Summary

The effects of giving starch and sulphur, and of the frequency of administration of urea, were measured in N balance experiments with two Rahmany rams. Urea N utilization was greatly improved by dividing a single daily dose into three equal parts. Starch and sulphur also improved the utilization of urea N.
