Sulphur Metabolism and Excretion Studies in Ruminants IX. Sulphur, Nitrogen, and Energy Utilization by Sheep Fed a Sulphur-Deficient and a Sulphate-Supplemented, Roughage-Based Diet

Abstract

Four Merino wethers were each fed a sulphur-deficient, roughage-based ration containing 1'05% nitrogen (79% as urea) and supplying 135 mg sulphur/day. Four other sheep were fed similar amounts of basal ration supplemented with NasS04. This ration supplied 494 mg sulphur/day. Mter 21-day periods the treatment groups were reversed.
