Abstract: Serum Superoxide Dismutase (SOD) profiling was carried out in the Marwari breed of sheep from arid tracts in India. Animals were categorized according to sex and age. Blood samples were collected during moderate, extreme hot and cold ambiences to harvest sera. Mean value of serum SOD during moderate ambience was 171.76±2.72 kU L-1. Moderate mean value was considered as control. The mean value of serum SOD was significantly (p≤0.05) higher during hot and cold ambiences as compared to control. Mean value was 2.57 times higher in hot ambience and 1.54 times higher in cold ambience as compared to control. The sex and age effects were significant (p≤0.05) in all ambiences. The mean values were significantly (p≤0.05) higher in male animals than female animals. In each ambience the age effect showed a significant (p≤0.05) increase in the mean values being highest in the animals of 2.5-4.5 years of age. Increased SOD activities during extreme ambiences indicated the development of oxidative stress. Present study generated data of SOD which can be used as reference values for future studies and for diagnostic purposes. The pattern of variation of SOD activity indicated modulation of adaptive mechanisms to protect the body from changes in ambient temperatures and on this basis use of antioxidants in the animals during changing environments is recommended.
