Production of higher level of reactive oxygen species (ROS) than normal level causes oxidative stress to the cells, leading to lipid peroxidation (LPO) and ultimate tissue damage. The endogenous antioxidant system present in the body neutralizes ROS produced in the cells. Selenium (Se) and vitamin E play an antioxidant role and help to scavenge the ROS in the body system. The normal dietary recommendation of Se is approximately 0.1-0.3 ppm of DM intake in dairy cattle. The recommended requirement of vitamin E is about 80 IU/kg DMI in the dry and post-partum period; and about 20 IU/kg during lactation in case of dairy cattle. Both the selenium and vitamin E separately and in combination have potential effects on reproductive health in dairy cattle, especially during the transition period. Deficiency of these may cause free radical accumulation and damage to cell membranes which further disrupt several processes including steroid hormone and prostaglandin synthesis, impaired immune system, lower reproductive performance and reproductive disorders. Normally animals get these two important antioxidants from their natural diet. But if the diet is deficient, then, supplementation is recommended. Supplementation of Se and vitamin E during pre partum period decreases the occurrence of post partum complications in dairy cattle.
