The aim of present study was to evaluate the effects of the hot climate on the oxidative status of native goats. Blood samples were taken in pre summer and summer and oxidative stress was evaluated by determining various serum biomarkers glutathione reductase (GSH), superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT) and haematological parameters (packed cell volume and haemoglobin). The reference values for oxidative stress parameters of adult clinically healthy native goats were as followed : SOD 778.65-1190.50 U/g Hb, GSH 266.67-322.74 U/g Hb, CAT 1536.29?2215.63 U/g Hb and MDA 0.346-0.801 ?mol/l (Nazifi et al.,2009). Stressed goats exhibited lower levels of haemoglobin and packed cell volume. The activity of glutathione reductase and superoxide dismutase increased significantly. It was concluded that oxidative stress was increased in goats during summer.
