Effect of α-Tocopherol Supplementation on Plasma Levels of Antioxidant Vitamins in Anestrus Buffalo Heifers (Bubalus bubalis)
R. S. Kahlon, Rajvir Singh
Abstract
The present investigation was undertaken to study the status of plasma antioxidant vitamins in normal cycling and -tocopherol supplemented anestrus buffalo heifers. The pre-supplementation plasma levels ( mol/L) of vitamin E and -carotene were significantly (p<0.05) lower and of vitamin C was significantly (p<0.05) higher in anestrus heifers (4.06 0.07; 4.56 0.17; 21.04 0.21) when compared to normal cycling ones (4.92 0.05; 6.76 0.12; 14.24 0.16). The oral supplementation of -tocopherol at 3,000 mg per week per animal in anestrus heifers resulted in a significant (p<0.01) increase in vitamin E and -carotene levels and a significant (p<0.01) decrease in vitamin C concentration. Results indicated that supplementation of -tocopherol to anestrus buffalo heifers improved the antioxidant status by mitigating the harmful effects of free radical induced oxidative stress.
