Selenium metabolism in the chick and effects of Vitamin E and selenium on heat stress

Creator:: Alayan, Mohammad Atta
Abstract:: An in vitro study was conducted to investigate the metabolism and distribution of Se⁷⁵-selenite and Se⁷⁵-selenomethionine (SEM) in chick blood. Se⁷⁵-selenite is taken up by RBC (13% within 20 minutes) and expelled into the plasma to become bound to proteins. In contrast, Se⁷⁵-SEM showed a more gradual and continuous buildup...
