When sugarcane was chopped, supplemented with meat meal or the tropical legume Leucaena leucocephala and fed to Droughtmaster steers, they gained liveweight at the rate of 0.61 kg day-1. When non-protein N and S were used as the supplement, animals lost liveweight /kg LW0.75 per day and digested 57.9% of the diet when the protein source was L. leucocephala, 64.4% when it was meat meal and 66.2% when it was urea and sodium sulphate. The differences in digestibility were associated with differences in retention time of the diets in the rumen.
