A study was carried out in Indian indigenous pigs to assess the changes in the levels of antioxidant enzyme superoxide dismutase (SOD), during varying ambient temperatures. Blood samples were collected during moderate, extreme hot and cold ambiences to harvest sera. Mean value of serum SOD during the moderate period was 155.25 ± 1.47 kU L-1. Moderate ambience mean value was considered control. The mean value of serum SOD was significantly (p≤0.05) higher during hot and cold ambiences as compared to the control. Mean SOD value was 2.87 times higher in hot ambience and 1.77 times higher in cold ambience as compared to the moderate ambience. Increased SOD activities during extreme ambiences showed the presence of oxidative stress. Sex and age effects were significant (p≤0.05) in all the ambiences and were consistent during extreme ambiences inferring that serum SOD activities showed the interactions of ambience with sex and age. Present study provided data of SOD in indigenous pigs, which can be used as reference values for future studies and for diagnostic purposes. The archetype of changes of SOD activity revealed modulations of the adaptive mechanisms aimed to shield the pigs from alterations in ambient temperatures. Using this foundation of knowledge, antioxidant administration is recommended during extreme ambiences. [ABSTRACT FROM AUTHOR] |
