The Influence of Pregnancy and Lactation on Plasma Antioxidant Status in Aardi Goats

The aim of this study is to assess the effects of pregnancy and lactation on selected antioxidant profi le in Aardi, goats. Blood samples were taken from sixteen goats approached 3-4 months of pregnancy, and a month before parturition, blood samples were taken, and weekly until parturition, and then every week until four weeks postpartum. The total antioxidant concentrations increased during the 4th to the 2nd week before parturition, and started to decline until partition, and continued the decline until the second week after parturition, then increased again. Serum Thiobaributric Reactive Substances (TBARS) concentrations follow similar pattern to Total Antioxidant Concentration (TAC). Immediately after parturition, there was an increase in TBARS, and then by the end of 1st week started to decrease until the 4th week postpartum. Low serum Super Oxide Dismutase (SOD) four weeks postpartum, might be related to the lower activity of reactive oxygen metabolites, as indicated by the increased antioxidant capacity. Superoxide dismutase increased on the 2nd week postpartum up to the 4th week postpartum.In conclusion, this data about local goats will be benefi cial for understanding the basic adaptive physiological biomarker.</p
