Effects of seasons on some physiological parameters in Karya sheep

2016 Research Opinions in Animal and Veterinary Sciences  
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
