Amelioration of altered oxidant/antioxidant balance of Indian water buffaloes with subclinical mastitis by vitamins A, D^sub 3^, E, and H supplementation

The effect of vitamins A, D^sub 3^, E, and H supplementation on oxidative stress indices in Indian water buffaloes suffering from subclinical mastitis was investigated. Changes in the total oxidant capacity (TOC), total antioxidant capacity (TAC), nitric oxide (NO), and activities of glutathione peroxidase (GSH-Px), catalase (CAT), and superoxide dismutase (SOD) in milk were evaluated before and after the supplementation of vitamins A, D^sub 3^, E, and H. The buffaloes suffering from subclinical mastitis revealed remarkable alterations in the milk oxidants/antioxidants balance shifted towards oxidative status. The buffaloes with subclinical mastitis revealed significantly (Pâ[euro][per thousand]â[per thousand]¤â[euro][per thousand]0.01) higher TOC, NO contents, and CAT activity, while TAC content and GSH-Px activity were significantly (Pâ[euro][per thousand]â[per thousand]¤â[euro][per thousand]0.01) lower in comparison with the healthy controls. However, SOD activity did not show any significant change. Supplementation of vitamins A, D^sub 3^, E, and H to these animals revealed significant (Pâ[euro][per thousand]â[per thousand]¤â[euro][per thousand]0.01) reduction in TOC, NO, and CAT, while a significant (Pâ[euro][per thousand]â[per thousand]¤â[euro][per thousand]0.01) increase in TAC and GSH-Px activity was also evident. From the present study, it may be concluded that supplementation of these vitamins can help ameliorate the altered milk oxidants/antioxidants balance towards normalcy and, thus, ensue recovery from subclinical mastitis in the Indian water buffaloes.[PUBLICATION ABSTRACT]
