Abstract:
Selenium supplementation by injection is a common practice. Acute toxicosis from dosaging errors may occur. In this report, 23 of 56 ewes and all 24 lambs injected with selenium died. Tissue, whole blood, and serum concentrations aided in the diagnosis. Caution should be taken when supplementing selenium by injection.
