaluated using the correlation. Statistical analysis revealed the physiological parameters to be positively correlated with the THI, whereas most of the haematological parameters were negatively correlated with the THI.
