A study was conducted to assess the oxidative stress status of cross bred Malabari goats during peripartum period. Serum levels of malondialdehyde (MDA), a degradation product of lipid peroxidation, reduced glutathione (GSH), serum ascorbic acid and oxidative stress factor (OSF) were used to assess the oxidative stress status of animals in advanced pregnancy, day of kidding and one week after kidding. Changes in haematology (PCV and Hb) associated with pregnancy and kidding were also analyzed. The results of the study showed that MDA and OSF were significantly (P£0.01) increased in animals on day of kidding and one week after kidding when compared to non pregnant animals. Serum ascorbic acid concentration of animals was reduced on day of kidding and one week after kidding. Lowest ascorbic acid concentration was noticed at one week after kidding. However, serum GSH level was not significantly affected either by pregnancy or by kidding. Haemoglobin level of pregnant animals was significantly higher (P£0.05) when compared to that of non- pregnant animals.
