Abstract

16 intact West African dwarf goats and eight fistulated sheep weighing 10-23 kg were used to study the effects of elemental S at four levels, none, 0.25, 0.50 and 0.75%, on the utilization of urea-N by small ruminants. The results showed that S improved DM intake, live weight gains and N utilization. N was not retained by goats and sheep on low S diets. Rumenal NH3 N and blood urea were significantly (P < 0.05) affected by S levels. The goats were found to require 0.82 g N d-1 Wkg-0.734 for maintenance. The highest live weight gain and retained N were recorded at the 0.5% supplemental S level, adequate for the 5.7% urea in diets fed to goats and sheep.
