| heal.abstract |
Under hot summer conditions dairy ewes of the Chios and the Karagouniko breed had respiration rates (breaths/min) above normal, whereas their body temperature (°C) was not affected. The two breeds expressed thermal behavior directly related to the black-globe temperature. As heat ensued towards noon (i.e. increased values of the Daily THI-hrs index), the apparent short-term heat-stress of the Chios ewes was milder than that of the Karagouniko ewes as indicated by the significantly lower respiration rate (08:00h: 55.1±1.6 for the Chios breed vs. 78.5±2.6 for the Karagouniko breed; 14:00h: 62.8±1.8 for the Chios breed vs. 91.1±2.4 for the Karagouniko breed). No body temperature difference was detected. Future experiments have to be conducted to integrate the Daily THI - hrs index with solar radiation and wind speed aiming at better explaining the apparent sheep heat-stress. |
