Blood metabolic profiles are widely used to monitor health, reproductive and nutritional status. In the last few years, the evaluation of oxidative stress level of the organism has contributed increasingly as a complementary tool in the evaluation of metabolic status. The aim of this paper was to investigate the possible influence of age and physiological status on blood metabolic profile: Hb, PCV, TP, Creatinine, Glucose, TL, Cholesterol, Triglycerides, ALT and AST in ewes. We also measured two antioxidant enzymes, GPx and SOD to evaluated the oxidative stress level and establish the relationship between those and variation of biochemical parameters. The results showed that all the blood parameters determined in serum, were within or close to normal range value for healthy ewes and were significantly (P<0.05) affected by the age and variations of physiological status. A strong correlation (P<0.01) was observed in lactation period between antioxidant enzymes and lipid profile. Taking the results together suggests that age and physiological status have to be taken into consideration for a correct interpretation of the serum chemistry values of sheep.
