[Nutritional Biochemical Aspects of the Significance, of the Utilization, of Metabolism and of the Administration of Vitamin E and of Selenium in Sheep (review)]

A review is given on the significance, availability, metabolism and application of vitamin E and selenium in sheep. Vitamin E deficiency commonly occurs in spring. Selenium deficiency occurs in certain areas where the selenium content of plants is low. A further factor is the low availability of selenium as a consequence of reduction reactions in the forestomachs. When the supply of vitamin E and selenium is suboptimal, activity of the immune system and growth are impaired.
