Thermal stress redistributes the body resources including protein and energy at the cost of decreased growth, reproduction, production and health. In this study, seasonal variations of body temperature, heart and respiratory rates, and level of serum cortisol and cholesterol were investigated in Karya sheep. Heart rate was significantly higher (P<0.05) in winter and significantly low (P<0.05) summer. The respiration rate was significantly higher (P<0.05) in summer and significantly (P<0.05) low in winter. Similarly, body temperature was significantly higher (P<0.05) low in spring and summer. Serum cholesterol and cortisol increase significantly (P<0.05) during summer. The studied parameters in Karya sheep may provide a baseline data for the future studies.
