Dairy industry is gradually emerging as a major player in the field of agricultural economy. Consequently the management scene and concomitant disease control regimen have become more important for production and economic reasons. Despite innovations in various therapeutic regimens and improved management practices, mastitis unfortunately has remained ever green. Mastitis is a multi-etiological complex disease, which is defined as inflammation of parenchyma of mammary glands and is characterized by physical, chemical and usually bacteriological changes in milk and pathological changes in glandular tissues (Radostits et al., 2010). Mastitis may be classified as clinical and subclinical. In contrast to visible changes in the clinical form of mastitis, there is absence of gross abnormalities in the milk or udder in case of subclinical mastitis. The average incidence of clinical mastitis varies from 10 to 20 % in most of the herds and the prevalence of intra mammary infection is around 50 % of quarters (Radostits et al., 2007). Further, the subclinical mastitis (SCM) is 3– 4 times more prevalent than clinical mastitis (Bhanderi and Garg, 2012). Therefore, milk production loss is more in subclinical mastitis as compared to clinical form because of increase in undesirable milk components like proteolytic enzymes (Pyorala, 2003), salts and also increase in somatic cell count, thereby resulting in decrease in the desirable components such as protein, milk fat and lactose. The present study was conducted for investigating the alterations in the activities of erythrocyte glutathione peroxidase (GSH-Px) and its functional components in cows with subclinical mastitis and normal cows of Odisha along with the therapeutic efficacy for antioxidants along with antibiotics on restoration of changes in oxidative stress indices.
