Energy, oxidant-antioxidant status and trace mineral in Beetal goats

The present study was aimed to evaluate the oxidative stress around the puerperal period in Beetal goats in relation to parity. A total of 30 Beetal goats reared under semi-intensive system were divided into three groups with 10 animals each viz. Gr-A (early parity; 1-2 parity), Gr-B (Mid parities; 3-6 parity) and Gr-C (late parities; >7 parity). Blood samples were collected from 3 weeks and 1 week pre-kidding followed by 1, 2, 4 and 8 weeks post-kidding for the estimation of oxidant (malondialdehyde (MDA)) and antioxidant (SOD, CAT, GSH-Px, GSH and GST activity and trace minerals, zinc and copper). Findings highlight a different metabolic, trace mineral (zinc and copper), and oxidative response around the periparturient period in Beetal goats, with the early parity goats, responding first to increased metabolic and oxidative stress and also first to recover from oxidant/antioxidant imbalance.
