This study aimed to monitor the effect of a high (HD; 140% of energy requirements) versus a low diet (LD; 80% energy requirements) on oxidative status in goats during the peripartum period. Blood samples were taken from all goats at -2, -1, 0 (partum), +2 and +4 weeks from delivery. Blood samples were assayed for their content of reactive oxygen metabolites (ROMs), thiol (SH) groups, total antioxidant capacity (OXY) and for glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities. The observation that ROMs levels significantly increased during the peripartum period was accompanied by a decrease of GSH-Px activity at weeks 2 and 4 postpartum, which suggested that the goats mi..View full abstract
