Selenium and Vit. E as Related to Growth and White Muscle Disease in Lambs. ∗

Abstract

Summary

1) Selenium, given pre-natally per os to ewes or post-natally by injection to lambs, prevented WMD and resulted in increased growth of lambs as compared to untreated controls. 2) Growth response to selenium fed pre-natally was greater than that to selenium injected post-natally. 3) Massive doses of Vit. E at birth protected lambs from WMD, but did not result in improved growth. 4) Evidence suggests an essential role for selenium in supporting growth of lambs.
