|
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. |
