Four sheep and four crossbred Ongole steers, fitted with rumen cannulas,  were used in a 4*4 Latin square arrangement to study the effects of N sources (urea or Gliricidia sepium leaves) on intake, digestibility and rumen parameters. For the sheep the diets were: JF, free access to rice straw and Jackfruit waste; JF-U, same as JF but with 3% urea (DM basis) added to the jack fruit waste; JF-GS,  same as JF but with fresh leaves of Gliricidia sepium at 3% of live weight; JF-U-GS, same as JF-U but with fresh gliricidia leaves at 3% of live weight. For the steers the diets were: JF; JF-A same as JF but with ammoniated rice straw (3% of straw DM); JF-U; and JF-MUC, same as JF but with free access to a soft molasses-urea cake (10% urea).
