Oxidative stress profile during postpartum period in Surti goats

Present study was conducted to investigate postpartum oxidative stress in 20 Surti goats. Blood samples were collected on 0, 7^th, 14^th, 21^st, 30^th and 45^th days postpartum and analysed for Superoxide Dismutase (SOD), Glutathione Peroxidase (GPx), lipid peroxidation (LPO), reduced Glutathione (GSH) and uric acid. SOD differed significantly between 0, 14^th and 21^st day postpartum. GPx was significantly low on 14^th day and then increased significantly (P<0.01) up to 45^th day. Significant (P<0.01) difference was observed between days except 0 and 21^st. LPO increased significantly (P<0.01) from 0 to 14^th day and then decreased non-significantly up to 45^th day. Reduced glutathione was significantly (P<0.05) higher on 0 day. Uric acid was lowest on 0 day and highest on 45^th day however they were non-significantly different on 7^th, 14^th, 30^th and 45^th day. It can be summarized that on 14^th day post kidding, the values of SOD, GPx and GSH were lowest while LPO was highest. Uric acid was significantly (P<0.01) low on the day of kidding. Thus it may be concluded that in Surti goats the period from 0 day to 14^th day postpartum is most stressful and critical care should be taken during this period. GPx, SOD along with LPO and GSH can be used as marker of stress during postpartum period.
