Sulphur-Selenium Studies in Sheep I. The Effects of Varying Dietary Sulphate and Selenomethionine on Sulphur, Nitrogen and Selenium Metabolism in Sheep

Abstract

Sulphur, selenium and nitrogen metabolism were studied in Merino wethers fed for 35-day periods on semi purified diets in which the sulphur content was increased to either 0·07 or 0·20 % by the addition of sodium sulphate. At both levels of sulphur, additions of selenium as DL"selenomethionine increased the basal level of selenium (0· 02Ilg/g) to 0·06, 0·09 and 0·67 Ilg/g.
