Lipid peroxidation and antioxidant vitamins in postpartum anoestrus buffaloes supplemented with vitamin E and selenium

摘要

Fifteen Murrah buffaloes were divided into three groups: group I-normal cyclic; group II-postpartum anoestrus and group III-postpartum anoestrus buffaloes supplemented with i/m injections of vitamin E and selenium containing 500 mg alpha-tocopherol acetate and 15 mg selenium at weekly intervals for two months. Group II buffaloes had significantly higher level of lipid peroxidation and lower levels of plasma vitamin E and beta-carotene as compared to normal cyclic buffaloes of group I. Supplementation of vitamin E and selenium lead to significant decrease in the level of lipid peroxidation accompanied by increase in the levels of plasma vitamin E and beta-carotene in group III buffaloes. All the five animals in group III became cyclic by day 30.8 +-7.16 and three became pregnant by the day 19.7 +- 2.21 since beginning of supplementation, showing 60 percent conception rate.
