The present investigation was undertaken to study status of erythrocytic antioxidant enzymes in normal cycling and - tocopherol supplemented anestrus buffalo heifers. The pre-supplementation erythrocytic activities of superoxide dismutase (U/mg Hb), glutathione peroxidase (U/mg Hb) and glucose-6-phosphate dehydrogenase (U/g Hb) upregulated significantly (p<0.05) in anestrus heifers (, , ) when compared to normal cycling ones (, , ). The oral supplementation of -tocopherol (a) 3,000 mg per week per animal in anestrus heifers declined erythrocytic superoxide dismutase and glucose-6-phosphate dehydrogenase activities significantly (p<0.01) but led to non-significant increase in erythrocytic glutathione peroxidase activity. Results indicated that supplementation of -tocopherol to anestrus buffalo heifers mitigated the effects of oxidative stress to improve their antioxidant status.
