Occurrence of oxidative stress in sheep during different pregnancy periods

The objective of this paper was to evaluate oxidative stress during different pregnancy stages in Lohi sheep reared Libya. Investigations were carried out on between 1.5 and 5 years age. A total 40 sub-grouped into various along with non-pregnant controls as follows: (n=10), early mid late (n=10). Blood samples collected from pregnant preserved at -20°C further used for evaluating the concentrations antioxidant status (TAS), oxidant (TOS), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), paraoxonase (PON-1). In sheep, TAS, TOS, MDA, SOD, CAT, PON-1 values significantly (P < 0.05) different. TOS MDA increased ewes early, whereas decreased progression pregnancy. study suggests that use markers blood metabolic profile should be recommended procedure monitoring health evade reduced productive performance economic losses.
