HEMATOLOGICAL AND BIOCHEMICAL-CHANGES IN THE BLOOD OF EWES AND LAMBS AFTER SELENIUM AND VITAMIN-E INJECTION

The effect of barium selenate injection in sheep anal the administrati on of selenium and / or vitamin E in lambs during the first days of li fe on some haematological and biochemical parameters was studied. The administration of barium selenate in sheep (50 mg / animal) 3 weeks be fore the introduction of the males increases significantly (P < 0.01) the GSH-Px activity during gestation and post-partum. Lambs born from injected ewes had a higher GSH-Px activity (P < 0.01) in the first wee k as well as three weeks later. Lambs injected with 3 mg of selenium a nd 100 mg of vitamin E in the first week of life had high GSH-Px activ ity 3 weeks later. The lambs injected with 100 mg of vitamin E in the first week of life had GSH-Px activity similar to that of the control group. Lactate dehydrogenase, creatine kinase, aspartate amino transfe rase and haematological parameters were almost similar in all animal g roups. The results show that barium selenate injection.
